Datang: Integrate three times the combat power of Lv Bu at the beginning

A total of [-] bags of cement were piled up in the warehouse next to Luban Pavilion.

Looking at the cement, Li Chengqian couldn't help but beam with joy.

You can set up a kang, and finally you don't have to suffer from the cold at night.

After the cement was finished, Li Chengqian rewarded the laborers and dismissed them.

The next step is the work of the bricklayer, and no manual labor is needed.

Li Chengqian handed a sketch of the kang he drew to Sun Liuchuan: "How about it, do you understand the drawing?"

"This... is this a bed?" Sun Liuchuan showed doubts: "But this blueprint, I can understand it."

Li Chengqian explained: "This is called a kang, which has an excellent effect of keeping out the cold in winter."

Hearing this, Sun Liuchuan was still at a loss: "The heated kang? To keep out the cold? I'd better build the heated kang first for a humble job."

Due to the principle of not moving the kang, he didn't ask.

Sun Liuchuan led the bricklayer to make a hole in the wall of Li Chengqian's bedroom. The outside was the stove and the inside was the bedroom.

A stove is built inside the stove room, with a stove door, ash cleaning port and air inlet.

The stove cover is very large and can be filled with a lot of firewood.

Sticking to the wall is the kang, which is built with cement and bricks.

The middle of the heated kang is empty, and the hot current of the heat surges inside to provide heat for the heated kang.

On the far right is a chimney leading to the roof.

The people led by Sun Liuchuan were very agile.

In less than a day, the kang was built.

Then, it is drying and baking.

When a fire is lit in the stove, the hot current will bake the kang until it is hot to the touch.

Sun Liuchuan and the others were speechless in surprise.

Although the kang was made by them, they were amazed by the uncanny creativity.

"His... Your Highness..." Sun Liuchuan looked at Li Chengqian tremblingly: "This thing? We built it?"

"En." Li Chengqian nodded lightly: "Aren't you responsible for everything from cement production to kang construction?"

Sun Liuchuan put his hands on the hot kang, and said quietly: "But I can't believe this is true."

He has unlimited expectations in his heart.

In the cold winter, what kind of fairy day would it be to sleep on this warm kang head all night.

"Hehe..." Li Chengqian smiled lightly: "Isn't there still cement in the warehouse of Luban Pavilion? You can build a heated kang in Luban Pavilion. When the cement factory is built, this palace will not only let all the people of Tang Dynasty sleep on the heated kang , and even the houses are all built with cement.”

Hearing this, Sun Liuchuan widened his eyes, clapped his hands and exclaimed: "That's right! If you build a house with cement, the ability to resist the wind and cold will be ridiculously strong. Your Highness, you are really a god, such a magical thing. You can develop it."

"Okay, okay." Li Chengqian waved his hand: "You all step back, I need to rest well. By the way, the cement production cannot be stopped. I guess you are busy these few days."

"It's His Royal Highness the Crown Prince." Sun Liuchuan responded, "The humble post will be resigned."

After the words fell, he hurriedly led the crowd towards Luban Pavilion.

It is planned to build a big heated kang in Luban Pavilion.

"His Royal Highness, what... what is this?" Ling'er walked into the bedroom, looked at Li Chengqian who was lying on the kang, and asked doubtfully.

Li Chengqian patted the kang head and said: "This is a heated kang. Sleeping on it in winter is absolutely as comfortable as a god."

"Fire kang?" Ling'er sat up in doubt.

Just sitting on it for a while, I suddenly jumped up ∑ (O_O.): "Ouch! It's on fire."

"Hehe..." Li Chengqian shook his head and laughed, "Where did the fire come from? It's just the heat on the kang."

"How could this happen?" Ling'er said, carefully stretching out her hand to the kang, and said joyfully, "Yo! Your Highness, this kang is really warm to the touch."

Li Chengqian said to her: "Wait tomorrow, I will ask Sun Liuchuan to build a kang for the wing you live in."

Hearing this, Linger had a smile on his face (????): "Your Highness, don't you have this ready-made? Linger is here."

Li Chengqian (╬￣dish￣) "..."

……

Li Chengqian hadn't lived in this kang for a few days, and the news spread all over the palace.

"Have you heard? There is a magical couch in the prince's courtyard, which can generate heat by itself. It is very comfortable to sleep on in the cold winter."

"Hey, I've heard Linger say it a long time ago. She said that His Royal Highness wants to build a wing for them. I'm really envious of me."

"When will I be able to transfer to the Prince's Mansion? Last time Ling'er was in danger when she returned home, His Royal Highness the Crown Prince rushed to Feng Yicheng to rescue Ling'er, and everyone else envied her."

"You? You don't even look at your appearance, did you use to be the door god for the Prince's Court?"

In the palace, the maids gathered together and whispered.

Li Shimin, who was passing by, frowned when he heard what they said: "Chen Lin, there have been rumors in the palace these days that there is a couch that can get hot by itself in the Prince's Courtyard, have you heard about it?"

Chen Lin possessed her body and said: "I heard about it, that thing seems to be... called a heated kang, and it is said to be extremely magical, and Han Ye sleeps on it, without feeling the slightest chill."

Li Shimin stopped and raised his eyebrows: "Is this thing so magical?"

"It's hard to say..." Chen Lin shook her head and said, "I've only heard about the humble job."

