Three Kingdoms: Me! Liu Zheng! Queen Jing of Zhongshan!

"This..." Li Ren's eyes wandered from side to side, looking at the two deans, and he didn't know what to say for a while.

"I think the dean is interested in your ability to do those new things. Zhang Ji added at this time.

Hua Tuo nodded in agreement: "Yes, I just like your ability to study those things."

"Then what should I do?" Li Ren listened to the words of the two deans, and also recalled, and found that it was indeed like this, Li Ren, who had long regarded Liu Zheng as his only belief, knew Liu Zheng's affirmation of his ability, and he specified that he wanted to repay Liu Zheng by exerting his ability in this regard

! "Of course, I have given full play to your specialty! Although I don't know so much, I know that the lord is going to..."Zhang Ji said in a deep voice, and then pointed to it with his index finger, hinting.

"Then we need to be strong and strong, what our medical school can provide is not to let the soldiers have no illness and no

disaster, and the injured can be treated?" "As long as the soldiers under the main account are strong and strong, and there is no disease and no disaster, then it is invincible

and invincible!" "Isn't this the greatest help we can provide?" Zhang

Ji, who is a little more sensitive to politics, analyzed to Li Ren.

"That's right!" Li Ren clapped his hands, immediately realized the point, and thanked Hua Tuo and Zhang Ji: "Thank you two masters for waking me up."

After Li Ren had an epiphany, he immediately threw himself into a series of ideas.

For example, how to quickly heal war injuries such as knife wounds and burns of soldiers, and how to treat them in the simplest way on the battlefield.

There are also solutions or antidotes to some of the major plagues that are most likely to occur in war.

For a time, Li Ren's subordinates opened dozens of laboratory teams.

......

Liu Zheng, who left the medical hall, took Liu Zheng and Xia Houlan to the College of Agriculture.

Although it is said to be an agricultural college, it is actually located in a large field outside the city.

A large area under the corner of the wall near Zhengding City is all allocated to the Agricultural College for research on increasing crops.

The dean of the College of Agriculture is Chen Lao, a local farmer in Zhengzhen County who has been honest all his life, when Liu Zheng was still young, he asked people to ask who farmed well, and Chen Lao was selected for Liu Zheng's special talent collection plan because he could farm a lot more grain than other families every year and have a good harvest in drought seasons.

Then in the exchange with Liu Zheng, I don't know if Liu Zheng turned on a certain switch for him, this farmer, who was originally honest and had never read a book, actually relied on his planting skills all the way to increase the yield of rice, wheat, and sorghum more than once.

Even with Liu Zheng's unremitting efforts, he continued to increase the bounty, and in the past few years, some businessmen did not know where to get a few catties of potatoes and a few corn, and exchanged hundreds of catties of gold from Liu Zheng.

Liu Zheng, who got these treasures, was like a treasure

! I can't wait to export all the few relevant knowledge in my brain! Potatoes

, also called potatoes, are a big killer to solve the famine!

Because this thing is planted with a general yield of 1,000-1,500 catties per mu, of course, this is a good seedling that has been screened by science and technology in later generations, and the yield per mu in this era should be about 800 catties per mu.

But this is not comparable to the existing crops in this era!

Even if it is the No. 37 breeder with the best yield per mu that has been carefully screened by Chen Lao, it is only about 450 catties per mu.

This potato can casually produce 800 catties per mu, which is simply outrageous

! Although the yield per mu is high, no one can stand the fact that the potato is eaten every day

! However, in this era when people can starve to death at any time, it is good to eat some

of them! There are so many messes!

At that time, Liu Zheng gave the potatoes and corn to Chen Lao and asked him to toss, but Liu Zheng told him everything he knew in his head, for fear that he would not know the situation and raise the things to death.

After all, this thing is not only expensive, but also too difficult to go to South America in this era

! The next time I have the opportunity to get seeds, I don't know when!

But fortunately, Chen Lao lived up to expectations, and spent a year to find out the habits of these two crops and record them, which made Liu Zheng feel a lot more at ease.

After several years of exploration, potatoes have been planted in Jizhou, but they are all grown under strict supervision.

After all, this thing can't be leaked out before Liu Zheng's reunification!

However, Liu Zheng took a lot of boiled potatoes and traded them for the people in the state who resisted the tribes in the north to eat, and the price was also very low, almost for free, and Zhao An's dart bureau added a little labor cost and sent it over.

And these potatoes are basically used as war materials, after all, a potato in the pocket, hungry can be eaten at any time, convenient.

"The potatoes are growing quite well. Liu Zheng looked at the prosperity of those leaves in the field and sighed.

"It's all young master, you have the foresight, and you don't hesitate to spend hundreds of catties of gold to buy it, otherwise we wouldn't have such a peaceful and prosperous era in Jizhou!" Liu Zheng stood up at the right time and blew a rainbow fart for Liu Zheng.

Liu Zheng shook his head slightly, sighed, and said: "The potatoes are still too bad, but it's a pity that no one sent sweet potatoes, even if it's a daughter, I'm willing to change it!"

Because the yield per mu of sweet potatoes in later generations started at 6,000 catties! Considering

the reasons for the breeding of the times, the yield per mu of sweet potatoes in this period must at least start at 3,000 catties

! This is four times higher than

that of potatoes! If you just plant this sweet potato in one place, you can manage that people in one place will not starve to death!

Why is there a famine!

It's a pity that Liu Zheng has offered a reward for so many years, but no one has sent sweet potatoes to the door, and he has also sent many people to pass over from the Bering Strait, but after so many years, no one has returned.

Although I have heard Liu Zheng talk about the amazing yield of this sweet potato countless times, every time he hears Liu Zheng mention it, Liu Zheng is secretly surprised in his heart!

What kind of artifact does it have to be to start with a yield of 3,000 catties per mu?

!

Liu Zheng immediately held Chen Lao's hand with both hands, and when he saw this Chen Lao, Liu Zheng remembered an old man in later generations, and in a thousand words, Liu Zheng could only say with the most simple and sincere behavior and feelings: "Chen Lao has worked hard!" Chen Lao's hands

were muddy, and he wanted to pull it back to wipe it, worried about getting dirty Liu Zheng's hand, but he was held by Liu Zheng with one hand, and he couldn't pull it out, and he couldn't help but be a little moved.

Seeing Liu Zheng like this, Xiahoulan looked at Liu Zheng with a little puzzled eyes, and asked with his eyes: What is the situation? Liu Zheng

replied with his eyes: Only Chen Lao

has this treatment! Xiahou Lan's eyes widened and his pupils constricted!

Only Chen Lao has this treatment!
