After the bellies of Erniang and Siniang were "unloaded", the only one who was pregnant in Zhuangzi was Duan Qiniang, who was petite and the youngest.

Counting nine cold days, when it comes to the coldest time of the year, Zhuangzi's lakeside is covered with thin ice, Qi Niang's body is already weak, and she is still pregnant, so cold that her fingers are purple.

The winter in the south, unlike in the north, there is also a fire wall or something to boil, purely by surviving. This year's cold winter was outrageously cold, and the house was ready to burn a charcoal basin, but Li Boyan quickly stopped it.

Not to mention that she wants to live a few more years, even for Duan Qiniang, who is pregnant, this is not conducive to the fetus. Li Boyan misses the air conditioner of later generations, even if there is a "little sun", it is quite moisturizing, but in the era of no electricity, even if it takes the initiative to get in, it is a waste product.

Just when Li Boyan was at a loss, something made his eyes shine.

A large number of rubber tubes left over from the "Great Aunt Period", so the renovation project on Zhuangzi began.

Ancient floor tiles, without cement, were very easy to pry up. Li Boyan asked the mason to coil the rubber pipe like a long snake underground, which made Li Kangda baffled.

In less than a day's work, the balance was placed, the floor tiles were laid again, the rubber pipe outside the house was laid, and the old elders were placed until they were connected to a brick kiln at the back of the Li family's house.

Isn't it easy to burn a brick kiln with glass, boil some hot water?

Li Boyan asked the blacksmith in the Li family's workshop to make a huge funnel and use it to pour hot water into the leather pipe, so that the simple water floor heating could be done.

At first, Li Kangda didn't understand what Li Boyan was going to do with all his efforts, but when the temperature in the room gradually rose, he finally showed a shocked face.

This...... Is that okay too?

In fact, the principle of this kind of floor heating is very simple, that is, through the heat transfer of heat radiation and convection, the water temperature in the leather tube is transmitted to the room, so that it is the same as turning on the air conditioner.

Li Kangda took off his heavy cotton clothes and said with a smile: "In this room, it is enough to wear a thin shirt, and the cotton jacket is sweaty." ”

Duan Qi Niang's face also became a little ruddy, and she kept saying that Da Lang was so smart, which made Li Boyan a little embarrassed. was called Da Lang Da Lang by a woman who was about the same age as Qiu Jinmei, and I always felt a little uncomfortable.

In fact, this kind of floor heating almost appeared in the late Ming Dynasty, but they did not have a heat-resistant rubber pipe like Li Boyan, and they completely built a flue underground and used smoke to conduct heat, but such an extravagant heating method was only affordable for the emperor.

This rubber pipe is difficult to get, so except for a few rooms on the Zhuangzi, Li Boyan has no way to get another one, and it happens to be the New Year, so he simply nests in the Zhuangzi and gets warmer.

Towards the end of the year, the stewards and shopkeepers of various workshops stepped up their accounts, and Liu Feng also rushed back to Hengzhou, after all, he was also Liu Ji's young master, and he always worked for Li Boyan in heaven and earth, and it was purely a free volunteer, which was unreasonable. Li Boyan paid 1,000 yuan in advance for Liu Qiushan to take back Hengzhou, and in the past six months, Liu Ji of Yongzhou has provided him with sufficient capital chains, and there is also the credit of the Liu family, so naturally he can't be treated badly.

The money shopkeeper has now been transferred to the Taobao hypermarket, and four or five sub-shopkeepers have been recruited, and Liu Yu will take care of the heaven and earth, but there is nothing wrong with it. Before Li Boyan went to Suzhou, he decided to vacate the second floor and expand Liu Ji. Today's Liu Ji, the capacity of the two-story building, is much more than the Yuebo Building, the first floor is the same as a large canteen, the second floor is renovated, each one is extraordinarily chic, calligraphy, painting, wood carving, glazed porcelain, extravagant.

"Boom, ......"

"What's wrong with the gentleman?" When Li Boyan saw Zhao Ruyu in person, he went out to greet him, and Ye Shi behind him also got off the carriage, "If there is anything wrong with Mr., order Xiaotong to pass on a word, I will come over." ”

Zhao Ru smiled foolishly: "I know that you are at the end of the year, busy with business, I and Zhengzheng are idlers after all, and it doesn't take much time to come to Zhuangzi...... Yo! ”

"I'm going to be a good guy!"

As soon as they walked into the house, Zhao Ruyu and Ye Shi were like ghosts, trembling all over.

"How many charcoal pots do you have in this house, so warm."

Uncle Yan looked around and muttered, "I don't see smoke, I don't see a charcoal basin, what kind of new thing is Dalang?" ”

The two of them didn't stay in the house for long, and then they took off their coats a little hotly.

Li Boyan asked people to bring tea over, and said with a smile: "Mr. will know when you touch this floor tile." ”

Uncle rubbed the back of his hand and exclaimed, "It's hot!" This...... Da Lang, let's discuss something, you can also install this thing in that Beiyuan for you. ”

Li Boyan smiled bitterly: "I'm afraid Mr. Ye can't afford this thing." Facing Uncle Rub who was only willing to spend forty yuan on a boat, Li Boyan thought to himself, you are not a big belly, and you are so delicate that you need floor heating? Carry it yourself.

Uncle Rub leaned back in the chair with some disdain and said, "Who is rare." A certain burned his own charcoal basin to go. ”

"Mr. Ye wants to burn a charcoal pot, remember to open some windows, otherwise you will be in trouble if you die."

"Don't worry about it." Ye Shi took the tea, took a sip, and replied sourly.

Zhao Ruyu also shook his head and smiled when he saw the two people who were about to pinch up when they met, "Let's get down to business." I came here this time because of Bo Chong's business. ”

"Fan Gong? What happened to Fan Gong? ”

Uncle Rub said unabashedly: "Fan Bochong is going to be developed!" ”

"Oh?" Li Boyan raised his eyebrows, Li Boyan knew about the changes in Yongzhou this year, but he didn't expect to be alarmed so quickly.

Zhao Ruyu said: "Late last night, Bo Chong came over in person and told me that he was going to Beijing to face the saint on the same day, and asked me what I should pay attention to. ”

"What did the gentleman say?"

Zhao Ruyu said slowly: "Don't be arrogant or impatient, report truthfully." Don't mention the obscurity, it is different from Han Jiefu. ”

In just two sentences, the golden mean is vividly displayed.

Li Boyan nodded and said, "If Fan Gongzhen does what you say, I'm afraid it won't be difficult to enter the center." ”

Ye Shi saw that Li Boyan was not very excited, so he said: "Looking at Da Lang's face, it seems that Fan Gong has entered the center, as if you are very unhappy?" A certain told you, Fan Gong has entered the center, and in the future, we will implement new learning, so that we will have a way to speak, otherwise how easy do you think it is to establish a school? This time the party ban, whether it is Cheng Zhu Lixue, Lu's Xinxue or Yongjia School, they have all been wiped out by Han Jiefu, the king of the eight calves, and those who are not used by him have all fallen off the horse, if there is no one in the court, you, me, and Zhao Xianggong are not enough for him Han Jiefu. ”

Li Boyan sighed lightly and muttered: "The truth is such a truth, but the student feels that he went earlier." ”
