Lin Xiuxian chuckled and said, "This thing is not easy to get. Some time ago, a knight came back from the Diyuan Realm, and he found a small part of it in the Diyuan Realm and brought it back, and deposited it with a friend of mine for sale. See if it's enough!"
Lin Xiuxian said and handed over the lead cylinder.
Zhang Tie took the lead tube and unscrewed it. A golden crystal as big as a fist floated out of the tube. Like a balloon that escaped from a child's hand, it floated directly towards the ceiling. Zhang Tie With his quick hands, Tie Yan grabbed the crystal and covered the lead cylinder in one fell swoop.
"Be careful, if this thing really floats away, there's nothing I can do about it..." Lin Xiuxian reminded quickly.
Zhang Tie nodded, held the fist-sized crystal with his hand, and looked at it seriously.
The fist-sized crystal is like a combination of gold and crystal. It has the texture and luster of metal, but also has a translucent color. What's even more amazing is that this thing will float away as soon as you loosen your hand. Even if you hold it at the moment, Zhang Tie can still feel its eagerness to break free from his grasp.
This is metal, the most expensive and mysterious metal in the world today. The raw material used by the Taixia royal family to make the core components of the flying boat - floating gold.
Even Zhang Tie saw what the raw gold mine looked like for the first time.
"How many more are in the lead cylinder?"
"There are 7 more of the same size!"
"Okay, thank you..." Zhang Tie said, unscrewing the lead cylinder, stuffing the empty floating gold that was about to float away again into it, then taking the lead cylinder over and putting it directly into a space on his hand. Inside the ring, strangely enough, the floating gold that was struggling to fly away in his hand suddenly became solid as soon as it was placed in the lead cylinder, and just floated quietly.
Then Zhang Tie directly took out fourteen earth element crystals from the space ring he was wearing and pushed them in front of Lin Xiuxian.
During this process, Lin Xiuxian and Zhu Daqian looked at the space ring on Zhang Tie's hand with unabashed astonishment, watching Zhang Tie take things out of the space ring and then put them back in. It's like magic.
Space equipment that even knights find rare is even more extraordinary to these rune alchemists, ever since Zhang Tie revealed the space ring he was wearing on his hand in front of two people for the first time. The two people were restrained.
"Grandma, when I get rich and become a craftsman in the future, I will also get a portable space equipment to wear..." Lin Xiuxian said, and his hands were not slow. Instead, he quickly put the earth element crystals that Zhang Tie took out into a storage bag that he carried with him. It must be the space ring. These element crystals are also very eye-catching.
"If you want to become the Craftsman Sect, you still don't know that you have to wait until the Year of the Monkey and the Horse. To be practical, why don't we save enough Earth Element Crystals and go to Taiyi City to try our luck at opening two Secret Treasure Pearls!" He glanced hard at the space ring on Zhang Tie's hand, and then said.
"The space ring on your hand is too eye-catching. It doesn't matter if you are in Tiangong City. If you want to leave the city,
. You must be careful. The knights will be jealous after seeing this thing. You are a strong warrior at level 10. If someone steals your things, you will destroy the corpses and traces without blinking an eyelid. If there is a demon in the human heart, then act like a demon. Yeah, this space equipment of yours is so mesmerizing! " Lin Xiuxian, who put away the Earth Element Crystal, also reminded Zhang Tie.
"Thank you, Brother Lin, for reminding me. I know that I can do some cross-dressing. If I go outside, I will protect myself!" Zhang Tie said with a faint smile. "It's just empty gold. I wonder if Brother Lin has the means to get some more. The price is easy to say!"
"This empty gold is a product of the Diyuan world. The largest empty gold mine in the Diyuan world is in the hands of the Taixia royal family. Apart from the Taixia royal family, how can anyone else get a large amount of empty gold. Just me. What I just brought here was a knight who was lucky enough to dig it out of a mine in the Diyuan Realm. Besides, except for the Taixia royal family, ordinary people would not have much use for this floating gold. The secret method of making a flying boat from floating gold is, They are all in the hands of the Taixia royal family!" Lin Xiuxian gave Zhang Tie a serious look, "For us rune refiners, the compatibility of the floating gold runes is too poor, and it cannot be fused with other metals. I barely made a set of equipment made of floating gold, but it couldn't be used. Wearing it was like flying a kite. It was not up to me how to move it. In the past, there was a rune refiner in Tiangong City who made a pair of wings using floating gold. I put the equipment on myself and it looked majestic, but in the end because it was difficult to control the direction in the sky, the rune refiner almost threw himself to death. Why do you need so much empty gold... "
"To be honest, I am planning to design a new set of steam centrifugal cannons recently. Now the heat and durability of the main shaft bearing of the steam centrifugal cannon is a big problem when running at high speed. I am going to collect some floating gold to make a set that can carry high-speed Speed, air-floating gold suspension bearing with zero wear and high durability..." Zhang Tie said as he started drawing on the tabletop of the table where several people were drinking.
