Li Chengqian calmly stepped forward and saluted, "See Father!"

When Li Shimin saw Li Chengqian, he smiled and said, "Hurry up and sit next to me!"

From Li Shimin's voice, Li Chengqian could tell that he was a little weak now. Perhaps this was his so-called qi disease that affected him.

At this time, he had a natural mentality of closeness and dependence towards Li Chengqian.

Li Chengqian stood up straight and smiled, "Congratulations to Father, congratulations to Father!"

Li Shimin was stunned when he heard this, and smiled faintly, "Oh, where is my joy?"

Li Chengqian walked forward and smiled and said, "Isn't it a happy event for my son to get a divine object to relieve the pain of the father's heat?"

Li Shimin laughed and said, "What good thing is it for me to see?" Li Shimin was very pleased with Li Chengqian's filial piety.

As soon as Li Chengqian approached Li Shimin, he found that Li Shimin's face was already swollen, and it was dark now that he obviously didn't sleep well last night.

Sitting next to Li Shimin, you could clearly hear his short breath, and it was obvious that he was suffering from his physical discomfort at this time.

Because he turned around and said to the old ghost who was rushing to follow him, "Let them carry it in?"

The old ghost hurriedly lowered his head and walked out of the hall with small steps, and soon brought a few people in with them carrying things.

Li Shimin and the ministers looked over curiously, and saw a few guards carrying a large jar, and then someone carried an empty box without any bottom, someone holding a strange three-leaf fan, and finally a few people carrying buckets.

Seeing that everything was carried in, Li Chengqian stood up and walked to the middle of the hall, directed the guards to pour the water into the tank, then fixed the fan blades in the box, and swayed the fan inside the handle from outside and quickly turned it.

After the box was installed, Li Chengqian stretched out his head and saw that the water in the water tank had begun to freeze. He ordered someone to hold the box on the water tank and ordered someone to rotate the handle behind it.

A cool breeze that was close to the person immediately felt blew out of the box. After a closer look, it turned out that the box was facing the hall, and only half of the lower part was sealed with wooden boards, leaving more than two feet high on it, and the wind blew out from it.

Li Shimin also slowly walked off the throne and stood beside him, looking at this strange thing curiously. Seeing the cool breeze blowing out, he felt a little comfortable, closed his eyes and breathed a long and comfortable breath.

When Yang Shidao saw this, he hurriedly said, "Your Highness the Crown Prince is really kind and filial, and knows that Your Majesty is irritable and unbearable to the heat, so he specially made this thing to relieve Your Majesty's bitter summer."

Li Shimin was very helpful when he heard this, opened his eyes, looked at the wooden box in front of him and Li Chengqian and said with a smile, "Chengqian is intent, I will bring this box when I go to Jiucheng Palace."

Li Chengqian looked at Li Shimin and said with a smile, "If you have this air conditioner box, your father doesn't have to go to Jiucheng Palace."

Li Shimin looked at the air conditioner box that Li Chengqian mentioned and then looked at Li Chengqian. Finally, he smiled bitterly and said, "Although this thing can blow out the cool breeze, it is just a drop in the heat and it will not help..."

Li Chengqian smiled slightly when he heard this and said, "Father, look!" As he said, he winked at the guards standing next to the air-conditioning box, and ordered them to carry the wooden box.

Following Li Chengqian's voice, Li Shimin looked into the tank and saw that there was a tight tank of ice in the tank.

Li Shimin couldn't help but take a breath and looked at Li Chengqian in shock and said, "Chengqian, what kind of magic are you playing with?"

Li Chengqian smiled and said, "This is not a magic. My son just put some saltpeter in the water. The water freezes when it meets saltpeter. The cold air is blown out with the wind leaves in the wooden box, and then the entire hall becomes cooler."

"Oh!" Li Shimin nodded when he heard this, then looked at Li Chengqian and asked, "Why does water freeze when it encounters saltpeter?"

...

Li Chengqian's mind got off the blocker and wanted to say loudly how did I know?

However, he glanced at Li Shimin and several curious ministers and had to fool him, "The heaven and earth are mutually reborn and restrained. Water meets saltpeter freezing, which is the same reason..."

Li Shimin reluctantly frowned slightly when he heard his explanation and asked, "What Chengqian means is that I don't have to go to Jiucheng Palace with these air conditioners?"

Li Chengqian could hear Li Shimin's question full of suspicion, and said calmly, "The whole of Guanzhong has been very hot these days, and the father has not been asleep for several days. If he hurried to Jiucheng Palace at this time, he might not be able to walk on the road."

Although this was said implicitly, everyone in the palace understood it. Li Chengqian was worried that Li Shimin would be sick on the road, so he couldn't help but nod and thought to himself that His Royal Highness the Crown Prince is really filial.

Li Shimin was also in a difficult mood. He knew that the road was difficult, but the Tai Chi Palace was too stuffy and the imperial palace stored a lot of ice. However, the ice naturally melted and absorbed heat, and moisture also dissipated, causing excessive moisture in the house to be too severe for people with qi diseases. Therefore, he had to go to Jiucheng Palace to calm down every summer.

