After Chen Daozi ate and drank, he led Xu Yi to the valley where he often gave lectures. It was only three thousand feet away from the coastline, so it was not considered remote.
Xu Yi was curious, when Chen Daozi waved his hand, a huge bluestone where he was lecturing suddenly cracked, Xu Yi jumped and stared at Chen Daozi in surprise.
Chen Daozi said, "You also know that preaching is not easy. Housing prices in Ink City are high, and renting and selling are not easy, and the coast is all the territory of the management committee, which will be consumed. I am preaching here, and it is very close to the coastline, but People are unpredictable, you will never know what kind of dark thoughts are in the monks listening to you, so I have to prepare."
Xu Yi nodded, "I am also a casual cultivator. I know the suffering of a casual cultivator. If you are not careful, then there is really nothing left."
"Thank you for understanding."
Chen Daozi nodded, and he led Xu Yi all the way to the ground, zigzagging for dozens of feet, and came to a grand hall with a height of seven to eight feet.
The four walls of the hall are covered with dark iron rocks, and the four walls are decorated with several shark teardrops. The soft light fills the entire space, and there is a soft cave in the upper left corner, that's all.
"Where's Tianling?"
Chen Daozi directly hit the crux of the problem.
Xu Yi took out a transparent object that was thinner than a hair and only the length of a little finger, and spread it out in his hand.
Chen Daozi's eyes lit up, he stared at Tianling in a daze, and sighed, "I have other raw materials, I have to make the simplest flying knife today, it only needs to hold one Tianling. "
As he said that, he took out the bathtub, took a bath and changed clothes, burned incense and prayed. After a series of procedures, he sat on the futon in the hall, and with a big wave of his hand, a cauldron with emptied spiritual power appeared on the ground, In an instant, a ray of reddish breath escaped from his hand and rushed straight to the virtual cauldron, and then he threw a white flying knife into the virtual cauldron, and only then did the flying knife enter the cauldron, and started His whole body trembled slightly, and smoke of different colors overflowed. Immediately afterwards, Chen Daozi threw the sky spirit into the cauldron, and began to entangle with the flying knife.
Chen Daozi explained while operating, Xu Yi was like a dead tree, sitting in the corner, motionless.
"...The way of refining equipment, in addition to the knowledge of refining equipment, also has extremely high requirements for mana and corpse energy. For example, the cauldron I inspired, if the mana is thicker, the quality of the cauldron that is activated will be higher. The longer it takes, the more vigorous the corpse aura, especially the cultivators who made corpses, or the monks who killed corpses, their corpse fire is mellow, and it can be used to refine weapons to get twice the result with half the effort... "
"... My flying knife is made of cold iron. It is smelted into corpse energy. It is already considered a magic weapon. In the process of smelting the sky spirit, it will break the original balance of the five elements built inside the flying knife. Therefore, the key now is It is to reconstruct the balance of the five elements. I only try to smelt a sky spirit, which can be regarded as reducing the difficulty of rebuilding the balance of the five elements as much as possible... "
Before Chen Daozi finished speaking, Tianling submerged into the flying knife, and the smoke of different colors floating around the flying knife suddenly disappeared, and Chen Daozi said dejectedly, "Sorry, I still failed. Hey, I am not getting better. At this point, I will not fail."
Not only unwillingness but also resentment flickered in his eyes, what a good opportunity, and it was wasted again.
"It's okay if you don't practice hands-on for three days, let's continue."
Xu Yi took out another Tianling.
Chen Daozi stared round his eyes, "Still practicing?"
"Practice! Why don't you practice!"
"But I have no raw materials."
"I have it here."
As he said that, Xu Yi took out a shiny dagger, "Looking at the material, it shouldn't be inferior to your flying knife, but it's not mixed with corpse aura. I believe that for you, smelting corpse aura is just a matter of moments."
Chen Daozi nodded solemnly, and after a short while, the sacrifice began again.
"... It is really difficult to master the balance of the five elements. In fact, I used to be a talisman master. Basically, the current craftsmen have experience in making talismans and alchemy. Because they are talisman masters and alchemists, they have the best grasp of the balance of the five elements So good, but talisman masters and alchemists, if they reach a high level, they are very popular in themselves, and very few people are willing to switch to become a craftsman, so the grassroots craftsmen are all low-level talisman masters and alchemists... "
"... Tianling smelting into a magic weapon has its own unique rules. I told you about the formation diagram, which is the highest-level magic weapon, and it is only used. The basic magic weapon accommodates ordinary heavenly spirits. Can't reach the array..."
Xu Yi interrupted, "Why is this? If there are thousands of heavenly spirits, don't they need a formation map?"
Chen Daozi said, "Thousands of celestial spirits have gathered to form colored celestial spirits. I told you earlier that when the number reaches a certain level, the celestial spirits will automatically gather and divide into five colors: gold, purple, black, black, and blue."
Xu Yi said, "Is it possible that in that magic weapon, there are both colored celestial spirits and ordinary celestial spirits?"
Chen Daozi said, "It's impossible. Colored celestial spirits will definitely devour ordinary celestial spirits. If a magic weapon contains colored celestial spirits, then every unit combined according to the array must be colored celestial spirits. These , you don’t need to know now, you just need to know that there are two most commonly used structures of ordinary celestial spirits, one is a triangular structure, that is, celestial spirits that are integer multiples of three, forming one side of a triangle with each other, and the other is a pentagram The structure, which is also an integer multiple of five, constitutes each side of the pentagram. Do you know why?"
Xu Yidao, "Could it be because of the stability of the triangle?"
Chen Daozi's eyes widened, "You, you are really different. I have been thinking about this truth for many years before I understand it."
Xu Yi secretly said, "I'm just into mathematics." But he was very modest in his mouth, and asked Chen Daozi to concentrate on refining weapons.
Chen Daozi said, "In the absence of a formation map, these two shapes of magic tanks are used the most, and the number of heavenly spirits they can accommodate can completely reach the limit of the fusion of heavenly spirits into green spirits..."
Suddenly, there was a light puff, and there was no smoke around the dagger. Obviously, failure came again.
Chen Daozi was extremely embarrassed, Xu Yi waved his hand, and took out a dagger and a Tianling.
Chen Daozi felt a little ashamed, took the dagger and Tianling, continued to sacrifice without saying a word, and started narrating again.
Half a stick of incense was not available, and the third sacrificial exercise also failed.
"Take a break, let's continue when you recover. Now, let's see how my sacrifice is going. If there is any problem, you can point it out."
Xu Yi said with a smile, without any distress or boredom on his face.
He let Chen Daozi rest, not because he felt sorry for Tianling, but because he saw that the continuous sacrifices had consumed a lot of Chen Daozi's mana and corpse fire, and it took time to recover.
Chen Daozi was stunned when he heard that, "You, you want to test yourself, this, this..."
