The results of the statistics soon reached everyone's ears, and the better fields, which were taken care of more carefully, finally got the results of 10,000 catties per mu, and the worse fields also had 8,000 catties.

Those who didn't grow sweet potatoes regretted it to death at the moment.

The old farmer who got the harvest grinned and looked at the sweet potatoes as if they were gold.

The officials who received the order also rushed to these fields where sweet potatoes were planted, and informed them: "You only need to pay 20% to come up and make seeds." ”

The fields were filled with ecstasy.

Xu Jiao was lying in the room thinking about the task, and Zhu Qing looked at the princess as if she was in a daze, got up and went to the small kitchen to cut a plate of fruit.

Zhu Qing put the fruit on the table next to Xu Jiao, and called her lightly: "Princess, eat some fruit." ”

Xu Jiao came back to her senses and looked at Zhu Qing.

Zhu Qing is the most stable maid by her side, although she doesn't talk much, but she is the smartest and most considerate.

Xu Jiao asked Zhu Qing: "How old did you enter the palace?" Do you remember what happened before entering the palace? ”

When Zhu Qing heard the question, he was distracted for a while, and then smiled with relief: "I was sold by my father and mother when I was six years old, and I just happened to meet the housekeeper who bought the little palace maid in the palace. ”

Zhu Qing paused for a moment, and then said again: "I am good-looking, and the people in the palace did not take a fancy to other girls in the village, so they fell in love with me. My family was so poor, I just remember that I had many brothers and sisters, and if they sold me, they would have money to buy food to eat. ”

Xu Jiao regretted that she asked her this question and touched on her sad past.

Seeing the princess's expression, Zhu Qing probably guessed what she was thinking, and comforted: "It's nothing, the palace is a good place to go, if I don't come in, I may have starved to death." ”

For ordinary people, being alive is the biggest goal.

Xu Jiao thought of the people who froze to death every winter here, and a very strange feeling welled up in her heart, which made her extremely uncomfortable.

She shouldn't just think of this place as a place to complete tasks, at this moment, she really hopes that the people will live, live well, and live happily.

I don't know when the system mall will be updated, Xu Jiao clicked in to take a look and see if there is anything that can solve the problem.

A commodity appeared in front of her eyes, something she was not familiar with, but she had heard of it.

The system upgrade plate fire kang simple perfect version, the price is 300 task points.

Xu Jiao's eyes lit up, this year's harvest is good, the people don't have thick clothes in winter, and they won't go out if they are not hungry.

The people sat on the kang and ate and stored grain, so it must not be a problem to survive this winter.

She has been living in the south in modern times and has never seen this thing, but when she was in college, she had a roommate from the north, and her roommate gave her science popularization, saying that sometimes she would be burned awake when she slept on it.

Xu Jiao thought about it, this is indeed the most suitable at present, and when she carries this winter, she will arrange the cotton.

"Go and call Ding Rong and them over to me." Xu Jiao instructed Zhu Qing.

Zhu Qing went out of the princess's dormitory and walked through the cloister to the craftsman's house in the front yard.

Xu Jiao's princess's mansion is not to mention anything else, it covers an area wide enough, Xu Jiao directly asked people to set aside a piece of land in the front yard to build a craftsman house larger than the palace for Ding Rong's group of craftsmen to live.

Zhu Qing walked for a quarter of an hour before arriving at the craftsman's house, and Ding Rong saw Zhu Qing from a distance and came up to greet him.

"Why is Sister Zhuqing here, but what does the princess command?" Ding Rong asked with a smile.

Zhu Qing nodded and spoke: "Don't call me sister, I'm younger than you, just call my name." Go ahead, princess waiting. ”

Ding Rong nodded and called everyone to follow Zhu Qing.

Xu Jiao spent 300 task points to redeem this item, which is still a booklet, but it is mostly blueprints and less text.

As soon as Ding Rong and the others came, Xu Jiao threw things at them.

"Research and research, and put it on my princess's mansion first." Xu Jiao turned sideways to fork the fruit to eat, rejecting Zhuqing's intention to feed it.

The drawings were so detailed that they didn't seem to have a hard time at all.

"Princess, where did this drawing come from? I've never seen it before. Ding Rong said sincerely, this is not a boast, they think these drawings and ideas are simply amazing.

"It's right if you haven't seen it, hurry up and get ready, get it for me." Xu Jiao ignored his question.

Ding Rong and the others immediately prepared the materials, but in fact, there was nothing to prepare, because the raw materials were just soil, so the person who designed this was simply a whimsical idea and turned waste into treasure.

In less than an hour, Ding Rong and the others were ready.

"When it's dry, the princess will be ready to use it." Ding Rong wiped the sweat on his head, although this thing is simple, it is made for the princess, he has to show twelve points of care and do it perfectly.

In the following day, Ding Rong and others shuttled through the princess's mansion and set up a kang for each person's house.

Their techniques are becoming more and more proficient, and their speed is getting faster and faster, and often a group of people can make one in the time of a pillar of incense.

Xu Jiao inspected the things they had made, and felt that they had done a very good job, so she immediately took them and walked towards the Taishou Mansion.

Zhong Xiang Taishou was having dinner, and the sweet potato harvest was bumper, even if it was only two percent, it was not a small amount, and he was in a good mood in the past two days, and his smile never went down from his face.

This time, when he heard that the princess had come to the door, he immediately got up and went out to meet him.

"The princess is here, is there something wrong?" Zhong Xiang asked curiously.

Xu Jiao nodded and did not deny it: "You go and gather all the craftsmen in the city, I have something to order." ”

Zhong Xiang Taishou didn't ask the reason, and immediately ordered his subordinates to do it, and the craftsmen had a record of craftsmanship in the government, and it was not complicated to summon them.

It's just that Zhongxiang City is too big, even if the little official goes on horseback, it will be dark when all the craftsmen gather.

Xu Jiao instructed people to light torches and light lamps to illuminate the courtyard of the Taishou Mansion as bright as day, and the craftsmen gathered were all crowded in the courtyard, but they still couldn't squeeze in.

"Don't be in a hurry, then come in batches, and the craftsmen who can't get in will wait outside." Xu Jiao instructed, and someone immediately organized craftsmen to divide into batches, and the crowded courtyard instantly became more spacious.

Ding Rong and others set up a fire kang under Xu Jiao's instructions, and explained while operating, this thing is not complicated, most of the craftsmen present understood it as soon as they heard it, and they also instantly understood the usefulness of this thing, and instantly became ecstatic, this can solve the problem of severe cold in winter!

Xu Jiao saw it in her eyes and didn't speak.

The craftsmen learned this technique in four batches, and Xu Jiao stood in front of everyone and spoke: "In the name of the government, you go to make a fire kang for every household in the city, and there can be no omission, the government will pay you, and you must not charge the people a penny." ”

These craftsmen have all been registered in the Taishou Mansion, and Xu Jiao is sure that he can control this group of people.

The craftsmen were ready to work for the princess for free, not to mention that such secret techniques had been taught to them for free, and they were already very grateful, but they didn't expect to be paid.

"We all know that this thing is for the benefit of the people, and we will do our best to do it well, please rest assured, Your Royal Highness the Princess." The craftsmen all nodded in agreement.
