Cheng Chumo rode for more than two hours, until this guy was too tired to ride.

The tricycle is still intact.

This time Li Zheng was a lot satisfied, and this time he also added brakes.

The brakes made by Tieda can only be used on the front wheels, and if you want to pull the brake pads of the rear tires, the toughness of the wire is enough to create it for the time being.

Today's craftsmanship is not good enough, so you have to design a cleats that run vertically from the front to the front wheels, and use levers to grip the rotation of the front wheels to achieve the brakes.

It is still difficult to reproduce the tricycle of later generations.

At least today's level of craftsmanship needs to be improved, and it has not reached that point.

Li Zheng handed over the tricycle to Da Niu, and then let Da Niu ride to pull the goods.

Seeing that the big cow put a lot of bellflower on the back of the tricycle, it was much easier to ride all the way.

The bellflower piles up taller than an adult man, and a ten-year-old child can ride and pull it away.

Yan Liben looked at his results and said with a satisfied face: "Maybe it's the so-called four or two thousand catties." ”

Li Zheng said: "This is knowledge. ”

Yan Liben saluted Li Zheng slightly and said, "Thanks to you Li Zheng, the old man knows that there are so many mysteries in the original craftsman. ”

"The fusion of craftsmanship and knowledge can make more things that benefit the world." Li Zheng said to Tie Daya: "Do you still feel sorry for Tie Liu? ”

Tie Da shook his head and smiled innocently, "Don't feel distressed." ”

Tie Er said: "In the past, the big brother who built weapons often didn't sleep well, and I didn't know how many people would be killed by the weapons he created. ”

"Guilt?"

Tie Da scratched the back of his head and smiled innocently.

Li Zheng said to Tie Da: "Just think of it as accumulating virtue, we will fight less weapons in the future, and build more things that can make money and make things convenient for the village, which can be regarded as peace of mind." ”

The Iron Ambassador nodded vigorously.

It's the hottest month of summer again, and the sun is shining.

Li Zheng was sitting in a short coat at the back of the house in the stable, hiding from the sun.

Li Tai picked up the cold water chilled with saltpeter and drank it, which made him feel a lot more comfortable.

"The case of the temple has not found any clues in Dali Temple so far." Li Tai poured a sip of water and said.

Li Zheng shook the folding fan in his hand disapprovingly, "Then Dali Temple will continue to investigate?" ”

Li Tai explained in a low voice: "It is estimated that it is unlikely that the case will be closed, but this case will become an unsolved case, in fact, there were many unsolved cases as early as when the imperial grandfather just ascended the throne, and these unsolved cases have not had a result until now." ”

Li Zheng smiled a little self-deprecatingly, "If you want to close the case, it depends on whether your father wants to investigate it." ”

Li Tai nodded and said, "You're right. ”

As long as Li Shimin wants to make a case an unsolved case, he is an unsolved case.

If Li Shimin wants to close the case, he will ask to the end.

For the emperor, many of his goals were to consider whether it was beneficial to him.

If it is a case, Li Shimin does not want people to know the reason, even if the result is investigated, Li Shimin will erase the matter and make it an unsolved case.

And this kind of thing is not very difficult for Li Shimin, it is just a very casual sentence.

Although he doesn't like this kind of autocracy, what Li Shimin wants to do has little to do with him.

The matter of compiling the geographical chronicles was placed in Jingyang, Li Tai was fine, and he was too lazy to go to Chang'an now.

All the things in Chang'an have been dug up, and Li Chengqian will cause disaster as much as he likes.

In the past, Li Tai had always been competing with Li Chengqian in secret.

Now that Li Tai has experienced this kind of relaxed and freehand life, he naturally doesn't want to get involved in those things in the court.

Li Tai continued: "Li Chunfeng has not been out of the customs for a long time since he entered the DPRK, and it is said that he is in retreat. ”

"Still researching?"

Li Tai nodded, "Many of the classics in the court were brought in by Li Chunfeng, and I remember that you provoked him to do this." ”

Li Zhengchang sighed and said, "Don't worry, this matter is very useful to your Li family." ”

Glancing at the scorching sun in the sky, Li Tai poured another sip of cold water.

Half a month has passed in the blink of an eye.

When Mo Ge came to Jingyang again, there were already three tricycles in the village.

Li Zheng also received a reply from the system.

System progress: 14,600 acres of territory, 19,300 people.

Reward for completing the mission: Crop Stage 3

New Mission: Population increased to 30,000.

Reward: Library Phase 3.

There are not many plant seeds in the three stages of crops, but they are all good things, there are cotton, oaks, and even strawberries, carrots and figs Before I finished reading the categories on the system, Xu Jingzong had already brought a silent gag.

Li Zheng put away his mind and said to Mo Zhi: "How are things going?" ”

Mo Yan took out two parchment rolls and said: "Back to the county marquis, the villain also went to contact the Tubo people, and several Tubo nobles also wanted to buy weapons from the county marquis. ”

Li Zheng picked up the parchment scroll of Tubo, on which were written crooked Tang characters.

"This is the nobles of Tubo who want to buy it? Isn't Songtsen Gampo to be bought? ”

"Yes, these nobles want to rebel against Songtsen Gampo, they think that Tibet should not wage war against the Western Turks, and they want a truce." Said silently.

Li Zheng put the parchment roll of Tubo aside, and said to Mo Zhi: "You give this parchment roll of the Tibetan nobles to Songtsan Gampo, it will be regarded as you selling him a favor, and you can do better business with him in the future." ”

"Whoa." Silent gagging nodded in agreement.

Li Zheng said: "Don't you ask me why I sold my own customers? ”

Mo vomited and lowered his head, "The villain just knows that once the war between Tubo and the Western Turks is suspended, the villain and the county will have no business to do, and the villain will be useless to the county marquis." ”

"Clever."

"The county marquis crosses the river, the villain is just some little cleverness, and the county marquis is the great wisdom."

Mo Yan continued: "In fact, the villain thinks that the affairs of these Tubo nobles do not need to be told to Songtsen Gampo, and the villain can help the county marquis eradicate them. ”

"Eradicate them? You're doing well in Western Turks and Tibet. ”

Mo Yan hurriedly took two steps back and bowed and said: "The villains are all dragging the blessings of the county marquis, the villains are rich and the nobles of the Western Turks appreciate them, there are many people who are willing to take refuge in the villains, if the county marquis is unhappy, the villains can dismiss them immediately." ”

"No, you don't." Li Zheng took a sip of tea and said, "The greater your power, the better, if you can control the Western Turkic royal court." ”

Silently vomit under the eyes, controlling the royal court of the Western Turks? It's crazy too.

"The villain has only 300 guards and 200 servants."

Li Zheng knocked on the stone table and thought for a moment, "You can do something bigger, I won't stop you, the more you mix between the two of them, the smoother my business will be." ”
