Since the fuel is related to the follow-up weapons, Shen Cheng checked the buildings. One of the fuel buildings is a fuel-charged building that must be obtained after completing the pre-quest. Buy a water electrolyzer to make hydrogen and oxygen. Keep children away from this building, or you may find out, boom!]
The use of electrolyzed water to produce hydrogen and oxygen is still a technically difficult problem that has not been completely solved in Shen Cheng's world. The main reason is that the initial "electricity" cannot be completely converted into kinetic energy after hydrogen combustion, which is wasted in electrolyzed water Compared with the relatively low energy efficiency, the large amount of energy lost is not even a good deal.
Now that this technology has reached the end of the world when there are a large number of supernatural beings, it has become a good business instead—a lightning-type supernatural being like Chen Feng can complete a large amount of water decomposition in a day, but if there is no If the system provides 100% safe black technology, they may have to worry about the stability of the power input of the supernatural power and whether the hydrogen explosion will blow up the entire research laboratory. But with the support of the system architecture, all these problems no longer exist.
The only problem remains: To buy this building, you must complete a pre-task, which is to buy a sufficient amount of 'platinum'.
[The pre-task of the electrolyzed water room: provide platinum and platinum products with a mass of 20kg.]
"???" I read that right, 20kg
You must know that the production of platinum is much rarer than that of gold. Usually, when you go to a gold shop to buy platinum rings, the weight is calculated in grams. A ring and a necklace don't even use how many grams of platinum, the system is good, 20kg at the opening
This... Even if there is a platinum mine, it will be too late to extract it!
Shen Cheng looked at the 20kg weight for a moment, suspecting that it would be too late to complete the pre-requisite tasks in two days. She looked at other fuel-related buildings and found that most of them were 'pre-conditions not met'.
The oil storage field is more than two days away from them, and the natural gas is not supplied nearby. It seems that hydrolysis electricity has become the only stable fuel solution.
Shen Cheng had no choice but to tell Li Weilan about the pre-mission task, and Li Weilan nodded after listening, without saying a word: "There is a way."
She chose 'electrolyzed water'. According to Li Weilan's scientific knowledge, which is not as good as Fu Yanzhou's, he remembered that one of the requirements for electrolyzed water is to use a platinum alloy catalyst as the base. In this way, although the amount required for the game system sounds huge, it is still Not insane anymore.
Find a way if you have difficulties, she has already made a choice, what he does is to help her complete the pre-mission tasks, you can't just rely on her for everything.
Li Weilan gathered all the people in the base, and as soon as he talked about the current difficulties the base needed, some people in the base immediately took platinum jewelry, rings and other small things from their pockets and put them directly into the box in the hall Lose it and leave.
People in management stopped them, but they became angry --- there is still a certain market for precious jewelry before the end of the world on the wasteland, but no matter what, there is no such thing as the safety and stability that the base provides today. .
Everyone knows that the 'contribution' they usually make to the base is not equal to the equipment such as mechas that can be exchanged for at the exchange point.
Some people originally felt that they had made less contributions to the base. At the moment, they would at most say to the little girl who counted, "It counts as our contribution to the base, can accepting it be considered a contribution?" But more people kept silent. Jewelry was tinkling and thrown into the box. When many people fled for their lives no matter what, they would wear their wedding and engagement rings and carry them close to their bodies in the interlayer.
These things are the last things for emergency rescue, and many people would not have planned to take them out if they didn't feel that the life in the base is really exciting.
Shen Cheng looked at the boxes in the hall of the base that were filled up little by little. Although her task was only to increase at a rate of four to five grams, seven or eight grams, by the end of the base, she could scrape together 2kg of platinum products. , Compared with the total amount of 20kg, it is indeed not much, but watching this scene, my heart is warm.
They were finishing up the accessories, Li Weilan packed all the fruits, meat and medicines he had saved in his space during this period, and went straight out of the base to the tent area.
In fact, the people in the tent area are basically ready to leave.
Noah's base had already sent someone to notify them, saying that the zombies tended to gather towards the base, and those who still wanted to stay and advance with the base could all enter the base.
Faced with the pressure of the siege of zombies, those who are still willing to fight bloody battles with the base naturally don’t have to wait outside. However, the empty beds in the Noah base are filled up quickly, and most of them just want to enter the base and wait and see. After discovering that the situation was indeed wrong, they left early, and now the few remaining are businessmen who hope to make a fortune in war -- some of them carry a large amount of war supplies, hoping to make the last fortune before leaving.
But often, those who have the confidence to stay until this time before preparing to leave are businessmen with certain strength.
After Li Weilan arrived among them, he went straight to the point. He spread out the goods he brought on the floor, looked at the few merchants who surrounded him immediately, and said loudly, "Exchange them all, only platinum products."
"Platinum?" The rest of the dozen or so groups froze for a moment.