This bar is a bar specifically for rune refiners to gather. When the rune refiners gather together, it is common to discuss various armed equipment and design drawings, so the top of the table here is a magnetic rune drawing platform. Whoever gets the inspiration Now, you can draw what is in your head on the desktop at any time, so that people around you can discuss it together.
Zhang Tie drew a simple design concept of his own steam centrifugal cannon on the desktop.
Although the things on the table were casually drawn by Zhang Tie, as a rune refiner with basic skills, the things Zhang Tie drew were like drawings made by other designers using drawing tools such as rulers and compasses. The lines were so straight. There were no wrinkles at all, and the shape was so round that there was no fault in it. In less than a minute, Zhang Tie drew a rough design sketch of the steam centrifugal cannon on the table and wrote down the rough parameters. symbol.
Lin Xiuxian and Zhu Daqian looked at the image drawn by Zhang Tie seriously. They frowned and thought while looking at it. After a long time, Zhu Daqian touched his chin and asked Zhang Tie directly, "This design of yours is quite interesting. I The main turntable of your steam centrifugal cannon is closer to the traditional energy storage flywheel design. This design must allow the flywheel to run in a vacuum, so that the energy loss when the flywheel is running can be minimized, and a non-contact suspension main bearing is used. , although this can maximize the speed of the flywheel and increase the speed of the fired ammunition, the investment will also increase many times accordingly.
. In particular, the suspended main bearing must be made of floating gold material, which is completely uneconomical in terms of input and output scale. If you have the time and effort to make this thing, ordinary steam centrifugal cannons can make more than ten. The blowing effect is several times that of this. Do you want to use this thing to participate in the steam centrifugal range competition held every year by the Rune Refiner Association..." At this point, Zhu Daqian looked at Zhang Tie seriously again, and then shook it himself Shaking his head, "It shouldn't be either. That kind of competition is only attended by rune refiners below the rank of secret rune craftsman. Lao Tie, you still need to join in such fun... "
"No..." Lin Xiuxian's eyes suddenly flashed, "Old Tie, you still have a hand here..." Lin Xiuxian's hand also clicked on the desktop map drawn by Zhang Tie, "Old Tie, you seem to have a hand here. One thing is not drawn..."
Zhang Tie sighed secretly in his heart. He was indeed a veteran who had stayed in Tiangong City for decades. His insight was indeed extraordinary. He just looked at the rough sketch in front of him, a function he had reserved in the sketch. The interface of the module has already been seen.
Now that Lin Xiuxian has seen it. Then Zhang Tie had nothing to hide, so he simply took action again and drew something where Lin Xiuxian pointed, adding a common symbol used by rune refiners to communicate.
"A high-speed air-floating gold vacuum flywheel centrifugal disc, coupled with an explosive high-pressure steam propulsion valve. Even if the cost of this thing is very high, it should be enough to kill a war spirit level master. However. Even if it is necessary Killing the war spirits seems to be a bit of a fuss..." Lin Xiuxian suddenly looked at Zhang Tie with wide eyes, "Do you also want to make a steam centrifugal cannon that can kill knights, Lao Tie?"
Zhang Tie rubbed his face, "What do you call it?"
"Because it is almost a similar design. I have seen it decades ago. It was designed by my master, but it was not successful in the end!" Lin Xiuxian sighed and stretched out his hand to perfect Zhang Tie's sketch. "I was still young at that time, and my master was already a master craftsman. At that time, he also had an ambition to create equipment and weapons that could kill knights. In the end, he chose the steam centrifugal cannon as a breakthrough. At that time, my master also chose the flywheel structure of the steam centrifugal cannon. At that time, my master’s idea was that the maximum speed of the flywheel could reach 200,000 revolutions per minute. If a flywheel with a diameter of several hundred meters could be made, then the speed of such a flywheel could reach 200,000 revolutions per minute. At this time, the linear speed of the flywheel edge will likely reach a terrifying level. Anything thrown by the flywheel at this speed will have huge kinetic energy. When this huge kinetic energy reaches a certain level, it can kill the knight. ,but… "
"But did your master finally discover that the mechanical linear speed at the edge of any flywheel can only be below the speed of sound? It can be infinitely close, but it cannot exceed it. The theoretical speed of a 200,000-rpm flywheel is only limited to a small speed in a vacuum. Diameter flywheel, once the flywheel is directly enlarged, its physical limit will come!" Zhang Tie smiled bitterly and said.
