The harmfulness of the Liukou is naturally undoubted, so whether it is for the stability of the Ming Dynasty or the continuation of Chinese civilization, Yang Feng cannot allow the tragedy of history to repeat itself.

However, Yang Feng suddenly remembered another question, and he looked at Cao Huachun.

"Gonggong Cao, Benhou remembers that the imperial court has vigorously promoted drought-tolerant, high-yield crops such as potatoes, corn, and sweet potatoes in Shanxi, Shaanxi and other places over the years.

Cao Huachun was stunned for a moment, and then smiled bitterly: "Master Hou, you can knock our family down." Our family is just a slave serving Your Majesty, this kind of national affairs should be known by a vulgar person like our family, and it is not too late for you to ask Your Majesty after you return to Beijing. ”

"Vulgar?" Yang Feng laughed, looked at Cao Huachun carefully for a long time, and saw that he was a little chilly, and then smiled: "If even Grandpa Cao is a vulgar person, I am afraid that so many talented people in the Ming Dynasty will have to commit suicide in shame." ”

Yang Feng's words are not exaggerated, according to historical records, Cao Huachun's family was humble when he was young, and he entered the palace at the age of twelve or thirteen under the influence of the atmosphere of "close to the monarch and raising relatives". Because of his talent, diligence and studiousness, he received a good education in the palace, and was proficient in poetry, calligraphy and painting, and was deeply appreciated by the eunuch Wang An, who relied on him as a cronie.

It can be said that with Cao Huachun's cultural level, if he participated in the imperial examination, he would not dare to say that he would be in the first class or the top in high school, but he would not have any problem entering the second class.

was pierced by Yang Feng's words, Cao Huachun smiled a little embarrassedly, "Master Hou is really as wise as a torch, and he can't hide anything from you." In fact, with the vigorous promotion of potatoes, sweet potatoes, corn and other grains in the past two years, the grain of the imperial court has indeed increased a great income, but most of these grains have been hoarded by the gentry.

Jiangnan and other places are better, after all, it is a heavy tax area, although the people are not very rich but there is still a stutter, but Shaanxi and other places are different, there has always been barren, most of the fields are in the hands of the gentry, as the climate has become colder and colder in recent years, those gentry have covered the grain more tightly, and easily refused to sell the grain, so it also makes the food more and more scarce.

Our family estimates that it is precisely because of this reason that the bandits in Shaanxi and Shanxi are becoming more and more suppressed. ”

Yang Feng's gaze froze: "Speaking of which, the reason why there are more and more rogues is not a natural disaster, but a man-made disaster?" ”

Cao Huachun said with certainty: "It can't be said that it has nothing to do with the sky, but if there were no rich and unkind gentry behind the scenes, the scourge of the rogue would never have been so big." ”

"Man-made disaster!"

After Yang Feng repeated a few words in his mouth, a faint murderous intent appeared in his eyes.

Nowadays, Yang Feng spends a huge amount of money every year to introduce high-yield seeds from modern society, and in a few years, Yang Feng spent more than one billion yuan on this area alone, and his original purpose was to help Daming through the difficult Xiaoice River period, he never thought that the good seeds were brought back, but on the contrary, it cheapened those landlords and gentry, which Yang Feng did not expect.

"Good...... It's good, it seems that Ben Hou did something bad this time. ”

Yang Feng didn't laugh angrily.

"It seems that next year, Benhou will have to carefully review the whereabouts of those high-yielding seeds."

"Don't ...... Don't ......" Cao Huachun was so frightened that he almost didn't pee out, and his hands were like windmills, "Master Hou, my ancestor, we can't control what you do, but don't tell me that this matter was told to you by our family, and we beg you." ”

Cao Huachun couldn't help but be afraid, as high-yield seeds flowed into Daming one after another, the demand for high-yield seeds in various places also increased geometrically.

The corn, potatoes, sweet potatoes and other grain seeds that Yang Feng brought to the Ming Dynasty are generally divided into two types, one is high-yield seeds, but these seeds will degrade after planting, so new seeds must be purchased every year.

Another type of grain seed does not degrade, but the yield of these seeds is very different from that of high-yielding seeds.

It stands to reason that the gentry and landlords of this era were not fools, and they naturally knew how passive they would be if they were in the hands of others.

But people are like that, once you taste the sweetness, it's hard to go back. For the same acre of land, the yield of different seeds is fifty percent or even one or two times different, and such a disparity in yield is that even fools know what to choose.

The demand for high-yield seeds in the Ming Dynasty is also increasing, which also means that those landlords and gentry are more and more dependent on the Ming royal trading houses, once Yang Feng decides to personally review the whereabouts of high-yield seeds, or redistribute them, I am afraid that the entire Ming Dynasty will be shaken.

That's it, if you let those people know that it is because of him Cao Huachun crooked his mouth in front of Yang Feng, I am afraid that Cao Huachun will become the public enemy of the landlord class in an instant.

Yang Feng was naturally not afraid of holding the lifeblood of those people in his hands, but how could he, Cao Huachun's small arms and legs, be able to block the counterattack of those people.

Looking at Cao Huachun, who was so frightened that his face turned pale, Yang Feng laughed and patted him on the shoulder, "Okay, Lao Cao, don't worry, it's nothing to do with you, just put your heart in your stomach, it won't implicate you." ”

After listening to Yang Feng's comforting words, Cao Huachun smiled reluctantly, "Hou Ye's words are naturally listened to by our family, I just hope that if someone asks for trouble with our family in the future, Hou Ye can help our family, and our family will be grateful." ”

Yang Feng smiled and said to Song Ye who was standing at the door: "Okay, Ben Hou already knows about this, Gonggong Cao will go down to rest first, and it will not be too late for Gonggong to return with the boat after the weather improves in a few days." Song Ye, send the public down to rest, and by the way, give another thank you gift to the father-in-law. ”

Cao Huachun stood up, saluted Yang Feng, and retreated with Song Ye.

After Cao Huachun retreated, Yang Feng thought for a while before sighing lightly, "The mountain rain is coming, and the wind is full of buildings." ”

The next day, the Jiangning army continued to attack the city, and this time Yang Feng replaced the siege troops with the second and fourth battalions.

The second and fourth battalions, which had already been gearing up, had already been holding back after learning that it was their turn to play, and they were already holding back and attacking one by one as if they had been beaten with chicken blood. In particular, Huang Jiye, the commander of the second battalion, even transferred dozens of eight-pounder guns and twelve-pounder guns to shoot at close range.

Seeing that the second battalion actually came up with this method, the fourth battalion naturally did the same, and for a while, the entire San Petro Castle was running loudly, and one building after another was turned into ruins in the smoke of gunpowder.
