It didn't take long for Ye Yan to prepare a lot of materials for forging Xuan-level equipment and Thundering Hammer for Qin Chen and personally transported them to the room used for assessment. Perhaps because of his willingness, Ye Yan didn't complain about too many materials, nor did he complain that Qin Chen didn't use the small back door he specially prepared for her, when he heard that Qin Chen's required crystal nuclei were raised from the original one to two and asked for an additional fire type demon beast crystal nucleus, Ye Yan knew that Qin Chen's forging strength was not as unbearable as it seemed on the outside, so what Ye Yan had to do was to complete such a mechanic level assessment for Qin Chen according to the procedure, nothing could compare to this. Closing the door, Ye Yan leaned against the wall outside the room, tilting his head and smiling, the curvature of his lips with a hint of imperceptible self-deprecation.

"You shouldn't underestimate anyone...... After gently spitting out such a sentence, Ye Yan stopped talking, just leaned quietly against the wall, waiting for Qin Chen to come out according to the regulations.

"A piece of bronze ore, a piece of silver ore, a piece of ink steel, a piece of rubber raw materials, two thunder-type Warcraft crystal nuclei, and one fire-type Warcraft crystal nucleus, it seems to be quite complete If there is no mistake in the drawing," Qin Chen carefully counted the materials brought to her by Xia Ye Yan, and after confirming that the number recorded on the drawings was almost the same, Qin Chen sat on the table, holding his chin and thinking carefully about the forging plan, but the more he thought about it, the more he found that something was wrong," I know that copper and silver conduct electricity, but ink steel seems to be used for plating to make the durability of equipment better, but it doesn't conduct electricity......! I've never made a hammer...... What about the mold, what about the hammer mold. Why don't you prepare it for me?!! wait! It seems that I didn't use molds when I was forging equipment before. How did I do it at that time? Xuan Shuai's clothes were sewn. The long needles are polished, and the hand crossbows are assembled...... But the hammer can't be assembled...... This ink steel is not stored for molds, is it? Although it is the material for molds...... Forget it...... "After thinking about it carefully, Qin Chen still decided to ask Ye Yan for some more materials, otherwise he really couldn't pass such an assessment, thinking like this, Qin Chen opened the door......

"Mogang wants another piece, and a vat that can smelt copper and silver? Hey Chen'er, don't make trouble, it's just that the fire from coal can't smelt metal at all." What are you using the vats for? After hearing Qin Chen's condition, Ye Yan suddenly knocked Qin Chen's head, causing Qin Chen to hold his head and look at Ye Yan with tears in his eyes. "What's the use of these things! It's easy to do it according to the drawings!"

"People think that there are too many deficiencies in the drawing design, so I want to improve it, Brother Ye Yan, you will give it to me." The direct request was invalid, Qin Chen suddenly turned on the soft girl mode, holding Ye Yan's hand and shaking it back and forth, with a soft coquettishness. It simply made Ye Yan feel more guilty.

"A good drawing has not been suspected for so long, but you girl is suspicious?"

"Not a suspicion. It's just that I want to make it better, because if it's my own use, I have to use something good. ”

"There is no problem with the drawings, and the materials are sufficient, Chen'er, don't make any more trouble!! Hurry up and finish the assessment, and then I'll take you to eat." Suddenly, Ye Yan yelled at him very irritably, I don't know why, I always felt that Qin Chen was making trouble unreasonably, good drawings can play the due effect described on the drawings under the reality of countless mechanics, there can be no other problems. But Ye Yan didn't know, didn't know that Qin Chen's forging knowledge was beyond the forging skills and knowledge of all today's mechanics, although there were not many opportunities to practice, but it did not prevent Qin Chen from judging the defects of other drawings.

"Forget it, I'll figure it out myself, thank you. After that, he closed the door directly with a bang, which made Ye Yan stunned for a while, unable to understand what was going on, and thought hard to no avail, so he gave up continuing to look for the answer, and leaned against the wall again to close his eyes and recuperate.

After closing the door, Qin Chen didn't get much angry, because she knew very well about the backward technology of this world, even if it was prosperous in the primeval period at the beginning, but from Ling Yu, a god-craftsman-level array soul, she knew how unbearable the Heavenly Wind Continent was after the primeval period. There was no other way, Qin Chen had to use other methods to replace the previous idea. After the smelting method that he came up with with to make the best use of his resources was brutally broken by reality, Qin Chen was forced to reluctantly retreat to the next best thing and use the most ordinary tempering method. Bronze ore is not pure copper, and the conductivity is naturally not as sensitive as that of raw copper, so Qin Chen must reduce the bronze to raw copper. The easiest way is to polish, followed by calcination reduction, but it's a different story if you're an alchemist. The reason why alchemy is called alchemy is because when the science of zào was first created, it was to turn base metals into precious metals, which in layman's terms, is to turn stones into gold. However, everything in the world is equal, and it is impossible to save what is obtained out of thin air, and after the countless sacrifices of the group of ancestors who pioneered alchemy, the core rules of alchemy and the rules of equivalent exchange have finally been summed up.