"Yes, that's exactly it. Later, my master came up with another way, which is to give a boost to the steam centrifugal cannon at the moment it leaves the flywheel turntable, that is, to add an explosive high-pressure steam propulsion valve at this position. , but even so, after my master has worked hard for this for twenty years, the best result he can finally achieve is to make the muzzle velocity of the artillery shell reach about 1,700 meters per second, which is only equivalent to five times the speed of sound. A steam centrifugal cannon with this speed The attack can kill the war spirit, but it still cannot kill the knight... "
"and after?"
Lin Xiuxian pursed his lips and his eyes turned red, "That old guy was unwilling to give in and finally thought of a way. He actually abandoned the design of the explosive high-pressure steam propulsion valve and wanted to use the explosion of pure alchemical bombs to increase the initial velocity of the steam centrifugal cannon. , after several experiments, there was an accident in one experiment, and I blew myself up, and finally left me alone in Tiangong City.
! "Lin Xiuxian looked at Zhang Tie and said seriously, "Old Tie, I know you are not short of money, but many talented rune refiners want to take this path. They all want to leave a name in history and become a human rune refiner. The pinnacle of weapon masters, but no one has succeeded..."
Zhang Tie knew that Lin Xiuxian was telling the truth, because what he said were exactly the results that Zhang Tie had obtained in the laboratory and in the Black Iron Castle in the past two months. The mechanical linear velocity of the steam centrifugal cannon flywheel edge The maximum speed can only be infinitely close to 340 meters per second and cannot be exceeded. The speed increase imposed by the explosive high-pressure steam propulsion valve is limited by the power of the steam explosion. In the end, the maximum muzzle velocity of the flying shell can only be less than 2000 meters per second.
"I still want to try, maybe there is another way!"
"There are two ways, either to allow the mechanical linear speed of the flywheel to exceed the speed of sound, or to provide greater assistance to the steam centrifugal cannon shells. But the limit of the assistance that steam can achieve can already be seen, and the alchemy bomb cannot be used at all. Reliable, its reaction was too violent. Before it could kill the enemy, it killed its own people first... "
"Steam and alchemical bombs aren't the only way!"
"You are right. Before he died, my master had a flashback and had a profound enlightenment. He said that maybe someone could use the rune array to increase the muzzle velocity of the steam centrifugal cannon or break through the maximum mechanical linear speed of the flywheel. But mastering the rune array is The skills of the top divine craftsman among the rune refiners, the entire Taixia divine craftsman level one, can be counted in two hands, and more importantly, all the rune refiners that can be used by the rune refiners now. There is no rune that can increase the speed of non-living objects. Now the Rune Refiner Guild devotes great efforts to the Earth Yuan Realm every year. It wants to find such ancient runes from the Earth Yuan Realm, but there has never been any gain. , I even doubt whether such runes existed even in ancient times. The path you want to take, old iron, will be very, very difficult... "
"I know it will be very, very difficult, but there are at least two ways in front of me to continue walking. If I don't give it a try, I will be a little unwilling. I will just do my best and obey fate!" Zhang Tie also sighed.
these two months. After repeated attempts and repeated failures, Zhang Tie's obsession has not changed, but he has a clearer understanding of what kind of road he is facing, and if this road is really so easy to walk. To be honest, I'm afraid it has been done countless times by others, and it's not Zhang Tie's turn to try again now.
"Then I can only wish you good luck. I will leave Tiangong City in a few days and go to Yunzhou. The Meng Family of Hongshengtang in Yunzhou City is going to build a Class A city. An elder of the Meng Family and I have a little relationship Friendship, he asked me to take charge of setting up the city defense system of the Meng Family City, and offered me a reward of 1 million gold coins. I will also earn some pocket money for myself. Today is also a farewell to you two... "
Zhu Daqian also smiled bitterly, "You also accepted the job? I may go to Bingzhou City to report in two days!"
