The old dwarf was confused by Gu Yi's blind trick of changing concepts, because there are actually people in charge of research, and their status is indeed much higher than that of ordinary craftsmen, and the treatment of "mental workers" is definitely better than that of "manual workers".

But the problem is that those who can create new things out of nothing are all highly respected and skilled masters, but Gu Yi doesn't look like a master of both virtue and art.

But Gu Yi's string of terms such as "stress, tension, annealing, normalizing, quenching, tempering, heat treatment", although I don't understand it, it feels so powerful, it doesn't look like it's nonsense.

The old man has been dealing with iron all his life, although he doesn't understand, but he vaguely feels that these terms are extremely quintessential, and they exhaust the ingenuity in the wrought iron making art, and it seems to be very consistent with the wrought iron making methods he usually uses.

He is the kind of person who "can only do, not speak", but to be a famous craftsman of the previous generation, he naturally has his own set of secret skills for processing ore and iron, and the iron forging skills he usually uses happen to fit those terms

Although the old man did not understand the exact meaning of these terms, when he was forging iron, in order to improve the "rigidity" of the iron, he burned the iron red and put it into the ice fountain to quench it quickly.

And sometimes in order to improve the "flexibility" of the iron, he will put the iron back into the fire fountain and reheat, which is not in line with the so-called "tempering"?

But what is the meaning of "annealing" and "normalizing"? I think it is also a manufacturing method similar to "quenching" and "tempering", right?

What should be the explanation of "stress" and "tension"? Isn't it the secret technique of wrought iron?

And the sentence "heat treatment process" seems to include these kinds of manufacturing techniques, which happens to describe what he has been vaguely comprehending, but it is so biased that it is impossible to enter.

Gu Yi's few words were like a person who was poor in words and couldn't describe what he was thinking about, and suddenly someone told him the word that he couldn't think of, and he couldn't wait to echo a few sentences loudly: yes, yes, yes, that's it

This made him a little overjoyed, and he wanted Gu Yi to explain it in detail, but he couldn't say it because of his face, which caused his momentum to weaken involuntarily, and he secretly thought: Could it be that as this kid said, 丨Tianji Pavilion丨It's just a 丨Tiangongmen丨 Engineering Academy丨?

"You only know that quenching can make iron hard, tempering can make iron flexible, so do you know what is called 'single-medium quenching,'?"

Gu Yi saw the old dwarf's itchy and unbearable appearance of scratching his ears and cheeks, and he didn't say anything, and pointed to the old dwarf's workbench: "What is dual-medium quenching, what is grade quenching, what is is'isothermal quenching, what is 'surface quenching,' what is 'local quenching,..."

"Do you know what is the purpose of quenching? What is the principle? What is the effect of the different liquid materials used in quenching on iron parts? What is the effect of different liquid compositions on iron parts in quenching?"

Seeing the old man's sluggish appearance, Gu Yi smiled evilly, the "brick family mode" was activated, and he walked around in front of the old man with his hands behind his back, and he was very good at teaching the teacher: "Quenching technique, length of time, temperature, size of iron... What is the effect on the performance of iron parts?"

The old dwarf couldn't answer, Gu Yi looked sorry, and shook his head with a sigh: "You don't even know these most basic and simple principles, and you are embarrassed to ask me to read the secret book of "Heavenly Creations"? Even if I show it to you, do you understand it?"

While flickering, Gu Yi secretly observed the old man's expression, and when he saw his collapsed appearance, he snorted twice, and decided to put down a hammer at the end: "At your level, you have actually mixed up with a piece of the Courtyard Monument?

The old dwarf's eyes were blood-red, his nose was snorting and panting, a pair of fists were clenched, and the green tendons on his neck burst into old high, which frightened Gu Yi, don't talk too much, make this old dwarf angry, right?

When Gu Yi was in turmoil, the old dwarf with a struggling face seemed to have made some major decision, and suddenly knelt down with a bang of pushing the golden mountain and falling jade pillar, and a big gift fell to Gu Yi's feet: "Ask the master to accept me"

"What's the matter?"

Gu Yi was dumbfounded, there is no such thing in the script? Shouldn't it be "the lord is on top, and I am worshiped by the old man"?

"Don't Feed Don't Feed Up"

"Ask the master to get started, otherwise the forging will never get up"

He doesn't have any psychological burden to accept the old man as an apprentice or something, the problem is that he doesn't know much about himself, and he completely relies on a little common sense knowledge to fool people, and he really wants to accept the old man as an apprentice, and he can't teach him when the time comes.

Gu Yiyu coughed twice and said, "Uh, what kind of forging is it, right? You see that you are from Tianji Pavilion, I am from Tiangongmen, we are not a system, are you so good?"

