"Director Zhang, don't worry about studying gears, and the machine drives more than just gears, as well as chains and belts. Your biggest task at the moment is to build the Weihe Bridge..." Chen Xu pulled Zhang Cang off the carriage and said with a smile.

Zhang Cang came back to his senses, looked at the lively and prosperous scenes on both sides of the Wei River, nodded and clenched his beard and said, "Don't worry, Marquis, Cang will not delay the construction of the bridge, but Cang is very interested in the construction of gears. Marquis, do you think you can really create a car that can run by yourself without pulling a cow and horse..."

"Okay, OK, Dean Zhang must not give up on his food because of choking. We will discuss these things when we have free time. I will leave first if I have something to do!"

Chen Xu knew that Zhang Cang was a math fan and an engineering fanatic. He was particularly interested in theories such as geometric parabola. If you want to study more precise gears and even chain transmission systems, you must have good geometry, because all gears are cut in circles.

But the current situation of Daqin does not take priority over inventions, even if it invents tanks, planes and cannons, it is useless. The crux of Daqin is the strategy of governing the country, how to liberate farmers, craftsmen and merchants, so as to make these three bottom-level people rejuvenate and energetic, and be able to greatly improve their living conditions through their own labor and gain the political status they should have.

When the exploiting classes such as gentry and aristocrats cannot be eliminated, we must create a living environment that can be eaten and fed without worries to the lower class as much as possible, so as to calm the huge domestic conflicts.

Therefore, Chen Xu has never been particularly concerned about the development of the Academy of Sciences. When he came to Xianyang, he had two purposes for the establishment of the Academy of Sciences.

The first is to create a completely different working environment for yourself, which is completely different from that of the civil and military officials of the court, so as to reflect your unique value. Summoning a large number of craftsmen is just slowly applying some of the things he designed. In fact, so far, all the inventions of the Academy of Sciences have been completed by Chen Xu alone.

The second is to use the Academy of Sciences as a cover to avoid head-on conflicts with the disciples of the Legal family and the bosses in the court. With the Academy of Sciences as an excuse, Chen Xu could not go to the court to discuss politics, so that all the civil and military officials in the court believed that Chen Xu was just a fairy disciple like a idle cloud and wild crane were unwilling to get involved in the government affairs, which would increase the distance and create a more mysterious feeling.

Most of Chen Xu's court visits were invited by the emperor. If he took the initiative to go to court, there would be something to report. Therefore, Chen Xu always spoke in the court with great weight, aimlessness, and did less and more. This is what Chen Xu gave everyone, and he was basically helping the emperor solve problems. Therefore, the emperor's request for Chen Xu almost always was accurate.

However, seven or eight days have passed in the blink of an eye. When the court heard that it was noisy every day, the emperor also summoned the princes and princes to the palace to discuss, but there was still no result.

It seems that this kind of reform that touches the core interests of the exploiting classes such as the ministers and nobles is indeed full of difficulties.

By improving the identity of merchants and abolishing the laws of suppressing merchants in the business laws, merchants can obtain the status of civilians and can do business freely. Without the suppression of laws, merchants are all rich people, and will soon prosper to form an emerging class, and may even compete with the nobles.

This is the concern of most nobles.

Therefore, this matter is completely different from the reform of the court system such as the three provinces and six ministries.

The abolition of the Three Dukes and Nine Ministers and the restructuring of the Three Provinces and Six Ministry did not touch any interests of the bureaucratic and aristocratic groups, at most it was the reallocation of interests.

But the abolition of commercial laws has touched on the fundamental problem of this social system.

Moreover, Chen Xu's meaning is not just to loosen the ties for merchants. Once this opening is opened, there will inevitably be more actions to liberate craftsmen, farmers, and even slaves... Although this possibility is relatively small, it has to arouse the vigilance of all gentry and nobles.

But no matter what, the identity of Qinghehou cannot be easily offended. The people who offended him basically ended up miserably. Even the three royal tribes of Zhao Gao were deposed as slaves and sent to Shu.

Although this punishment cannot satisfy Chen Xu, in fact, for the Great Qin royal family, this is already the heaviest punishment. The previous Great Qin royal family that was killed was Chang'an Jun Cheng Chuang.

Cheng Qi was killed because he truly rebelled against Qin and surrendered to Zhao, so he was finally killed. Zhao Gao was actually far from the point of treason...

As the carriage entered the city, Chen Xu sat in the shaking carriage, looking at the noisy scenes of crowds on the street and the buses that occasionally galloped across the street, but he was repeatedly thinking about the things he was discussing.

"Mr. Marquis, a postman just sent a letter!" Chen Xu had just returned to the Qinghe Marquis' Mansion, and the manager came in to report with a bamboo tube covered with a mud mark.

"Where did it come from?" Chen Xu took the letter.

"The postman said it was sent from Sishui County!"

"Okay, go!" Chen Xu sat down on the chair in the study, and after the manager left, he smashed the sealing mud and opened the bamboo tube, poured out a few pieces of hemp pulp paper rolled together from it.