It didn't take long for Qin Chen to carve a very common low-level alchemy array on the ground with an awl, refining the magic array. The steps carried out in alchemy are divided into three steps: analyzing, disintegrating, and reconstructing. Among them, the analysis and disintegration are only two concentric circles in the pattern expression of the alchemy array, the big one is the analysis, the small one is the disintegration, and the gap between the two circles is a complicated reinvention formula, the more complex the formula, the more difficult it is to succeed. However, the refining array cannot be regarded as a real alchemy array, because the steps expressed in the refining array are only analysis and disintegration, and as for reconstruction, there is no need at all.

Refining Circle, which is used to purify metals, but can only refine one metal at a time. It is usually used for rust reduction, bronze reduction, etc. to reduce metal compounds to the state of elemental metals. After carving the refining array, Qin Chen placed the entire bronze ore on the alchemy array, and then put his right hand on the edge of the array, and with a movement of his spiritual sense, the ring of "Natural Contract" worn on his finger instantly emitted a faint white light, only to see the faint white light light lit up from the engraving on the refining array, and it was only a moment before it dimmed again. On the ground, a piece of red metal lay quietly, as if it had appeared out of thin air, while the original green bronze ore had long since disappeared.

"I've wanted to try this alchemy array for a long time, but I didn't expect it to be so useful, tsk. After sighing with emotion, Qin Chen stood up again, picked up the hammer and silver ore on the table and went directly to the smelting table, at this time the furnace fire was blazing, and the scorching heat wave was coming. Qin Chen picked up the pliers, clamped the original copper and put it in the fire to calcine, until it was red, then took it out again, clamped it and put it on the tempering anvil for a while, until the temperature dropped, and then put it into the fire to calcine, so reciprocating, every time it is tempered, the density of copper will increase once, and the time taken to be calcined to red will be extended a lot, even if the bellows are pulled violently and the flame is burned vigorously, it cannot change this fact. After several times, the originally large raw copper became dense and solid under Qin Chen's tempering. After the last tempering, Qin Chen put the silver ore that was put aside on the anvil, the silver ore stored in nature is all elemental, and it is soft but tough silk threads, Qin Chen directly tied the silver wire to the copper block, tied it strongly, impermeable, but Qin Chen did not use all the silver wires, but left a part of it and put it on the table again. Then he grabbed the copper that was tied into a silk cocoon, lifted the sledgehammer, and the continuous hammer sound of "ding, ding, ding, ding......" echoed in the room like a piece of music.

"Sounds like a real skill......" Outside the room, Ye Yan, who was waiting against the wall, listened to the melodic hammering sound, and couldn't help but be a little addicted, as if he was listening to a beautiful music.

In a short time, Qin Chen successfully tempered the two ores to the point of interdependence, and after putting the silver-copper alloy aside, Qin Chen began to carve the alchemy array again. But this time, it was the simplest universal alchemy array carved out of the seal, not why, because the alchemy price this time was almost zero. I saw Qin Chen put the silver-copper alloy in the center of the five-pointed star, and his spiritual sense moved, only to see the "Natural Contract" on his finger and the five-star alchemy array on the ground lit up one after another, and after the light dimmed, the appearance of the silver-copper alloy was simply a world of difference from the appearance that had just been tempered. Under the effect of the five-star alchemy array, the originally irregular block silver-copper alloy turned into a very regular cuboid, and the twelve edges seemed to have been polished, which was very smooth, and on the narrow side of this cuboid, it was very smooth and concave into a depth of half width, and at the end of the hole, there were three standard inlaid holes, which were exactly the same size as the crystal nucleus, in addition, the three inlaid holes were intertwined with several protruding textures, as if the three inlaid holes were linked together. However, the appearance of these textures and these inlays is indeed to make the three inlays connect with each other, these three inlays are for the purpose of inlaying the three crystal nuclei, and the textures are for the energy of the three crystal nuclei to form a circuit.

After putting the formed silver-copper alloy on the tabletop, Qin Chen took the ink steel on the table, put it on the stove that was still burning vigorously, and then returned to the workbench, and inlaid the two thunder-type Warcraft crystal nuclei and the fire-type Warcraft crystal nucleus into the inlay in the order of thunder, fire, and thunder in turn, and then crossed the remaining silver wires around this cuboid, except for the one side with a hole, the other five sides were wrapped with silver wires.

After dealing with these things, Qin Chen returned to the stove, took out the black steel that was burned red in the fire with pliers, and tempered a piece of irregularly shaped ink steel into a long rectangle, and then Anjin formed the silver-copper alloy, and then, he simply pushed the table to the side, and carved a huge five-star alchemy array on the empty ground, and then Qin Chen placed the silver-copper alloy and ink steel in the shape of a hammer in the center of the alchemy array, but this time, Qin Chen also walked into this large alchemy array, and then, a ghostly light flashed......
