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

Chapter 447 Yu Chihuan Built a Water Pump at Home and Alarmed Li Er
Suzaku Main Street, Yuchi's house!

That morning, when Yuchihuan returned home, he ordered the craftsmen at home to build the well cover, and then installed a water pump on it.

Seeing that Yu Chihuan hadn't eaten yet, the eldest lady dragged him into the living room for dinner.

This time, Yuchihuan did not refuse the arrangement of the eldest lady, and obediently ate enough before going to tinker with the well.

In order to make the cement cover of the well solidify as soon as possible, Yuchihuan used quick-drying cement today.

An hour later, a completely new well appeared in front of everyone.

And the concrete pier designed by Yuchihuan also solidified!

The water pump inside the concrete pier has been secured and ready to pump water.

Yu Chihuan first poured a ladle of clean water at the outlet of the water pump, and then yanked the iron handle of the water pump violently!

creak!creak!
After a while, the water pump pumped up the well water below the well, and then the well water flowed into the barrel continuously.

The well water was a bit muddy at the beginning, but as the soil in the water pipes was cleaned up, the well water coming out of the pump became crystal clear!

Yuchi Huan secretly breathed a sigh of relief when he saw that there was no problem with the water brought up by the water pump.

Next, Yuchihuan filled three buckets in a row before stopping in satisfaction.

Yuchihuan had used many manual water pumps before, but the water output was still not as good as the pumps produced by the system.

"Mother, in the future, you can come here to fetch water directly!"

Yuchihuan is very satisfied with the water pump produced by the system.

The eldest lady also tried the water pump afterwards, and she was very satisfied with the result.

The lady was both surprised and delighted and said: "Huan'er, I didn't expect that the water dispenser you invented is so useful!"

Yu Chihuan smiled and said, "Mother, this is actually similar to the principle of the water wheel!"

Da Furen said with emotion: "Huan'er, did you invent this thing?"

The water pump produced by the system has an instruction manual, so it is not difficult for Yuchihuan to imitate it.

Yu Chihuan thought for a moment, nodded and said: "Mother, this manual water pump was indeed invented by the child!"

The lady smiled and said, "Huan'er, the people of the Tang Dynasty will have this water pump in the future, so they won't have to break the ice to fetch water in winter!"

Yuchi Huan has already installed the water pump of Yuchi's house. Today's task is completed, and he can go to Zhongshu Province to be on duty with peace of mind.

The eldest lady stayed at home to fetch water and wash the dishes, so busy that her feet never touched the floor.

But the lady is having fun!
And among the servants of Yuchi's family, there are quite a few spies, among them are the spies of the Secret Disc Division.

So not long after Yuchi Huan left the door of the house, a servant of Yuchi's family hurried out of Cheng Yaojin's house and reported to Li Erfeng.

When Yu Chihuan returned to Zhongshu Province, he quietly corrected the memorial.

On the other side, the eldest grandson Shunde felt uncomfortable, because he could no longer accept money from others and recommended others to be officials.

The most important thing is that Changsun Wuji has clearly informed Changsun Shunde that he is still in the Ministry of History for one day, so he will prevent the person recommended by Changsun Shunde from becoming an official.

This is a killer move for Changsun Shunde!
Because of this, Changsun Shunde did not dare to accept money.

Yuchihuan is also happy to see this happen.

The reputation of Zhongshu Province needs to be maintained by Yu Chihuan and Changsun Shunde.

……

Tai Chi Palace, Ganlu Palace!
Imperial study room!
In the afternoon, Li Er woke up from his afternoon nap and went to the imperial study to correct the courtiers' memorial.

Suddenly, Zhao Deyan, the head of the Secret Disc Division, hurried into the imperial study from outside and said, "Your Majesty, the Secret Disc Division's spies found something that can pump water at Yuchi's house today!"

Li Er put down his vermilion pen, stared at Zhao Deyan, and asked curiously, "Zhao Deyan, Yuchi's family has a water pump that can pump water, what's all the fuss about?"

The water rolling wheel was invented by Yuchihuan, and it has been used to irrigate farmland in various parts of the Tang Dynasty, benefiting the country and the people!
So when Zhao Deyan talked about pumping water, Li Er immediately thought of the water wheel.

"Your Majesty, the one in Yuchi's house is not a water roller, but a water pump installed on the well, which is easier to use than a water roller!"

