On the vast sea, the tall warships of the Tang Army sailed on the sea.

Hou Junji led the Tang army fleet from Chengshan (now Rongcheng, Shandong), crossed the Yellow Sea, and went straight to Nanpu City at the mouth of the Datong River.

Hou Junji was on a sea boat for the first time, and it was a little fresh at first.

The shipbuilding industry of the Tang Dynasty was the most developed in the world at that time.

The main types of ships commonly used in the Tang Dynasty sailors were building ships, ships, and buckets

Ships, boats, yachts, and sea boats, etc.

Hou Junji is on a falcon ship, is a kind of large warship, "although the wind and waves are angry, and there is no roll", it is this type of ship will not sink even in the strong wind and waves, obviously because it has quite good seakeeping and stability, it will be called an all-weather warship, with a total length of 22 zhang, and can carry 700 people.

The warship is very large, and it is stable, and the wind and waves at sea are not big, but Hou Junji, the duck, still suffers. After 5 days of vomiting, he finally started to get used to it.

Li Zhi, the king of Jin, has a cowardly personality and is not a managerial talent. But he's smart and a good material for learning. Since entering the technical school, Li Zhi has made rapid progress.

Li found that Li Zhi was very obsessed with scientific research. Li Zhi often went to the research institute. He quickly grasped the novelty of the scientific and technological products in the research institute.

Not only that, he often came to the East Palace to ask Li Su for advice.

Li Su is well aware of the importance of navigation to the future development of Datang. He had always wanted to find a figure to work on navigation and shipbuilding.

This character must have a scientific and technological mind, as well as an identity status, and Li Zhi is a very suitable candidate.

On this day, Li Zhi came to the East Palace and saw a beautiful model of a sea falcon warship on Li Su's table, which aroused his interest.

The two brothers started from warships, talked about the shipbuilding industry, talked about the interesting stories of navigation, the importance of navigation to the future development of Datang, and so on. Li Zhi showed great interest.

When Li Su saw that there was a door, he asked the craftsmen to make a batch of models of sea ships, tempting Li Zhi from time to time. Li Su talked about his desire to develop the Tang Navy, and Li Zhi volunteered to serve as the director of the Naval Research Institute.

On this day, Li Zhi asked to see Empress Changsun.

Li Zhi said: "The queen mother, the son wants to be the director of the Naval Research Institute. ”

Empress Eldest Sun smiled: "Okay, Zhi'er is out, and the queen mother has no opinion." ”

Li Zhi said: "As the director of the research institute, I will leave Chang'an and go to the southern coastal areas. ”

Empress Changsun was reluctant to let him go, but Empress Changsun was a smart person, she knew that Li Su would become the emperor sooner or later, and Li Zhi could wait for his reuse, and the future would be guaranteed.

Besides, Li Zhi is a prince, he is 16 years old this year, and when he is 18 years old, he will also leave Chang'an. Instead of this, it is better to let Li Yu arrange it for him, so that he can maintain his brotherhood, which is a good choice for Li Zhi.

Empress Changsun knew that Li Su was not a narrow-minded person, and he could tolerate Li Chengqian, Li Ke, Li Tai, and Li You. Li Zhi and Li Su have always had a good relationship, and Li Su will not deliberately target Li Zhi.

She thought for a while and said, "Okay, Zhi'er, the eldest husband has ambitions in all directions, so you can go." ”

Li Su's deputy to Li Zhi, one is Huang Qi. Huang Qi is shrewd and capable, and can handle all kinds of affairs for Li Zhi, ensuring that Li Zhi can focus on scientific research.

The other deputy is Tang Xun, who is currently the ambassador of Yangzhou Dao Shipbuilding. Tang Xun was a top master of shipbuilding during the Zhenguan period of the Tang Dynasty, able to make his own shipbuilding drawings, and had experience in organizing and managing the shipbuilding industry.

In particular, the fact that the self-made shipbuilding drawings are remarkable. It was not until a thousand years later, in 1633, that anyone in Europe was able to make their own shipbuilding drawings.

