Reminded by Li Chengqian, Li forgot to worry and finally found that he had forgotten to flatter his Majesty the emperor of the Tang Dynasty. It was a mistake.

Even Yu Shinan, who cares about his elders, has been ignored. He really shouldn\'t. And the dandies, how can I forget these dandies?

There are also Yang Zuan and Liu Xiao of Huxian county government, Qiu Kun, a fat man, and shopkeeper sun of Sun Ji bookstore. These are also friends.

Why do you patronize yourself to be cool? I didn\'t expect anyone else?

Li Qieyou blamed himself and hurriedly asked Niu Wu to ride to Huxian County, inform the shopkeeper at the mouth of the kiln and cook another batch.

However, he calculated and found that the quantity of porcelain to be fired was really large. Replacing a window requires more than 40 specially fired porcelain bottles and a door, which requires about 100 porcelain bottles.

And how many palaces in the palace?

Yu Shinan and Kong Yingda have few rooms in their mansion, not to mention Cheng Yaojin, Qin Qiong, Fang Xuanling and eldest sun Wuji.

Now he knows a lot of chaotang leaders. The demand for "ecological air conditioning" is really gone.

Thinking of this, Li forgot to worry and shook his head helplessly. He simply ordered Niu Wu to bring enough gold and go to the kiln mouth to inform the shopkeeper. Don\'t do anything these days. Just concentrate on helping him burn porcelain bottles. He wrapped up the kiln mouth of the shopkeeper for the time being.

As for the boards needed for ecological air conditioning, we can\'t rely on carpenter Liu. The old man and his three sons are tired to death. I\'m afraid they can\'t do much.

Li forgets to worry about it, and simply asks Li Heng to accompany Niu Wu to the Huxian county government to find Yang Zuo for help. Let Yang Zuan find a craftsman in Huxian county to help him process the wooden base.

After arranging these chores, Li forgot to worry about waiting for the kiln mouth to burn the porcelain bottles, and then transport these ecological air conditioners to Chang\'an city to give gifts.

But before he went to give gifts, a group of uninvited guests came to the door first.

On the second day of their return to Chang\'an City, Li Chengqian and Li Tai led a group of "bandits" to Dingzhou village in the early morning.

Li forgets worry and is startled by the murderous Li Er and Cheng Yaojin. What are you doing? Want to come and fight with yourself?

It\'s early in the morning. It\'s not a rest bath today. Don\'t Li Er and these big men often go to court?

"Ziyou, why don\'t you want to honor your uncle and your aunt when you make a good thing? It\'s time to fight! If Chengqian and Qingque didn\'t come back and tell me, I would still be hidden from the drum!"

Li Er didn\'t wait for Li forgetful to speak. He scolded first. He was so angry that Li forgetful\'s teeth itched. Those two damn little traitors, little bastards! Eat well, drink well and enjoy enough at home. Unexpectedly, I sold myself back!

Li forgets worry and secretly makes up his mind that when Li Chengqian and Li Tai come next time, they must have a taste of his teacher!

Hum! It\'s a good idea to copy the humble room inscription a hundred times!

He naturally knew what Li Er meant, which was the ecological air conditioner he made.

Yesterday, he specially explained the principle of ecological air conditioning to Li Chengqian and Li Tai, which is a scientific enlightenment course.

Li Qieyou also shamelessly told the second primary school that the ecological air conditioner was called "air conditioning window", which he painstakingly studied. Therefore, the white eyes of the beautiful boss are turning to the sky. I really can\'t see his shameless appearance.

But I didn\'t expect these two little bastards to talk so fast. As soon as they returned to the palace, they went to find Li Er to offer treasure. As a result, Li Er, who was suffering from the heat these days, stopped even Chang Chao and directly led a group of leaders of the hall of the court to kill Dingzhou village.

Li forgot to worry and quickly explained that it would not be a good thing if he was hated by the imperialist leader of the Tang Dynasty.

"Uncle, where is this? My nephew just experimented first. After the effect is good, he is ready to give it to my uncle."

As soon as he finished, Cheng Yaojin was dissatisfied again. A fluffy black face came up and saliva was about to spray on his face.

"Boy, where\'s my? You have the heart to let your uncle Cheng suffer from the heat. Is it itchy? If you don\'t hand over the air-conditioning window today, I won\'t go!"

"Uncle Cheng, how can I forget you? Hey, yes, yes, I have prepared it for your family. However, the air-conditioning window is still burning, but it can\'t be finished in a moment. I must deliver it to Uncle Cheng\'s house in person in two or three days at most."

As soon as Li forgot to worry about this, he felt a stabbing pain in his back. Turning around, he saw the murderous eyes of big men such as Fang Xuanling, Du Ruhui and changsun Wuji.

He didn\'t understand what these big men meant, so he quickly bowed with his hands and said, "gentlemen, I have prepared for the Duke\'s residence. As long as the craftsman makes it, I\'ll send it to the Duke\'s residence."

Li forget worry\'s interesting appearance made these big men nod their heads to their satisfaction. They didn\'t need Li forget worry to greet them. They consciously poured into the Li family\'s old house.

As soon as they entered the gate, they noticed the water curtain flowing down from the roof. The water in the yard was obviously cooler than that outside the yard. The pattering sound of water adds a bit of elegance to the house.

Li Er naturally saw the bamboo tube on the roof and said with envy, "Ziyou, your residence has found a good place. It\'s not easy to have the spring cooling behind the green mountain."

A group of big men are also quite envious, but they have nothing to do.

After all, their residences are in Chang\'an city. They can\'t transport well water to the roof by manpower, can they?

Li Er and Fang Xuanling would not do such a stupid thing to relieve the summer heat, but some people really did it.

It is recorded in the Wen Jian Ji of the Feng family that Wang Ying, the powerful minister of Xuanzong of the Tang Dynasty, built a pavilion that would rain in the house of Taiping square, West Street of Chang\'an city. On the eaves of the pavilion, water flows everywhere.

Living in the pavilion in midsummer is as cool as late autumn, while the outside of the pavilion is still hot. The separation of one Pavilion makes people feel the difference between ice and fire.

In Chang\'an City, there is no other way to let the pavilion flow like rain, except to transport the well water up and pour it.

In fact, in the Qinling Mountains, there are also Royal Summer Palace and Cuiwei palace.

Cuiwei palace is not far from Dingzhou village, just in Huangyu of Qinling Mountains, also known as Huangyu. It\'s seventy miles from Chang\'an City and forty miles from Dingzhou village. It\'s only half an hour by horse.

These days, because of her pregnancy, empress Chang sun really can\'t stand the heat in Chang\'an City and is ready to go to Cuiwei palace for summer vacation.

Li Er was reluctant to give up his daughter-in-law. I heard that after Li forgetful created the summer heat reducing artifact, he came to Dingzhou village early in the morning to see if the air-conditioning window was really effective.

After all, empress Chang sun has been pregnant for eight months. Seeing that she is about to give birth, Li Er doesn\'t want her daughter-in-law. At this time, she goes to the palace for summer vacation.