Zhao Deyan didn't know whether to laugh or cry. As the Water Superintendent of the Tang Dynasty, he was in charge of all the water-related rivers and lakes in the Tang Dynasty, so he must know the existence of the water wheel.

Li Er asked curiously, "Zhao Deyan, what is a water pump?"

Zhao Deyan explained: "Your Majesty, I heard that the pump invented by Yuchihuan can directly pump up well water, which is more convenient than a water wheel and suitable for household use!"

Li Errao said with interest: "Come here, bring Yu Chihuan to the imperial study to see me!"

"Slaves follow orders!"

The prince didn't dare to neglect, and immediately went to the Ministry of Zhongshu to deliver the decree.

"Your Majesty, if the young Prime Minister Yuchi sees the humble minister in the imperial study, I'm afraid it will be bad!"

Zhao Deyan's face turned pale with shock, and Li Er's actions were too straightforward.

If Yu Chihuan saw Zhao Deyan, the head of the secret disk department, in the imperial study, he must understand that the water pump in Yuchi's house must have been tipped off by Zhao Deyan.

So Zhao Deyan wants to leave now!
Li Er also understood Zhao Deyan's thoughts, he snorted coldly and said, "Zhao Deyan, you don't change your face in front of Jieli Khan, why are you so afraid of little Yuchi?"

Zhao Deyan couldn't laugh or cry: "Your Majesty, the last time I was thrown out of the house by Prime Minister Yuchi because I frightened Madam Yuchi, I was really afraid of his revenge!"

Li Er thought for a moment, then waved his hand and said, "Forget it, Zhao Deyan, step back!"

"The minister obeys the order!"

Zhao Deyan immediately ran out of the imperial study room without looking back as if he was granted an amnesty.

"Is Xiao Yuchi so scary? Zhao Deyan, who made the nobles of Chang'an City fearful, can't be avoided so much?"

Li Er was dumbfounded, startled by the figure of Zhao Deyan fleeing in embarrassment.

Zhao Deyan, the majestic spy chief of the Tang Dynasty, is actually afraid of the 11-year-old Yuchihuan!
Li Er thought it was a bit funny.

After half a stick of incense, Yu Chihuan was finally brought into the imperial study by the prince.

When Yu Chihuan saw Li Er, he immediately raised his hands and said, "My minister sees Your Majesty!"

Li Er stared at Yuchi Huan and asked: "Little Yuchi, I heard that you don't need a bucket to fetch water from your well now, is there such a thing?"

Yuchi Huan knew that the installation of the water pump at Yuchi's house would definitely not be hidden from Li Er, so he was already mentally prepared for it!

However, the water pump had just been installed in Yuchi's house, and Li Er knew it, and the efficiency of Secret Disc Division was too high!
Now that Li Er already knew about this, Yu Chihuan couldn't continue to hide it.

Yuchihuan cupped his hands and said, "Your Majesty, I installed a water pump in the well at home today, so that water can be brought up directly without throwing buckets into the well to fetch water!"

Li Erlong said with great joy: "Xiao Yuchi, there is also a well in my Ganlu Hall, can you help me install a water pump next to the well today?"

"Your Majesty, the installation of the water pump requires concrete and steel reinforcement!"

Yuchihuan did not refuse Li Er's request, but the raw materials such as cement and steel bars must be provided by Li Er.

Li Er said indifferently: "Xiao Yuchi, I will transfer the concrete and steel bars to the palace for you immediately!"

Yu Chihuan continued: "Your Majesty, I still need a few masons to help build the well cover!"

Li Er laughed heartily and said: "Come here, order the Ministry of Industry to allocate ten stones of cement, ten stones of steel bars, and a hundred craftsmen into the palace for backup!"

"Here!"

The prince did not dare to be negligent, and immediately ran out of the imperial study room to convey Li Erkou's instructions,
"Little Yuchi, is it okay for me to make such an arrangement?"

Li Er then asked Yu Chihuan with a smile.

Yu Chihuan nodded and said yes: "Your Majesty, with the help of a hundred craftsmen, I have no problem repairing ten pumps in the well today!"

Li Er gave up and said: "Xiao Yuchi, let's repair a water pump in Ganlu Palace today!"

"The minister obeys the order!"

Yu Chihuan nodded and stopped talking.

After a stick of incense, Wang Gonggong finally returned to Ganlu Hall with a hundred craftsmen.

Cement and steel bars were also brought in by craftsmen.

Yu Chihuan then bid farewell to Li Er and went to the well in the backyard of Ganlu Hall to build a pump!
