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

"Okay," Nangong Wu agreed with a smile. "After the fireworks are over, we'll set off sky rockets, but your father will have to do it for you."

"I know, I know," Nangong Xi interjected. "Mother said that setting off firecrackers can accidentally hurt people, so Father has to help us set them off."

"By the way, that's why you can't put it out yourselves," Bei Chenyan said.

"Bang bang bang..."

Clusters of fireworks bloomed in the sky.

"Farewell to the old year, welcome the new"

Happy Chinese New Year!

Happy New Year!

The appearance of these words in the sky elicited gasps of amazement, who exclaimed how amazing it was.

The fireworks lasted for more than 25 minutes, or even 30 minutes, before they finally stopped.

Many people were still not satisfied.

"Mother, let's go set off firecrackers." Nangong Xi held Nangong Wu's hand.

"Let's go! Let's set off some skyrockets." Bei Chenyan stood up and said to Huo Jing and Nangong Xiao:

"Father-in-law, Your Highness, please excuse us for a moment."

"Go!" Huo Jing nodded.

Father-in-law? Nangong Xiao was stunned.

Bei Chenyan actually called his father "father-in-law"? Could it be that his sister's marriage to the Crown Prince has been arranged?

Otherwise, how could Bei Chenyan dare to call him father-in-law?

He knew that his father had gone to the Southern Qi Kingdom twice with his sister, and it must have been for his sister's marriage.

After Bei Chenyan and Nangong Wu left with the three children, he whispered to Huo Jing, "Father, is my sister willing to marry Bei Chenyan?"

"Yes, it was Emperor Nanqi who brought it up first. Bei Chenyan is a good person and the biological father of three children. Wuwu can't stay unmarried for the rest of her life, so I, as her father, agreed." Huo Jing said calmly.

His daughter had always been reluctant to talk about marriage, and he had never pressured her.

But ever since he heard from Master Xuanwei that his daughter and Beichen Yan were destined to be together, he didn't want his daughter to waste her time like this. If she didn't go to see Emperor Nanqi, given her cold-hearted nature, she might not be willing to get married for three to five years.

Fortunately, Emperor Nanqi took the initiative to bring up the marriage of the two children first, showing his sincerity.

"That's wonderful. The three children finally have a complete family." Nangong Xiao looked at his sister's harmonious family of five in the distance and felt happy for them.

Actually, he also thought highly of Bei Chenyan.

The dinner party lasted until very late that evening.

In the following days, Bei Chenyan spent time with his three children in Runan City, discussing the future development of Runan City with them.

They had originally agreed to go back on the fourth day of the lunar new year, but when he heard from Nangong Wu that they were going to deliver grain to the Zhenyuan army on the sixth day, he stayed an extra day. On the fifth day, they had lunch with Huo Jing and Nangong Xiao, and then the family flew to Nanqi Kingdom.

Huo Jing did not go with them this time.

They returned to the Southern Qi Kingdom before nightfall.

The next morning, Nangong Wu gave Emperor Nanqi and Empress Wan another examination.

Because after this visit, it might take another month before I can come back.

She and her three children had lunch with the Emperor and Empress, and then flew north to deliver grain to the Zhenyuan army.

The army has rested for eight days and will break camp and march in two days.

After finding Dajun, she stayed there for one night and returned the next morning.

When she returned, she took about a hundred people with her.

Because most of these people were patients, and some had difficulty walking, she would take some people away in that large helicopter every time she came, except when she needed to go to Nanqi Kingdom.

Because of the march in the freezing cold, some people fell ill with high fevers, and others had their feet blistered and bleeding, causing them to fall behind.

Luo Yushao and his mother and son Li An also returned to Runan City.

Work wouldn't start until the tenth day of the Lunar New Year. With nothing else to do, Nangong Wu held training classes in the evenings and spent the day with Li Zhan, Su Siyan, and several other key personnel looking for places to open cement and steel plant factories.

The army from Zhenyuan should arrive in about a month, and then there will be manpower available.

Work resumed on the tenth day of the lunar new year.

After more than ten days of rest, Nangong Wu's space was automatically replenished twice with steel bars, cement, and various water pipes and other building materials.

Eileen, Li Zhan, and Su Siyan are now engineers, responsible for construction quality and safety, structure, measurement (including verticality control), and guiding on-site process implementation.

They were busy during the day and busy at night, studying blueprints.

Although Eileen was brilliant, she had never built a high-rise building and had no practical experience. Before building the house, they had to design the indoor drainage riser system and then construct the outdoor buried pipe network.

The houses they are about to build will have dedicated bathrooms, equipped with squat toilets or flush toilets, so they can no longer use traditional chamber pots and carry them out to empty them every morning.

"If we do it this way, where will our water source come from?" Nangong Xiao asked, looking at the blueprints.

"The underground well water source here is plentiful, so we'll use it for now. But in case the well water supply runs out, we've also prepared a second option." Nangong Wu pointed to the drawing.

"We will use the water source of the Mao'er River. This is the second dam we built, which is only three miles away. We will use pipes to bring the water over."

"Before that, we need to plan ahead! These projects are a bit complicated." Nangong Xiao's expression was solemn.

The dozen or so people present were all deep in thought, staring at the complex blueprints.

They never imagined that building a city would be so complicated.

In their previous understanding, digging a foundation and building a wall was the same as building a house; once it was built, that was all.

"Making it a little more complicated is to make our lives easier in the future. Let's do it, research and explore as we go!" Nangong Wu said.

"The princess is right."

Everyone nodded.

Imagine how convenient and easy it would be for them to no longer have to go outside to use the toilet, and just flush it with water afterward.

"If everyone in the city uses this water, where will all this sewage go?" Ji Hongfei asked.

"We've already drawn the septic tank!" Eileen drew a circle on the map.

"Domestic sewage first enters this septic tank, where solid-liquid separation is achieved through gravity sedimentation; the solid sludge undergoes anaerobic fermentation and decomposition at the bottom of the tank, while the clear liquid overflows from the outlet..."

"There are only a few septic tanks. What if they get full?" Li Zhan also raised a question.

"We will regularly use vacuum trucks to clean the septic tanks and then compost or incinerate them. The supernatant after treatment will be piped into the original moat first, and then we will build a sewage treatment plant later," Nangong Wu said.

Fortunately, there was a moat, which saved them a lot of trouble.

"The Zhenyuan army will arrive in Runan City at the beginning of next month. We need to build military camps for them according to the original plan."

Nangong Xiao nodded, "Let's put the demolition of the old city wall on hold for now and have someone build the military camp first."

Before we knew it, it was the end of January.

"Princess, Prince, the Zhenyuan army will arrive in Runan City the day after tomorrow." Li Shan walked in with a letter in his hand.