No one thought that at this time, Noah didn't take food or weapons, but came to collect unusable precious jewelry
crazy
But what this person took out to exchange is said to be priceless in Noah’s base, and the supply is in short supply. This kind of medicine is said to be a life-saving medicine in the black market. In the last days, there is no more than this. Hard hard currency.
He traded it for platinum
The suspicious gazes of several people only brought Li Weilan a slight smile: "I'm Li Weilan, you should all have heard of my name."
"!!!" Come to Noah for business, how could you not know who he is
Li Weilan smiled: "The tide of zombies doesn't pose too much threat to us. I want to make a piece of jewelry with my own hands to celebrate my mistress. These are all my private shares. You have other choices now. I just want to If you exchange 20kg, you will only exchange it for this day, and it will be over when you exchange the purchase."
To please the hostess
There are only so many cards in Noah's base? Ready to celebrate now? Not worried at all. Will there be any problems
But no matter what, the number of 20kg... Who is not afraid of breaking the neck
The slander is the slander, even if he talks nonsense, it is also an internal matter of Noah's base. If there are people who foolishly exchange war supplies for "precious metals", they can't stop them, can they
"..." Several people looked at each other in dismay, looked at each other for a while, and then swarmed up, each of them began to ask the people around them to take out their precious jewelry, some of them didn't bring these things, and hurriedly ordered their hands to go around Small gatherings to buy and exchange, with one-day round-trip as the boundary.
In the next 24 hours, Shen Cheng watched the completion of the task increase a little bit, and reached the peak after 12 hours. It seems that all the platinum products from the nearby gathering places were bought.
Just in the middle of the task, Fu Yanzhou, who was already shaking and dizzy, finished studying the furs of the three mutated animals that Li Weilan brought back to the base, determined the methods of cutting, tanning and sewing them, and determined How much defense can be added and how much protection can be provided by the leather armor made of them.
When he came out of the laboratory, his face was already very pale. He hadn't eaten, drank or slept for more than a day. Even a research madman couldn't bear it. Fu Yanzhou had dark circles under his eyes. He probably could go out and act without makeup. Panda is gone.
Fu Yanzhou didn't cry out.
But when he walked out of the research room, he was dizzy and dizzy for a while, and his eyes were dark, until Xi Bei happened to see it when he passed by the next door.
Seeing him staggering and almost falling down, Xi Bei never expected that a psychic supernatural being could turn himself into Sister Lin. He supported him, but his tone of voice was somewhat dissatisfied: "Fu Yanzhou, what have you done?"
Fu Yanzhou only felt a buzzing in his ears, he supported the wall and then came back to his senses, and when he saw Xi Bei's face clearly, he said slowly: "My work is done, it's time to go back and rest .”
He slept in a single-person suite, and Xi Bei was a little worried, so he helped him to lie down on the bed in the room, looked at his exhausted appearance, sighed secretly, and couldn't help persuading him: "You don't have to be like this... It’s like dying in a minute. If you die, it will be a great loss to the base.”
Fu Yanzhou opened his eyes on the bed.
The ceiling is a cold blue-gray.
It's not his favorite white, but it can be regarded as simple and clean after all, which is good enough: "You don't understand, I'm... atonement."
"Atonement?" Xi Bei really didn't quite understand what he was talking about.
"Yes, atonement." Fu Yanzhou opened his eyes, "Maybe others can ignore it, but for me, my heart can never be at peace. I can't be at peace."
Xi Bei didn't know what he was talking about, she frowned vaguely, wanted to persuade but didn't know where to start.
Speaking for herself, her opinion of Fu Yanzhou was just flattery at first, but now, it can only be said that she loves Fu Yanzhou more than admiration.
She didn't know what Fu Yanzhou's crazy research on the so-called 'atonement' was for, but in her opinion, this kind of atonement, which was almost self-torturing, could already be called a mental illness.
It's not healthy.
Xi Bei hesitated to speak, because she could see that Fu Yanzhou's eyes were full of determination, which was a kind of persistence that she couldn't persuade.
Such a person... Xi Bei sighed and closed the door of Fu Yanzhou's room.
**
After Fu Yanzhou's research is completed, the [Equipment Building Room] on Shen Cheng's phone can be built.
The construction price is 100G, or 100kg of refined metal, and 100Kg of wood. If it is not facing the urgent situation of zombies attacking the city, Shen Cheng should choose to let the little people in the base slowly collect materials. Metals can be refined, but now that time is running out, she chose krypton gold.
Soon, everyone in the base heard the voice of the system machinery: "The base is open: the equipment manufacturing room. Residents in need, please bring your raw materials and contribution points, and go to the manufacturing room to complete the tailoring."
"!!" Raw material? Contribution points
The latter is something that almost all welfare buildings on the base need, but raw materials
When some people thought about it, they thought of the materials on the mutant beasts that had just been put into storage in the warehouse of the base. Some people contributed a lot, so they went to exchange some mouse skin and mouse teeth. They were still thinking about the base. Why did such a batch of products suddenly appear on the shelves? It turned out to be used here!
