"Yes! My family is on the edge of Yongzhou, not too far from Chang'an, where many manors and forts have fertile land, and when I was not in the army, I often went to help. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

"Oh? So what are you farming? Corn? ”

"Yes, my helper will grow a lot of corn, which is similar to the Mintun here."

"In that case, do you know how much corn can be produced per acre?"

"My fellow villagers in Mintun said that the land in this capital is good, and the harvest of corn in one acre of land can reach 8 stones, and it is already very good that ordinary land can have 7 stones."

"8 stones...."Cao Pi immediately confirmed the size of the Han Dynasty in his mind, and then began to convert it against the size of later generations:

"Now it is common to use stone as a trading unit, so a clay pot seen in the rice shop before should be the amount of one stone, there are about 25 catties to 30 catties of corn in the clay pot, take the median value of 27 catties, and the yield of eight stones per mu is 216 catties, Ban Gu wrote the "Book of Han" recorded that after Emperor Wu of the Han Dynasty, the general mu system, a large mu is about 465 square meters, 465 square meters produce 216 catties of corn, then 667 square meters produce 309 catties of corn. That is to say, according to the output value of 667 square meters per mu in later generations, the yield of corn per mu in this year is about 309 catties, and it is still a relatively good cultivated land. ”

After getting this result, Cao Pi shook his head secretly, you must know that as early as the beginning of the 21st century, China's second phase of super rice can reach a yield of 800 kilograms per mu, yes, it is kilograms, that is, 1600 catties, which is more than five times the current yield per mu, and it is rice, not corn.

Of course, super rice needs to contain slow-release urea fertilizer, this kind of thing is produced in the digestion process of cattle, as for how to extract it, there is absolutely no such scientific and technological conditions in this era, but as long as hybrid rice can be cultivated, fertilizer is applied according to the amount with cattle harrow and horse harrow, plus hybrid rice has heterosis in growth potential, vitality, fecundity, stress resistance, yield and quality There is no problem in the first phase of getting a yield of 300 kg per mu.

Hey! 300 kilograms is enough to explode the current corn production.

The person in front of me is quite clever and should be able to help me do something, Cao Pi secretly calculated, and asked with a smile: "Do you know how much arable land there is in this legion?" ”

"This.... I'm on an errand in this house, and I really don't know what is going on in the military camp. ”

At this time, the sound of hurried footsteps outside the mansion sounded, and a man in his early forties, wearing a black robe, and wearing a virtuous crown on his head, walked into the mansion with four retinues, and Cao Pi immediately got up and made a big mouth called "uncle".

Ren Jun stepped forward quickly, picked up Cao Pi, and laughed, "Virtuous nephew, how could you come here today." This sentence is the confusion in Ren Jun's heart, this Sikong Gongzi likes swordsmanship, imperial shooting, reading, and what is related to these preferences in this military camp is that there are bows and arrows and horses here, but these two things are military products, even if Sikong Gongzi comes, he can't be deployed at will, if Cao Pi comes for this, it makes Ren Jun a little embarrassed.

Cao Pi smiled and asked instead of answering: "I heard that my uncle likes to play games, and my nephew has been obsessed with this way recently, and he wants to play against his uncle as a pastime." ”

Ren Jun was stunned when he heard this, he really likes to play games, and the game is to play Go. In fact, it's not just him, as long as there are people of some status in this world, they like to play games, after all, this kind of activity that can not only show intelligence but also relax and kill time is still very popular in the Han Dynasty, which lacks entertainment activities. Ma Rong, the first person to study the scriptures now, Zheng Xuan's master, wrote a "Go Fu", in which there is a sentence "The three-foot game is a battle field; Chen Jushi was a soldier, and the two enemies were equal. It can be seen that Go is also a game that shows the talent of the generals.

In these troubled times, the talent of a general is a great talent.

So at this time, Go was more prosperous.