"What's your business?"
"Didn't I tinker with the design of a small nitrogen separator before? I also have some experience in separating nitrogen from the air. I originally thought that this thing was of little use. Unexpectedly, yesterday an official who was working in the general camp found Tiangong. City, invited me to a military factory in Huanzhou to participate in the design of a weapons project... "
Unexpectedly, Zhu Daqian's matter was related to him. Zhang Tie could only sigh that the world is really too small. The person who came to see Zhu Daqian was naturally not arranged by him. He was probably Lu Yanyu's subordinate. At this time, Zhang Tie was all Don't know what to say
.
"What weapons project?"
"The fire-breathing tank uses candle oil, and I am responsible for the nitrogen liquefaction device part of the tank!"
"Fire-breathing tank?" Lin Xiuxian was obviously shocked, but Zhang Tie was calm because this was something he had expected. When Zhulong leader took out those candle oil weapons, he thought of Yitaixia's strength and With strength, he will naturally find ways to create more powerful weapons. He is just the beginning.
"Of course, if you look at the situation in several states in the war zone, candle oil production bases are being built everywhere. The fields are filled with fermentation tanks and earthworm breeding ponds for Qianji Zhenren's earth wine. This scene is simply incredible. It was more lively than when there was no war. This Qianji Zhenren was really unpredictable. Originally, the territory of several states was still full of gloom and mist. He had only taken over as General Weiji for a few months, and the people in the four states of Huanbing and Kangning were almost in despair. They were all wiped out. The common people, wealthy families, and officials were all enthusiastic. Many factories in Tiangong City began to study candle oil weapons. No wonder such a person could be selected as General Zhiji by Great Sima An. !" Zhu Daqian said with a look of reverence.
"Ahem, Master Qianji may just be lucky. I heard that that person is still young and doesn't understand anything!" Zhang Tie coughed twice and said.
"Hahaha, Lao Tie, we all know that you are high-spirited, but this Qianji Zhenren is indeed a true hero, kind and righteous, and his achievements and reputation are really beyond what you and I can match. I heard that he is in Youyou There is also an Iron Dragon Sect in the state. When you were not here last year, Lao Zhu and I were discussing that if we got tired of staying in Tiangong City, we might as well go to Youzhou to eat with the Iron Dragon Sect. With our With his ability, he probably won’t be turned away..." Lin Xiuxian said with a laugh.
"With the abilities of these two brothers, if we really get to the Iron Dragon Sect, Master Qianji will definitely open a court for these two brothers and let them take charge of their own affairs!" Zhang Tie also smiled.
"Hahaha, thank you for your kind words, Lao Tie. By the way, how long will you stay in Tiangong City? If you stay for a long time, I will introduce a few friends to you in two days... "
"I'm almost leaving Tiangong City. I've been here for more than two months and I've gained a lot. Some things really can't be rushed. I can only find solutions slowly and step by step. The world is getting more and more chaotic now. , if the thing I mentioned is not there yet, I want to improve my strength first, practice seriously for a while, and strive to advance to the first level as soon as possible, it is not a bad thing!"
This time he came to Tiangong City and stayed in Tiangong City for two months. Zhang Tie's biggest gain was that he understood the difficulties and obstacles that he had to overcome in order to realize his idea. That cannot be accomplished in one day. The solution was not even something that his current level of rune refining could solve. After understanding this, Zhang Tie already had the intention to leave, and there was little point in staying in Tiangong City.
He is not needed for things in the rear now. All aspects have basically been arranged properly. Everything is going step by step and there will be no big mistakes. Therefore, Zhang Tie wants to go deep into the war zone alone. For no other reason than to advance himself to Phantom. Knights are the most important thing. In Zhang Tie's eyes, all ambition and generals are just empty names. Others can give it to you today and take it away tomorrow. A little vanity in the officialdom is really nothing to Zhang Tie. Meng Shidao is still eyeing Xuanyuan Hill, so Zhang Tie doesn't want to get too involved in Taixia's officialdom. This is not a good thing for him.
.
For a knight, strength and rank are the biggest reliance. This time, if you go deep into the war zone, at the worst, you can kill a few more demon knights, or cause trouble for the demons and Tongtian Sect, so as to reduce some pressure on the rear. , in the past two months, although Taixia has recovered from the situation in the war zone, it is still not optimistic. As a knight, it is really difficult for Zhang Tie to be able to stay idle at this time... (~^~)
