Yang Jie felt that he needed Xu Guang's support to promote a new knowledge system in this Jinshi class. With Xu Guangqi's support, he could compile textbooks. Mathematics, agriculture, and even physics, and astronomy were available, and the three major classes could be opened as soon as possible. Therefore, it is very important to obtain Xu Guangqi's support. Otherwise, relying on Yang Jie to go to Baidu teaching materials one by one, Yang Jie would explode.

"I still heard that Master Xu had planted sweet potatoes himself?" Yang Jing remembered that in the court, an official had heard from Xu Guangqi grow sweet potatoes himself. Planting sweet potatoes was a powerful tool to defend against natural disasters in the late Ming Dynasty.

In the late Ming Dynasty, the so-called heaven and region were intertwined, and there was nothing wrong with it. Sweet potatoes, like gold fingers, had already existed. When Yang Jingwei Baidu Xu Guangqi, he also discovered that this sweet potato had been vigorously promoted, but I don’t know why it did not achieve much practical results.

When heaven and the region were intertwined, the light of heaven once shone on the land of the Ming Dynasty, but people abandoned him and ran to hell themselves.

Whenever he thought of this, Yang Jing felt a pity and felt uncomfortable. Now that he was traveling over and became Emperor Chongzhen, then this sweet potato would not have to open the golden fingers of his own. As for the matter, he would also promote it with all his strength, so that the light of heaven would be closer to the Ming Dynasty.

"Your Majesty, I have indeed planted it." Xu Guangqi was asked by the emperor, and his many years of ambitions were realized by this young emperor.

"Then tell me how Master Xu was growing this sweet potato. I heard that the sweet potato has extremely high yields, very low yields to the ground, and also drought-resistant. I think that in the Ming Dynasty, there are natural disasters and droughts, and I need these drought-resistant crops that are high-yield!"

"Your Majesty, this thing is indeed there. I have planted it many years ago. This thing has no high requirements for the land. It can be planted in ridges, hillsides, and barren lands. The yield is indeed extremely high and it is relatively drought-resistant. It is a magic weapon to fight against natural disasters and droughts. It can only be planted in the south. I try my best to cultivate new varieties suitable for the northern climate... I ask Your Majesty to promote it in the world and prevent the people of the world from persecution of disasters and famines..."

Xu Guangqi can be said that he spent a lot of effort on this sweet potato. When he first entered China, he could only plant it in the south and was not very suitable for the cold and arid climate in the north. Xu Guangqi selected seeds and optimized the variety so that sweet potatoes could be planted in a drought and cold north. He wanted to use this kind of relief to alleviate disasters in the north. It can be said that he was worried about the country and the people.

Just imagine, a Jinshi did not pursue fame and fortune in the officialdom, but calmed down and focused on growing sweet potatoes for the sake of the country and the nation, and improved the varieties of sweet potatoes. This kind of sentiment and spirit is really admirable.

"Master Xu is loyal and patriotic, which really makes me admire him." Yang Jingwei didn't know what to use to praise Xu Guangqi. He wanted to save the Ming Dynasty and needed many like-minded people to help him. Xu Guangqi was obviously a trustworthy "comrade". Since he was his own person, he would not say much nonsense and would not look at the advertisements and see the efficacy.

"I also know that this sweet potato is the only magic weapon to fight against natural disasters, but there is no effective promotion method. I think those landlords will not change to plant sweet potatoes because of the high yield of sweet potatoes. The grain is much better than planting sweet potatoes. Even if it is a drought, some harvest will be lost. However, ordinary people still have to pay enough land rent and taxes first. Therefore, drought has little impact on landlords. Their enthusiasm for growing sweet potatoes may not be too high. Ordinary people will also have to plant food because of the high price of food. Otherwise, growing sweet potatoes will not even pay the land rent and taxes. In this way, how can sweet potatoes be promoted? Master Xu has a way?"

Yang Jing did not think about using sweet potatoes to fight drought, and he had thought about it for 80 times. However, there was no specific good way. Yang Jing considered that in the late Ming Dynasty, land annexation was quite serious. The landlords would not grow sweet potatoes because of the high yield of sweet potatoes. For them, no matter how dry or famined they were, they would only harvest a little bit of food and would never be hungry. The price of grain is rising step by step, and growing grain is far better than growing sweet potatoes. Growing sweet potatoes may only be the common people who use the fields to grow some, so the scale is absolutely impossible, but it will only be small. Therefore, relying on sweet potatoes to fight natural disasters is good, but they cannot calculate the economic calculations, but it is not very feasible. Yang Jing was very worried about this matter and has never had any good solutions.

After hearing what Emperor Chongzhen said, Xu Guangqi sat there and pondered for a long time before saying, "Your Majesty, it seems that I am thinking too simply. I thought that with this magic weapon to fight drought, more people will definitely be able to fill their stomachs, but I didn't expect that it would be difficult to promote this!"

Xu Guangqi sighed a long sigh, his expression became much weaker. It seemed that the difficulty in promoting the issue that Chongzhen mentioned was indeed a problem. Xu Guangqi himself was also a ruling class and a landlord. Of course, he knew the price of this grain. In the north, the price of grain was that sesame seeds bloomed, rising and rising year by year. In the past, it was only one tael of silver and one stone. Now, it gradually increased to more than one tael, two taels, good rice, or even more than two taels to buy. Therefore, if you ask others to give up planting traditional grains with high value and plant sweet potatoes, unless the per mu output value of sweet potatoes is higher than that of traditional grains, even if the sweet potatoes are said to be in the sky, it is impossible to plant them on a large scale. It is just a very nice empty saying.

An Guoli's ambition to be liberated to childbirth. The long-distance fatigue made the elderly Xu Guangqi even more tired, and he was almost sleepy. After seeing this, Yang Jie felt very heavy and felt uncomfortable.

This old man was worried about himself, for the country, and for the Ming Dynasty that was about to slide into the abyss, and tried his best to do anything, but he still couldn't help the people as he imagined. I guess he must have suffered extremely painfully and had a great blow.

Yang Jie thought about it and asked the respectable old man to have a good rest. He just came to the capital and had not had time to rest, but he was called into the palace to discuss matters. He was too unkind. He called in a low voice: "Big companion, please help Master Xu to rest in the warm room." He was afraid that he would wake up Xu Guangqi.

When Xu Guangqi heard the emperor's words, he was shocked and seemed to wake up from his deep sleep. He knelt down and said anxiously, "Your Majesty forgive me for your crime. I am guilty of being guilty. I deserve to die." Xu Guangqi was so tired. He had just arrived in Beijing and had not had time to rest. He was summoned to the palace by the emperor and discussed things. It was originally a happy thing. He won the emperor's trust and value to realize his ambitions. However, his ambitions seemed simple, but it was indeed unlikely to be realized. This blow to Xu Guangqi was so great that he was tired and depressed, and he actually fell asleep. It was really disrespectful to lose his manners in front of the emperor.

"It doesn't matter. Master Xu is tired from a long journey. It's my fault. He shouldn't be so busy with Master Xu. He should have settled down first and have a good rest. In this way, a great companion will help Master Xu to the warmhouse for a while. I won't talk about state affairs today. In addition, Master Xu goes to Beijing thousands of miles away despite his old age and weakness. His loyalty and patriotism are commendable. He will reward him with a thousand taels of silver and ten pieces of brocade..."

Yang Jingwei was in a heavy mood.