The old dwarf said with a serious face: "Qi Yu Master, the method of forging and smelting the art of Kui has reached the realm of Taizong JT, and you can open a courtyard with a monument to open a courtyard, and I am willing to abandon the name of this Taizong and worship under the master as a craftsman and apprentice."

Don't mind, I still expect you to use that iron brand to gather a large group of masters of the Diluo Mountain Kui clan to help

"It's not that I don't want to accept you as an apprentice, ha, it's mainly because we丨Tiangongmen丨What is that... Well, the door rules... Yes, the right door rules, you can't just accept apprentices"

Gu Yi Khan came out, and in a hurry, he had an idea, and said seriously: "Besides, even if you worship under my door, you also belong to the Engineering Academy, not our Research Institute, the learning system is completely different, how can I teach you? I can't learn it..."

The old dwarf was also dumbfounded, and opened his mouth to stammer: "This... How's that okay?"

"My old man has been in this Hollow Valley丨Retreat and enlightenment丨Huang Gong JT realm for more than 20 years, and now I have a chance to break through, how can you not accept me? How can you not accept me? How can you..."

The old dwarf who was sweating in a hurry suddenly jumped up with a hideous face, grabbed Gu Yi's neck and shook it vigorously: "No, you have to accept it, you have to accept it, you have to accept it, you have to accept it... By the way, didn't you say, 'Passing on men but not women, inside but not outside?' My boss will be your son, and if you pass on the "Heavenly Creation" to me, it won't be regarded as an external transmission."

Gu Yi, who was almost shaken and vomited by the old dwarf, sweated violently, and accepted you as a son?

"Wait, wait, you listen to me, we丨Tiangongmen丨's research institute丨Although we don't accept apprentices, you can choose to join us丨Tiangongmen丨's 丨Gongyuan jM"

Gu Yi, who was about to be strangled to death, for the sake of his own life, desperately slapped the old man's big hand that grabbed his neck collar, and shouted: "Although I may not be able to teach you anything, I can guide you to learn a little 丨Engineering Academy丨 Craft."

"What? really?"

The old dwarf with a pair of bull's eyes like copper bells stared at Gu Yi suspiciously, with an expression of "If you dare to lie to me, Lao Tzu will continue to shake".

"You let go, you let go first"

Gu Yi hurriedly struggled to get rid of the old man's clamps, covered his neck and coughed a few times, panting and saying angrily: "You want to strangle me?"

"Boy, what did you just mean?"

The old dwarf who was gearing up stared at Gu Yi with fierce eyes: "Let Lao Kui join you丨Tiangongmen丨, you are willing to teach me the secret book of "Tiangong Kaiwu"?

"Do you think we丨Tiangongmen丨 are so easy to join?

Gu Yi said angrily: "If it weren't for the fact that there is a shortage of manpower now, at your level, if you don't examine it for three or five or eight years, you wouldn't even have the qualifications to be a craftsman and apprentice."

The old dwarf was somewhat unconvinced: "Lao Kui, I am also the Taizong JT realm, if it weren't for the more than 20 years of retreat and enlightenment丨Huanggong JT realm, how could Zhongrong County丨 also be a famous 丨Famous craftsman丨, even your craftsmen and apprentices of Tiangongmen丨?"

Gu Yi rolled his eyes: "Are you still joining us丨Tiangongmen丨?"

"I'm in, I'm in"

The old dwarf immediately laughed: "Teacher... What do I have to call you, old man?"

Gu Yi's eyes rolled and waved his hand: "We are not a system, just call me by my name 'Gu Yi, or Shao Yi, you really don't get used to it, according to the rules of our Tiangong Gate, call me 'Gu Gong, it's okay."

"How good is that, how is it good? Gu Gong, you see that Lao Kui and I can enter the door, but I need to worship the patriarch, but what kind of rituals do I have to perform?"

The old dwarf obviously called a hairless boy "Master", a little bit unspeakable, and rubbed his hands with a sneer, but the master comes first, and these craftsmen, compared to their own skilled people, regardless of their status, age and age, will have enough respect, and will not despise Gu Yi because he is younger than himself.

Therefore, Guan Guyi, who forged Kui and got off the donkey down the slope, called the title of "Gu Gong", and said eagerly: "Also, please tell Gu Gong what rules and constraints we have, and also ask Gu Gong to tell Lao Kui about the origin of our Tiangong Gate..."

"We don't have so many rules and regulations in Tiangongmen, so we don't have to be too restrictive. ”

Suddenly, Gu Yi made up a dripping nonsense, which was a bit embarrassing, so Gu Yi had to say vaguely: "As for the origin of the Tiangongmen丨 or something, you will slowly know the Tao in the future..."
