(The book is number one and is on the shelves... 6500 collection... It is a mule or a horse to pull it out to see. I hope there are 500 bookmarks... The guaranteed third update, one hundred subscriptions plus one update... To be honest, my heart is trembling constantly, I hope everyone can support it...!)

Wu Zetian sighed... At this time, Li Dan showed a worried expression, but soon Li Dan restrained his emotions because Li Dan knew that he could not show too much concern.

Princess Taiping asked in surprise without any scruples: "Mother... the water in Luo River has reached such a serious point?"

Wu Zetian nodded slightly and said, "Of course, everyone knows that the rain in March is as expensive as oil... But since March, Shendu has never rained again. The water level of the Luo River has dropped very seriously and cannot be irrigated at all.

Soon, the villages upstream wanted to block the water and build dams, so that their water level could rise for a section and irrigate the fields.

But in this way, the downstream villages are completely finished.

So not long ago, a large-scale armed fight occurred, killing and injuring 30 people. Although I have appointed Di Ge Lao to deal with it once and comforted both sides, it only treats the symptoms but not the root cause. If there is no water, it will be useless."

After Wu Zetian finished speaking, Ang Lee on the side smiled and said, "Grandma has been struggling with this matter recently. In fact, I just learned from Sister Wan'er that she knew that her grandmother was anxious, and Ang Lee was also anxious.

Since noon, I have been thinking about the solution...!"

"Ha...!" A sneer... Li Longji looked at Li An unhappily and said, "Then my cousin has come up with any countermeasures. If he hasn't come up with any countermeasures, I see that my cousin's concern for His Majesty is really unnecessary."

At this time, Li Longji was very unhappy. He was already very outstanding just now, but Ang Lee brought the topic to the issue of the water level of the Luo River. In Li Longji's opinion, Ang Lee was very scheming, which was because Ang Lee didn't want him to get Wu Zetian's like, so he deliberately created obstacles for himself.

So Li Longji also complained about Ang Lee without being angry.

"Yes..." After Li Longji said that, Princess Taiping on the side quickly continued: "An'er...you, you should learn the Six Arts of Gentleman well and don't think about things you can't do.

My mother has the help of the court ministers, so you don’t need your worries.”

Princess Taiping didn't say anything about Ang Lee's chance to destroy his son's performance, but she felt unhappy, so Princess Taiping also used a soft knife to Ang Lee.

"Okay... don't say anything, An'er is feeling sorry for me... and you don't know how powerful An'er is..."

Wu Zetian was still very doting on Ang Lee and touched Ang Lee's head with his hand and said, "An'er... Do whatever you want and don't worry about others, because grandma will make the decision for you.

A gentleman’s six arts are very good, but he doesn’t know how to be a gentleman’s six arts. You are also a gentleman…I am my gentleman.”

After saying that, Wu Zetian and Li Ang looked at each other warmly. Li Dan, Li Chengqi, and Xue Chongxun showed a warm smile, but Princess Taiping and others showed a taste of eating. Of course... The taste of eating was not too serious at this time, just a little jealousy. Such jealousy was not enough to make Princess Taiping and others directly opposed Ang Lee.

And at this moment... Ang Lee took out a picture from his arms and handed it to Wu Zetian and said: "Grandma... In fact, my grandson has already had a way to solve the problem that the water level in the Luo River has dropped and cannot be irrigated.

It was my grandson racking his brains and I don’t know how much hair he lost, so he came up with this kind of Wu Zhaotong car...!"

"Wu Zhaotong car..." Everyone was stunned. Princess Taiping and Li Dan came directly to Wu Zetian's table. In Wu Zetian's hand, a round object similar to a wheel appeared in front of them.

The water wheel of the barrel car is upright in the water by the river, and several small bamboo and wooden tubes are installed obliquely around the wheel, with up to 42 pipes.

Then Ang Lee introduced to Wu Zetian and others again: "Wu Zhao Tube Car is a modified Tube Car designed by me. It can use the water flow to push the main wheel; the small tubes around the wheel are filled in order, and the water is poured out to the top, and connected to a wooden trough, and introduced into the canal field.

If the hydraulic power is insufficient, human or animal power can also be used.

Its water transport components are like well trucks. There are wooden frames on top and bottom, each equipped with a wooden wheel. The wheel diameter is about four feet high on the side of the wheel rim, low in the middle, and grooves are made in the middle, making it more uneven to increase the friction between the rim and the bamboo tube.

The wheels below are half soaked in water. The two wheels are connected by bamboo ropes. The bamboo ropes are about one foot long and the distance between the bamboo tubes is about five inches. Between the upper and lower wheels, under the upper bamboo cables and bamboo tubes, they are supported by wooden frames and wooden boards to bear the weight of the bamboo tubes after they are filled with water.

The bamboo rope tied to the bamboo tube is a transmission. When the upper wheel rotates, the bamboo rope and the lower wheel rotate with each other, and the bamboo tube also goes up and down with the bamboo rope. When the bamboo tube goes down into the water, it fills up with water, and then goes up with the bamboo rope. When it reaches the height of the upper wheel, the bamboo tube invades the water into the sink, and thus circulates continuously.

It drives small bamboo tubes to hold water in a series of connections and goes up along the sink to get water from low water sources on high shores.

Not to mention that the water level of the Luo River has been slightly lowered, even if it is lowered more, this kind of Wu Zhao Tube Car can also drive the water in the Luo River."

"Okay...Okay...Okay...!" After hearing Ang Lee's introduction to Wu Zhao Tongche, Wu Zetian said three words "good" happily... and then he held Ang Lee in his arms and smiled: "My Qilin grandson, my Qilin grandson... What do you want me to reward you? I wish I could give you everything I have.

I have An'er Qilin grandson, which is really my greatest gratitude."

Wu Zetian's praise is not because of his pampering... it is because the Wu Zhaotong car created by Ang Lee, which is definitely a thing of the same level as Qu Yuanli.

Hundreds of years, thousands of years later... The poem "Bamboo Car" in "The Collection of Jushishu" by Zhang Xiaoxiang of the Southern Song Dynasty says: "Turn this *** and save you from drought every year." "The old farmer didn't know how to use it, and he instantly 1,000 acres."

Since the Southern Song Dynasty, cylindrical trucks have been continuously improved during use and have gradually been promoted and popularized.

During the Ming and Qing Dynasties, twelve twelve can be seen in all counties in Ankang. Local chronicles are mostly recorded. Place names that have been used so far can be found in the past.

On the banks of the Huangyang River in Yingfeng Township, Hanbin District, you can still see the charm of the trolleys. While spraying beads and jade, they have also become a beautiful scenery for people to visit.

"Excellent ideas...the Great Zhou Qilin...!" Li Dan also followed her side and praised her.

When Wu Zetian heard her son's praise for her grandson, she was very satisfied. The first time she felt that her son was still good...but Li Longji, Princess Taiping showed a frown expression slightly.

Of course, these small expressions flashed by. Soon, Princess Taiping and Li Longji began to praise Ang Lee at the first time.

Shangguan Wan'er stood aside and looked at Ang Lee with some admiration. To be honest, today's three poems have already made Shangguan Wan'er amazed at Ang Lee, and now it is another bus.

Even a talented woman admires Ang Lee in awe.

And such admiration also brought Ang Lee and Shangguan Wan'er's hearts closer, and this approach brought Zhou Xing one step closer to death.
