Minutes and seconds passed. Rong Bai's hands were steady and lumpy, and the two people who were watching from the side began to sweat.

The biggest difference between these tools and their previous known assembly methods is that the internal structure of these things is far more complex than the external ones. Moreover, the internal structure is very important, and if something goes wrong, it is a catastrophe. The last time there was an accident, it was caused by the fifth prince connecting the fire wire and the neutral wire wrongly.

"That's it. Rong Bai showed the things he had assembled to the two of them.

"Is this a trick?" Chen Huizu pointed to the thing in Rong Bai's hand. It was about half a man tall and black throughout. In the middle there is a black iron rod, and on the other side, there is a fastener.

"I've used this a lot since then, so it's not surprising that you don't know it. Rong Bai patted it with a smile: "With it, it will be much easier to make parts in the future." ”

Rong Bai was quite satisfied with the lathe in front of him. Of course, this thing can't be compared with the mechanical arm treasured by Rong Bai in the last days, but in this era, it is already the pinnacle of science and technology. Moreover, with this lathe, the construction time can be saved. You must know that the quality requirements of the tools that Rongbai is doing now do not need to reach the level of Rongbai forging, and it is better to use a lathe instead of spending time forging parts by yourself.

"Rong Bai, this palace wants to see how you use this tool. "The Fifth Prince is very interested in this tool.

The lathe is different from other tools, and the tools made before are not large, and they can basically be carried with one hand.

However, the fifth prince looked at the thing in front of him, and said whether he could pick it up, and even if he picked it up, he couldn't use it.

"Then you wait a minute. Rong Bai strode to his side and took a design drawing, and a palm-sized piece of metal. The design drawings were left by Xiaoheng, and the metal blocks were provided by Linjiang Group. Holding the metal block, Rong Bai bent down, took three wires from the large box under the table, and connected them to the lathe.

I pressed the switch and debugged it.

After confirming that everything is correct, Rong Bai installs the metal block on the fixture, selects the tool, and starts the demonstration.

The fifth prince knew that Rong Bai's tools were excellent tools that could save a lot of working time. However, saving time to such an extent, the five princes never thought of it. Seeing that the corner was square, not a sharp thing, but it could cut the metal block layer by layer, and soon, the metal block on Rong Bai's hand became a strange shape.

Compare the design drawings again, and they are exactly what they look like on the design drawings.

The hands of the five princes were trembling.

This thing is too much beyond his cognition. You know, even if you ask the best blacksmith to do these parts on the blueprint, it will take a lot of time. However, how long does it take for a part to be in Rong Bai's hands?

The lathe stopped, Rong Bai reached out and took out the parts, compared the design drawings, visually inspected it, and made sure that it was qualified, before putting it aside. With the other hand, the turning tool is removed.

"But the blade is broken?" Chen Huizu asked curiously.

"It's not. Rong Bai shook his head.

The entire lathe was built by Rong Bai himself. A weapon of comparable quality to Rong Bai, how can it be so easy to go wrong. Rong Bai handed the knife edge to the two of them: "This is a turning knife, you will all use it in the future." There are many types of turning tools, and I only make a dozen of them at the moment, and I will be forging turning tools for the next period of time. ”

Speaking of this, Rong Bai paused and pointed to the box not far away: "So, those blueprints will be handed over to you." ”

The blueprints in the box?

Chen Huizu didn't feel anything, but the five princes were crazy. How many blueprints were in that box, could he not know? Do all those things have to be done with these knives? This must be crazy. However, this lathe is really eye-catching.

The fifth prince has been here for a long time, and everything here has a fatal attraction to him. However, the thing that made him blush the most was the thermal power generation system in half of Rong Bai's room, and the other was the lathe in front of him. You must know that in this era, the most restrictive industrial development is the extremely low labor efficiency.

Once this thing is promoted, you can imagine what Dayong will develop.

After Rong Bai handed over the lathe to the two of them, she went back to the half of the workshop where she had stayed. The furnace in the workshop, as long as there are people, is burning. Rong Bai took several of the same metal and walked to the stove.

The two people outside are studying to make parts, and Rong Bai is also going to make something, but what is being done now is not a turning tool, but Rong Bai's own equipment.

Warriors of the last days do not just carry their main weapons into battle. Rong Bai's only weapon now is the long knife he made before. Rong Bai's long knife had been hidden in the box and was not used at all. That guy is just too conspicuous. What Rong Bai has to do now is to prepare some inconspicuous weapons for himself and Hengqing.

The sound of tinkling and ding, calmly entered, and sounded until dark.

Even for lunch, Rong Bai didn't come out to eat.

The two men studied the lathe for a day, and without Rong Bai giving instructions, the fifth prince studied the use of this thing.

This thing is really easy to use, but ordinary people will never be able to manipulate the lathe to make the entire part like Rong Bai, who can control the lathe with a few glances at the design. The Fifth Prince used dozens of metal blocks and a day to make a part, and also found a way to use this thing.

This method is the most profound for Chen Huizu.

Because it's all data-dependent, it's all mathematical.

The sentence of the fifth prince, "the level of arithmetic in the nine chapters", is really a basic level in Chen Huizu's eyes now. Chen Huizu, who originally thought that he was strong in mathematics, found for the first time that he was really too far away from the level he imagined.

"Rong Niangzi, can you really calculate these data at a glance?"

When the first part was successfully made, Chen Huizu carefully studied the calculation process of the five princes page by page, such a complex calculation process could not be inferred without a cup of tea, and Rong Bai obviously speculated for a shorter time, and it was impossible to have a cup of tea.

"Experience. The fifth prince rubbed his temples.

The calculation of a part almost made him collapse, and now what is in front of him is the design drawing of a box, which means that there is a box of parts to do, and he has to calculate when. Now, the five princes are very grateful, and Rong Bai still kidnapped the unlucky guy in front of him.

As long as this person is trained, he can't say that he can really be freed from countless calculations.

The reddish metal block submerged in the water, and after a string of white mist, the black weapon revealed its hideous appearance.
