"Hmm~! This mutton is so exciting to eat! How can good meat be without good wine? Xiaoxuan, let someone bring the wine! Your father, your grandfather, and I will have a good drink~!"

Others said that Cheng Yaojin came out of nowhere, but Li Zexuan was halfway through eating hot pot today when he ate Cheng Yaojin!

The old goblin came here originally intending to see how the Li family's greenhouse vegetables were growing, because his family's Zhuangzi and Qin Qiong's family's Zhuangzi have recently begun to introduce greenhouse vegetable cultivation technology.

The result! The veteran Greenhouse Vegetables didn't even take a look. As soon as he entered the house, his eyes were fixed on the mutton, fish and dipping sauces on the table.

After spending so much time with Cheng Yaojin, how could Li Zexuan not understand what this old guy was thinking? So he didn’t say anything and directly invited Cheng Yaojin to eat hot pot together! Anyway, with the identity of this old guy, it would get dark soon.

There is no need to worry about Wu Hou arresting him because of the curfew!

Cheng Yaojin gave Li Zexuan an approving look, then sat down and started eating together without ceremony.

As the saying goes, eat a big piece of meat and drink a big bowl of wine. After eating for a while, Cheng Yaojin felt a little uncomfortable, so he yelled for Li Zexuan to get the wine!

Li Zexuan had no choice but to let Sanbao go to the wine cellar to get a jar of immortal wine.

After the wine came on the scene, the atmosphere became more lively. Cheng Yaojin was cheerful by nature, and he had become quite familiar with Father Li over the past year. Ye Guozhong had been in a high position for a long time and was well-informed. The three of them still had many common topics. Suddenly,

It’s so lively to drink and drink together!

Li Zexuan felt that Cheng Yaojin's wine was not very good, and he only wanted to eat hot pot, not drink, so he did not join them. Lan'er, Mrs. Li, and Mrs. Ye also enjoyed the meal.

What a joy!

After drinking and eating, Cheng Yaojin burped and returned with a satisfied smell of alcohol. Before leaving, the old guy swayed and said to Li Zexuan: "Hiccup~! Xiaoxuan~! You

This hot pot at home, bur~, is so... so delicious! I will send my cook over later, bur~, you... you have to be taught... teach him! I haven't eaten in a long time

So full, burp~, I feel so good after drinking!"

The old guy had completely forgotten his original intention of coming to Li's house, but he only remembered the hot pot thing. It has to be said that in the absence of a fight, food and drink is Lao Cheng's biggest pursuit now!

………………………

On the second day, near noon, Li Mansion.

"Feiji, please send these drawings to the workshop and give them to Uncle Fu, and let him build them in the next two days!"

Li Zexuan called Pang Feiji, took out two drawings, handed them over, and gave instructions.

"Yes! Mr. Hou~!"

Pang Feiji took the order and left.

Li Zexuan asked someone to carry a coal stove and a basket of briquettes onto the carriage. The coal was still burning in the stove. Then he rode the carriage towards the palace. He wanted to see Li Er.

As for the drawings he just gave to Pang Feiji, they were drawings of radiators and heating pipes that he had just drawn in the morning. The structures were quite simple, and he had already measured the dimensions in the morning. The dimensions of the houses in Yunshan Villa were not what they were at the time.

The drawings of other courtyards were all drawn by him, so there was no need to measure them.

Li Zexuan plans to install self-made heating in his house and Yunshan Villa at the same time.

Anyway, now we have honeycomb briquettes and coal stoves. Just set up a pot and arrange some pipes, and it's basically OK!

He modeled this on some homemade heaters in the countryside in his previous life. The principle is also very simple:

A large boiler for boiling water. The furnace is double-layered, with the top and bottom closed. The top is connected to a steel pipe to connect the water layer from the flue to the heating water supply. This point is the lowest point of the water supply pipe, and the heating end is set to the highest point.

Exhaust valve, slope 1%;

The bottom is flat to connect to the heating return water, and then the water return pipe is connected to the water supply pipe next to the furnace. The height exceeds the highest point of the water supply pipe, and then a water supply tank is installed. The return pipe next to the furnace is the lowest point and the highest point of the heating section has a slope of 1%;

The water in the furnace is heated and turns into steam, which rises and dissipates heat through the water supply pipe to the highest point and becomes a mixture of hot water and steam. After the hot water enters the radiator and is dissipated, the temperature decreases, the density increases and the volume becomes smaller. It enters the return water pipe and enters the boiler.

This forms a circular loop.

The slope of the water pipe of the self-made heater is very important. An inverted slope will cause no heat. The water layer in the furnace tank should be thin, 1-3 mm is enough, because a thick water layer will consume coal. The exhaust valve at the high point must be open, otherwise the whole system will be closed.

, there will be an explosion!

The reason why Li Zexuan started heating now is mainly because there was no briquettes or coal stoves before. It was very inconvenient to boil water because the continuous burning ability of charcoal is far inferior to that of briquettes! Now that briquettes and coal stoves are available,

Then of course he should quickly install the heating in his home!

.…………………………………………

In the palace, just after the morning court, Li Er returned to the Lizheng Palace in Xiyuan, because there were charcoal pots and heaters here!

Although he is a horse emperor and has martial arts skills, he is far from being immune to cold and heat like a martial arts master. Even in this kind of weather, he will feel cold!

Li Er had just spoken to Empress Changsun for a short time in Lizheng Hall when a servant from Huangmen came to report.

"Your Majesty, Marquis Yong'an wants to see you!"

Li Er was stunned for a moment, then laughed out loud, "Oh? When will this kid take the initiative to come to me? Did he tell me why?"

Since Li Zexuan entered the officialdom, most of the time he entered the palace only after Li Er summoned him. It is extremely rare for him to take the initiative to enter the palace like today!

"Back to Your Majesty, Marquis Yong'an said that he came to offer a treasure!"

The waiter replied cautiously.

"Presenting treasures? Haha~! The new things today are really happening one after another! Let him wait at the Manna Hall first, I will be here soon!"

Li Er's curiosity aroused, and he didn't care about the freezing weather outside. He put on his fox fur coat and prepared to go to Ganlu Hall to meet Li Zexuan.

After all, this is the harem, and Li Zexuan is an adult and married normal man, so of course he cannot be allowed to come here! If it had been at the beginning of the year when Li Zexuan was not married, Li Er might have met him in the harem, but now it is absolutely impossible.

No way.

"Your Majesty, I also want to see what kind of treasure Marquis Yong'an is offering. I wonder if I can go with your Majesty?"

But Queen Changsun was also interested, and she asked Li Er.

"Haha! Since Maid Guanyin is interested, let's go with you! But it's very cold outside, so Maid Guanyin, you need to put on more clothes!"

Li Er laughed and agreed readily.

"Thank you for your concern, Your Majesty, I will spare you the trouble!"

Empress Changsun felt warm in her heart, and the palace maid put a mink fur jacket on her, and then the couple went out!
Chapter completed!