Li Shimin paced back and forth, fidgeting (?￣︿￣): "This child is really outrageous, there is such a fetish who doesn't want to think about me, but only for his own enjoyment, what is filial piety?

Let's go, move to the Prince's Courtyard, I want to see what this heated kang is. "

Chen Lin hurriedly said: "Your Majesty, those princes are still waiting for you in the imperial study."

Li Shimin pondered: "Call them together."

Chapter 305 I'm Waiting For Your Words

palace...

Li Shimin led all the princes to the prince's mansion aggressively.

"Your Majesty, do you think the Prince's Mansion is on fire?" Cheng Yaojin pointed to the thick smoke coming out of the Prince's Court and asked in surprise.

Everyone looked around after hearing the reputation, but thick smoke was billowing from the direction of the Prince's Mansion.

Chen Lin smiled and said, "Don't be surprised, Duke Lu. This should be the chimney coming out of the kang developed by His Royal Highness."

Li Shimin showed displeasure on his face: "Hmph, he spends all day doing these infamous things in the palace. If he doesn't demolish my palace, he won't feel at ease."

After listening to Li Shimin's words, the several princes stopped talking.

Your Majesty is not in a good mood, they don't want to touch this bad luck.

lean less...

"Your Majesty is here." The eunuch Chen Lin's voice sounded in the Prince's Mansion.

Just as Li Chengqian was about to get up to pick him up, Li Shimin rushed in with someone impatiently.

"Father? Why are you here?" Li Chengqian was sitting on the kang, eating candied fruit, sipping tea, and thinking about life.

"Hmph..." Li Shimin said displeasedly: "I'll take a look, what is the filial emperor doing?"

Looking at the huge couch, Cheng Yaojin was curious: "Your Highness, your couch is really..."

"Oh..." The moment his hand touched the kang, he immediately withdrew it.

Li Shimin turned his head and glared at him with a gloomy face.

Cheng Yaojin scratched his head in embarrassment: "Your Majesty... Your Majesty, I... this kang is hot, hehe..."

Li Shimin ignored him, and scanned the room for a week: "Your bedroom is much warmer than my bedroom."

After the words fell, everyone suddenly felt that the temperature in this room was indeed much higher than that of ordinary rooms.

Here, I don't even feel the cold.

Li Chengqian invited: "Father, the weather is very cold, please sit down and keep warm."

"Hmph..." Li Shimin said with a gloomy face, "I haven't seen anything, you can still..."

As he spoke, he sat up and felt a rush of heat rising from his buttocks.

Sweeping away to the whole body, it is warm and very comfortable.

"Oh..." Li Shimin's face was rosy, and he looked very enjoying, and he cried out unconsciously.

Li Chengqian said softly: "Father, how is it? The temperature of the kang is not bad."

"Okay, very good..." Li Shimin closed his eyes, as if he had never seen the world: "Emperor, why don't you tear down my bedroom."

Li Chengqian: "..."

Cheng Yaojin: "..."

Changsun Wuji: "..."

……

Didn't you just say that Li Chengqian wouldn't feel at ease if he didn't demolish your palace.

Why did he take the initiative to ask for it again.

It's really the emperor's mind. Don't guess, it's useless to guess.

Cheng Yaojin had flattery on his face: "Your Majesty, we also want to feel this heated kang..."

"Huh?" Li Shimin opened his eyes: "Everyone sit down."

Everyone was overjoyed and couldn't wait to sit on the kang.

Fortunately, the kang built by Li Chengqian was big enough, otherwise it really wouldn't be able to seat so many people.

"Comfortable, extremely comfortable, I have never seen such a magical bed, it is so warm."

"His Royal Highness is really ingenious, such a miraculous thing can be created."

"If the people of my Tang Dynasty could sleep on the kang in every household, the people would no longer have to suffer from hunger and cold."

Everyone sat on the kang, full of emotion.

Wei Zheng asked: "His Royal Highness, what is your kang built with, and why is it so strong?"

Hearing this, everyone showed curiosity.

This heated kang was covered with a layer of cement.

They had never seen concrete, so they couldn't tell from the outside.

Li Chengqian said in a low voice: "It's made of Tang strip bricks and cement."

Wei Zheng frowned, and touched the outer layer of the kang with his hand: "What is cement? Why has the old minister never heard of it."

Li Chengqian responded: "Cement is the latest building material developed by the palace, which did not exist before. Cement has high compressive strength, strong aging resistance, good light weight, good sound insulation effect, and good high temperature resistance. The buildings that have been built are extremely solid.”

Everyone was dumbfounded when they heard the words.

There is such a magical thing in this world?

Or was it developed by the prince?

Is he the Creator reincarnated?

The triple question of death lingered in their hearts.

"Huh..." Li Shimin on the kang showed a disdainful expression: "This thing of yours is harder than my city wall?"

Li Shimin believed in saying that the kang head was warm, but Li Chengqian said the cement was like a heavenly thing.

Li Shimin couldn't believe it.

He thought to himself, you are good at fighting, governing the country, managing the people, medical skills, farming, cooking, and are proficient in everything.

But if you want to say that you are a bricklayer, I will not believe it to death.

Li Chengqian had no intention of arguing with Li Shimin, and said with a light smile, "Father doesn't believe it, that's all."

Li Shimin rolled his eyes, this kid's attitude is obviously a sign of guilty conscience.
