Yang Gai felt that he needed Xu Guang's support to promote the new knowledge system in this Jinshi class, and with Xu Guangqi's support, he could compile textbooks, such as mathematics, agriculture, and even physics and astronomy, 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 Reform to go to Baidu teaching materials one by one, Yang Reform will explode his brain.

"I also heard that Master Xu personally planted sweet potatoes?" Yang Gengai remembered that in the court before, he heard an official talk about Xu Guangqi's own sweet potato planting. Planting sweet potatoes, which in the late Ming Dynasty, was a great weapon to defend against natural disasters.

At the end of the Ming Dynasty, the so-called heaven and region were intertwined, and it was not wrong to say that sweet potatoes were against natural disasters, similar to goldfingers, and there were already things, when Yang reformed Baidu Xu Guangqi, he also found that this sweet potato had been vigorously promoted, but I don't know how it didn't achieve much practical results.

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

Every time I think of this, Yang Reform feels a pity, and it is not a taste in my heart, now that I have crossed over to be Emperor Chongzhen, then, this sweet potato, I don't need to open my own golden finger, no matter what, I must also make every effort to promote it, so that the light of heaven is closer to Daming.

"Your Majesty, the minister has indeed planted." Xu Guangqi was asked by the emperor, and it was even more whimsical, and his ambitions for many years were about to be realized in this young emperor.

"Then tell me quickly, how Master Xu is planting this sweet potato, I heard that this sweet potato, the yield is extremely high, the land has to go very low, and it is also drought tolerant, I think I am in the Ming Dynasty, now it is a natural disaster, drought continues, and this drought-tolerant, high-yield crop is needed!"

"Your Majesty, there is indeed this thing, the minister planted it many years ago, this thing, the requirements for the land are indeed not high, ridges, hillsides, gravel and barren land, can be planted, the yield is indeed extremely high, and it is relatively drought tolerant, it is really a magic weapon to fight against natural disasters and drought, it can only be planted in the south, the minister tries his best to cultivate a new variety suitable for the northern climate...... please Your Majesty, be sure to implement it in the world, so that the people of the world will be free from the persecut......ion of the famine."

Xu Guangqi can say that for this sweet potato, it took a lot of effort, sweet potato, when it first entered China, it could only be planted in the south, not very suitable for the cold and arid climate of the north, Xu Guangqi selected seeds, optimized the variety, so that the sweet potato can be planted in the arid and cold north, and wanted to alleviate the disaster in the north in this way, it can be said that it was heartbroken for the country and the people.

Just imagine, a jinshi, not to chase fame and fortune in the officialdom, but to calm down, for the country, for the nation, concentrate on planting sweet potatoes, improve the varieties of sweet potatoes, this kind of feelings and spirit, is really admirable.

"Master Xu is loyal and patriotic, which really makes me feel admired." Yang Reform didn't know what words to use to praise Xu Guangqi. If he wants to save the Ming Dynasty, he needs a lot of like-minded people to help him, and this Xu Guangqi is obviously a trustworthy "comrade". Since it's my own person, I won't talk much nonsense, and I don't look at the advertisement to see the curative effect.

"I also know that this sweet potato is the only magic weapon to fight against natural disasters, but there is no effective way to promote, I think those landlords will not change to sweet potatoes because of the high yield of sweet potatoes, growing food is far better than planting sweet potatoes, even if it is a drought, lose some harvest, but the common people still have to pay full rent and taxes first, so, drought, for the landlords, has little impact, their positive surname for planting sweet potatoes may not be too high, and the common people will also grow food because of high food prices, even if it is a natural disaster, they have to grow food, Otherwise, planting sweet potatoes can't even pay land rent and taxes, so how can sweet potatoes be promoted? Does Master Xu have a way? ”

Using sweet potatoes to fight drought, Yang Reform didn't think about it a hundred times, but also thought about it eighty times. But there's no concrete way to do it. Yang reform considered, in the last years of the Ming Dynasty, the land annexation was quite serious, the landlord class, will not because of the high yield of sweet potatoes, can fight the drought will plant sweet potatoes, for them, no matter how drought, no more famine, they just harvest a little less grain, it is impossible to go hungry, and the price of this grain is high, growing grain, far more than planting sweet potatoes. Planting sweet potatoes can only be common people using the fields to plant some, so the scale can never be large-scale, it will only be small-scale, so it is good to rely on sweet potatoes to fight natural disasters, but it is not economically calculated, but it is not very feasible. Yang Gai was so troubled by this matter that there was no good way to do it.

Xu Guangqi heard Emperor Chongzhen say this, sat there and pondered, and after a long time, he said: "Your Majesty, it seems that the minister is thinking too simply, thinking that with this magic weapon to fight drought, more people will definitely be able to eat their stomachs, but I didn't expect that it will be difficult to promote this!" ”

Xu Guangqi let out a long sigh, his expression was depressed a lot, it seems that Chongzhen said that the problem of difficult promotion is indeed a problem, Xu Guangqi himself is also the ruling class, but also a landlord, of course he knows the price of this grain, this north, the price of grain is sesame blossoming, higher and higher, higher and higher year by year, it used to be only one or two silver and one stone, and now, it has gradually risen to one or two more, two taels, good rice, and even more than two taels can be bought. Therefore, you want others to give up planting traditional grains with high value and plant sweet potatoes instead, unless the yield per mu of sweet potatoes is higher than that of traditional grains, otherwise, even if this sweet potato is said to be in the sky, it is impossible to plant it on a large scale to fight against natural disasters, which is just a very nice empty word.

……

An Guo Limin's ambition suffered from dystocia, and the long-distance fatigue made the elderly Xu Guangqi even more tired, and the whole person was almost sleepy.

This old man, for himself, for the country, and for the Ming Dynasty, which was about to slide into the abyss, broke his heart and tried his best, but he still couldn't help the people as he imagined.

Yang Gai thought about it, or let this respectable old man have a good rest, just came to the capital, and before he had time to rest, he was called into the palace to discuss things, he was too unkind. He whispered: "Big mate, Master Fuxu should take a rest in the warm pavilion." "I'm afraid of waking Xu Guangqi.

Hearing the emperor speak, Xu Guangqi seemed to wake up from his slumber, and hurriedly knelt down, uneasy, and said: "Your Majesty forgives the sin, the minister has no form, and the crime deserves death." "Xu Guangqi is too tired, a long-distance trip, just entered Beijing, before he had time to rest, he was summoned into the palace by a holy decree of the emperor to discuss things, it was a happy thing, to get the emperor's trust and reuse, to realize the ambition in his heart, but the ambition in his heart, but it seems simple, but in fact it is impossible to achieve, this blow to Xu Guangqi is too big, so that fatigue hits the body, the spirit is sluggish, actually sleepy, in front of the king, it is really disrespectful.

"It doesn't matter, Master Xu's long-distance fatigue is all my fault, I shouldn't be so anxious to bother Master Xu, I should let Master Xu settle down first and take a good rest, in this way, my companion, help Master Xu to the warm pavilion to rest for a while, and I won't talk about state affairs today." In addition, despite his old age and infirmity, Master Xu went to Beijing thousands of miles away, and his loyalty and patriotism were commendable, and he was rewarded with a thousand taels of silver and ten horses of brocade......"

Yang reform's mood was heavy.

Xu Guangqi seemed to have run out of energy, and he didn't have any extra energy to do anything else, and after thanking him, he was helped by Wang Chengen and walked out with a little staggering steps.
