In addition to the fine steel sword, there is also the famous Tang Dao among the remaining weapons. This Tang Dao is a general term for Tang Dynasty knives, which include four categories: Yi Dao, Heng Dao, Mo Dao, and Barrier Dao. Among them, Yi Dao is The ceremonial saber, and the remaining three are munitions, all of which are equipped with the army.

Li Yin asked the craftsmen to forge the horizontal knife and the barrier knife. These two kinds of knives are long and short, and are used to equip infantry. The Mo knife has a short handle and a long blade, which is more than twice as long as the horizontal knife. For cavalry, the land of Shu is surrounded by mountains, and the barbarians in the south basically have no cavalry, so Li Yin only allowed a small amount of Modao to be produced for the time being.

In addition to the knives, Ouyang Wang asked the craftsman to bring two more pieces of armor. These two armors were made according to the drawings given by Li Yin. They used European-style full-body armor. The full-body helmets of the period have high protection ability, but this kind of armor is very heavy, so Li Min decided to use aluminum alloy to make the full-body armor. The reserves of aluminum are higher than iron. There are several aluminum mines in Yizhou, although pure aluminum has low hardness. , but the hardness of the Lu alloy mixed with other metal elements is not low, and it does not even belong to fine steel.

The two armors that Ouyang Wang brought were made of steel, and the other was made of pure aluminum. Li Yin took the armor made of steel and tried it, but it was really too heavy. There is no need to fight, and the lightness of this pure aluminum is very light, but the fine steel sword will be broken with a horizontal cut.

Li Yin asked Ouyang Wang to build these two pieces of armor only to let him be familiar with the production of full-body armor. The production of aluminum alloy also requires various rare metals. Li Yin is going to buy a batch of these metals and put them in Taoyuan for the production of aluminum alloy armor. It is obviously not realistic to look for mineral deposits, and not many rare metals are used in aluminum alloys.

   Satisfied with the work efficiency of the blacksmiths, Li Yin decided to go back and purchase the pulleys, bow strings and rare metals he needs now.

Leaving the blacksmith shop, Li Yin went to the village again. At this time, Du Pingzhi was experimenting with the imitated steam engine, Tong Yu was experimenting with artillery, and Guo Xianyuan was studying a few firearms that Li Yin brought. Everything was going on. In the middle, Li Yin was relieved.

  In the evening, Li Yin went back to the modern villa to order the materials he needed, and also bought a batch of small carts and manpower tricycles. What the Tang Dynasty lacked was manpower, and these things could save a lot of manpower.

   At the same time, Li Shimin's southern tour team returned to Chang'an, and the conversation between Li Shimin and Li Yin in Yizhou also spread among officials in Chang'an City through the mouths of interested people, and the government and the public criticized it for a while.

After resting for a few days, Li Shimin came to court on this day. When he walked into the Taiji Hall, he felt the solemnity in the court hall that was different from the past. As soon as he sat down, Wei Zheng came out and asked, "Your Majesty, I heard the words Your Majesty wants to confer the title of His Royal Highness King of Shu as the governor of Yizhou, in charge of the military and administration of the ten prefectures of Shu, just like a vassal king, I don’t know if this will happen.”

  Li Shimin also planned to discuss this matter this morning, so he said: "Yes, this is exactly what I mean. I am going to discuss this matter with all my loves this morning."

   "I didn't expect this to happen!"

   "The governor has always been a remote leader."

   "Is this the prince?"

   "..."

   Li Shimin personally admitted this matter, and the ministers immediately whispered to each other. Li Shimin had already prepared for the reaction of the ministers, and he had made up his mind. Whether they agreed or disagreed, Li Yin was sealed.

  Wei Zheng continued: "Did Your Majesty forget the Rebellion of the Seven Kings in the Western Han Dynasty and the Rebellion of the Eight Kings in the Western Jin Dynasty?"

"Of course I haven't forgotten, but I am not Emperor Jing of the Han Dynasty, and the Tang Dynasty is not the stupid Western Jin Dynasty. Moreover, I appointed the sixth prince as the governor of Yizhou for the prosperity of the Tang Dynasty. Yizhou is a narrow place. Except for Yizhou, The other prefectures combined are not as good as Yizhou, so there is nothing to worry about, and it is a great achievement for Li Yin to volunteer his skills, and he deserves it!" Li Shimin said frankly.

As soon as Li Shimin's words fell, another minister came out, but it was Lu Jin. He said: "The meritorious ministers of the sixth prince are very admired, and it is not a bad idea to entrust him with the land of ten states, but the emperor should let the sixth prince get it later. All the skills are reported to the court and shared with the people, and there are many skilled craftsmen in Chang'an, who will surely carry forward these skills."

   "Words of integrity!"

   "It is the skills that should be handed over."

   "..."

After Lu Jin finished speaking, there was a voice of agreement. These are officials from prominent families. They don't worry about whether Li Yin is the king of Shu and how many states and counties he controls. To them, Shu is just a chicken rib. What he cared about was what was in Li Yin's hands.

Li Shimin glanced at the echoing courtier and said: "Then I would like to ask, what if the sixth prince is not willing to give these skills? After all, Luo Anguo has only done business with the sixth prince so far. How many skills he has mastered are only him. I know that maybe what is recorded here is just a drop in the bucket, that's why I handed over all ten states to him, and Min'er will definitely do his best for his fief and will not hide his personal interests." Li Shimin took out the gift that Li Min had donated The booklet was shaking in his hand, immediately attracting many greedy eyes.

