Traveling through Great Qin: Father Qin Shihuang!

"You really have?"

Hearing this, Ying Zheng became excited.

Why is Zhao Che like a treasure chest, he can take out all kinds of weird things, how much is he hiding?

"Actually, it's not a rare thing, it's just a gadget, but it does save a lot of effort when building a house."

Zhao Che went back to the small room above the vegetable patch in his backyard. After searching for a long time, he took out a pack of iron objects wrapped in paper.

"Just this thing, can it save the effort of building a house?"

"Open it and see it!"

Zhao Che casually pointed, and Ying Zheng opened the paper bag, revealing the contents inside.

"Is this... a needle?"

"Have you ever seen such a thick needle?"

Zhao Che had no choice but to take out this nail that was rewarded by the system.

"Then what is this?"

Ying Zheng took a steel nail and looked at it over and over for a long time, but he didn't know what it was for.

"Didn't I say that this thing is used to build houses?"

"How is this thing built?"

Faced with Ying Zheng's doubts, Zhao Che did not hide it, and explained it to him.

"This object is called a steel nail, and its function is actually very simple. It is used to replace the mortise and tenon structure required for building a house."

"Tenon?"

Ying Zheng was a little moved. At first glance, it seemed that the steel nail was not very eye-catching.

But if it can replace the mortise and tenon structure, the effect will be extraordinary.

Most of the ancient buildings are made of mortise and tenon structure.

But the method of tenon and tenon is also very difficult to learn. Only craftsmen who have been immersed in this way for many years can make that kind of tight and strong tenon and tenon.

Moreover, the production of the mortise and tenon structure is also very time-consuming, and the accuracy is extremely strict. If it is slightly worse, it may cause the entire building to collapse.

If steel nails can completely replace the mortise and tenon structure, this will be another major reform in architecture.

In the future, craftsmen no longer need to spend time and effort making and researching various mortise and tenon joints, but only need to use steel nails of different lengths to fix each structure.

"Che'er, I'm really curious as a father. Where did you get these magical objects? Each of them can completely change the foundation of an industry."

Holding those steel nails, Ying Zheng sighed deeply as if he had found a treasure.

"It's all small things, not worth mentioning!"

Zhao Che waved his hand and said very modestly.

"Hahaha, Che'er, you don't need to be humble. This seemingly inconspicuous steel nail is a life-saving tool for the heads of Guizhou in South County. With this thing, their speed of building houses can be improved a lot. It can save a lot of manpower, maybe before winter, at least a lot of houses can be built to keep out the cold!"

"As long as it works!"

Zhao Che scratched his head. The heads of Guizhou in Nanjun played a vital role in his future rebellion against Qin. Naturally, he had to do his best to reduce their damage.

"Good boy, it's important. I have to go back as soon as possible and arrange for people to start producing the steel nails. I won't keep any more!"

Ying Zheng signaled Meng Yi to put away the bag of steel nails, and then he bid farewell.

"Father in that line, you go slowly, I won't send you off!"

……

Ying Zheng had just had a few glasses of wine, but now he was a little tipsy, his face was flushed, and he didn't know whether he was drunk or excited.

"Meng Qing, do you think Che'er was specially sent here to help the widow because God favored me, Daqin?"

On the carriage, Ying Zheng was extremely excited.

Every time they encountered a problem and were helpless, as long as they came to Zhao Che, it became a small problem that could be solved easily.

Zhao Che seemed to be omnipotent, and a thing he took out at random caused a change like a major earthquake to the entire Great Qin.

It's not that Yingzheng has never seen a genius. Lu Buwei's disciple Gan Luo, at the age of 12, has the ability to worship the prime minister.

Including himself, he ascended to the throne at the age of 13 and conscripted himself at the age of 21. It took ten years to unify the six countries.

But with Ying Zheng's pride, he had to admit that compared with Zhao Che, he seemed to be far behind.

Generally speaking, people who are exceptionally good at a certain aspect are called geniuses.

And there are many aspects that are particularly powerful, and people call them evildoers.

But Zhao Che, he is no longer talking about which aspect he is good at, but which aspect he is not good at?
Wenzhiwugong, art of war and strategy.

Zhao Che is proficient in everything from governing the country and raising troops to farming and building houses, and his achievements directly far exceed the concept of the era of Great Qin.

Then what should Zhao Che be called?Only immortals who descended to earth have such abilities.

"Your Majesty, no matter how powerful your son is, he is still your son. If you can give birth to such a powerful son, you should be the one who is so powerful!"

Meng Yi patted his ass flatteringly, not only praised Zhao Che, but also praised Ying Zheng incidentally.

Sure enough, Ying Zheng couldn't help laughing when he heard this.

"That's right, no matter how powerful Che'er is, isn't he still the son of a widow? With Che'er in my Great Qin, I will live forever!"

Getting drunk, Ying Zheng also temporarily lost his previous composure, said something very proudly, and then fell into a deep sleep.

……

"Your Majesty, return to the palace!"

When Meng Yi woke up Ying Zheng, they had already arrived at Xianyang Palace.

Ying Zheng squinted for a while, most of the alcohol was gone, and with Meng Yi's support, he returned to the hall.

"Mengqing, the production of these steel nails is relatively simple, and ordinary craftsmen can also learn to imitate them. After you go back, immediately send someone to gather the craftsmen and ask them to make a batch as soon as possible and send them to Nanjun for building houses."

"Here!"

Yingzheng got the order and was about to leave with steel nails.

"Master Shangqing!"

As soon as he arrived at the gate of the hall, Meng Yi met Zhao Shu who also came to report.

"It turns out that it is Zhi Su Nei Shi, His Majesty is in the palace, go in and report!"

Meng Yi greeted casually.

"Lord Shangqing, you and His Majesty went to Jingshui this time and met Mr. Che, did the problem be solved?"

"My lord is omnipotent. For the things that troubled us, you just took out one thing and solved the problem."

"Oh? What?"

"It is this thing, called the steel nail!"

Meng Yi took out a steel nail from his pocket and put it in front of Zhao Shu.

"So it's this one. I actually forgot. When the young master built a house, he took it out. It's much easier to use than the mortise and tenon structure."

"Hahaha, yes, with this steel nail, the reconstruction work in Nanjun can save a lot of manpower and time. The head of Guizhou in Nanjun is blessed!"
