The steel balls were picked up casually on the scrap table, but now they were handed over to Mr. Liu, but they were not what they were originally looking.

The steel ball with a diameter of ten millimeters has been processed by Guo Tailai with a nanorobot just now. The outline is still a steel ball, but some changes have occurred inside and outside.

There were three more holes on the surface, and the inside became three layers, one layer after another, but the inside would not fall outside. This kind of ball has a name in the art market, called ghost worker balls, or ball sets, which are usually carved in ivory. In 1992, domestic experts were able to achieve three-layer ghost worker balls of the same size as the layer ghost worker ball collected by Emperor Jiajing.

Tailai's this one can also be called a ghost worker ball, but it is only three layers, and the carving is not that fine, pure mirror spherical, smooth, but the material is steel ball. Time is limited, Guo Tailai only made three layers in a hurry. Of course, time allows for multiple layers, but that is a bit too exaggerated.

Of course, I wouldn't think that Guo Tailai would give him an ordinary steel ball. I felt something different when I took it. When I looked carefully, I immediately understood what it was. I couldn't help but become interested, so I took a thin needle and checked how many layers Guo Tailai had made.

Although it is only three layers, Mr. Liu doesn’t look dissatisfied at all. This is a steel ball. What kind of craft is it to be taken from outside?

Mr. Liu checked more than a few layers, but also the sphericality, processing accuracy, and roughness of the inner layer. He looked at it one by one, and Mr. Liu was finally satisfied. As a disciple, his skills are getting more and more sophisticated.

In fact, the places that Mr. Liu had not checked, such as the inner layer of the sphere, were actually the same as the outer layer, and were all perfectly round and mirrored. However, Mr. Liu didn't even know what tools to use for checking these places.

"What are you looking for a shoe-making expert?" Mr. Liu finally asked Guo Tailai's purpose of finding a master, which shows that he has recognized Guo Tailai's craftsmanship.

"Make a few pairs of combat boots." Guo Tailai replied: "The current Liberation Shoes are actually not suitable for certain combat occasions. I need to make a few pairs of military boots that can provide more protection for soldiers."

Battle boots?" Old Liu was stunned, and then suddenly realized: "So that's the case. OK, I'll go find my old friend and see if he is interested."

Afterwards, Mr. Liu took Guo Tailai away from the fitter workshop and walked directly outside the south gate. Guo Tailai followed the side honestly, chatting while walking. After leaving the south gate, Mr. Liu asked Guo Tailai to take a yellow van directly, talked about his destination, and drove directly over with the yellow face.

After getting out of the car, there was an alley area. Mr. Liu got into one alley and came out from the other end. He found a small shoe repair stall at the entrance of an alley that was more than ten meters away from a major intersection.

A very simple shoe repair stall, a hand-cranked scaffold, a pile of tools such as pliers, scissors, glue, and some leather soles. There was an old man wearing glasses sitting behind him. There was no customer, and the old man was squinting his eyes and listening to the radio, crossing his legs, and his toes were still stumbled with the drum beats of Peking Opera inside.

Old Li, there is a living here!" Old Liu walked over and looked at the scene, smiling happily. He sat directly on the stool for the guests and greeted the old man opposite.

When he opened his head and saw that it was Mr. Liu, he immediately laughed: "Why are you free to come to see me?"

"It's my apprentice who is looking for you." Old Liu smiled and introduced to the old man: "Old Li, this is my apprentice, just call him fat. Fatty, this is Old Li."

Hello, Mr. Li! "Guo Tailai dared to be as casual as Mr. Liu, so he quickly bowed and said hello."

What are you looking for me?" With Mr. Liu, and Guo Tailai was so polite, Mr. Li asked kindly.

I want to find you to make a few pairs of shoes." Guo Tailai then honestly told his thoughts. Anyway, it was just combat boots, not something to keep in secret. Guo Tai said that he had no psychological burden.

For an old man who can make space boots, um, even if he hasn't been in space, it is definitely of extremely high technical content. For an old man who can make this kind of boots, Guo Tai's combat boots are not difficult at all. Mr. Li patted his chest and promised that he could start making them immediately if he wanted to make them and prepare the materials.

Inside, the most technological content may be that the several layers of different materials on the sole are integrated in layers, ensuring elasticity and excellent protection. In other aspects, the leather and fabrics are well prepared, which is basically a hand-sewn material.

Of course, Guo Tailai prepared the materials. Guo Tailai knew what parameters required rubber, what parameters required Kevlar material, and lining. But Guo Tailai had to ask Mr. Li about what kind of skin to meet the requirements.

If you follow the consistent requirements of the army, defense must be preferred, so the thicker the skin, the better. But Guo Tailai knows the shortcomings of some military boots in later generations. Thickness is definitely one of the disadvantages, so of course it should be avoided. It must be sufficient protection and light and breathable, which is a bit higher.

Although Mr. Liu from Bian is not an expert in this field, he also made some suggestions in the use of certain materials.

It seems that I was back when I was working, and I was full of energy. No matter how the three of them are now at a small shoe repair stall in the alley, if someone who didn't know heard what they were talking about, would they think they were in the laboratory of which research institute?

After chatting until dark, Mr. Li took the two of them to have a meal at the dumpling shop at the alley mouth and then continued to chat. Guo Tailai also found some paper and drew out several combat boots in his future dream. Mr. Li discussed with the two and made a long list, and asked Guo Tailai to be responsible for collecting raw materials. Mr. Liu decided to go back and make him a set of shoes for Mr. Li as required.

The division of labor was clear, and the group talked until after ten o'clock in the evening. Guo Tailai and Mr. Liu first sent Mr. Li home with Mr. Li, who was in the alley, was very convenient. Then Guo Tailai sent Mr. Liu back to the downstairs of the school's family building, and then went home to rest.

The next morning, Guo Tailai arrived at the company and asked the business department to order separately according to the content of the list. Linings are very expensive, but as long as you are willing to spend money, you can still buy them. The leathers are the same, but there is one thing that doesn't work. Kevlar materials are now military products, and it may not be so convenient to order for a civilian company.
