"Dean Zhang, there is no need to worry about studying gears, and there is not only one way to transmit the machine, but also chains and belts, etc., your biggest task at the moment is to build the Weihe Bridge......" Chen Xu said with a smile as he dragged Zhang Cang off the carriage.

Zhang Cang came back to his senses, looked at the lively and prosperous scene on both sides of the Wei River, nodded and stroked his beard and said: "Hou Ye, don't worry, Cang will not delay the construction of the bridge, but Cang is very interested in the structure of the gears, Hou Ye, do you think it is really possible to make a car that can run by itself without being pulled by a cow......

"Okay, okay, Dean Zhang, don't waste food because of choking, we'll discuss these when we have time, and I'll leave first if I have something to do!"

Chen Xu knew that Zhang Cang was a math fan, and he was also an engineering fanatic, and he was particularly interested in geometric parabola and other theories, if he wanted to study more precise gears or even chain transmission systems, he must have a good geometry, because all gears are cut out of circles.

But the current situation of Daqin is not a priority over invention and creation, even if the invention of tanks, planes and cannons is useless, the crux of Daqin at the moment is the strategy of governing the country, how to liberate the peasants, craftsmen and merchants, so that the three lowest people can be full of vitality and vitality, can greatly improve their living conditions through their own labor, and get the political status they deserve.

Under the circumstance that the exploiting classes such as the gentry and the aristocracy cannot be eliminated, it is necessary to create a living environment for the people at the bottom to be able to live without worrying about food and clothing, so as to calm down the huge contradictions in the country.

Therefore, Chen Xu has not been particularly concerned about the development of the Academy of Sciences, and when he first came to Xianyang, he asked for two purposes to form the Academy of Sciences.

The first is to create a completely different working environment for himself from the Manchu Dynasty civil and military ministers, in order to reflect his unique value, and gather a large number of craftsmen just to slowly apply some of the things he designed, in fact, so far, almost 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, in order to avoid head-on conflict with the disciples of the Legalists and the bigwigs above the court, with the Academy of Sciences as an excuse, Chen Xu can not go to the court to discuss politics, so that the civil and military forces of the Manchu Dynasty think that Chen Xu is an immortal disciple like an idle cloud and a wild crane is unwilling to get involved in the government, so as to increase the distance and produce a more mysterious feeling.

Most of Chen Xu's last court was invited by the emperor, if he took the initiative to go to the court, there would definitely be something to report, so Chen Xu was particularly weighty every time he spoke in the court, nothing was targeted, and he said less and did more, this is the impression that Chen Xu gave everyone, and he was basically helping the emperor solve the problem, so the emperor almost always approved Chen Xu's invitation.

However, seven or eight days have passed in the blink of an eye since this time to ask for the relaxation of the Shang Law, and I heard that the court is noisy every day, and the emperor has also summoned the princes and princes to the palace to discuss, but there is still no result.

It seems that this kind of reform, which touches the core interests of the exploiting classes such as the public secretaries and scholars, is indeed full of difficulties.

Improve the status of merchants and abolish the law that suppresses merchants in the commercial law, so that merchants can obtain the status of commoners and can do business freely, without the suppression of the law, plus the merchants are all rich people, and they will soon flourish to form a new class, and may even compete with the nobles of the noble clan.

This was the concern of most nobles.

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

The abolition of the three princes and nine secretaries and the restructuring of the three provinces and six ministries did not touch any interests of the bureaucratic and aristocratic clique, and at most it was just a redistribution of interests.

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

And Chen Xu's meaning is not just to loosen the shackles for merchants, once this opening is opened, there will inevitably be more actions in the future, liberating craftsmen, farmers, and even slaves...... Although this possibility is relatively small, it has to arouse the vigilance of all nobles and nobles.

But in any case, the identity of the Marquis of Qinghe cannot be easily offended, and the people who offend him basically end miserably, and even the three clans of Zhao Gao, who are the royal family, were abolished as royals and degraded to slaves and sent to Shu.

Although this punishment could not satisfy Chen Xu, in fact, this was already the heaviest punishment for the Great Qin Imperial Family, and the previous Great Qin Imperial Family who was killed was Chang'an Jun Chengcheng.

Cheng Chan was killed because he really rebelled against Qin and surrendered to Zhao, so he was killed in the end, and Zhao Gao was actually far from the point of treason......

When the carriage entered the city, Chen Xu sat in the rickety carriage, looking at the noisy scene of people on the street and the occasional bus speeding by on the street, but he was thinking about the court discussion repeatedly.

"Master Hou, just now the post guard sent a letter!" As soon as Chen Xu returned to the Qinghe Marquis Mansion, the steward came in with a bamboo tube covered with a mud seal to report.

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

"The post man said it was sent from Surabaya County!"

"Alright, there you go!" Chen Xu sat down on a chair in the study, waited for the steward to leave, and then broke the sealing mud before opening the bamboo tube and pouring out a few sheets 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 at all.

The letter from Surabaya County must be Jiangbei Pavilion, and it should be the news of Liu Bang.

