"Tell me what temperature of flame should be used when you want to make a tertiary alloy molten state. Tolstoy asked, standing next to the hammer.

"The optimal temperature for a tertiary alloy to be molten is 1,300 degrees. As he manipulated the hammer to forge a piece of metal, he had to answer Tolstoy's questions. Whether it was controlling the hammer or searching for memories in his head, both were extremely draining, and beads of sweat appeared on his forehead.

"Then tell me why I want to keep this temperature value of 1,300. Tolstoy did not spare any safety and continued to ask deeper questions on the basis of the previous question.

"Below this temperature, the metal will not melt completely, and there will be some fine unmelted particles, which will break up during the forging process, and will create cracks in the metal that are not visible to the naked eye, affecting the strength of the metal. Temperatures above this level will destroy the molecules of the metal itself, which will also affect the strength of the metal. After answering this question, he hurriedly grabbed the metal strips on the impact hammer with pliers and turned them over one by one.

Just now I was patronizing to answer Tolstoy's question, and I almost knocked on the head.

Gloomily relieved, who hurriedly saved the metal bar from under the impact hammer.

This is his final exam, as long as he can complete it, it means that he can leave the school, but the difficulty of completing it is really high enough, and no mistakes are allowed at all, otherwise it will be considered a failure in the assessment.

Just like the situation just now, as long as the impact hammer hammer is hammered more, the appearance and shape of the metal bar will change slightly, and the metal bar will be made into a short knife, and the spine of the knife will be hammered just now, if it is hammered more, it will cause skew. A little crookedness may not be visible to outsiders, but in Tolstoy's hands, any flaw will be discovered by him, and then a big red stamp of "failing" will be stamped with it.

Just a little bit, Glow has to put down what he has at hand, and then "go back to the furnace and rebuild".

In addition to Tolstoy, Fat Tiger and Reeser were also watching.

"Yes, yes, the reaction is fast enough, I thought you were going to be unqualified because of the extra hammer. Tolstoy nodded approvingly as he quickly turned the metal strip off the machine, "A good blacksmith needs sharp eyes and quick skills. ”

As he spoke, Gmy had already put the underheated metal strip back into the furnace to heat it up, waiting for the next forging time.

"Oh my God, it's so hard, if it were me, I wouldn't have gotten to this level. There can't be a single mistake...... Reeser, I really admire you forgers, it's so difficult to even take an exam!" Fat Tiger looked at the danger in the dark, and couldn't help but admire Resor Reisser, who was also a forger beside him.

"Actually, not every forging master needs to go through such an assessment," Rayser looked at the gloomy performance in the field, a little jealous, a little admired, and a little nervous, "My final assessment is not so difficult, as long as I don't make more than three mistakes." This assessment may be the most difficult forger assessment in history, not a single mistake is allowed, and I don't know what the teacher thinks, is it necessary to make the assessment so harsh?"

"Huh?" Fat Tiger was stunned, "You said that my boss's assessment is not the same as yours, and the assessment you completed before was not so difficult?"

"That's right, the difficulty of the assessment I completed before is not so difficult, I only need to make no more than three mistakes to get out of the class, and even if my assessment is placed in other forgers, it is also a top difficulty assessment task. If my assessment is difficult, then the assessment is hellish now. "The difficulty of the assessment he's undergoing now makes me feel palpitations." If I had done it in the past, I wouldn't be 100% sure that it would have been done. ”

"It's too perverted, isn't it! Could it be that Master Tolstoy has taken a fancy to my boss and is unwilling to let my boss go out?" Fat Tiger shook his head as he watched Dian take out the reheated metal strip from the furnace with pliers, and said with a speechless expression.

"I can't rule out this possibility, Senior Brother Di's talent is really strong, and even I feel jealous of his almost demonic learning speed, maybe the teacher just took a fancy to this and wanted to accept him as a closed disciple, give him everything he could in his life, and cultivate a forging grandmaster again. Rayser nodded in agreement.

Inside the forge floor, the metal bar was once again taken out of the furnace, and the blaster hammer roared again.

Gloomy put the heated metal strip under the hammer again, and began forging again. In the meantime, Tolstoy still did not let him go, and the questions were raised one after another.

"If you were to make a heavy weapon, such as a large axe, what kind of metal would you choose for the body of the weapon?"

"I will choose to use the alloy of the sixth series, maybe I will use Yan steel and diamond iron as the main materials of the alloy, supplemented by stardust and thousands of catties of sodium, so that the weight of this weapon will be very amazing, and if you go down with an axe, the human and horse harness will be broken, which is definitely suitable for those big guys. Gloomy replied.

"Very well, so what materials would you choose to make small arms, such as daggers and bayonets?" asked Tolstoy again.

"If you want to make a light weapon that requires a quick attack, such as a short knife or a bayonet, then the most important thing to use is Bronze Blast, and with the addition of Radiant Iron or Shadow Iron, it is very light, but it definitely feels very good. ”

If you want to use light weapons, you are definitely an expert, after all, the most used weapons by assassins are light weapons, short knives, short swords, and daggers are the standard weapons of assassins, so you have worked hard in forging small arms.

"Good, good, I'm done with my question. Tolstoy said with satisfaction, "I won't embarrass you anymore." ”

"Teacher, what you said is light. I've already done it here, and you said that as long as I forge this short knife, the assessment will be over, do you want to break your promise and continue to ask me questions after the forging is over?"

"Uh...... Then you didn't say anything to me. Tolstoy twisted his head to the side in embarrassment and said, "Okay, my little disciple Dark, congratulations on your successful mastering, this is your forging badge." ”

Tolstoy had a green second-class blacksmith badge in his palm, which he had decided after various evaluations, which was neither too high nor too low for a novice.

"Ah, thank you, teacher. ”
