With a warehouse full of supplies, I stood alone as king in this chaotic world, gun in hand.

"There aren't many good stones left. You can keep them if you want." Nangong Wu smiled at him.

"Brother, when we rebuild the city wall, we won't need these stones and rammed earth."

She also went to inspect the city walls of Runan.

The base is about 10-12 meters wide and the top is 6-7 meters wide. Like other cities, it is built using the "inner earth and outer brick" method. The inner earth is rammed to bear the load, and the outer brick is wrapped to prevent wind and rain.

However, only a small portion of the Runan city wall was covered with bricks; the outer wall was made of stone instead of bricks, and most of the upper half of the wall was made of rammed earth.

"Without stones and rammed earth?" Nangong Xiao was taken aback. "You want to use bricks all the time? That's possible. The technology for making bricks is very good now. We can just open more brick kilns."

"We don't need bricks either; that would be too time-consuming, laborious, and not very sturdy," Nangong Wu said with a smile, shaking her head.

"Not even bricks?" Nangong Xiao was first surprised, then puzzled. "Then what will we use?"

If you don't use stones and bricks, and you don't even use rammed earth, then what can you use? He was very puzzled.

I know this younger sister is very capable, with supernatural abilities and magic, but no matter how capable she is, she can only conjure up existing things, and she can't conjure up a city wall that stretches for dozens of miles!

If that's true, then she's not human, she's a deity!

"Brother, you'll find out how it will be built when the time comes!" Nangong Wu gave him a mysterious smile.

In the past, skyscrapers were built with reinforced concrete. Who would still use ancient methods like bricks, stones, and rammed earth?

Her space contains tools such as a mixer, a transport vehicle, a glass edge-pulling machine, a cutting machine, and a stone saw.

In her previous life, when the apocalypse came, she traveled to various major cities. These things were everywhere on construction sites, and she collected them all into her space, thinking that they would definitely be useful in the future.

Her space is infinitely large, and she collects anything useful she sees, all of which is just a matter of a thought.

There is plenty of natural sand here, so we'll build roads first, the kind of roads that can accommodate large trucks.

There's a lot of cement in the space, but that's far from enough to build a modern city. We also need to build a cement factory. She knows the formula, but Aiqi and Erin are super brains and know even more than she does.

"Then I'll wait and see, brother." Nangong Xiao couldn't help but feel excited.

To build a city wall without using stones and bricks, or even rammed earth, makes me eager to know how she does it.

"Your Highness, we'll wait and see!" Ji Hongfei was very excited. He was glad that he had stubbornly insisted on following Nangong Wu and had finally caught up with his destined benefactor.

"Just you wait!" Nangong Wu turned around and smiled at them. "You definitely won't regret following me."

Several subordinates hurriedly bowed.

"Your Highness possesses lofty ambitions and a heart that embraces the world; you are a blessing to the people. We swear to follow Your Highness to the death, even if it means going through fire and water!"

"It's like going through fire and water. It's not that serious." Nangong Wu couldn't help but smile.

How could we possibly send her through fire and water for those who follow her?

"Building a city is still a long way off. Right now, we need to deal with this disaster and prevent the city from being flooded again."

"Your Highness," Cao Bin said, "this humble general believes the biggest reason is the moat."

"The moat is fed by water from the Mao'er River. The Mao'er River is not large, and its end flows into the Li River."

Runan City is situated in a relatively low-lying area, and due to continuous heavy rains, the Mao'er River has swelled, causing floodwaters to flow into the Runan City area along the moat.

"Since we've been drawing water from the Mao'er River all along..."

"That makes sense." Nangong Wu nodded. "We won't need the moat anymore. We'll just divert the floodwaters after they recede!"

Let's go and observe again today to see where the largest floodwaters, besides the Mao'er River, are coming from. Then we'll figure out a way to divert the water away.

The area is surrounded by water for dozens of miles. We need to find a way to divert the water out, otherwise we don’t know how long we’ll have to wait for it to run out on its own.

Nangong Wu drove the motorboat away and observed the terrain around Runan City.

"Help! Help us!" Suddenly, a cry for help rang out.

The sound seemed a bit far away, and Nangong Wu couldn't hear it clearly, so she stopped the speedboat and looked for the source of the distress call.

"Your Highness, the sound is coming from that mountain!" Ji Hongfei pointed to the mountain on the left.

"They might be villagers from nearby," Cao Bin said to Nangong Wu and Nangong Xiao.

"Your Highness, there used to be many villages around Runan City, but with the continuous torrential rains, they probably took shelter in the mountains!"

Nangong Wu and Nangong Xiao took out their binoculars to check and indeed saw three people standing on a large blue stone slab waving at them.

"Let's go take a look." Nangong Wu drove the speedboat towards the mountain.

When the three people on the mountain saw them pass by, they all ran down the mountain.

When Nangong Wu drove the speedboat to the edge of the mountain, the three people got off.

There were three men, between twenty and forty years old, wearing straw raincoats and carrying bamboo hats.

When villager A saw Cao Bin in military uniform, he shouted:

"Sir, please save us!"

"Where are you from? What are you doing here?" Cao Bin asked, eyeing them warily.

The most bandits were in Jianggang Prefecture and Runan Prefecture, so they had to be on guard.

"We are from Blackstone Village." Villager A also noticed their wariness, took out a package from his pocket, opened the package, and inside was a folded piece of paper.

He handed the paper to Cao Bin, "Sir, I used to be a江湖 (jianghu, a term referring to the world of martial arts and outlaws) man. This is a travel permit I obtained from the government. Please take a look."

Cao Bin took the paper and saw that it was indeed a travel permit issued by the government, stamped with the official seal of the Runan Prefecture, indicating that the person was a villager from Heishi Village.

"Is it just the three of you?" Nangong Wu asked.

"Also, because of the sudden flood, all of our more than two hundred people from Black Stone Village have fled to a cave on this mountain," said Villager A.

"Do you have anything to eat right now?" Nangong Xiao asked them.

"We still have food, enough to last for a month at most, but the floodwaters won't recede in a month. We hope the government can save us." Villager A knelt down before them.

"We know about your situation! We will rescue you." Nangong Wu looked around. "You can stay here for now. We will bring you supplies by noon tomorrow."

"Thank you so much!"

The three villagers all knelt down to express their gratitude.

"Remember this, these are the heir of the Prince of Zhenyuan and the Princess of Runing. It was these two princes who saved the entire city of Runan!" Cao Bin told them.

The three villagers were all stunned when they heard this.

"What? They're the heir and princess from the entire clan of Liang Zheng, the corrupt official who killed the dog?"

"We'll bring the things to you tomorrow," Nangong Wu said before turning and returning to the speedboat.

"Thank you, Your Highness, and Your Highness!"