Liu Bang, who was originally destined to become Daqin's nemesis, but what would happen when he met him?

If it was really him, how should he deal with it, would he be punished by God for killing such a person who should have become the emperor and forged the backbone of the Han family?

Chen Xu's fingers trembled slightly, and he opened a few sheets of hemp pulp paper, and what came into his eyes was the neat handwriting written by Jiangbei Pavilion himself.

"Jiang's Beiting worships the Qinghe Hou, Beiting to Pei County has been performing his duties for more than a month, keeping in mind the entrustment of the Hou Ye, so he secretly sent someone to inquire about Liu Ji's whereabouts, and really found this person in Surabaya Township, as the Hou Ye said, it is no different, Liu Ji, Chinese New Year's Eve when there are eight, Zhou Yu Wang was born in the winter of 59 years, born in Feng County, his parents are there, four brothers, he studied under Ma Wei in Feng County when he was a child, and studied in Ma Gong Academy, and there is a friend named Lu Huang who was born in the same year, slightly older, does not like to work and is not informal......"

"Liu Ji is ambitious, when he was young, he once traveled to Daliang to surrender to Lingjun, and after no result, he surrendered to Lingjun's guest Zhang Ermen as a guest, Wei Guo was destroyed, Zhang Er was wanted, and the guests were scattered, Liu Ji returned to his ancestral land Pei County, married his wife Lu Pheasant, father-in-law Lu Wen, Shanxian people's family, because of a grudge with people in his hometown and lived in Pei County, and Qianpei County ordered Xu Jing to be a friend, so Liu Ji returned to his hometown after Xu Jing was quite loved, and was placed by the county order as the pavilion chief of Surabaya Township, Liu Ji drank and gambled on weekdays, and was familiar with many officials such as Cao Shenxiao and many other officials in Pei County......

Jiang Beiting didn't dare to be careless about the things arranged by Chen Xu, so he made a lot of effort, secretly inspected Yue Yu, and inquired about Liu Bang's life experience in almost every detail, and wrote six pages of hemp pulp paper.

And these contents are similar to the vague historical records that Chen Xu understands, and even his wife's name is exactly the same as that of Lu Pheasant, and he is really the pavilion chief of Surabaya Township, who doesn't like to work but drinks and gambles all day long, and has a good relationship with the county officials of Pei County, and Cao Shen Xiao He is also a non-existent existence.

In other words, after crossing over, he did not change the existence of any historical figures.

"In order to better control Liu Ji, Beiting promoted him to prison Peng, and secretly arranged for the servants to monitor at all times, and he will not be allowed to get out of the monitoring, about Liu Ji's affairs, he will also write to the Hou Ye in the future, if the Hou Ye has other instructions, he can also arrange a letter to inform him, and Beiting will properly deal with it......"

After reading the last page, Chen Xu put down the letter and sat silently in the study for a long time, then took out a pen and paper and wrote a reply, saying that the letter had been received, expressing his gratitude to Jiangbei Pavilion, and telling him to properly settle Liu Bang, and after he arranged it, he would personally go to Pei County for a trip to Yunyun.

After the letter is written, it is sealed with a bamboo tube, marked with sealing mud and stamped with its own seal, and after it is taken to the kitchen to be dried, it is arranged for someone to send it to the post house so that the servants who pass the letter can send it to Pei County and hand it over to Jiangbei Pavilion.

Since Liu Bang and the description in history are undoubted, then Xiang Yu and Xiang Liang will inevitably appear, and it is estimated that he will receive a letter from Jiang Heng, the Shou of Huiji County, soon.

A day passed in a flash, and it was time for Shen in a blink of an eye.

A school bus from a women's college came and stopped at the gate of the Qinghe Hou Mansion, the doorman steward and a few maids hurriedly greeted it, the car door opened, Yu Ji and Xing'er, two little girls with small schoolbags on their backs, couldn't wait to jump down from the carriage, and were instantly surrounded by several maids.

Shui got out of the car softly, thanked the steward and the groom on the bus, and several little girls poked out of the window and waved outside the car, and at the teacher's goodbye shouts, the school bus departed with a bang, and soon disappeared into the street.

"Squeak~" The door of the study was pushed open, and the water that had changed into the home skirt after washing 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 candlestick on the desk.

"The lady is back!" Chen Xu came back from his contemplation, reached out and took Shui's gentle hand and sat it on his lap.

"What is the husband thinking?" Shui asked softly.

"I received a letter from Jiangbei Pavilion today, and I really found Liu Bang in Napei County, and I didn't know how to deal with him after thinking about it for a long time!" Chen Xu's face was quite melancholy, and he handed the letter on the desk to Shui and said softly.

"Don't worry, husband, you are now the Marquis of Qinghe, and Your Majesty has made the Marquis of Jingyang, these two marquis have never existed since ancient times, it can be seen that Your Majesty attaches great importance to your husband, then Liu Bang is just a commoner, it is easy for your husband to deal with him, there is no need to be so entangled......"

As Shui spoke softly, he began to look through the letters by candlelight, and his face was a little solemn after reading them.
