Datang: An eight-year-old master of the bar, he gave everyone a blow at the beginning

Chapter 464 Wu Meiniang finally developed quick-drying cement
The letter sent by Liu Rengui to the Ministry of War was also sent to the Ministry of Education, and presented in front of Yuchihuan!
After reading Liu Rengui's Flying Pigeon Biography, Yu Chihuan secretly breathed a sigh of relief: "It seems that the globe did not trick me, and it can indeed replace the GPS!"

In fact, when Yu Chihuan gave the globe to Liu Rengui, he didn't have enough confidence.

After all, Yuchi Huan had never used a globe to navigate the sea.

Who knows if the globe has the possibility of cheating?
But this time Liu Rengui helped Yuchihuan lie down, so Yuchihuan can use the globe with confidence in the future.

"I wonder if Liu Rengui brought back coconuts this time?"

Yuchihuan has a grudge about the coconuts grown in coastal areas.

Coconuts can be used not only to make coconut milk, but also to make coconut candies!

Coconut oil can even be pressed from the coconut meat.

Coconut oil also has beauty benefits in later generations.

The most important thing is that Yuchihuan hasn't eaten coconut for a long time!

Although some foods don’t need to be eaten every day, it’s still nice to eat them once in a while.

"I hope Liu Rengui won't let me down, otherwise I'll beat him up!"

Yuchihuan has high hopes for Liu Rengui.

Afterwards, Yuchihuan left Liu Rengui's letter in Zhongshu Province for archiving.

Changsun Shunde was as happy as an old child when he learned that Liu Rengui had carried millions of stones of guano sediment back to Datang.

"Little Prime Minister Yuchi, if the old man asks His Majesty for a hundred stones of guano to fertilize the field, do you think His Majesty will agree to it?"

The eldest grandson Shunde's family has a lot of Yongye farms, so they are in great need of guano fertilizer fields.

Yu Chihuan thought for a while, then shook his head and said, "Eldest Sun Shunde, you and I are both relatives, with a big family and a big business. I'm afraid His Majesty won't distribute bird droppings to us for farming first!"

Changsun Shunde said disappointedly: "Young Prime Minister Yuchi, so the 100 million stones of guano transported back to the Tang Dynasty by the Zhongzhou Navy have no chance of us?"

Yu Chihuan nodded and said yes: "Changsun Shunde, you guessed it right, I think so too."

Seeing Yuchi Huan's indifferent attitude, Changsun Shunde said in surprise: "Little Prime Minister Yuchi, Your Majesty treats one more than another, why are you so calm?"

Yu Chihuan smiled and said: "Eldest Sun Shunde, I am not short of money, let alone food, why should I be in a hurry?"

After hearing Yu Chihuan's words, Changsun Shunde was immediately speechless.

"Little Prime Minister Yuchi, I know that you still have 35 coins kept in Changle Palace. You are richer than this old man. You really don't care about mere bird droppings!"

Changsun Shunde thought for a moment, and felt that he was not as rich as Yuchihuan, so he was dissatisfied.

When Yu Chihuan heard Changsun Shunde say this, he shook his head and said: "Changsun Shunde, the reason why you even grab bird droppings from the common people is because you are greedy for money, and I regard money as dung!"

Changsun Shunde quibbled: "Young Prime Minister Yuchi, where is the old man greedy for money?"

Yu Chihuan sighed and said: "Eldest Sun Shunde, if His Majesty hadn't warned you, you might still be collecting money from someone and recommending him to become an official!"

"The old man is gone!"

Changsun Shunde's thoughts were exposed by Yuchihuan, and he returned home in a rage.

Yu Chihuan stared at the elderly figure of Changsun Shunde, shook his head and said, "Changsun Shunde has already stepped into the coffin with half of his foot, leaving behind a wealth of wealth that can't be spent? Why are you so greedy for money?"

Fortunately, Changsun Shunde was deaf and couldn't hear Yuchihuan's muttering to himself, otherwise he would vomit blood on the spot.

But the officials of the Zhongshu Province next door to Yuchihuan heard it clearly, and they agreed with Yuchihuan's words very much.

