"But there were hundreds of students in that bookstore, which alarmed the elders in the family. The five surnames and seven sects watched the world for a hundred years. The ups and downs of many dynasties have long been used to taking three steps in one step! That bookstore is open to poor students. If there were more such books in the Tang Dynasty, children would not need money to read and recognize words. The poor students had a way out and cooperated with Li Shimin's imperial examination, that would be the biggest blow to our five surnames."

The Li disciple has never expressed his opinion, and no one else can see what the Li child is thinking. His expression is very leisurely, but he turns a deaf ear to the words of the people around him.

The Li family of Zhaojun is the largest of the five surnames and seven sects. After Li Mu, a famous general of the Warring States Period, the Li family of Zhaojun has a deep foundation and confidence. The branches of their family are also the widest. Putting aside the Li family, which is the emperor, the Li family of Zhaojun has a high status among the five surnames, and the Li family is the most powerful. The Li family has left Zhaojun and looked at each other in Longxi! But when the various aristocratic families were in danger, the Li family fell silent.

The Wang family members stood up and bowed, "My brothers, I have to say goodbye in advance at home."

Among the five surnames, the Wang family belongs to the weakest lineage, but the Wang family is also the most stable lineage.

Several children of aristocratic families by the river bank each had their own ideas.

Chang'an

Li Chengqian was playing chess with his princess in the East Palace. He felt much less bored these days. It was rare for the princess to see her in such a good mood, and her mood also improved. Last night, the prince said he wanted a child. This sentence is happier for the princess than anything else.

Li Chengqian now knows that as long as he takes the struggle in the palace indifferently, he will understand a lot. Perhaps he wants to get too much, and he will suddenly become enlightened after walking out of this cloud. "The cost of the palace has been tight recently. If we can be frugal in the East Palace, we should be more frugal."

"I understand." The Crown Princess said.

"Your Highness, Prince." A palace maid came to report, "Your Majesty summoned him."

"I know." Halfway through the chess, Li Chengqian stood up and changed into his robe. Only now did he realize that Gu Qing was just a guy with no ambitions, a person who just wanted to follow him. This man never regarded himself as an enemy.

The Crown Princess helped Li Chengqian pack up his clothes and makeup, "Your Highness, I will prepare dinner for you."

"Yes." Li Chengqian nodded, packed up and left the East Palace.

The Crown Princess looked at him with pride. Since she met Gu Qing, the Crown Prince has been neglected and has not even been satisfied with going out normally.

Li Chengqian came to Yanqing Hall and saw Li Tai and Fang Xuanling. Changsun Wuji was chatting, and Li Tai was there too.

Li Er said with doubts, "Is this idea really what Gu Qing came up with?"

"Yes, my father." Li Tai replied.

It was Gu Qing and Li Tai, and Li Chengqian could hear a rough idea.

Li Er looked at the silent Li Chengqian and said, "What do the prince think?"

"My son thought he could try it and get closer from Tuyuhun." Li Chengqian continued, "Although this idea is good, it still needs to be carefully crafted."

Listening to the prince's words, Li Tai was puzzled that if the two brothers fought each other, Li Chengqian would find out the problem and refute him. But now he felt that he was going downhill, and what was wrong with the prince? As he thought about it, he thought of Gu Qing's bad face. What would he say if Gu Qing was here? A group of big men were so openly about other people's money. Is it shameless! More shameless than me, Gu Qing would probably say that.

Li Tai fought a cold war.

Li Er looked at his prince and looked puzzled. Why didn't Li Chengqian refute Li Tai? This was a very strange signal, sitting expressionless.

Fang Xuanling also said, "Your Majesty, we can start with Tuyuhun and try it step by step."

Li Er nodded, still wondering why his prince didn't argue with his second son, which was incredible...

Gu Qing was looking for something that could replace insulation materials in his village. Wood is not good, can it be made with cotton? It seems that it is not durable, but it will be useless when it encounters moisture.

The first is vacuum insulation. This condition is not difficult. After thinking about it, the best material is your own glass, but glass is sky-high. I just sold so much and made a lot of glass to make hot water bottles? Will this ruin the Tang Dynasty's glass market?

While walking, Gu Qing saw a father and son roasting a hare rabbit. The father said to the child, "Don't roast this rabbit meat too cooked. The too cooked meat tastes too ripe and tastes bad."

The child nodded too.

The father and son are hunters in the village. Gu Qing knew them too well? Too familiar? Half-baked? Thinking of this, I suddenly realized my thoughts and searched for them without searching! It turned out that there was such an operation! It doesn’t matter whether the insulation material is glazed or not, as long as it has the components of glazed.

The glass is half-baked, so that others can’t tell that it is glass, but this is glass! As long as it has the chemical composition and heat insulation function of glass, it’s good.

It turned out that he had wrapped himself in the horns. Gu Qing smiled and returned home and started to make a thermos bottle. In the future, if you want to drink hot tea, you don’t have to wait to boil water.

When I returned to my doorstep, I found that there was a guest at my house. A carriage was parked at the doorstep. There was a cool boy sitting in the carriage, biting the grass roots in his mouth. His virtue was similar to that of Yang Sheng.

"Who are you?" Gu Qing asked.

"Who are you?" the other party asked in a higher tone.

"I'm still a little arrogant!" Gu Qing frowned and asked again, "Do you know who I am?"

The spring breeze blew, and the young man looked at Gu Qing, "I care who you are!"

Gu Qing was not happy to be challenged at the door of his house, "Do you know whose home this is?"

"It's not your home." The boy still looked cool.

"This is really my home!" Gu Qing replied.

"Zhang Jie, don't be rude!" Wu Shun took Wu Mei out of the house and said to Gu Qing again, "I'll come to see my sister, but I just didn't come to report it in advance. "

"It's not important, it's not important." Gu Qing waved his hands repeatedly.

"Haha!" Zhang Jie sneered twice.

Gu Qing: "..."

At Li Jing's mansion in Chang'an, Li Jing was very sensitive to some spherical and similar spherical things these days. His wife gave birth to a ball for three years and six months. She turned to look at Su Dingfang and said angrily: "When did I offend Gu Qing? Why did he spread rumors like this?"
