Otaku Engineer in Great Tang Dynasty Chapter 1038: Presenting treasures!

"Um~! This mutton is delicious! How can there be good wine without good meat? Xiaoxuan, let people get the wine! I have a good drink with your father and your grandfather~!"

Others say that Cheng Yaojin was killed halfway through, but Li Zexuan was half eating hot pot today and got Cheng Yaojin!

The old fairy came here to see how Li’s greenhouse vegetables look like, because his family’s Zhuangzi and Qin Qiong’s family have recently introduced greenhouse vegetable cultivation techniques.

The result! The old vegetable in the greenhouse did not even look at it. As soon as he entered the house, his eyes were fixed on the lamb, fish and dipping sauce on the table.

With Cheng Yaojin for so long, how could Li Zexuan not understand the old guy's mind? So he didn't say anything, and directly invited Cheng Yaojin to have hot pot with him! Anyway, as this old guy, there is no need to worry about Wuhou arresting him because of the curfew when it gets dark for a while!

Cheng Yaojin gave Li Zexuan an approving look, then sat down and ate together unceremoniously.

As the saying goes, eating large pieces of meat, drinking from a large bowl, and eating for a while, Cheng Yaojin felt a little awkward, so he shouted for Li Zexuan to get the wine!

Li Zexuan had no choice but to let the Three Treasures go to the wine cellar to hold a jar of gods drunk.

The atmosphere became more lively after the wine came on. Cheng Yaojin has a refreshing nature, and he has been familiar with Daddy Li over the past year. Ye Guozhong has been in a high position for a long time, and he is also well-informed. The three of them still have common topics. For a while, the coveting is intertwined, so lively!

Li Zexuan felt that Cheng Yaojin’s wines were not good, and he only wanted to eat hot pot, he didn’t want to drink too much, so he didn’t mix with them, and he also ate with Lan Er, Mrs. Li, and Mrs. Ye. It's so fun!

After drinking, eating and drinking, Cheng Yaojin returned home with a burp and drunken satisfaction. When he left, the old guy swayed and did not forget to confess to Li Zexuan: "Hiccup~! Xiaoxuan! ~! This hot pot in your house, hiccup~, it's so... so delicious! I will send my cook over here, hiccup~, you...you have to be taught...teach him! My old Cheng It’s been a long time since I’ve eaten so full, hiccup~, drinking so much!"

The old guy had completely forgotten his original intention of coming to the Li family, but he only remembered the hot pot thing. I have to say that in the absence of war, appetite is Lao Cheng’s greatest pursuit now. what!

……………………………

On the second day, near noon, Li Mansion.

"Feiji, you send these drawings to the workshop and give them to Fubo, let him make them in two days!"

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

"Yes! Lord Hou~!"

Pang Feiji led the way.

Li Zexuan let someone lift a coal stove and a basket of briquettes onto the carriage. Coal was still burning in the coal stove. Then he rode the carriage towards the palace and he was going to see Li Er.

As for the drawings that Pang Feiji just gave to Pang Feiji, they are the radiator and heating pipe drawings he just drew in the morning. The structure is quite simple. He has already measured the size in the morning, and the size of the house on the Yunshan Courtyard At the beginning, the drawings of the other courtyard were all drawn by him, so naturally there is no need to measure them.

Li Zexuan plans to install self-made heating for the mansion and Yunshan Courtyard.

Anyway, now there are briquettes and coal stoves. Just set up a pot and drain some pipes. It's basically OK!

He made this model of some homemade heating in the countryside in his previous life. The principle is also very simple:

A large water-heating boiler, the furnace is double-layered, the top and bottom are closed, the top is connected with a steel pipe and a 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 the exhaust valve at the highest point with a gradient of one percent;

The bottom is flat to connect the heating return water, and then the water return pipe is connected to the water supply pipe next to the furnace, and the height is higher than the highest point of the water supply pipe, and then a water supply tank is set up.

After heating, the water in the furnace tank becomes steam rising, and it becomes a mixture of hot water and steam through the water supply pipe to the highest point. After the hot water enters the radiator, the temperature decreases, the density increases, and the volume becomes smaller. Enter the boiler, thus forming a circulation loop.

The **** of the water pipe of the self-made heating system is very important. The inverted **** will cause no heat. The water layer of the furnace should be thin, 1-3 mm. Because the water layer is thick, it will cost coal, and the high-point exhaust valve must be open, otherwise If the whole system is closed, it will explode!

The reason why Li Zexuan has only started heating up now is mainly because there was no coal briquettes and no coal stove before. It is inconvenient to boil water, because the continuous burning ability of charcoal is far less than that of briquettes! Now that he has created briquettes and coal stoves, of course he must quickly install the heating at home!

.……………………………………

The imperial palace, just after the early morning, Li Er returned to the Xiyuan Lizheng Hall, because there are charcoal basins and heaters!

Although he is the emperor of horses, he also has martial arts, but he is still far from the point where the master of martial arts can not invade the cold and heat~ IndoMTL.com~ This kind of weather, he will also feel cold!

Li Er had just spoken with the Empress Changsun in Lizhengdian for a short while, and the Huangmen servant came to report it

"Your Majesty, see you Yonganhou!"

Li Eryi was taken aback, and then laughed out, "Oh? When will this kid take the initiative to come to me? What does he say?"

Since Li Zexuan entered officialdom, most of them were only when Li Er summoned him to enter the palace. It is extremely rare to take the initiative to enter the palace like today!

"His Majesty, Yonganhou said that he is here to offer treasures!"

The waiter replied carefully.

"Presenting treasures? Ha~! This new thing is really one after another today! Let him wait in the Temple of Ganlu first, and I will come soon!"

Li Er was very curious, and he didn't care that it was freezing outside, so he put on a fox fur coat and prepared to meet Li Zexuan at Ganlu Hall.

This is the harem after all, and Li Zexuan is an adult and married normal man, of course he cannot be allowed to come here! If Li Zexuan was not married at the beginning of the year, Li Er might meet him in the harem, but it is absolutely impossible now.

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

However, the Queen of Longsun was also interested, she pleaded with Li Er.

"Haha! Since the maidservant Guanyin is interested, let's go together! But it's very cold outside, so you can add an extra dress for the maidservant Guanyin!"

Li Er laughed and agreed very readily.

"Thank your majesty for your concern, concubine saves yourself!"

The empress's heart warmed, and the maid put on a mink jacket for her, and the couple left now!
