After reading it here, Li Xiang came to another grain-producing area, where wheat was planted just now, and potatoes were planted here.

In the 21st century, the average potato yield can reach 5,000 catties per mu, and if the management is good, 8,000 to 10,000 catties is also possible, and the seeds exchanged in the system are the best, and it is written that it is also 8,000 to 10,000 catties, and Li Xiang doesn't know how much can be produced here.

This side was dug up in advance, so in addition to their own people, the other people also left, so you don't have to be so careful when you speak, in fact, you don't need to send people to watch at all, after those farmers dig this thing out, they don't think it's food at all, and they also think that His Highness is wasting the land.

The yield per mu is 9,000 catties, which is qualified.

Then Li Xiang went to see the sweet potatoes non-stop, as long as it was exchanged from the system, Li Xiang planted it in the experimental field, and at present, the seeds of the system are no problem, in order to carefully inspect Li Xiang also tasted it, it is indeed possible to cultivate on a large scale.

At present, Li Xiang has purchased nearly 6 million acres of land in the country, and has almost become the largest landlord in the country, of course, these lands are not concentrated in Li Xiang's hands, all of them are exchanged from the system, and after giving them a false identity, they have become small landlords of all sizes, so that they can also get away with the confusion, one is to deceive the five surnames and seven wangs, and the other is to deceive Li Shimin.

If all wheat is planted, according to the yield of 2,000 catties per mu, it should be able to support nearly 30 million people, but now according to what Li Xiang has learned, there are at most 20 million people in the whole country.

After calculating this matter in his heart, Li Xiang breathed a sigh of relief, since he was reborn to the present, what Li Xiang is most afraid of is not the countries around him, but the five surnames and seven hopes.

In the 21st century, Li Xiang knew a fact, the Tang Dynasty was so strong, who was he defeated? After reading the entire history of the Tang Dynasty, Li Xiang knew that the Tang Dynasty was defeated by himself.

The elite Chang'an Forbidden Army is the strongest army in the country, and the Hedong Border Army in the hands of An Lushan is also one of the strongest armies in the Tang Dynasty.

Although there is no army in the hands of the five surnamed Qiwang now, there are a lot of people they have arranged in the court and the army, once they are tough with them, it will not be good for the current Tang Dynasty, and they must slowly cut their flesh, but the conflict over the years is not small, Li Xiang and Li Shimin are worried about the same, that is, food.

If they use this as a weapon, Li Shimin may not be able to recruit them, especially when foreign wars break out, they have to rely on them to send grain, if these people are unwilling, then the military rations may be cut off at any time.

Now Li Xiang can finally breathe a sigh of relief, although he has only mastered a very small part of the country's arable land, but he has been able to feed the people of the country, and after a few months of grain harvest, Li Xiang can establish his own grain sales network in the country, and slowly devour the foundation of the five surnames and seven hopes.

"How's the sale of Shioji?"

Li Xiang suddenly thought of another matter, if he hadn't gone to Tuyuhun to get this agreement, maybe he would also participate in the auction of Yanyin.

"The major families are crazy about buying, the original pattern has been broken, and now the emperor is very satisfied, just waiting for us to put the best salt on the shelves all over the country, and then the major families will not be more expensive than us, they will lose to death."

Qian Ping has been collecting news about this, about the auction of Yanyin, Li Xiang and Li Shimin can be said to have made enough money, when the major families pooled money before, they put a large amount of collateral in Li Xiang's hands, and that time was the first time Li Xiang cut their leeks.

When auctioning the salt lead, they auctioned the salt lead in their hand at a price more than twice the actual price, which was equivalent to being cut by Li Shimin again.

In the process of being leeks twice, the property of their entire family has dropped by at least 20 percent, don't underestimate this 20 percent, for a huge family, even one percent of it is a huge amount of property, just take the matter of selling salt leads, Li Xiang earned nearly 8 million yuan.

Li Shimin's side made a little less money because of the lack of business operations and the lack of a capable person to manipulate him, but he also earned nearly three million yuan, which is already equivalent to a quarter of the annual tax revenue, and also improved the financial embarrassment of the Tang Dynasty in disguise.

"The biggest loss should be the Taiyuan Wang family, right?"

Li Xiang remembered the family that reported to Tuyuhun, who used to be the largest salt merchant.

"Your Highness is wrong, in this auction, the one who lost the most was the Li clan in Longxi."

When he heard this, Li Xiang turned around with some surprise, Li Shimin claimed to be the Li family of Longxi, why didn't he deal with the Taiyuan Wang family, did he actually trap his own family?

"I don't blame anyone for this matter, if you want to blame it, you can only blame the people of the Li family in Longxi for being too greedy, they want to take one-third of the salt merchants in the world by auction, and now it is estimated that they are celebrating, just waiting for our salt to go on the market, then they should cry."

Qian Ping's description is very apt, according to the price at the auction, each catty of salt must be sold for fifty yuan, so that it can be worthy of his auction price, and this is still the lowest salt.

But Li Xiang priced the whitest kind of salt at 500 yuan a catty, and the following is divided into several grades, I am afraid that the salt merchants will not be able to set the lowest grade to 50 yuan, and the price of all grades in the middle will be reduced, according to their pricing strategy, the highest grade should be about five yuan. Li Xiang pulled them down tenfold at once, once the salt of the treasure was put on the market, then they would wait to sell the pants.

"No matter who they are, they are all stumbling blocks on the road to Datang's development, and they can be kicked out at any time."

Whether it is the Taiyuan Wang family or the Longxi Li family, as long as one of them can get out of this shock, it will not be in vain to arrange for such a long time.
