When Lin Xi carried the strange-shaped stove into the study from outside, Li Hao almost glared out his eyes.

This old eunuch is not an ordinary person. Each stove weighs less than 50 kilograms. He can even keep his face and bend and take it in one hand.

Li Chengqian seemed not to notice this. After the stove was lifted in, he immediately took the opportunity to jump up and ran over to serve as a commander: "Come on, come on, put here, put another one on..."

Seeing Li Chengqian jumping around, Li Er was furious and said, "Damn it, come back and kneel down!"

Li Chengqian instantly turned into a frost-beating eggplant, and slipped back with a drooping eyebrows and kneeled down again.

Li Erze wandered to the coal stove and waved to Li Hao: "Li Dejian, come here for me."

"Hey, here we are!" Li Chengqian squeezed his eyes at Li Hao who couldn't steal the opportunity. Li Hao came to Li Er very hard.

"What is this?"

Li Hao smiled and said, "Your Majesty, this thing is called a coal stove. Put firewood, charcoal or charcoal and other combustible materials in and ignite it to keep warm. If you connect the tobacco pipe, you can also directly discharge harmful gases such as charcoal poison from the house."

"Well..." Li Er nodded, suddenly remembered something, frowned and said, "Wait, did you just talk about charcoal?"

Li Hao nodded: "Yes."

Li Er asked back: "Do you know that charcoal is charcoal poison?"

Li Hao said: "I know, but this thing can remove charcoal poison outside the house. Because of this, even if there is charcoal poison, it will not poison people in the house. His Royal Highness can use personality guarantees for this matter, and there is no problem."

Li Chengqian: “…”.

Li Er glared at Li Hao, turned to look at Li Chengqian, and half-believed and half-doubted: "Crown Prince, how is Li Dejian's words true?"

"Really, absolutely true!" Li Chengqian didn't care about asking for trouble for Li Hao and said anxiously: "Father, I have tried it myself, absolutely no problem."

In order to increase the credibility of Li Chengqian's words, Li Hao also helped: "Your Majesty, it's true. After the experiment was successful, your highness immediately ordered people to build a few such furnaces and bring them back, just to demonstrate it to you."

Li Er pondered for a moment: "Since that's the case, I'll give you a chance. If it doesn't work, be careful of your two."

"No! Thank you Father!" Li Chengqian escaped the disaster and jumped up again as fast as possible.

...

...

The installation of the coal stove is extremely simple. Just call a few craftsmen to open a hole in the window and then extend the smoke pipe out.

Li Chengqian had already prepared before returning from Xianyang, so he naturally had a quick and easy installation. He didn't have time to put on the coal stove.

After Li Hao ignited the carbohydrate he brought back with dry firewood, thick smoke suddenly came out of the smoke pipe that reached outside, and the temperature in the room began to rise gradually.

Li Er originally had no hope for the coal stove, but as the temperature in the room became higher and higher, the great Emperor began to unable to sit still.

He got up to the side of the stove, felt the hot temperature, sniffed, and asked in confusion: "Lin Xi, do you smell the smoke?"

Lin Xi had an incredible expression on her face, staring at the stove for a while, then she said in a tangled manner: "Your Majesty, there is no smell of smoke."

There is no smell of smoke, and it is burning charcoal.

What does this mean?

No one knows the meaning of it better than Li Er.

The people of the Tang Dynasty are blessed and will never have to worry about charcoal poison again. This is a great achievement. I can't say that I can also surprise those in the court who like to hear the news!

Li Er rarely showed a smile on his serious face, and he turned his eyes to Li Chengqian, and his voice was calm: "Prince, did you study this thing?"

Regarding this question, Li Chengqian had already passed by Li Hao on the way back and sighed: "Father, do you know Feng Xi? This man was a former Sui general and was a master of the furnace. Most of the credit was his. However, this man had broken legs in his early years due to an accident and now he has become an ordinary blacksmith in Xianyang."

Li Erdao: "So... did you go to Xianyang with Li Dejian to find someone?"

Li Chengqian felt guilty, looked at Li Hao, and said bravely: "This is not the case. Meeting Feng Xi is just a coincidence. Erchen originally planned to explore why people were infected with charcoal poison, but he never expected to meet him in Xianyang."

"Yes." Li Er nodded: "It seems that you are really lucky?"

While the old man was happy, Li Chengqian hurriedly said, "Father, do you think you are going to summon this person to Chang'an?"

"Let's stay in a few days. Let's solve your affairs in the next few days, and then call him to Chang'an and let me meet."

Li Hao was secretly happy when he heard this. The main reason why the old man was cautious was that he had too much credit and too sharp. This was why he was worried about being afraid of Li Er.

He suffered a loss and learned a lesson. With the old man's past, Li Hao naturally would not take on everything and make himself hateful.

The long-term solution is to give up the credit for making coal stoves in different ways and focus less on yourself.

...

...

It was already dark when Li Jing, who had been on duty for one day in the Ministry of War, arrived home.

The door of the mansion, which was hung with two irritating lanterns, was deserted. The housekeeper, who would always stand there waiting for the father-in-law to return, did not appear outside.

What did you give birth? Li Jing turned over and dismounted, threw the reins to the accompanying guards, and walked into the mansion.

The front yard, main hall, and side yard, the previous situation of servants running around was gone, but people vaguely heard from the back house.

Following the voices, Li Jing came to the back house. As soon as he entered, he immediately saw Li Hao standing proudly at the door.

When will this rebel come back?

Li Jing was slightly stunned.

When a servant in the yard saw Li Jing coming in, he immediately shouted: "The master is back."

"Master." A group of people in the yard greeted each other, and the housekeeper Lao Chen hurried over: "Master, you are back to your business."

"Well, what's going on?" Li Jing ignored his son who was walking towards him and turned to Old Chen and asked.

Lao Chen explained: "Master, the young master has returned from Xianyang and brought two magical stoves back. The servants were curious and came over to take a look."

"Then the stranger still has the face to come back." Li Jing snorted, not caring the so-called magical stove to heart.

Li Hao had already arrived in front of the old man at this time and gave a regular greeting: "Dad, I'm worried about you."

The old man could ignore him, but he didn't dare to ignore him.

Li Jing said with a nose that is not a nose, but a face that is not a face: "What are you going to do when you come back?"

Just when Li Hao didn't know how to answer, Hongfu walked out of the room: "Master, Dejian suffered a lot this time outside. As soon as he came back, why didn't you ask Qinghong to scold me?"

Li Jing: “…”
