Previously, when Li Tai and Li Chengqian entered the house, Li Zexuan and his family were sitting around a coal stove and eating hotpot. Although the two brothers felt that the house was very warm, they only thought that it was because there was a stove in the house.
Recently, coal stoves and honeycomb briquettes had become very popular. They had seen it before, so they weren't very surprised!
However, after the coal stove was removed, the temperature in the house didn't drop at all. It was still as warm as before. This made Li Tai feel strange!
"That's right! Xiaoxuan! Is there a heater somewhere in your house? Why is it so warm? "
After Li Tai's reminder, Li Chengqian also reacted. He sat up straight and asked.
"Hehe! There isn't a heater in this house. Qingque, you've taken 'Chemistry' class before. You should know that a heater can poison people, right? "
Li Zexuan shook his head and laughed.
Li Tai rubbed his chin and thought for a moment. He nodded and said, "There is such a saying! However, if there isn't a heater in this house, why is it so warm? Yamachō, don't keep us in suspense! "
Li Chengqian nodded in agreement. He also looked at Li Zexuan curiously.
Li Zexuan pointed at the row of heaters behind Li Tai and said, "There! Go and touch that piece of metal and you'll know why! "
When Li Tai heard this, he couldn't help but retract his hand. You want me to touch a 'cold' piece of metal in the middle of winter? Isn't that asking for my life? I'm very afraid of the cold!
Li Chengqian saw Li Zexuan's solemn vow and felt that Li Zexuan wouldn't deliberately trick him. He stood up and took two steps forward. Then, he reached out to the metal heaters. The expected cold didn't come. Instead, it was a very comfortable warmth. This warmth was even a little hot!
"This … What's going on? Not only is this lump of metal not cold, but it's also hot! This is really strange! "
Even though Li Chengqian was mentally prepared, he was still very surprised at this moment. This clearly went against common sense!
"Eh? Let me try! "
Hearing this, Li Tai immediately perked up. The little fatty walked to Li Chengqian's side and placed his white and fleshy palm against the radiator. Sure enough, what he felt was warmth and not coldness.
His eyes lit up and he said excitedly, "Yamachō, I understand! It's because of this iron lump that your room is as warm as spring, right? "
Lan-er rolled her eyes and said disdainfully, "Tsk! What a lump of iron! This thing is called a radiator. There's a heater in it, so of course the house will be warm ~? "
"Radiator ~?"
Li Tai was stunned. He didn't have time to fight back against Lan 'er's disdain. He turned to Li Zexuan and said, "Yamachō, do you have any extra radiators? I want to install this in the Imperial Residence as well! "
Li Chengqian also nodded vigorously and pleaded, "Yes! Little Xuan! This radiator is really useful. Do you have any more? I'll take it back and install it in the palace as well! During this winter, father, mother, and Changle all suffer. I was planning to raise money for father and mother to repair the palace! Now it seems that this radiator is enough! "
Li Zexuan originally made this radiator for his family to enjoy. He gave it to Li Gang out of respect for the old man's scholarly character. He also planned to prepare another set for the Qin Family. He didn't expect that before he had time to prepare, the two brothers, Li Tai and Li Chengqian, came to ask for it!
However, he couldn't not give it to them because he wasn't worried about whether Li Chengqian would suffer or not. He, who had transmigrated from the modern world, knew that Li Chengqian would sit on the throne for many, many years. However, it was different for Zhangsun and Changle! These two extremely virtuous women also contributed a lot to the prosperity of the Tang Dynasty. According to history, they couldn't escape the fate of death!
According to historical records, one of them died in the tenth year of Zhenguan at the age of thirty-six. The other died in the seventeenth year of Zhenguan at the age of twenty-three!
Li Zexuan admired Empress Zhangsun and Princess Changle very much. He didn't want these two women to die early from illness!
Empress Zhangsun's influence on Li Chengqian didn't need to be mentioned. Since ancient times, when a country was about to prosper, there would be a wise ruler and a virtuous empress. Empress Zhangsun protected righteous subjects and lived up to Guan Ju's beauty!
As for Li Lizhi, as the pearl in the emperor's palm, she didn't take advantage of her parents' doting to become arrogant. After marriage, she was filial and respectful. When the court officials couldn't persuade her father to cede land to meritorious subjects, she stood out to help at the crucial moment and put an end to the hidden danger of the Tang Dynasty's provinces being divided!
In Li Zexuan's view, these two women died because of their illness. They were the two biggest regrets of Zhenguan's golden age!
From the modern era to the Tang Dynasty, Li Zexuan saw the two women he admired. One treated him like an elder, while the other was like his own little sister. He didn't want these two women to die from the bottom of his heart!
Previously, he had asked Han Yuxi to teach Changle Tai Chi. He didn't know if this little girl persevered every day. In fact, even if she persevered every day, Li Zexuan didn't have the confidence to cure Changle's illness through Tai Chi.
Illness was similar to asthma. It was a stubborn disease that couldn't be cured in modern society! All Li Zexuan could do was try his best to reduce the frequency of Changle and Zhangsun's illness.
Winter was the peak season for asthma. The cold air irritated the respiratory tract mucosa and could easily cause asthma. Therefore, the imperial palace also needed heating!
"Chengqian, this radiator needs to be customized with the heating pipe, and the heating pipe needs to be planned according to the specific size of the building. You can install heating in the palace, but you have to provide Faubert with some size data. Otherwise, if the heating is not suitable, it will easily cause problems!"
Li Zexuan said.
This was considered to be an agreement to Li Chengqian and Li Tai's request for heating. However, unlike modern advanced production processes and technology, the heating pipe made by the workshop was custom-made and formed in one piece. With the workshop's current technology, it was still a little troublesome to make the modern air valve that connected the pipes. Therefore, if Li Chengqian and Li Tai wanted to install heating, it had to be custom-made!
This was also one of the reasons why Li Zexuan didn't plan to use heating to make money. This was because the heating technology he made was relatively backward and not suitable for mass production. It wouldn't be too late to promote the heating business when the technology matured in the future!
Li Chengqian was stunned. He said awkwardly, "If that's the case, I'll go back to the palace and ask Father!"
The architectural drawings of the imperial palace were confidential. How could they be easily leaked to outsiders?
Li Tai laughed and said, "Haha! Then I'll go talk to Faubert in the afternoon and ask him to build a heating for me first! "
This guy didn't have so many scruples. As long as he could enjoy it, it was fine!
