Looking at Zhang Gao's anxious appearance, Li Chengqian knew that something important must have happened, otherwise Zhang Gao would not have such an expression.

"Say it! Is something going on?" When Li Chengqian came to the study with Zhang Gao, he looked at Zhang Gao and asked.

"Your Highness, the specific situation, the old slaves are all summarized here, please take a look" said Zhang Gao cautiously took out a booklet from his arms and handed it to Li Chengqian.

Li Chengqian took the booklet handed by Zhang Gao and quickly flipped through it, but Li Chengqian was angry the more he flipped through it, and finally slapped the table with his hand angrily.

"This family, they are really looking for death, they are so disregarding the life and death of the people, and want to shake my Li family's country, do they think that my Li family can't afford to hold a knife, but you think that's it, Zhang Gao passed on the king's order, let the farms around the country take out the grain in stock, lower the price of grain for the king, and let the Ming Wei out to the king, but anyone who incited the people will be brought back for strict interrogation, and the investigation of those who raise the price of grain will be increased, but anyone who evades taxes and evades taxes, and colludes with officials and businessmen will be arrested. And let those workshops under the eldest princess go all out to squeeze the share of the family's various industries, go" After speaking, Li Chengqian asked Zhang Gao to go down and do things.

After Zhang Gao left, Li Chengqian sat on the desk, sorted out what he had just said, and then took the materials he had written and rushed to the direction of the Taiji Palace.

When Li Chengqian rushed to the Taiji Palace, his father and his various ministers were there, but they were all sad, and there were still a few broken teacups on the ground of the Taiji Palace.

"Father, aren't you just some clowns jumping off the beam? Why be so angry with them" After Li Chengqian entered, he said to Li Shimin on the dragon chair!

"Stinky boy, what do you know, this time, if you don't handle it well, then Datang will smoke again, but if you come here at this time, is there anything you can do about it" Li Shimin sat on the dragon chair, looked at his eldest son and asked suspiciously, after all, he knew that his eldest son, if he had nothing to do, he would not come over easily.

And the eldest grandson Wuji, Du Ruhui and they all looked at their father and son blankly when they heard the conversation between Li Shimin and their father and son, and even Li Shimin's final question also made them puzzled for a while, if they hadn't followed Li Shimin for a long time and knew his character, they might have jumped out to refute it a long time ago, after all, they all thought that there was no way for the talented advisers, what could a young man who was not as good as the crown do.

"Father, I have the way, but you have to promise that after I say it, you can't beat me, and you can't let my mother beat me, if you agree, then I'll tell you" Li Chengqian looked confident, and said to his father, who was now sitting on the dragon chair, frowning.

"Stinky boy, you really have a way, as long as you have a way, then not only will I not blame you, but as long as the method is feasible and can solve this crisis, then you can do whatever you want, except that, you know" Hearing that his eldest son really has a way, Li Shimin looked at Li Chengqian excitedly and said, as for the last words, Li Shimin did not say it clearly, after all, the prince of a country, thinking about not being the prince all day long, even in front of his closest minister, he couldn't say no, so he could only fight with Li Chengqian.

And the eldest grandson Wuji and Du Ruhui on the side, when they heard that the crown prince Li Chengqian really had a way, they all stared at Li Chengqian.

"His Royal Highness the Prince, you really have a way, then come quickly, the ministers are in a hurry now" Although Du Ruhui didn't know what Li Chengqian's method was, but now that they really can't think of a way, it's good to listen to it, maybe Li Chengqian's ideas will give them something to mention, with such an idea, Du Ruhui said to Li Chengqian anxiously.

"Du Xiang, don't be impatient, wait for my father to read it, it's not too late for you to watch it, father, we have said it" Li Chengqian first said to Du Ruhui, who was in a hurry, and then handed the materials he had written before to his father while talking.

Li Shimin, who took the materials, couldn't wait to look at it, and Li Shimin felt good about the methods of attacking the family in the materials, and even the analysis of the family was in place.

"Gao Ming, your materials are good, but there is one point, what kind of corn, potatoes, and sweet potatoes, they can really support it, your plan, you must know that once these grains cannot let the people of Datang settle down, the final result will be that we want to compromise with the family, and may even cause turmoil in Datang" After Li Shimin finished reading it, he handed the materials to the eldest grandson Wuji and them, and then said to Li Chengqian.

"Father, I know what you said, but I am very confident in potatoes, sweet potatoes, corn, after all, these crops are very high-yielding, almost all of them are crops with a yield of more than 7 stones per mu, and the yield per mu of potatoes is as high as 20 stones, this is only in the mountains and other barren places, if it is in the fertile land, the yield per mu is higher, so father, you don't have to worry about the food will not be enough, let's put it this way, the grain stored in our farms around the country, not to mention more, just let the people eat enough, That's two years and I can't finish eating" Li Chengqian said to himself, and when he finished speaking, he found that his father and eldest grandson Wuji were all looking at him one by one.

"Gao Ming, what you just said, but it's true, and what's going on with those farms" Li Shimin looked at Li Chengqian with wide eyes at the moment and asked.

"Of course it's true, I can't lie to you, as for the farm, that father and emperor, you have to remember, two years ago I asked you for a place to secretly train recruits in various places! After all, there was no war at that time, so I asked people to plant potatoes, sweet potatoes and corn in large quantities," Li Chengqian said to his father with some embarrassment.

"It turns out that you and I asked for this at that time, but I really want to know, since you know these crops, the yield per mu is so high, and you got it a few years ago, why don't you take it out, but hide it like this, and tell me why" After listening to Li Chengqian's words, Li Shimin stared at Li Chengqian with a gloomy expression and asked.

"That, this, I ......" Li Chengqian was asked like this, and he didn't know what to say.

"Keming, auxiliary machine, you take this material, according to the above plan, deploy manpower, cooperate with the implementation of this plan, if there are any shortcomings, you discuss it first, you go and get busy first!" Looking at his eldest son's hesitant and looking left and right, Li Shimin had already guessed the reason, but in front of the eldest grandson Wuji, he couldn't say anything, so he had to let them leave first.