The eldest grandson Shunde was insatiable in the Tang court!
If Changsun Shunde was not the relative uncle of Empress Changsun, and with the guarantee of Changsun Wuji, Li Er would have dismissed him from office long ago.

The most infuriating thing is that Changsun Shunde also made crooked ideas about the money that Li Er rewarded the officials of Zhongshu Province.

The officials of Zhongshu Province dare not speak out against the elder Sun Shunde!
It wasn't until Yuchihuan became the master of Zhongshu senior official Sun Shunde that he restrained himself a little.

It is closely related to Yuchihuan's ability to gain the respect of the officials of the Ministry of Education in a short period of time.

Now Changsun Shunde has been overwhelmed by Yuchihuan in Zhongshu Province!

The eldest Sun Shunde returned to his seat and began to correct the memorial!
Since Li Er ordered Changsun Wuji to warn Changsun Shunde not to sell his official status, Changsun Shunde restrained himself.

However, Changsun Shunde's only joy of collecting money is gone, and his energy is not as good as before.

……

The Ministry of Industry will be the supervisor!

At this moment, Wu Meiniang is researching quick-drying cement in her workshop.

The task of the astronomical telescope has now been entrusted to Yan Liben to manufacture.

The reason why quick-drying cement can dry quickly is that some expansion agents are added to the quick-drying cement, which is conducive to the volatilization of water.

Yu Chihuan didn't know that there was something in Datang that had an expansion effect, so he ordered Wu Meiniang to do experiments a little bit.

In order to research the quick-drying cement as soon as possible, Wu Meiniang added all the expanding things in the entire Chang'an city into the cement and stirred it!
After more than ten days and thousands of failed experiments, Wu Meiniang finally found a mineral that can make the cement expand and volatilize rapidly.

As for the name of this substance, Wu Meiniang didn't know either.

So Wu Meiniang named this substance expansion agent!
Just this afternoon, Wu Meiniang finally used the latest quick-drying cement to seal the mouse hole in the workshop!
Although the effect of quick-drying cement is not as good as the quick-drying cement given to Wu Meiniang by Captain Chihuan, Wu Meiniang is already satisfied.

Wu Meiniang then told the good news to the master craftsman Yan Liben.

After Yan Liben verified that the quick-drying cement was indeed effective, he immediately wrote a book and wrote it to Li Er.

The main use of quick-drying cement is to repair important buildings such as dams and tunnels.

Quick-drying cement is very useful!
However, it is better to use ordinary cement to build brick walls.

Otherwise, the quick-drying cement that has just been mixed will solidify and cannot be used to build walls, so it will be invalid.

"I want to tell the good news to the teacher!"

Wu Meiniang also volunteered to go to Zhongshu Province to announce the good news.

The Ministry of Industry will be supervised outside the six departments of the three provinces of the Taiji Palace.

The Zhongshu Province is near the Ganlu Hall, so the prison is a little far away from the Zhongshu Province.

After a stick of incense, Wu Meiniang arrived at Zhongshu Province!
The official on duty of Zhongshu Province immediately reported to Yuchihuan that Wu Meiniang asked to see her.

Yuchihuan immediately ordered Wu Meiniang to come in.

"The student has seen the teacher!"

When Wu Meiniang stepped into Zhongshu Province, she saluted Yuchihuan with a smile on her face.

Seeing Wu Meiniang in a good mood, Yuchihuan smiled and said, "Meiniang, is your quick-drying cement research done?"

Recently, Yuchihuan handed over the task of developing quick-drying cement to Wu Meiniang, and Wu Meiniang has been frowning.

And Wu Meiniang came to Zhongshu Province to look for Yuchihuan with a smile on her face today.

Yuchihuan guessed at random that Wu Meiniang must have developed quick-drying cement.

"Teacher, the students have indeed successfully developed quick-drying cement today!"

Wu Meiniang's thoughts were exposed by Yu Chihuan, and she immediately blushed.

Yu Chihuan immediately congratulated Wu Meiniang, saying: "Meiniang, congratulations to you for successfully developing quick-drying cement!"
