Everyone's on a time-travel adventure! I'm raising city beasts in a post-apocalyptic world

The Japanese kneeling on the ground were terrified. Some of them, upon seeing Xiao Xuan's current size, pressed their foreheads to the ground, kowtowing repeatedly and chanting something.

Lin Feng looked at Xiao Xuan's current tortoise shell.

"It's big enough; it can accommodate another 10 people."

He communicated with Xiao Xuan telepathically: "Don't stop, build the city walls and houses."

Xiao Xuan manipulated the mountain behind the valley with the power of the earth, stripping away large swathes of rocks and soil, which surged onto his back and began to be shaped according to Lin Feng's requirements.

First, the city wall rose along the edge of the tortoise shell, becoming higher, thicker, and stronger than before, with four towers rising simultaneously at the four corners.

A city gate tower was raised on both the left and right sides, with space reserved for the installation of lifting bridges. Later, Guo Yi would dismantle and modify the original two lifting bridges before reinstalling them.

The newly added area became the new outer city, which Lin Feng divided into 4 areas. After the area in front was opened up, it served as the place where Xiao Xuan stored food and the queen ant's nest. Now that Xiao Xuan has grown so much, it is unknown whether the gold-devouring ants can provide Xiao Xuan with the food he needs.

If the supply can't keep up, the gold-eating ants will probably suffer massive population losses.

In the remaining area, Lin Feng built several rows of circular dormitories and some large houses to house Japanese criminals and slaves, providing them with a working environment that lasted day and night.

Part of it is intended to cope with the upcoming population increase.

In order to repair the Ziwei Star Palace as soon as possible, Lin Feng has decided to use the Thousand-Mile Soul-Chasing Mirror to gather the survivors within a thousand miles, teach them the Great Dao of Cultivation, and help them reach the pinnacle of life.

Just as Lin Feng was thinking about how to use the strange object to summon the survivors, the queen ant kept sending out signals. One of the gold-eating ants would lead a group of gold-eating ants to quickly head to the side of the mountain that Xiao Xuan had just collapsed.

They quickly dug through the rocks and shoveled inside, soon creating deep pits on the mountainside. Lin Feng was also quite curious as to why the queen ant suddenly sent out a large number of gold-eating ants to dig holes in the mountain.

Before long, Lin Feng knew the answer. A gold-eating ant crawled out of the pit carrying a large piece of dark brown ore. There was actually an iron mine hidden in the mountains behind this valley, and it was a vein of black iron that was also present.

Thanks to Xiao Xuan for collapsing most of the mountain, the Queen Ant was able to clearly perceive the iron ore buried inside the mountain. The Queen Ant also told him that this vein was not small, and hundreds of thousands of tons of black iron alone could be extracted, and even more iron ore.

"Haha, this is truly double happiness! The surprise is hidden behind the unexpected."

Lin Feng waved his hand, and two earthen mounds rose up to the left and right of Xiao Xuan. The Gold-Eating Ants lined up in neat rows and carried pieces of ore along the mounds to the designated locations.

Guo Yi practically ran over. He had seen the gold-devouring ants carrying up the ore from afar. He jogged up to Lin Feng, panting, "Lin Feng, you've found some iron ore?"

Lin Feng heard Guo Yi's voice, which saved him the trouble of going to find him alone.

"Yes, it's inside the mountain. Luckily, Xiao Xuan just happened to collapse half of the mountain, which was detected by the queen ant. The iron ore is accompanied by black iron, and the reserves are not small."

Upon hearing that the reserves were substantial, Guo Yi beamed with joy: "Hehe, then you can give me a larger share this time, right? I need a batch of black iron ore to research and develop new level 4 tanks. I've discovered that the original tanks are no longer sufficient to deal with the more powerful and mutated creatures. The millipede swarm we encountered this time was completely ineffective with the tanks I modified before."

"I know you're anxious, but don't rush," Lin Feng interrupted him. "Put the chariots aside for now. There are two urgent matters to attend to, so please proceed in order."

"you say……"

"First, go and inform Luo Xiaoxiao and Mi Xue to rush out a batch of black iron grade ore picks, at least 3, the sooner the better. I plan to have those 3 Ghost Masters mine. They all have ghosts parasitizing their bodies, so they are strong and can work continuously without rest."

"The ore is only ours once it's mined out. What if there are some unknown mutated creatures or strange things in this jungle? We won't be able to withstand them and we'll have to run away, right?"

Guo Yi nodded.

"Secondly, we need to dismantle the original two lifting bridges, modify them, and reinstall them under the outer city gate tower. The current ones are too narrow, so we need to make transportation easier."

"We'll talk about the chariots you mentioned later. In the next few days, I'll be teaching you a set of cultivation techniques; those are the real gems."

Guo Yi asked, "Cultivation techniques? You've come up with something for cultivating immortality?"

Lin Feng didn't answer directly, keeping him in suspense, and handed him a black plaque: "You'll find out in a few days. This is made from the shell shed by the queen ant. I'll have you gather some Gold-Eating Ants to help. Go."

Lin Fengyue remained silent, which only fueled Guo Yiyue's curiosity. However, seeing that he couldn't get any information out of him, he had no choice but to go and get back to work.

After seeing Guo Yi off, Lin Feng first went to Zi Ling'er to ask for two inheritance jade slips, and then found Zhao Gao.

"Old Zhao, come here for a second!"

"Your Majesty, what are your orders?"

"Go find Zhuoma and ask her to mobilize the guards to help you take these ordinary Japanese survivors to the outer city and settle them in. Then let them practice the Qi-gathering technique and select some of the obedient ones to assist you in managing them."

Lin Feng handed him a jade slip containing a causal restriction. This restriction would ensure that the cultivation results of anyone who cultivated through this jade slip would be transmitted 100% back to the Ziwei Star Palace. Even if they later learned without using the jade slip and privately passed on their knowledge, they would still be affected by the causal restriction, and apart from becoming stronger, they would not retain any magical power.

"Old Zhao, this jade slip has many functions. It contains almost all the Qi gathering methods of all attributes, as well as a minor spell—the Universal Knowledge Spell. It can understand the meaning of everyone's speech, eliminating the problem of communication due to language barriers. Everyone who has cultivated this spell has a corresponding number. You can check each person's number through the jade slip and manage them in groups. Most importantly, you can check each person's cultivation progress and results to ensure that no one is slacking off."

Lin Feng taught Zhao Gao how to use his mental power to control the jade slip, project information, and perform other operations.

Zhao Gao wrote them down one by one.

"Your Majesty, rest assured, I will definitely manage these Japanese people well for you and will not delay your affairs."

"Yes, I trust you to handle things. We've also set up several manned power plants in the outer city, operating 24/7. Xuanfeng City is large, and the power shortage is significant." Lin Feng said, handing over another jade slip. This one was a different color, a pale gold, specially prepared for the Great Xia people in the inner city. Only 99% would be taken, leaving 1% for them.