While Li Shimin was hesitating, he heard Li Chengqian calmly answering, "Anyway, my father will not leave the palace today. My son has asked someone to prepare dozens of wooden boxes to find some water tanks to put saltpeter in this hall, so that they can make ice with water. My father will try it out if it can cool down a little?"

Seeing that Li Chengqian was sincere, Li Shimin couldn't bear to smear his intentions on such trivial matters, and nodded silently to agree with Li Chengqian's proposal.

Li Chengqian said to the old ghost, "I ordered people to close the doors and windows in the hall, and then place the water tanks around the hall, so that the cold wind can blow in."

The old ghost lowered his head and responded with a loud voice, turning around and taking small steps out.

Li Chengqian turned around and helped Li Shimin back to the throne. After Li Shimin sat down on the throne, he looked at Li Chengqian's words to the eunuch beside him, "Tell me my order, the eunuch province will stop all preparations to leave the palace first."

The reason why Li Shimin didn't leave the palace today was because he issued an order for the provincial eunuch to prepare for a few days before he could leave the palace. Logically speaking, he should have enjoyed Li Chengqian's artificial air conditioner first, and then asked the prepared people to stop.

But Li Shimin saw that Li Chengqian was indeed filial, how could he show that he did not trust Li Chengqian in these trivial matters?

And even if Li Chengqian's experiment failed in the end, Li Chengqian and the ministers of the East Palace would naturally make up for their merits and send him to Jiuzheng Palace as quickly as possible.

"Father, don't worry, this air conditioner box will definitely reduce the temperature in the hall!"

When Li Chengqian saw that Li Shimin really believed in him, he was still a little moved. After all, the purpose of his presentation of artificial air conditioners this time was impure.

Li Shimin looked back at Li Chengqian and nodded, and then began to discuss state affairs with the ministers. Many things Li Chengqian had conveyed his views through several Grand Secretary of the Chongjiao Hall, and he did not speak anymore and sat next to him and listened quietly.

The old ghost and his people quietly arranged air conditioners one by one and began to cool down the hall. The sun gradually rose, but the boring high temperature did not fall into the Liangyi Hall.

In Liangyi Hall, as more and more air-conditioning boxes were air conditioning, the temperature was getting lower and lower. Li Shimin felt the long-lost coolness and his spirits were much better than in the morning.

"I heard from Your Majesty Xue Yantuo's envoy Tuli Settlement in two days to enter Chang'an. The Ministry of Rites intends to summon him in Liangyi Hall." Li Daozong, the Minister of Rites, Qidao.

The ministers in the palace heard that Juyiyijing was the nephew of Xue Yantuo's Zhenzhu Khan. This time he went to the Tang Dynasty to marry the princess of the Tang Dynasty. He should be summoned at the Taiji Hall, so why did the Ministry of Rites arrange it in Liangyi Hall?

Li Shimin looked at Li Daozong waiting for him incredible words, but after a while, he heard Li Daozong say, "All the generals in the court oppose this marriage, so the Ministry of Rites think it should not be too ostentatious."

"Hmph!" Li Shimin snorted angrily to express his dissatisfaction.

Seeing this, Li Chengqian quickly stood up and walked off the throne, and politely said to Shimin, "This is the fault of a son. You should not have done any random poems to disturb the state affairs. Please punish the father."

Li Shimin saw that Li Chengqian didn't say anything when he heard this, and then looked at Li Daozong again, and his attitude was very clear that his son could not take the blame.

Li Daozong did not expect that Li Chengqian suddenly turned against him and was unable to move forward and retreat. When he was about to speak, he saw Hou Junji stand up and said, "Your Majesty Xue Yantuo is just a small family. Although the Tang Dynasty is in harmony with him, it should not be too solemn, which will make him feel arrogant and arrogant."

Li Shimin looked at Hou Junji for a while and said, "I think about it again!"

Seeing that Li Shimin was a little moved, Li Chengqian hurriedly bowed and said, "The father's marriage is different from the past, and should be grandly welcomed. It is best for the father to climb to Chengtian Gate and declare this to all people in the world."

After hearing this, Li Shimin had not spoken yet, Hou Junji spoke first and bowed to Li Chengqian, "I would like to ask the prince, how is the difference between this marriage this time and the past?"

When Li Chengqian heard this, he looked at him and said indifferently, "In the past, whether in the previous dynasty or the Tang Dynasty, they were often when China was unable to conquer the foreign barbarians, so when they were married, they often accompanied a large amount of wealth to bribe foreign troops.

This time, the marriage between the Tang Dynasty and Xue Yantuo was when Xue Yantuo could be destroyed by the Tang Dynasty. It was Xue Yantuo Khan admired our Chinese literary talent and willing to take coins and marry a wife.

This relationship naturally requires the imperial edict to the subjects and states of the world to demonstrate the mind of the Emperor of Tang.”

"Okay! Let's handle it as Chengqian's proposal!" Li Shimin seemed to be ten years younger after hearing Li Chengqian's words.

Li Shimin has always praised himself for his martial arts. After reading Li Chengqian's poems, it was not that he had no feelings. It was just that state affairs were the priority. At this time, Li Chengqian found such a good reason for marriage for him. How could he be unhappy?
