After Tang Xun asked the guards to report, he waited for the prince to summon him, and soon after, the white tiger came out, and he said to Tang Xun: "Lord Tang, is your matter urgent?" If not, I suggest you come back in a few days. The prince has been so tired all these years, I hope he can take a good exam and rest for a few days.

The prince came to Yangzhou this time, and he will stay until autumn, you have time to report to the prince, and I will report to the prince about what you have been here, and I will inform you in advance when the prince summons you. ”

Tang Xun's matter is to report on the development of Yangzhou shipyard, as well as the ironclad ship and steam engine, and he is not too anxious. He knew that Li You had just conquered the Japanese slave country, and he should rest for a while.

When he heard Baihu say this, he hurriedly said: "Oh, I don't know if that's the case, it's okay, I'm not in a hurry, then let the prince have a good rest." ”

As Li You's personal entourage, Baihu had never made his own decisions before, and if he dissuaded anyone who asked to see Li You, he would ask Li You's opinion in advance and act according to Li You's instructions.

Today is Li You's first day in Yangzhou, and he is a little tired from the long-term turbulence on the sea, so he rarely didn't get up for morning exercise this morning. The white tiger understood Li You's hard work, and for the first time did something to dissuade the visitor.

In the past, when someone asked to see him, and it was inconvenient for Li You, the white tiger would ask the visitors to wait, and would not let them come back, and then go to report to Li You.

Li You has always been extremely strict with the people around him, and he does not allow them to assert themselves. The eunuchs' dictatorship was caused by using them as the emperor's close attendants to obstruct the emperor's audio-visual.

At nine o'clock in the morning, Li You got up, and the white tiger said: "Lord Wang, the little one is arrogant, please punish the Lord Wang." Then, he asked Tang Xun to see him and reported to Li You how he persuaded Tang Xun.

Li You was slightly unhappy in his heart, but he knew that the white tiger was kind, so he didn't blame him, but just said, "Don't take it as an example." You sent someone to inform Tang Xun and come to see me in three days. ”

Seeing that the prince said that he would only meet Tang Xun three days later, Baihu knew that he had received his love, and said happily: "Yes, Lord Wang, the little one will go and inform Lord Tang." ”

Li You got up, Gao Zhiming had been waiting for a long time, and hurriedly brought breakfast for him. Li You had just eaten a few bites, and Pei Dilan came over, and he said, "Lao Li, Jinling is a good place, let's go out for a walk in the afternoon." ”

Li You played happily for a few days, and there was no interest, so he sent someone to Tang Xun to ask for relevant materials first, so that Tang Xun would not come to the Governor's Mansion to report, and go directly to Yangzhou Shipyard tomorrow to meet.

On the morning of this day, Li You and others came to Yangzhou Shipyard, and saw a large number of factories from a distance, stretching for miles and on a huge scale.

Tang Xun and others greeted Li You and others at the door of the shipyard, accompanied them to visit the factory, watched the test of the steam engine, and then came to the dock dock on the Yangtze River.

The Yangzhou shipyard has a total of 18 docks, which can start construction of 18 warships at the same time, including 5 large warships. Everyone saw that many warships and transports were being built in the dock, and one of them was particularly eye-catching.

This battleship is the ironclad ship designed by Li You himself, this battleship is 126 meters long, 46 meters wide in the middle, with a displacement of 7,430 tons and a capacity of 2,320 people, which is definitely the world's largest ship in this era.

The shape of the battleship was basically similar to that of the first class sail battleship, with 13 masts, but the different bows were sharpened, and the bow and sides were covered with a layer of iron sheets, which increased the impact capacity and the strength of the ship's side, as well as fire resistance.

A large amount of iron sheets were also used in the interior, wrapped in thick wood, and 32 watertight compartments were built, which greatly improved the survivability of the hull.

The height of the deck was lowered, there were no weapons such as clapping poles, stone throwers, and bed crossbows, and rows of square holes were left in the middle of the three decks, and a wooden door was covered outside.

The ship's power system, in addition to the sails on it, also leaves room for a steam engine, which is actually a sailboat. The ship's main power was still provided by sails, with a steam engine as an auxiliary power system.

Although the power of the steam engine is insufficient, it can show its great effect when there is no wind or the wind is too small.

For the Tang Dynasty's strong shipbuilding capacity, Pei Dilan was envious, although the Great Food Empire conquered some coastal countries and had a certain shipbuilding capacity, but compared with the Tang Dynasty, there was a big gap, and the strength of the navy was not the same.

Pei Dilan pointed to the square hole in the deck and asked, "Lao Li, what are those windows for?" ”

Li You smiled: "I'll talk about this after a while, it's not that I'm playing tricks, but that you don't understand it now." ”

This is really not Li You's trickery, those square holes are the firing ports of the artillery, Pei Dilan doesn't know what gunpowder is, and he doesn't understand the artillery.

The construction of this ironclad ship not only relies on the shipyard itself, but also concentrates skilled craftsmen from all walks of life in Datang, which is a concentrated embodiment of Datang's science and technology, and through the construction of this warship, the scientific and technological level of the Tang Dynasty has been greatly improved.

This battleship also represents the highest level of technology in this era, and it is absolutely invincible.

Li You is looking forward to the completion of this giant ship and taking it to travel the world.

The days that followed were uneventful, and Li You spent most of his time in the shipyard, guiding the craftsmen in solving technical problems.

Chang'an City, East Palace.

According to Li You's suggestion, Li Chengqian did a pioneering feat that had never been done in history, he did not move into the palace, but still let Li Shimin and his concubines live, and even the era name still continued the era name of Zhenguan, which won Li Chengqian the reputation of filial piety and played a great role in stabilizing the actual change of dynasty.

The eldest grandson Wuji is the left servant, is the first civilian official, in the domestic peace environment, the actual status is higher than the military generals, is the actual head of the hundred officials, of course, is complacent, as the hero of the new emperor, after Li Chengqian ascended the throne, he first considered to stabilize Li Chengqian's position, after he carefully analyzed, he felt that there are still a lot of hidden dangers.

After Zhang Xuansu ascended the throne of Li Chengqian, the tide rose, not only crowned the Taishi, but also became a scholar, and the eldest grandson Wuji, Wei Zheng, and Hou Junji were called the four prime ministers.

On this day, the eldest grandson Wuji came to the East Palace and said to Zhang Xuansu; "Master Zhang, I don't know why, I'm always a little unsure in my heart."
