In July of the twelfth year of Zhenguan, Qin Qiong, the Duke of the Tang Dynasty, Uncle Qin.

When a minister passed away, the dynasty was naturally shaken.

Although Qin Qiong has basically no sense of existence in recent years, he is the founding father after all, so Emperor Li Shimin personally issued an order to posthumously present Qin Shubao as the governor of Xuzhou and accompany him to the Zhaoling Tomb; In addition, he also deliberately asked people to build stones in front of Qin Qiong's tomb to highlight Qin Shubao's military exploits. Even Qin Huaidao, a fourteen-year-old little boy, was named a thousand cows by Li Shimin - this is a senior Praetorian Guard officer who is in charge of the imperial sword "Thousand Cow Knife", and the emperor Li Yuan also did an errand back then!

Regarding Qin Shubao's death, except for a little depression, Li Yuanjia didn't feel much about it.

The home-brewed liquor drank Qin Shubao to death...... Ahem, it should be said that after getting the home-brewed spirits, Qin Shubao, who originally had one breath left, died, what does this have to do with him? He had already warned Qin Huaidao, they didn't believe it, what could Li Yuanjia do?

And what surprised Li Yuanjia a little was that when he went to attend the funeral of Duke Yiguo in person, not only did Qin Huaidao see him respectfully, without any resentful expression, and even Qin Qiong quoted the liquor of Han Wangfu, and no one seemed to mention it!

It's as if it never happened.

"So, I'm thinking too much?"

After returning to the palace, Li Yuanjia exhaled softly. He was not afraid that this matter would cause him any trouble, but he was afraid of being included in the books written by some boring people, after all, the name Qin Shubao was too famous in later generations......

Life returned to peace, Li Yuanjia taught Fang Fengzhu mathematics every day, and occasionally taught classes to the children of Wangfu Primary School, and his life was still leisurely.

However, within a few days, Li Yuanjia received a piece of good news.

"In other words, this year's cotton harvest is quite a lot??"

Looking at Sun Zhan, who was excited, Li Yuanjia raised his eyebrows.

"Yes, King."

Nodding vigorously, Sun Zhan said respectfully: "This year, we planted twenty acres and harvested a total of seven hundred and sixteen catties of cotton, with an average of thirty-five .8 catties per mu!" Only 69 catties of cotton were harvested from the three acres planted last year, with an average of only 23 catties per mu...... Therefore, if the yield per mu is calculated, this year's increase is 55.6 percent compared with last year! ”

"Oh? Not bad! ”

After listening to Sun Zhan's answer, Li Yuanjia's eyes suddenly lit up, and he nodded in surprise.

Compared to last year, this year can be regarded as a "bumper harvest", right?

He was pleasantly surprised not only that the yield per mu of cotton had increased by more than half, but also that Sun Zhan had just said those words! The output data is accurate to the catty, and even the increase in the proportion is accurate to the figure of 55.6 percent, which is more than the increase in cotton production and makes Li Yuanjia happy.

So after a pause, Li Yuanjia smiled approvingly: "Sun Zhan, it seems that you usually not only manage the cotton fields, but also this math has not fallen behind!" Not bad, very good! ”

“…… King Xie. ”

After swallowing and spitting, Sun Zhan hurriedly bent down to thank Li Yuanjia for his compliment.

These things are the result of his efforts for an unknown amount of time. Not only are the books given by the king already a lot older than he has read, but when he is idle on weekdays, Sun Zhan also likes to go to the papermaking workshop and consult his teacher Wang Pu, who has already been reborn over time.

"Alright, get up."

After waving his hand to let Sun Zhan get up, Li Yuanjia looked at the kid in front of him, and his heart became more and more satisfied.

Among the five people back then, Sun Zhan was definitely not the smartest, and the impression he left on him was that he was honest and willing to work, otherwise he would not have sent him to serve those precious cotton seeds. But now it seems that this kid is really the one who works hardest!

So after a pause, Li Yuanjia said happily: "You must handle the cotton you harvest carefully, and the seeds must be all protected!" In other words, this time, these seeds should be able to fill the 100 acres of land, right? ”

After thinking for a while, Sun Zhan nodded seriously: "Yes, King, even if you plant it densely, these seeds are enough!" ”

"Very good, plant it all for me next year!"

With a wave of his hand, Li Yuanjia was full of pride!

The technology of this year is really not good, and the germination rate and survival rate of cotton seeds are not satisfactory, so even if the seeds harvested from 20 acres of cotton are actually not much. But it doesn't matter, with Sun Zhan carefully serving those lands here, Li Yuanjia is very relieved, and he is sure that sooner or later he will be able to save enough cotton seeds to plant Datang!

At that time, ordinary people will have better protection from the cold in winter.

Looking at the yearning look on the king's face, Sun Zhan felt a little strange in his heart, but he didn't dare to open his mouth, just stood there quietly and waited for orders.

And after a while, Sun Peng, who came back to his senses, spoke: "Sun Zhan, after the seeds are saved, pack up the more than 700 catties of cotton as soon as possible, and then send them to the palace, this king is of great use...... You've done a good job this year, and you'll find a housekeeper to get a reward later! ”

"Yes, thank you, King!"

After listening to the king's words, Sun Zhan was immediately overjoyed, and at the same time secretly relieved.

It is actually very troublesome to deal with the cotton that is picked, especially when every seed is quite precious, Sun Zhan and they can only pick it out of the cotton one by one by hand, which is time-consuming and laborious. If it weren't for that, Sun Zhan and the others would have used some tools to remove the seeds.

But to be able to get Li Yuanjia's praise, and there are still ten rewards to take, even if it is hard, Sun Zhan doesn't feel it at this time.

It's just that before Sun Zhan could be happy for a while, Li Yuanjia suddenly asked again: "What about the spinning wheel?" How have you improved? ”

"Back to the king's words, still, still working hard."

With a chuckle in his heart, Sun Zhan quickly put away the smile on his face and replied, "Compared with what I did last time, I have ...... recently And not much progress. ”

The spinning wheel used to spin cotton was made by the craftsmen under Sun Zhan at the beginning of the year, after all, it is not too difficult to spin cotton into threads except for seeds, and there are reeling wheels for reference. But after seeing it, the king said that it was too bulky and heavy, and the requirements must be more light and convenient, so Sun Zhan could only let people continue to improve.

Li Yuanjia was not surprised by this, just nodded and said: "Don't worry, anyway, there is not much cotton production now, you just take your time...... Alright, that's all for today, you go down first. ”

"Yes, my lord."

After saluting respectfully, Sun Zhan retreated lightly.

After Sun Zhan left, Li Yuanjia stood up from the chair, and while spinning around the room, he pondered with a smile: "Seven hundred catties of cotton, it should be able to make a lot of things, right?" Tsk, this time, but think carefully about how to maximize their value......"
