Wang Wu looked at the back of Li Zheng leaving, and unconsciously felt a little more troubled in his heart.

After returning to Jingyang, Li Zheng went to the fields next to the horse circle to work and watched the peppers and sunflowers grow very well.

Looking at the huge flower plate of sunflowers, there will be melon seeds to eat in a few days.

After pulling out the weeds in the field, Li Zheng sat by the ridge for a while, watching the scenery around the horse circle and resting.

Li Yifu came with a silent vomit, "County Marquis, he's back." ”

Silently and respectfully, he said: "The county marquis, I contacted a few Western Turks in Chang'an, and now I have become one with them. ”

"Good." Li Zheng nodded.

Mo vomited and bowed down again and said: "Please also ask the county marquis to give you some more money, so that you can go to the Western Turks for a while." ”

"You still want money?" Li Yifu immediately shouted.

Mo Ge explained: "Without money, it is difficult to get along with the nobles of the Western Turks. ”

Li Zheng smiled and said, "How much do you want this time?" ”

Mo vomited and hesitated and said, "It's the same as last time." ”

"I'll give you ten times, but you must take care of it for me." Li Zheng said to him.

"The villain will live up to the trust of the county." Mo vomited and hurriedly bowed down and said.

Li Yifu went to withdraw the money with silent vomiting, and when the others left with the money, they were very curious.

When he came to the horse circle again, and saw that Li Zheng was playing Tai Chi, Li Yifu couldn't help but ask: "County Marquis, why did you give him so much money." ”

Li Zheng slowly made a move and said, "Are you confused? Before the matter was done, he came to ask for money first. ”

Li Yifu whispered: "I'm just worried that this person has other plans." ”

"If you feel confused, it is better to play Tai Chi with me, which is good for your body and mind."

Li Yifu stood behind Li Zheng and followed Li Zheng's movements and played Tai Chi.

Li Zheng made a move and said, "Do you think it's very unpractical to let a Turk do things?" ”

Li Yifu replied in a low voice: "I just feel that this silent vomit is not trustworthy, and he is an outsider." ”

Li Zheng said slowly and leisurely playing Tai Chi: "There will be no burden for outsiders to use it, if this silent vomit comes to me again to ask for money, I am relieved a lot, which shows that he is really doing something." ”

"And what if he takes the money and runs away?"

Li Zheng took the invitation and stood still, "He is a shrewd Turkic merchant, if he runs away, I will only lose some money, it's a big deal to change someone, Mo Zhi knows very well in his heart whether these silver cakes in his hand are important or the errand I gave him is important." ”

"As long as he wants to make more money, he must follow me, if he doesn't follow me, this money may bring him death or will always run out one day, depending on whether he wants the immediate or long-term."

After speaking, Li Zheng sat down again, drank tea, held the heavenly creation, and then looked at it, "Besides, if there is a change in the future, we need a scapegoat, and I couldn't be better to let this Turkic merchant be the scapegoat, are you right?" ”

Li Yifu nodded with a clear face, "The good and bad have all been thought of by the county marquis, and they are being stupid." ”

Li Zheng nodded and said, "Sycophant kung fu is still a little worse than Xu Jingzong, and you need to learn more." ”

Li Yifu nodded again and again.

"Don't delay the construction of roads." Li Zheng turned the page and said.

"Just keep an eye on it." Li Yifu left in a hurry.

Tiangong Kaiwu only has a few pages on the technology of steelmaking, and only introduces some processes.

I don't know if it will work, Li Zheng turned the page again to improve the level of steelmaking technology.

The system of crops is still in the second stage, and I don't know if there will be cotton, oak and other plants in the third stage of crops.

First of all, the level of steelmaking is improved, and in the era of no rubber, cork can be used instead of rubber to make tires, and the hardness and structure of the steel frame determine how much weight can be carried.

Li Zheng rubbed his eyes, he had to be short-sighted if he looked at it like this.

In ancient times, myopia was a very serious problem.

Relaxing his eyes, Li Zheng was still thinking about the manufacture of tricycles in his heart.

The tricycle is a very landmark means of transport.

It can carry people and goods, and the earliest tricycle to say tricycle actually existed in the Qin and Han dynasties.

However, it was not until the beginning of the 20th century that pedal tricycles became popular.

Look at your system panel again: take some eye drops from the system pharmacy and put them in your eyes to relax your eyes.

Di Renjie, Da Niu and Pei Xingjian have been studying the role of force these days.

Friction, attraction, pressure, and more.

These are very simple mechanics, Da Niu looked at the rolling speed of several wooden wheels in front of him and recorded some data.

This is an experiment, Di Renjie and Da Niu are thinking about how to make a car travel faster.

This is a simple mechanical experiment, taking into account the weight, friction, and resistance.

There are many experiments related to Newtonian mechanics, and Di Renjie and Da Niu are very talented, and they can always draw conclusions quickly in several experiments.

Shangguan Yi has been observing these children these days, and their growth is in sight.

On weekdays, Li Zheng just clicks a few words, and these children can learn quickly.

Although these knowledge Shangguan Yi did not take to heart, these children grew up too fast.

Sometimes, even Li Chunfeng and Yan Liben had to ask these children about physics.

Shangguan Yi sighed, "What kind of monster did Li Zheng teach?" ”

In the school field of Chang'an Jin Wuwei, Yan Liben wasted a lot of effort to make the Ministry of Industry imitate ten compound bows.

Li Shimin asked the old generals of Chang'an to give it a try.

After watching the generals test it several times, Li Shimin had a smile on his face.

The generals also had smiles on their faces, for whom the usefulness of this compound bow was not trivial.

Cheng Yanjin hurriedly said to Li Shimin: "Your Majesty, this compound bow should be arranged for the leading guards of the last general, the responsibility of leading the military guards, it is not easy to protect Chang'an, with this kind of compound bow, you can better capture the gangsters in Chang'an in the future." ”

Niu Jinda hurriedly said: "Old Cheng, who doesn't know that your leading guards are gags all day long, and you are just catching some small thieves and asking for some compound bows." ”

Li Xiaogong also said: "If you want to give, you must first give it to Jin Wuwei, who is in charge of the guards of the imperial city." ”

Cheng Yanjin said unhappily: "Li Xiaogong, you said that you are a secretary of the Ministry of Rites, and you are in charge of Jin Wuwei. ”

Li Xiaogong smiled coldly, "Who doesn't know that you Cheng Biting Jin has a compound bow just to have a good time." ”

"Alright, don't make any noise." Li Shimin opened his mouth and said: "First send it to Wei Chigong in the Hexi Corridor, and give 100,000 compound bows to the border army." ”

Cheng Yanjin didn't want to say anything more.

Li Shimin glanced at the generals and said, "Each of these ten compound bows will be given to you." ”

"Thank you, Your Majesty!"

A group of generals saluted.
