This is a farmer's house, and this is a vacant room in his family. Song Yunuan bought the room, and then asked the farmer to help her burn the kang. The price was relatively high, so the farmer's family was very happy.

After all, it’s hard to work in this winter, and nothing can be grown in the fields. I have nothing to do except stay at home every day.

Song Yunuan compared the drawings while communicating with Cuihua.

However, Cuihua is just a beast, and the drawings it can give are not drawn by it itself. Those are goods from various plane malls, and it can't give Song Yunuan any advice at all.

Fortunately, the farmer and Song Yunuan were the three cobblers who outdid Zhuge Liang and finally made the prototype of the kang.

Suddenly there was a noise outside, and the man who was in charge of the family said, "Girl, wait a minute, I'm going to see what's going on outside."

Song Yunuan nodded. She compared the drawings countless times and used a pen to calculate countless times to confirm again and again that there should be no problem.

But even so, I still can’t put it into practice for a while.

However, judging from the current progress, the results should be available within a week.

Song Yunuan put the drawing away, and then said to the woman: "This thing is like this for now, I will come back tomorrow."

"Okay girl, we won't mess around."

As soon as the woman finished speaking, a big man's loud voice came from outside, "Girl, someone is looking for you."

The only "girl" at the moment is Song Yunuan.

Song Yunuan is a little strange, who else can look for her at this time?

Moreover, she knew about it and didn’t tell anyone except Lan Xing when she went out. Could it be that Lan Xing told others?

Even if other people asked, Blue Star would only give a general idea, and it was impossible to be precise to a certain place.

Song Yunuan walked out and bumped into someone when she opened the door.

"Why are you so reckless?" Xie Nanchu put his arms around Song Yunuan's waist and helped him stand up.

"Xie Nanchu?" Song Yunuan rubbed her forehead and said, "How did you know I was here?"

This question seems to be in vain. Lan Xing is Xie Nanchu’s person, so it’s not strange at all for him to know that he is here.

Thinking of this, Song Yunuan couldn't help but glare at Lan Xing behind her.

Lan Xing's face was expressionless. She knew that this was Song Yunuan's acquiescence, otherwise she would not spread the news about Song Yunuan randomly.

"Is the matter done?" Xie Nanchu let go and asked.

Song Yunuan nodded and said: "It's over for now, but there will probably be news about what needs to be done in five or six days."

"Now that the matter is done, let's go." Xie Nanchu held Song Yunuan's hand and said softly.

Song Yunuan nodded and said to the big man, "I'll come back tomorrow."

The big man sent the people away in fear.

Seeing him like this, the woman felt confused. She waited until everyone had gone away before asking, "What are you doing?"

The big man slapped his forehead and said with suppressed ecstasy: "Wan Niang, you don't know, that person is the regent!"

Wan Niang was suspicious and said, "Are you stupid?"

"You're not stupid, that person is really the regent. The current regent was once the eldest son of Duke Rongguo, and his name is Xie Nanchu!"

Wan Niang looked at him suspiciously and said, "No way, that man just now was just a young man, he didn't look like he had grown up yet."

The man looked at his wife with disgust and said, "You don't understand, the regent is only eighteen years old, that is, he looks like a teenager."

"Really?" Wan Niang couldn't believe it.

"Then the woman who is so close to the regent is..." Wan Niang couldn't help but cover her mouth.

The big man was so excited that he almost fainted. He said: "It is rumored that the regent is very passionate about Princess Yujia. Even if the engagement is broken off, he will be re-engaged. Moreover, it is rumored that Princess Yujia really likes to do some weird things.

And it is said that she looks very sweet and cute.”

"Right, right!" Wan Niang was also very excited.

"Oh my God, it's like the ancestors are smoking. This must be a good choice for the ancestral tomb! No, I must go and burn a few more sticks of incense for my ancestors."

Xie Nanchu guessed that his identity was exposed, but he didn't mind.

This is not far from the capital, and exposure is normal. That family is just an ordinary farmer, and nothing will happen to them.

Song Yunuan also came here on a bicycle. After returning, Song Yunuan was almost frozen.

She gathered around the stove and kept rubbing her hands.

"Why are you going to the outskirts of the city in such a cold weather?" Xie Nanchu asked, a little blamed and a little distressed.

He took the ginger soup from Lan Xing and handed it to Song Yunuan.

Song Yunuan caught it and sighed with satisfaction.

"Trying on the kang." Song Yunuan trembled, but it was still too cold.

"Kang?"

"Well, the weather is too cold. It's several degrees colder than last year." Song Yunuan slowly moved towards Xie Nanchu.

When Xie Nan saw her for the first time, he sighed softly and stretched out his hands to take her over.

"This rich family can still burn charcoal to keep warm, but the poor people don't know how many people will freeze to death." Song Yunuan snuggled deeper and deeper into Xie Nanchu's arms.

The body temperature of boys is generally much higher than that of girls, which is an important reason why Song Yunuan pressed forward so eagerly.

Xie Nanchu said: "Indeed, if there is no good solution, I don't know how many people will die this winter."

He also sighed, a little worried.

"That's why I want to build that kang. With that kang, the mortality rate this winter will definitely be reduced a lot."

Although this is also a task given by Cuihua, I have to say that this is a good idea.

But having said that, without the drawings provided by Cuihua, she might not be able to work it out.

She only had a rough understanding of the so-called kang. The memories of modern times in her mind belonged to the south, and there was no information about the north.

Fortunately, the principle of this kang is not particularly difficult, otherwise, she would not be able to do it.

"Can you tell me about the kang?"

Song Yunuan was reluctant to come out of Xie Nanchu's arms. She said: "Actually, it is similar to the floor heating we have now. It's just that people are cooking on the outside of the kang, and it's empty inside. People over there can sleep on it."

Although Song Yunuan's explanation was very vague, Xie Nanchu had a smart mind, and with the prototype he saw today, he already had a rough idea in his mind.

"It is indeed a good way to kill two birds with one stone. People have to make fire to cook every day, and the remaining heat is not wasted. It is a good way." Xie Nanchu's eyes were bright. He wanted to publicize this method, so this winter would not be a problem.

.

"The kang is a good thing, but what about your greenhouse?"

Song Yunuan was a little surprised, "You know?" She raised her head from Xie Nanchu's arms.
