The bronze helmet cast iron has been half a life, not only is it experienced, but his eyes are sharp, and he has already discovered the flaws of Ji Wenming's fat-stealing giant axe in just a moment's groping- When it was first cast, the magician of the desolate world used the bird's beak in reverse in order to follow the shape to exert its power, the tip of the beak was used as the back of the axe, and the end of the beak was used to make the blade of the axe.

He reached out and touched the axe, and soon, patches of red lines lit up on the axe, and the beak of the fat stealing bird was actually reactivated by him.

The bronze helmet said to Ji Wenming: "This demon bird is extraordinary, and it is a pity that the beak of the bird, as the essence of its body, is cast into an axe...... You see, this material is naturally arranged in a neat pattern, extending to the tip, if it is cast into a sword, using this tip as the edge of the sword, with the thick end as the back, is the most suitable casting scheme for it. Cast into an axe, but it was used in reverse, so it can only exert a small part of the power of this bird's beak, which is too wasteful!"

Copper Hammer nodded with a smile, his senior brother is a famous master in the casting industry of the Yuanxia world, and also a representative of the academic school, for the use of materials, the design of weapons is very unique, under normal circumstances, the foundry rarely will analyze the wonders of the material in simple terms to customers, but Xi Wenming is a beginner, and the copper helmet in order to improve his casting literacy, this is such a detailed analysis of the subtleties of the fat stealing giant axe casting.

Ji Wenming looked at the red lines on the surface of the fat stealing giant axe's body like water lines, forming scaly ripples, and the peaks of the ripples were towards the tip of the bird's beak, and he secretly thought in his heart, feeling that what the copper helmet said was very reasonable.

When the fat-stealing demon bird is alive, it also uses its beak as a weapon, which requires the bird's beak to be tough and sharp, and the smaller the head, the more powerful it is, and it is indeed inappropriate to use it to reverse the shape and cast an axe.

In the past, he had never thought about this problem, but now under the guidance of his teacher, he began to learn step by step, which is also the basic design homework of foundry.

Ji Wenming is smart by nature and has the ability to draw inferences, at this moment, he saw clearly, suddenly took out the black rock, and asked: "Uncle Shi, if we smelt it again and make this material and the beak of the demon bird together, can we increase the power of the weapon?"

The bronze helmet smiled and said, "Then it depends on the texture of your piece of material and the level of the foundry!"

After finishing speaking, the bronze helmet took the black rock fragment taken out by Ji Wenming in his hand, looked at it carefully, and seemed to be a little unsure of the ingredients, he put it on the iron felt and hit it with a hammer, and it took a long time to peel off a fragment from it.

The copper helmet put this fragment into the furnace and burned it, the fragment did not change for a long time under the high temperature, it was still black, it seemed to be extremely resistant, the copper helmet was puzzled, turned his head to look at the copper hammer, and asked, "What do you think this should be?

The copper hammer shook his head and said: "I have never seen this substance, if it weren't for the fierce fight between Tongde and the "Ten Thousand Poisonous Scorpion Lion", I am afraid that the boulder would not have been able to break through at all, there are too many secrets hidden in the dark area......"

The bronze helmet waved his hand and beckoned to the two: "It seems that a detailed test must be done, let's go, come to my laboratory!"

At this moment, the apprentices have gone clean, and the long casting process has exhausted them, and they are desperate for a glass of mushroom wine and a warm bed, and the copper helmets and copper hammers are strong, so the spirit is still strong, and the three of them left the casting room and came to a cave next door.

This room was slightly smaller and heavily defended, and when the three-foot-thick magic gold door was opened, there was a row of high shelves made of magic gold, and the shelves were covered with a one-foot square lattice, in which all kinds of rocks, materials, magic gold, and minerals were placed...... The collection of Bronze Helmets is actually more than that of Derek the Harpy.

There are more than 20 of the same high-bay containers, and it is roughly estimated that there are tens of thousands of material specimens in storage, Ji Wenming was a little surprised by the richness of the Yuanxia World, and the bronze helmet proudly showed off: "This is a specimen library that I have collected for many years, and every material is worth exploring in depth! Moreover, there are more than a dozen warehouses for storing various minerals, and I have inventory of most of the materials in the Yuanxia World here!"

Copper Hammer didn't expect that the senior brother had collected so many specimens over the years, and it seemed that while studying casting in depth, he did not let go of the collection of materials.

The copper hammer even saw that at the bottom of each specimen was a fancy and intricate text indicating the time and location where the specimens were collected, and if necessary, they could be used to open up the mining area according to the map at any time.

The three of them walked through dozens of shelves and came to the bottom of the room, where there was a test bench with all kinds of strange instruments stacked on it, and in the dazzled and dizzying eyes of Ji Wenming, the copper helmet first weighed the black rock fragment with something called a scale, and then sank it into the white magic gold solution to measure the density of the black rock, and finally came to an astonishing conclusion that this black rock fragment was extremely dense, far exceeding ordinary magic gold.

The bronze helmet suddenly remembered a specimen, which was very close to the material properties of the black rock fragments, he searched for a moment on the shelf, took out a porcelain-white magic gold nugget with dense holes, and said: "I guess this thing should be magic iron! We all know that the further down it goes, the hotter it gets, so there will be a large amount of lava coming out of the ground, and only hundreds of thousands of zhang of extremely hot underground will there be a magic iron solution, which will be ejected to the ground with the volcanic eruption, forming rocks! ”

The copper hammer frowned, and muttered secretly: "Demon Iron, Demon Iron, does this thing have any strange attributes?"

The bronze helmet sighed heartily: "With the temperature of an ordinary furnace, this thing can't be melted at all, and at present, we don't know anything about this substance except for its high temperature resistance and toughness and sharpness!"

Ji Wenming never thought that the loot he collected casually would be an unknown magic gold substance, seeing the two foundries meditating on this material, he couldn't help but prompt: "If the underground environment is extremely hot, then can we try the low temperature environment? Maybe we can have a different harvest!"

"Low temperatures, you mean the Holy Mountain?" the bronze helmet thought for himself, "The hottest place in the Furnace Fort should be there!"

The copper hammer's eyes lit up and said, "Yes, you can indeed try the reaction of this substance in extreme environments, I think there should be a breakthrough!"

The bronze helmet sighed: "It's a pity that the holy mountain has been listed as a forbidden place by the temple, and you can't approach it without permission, let alone climb to the cold area above!!

Ji Wenming suddenly remembered the holy stone on his body, he took out a crystal clear saltpeter and said to the bronze helmet: "Uncle Shi, I purchased such a stone in the furnace fort, and it will absorb a lot of heat when it encounters water!"

The bronze helmet didn't expect that Ji Wenming also had a hobby of collecting specimens, so he couldn't help but cherish him even more, and said with a smile: "The little nephew also likes to collect these strange stones?
