Coming out of Wang Xuan's house, Li Shimin not only asked Wang Xuan to cook for him, but also had an extra piece of salt making method that he had torn off his robe and dictated by Wang Xuan by his own hand.

On the way back, Li Shimin kept it in his arms and didn't let anyone touch it.

It's no wonder that Li Shimin is so careful, but this method of making salt is too important.

You must know that in ancient times, table salt has always been an equivalent exchange with gold, especially pure sea salt, which is a truly precious thing.

Now with this method of making salt, the rock salt with poison found in the Tang Dynasty before can be made into pure fine salt, with these salts, whether it is eaten by the people or the army marching and fighting in the future, there will be no worries about salt.

Therefore, it is not surprising that Li Shimin, who knows the effect of this salt-making method on the entire Tang Dynasty, is so nervous.

It's just that compared to Li Shimin's nervousness and excitement, Li Xin, who is returning to the princess's mansion at this moment, is a different scene.

As a princess who has been widowed for many years, Li Xin's life is not as good as in the eyes of others.

Although she doesn't have to worry about food and clothing, she wants to have an identity, and with her father and brother winning the world, she herself has become a princess, but in the end she is still a woman, she also wants to be cared for by men, and she also wants to be pampered.

But for so many years, because of her identity and being a widow, the children of the family looked down on her, and those ministers or the sons of ministers also resisted her, so she did not remarry for many years.

In fact, many times, she thinks that she should find someone to marry, but she has never met her.

So this time, when she heard that someone had bought her husband's house and would make mosquito coils that were only available in the palace, she had the urge to go and see it, and that's what happened today.

It's just that when she thinks about all this now, she feels that it is so unreal and incredible, and even secretly scolds herself in her heart for being shameless, and she will be tempted by a man so many years younger than herself.

But what she didn't know was that it was Wang Xuan's concept that was incompatible with this era that deeply moved her, which made her fall into Wang Xuan's love network so quickly.

After separating from Li Shimin, Li Xin was still thinking about the man who made her curious and in love.

And this is a woman, she can fall madly in love with a man after a heartbeat, but men, such as Wang Xuan, he is more in love with Li Xin's beauty and greedy Li Xin's body, if you want to talk about love, there may be a little bit, but it must not be completely in love with Li Xin, this is the difference between men and women.

On the other side, after Li Shimin sent Li Xin back to the princess's mansion, he hurried back to the East Palace.

Back in the East Palace, Li Shimin quickly ran back to the eldest grandson Wuji's bedroom, and before the eldest grandson Wujian asked Li Shimin what he was doing when he left the palace today, Li Shimin directly picked up the eldest grandson Wujian and happily turned in circles.

"Guanyin, do you know? I'm so happy today, I'll tell you, here's the thing............" After the excitement, Li Shimin hugged the eldest grandson Wujian and let her sit on his lap, and talked to the eldest grandson Wujian about all the things today.

In Li Shimin's narration, the eldest grandson Wujian was also told by Li Shimin, covered his mouth in surprise and looked at Li Shimin with an incredible face, and it took a long time to react and ask Li Shimin, "Second brother, what you said is true, there is really a plow in this world that can plow the land without oxen, and there is grain with a yield of up to ten stones per mu."

"These are still unknown, but one thing is definitely true, that is, this method of making salt, after all, I saw the fine salt made by Wang Xuan in Wang Xuan's house, Guanyin, do you know that looking at the delicate and white salt, do you know what I thought? I thought that from now on, Datang will no longer be short of salt, which means that from now on, under the governance of Li Shimin, Datang will not have the pain of soldiers unable to fight and farmers unable to farm due to the shortage of salt," Li Shimin said to the eldest grandson Wujian with an excited face.

"Second brother, if it is really as you said, it is really the blessing of my Li family and the blessing of the Tang Dynasty! If what you said before is also true, then it is really as Wang Xuan said, we don't have to be constrained by that family anymore" After listening to Li Shimin's words, the eldest grandson Wujian also said to Li Shimin with an excited face.

"Yes, you don't have to be constrained by the family anymore, Guanyin you know! The Zheng family, together with the other six, told me that if they want them to support me to ascend the throne and stabilize the economy of the Tang Dynasty, they must make her Zheng Guanyin the queen, or choose a daughter from the seven of them as the queen, don't you say they are too deceitful? Li Shimin said to the eldest grandson Wujian with some anger.

Hearing this, the eldest grandson Wujian was also angry, she never thought that the people of this family would be so shameless.

But she also felt deeply helpless, these five surnames and seven families have not controlled the wealth of the world for a day or two, when her father-in-law crusaded against Wang Shichong of Luoyang, didn't he compromise with several of the seven families to raise enough military supplies, thus laying the foundation for the Li family to dominate the world.

Even behind this Xuanwumen change, there is the shadow of the family.

"Second brother, this matter must not be agreed, they are pouring dirty water on you second brother, just ask the king of the world who comes to the younger brother and sister-in-law, everything who does such a thing will inevitably have no good results, and his family does this, but also wants to tarnish the virtue of the second brother" The eldest grandson Wujian said to Li Shimin with a worried face.

"How can I not know about this matter, otherwise how could I personally kill them, is it true that I, Li Shimin, don't even have the strength to accommodate a group of teenage children, this is just trying to cut off their thoughts" Li Shimin said to the eldest grandson Wujian lonely, his eyes were full of sadness.

Even Li Shimin, in order to deal with the family and want to add some time for himself, has already prepared to include his younger brother's wife in the harem, in exchange for several years.

He understands in his heart that the current Datang can't afford to experience a blow, otherwise with the heavy troops he is now holding, it is not impossible to destroy the five surnames and seven families, after all, military power is the fundamental truth He understands, but he really did it, not to mention that this hard-won peace and unification will be in vain, or even a bad one, the entire Central Plains will be invaded by the alien races around the Tang Dynasty, and then he Li Shimin will really become a sinner through the ages, and this is the capital that the family relies on, don't think it's impossible, think about the powerful Sui at that time, Isn't it just that the family is behind the scenes?

The family has calculated this point correctly, and has always believed that he Li Shimin does not dare to do it, which is why he is so unscrupulous.

But for Li Shimin, he is also confident that as long as he is given a few years, not to mention completely eliminating the family, he can definitely do it by forming a balance.

And the family also needs time at this time, and it takes several years to support one person to fight with Li Shimin, but before the fight, they must let Li Shimin make a big mistake, and this brother and sister-in-law are the way to do a good job.
