Among the components of common super-tough alloys, there will be chromium, titanium, nickel, zirconium, beryllium and other metals, and the super-strong alloys made by modern technology can almost be said to be indestructible at room temperature.

It is not easy to refine the high purity of rare metals, beryllium metal, generally in the form of beryl and chrysoberyl, with a crustal content of 0.001%, and there are very few auxiliary materials in front of Yue Heng.

The zirconium metal is close to 1900 degrees of high temperature melting point of the elements, far more than the melting point of fine iron 1500 degrees, which puts forward higher requirements for the forging process, to purify these rare metal elements, and then into various compounds, it is not difficult.

And the three-born dragon tortoise carapace is a biological material, whether it can withstand the fierce fire smelting of more than 1,500 degrees, and whether it can truly merge with the metal liquid, it is natural, Yue Heng himself is not sure.

"It's not my material anyway, and if it's ruined, it's ruined. ”

Yue Heng took a breath, simulated the entire forging process in his mind, and opened the furnace for forging after confirming that it was correct.

After the independent room is closed, there is a small world, Yue Heng and Xiao Dunzi The door is closed, outsiders can only see the smoke and flame of the forge constantly spewing hot gas, the ventilation window on the door is fully open, and the fog is entangled, but they can't see what people are doing.

Master Zhou stood in front of Yue Heng's forging furnace, he didn't have any hope of forging by himself, he simply handed over the daily forging task to the apprentice, stayed in front of the independent house by himself, and discussed with other masters.

Master Qi also knows about the Craftsman Rank Rating Competition, he and Master Zhou have both been in the third-level craftsman rank for many years, and this year they are ready to hit the fourth-level craftsman rank, and they have also signed up.

thought of Yue Heng's bad attitude towards Chen Haibao. Master Zhou became worried: "This year's craftsman rank rating competition. Master Chen must have signed up for Xiao Luo. There are seven major business alliances on Luohui Island. There are more than 20 sects and parents who have formed the craftsman department, and there are countless craftsmen with good talents. ”

Master Qi said disdainfully: "Isn't this what Master Chen is best at? It may even be rated as level 4 or above, which will directly lead to a real change in the Seiko Workshop!"

Master Zhou smiled bitterly: "Wouldn't it be too rash to let someone who is so young and has just been in the Seiko Workshop for a month lead the Seiko Workshop?"

Master Qi pushed him and said unhappily: "Master Chen is thinking like this, that's why he will target Master Xiao Luo everywhere, are you Master Chen's person?"

Master Zhou said embarrassedly: "If you are quick to talk for a while, you shouldn't say such things, we should be full of confidence in Master Xiao Luo." Alas, you see, the stone door opened, and Master Xiao Luo came out. Look what new weapon he's holding!"

Yue Heng held a shield in his left hand. Holding the handle of the scabbard in his right hand, he walked out with a smile on his face.

This is a typical low-ranking infantry attire of the army. Let everyone be stunned.

This style of painting is different from the previous few days, how did you go from a ranger hero who went to the end of the world with a sword to instantly become a shield soldier with a bloody and tired face?

The long sword is the most mainstream portable weapon worn by the rangers in the Zhongyuan World, and there are slightly fewer people who choose the Pu knife and lancet, and there are even fewer weapons such as spears and spunlace iron rods, and even fewer people who hold shields.

In the martial arts profession, when the left and right hands are held together, the flexibility of the shield knife is far less than that of the double sword, and it is also smaller than the chain of swords, and the lethality is not as good as that of a two-handed attack.

The only consolation is the advantage of shield soldiers in the army, shield knife soldiers have the advantage of large-scale clusters and have a high survival rate, but this kind of cannon fodder is the lowest threshold, the most common and common, the lowest status, and is a thankless type.

"This is the weapon of the shield soldier? Am I not mistaken? The lowest status in the army, always the cannon fodder in the first row of the battlefield?"

"Master Xiao Luo, this is planning to customize weapons for the army in batches?"

In the midst of everyone's incomprehension, Chen Haibao let out a miserable cry, which instantly detonated the audience: "Bastard! Look what you have ruined the three-life dragon tortoise carapace! My dragon tortoise carapace!"

Wow......

The craftsmen and masters who knew more or less about the inside story all exploded, staring at the silver round shield in Yue Heng's hand, their faces full of incredulity.

No way!

Master Luo, did you turn the carapace of the three-life dragon tortoise into an infantry round shield?

Or the lowest level of inlay and forging techniques, you you and you...... Aren't you a tyrannical thing?

Not only Chen Haibao's heart ached, but the other craftsmen also twitched in their hearts, thinking that if I were to deal with it, it would definitely be ten times stronger than Master Luo's shield!

Yue Heng snorted lightly, thinking that the matter was not big enough, he deliberately raised his hand, bent his forearm, waved the silver round shield, and said provocatively: "Your dragon tortoise shell? What a joke! Wang Kuguan personally handed over the dragon tortoise shell to me, and the shopkeeper Jiang did not express any objection, Chen Haibao, you have been spewing blood again and again, if you don't make it clear to me today, I will fight with you!"

Chen Haibao's eyes were red, staring at the round shield in Yue Heng's hand, and he wanted to cry without tears: "Three Dragons and Turtles...... Three-born dragon turtle!"

Master Zhou and other old craftsmen couldn't bear to look at it, after all, they had worked with Chen Haibao for many years and knew what kind of person he was and what kind of things he was good at.

In all fairness, the dragon tortoise carapace, a living biomaterial, is most suitable for grinding, mixing it into molten iron as an additive for overall casting, or secondary processing and carving circles to make original heart goggles or small shields.

Like the one Yue Heng was holding in his hand, in the middle was an original carapace, even the lines were clearly visible, and it was surrounded by a self-expanding silver metal circle, which belonged to the stupidest and most inefficient rough processing in the forging industry.

"Master Xiao Luo is really nonsense, isn't this a waste of the best materials?" Master Qi was a little regretful, shaking his head, thinking that Yue Heng was really a loser.

"According to general experience, as long as there is a large enough external force to hit the round shield, then the serious unevenness of the force will hit this round shield hard, and the carapace will break and separate from the fine iron part, which will not play a protective role, so it is completely meaningless!" The other master also shook his head and sighed, not optimistic about Yue Heng's work.

"How could Shopkeeper Jiang hand over the three-born dragon tortoise shell to him? Who doesn't know that Master Chen is the best Mo family heir in the Seigong Workshop?" This is the old man of Chen Haibao's power, of course he won't say good things about Yue Heng.

Everyone talked about it, overwhelmingly supporting Chen Haibao and not optimistic about Yue Heng's works.

Because everyone's experience tells them that the forging processing method chosen by Yue Heng this time is wrong and the most efficient, don't ask them why they came to this conclusion, anyway, they just know.

Sometimes, experience does matter.

But experience can blind people, don't they? )
