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

Nangong Hong pointed to the map and said, "Sister Wang, if this branch of the river is modified like this, at least half of the people will lack water, including Runan City. They will have to rely on wells for water in the future."

This branch is semi-circular, branching off from the Mao'er River, then circling Runan City before flowing back into the Mao'er River.

The river she's drawing on the map just happens to avoid Runan City.

"For now, this is the only way." Nangong Wu pointed at the map. "We'll use explosives to break through this area, divert the water, and ensure the people in this region have water to drink and for irrigation."

The climate here is mild, and crops can still be grown in the fields during winter. With this river, the people can irrigate their vegetables.

"So we'll have to build two dikes then." Nangong Xiao frowned slightly.

They've already filled in the moat; once water is released from above, it will have to be diverted below.

Nangong Wu nodded: "Yes, we can divide into three groups and build the two dikes at the same time. It can be completed in a few days."

As for the river channel that will be diverted, we can blast it open with explosives and then have the local people dig it up. We only need to leave a few people here to supervise the work, so it won't delay the projects in the city.

"Since the route here needs to be changed, I can lead my troops to supervise the construction," Cao Bin said.

All you need to do is keep an eye on people and move the blasted rocks away, preventing them from cheating or taking shortcuts. No special skills are required.

Nangong Hong spoke again: "Have you noticed that the flood that inundated Runan City this time was not entirely caused by the water flowing down from the Mao'er River, but also by floods flowing down from various other places?"

"Yes." Nangong Wu looked at him with approval. "So, we still need to take precautions against floods. I've surveyed the surrounding terrain. Runan City is located in a low-lying area. After the continuous torrential rains caused flash floods, the water flowed downhill, which is why Runan City was flooded."

"Sister, how do you plan to solve this problem? Should we block all the mountain streams from which the floodwaters flow?" Nangong Xiao asked.

"That's true, but we need to intercept them in a planned way." Nangong Wu pointed to a red circle again.

"The biggest flood outlet this time is here. We can build a reservoir here, and the water can be stored here during the next high-water season."

"Wonderful!" Ji Hongfei clapped his hands and exclaimed.

Cao Bin, Su Siyan, Li Zhan, and the others nodded in agreement.

"In that case, let's start by building the dike tomorrow." Nangong Xiao pondered for a moment, then added, "I'll write a letter to General Zhou later, asking him to bring some men to help."

They have good relations with the Southern Qi Kingdom, so there won't be any trouble on the border. They don't need so many people to guard it. It would be better to send some soldiers over to help dismantle the old city walls.

After everyone had discussed the matter, they went their separate ways.

Ji Hongfei went outside and saw Qiao Xiangqing standing outside the door. He smiled and teased, "Miss Qiao, you've brought dinner to the young master again."

Upon hearing this, Nangong Wu looked over and saw Qiao Xiangqing standing outside the door carrying a food box.

"Brother, so it was Miss Qiao taking care of you?"

Nangong Xiao paused in his teacup-holding hand, glanced at her, and said, "Don't be too quick-witted."

Nangong Wu leaned close to his ear and said, "Brother, Miss Qiao is a nice person, beautiful and kind-hearted. She could be my sister-in-law."

Nangong Xiao's ears turned slightly red. "I'll talk about my marriage after I marry you off."

"Alright!" Nangong Wu walked to the door. "Miss Qiao, you've arrived?"

Qiao Xiangqing had just kicked Ji Hongfei when she heard her words and turned around. "Princess, I heard you were back, so I made a few dishes and brought them over. I hope you like them."

"Is this for me?" Nangong Wu took the food box from her hand. "Then I must try Miss Qiao's cooking."

"I made some dishes from my hometown. I don't know if they'll suit your taste." Qiao Xiangqing followed her in and naturally started tidying up the things on the table.

Nangong Wu's gaze swept back and forth between the two, sensing that there was something going on between them.

The older brother grew up in the martial arts world, while Qiao Xiangqing is the daughter of the leader of the Kunlun Sect. Both are people from the martial arts world, so they may have common topics to talk about.

"Ahem..." Nangong Xiao felt her "ill-intentioned" gaze and coughed twice. "Little sister, Miss Qiao's cooking is quite good."

"Really? Brother, you rarely praise anyone other than your sister. It seems Miss Qiao is a very good cook."

Upon hearing this, Qiao Xiangqing quickly waved her hand, "Nothing special, just some ordinary home-style dishes."

"Let me take a look." Nangong Wu placed the food box on the table, opened the lid, and the aroma of the food wafted out.

"Wow! Braised mandarin fish!" Nangong Wu brought out the dish. "It looks and smells amazing! I never expected Miss Qiao to have such good cooking skills. Are we going to be lucky to have such a delicious meal from now on!"

Qiao Xiangqing was a little embarrassed by the praise. "Princess, if you like it, I will make it for you in the future."

"That won't do." Nangong Wu quickly waved her hand. "You're the young lady of the Kunlun Sect, how can you cook for me? Besides, I have Eileen with me, so there's no need to trouble you, but..."

She glanced at Nangong Xiao, "But my brother has no one to take care of him. When you're cooking, Miss Qiao, could you please cook a little extra for him? I would be extremely grateful!"

Seeing that she was getting more and more outrageous, Nangong Xiao quickly came over and said, "Let's eat! We'll be busy tomorrow, so go back and rest early after you finish eating."

"Then I'll go back now! Eileen has probably already prepared dinner for me, so let's not waste it. You guys enjoy your meal." Nangong Wu said and left.

Their father was waiting for them to eat in the space. Since Qiao Xiangqing had brought the food, she decided to go back to the space alone to have dinner with her father.

"Princess, why are you leaving before we've even eaten? I made so many dishes..." Qiao Xiangqing called after her.

Nangong Wu returned to her room, closed the door, and slipped into her spatial dimension.

Eileen had already set the food on the table.

"Master, this space really only replenishes the things brought from the previous life. The steel bars, cement, and even sand have been replenished, so there's no need to worry about not having enough steel bars."

Nangong Wu was also very happy to hear that, "That's good."

"Wuwu, is there anything your father can do to help you?" Huo Jing also wanted to do something.

"Father, Runan City is a mixed bag now. You should stay here and be a tutor to the children." Nangong Wu absolutely could not let her father go out and take risks.

"Fine!" Huo Jing had no choice but to give up.

The children's studies shouldn't be neglected, so let's teach them to read in this space!

The next day, they stopped the foundation work and went to build the dam.

But the old city walls are still being demolished, and tens of thousands of people are standing on the walls.

Five days later, the two dikes were successfully constructed, the foundations were excavated, reinforced concrete was poured, and spillways (middle and bottom holes) were left.

During this period, Nangong Wu led people to excavate the river channel, blasting open a natural barrier of about 300 meters. After the channel was opened, the river water could flow through without having to pass through the original moat of Runan City.
