People in this world seem to like living underground.

When Su Ziyu followed Jane to the main base of the rebels, he couldn't help but sigh that the natives of this world really maxed out their digging skills.

The main base of the rebels was called Tieshan, where there was originally a rich iron ore. They dug hundreds of meters underground and built their base camp inside. The entire underground base covers a large area, close to a town, with tens of thousands of people living there, and has complete living facilities, including planting areas, residential areas, medical areas, weapons depots, etc.

The man named Bobby took Su Ziyu to a separate bedroom and said, "You can rest here for a while. I will take you to the restaurant in an hour."

Su Ziyu nodded slightly, then pointed to a light green iron lump not far away and asked, "What is that?"

"Oh? That! It's a nutrient machine." Bobby glanced at the machine covered with ash in the corner and said, "It produces nutrient paste from organic matter. The inlet is on the other side."

“It’s been a long time since I’ve used it.”

"Believe me, you won't like the taste of that stuff."

"When the main base was first built, the planting area had not yet been established, so we relied on this for a while."

A machine that synthesizes food?

Su Ziyu smiled, pushed the door and walked into the room.

The furnishings in the room are quite simple: a bed, a light bulb, a table, a simple cabinet, and a small statue of a mechanical clock.

"This thing?" Su Ziyu's expression was slightly surprised, and he reached out and touched the small statue in front of him.

It is made of metal, iron-gray in color, and very precise. It looks like a real clock, but it also seems like some kind of ritual item. The most surprising thing is that it has been blessed by someone, and there is a very faint layer of spiritual light on it, which seems to have a very faint effect of soothing the mind when touched.

"Who did it?" Su Ziyu murmured.

The aura on this thing cannot be acquired by ordinary people. It must be a priest or other special professions.

This is fantastical.

Su Ziyu walked out, and seeing that there was no one outside, he casually opened the next room with his fingertips. The furnishings were the same, all quite simple, except that there was also a small metal statue, but it was not a clock, but a complex lever sphere.

"Do they rely on this thing to calm their minds?" Su Ziyu said to himself.

In this world filled with whispers of the soul, normal people will be polluted to some extent.

To put it in a more fashionable way, the SAN (sanity) value decreases.

This small statue placed in the room can sober people up and restore their sanity to a certain extent.

After getting to know this world, Su Ziyu also knew what those savages living outside were like. Some of them were ancient indigenous people, and some were real savages.

Most of these people are born with dull minds and insensitive hearts, so it doesn’t matter if they live outside.

Most of them may never hear the whispers of their souls in their entire lives.

Taking normal people as a benchmark, the mind sensitivity of ordinary people is 1, and they can occasionally hear the whispers of the mind. The mind sensitivity of people who have a relationship with the empire is 1-2, and they are affected by the whispers of the mind for a long time, including the rebels of the empire. The mind sensitivity of the nobles of the empire is 2+, and they have been tortured by the whispers of the mind since birth.

As for those savages who can move around normally outside, their mental sensitivity is naturally 0-0.5.

Among them are wild men who are completely mentally deaf.

This also means that they will never be able to sense psychic energy in their lifetime, and they have absolutely no talent for practicing to gain psychic energy. This kind of people were abandoned by the empire many years ago. At that time, only humans with talent could join the empire, and their tribes would be accepted by the empire to teach advanced knowledge. Humans without talent would only be abandoned, but now the lack of psychic talent has become a kind of protection for them.

Su Ziyu returned to the room, took out the Holy Blood Sword, and ordered: "System."

"Breaking the genetic lock."

In an instant, a huge amount of data stream emerged in Su Ziyu's mind. He was slightly dazed for a moment, and then slowly returned to normal.

As expected, breaking the genetic lock is no small burden.

Su Ziyu temporarily blocked the stream of data pouring out of his mind and began to sort out his other spoils.

The common lightsabers of the Imperial Knights are all similar, but after Su Ziyu simply disassembled them, he found that they were actually filled with batteries. They were smaller than the nuclear fusion batteries in the wasteland plane and had a higher output power, but they were still far inferior to the unknown energy crystals in the Holy Blood Light Sword. The front end of the hilt was a device that confined plasma and shaped it into the shape of a sword. The technology was beyond my understanding, so I didn't know the principle for the time being.

Each plane has its own characteristics.

In the Dark Soul plane, Su Ziyu can easily obtain soul energy, and in this plane, his biggest gain should be the various black technologies.

"I wonder if we can build a spaceship?" Su Ziyu said to himself.

If he could get a spaceship, it would be of great help to him in the future.

An hour later.

There were soft footsteps outside the door, followed by Jane's voice: "Su? Are you there?"

Su Ziyu pushed the door open and asked, "Are you done with your work?"

"Yeah." Jane nodded and said, "The things have been handed in. Let's go. I'll take you to the restaurant to eat something."

The rebels' cafeteria was quite luxurious.

The area here is more than one thousand square meters, with dining tables placed in the center. There are many kinds of food, but the main ingredients are potatoes, potatoes, and potatoes. The side dishes of potatoes include meat, fish, poultry, vegetables, etc.

Su Ziyu was obviously not very interested in this restaurant that served potatoes as food.

"Do you want to go over there and play?" Seeing that Su Ziyu had barely eaten anything, Jian couldn't help but introduce enthusiastically, "There's an immersive virtual game cabin over there."

“The games in it are quite fun.”

"If we are too tense and tired, we will apply to go in and relax."

Game cabin?

Is there such a good thing?

Su Ziyu nodded in surprise and said, "Take me to see it."

This should be the entertainment room.

But there were no people. There were some TVs, computers, game consoles, etc. outside. The time span was very large, with a difference of several decades. However, the entertainment hall at the innermost part was extremely luxuriously decorated. The access control was actually a retina scan. With a beeping sound, Jane opened one of the special closed rooms.

——"Shining technology! Shocking!"

As soon as Su Ziyu stepped into the room, he was shocked by the huge silver-white metal cabin in front of him.

"This is a good thing that the rebels found from an interstellar merchant ship." Jane looked at Su Ziyu's surprised expression and smiled, "It is said to come from a distant shining technological civilization."

“Their medicines are pretty powerful, too.”

"Want to try it?"

Su Ziyu nodded and said, "Give it a try. I'm very interested."
