The most elite troops of the Datang Shence Guard and the border army are pure firearms troops.

Inferior elite units use pure steel heavy armor units.

At present, only in the Datang Ordnance Division to solve the problem of gunpowder waterproofing in rainy and snowy weather, then Datang will give up the heavy armor troops and turn all into firearms troops.

Li Shimin can calculate the lethality of the firearms unit without actual combat, and 5,000 people will not be killed or wounded more than 1,000 if they kill 100,000 enemies.

After more than a thousand years, the development process of this firearm will definitely be even more terrifying.

Therefore, Li Shimin is concerned about the people's livelihood, the people's livelihood represents the national strength, and it is the national strength that fights the war.

When he heard that the Indochina Peninsula alone exported 100 million stone of rice every year in later generations, Li Shimin smiled.

Food is people's livelihood, and people's livelihood is national strength.

At night, Dugu Lanruo sat on the edge of the bed and asked Liu Mu, "Why didn't you tell me before?" ”

"What do you want me to say, say that I borrowed something to return my soul." Yanagi is reluctant to admit the word resurrection of the corpse.

If Dugu Lan didn't speak after listening, what Liu Mu said couldn't be said to be unreasonable, this kind of strange and chaotic thing is really not easy to say, at least it will make people think that he is crazy, and at worst he may lose his life.

Liu Mu sat next to Dugu Lanruo: "Actually, I wanted to talk about it before, but I didn't know how to speak at that time, and slowly I couldn't find a chance to speak." It's actually nothing, and no one will believe it when it is really said, but I plan not to say it for the rest of my life. ”

Dugu Lanruo glanced at Liu Mu and asked, "I am in the history books, how do I write it?" ”

This question, Liu Mu's whole person who asked was cold.

"How?" Dugu Lanruo felt very strange after seeing Liu Mu's reaction.

Liu Mu said: "No, there is no record at all, according to common sense, at least a few words will be mentioned in the biography of Princess Pingyang." And in the real history, Xie Yingdeng retired to the mountains and forests after the Tang Dynasty. And then there's ......"

Liu Mu didn't say any more, but he figured it out in his heart.

"This is the theory of the space-time axis that I first talked about, which is not the same Datang as the space-time I am in, it can only be said to be similar, but not exactly the same, that's all."

Liu Mu figured it out, if there was no Dugu Lanruo, there would be no opportunity for him to participate in the Xuanwumen incident.

Dugu Lan couldn't understand what the space-time axis was, and asked, "So the eldest brother-in-law's side?" ”

"He, he has a special biography, and the history records it is very clear."

"Really!" Dugu Lanruo stretched out her hand and twisted it fiercely on Liu Mu's waist when she spoke, and said while twisting: "Then you tell you, have you ever thought about finding a chance to marry a real princess, or a gate valve family......

This topic is a proposition.

It's not something that can be solved at the level of intelligence.

Li Shimin, Liu Mu and the other four stayed in Sanyuan Xiaozhuang for a few days, but they talked a lot.

A few days later, on the day the four of them returned to Chang'an City, the Tang Emperor Li Shimin handed a bill to Shangshu Province, asking for the matter to be discussed in the autumn cabinet.

On duty in Shangshu Province is Du Ruhui, Yao Silian, one of the five elders of the Ministry of Industry and the cabinet.

The two were shocked when they saw Li Shimin's proposal.

"This ......"

Yao Silian was shocked and brought Li Shimin's proposal to Du Ruhui.

Du Ruhui was also taken aback when he saw it: "If there are minors in the family, the tax on 15 acres of land is exempted, and the two daughters are one ding." For every additional ding in the family, ten acres will be exempted from land tax, and 100 acres will be the upper limit. Craftsmen are calculated according to the monthly income, and each mu is converted into seventy-five Wen, and Jingzhao and the provincial capitals and counties increase or decrease according to the local income. ”

After Du Ruhui finished reading, he looked at Yao Silian.

Yao Silian said: "Although you and I are not working in the household department, this account can also be calculated. According to this calculation, based on the average of three dings per household, the annual treasury revenue on the per capita tax will be reduced by tens of millions of yuan. ”

Du Ruhui nodded, this number is quite amazing.

"Someone." Du Ruhui gave an order, and immediately two scribes stepped forward.

Du Ruhui sealed the bill and handed it over: "Send it to the household department, let the two servants of the household department read it, don't spread it, and I will discuss it with Yao Gong and them in a few days." ”

"Yes!"

The scribe retreated, and Du Ruhui said to Yao Silian: "The household department will definitely be able to calculate how much less tax will be paid every year." However, if the treasury income of tens of millions of yuan can be supported by Datang, think about it, if it is an average of three dings per household, then the population of Datang will increase by thirty and a half percent every ten years, and the population of Datang will increase by as much as seventy percent every twenty years. ”

Yao Silian nodded: "This is the fifth time since the founding of the Tang Dynasty that a national policy has been set to increase the population. ”

"The first four times combined are not as good as this one."

Du Ruhui wrote another document, the content of which was to ask the Ministry of Household to carefully calculate, if the tax exemption for population increase becomes incremental, then what kind of incremental method is more appropriate and reasonable.

It was also sealed, and someone was sent to send it again.

This proposal of the Tang Emperor Li Shimin has not been circulated, but has only been circulated on a small scale within the high-level of Shangshu Province, the Six Ministries, and the cabinet.

This is already the scope of a major national policy, and the important ministers have been discussing the feasibility, reliability, national benefit, and people's benefit of this national policy in private for several days.

Li Shimin was also in the palace discussing this topic with Liu Mu.

"Second brother, I have made this matter very clear, when the commercial tax is very perfect, and when the state-owned key workshops are operating well, the grain tax is really exempted. It even gives money to many growers, as well as workshops that the state needs. At the moment, I don't know if it's good or bad to be exempt from food tax. ”

Liu Mu's words are the truth, the times are different, and the grain tax does not dare to be exempted.

Li Shimin was full of confidence: "This matter is also a proposal, and the cabinet must have been discussing it in private." Whether it is feasible, whether it is against or in favor of it, requires a detailed analysis and plan. Not to mention that one ding is exempt from ten acres, even if one mu is exempted, it is also a merit and a popular heart. ”

"That's right!" Liu Mu very much agreed with Li Shimin's words.

At this time, someone came in to report.

"Report, the Ministry of Rites sent people to come, and the Goguryeo envoy Yuan Pure Land went to Laizhou by sea, and went to Chang'an by land through Qizhou, and he had arrived in Huazhou at this time. Wenyue Pavilion also sent someone to report, and Wenyue Pavilion sent a copy of the Yuan Pure Land file to the Goguryeo branch. ”

Li Shimin motioned to leave the file, and then waved his hand to retreat.

Li Shimin didn't look at the file, and pushed it in front of Liu Mu.

Liu Mu opened the file and looked through it and said: "Second brother, Wenyue Pavilion has begun to have some doubts about the analysis of the Yuan clan, this Yuan Pure Land is estimated to have come to test something, Wenyue Pavilion is over there to analyze, one is Baekje, the second is Maoshan, and the third is Liaocheng." ”

"Liaocheng?" Li Shimin was a little surprised.