The Datang Naval Research Institute was established, with Li Zhi as the director and Huang Qi as the deputy director. Li Zhi selected a large number of students and craftsmen from the Ministry of Industry and the Industrial School, and left Chang'an for Yangzhou.

Yangzhou is bordered by the river and the sea, and has developed water transportation, and has been an important hub for north-south transportation since ancient times. Since Emperor Yang of the Sui Dynasty opened the Grand Canal, Yangzhou has become the center of the country's water transportation and salt transportation in the Sui and Tang dynasties, and it is also an international port open to the outside world on the Maritime Silk Road. (Yangzhou here does not refer to the current Yangzhou City, but a large area including Yangzhou City.) )

The most critical thing is. Yangzhou was one of the largest shipbuilding bases in the Tang Dynasty.

After Li Su's proposal, the fief of Li Zhi, the king of Jin, was changed from Hedong Province to Yangzhou.

Empress Changsun was very grateful to Li Su - Yangzhou is one of the richest regions in the country.

At present, Datang does not have a unified navy, and the navy is under the jurisdiction of each province. Li Su wanted to integrate the navy and unify it into the Northern Fleet and the Southern Fleet.

The candidate for the commander of the Navy, he decided to use Cheng Chumo. Cheng Chumo is 28 years old this year, a first-class earl of the Tang Dynasty, from the third rank general, there is no problem with identity and loyalty. Just give him a deputy.

Li Su searched on Baidu and found a well-known naval admiral talent.

On this day, Liu Renliang, the county leader of Liyang (now Lintongbei, Shaanxi), was chatting with the county magistrate. Not long ago, the imperial court made personnel adjustments. Liu Renliang, who was originally very popular, was not promoted.

The county order thinks that Liu Renliang is a talent and is unhappy for Liu Renliang. Liu Renliang said: "Lord County Order, you are only 30 years old this year, and you are already a county order, I am already a year of not being confused this year, and this is the case in my career, I should retire the year after tomorrow, and I have no ideas." ”

At this moment, a servant came in to report that someone was coming from the East Palace, and the county magistrate and Liu Renliang hurriedly went out to greet him.

The person who came was a personal entourage of the prince of the East Palace, and he said, "Which one is Lord Liu Renliang Liu?" ”

Li Shimin received the prince's report, he had no opinion on the establishment of the Naval Research Institute and the integration of the Tang Dynasty's navy, and he was still familiar with Liu Renliang. Liu Renliang served as the county governor (now Lintong North, Shaanxi), and he was personally promoted.

Liu Renliang was originally the county lieutenant (director of the public security bureau), and Cao Luning, Chen Canghu, was proud of his high rank, arrogant and rude, and no one could stop it. Liu Renliang persuaded him with kind words and ordered him not to commit it again. But Lu Ning not only did not relent, but intensified, and Liu Renliang threw him into prison.

Lu Ning did not repent in prison and abused Liu Renliang. In a fit of rage, Liu Renliang beat Lu Ning to death with a cane. Seeing this, officials in Qizhou (Zhiyong County, now Fengxiang, Shaanxi) hurriedly reported to the imperial court.

When Li Shimin heard about this, he was furious, and he was a little curious about Liu Renliang's audacity, so he sent someone to escort Liu Renliang to Chang'an and question him face to face.

In the face of Li Shimin, Liu Renliang was fearless, and said calmly: "Lu Ning humiliated the minister in every way, and the minister really couldn't help but kill him." ”

At that time, Wei Zheng was beside Tang Taizong, and when he saw that Liu Renliang was upright, he said to Tang Taizong: "Your Majesty knows why Sui perished? In the last years of the Sui Dynasty, Diao Min was arrogant and bullied officials, which was like Lu Ning. ”

After Li Shimin listened to Wei Zheng's words, he turned his anger into joy, so he promoted Liu Renliang to Liyang (now Lintongbei, Shaanxi) County.

On this day, a very special guest came to Chang'an City.
