A post-apocalyptic female soul travels back to the War of Resistance against Japan

"Another thing is that I've already thought of this: I'll put the pipes I took out into the ditch and install a few sewer openings. If this kind of flood happens again, the water will flow into the river through the sewers."

Shi Mobai nodded in understanding. "Oh, so there are so many intricacies here. Senior Sister Lin, you know so much."

Liu Haoyang also said, "Junior sister not only knows a lot, but also has a complete set of knowledge! Otherwise, no matter how much she knows, she wouldn't be able to complete this idea without all the knowledge."

Cheng Ying said proudly, "Hehe, I'm a master at collecting things from all walks of life. I have everything here."

Their commotion quickly alerted the Emperor, who then led several ministers to the area, where they saw the unusual number of vehicles.

And those tubular objects whose purpose I didn't know, I asked in bewilderment:

"What have you guys come up with this time? What are they for?"

To explain things more clearly, Cheng Ying quickly printed out a drawing from her spatial storage, made several copies, and handed them to the Emperor and the others.

"Uncle, it's a long story. Here are some blueprints. You'll understand their purpose once you see them."

“I left three people behind. They helped us dig the ditches. Those vehicles were also used when digging the ditches, and all three of them can drive them.”

"And some of the pipes over there were also used when the ditches were built."

"If there's anything you don't understand, you can ask these three. Uncle Huang and the other two are the same as the robots in the apartment, only more intelligent."

"Do you understand what I'm saying?"

"You can communicate normally, but it would be best to send some people to help them in case others don't understand the situation and cause trouble."

"The location for digging the ditches must be as close as possible to the outer perimeter of Xingyao Mansion. You can discuss this with each other."

"Before I leave, I'll have my people pack up all the heavy equipment and pipes. We can ask them for them again when we need them."

After Cheng Ying rattled off some necessary points, Emperor Ye Shengtang and several ministers nodded in agreement.

After the emperor and several ministers gathered together to study the blueprint, they realized the brilliance of the design.

The more Su Huaijin, a Grand Secretary of the Wenhua Hall, looked, the brighter his eyes became, and he suddenly said:

"Your Majesty, the pipes designed in this blueprint can be installed in the city. Rainwater that accumulates in the city during heavy rains can then be drained through these pipes."

"Unfortunately, the workload is just too large."

As Su Huaijin spoke, he rejected his own ideas, shaking his head and frowning, as if he were very troubled.

However, Cheng Ying and the others were quite surprised by his idea. The ancients were indeed very clever; they had already thought of underground urban planning based on this matter.

Ye Wuhen saw that it was almost time, so he informed the Emperor and the others:

"Brother, we'll leave things to you here. My fellow disciples and I will head to Xingyao Mansion now."

"By the way, the bus will be reserved for you. If you want to go and take a look, you can take the bus there!"

"That car is fast, so you can make it back for lunch if you come back around lunchtime."

"If you need to feed the people at the canal digging site, you can set up a shed nearby and cook for them on the spot, or you can cook here and then deliver it over. Anyway, there are buses available, so it's convenient."

After looking around, there was nothing else to explain, so Cheng Ying took out an eight-seater hovercar.

Ye Shengtang and Duke Anguo only came to their senses when they saw that everyone had gotten into the carriage and was about to leave.

So he quickly instructed, "You guys must prioritize your own safety. If you can't finish the task, it's okay, we'll think of another way."

Ye Wuhen waved his hand and said, "Don't worry! We're leaving now, Your Majesty and Duke Anguo. I'll take good care of them."

After they finished speaking, they waved, and the car sped away.

Ye Shengtang, Duke Anguo, Prime Minister Li, and several Grand Secretaries watched the group disappear into the distance, their carriages soon vanishing from sight, and couldn't help but feel a deep sense of emotion.

Traveling with these children this time has not only broadened my horizons, but also shattered many of my previous preconceived notions.

Ye Shengtang roused himself, and after making some arrangements for things here, they boarded the bus one after another, ready to go together to find a suitable location for digging a canal.

Of course, this group also included the three people Cheng Ying left behind, as well as the vehicles and everything else they needed that were stored in their personal spatial storage.

The emperor and his men wanted to find a location to dig a canal and then move the pipes, excavators, dump trucks, and other equipment there first.

Their thought was that since the children were so capable, they, as elders, shouldn't hold them back.

……

Everything is being arranged in an orderly manner, and everything they do is to strive for the peace and happiness of the people in this land.