Chen Xu seemed to be in a calm mood, but in fact his heart was pounding and he couldn't stop.

The letter from Sishui County must be Jiangbeiting, and there should be news from Liu Bang.

Liu Bang, he was destined to become the nemesis of the Qin Dynasty, but what would happen if he met himself?

If it were him, how should he deal with it? Will he be punished by God if he killed such a figure who should have become an emperor and forged the Han spirit?

Chen Xu opened a few pieces of hemp pulp paper with a slight trembling finger. The neat handwriting written by Jiang Beiting himself was touching.

"The Jiang family's Northern Pavilion has been serving the Marquis of Qinghe in Beiting. It has been more than a month since Beiting went to Pei County to perform its duties. He kept in mind the marquis' instructions, so he secretly sent someone to find out whereabouts of Liu Ji. As the Marquis said, it was no different. Liu Ji was born at the age of 38. In the winter of the 59th year of King Nan of Zhou, he was born in Feng County. He was four brothers. When he was young, he studied in Ma Wei in Feng County and studied at Magong Academy. He had a friend born in the same year. He was a little older and did not like to work or pay attention to the details..."

"Liu Ji had ambitions. When he was young, he traveled to Daliang to join Xinlingjun. After he failed, he joined Xinlingjun's disciple Zhang Er as a guest. The Wei Kingdom was destroyed and Zhang Er was wanted. All the guests were dispersed. Liu Ji returned to his ancestral land, Pei County, married his wife, Lu Zhi, father-in-law Lu Wen, from Shan County. He was in trouble with Pei County because he had hatred in his hometown and lived in his life. He was close friends with the former Pei County Magistrate Xu Jing. Therefore, after Liu Ji returned to his hometown, he was very cared for by Xu Jing and was appointed as the head of the Sishui Township. Liu Ji usually drank and gambled money, and was familiar with many officials such as Cao Shen and Xiao Hezhe in Pei County..."

Jiang Beiting did not dare to be careless about the things arranged by Chen Xu, so he put in a lot of effort. He secretly inspected for more than a month and wrote six pages of hemp pulp and paper about Liu Bang's life experience.

These contents are similar to the vague historical records that Chen Xu knew. Even his wife was named Lu Zhi. He was really the head of the Sishui Township. He didn't like to work but drank and gambled all day long. He also had a good relationship with the county officials in Pei County. Cao, Shen and Xiao He and the other two were not missing.

In other words, after I traveled through time, I did not change the existence of any historical figures.

"In order to better control Liu Ji, Beiting promoted him to prison guard and secretly arranged for family servants to monitor him at all times, so that he would not be allowed to leave the surveillance. Regarding Liu Ji's affairs, we will also write letters to the Marquis in the future. If the Marquis has other instructions, we can also arrange letters to inform him, and Beiting will deal with it properly..."

After reading the last page, Chen Xu put down the letter and sat in the study room silently for a long time, took out paper and pen to write a reply, saying that the letter had been received, expressed his gratitude to Jiang Beiting, and told him to properly place Liu Bang, and that he would go to Pei County in person after he had arranged it.

After the letter was written, sealed with a bamboo tube, stamped with a seal with mud and stamped with your own seal, and then dried in the kitchen and arranged to send it to the inn for the soldiers who conveyed the letter to Peixian and handed it over to Jiangbeiting.

Since Liu Bang and the historical descriptions are undoubtedly, Xiang Yu and Xiang Liang will definitely appear, and they will probably receive a letter from Jiang Heng, the governor of Kuaiji County, in the near future.

A day passed by, and it was Shen Shi in a blink of an eye.

A school bus from the Women's College came and stopped at the gate of the Qinghe Marquis' Mansion. The guard and the servant rushed forward with a few maids. The car door opened. Yu Ji and Xing'er two little girls were carrying small schoolbags and couldn't wait to jump out of the carriage. They were surrounded by several maids. Some people helped to get the schoolbags and feed snacks, which was simply the standard life of a noble lady.

Shui Qingrou got out of the car and said thank you to the groom. A few little girls poked out of the car window, waved to the outside of the car. Amid the teacher's goodbye, the school bus left and soon disappeared on the street.

"Squeak~" The door of the study was pushed open. After washing up, water from the house dress was changed and gently pushed the door in. Looking at Chen Xu, who was sitting in front of the very dark desk, he quickly picked up a box of matches and lit the candlesticks on the desk.

"My wife is back!" Chen Xu came to his senses from his thoughts, reached out and held Shui Qingru's hand and hugged him on his lap.

"What are you thinking about, husband?" Shui Qingrou asked softly.

"I received a letter from Jiangbeiting today and found Liu Bang in Pei County. I thought about it for a long time but didn't know how to deal with him!" Chen Xu handed the letter on the desk to Shui Qingrou with a melancholy expression on his face.

"My husband, don't worry. You are now the Marquis of Qinghe, and Your Majesty has also been named Marquis of Jingyang. These marquises have never had any status since ancient times. It can be seen that Your Majesty respects his husband very much. Liu Bang is just a commoner. It is easy for your husband to deal with him, and there is no need to worry about it..."