Ren Jun started to play Go before the crown ceremony, the chess power is very strong, even if Cao Cao is not careful, he will be defeated under him, but now he is a pawn farmer Zhonglang general, and he rarely plays against Cao Cao, as for the others, he is really not his opponent Ren Jun, although Cao Pi has a reputation for being young and talented, but he has never heard of who he has played against, and now he suddenly proposed to play against him Ren Jun, which made him feel a little surprised, but he was sure that Cao Pi would not be his opponent. Cao Pi, a young man with a general horn, I'm afraid he hasn't been learning for a long time, maybe the person who taught him to play the game gave him a few wins, and he got carried away, so there is a lot of possibility that he came to practice by himself, so Ren Jun didn't postpone it, and agreed with a smile.

He is Cao Pi's elder, but he doesn't need to let him, and then give him a few fingers after he is done, maybe it will make this nephew respect himself more.

Seeing that Ren Jun agreed, Cao Pi immediately smiled and said, "Just playing chess is too boring, so let's gamble on some gadgets." ”

Ren Jun smiled, and said in his heart that he didn't come to me to practice, but to ask for something, and asked with a smile: "What does my nephew want to bet?" As long as the other party says that he wants horses and bows and arrows, he will immediately refuse, it is a matter of military resources, even if he is sure that he can defeat Cao Pi, he will not take risks, this is his temperament, and it is also the reason why Cao Cao trusts him.

"If the nephew loses, the horse in front of the door will belong to the uncle, if the nephew is lucky to win, just ask my uncle to give me a paddy field, what I ask for is not big, twenty steps is enough, if there is no paddy field in the military tun, but ask my uncle to draw a ten-step open space on the bank of Yingshui for me."

"Huh? This......... It's easy to do, but... Uncle asked a lot, what does the virtuous nephew want to do in the paddy field? Could it be farming? ”

"Nature is farming, but what else can be done?"

"Hehe, it's true, but I don't know if the virtuous nephew still likes farming."

"That's a long story, did my uncle see the man leading the horse in front of the door?"

"Hmm.... He is not very old and has a strong physique. ”

"What does he have in his hands?"

"I didn't notice..."

"Hehe~ Uncle will see it after the game is over."

Cao Pi sold a pass, Ren Jun didn't ask anymore, what he was curious about now was that his nephew seemed to have a bamboo in his chest, even if he started to learn the way of the game from the mother's womb, he wouldn't be his opponent, what could he rely on? While instructing his entourage to fetch the chessboard and chess pieces, he smiled and said, "Virtuous nephew, do you need your uncle to let your son?" ”

This is Ren Jun's biggest reliance on Cao Pi, if he gives too many children, then the other party may win, but just a paddy field, he Ren Jun doesn't care too much, paddy fields, Juntun is there, but the harvest is too poor, and the rice harvested in the paddy field is for the people in the palace to eat, less is less, the big deal is to exchange corn with Yingchuan Chen's grain shop, he doesn't believe that this nephew can always be obsessed with farming, most of it is a whim.

"You don't need your uncle to let your son, please ask your uncle to hold the white son." As soon as these words came out, Ren Jun was stunned, if he didn't let the son, he wouldn't let the son, and he would hold the white son, this is to ask him Ren Jun to take the lead, how much reliance is this? Even if Sikong comes in person, let him take the lead, and if he is not careful, he will fall behind.

"I'm afraid that this nephew has won a lot, and he has the spirit of arrogance, I don't know who has played against him? Most of them are people from the Yingchuan Xun family, Xun Zhongyu was a nephew chair before, this Xun family is really a bit too flattering, today I have to let my nephew lose miserably, otherwise I will be arrogant in the future, and I will suffer a big loss! Ren Jun was thinking about Cao Pi very responsibly in his heart, and he made up his mind to kill Cao Pi for a big defeat, so he didn't postpone it, and after the entourage set up the chessboard on the case, he immediately took the lead in white.
