Under the Baqiao, Lu Hanyang's boat was blocked, and on the shore, ox carts, carriages, and porters were constantly unloading. Lu Hanyang's spiritual sense shrouded him, and he found that large ships were unloading goods on the dock, all of which were rice.

"This ...... The army has only now begun to deliver grain and grass, and I am afraid that it will be a month before it really sets out. Are you just waiting here? No way! Lu Hanyang took the two little girls ashore, and then headed towards Chang'an City.

"Father (Emperor)." entered Chang'an City, came to the palace, and took Li Lizhi and them to see Li Er. Li Lizhi and Xiao Wu saluted Li Er, and Li Er saluted Lu Hanyang.

"Immortal Chief, what kind of wind is blowing you down the mountain! Xiao Ke is trying to find the immortal chief. Li Er said.

"Is it a matter of mobilizing troops against the northern steppes?" Lu Hanyang asked.

"The immortal chief's eyes are like torches, it is indeed because of this matter. This matter was not so anxious, but now there is an opportunity, if you don't seize it, Xiao Ke is not reconciled. Li Er said.

"What about the prairie? What kind of opportunities? Lu Hanyang asked.

"The Turks wooed the Hui and made Xue Yantuo feel the crisis, and asked my Tang for help, and we sent troops to directly support Xue Yantuo, and wiped out the Turks and the Hui Hui. And subdued Xue Yantuo, so that the northern frontier would have no worries. Li Er said.

"Is this news reliable? Xue Yantuo is not a person to be slaughtered, what if they are unwilling to become bigger? Lu Hanyang asked.

"This is also the reason why Xiao Ke wants to go to the Immortal Chief, Xiao Ke wants to let the Immortal Changsui army go out together, there is no need for the Immortal Chief to charge into battle, only the Immortal Chief needs to deter the three tribes of the grassland in the war. In this way, they will definitely not dare to offend my Datang Tianwei! Li Er said.

"It's a beautiful idea, but what do you use to convince this seat? This seat is not from the Nether Realm to help you Li Tang expand his territory. Lu Hanyang said, how do he want to go, after all, he is used to living a leisurely life, so he doesn't want to run around like this.

"Immortal Chief, this ......" Li Eryu was speechless, he never thought about Lu Hanyang's situation if he didn't help Datang.

"Why, I can't think of a reason to convince this seat?" Lu Hanyang said.

"If the Immortal Chief is willing to help the Tang Dynasty, then the Human Sect will be the State Religion of the Tang Dynasty, and the ten miles around the Jade Mountain will be assigned to the Bajing Palace as private property, and everything will be disposed of by the Immortal Chief!" Li Er said.

Ten miles in a radius, say big is not big, say small is not small. However, it includes the entire Jade Mountain, and there are thousands of acres of fertile land around it. It's not that Li Er is unwilling to give more, but Yushan is only thirty miles away from Chang'an, and Chang'an will be given out if he gives more.

"This seat doesn't want these things from you, and this seat is not the kind of person who needs much glory and wealth, as long as there is food, drink, and a place to live. How about this throne want the emperor to make a promise to you? Lu Hanyang said.

"Immortal Chief, please speak!" Li Er didn't agree directly, after all, he didn't know what conditions the other party would propose.

"This seat wants the emperor, how about you not collect agricultural taxes?" Lu Hanyang asked.

"This ...... How is this possible, and how can this huge empire run without taxes? How can we make the country strong when the treasury is empty? You can't ...... it," Li Er couldn't agree.

"It seems that the emperor still doesn't understand what is the way to strengthen the country!" Lu Hanyang said.

"Immortal Chief, no tax is absolutely impossible, without taxes, how to distribute money to officials, how to help victims in disaster years, how to build water conservancy, how to pay military salaries, all of this is based on taxes." Li Er is like a cat with its tail stepped on.

"Emperor, do you think about how much harvest you can get in a year? How much is the yield of an acre of land in a year, and how much land does a farmer plant? Lu Hanyang asked.

"A farmer, even if it is a family of three and two men, according to the uniform field system, the male Yongye field is 20 acres, the sub-field is 80 acres, and the female is halved. After calculation, a family of three also has 50 acres of Yongye field and 200 acres of sub-farmland. A total of two hundred and fifty acres of land. ”

Li Er said, in this way, one mu of grain is about two to three stones, and according to two stones, a family also has 500 stones of grain. This is a lot, according to the tax method of rent adjustment, a person pays two stones of grain, which is called rent.

Pay two zhang of silk, three taels of cotton, or two zhang and five feet of cloth, and three catties of hemp are called tunes. The standard of using three feet of silk or three feet of cloth and seven inches and five minutes of cloth instead of twenty days of conscription per year is called yong.

Together, these three are rent-yong adjustments, which were the main way to collect taxes in the Tang Dynasty, and these merchants, because of their large mobility, are inconvenient to collect taxes, so they can only pay taxes from the original place of origin, and then the local government gives a tax payment certificate, and then no taxes are collected.

This method is very primitive, compared to these farmers, the tax of the merchants of the Tang Dynasty is the same as that of the farmers, and it is also rent-oriented, but they pay a little commercial tax when they buy things in the place of origin.

"Emperor, taxes are not collected in this way, although I don't understand it, but I know that if a country's commercial tax is not the main source of taxes, then it is definitely not normal." Lu Hanyang said.

"Businessmen, they have no output, and it is true that they should be taxed for profit, but how can commercial taxes become the mainstream tax of the state? This is impossible, my Datang's annual commercial tax is less than half of the agricultural tax, which cannot meet the needs of the state. Li Er said.

"Maybe it's like this now, it's just because of the war, so that the businessmen had no intention of operating before, you look at it, in a few years, Chang'an City will have thousands of dollars in their waists, and rich businessmen with 100,000 yuan in their waists will appear, and even millions of dollars are not necessarily impossible." Lu Hanyang said.

"This ...... However, it is also an indisputable fact that business is now withering. Therefore, Xiao Ke can't promise the immortal chief, and it is indeed difficult to do it without tax! Li Er said.

"Forget it, I don't know the trick of it, but the Emperor of Commercial Tax can let people investigate it carefully, and the taxes collected by merchants are absolutely unreasonable. What is the reason for the tax only when you buy raw materials? Lu Hanyang said.

According to the shallow commercial tax insights of later generations, Lu Hanyang knew that for things like luxury goods, the tax was often more than half of the selling price. For example, for Porsche sports cars, taxes account for more than 80 percent of the selling price.

Such a thing needs to be verified by various practices before it can be settled.

"Immortal Chief, Xiao Ke can promise Immortal Chief, if Immortal Commander goes with the army this time, Xiao Ke can reduce the agricultural tax as much as possible, how much will the commercial tax be increased, and how much will the agricultural tax be reduced?" Li Er said.

"This ......" Lu Hanyang thought about it, the commercial tax is definitely getting higher and higher in a stable environment, and after gaining enough experience in commercial taxation after exploration, Datang's commercial tax will definitely rise rapidly, which means that the agricultural tax will be rapidly reduced.

Even in the end, it is not impossible to achieve such a thing as subsidizing the state for farming, if that is really the case, then the life of the descendants of this Tang Dynasty will be truly rich.
