Li Shimin said very respectfully:

"What my father said is very true, but Datang can't wait for the canal to be repaired. What's more, there is no way to renovate the canal with peace of mind without beating people who need to be beaten first. The former Sui built a canal of 4,000 miles, which consumed huge manpower and material resources. Erchen thought that only when there were business opportunities could there be coins, and it would make sense to repair the river. ”

At this time, Liu Mu said a rather rebellious sentence in his mouth.

Liu Mu said: "Emperor Yang of Sui, the sin is in the present generation, and the merit is in the future. ”

"This sentence ...... enough to put you in jail." Li Shimin looked at Liu Mu coldly.

Li Yuan smiled: "It's been twelve years." ”

"Father!" Hearing Li Yuan's tone, Li Shimin hurriedly turned around and listened to the training.

Li Yuan didn't speak, just waved his hand lightly, and after everyone retreated farther, Li Yuan said: "If our family is defeated, it will be a chaotic minister and thief, or Wang Shichong's fate." Since you have won, it is better to be generous, Mu is good, the sin is in the present generation, and the merit is in the future. ”

"Father is wise." Liu Mu hurriedly came to say.

Li Yuan also smiled coldly: "It's not that I, an old man, am wise, but you really got to the point this time." If you say that there is something good about the former Sui and something bad. This can be discussed, this canal repair is indeed a good thing, and I Datang also need to repair the canal. ”

Li Shimin added on the side: "Father, this machine made of wood is not only for ships, it is to pull each carriage that can hold 600 stones, a total of forty or fifty. At a speed of one hundred and sixty miles per hour, the dragon car galloped in the south and north of the Tang Dynasty. ”

"Why didn't you see this dragon car?" Li Yuanxin said that being able to run on land has more advantages than running in the canal.

Li Shimin didn't speak, and motioned for Liu Mu to explain.

"Father, there are several reasons right now. The first is that the machine is not powerful enough, at least five times larger, to make a train. Another reason is that trains need special roads, which require huge manpower and material resources. One of the most important reasons is that Datang's steel is not enough, not even a fraction of it. ”

Li Yuan nodded: "Think long-term." ”

"What my father said is that this is a long-term plan, and there is only this one ship at the moment, and it will really make this ship work, how can it be that it will not be meaningful until half a year later, when there are more than ten ships."

Li Yuan stroked his beard and squinted at the dock.

Li Shimin stood next to him and did the same thing.

The father and son were thinking about the same thing, that is, whether the ship should be seen by the hundred officials.

At this time, Liu Mu said: "Second brother, why do you have to give ten or eight officials." ”

Li Shimin glanced at the craftsmen standing on the periphery waiting for inquiry, and then waved his hand to signal Li Dejian to step forward.

Li Dejian came to Li Shimin and stood aside after giving a salute.

"Your father fought abroad and made great contributions to the Tang Dynasty. The tiger father has no dogs, although you have no ability to lead the army, this matter is done well, and I am very happy. According to the rites, when your father's pharmacist is rewarded by the Ministry of Rites, you will also be rewarded as the eldest son. You have merit, but when your father triumphs, he will be rewarded and I will protect your title above the county. ”

"Thank you, saint." Li Dejian immediately gave a salute.

Li Shimin said: "From now on, you will lead the Ministry of Labor to serve as a supervisor. I ask you if this ship can be fully equipped on the fifteenth day of the first lunar month. ”

"Yes, it can be done in three days, but the paint is inconvenient, and it is winter at the moment, so it is not suitable for painting."

"That's good, on the afternoon of the fifteenth day of the first lunar month, the boat will be tested on the wider river of Weishui. At that time, the Ministry of Rites will give you two actual eight-rank officials, six nine-grade officials, and twelve nine-rank loose officials. Go back and prepare the list, and prepare new clothes for those who have done merit, and then receive the reward and be sealed. I will also write a letter in my own hand, telling your father about your merits. ”

"Thank you, sage, the minister retires." Li Dejian bowed heavily, then stepped back, and then left with the craftsmen.

After Li Dejian and the craftsmen left the dock for about a few hundred steps, they talked about the reward, and the craftsmen shouted in ecstasy.

Li Shimin also smiled when he saw this.

Liu Mu stepped forward: "Second brother, a general from the sixth rank will be a prisoner, isn't it too stingy." ”

Li Shimin asked with a smile: "What do you want, Sipin Guan?" ”

"Not really, it's just that Li Dejian hasn't answered for three years, it's very hard, and he was originally eating at home and waiting for death, and he can also get benefits with Pharmacist Li's military exploits, at least at the level of a flying cavalry captain."

Li Shimin shook his head slightly: "Not only that, when the Western Expedition returns from victory, he must be the captain of Zhaowu." There were several benefits to it, which he had earned on his own, and this was only the beginning. Before the train runs, there will be at least three more seals, so five seals in the next three years, you don't understand. ”

"Okay!" Liu Mu also heard that he really didn't understand the skill of this reward.

Li Shimin didn't say anything about it again.

Li Shimin said to Liu Mu: "Tomorrow, I will write an article on your sin in the present and your merit in the future." If you don't have that confidence, you can find someone to catch the knife. After it is written, it will be sent to the palace, and it will be printed tonight, and the front page of the Chang'an newspaper tomorrow. ”

"Yes!"

Liu Mu originally thought that he would not return to Chang'an in Jingyang tonight, but because he said a few more words, he would need to rush back to Chang'an.

Li Shimin was also ready to go back, but the eldest grandson Wujian didn't plan to leave.

"Erlang, there's also a small steam engine here, much smaller than the one on the ship. The craftsmen will hurry up and adjust it, and it is estimated that it will be able to use it in the evening. I want to see it for myself. ”

The eldest grandson, Wuji, gave Li Shimin a reason.

Li Shimin asked again: "Is it a boat?" ”

"No, it's for the yarn mill. A steam engine was built in the house next to the mill, and then connected to the house by a transmission rod, and many belts were hung from the mill. ”

Li Shimin probably understood.

Originally, the yarn machine was made to rotate by water or animal power, and this steam engine can carry the huge paddle wheel, and it must also be able to drive the yarn machine.

"Guanyin, you should take a good look at this, if it is really useful. If you want to come to Datang, you need to build more steam engines, which can be used in weaving mills and mills. ”

"What Jiro said is that I heard that this steam engine has countless uses. Huayuan Coal Mine is in use, and it is thousands of times faster than the previous speed of relying on people to carry coal. ”

Li Shimin hesitated for a while, if it weren't for the fact that he needed to consider the impact of the steam engine on the Tang Dynasty, then he would have stayed to watch the steam engine drive the spinning machine.

The things on Jingyang did not deliberately hide from anyone.

When Liu Mu had not returned to Chang'an, there were already rumors in Chang'an that there were boats without sails and oars in Jingyang, but they ran faster than the horses.

Pulling grain weighing 10,000 stones, it can still swim upstream, and the speed is faster than that of a horse-drawn cart, etc.
