Seeing that Lin Su was so persistent, Qin Yu did not continue to dissuade him and directly asked him to move the steel ingot into the house. Pen & Fun & Pavilion www.biquge.info

Qin Yu's house is very large, except for the bedroom, kitchen, dining room and other necessary rooms, the remaining three-quarters of the space is designed as a studio, and it is here that the work of smelting meteorites is completed.

After Lin Su and the others walked into the studio, they saw a room full of iron ingots and more than a dozen forged swords, and the surface of these carefully crafted swords was made of some openings, which looked very incongruous.

"Don't worry, these are the failures of my experiments. Qin Yu casually took aside the debris on the ground and made room for Lin Su to put down the steel ingots he brought.

Qin Yu didn't start the forging work immediately, but took out a shoebox-sized box from the shelf. When opened, the strange tools inside were revealed.

"Do you have any ideas for what kind of kitchen knife you want to make?" Qin Yu asked as he took out his notebook and turned to Sally El and Hodge.

"I came up with the idea of building a kitchen knife like this one. Without hesitation, Sally El took out the kitchen knife she had used before.

"Very good maintenance. Qin Yu glanced at it and exclaimed.

Like Sally El, Hodge took a kitchen knife out of his backpack. However, this kitchen knife was not the one he had used before, but a model that Hodge had made overnight. Knowing that he was coming to see Qin Yu, the world's number one grinder, the Hochitto people used 3D printing technology to turn the kitchen knife they designed into a real thing.

The main body of this kitchen knife is no different from a regular chef's knife, but there is an extra barb on the back of the knife, and the quarter of the tip of the knife is designed with some small circular holes. The whole kitchen knife was inspired by Hodge's extensive cooking experience in the past, and he combined several of the kitchen knives he used most often.

Although Qin Yu rarely makes kitchen knives, his years of experience have made him see at a glance the special features of Hodge's kitchen knife.

After determining the shape of the blade, Qin Yu took out two cylindrical hand molds from the box and handed them to Sally El. The most important thing about customizing a kitchen knife for people is to make the chef feel comfortable holding the knife, so the making of the handle is extremely important.

This takes into account not only the length of the fingers, habits, but also the strength of the eater, which is a great test of the grinder's experience.

Sally El and Hodge held the hand model according to Qin Yu's guidance in the normal posture of holding a knife, and soon their respective grips were recorded by the hand model.

Qin Yu took the notebook to write, draw and draw, and finally determined all the data.

After the preparations were completed, Qin Yu began to take samples from the steel ingots brought by Lin Su to study the specific properties of this material in order to make adjustments. At this point, however, he ran into a problem.

Whether it is cutting with a chainsaw or high-tech such as waterjet and plasma cutting, there is no way to leave a trace on the ingot.

With such a hard material, Qin Yu really has never seen it in his life.

Seeing Qin Yu deflated, Hodge and the others remembered the picture of Lin Su cutting steel ingots from that giant iron lump yesterday. Originally, Hodge and the others thought that the iron lump was just ordinary steel, but they didn't expect that they and the others had tried their best to leave a trace on it. In the end, it was Lin Su who laboriously cut off such a large piece of steel ingot with a hand knife.

At this time, Lin Su knew that he was going to take action again. He stepped forward and motioned for Qin Yu to stand aside, then took a deep breath and slashed at the steel ingot. With a bang, Lin Su cut off a fist-sized corner from the steel ingot.

Qin Yu's gaze at Lin Su completely changed, and the metal that even the water knife couldn't destroy was split casually, is this still a person?

A ridiculous thought rose in Qin Yu's heart, this guy's body is the best sword casting material!

In terms of physical strength alone, Lin Su was indeed much stronger than the beasts of the same level.

Although Lin Su usually likes to use the energy of nothing to attack, his strong body is his most terrifying weapon. Since he had just cultivated, Lin Su's physical strength had grown much faster than that of the Three Tigers, and it had reached an extremely terrifying level after years of accumulation.

After getting the sample, Qin Yu directly put the steel into the furnace to heat it. However, after calcination for nearly fifteen minutes, the steel still showed no signs of discoloration.

"What the hell. Qin Yu felt that everything was not going well today. You must know that the equipment here is specially customized for forging high-temperature resistant materials, and ordinary steel bars will be burned red into a machinable state after one minute.

After another fifteen minutes, the steel barely turned fiery red.

Qin Yu didn't delay, picked up the steel with iron tongs and put it on the anvil and began to beat. However, even in the red-hot state, the hardness of this steel is not comparable to ordinary steel, and Qin Yu's hammer has become potholes after a few blows.

Seeing the scrapped hammer, Qin Yu actually looked up to the sky and laughed: "Hahaha...... I kind of understood today, what the world's number one grinder is, it's all false. It's sad that I don't have enough ability, and I can't deal with it even if I find the materials. ”

Lin Su stared at Qin Yu tightly, for fear that something would go wrong under his mood swings. In that case, Sally El's kitchen knife will really be in vain.

"I'm sorry, several, but I may not be able to complete your commission. After laughing, Qin Yu said with a disappointed face.

"Master, don't say that, the reason why you failed just now is just a problem with the tool. Lin Su hurriedly comforted him. "Wait a minute, I'll help you get a set of the right tools. ”

When preparing the materials before, he completely forgot about the problem of tools, which was Lin Su's mistake. Luckily he brought enough steel, otherwise he would have had to make another trip. There was only another steel cloud that could forge the steel cloud, and Lin Su quickly chopped it on the steel ingots he brought.

A rectangular steel ingot is used as an anvil, and a square steel ingot is made into a hammer, and a simple but practical set of tools is complete. With the addition of new tools, the forging can finally go smoothly.

It took most of the day, and the fist-sized piece of steel just now was beaten into a two-millimeter-thick piece of iron by Qin Yu. He took the piece of iron into another studio and tested it, and finally a satisfied smile appeared on his face.

Lin Su cut a palm-sized piece from the remaining steel ingots and began the formal forging work.

Heating, hammering, heating, hammering, this process is constantly repeated, and the steel block in Qin Yu's hand is getting smaller and smaller. The steel cloud also contained a large number of impurities in the process of formation, and those impurities combined with the real fog to form the steel cloud that Lin Su saw.

The quality of the steel is greatly improved by constantly hammering the impurities removed.