"This..." Zhang Liang glanced at Li Tai, Li Tai nodded to him, Zhang Liang said: "Your Majesty can send imperial envoys to Yizhou, and let Princess Shu return to Chang'an as a hostage, as long as Yizhou has new skills Let the king of Shu hand it over when he appears, and he dare not refuse at that time."

   "Bastard!" Li Ke was furious when he heard the words: "Zhang Liang, what is your intention? Taking the princess of Shu as a hostage? I am Li Yin's brother, why don't you take me as a hostage?"

Then Li Yin came out and looked down on the officials and said: "Father, the world is the Li family. In the early years, Father abolished the enfeoffment system and did not divide the princes. It was originally for the stability of the world and to avoid chaos among the princes. There is nothing wrong with it. Now it is for the prosperity of the country. The strong people enfeoffed the land of Shu to Li Min, not for private purposes, but for the sake of the public, and there is nothing wrong with it, and my ministers agree with my father's decision!"

What Zhang Liang said just now, not only Li Ke was sullen, but Cui Shao was also very angry. He came out and said: "Your Majesty, the sixth prince suffered unfair injustice and was relegated to Yizhou, not to mention, this has just happened in Yizhou. As a result, there are some people with ulterior motives who can't see the merits of the sixth prince, and want to win the skills in the hands of the sixth prince, but for their own selfishness, just as the third prince said, your majesty is for the public, but some people are for selfishness , Your Majesty, please enlighten me!"

Li Shimin nodded appreciatively. He didn't tell the truth to all the ministers just now. Firstly, he came to make Shu land rich under Li Yin's governance. Secondly, he left a bloodline in Yizhou to guard against these powerful families. If one day they have different intentions that are not good for the Li royal family, they should also consider Li Yin who is in Yizhou.

   "Cui Shizhong's words are wrong. Doctor Zhang's strategy is a bit inappropriate, but Li Yin's skills are not as good as everyone knows. This is beneficial to the Tang Dynasty, isn't it?" Fang Xuanling said slowly.

"Mr. Fang Ge still doesn't understand what His Majesty means. This skill is in the hands of the Sixth Prince. How much to hand over is up to the Sixth Prince. Could it be possible to send an imperial envoy to get the Sixth Prince to hand it over? Besides, let Princess Shu go to Chang'an as a hostage. For the sixth prince, it is a shame and a great humiliation, not only will he not give up his skills, but he will also hate the court, so it is difficult to say what will happen." Cen Wenwen spoke.

"I also think that Dr. Zhang's words are inappropriate. To intimidate the Sixth Prince for some tricks, wouldn't this chill the Sixth Prince's heart and make the world ridicule, but I still don't agree with His Majesty's breaking the enfeoffment system." Wei Zheng listened a few times Fang debated, refuted Zhang Liang's words and poured cold water on Li Shimin.

Li Shimin has been observing the expressions of the ministers. After Zhang Liang's words, many officials from the aristocratic clans showed their praises. There were chills, if they could treat Li Yin like this today, they might be able to treat other princes like this in another day, and even treat him like this, which made him more determined.

  Everyone insisted on their own opinions and couldn't agree with each other. At this time, Changsun Wuji came out and said: "Your Majesty, I have a way to get the best of both worlds."

   "Let's listen to it!" Li Shimin was overjoyed, thinking that Changsun Wuji was the one who won his favor the most.

Changsun Wuji pondered for a while and said: "All the ministers are worried about is that the sixth prince will become a vassal king, but you must not forget that in the Western Han Dynasty, the fiefs of the princes and kings could be hereditary, and they could mint money privately in the fiefs. Taxes are collected without being managed by the court, and it is like a country."

After a pause, he continued: "As for the ten prefectures of Shu, I think that one of them cannot be hereditary, and that Li Min will return to the imperial court after his death. The third is not to mint money privately, and the fourth is to let Li Min assume the responsibility of guarding the border. As long as these four points are achieved, I believe that the ministers will not have any objections." Changsun Wuji knew that Li Shimin had made up his mind, It's useless to persuade others. After all, Li Shimin is the emperor, he can listen to what the courtiers say, and the reason why he said this is after careful consideration. Prohibiting money casting and taxation is to control Li Min's money, while guarding the border is to control Li Min's money. Min's army was controlled in the land of Shu. Once Li Yin died in battle, the land of Shu would return to the court.

As soon as Changsun Wuji's words were spoken, there was a burst of discussion among the ministers. Many people secretly thought that Changsun Wuji was still old-fashioned, and that Shu was adjacent to Tubo in the west. This is a superpower that coexisted with the Tang Dynasty. Throwing this burden on Li Yin, the Guanlong Group will have one less trouble, and will not need their own children to go to the battlefield to fight hard.

   "This..." Li Shimin hesitated, "I can agree to the first three things, but it would be too embarrassing for Li Yin to assume the responsibility of guarding the border."

  Changsun Wuji said: "Not doing this is not enough to convince all the ministers, please think twice, Your Majesty."

   "Your Majesty, please think twice, otherwise I would rather die than obey!" Lu Jin took the lead and knelt down, and soon Li Chengqian, Li Tai and the others all knelt down, only Li Ke and Cui Shao's people were still standing.

  Cheng Yaojin, Lu Shang, and Xiao Yu were in a dilemma, neither of them wanted to offend, and finally said: "The minister waits for a second opinion!"

Li Shimin looked at the minister kneeling on the ground, smiled angrily, and said: "Okay, I promise you these four conditions, but guarding the border is the responsibility of the vassal king, so from today on, the land of Shu will be renamed Chengdu Mansion, and the title of Li Shimin will be changed." The king of Chengdu, enfeoffed the ten prefectures of Yi, Mian, Mao, Jia, Song, Ya, Sui, Zi, Qiong, and Yu."
