What is this crystal?

It looks like a psionic core, but it's incomplete, more like fragments.

Qin Che waved his hand, and a large number of flying blades spun out, grazing past the equipment.

However, the equipment and petri dishes only made clanging and banging sounds and produced a few sparks, but they did not damage them.

"So hard."

Qin Che frowned; these materials were no ordinary matter.

It was able to withstand the Master's attack.

Qin Che stepped forward, followed by a chorus of footsteps.

A dense mass of soldiers was converging on the dungeon.

They appeared behind Qin Che, fully armed and carrying guns.

"Halt! This is a forbidden area of ​​Yonghuan Fortress; outsiders are not allowed to enter!"

"You are guests, yet you have trespassed into our forbidden area without permission. What do you want?"

"Commander Xu will be here shortly, please come with us!"

"Otherwise, don't blame us for shooting!"

Qin Che, with his back to them, smiled and pointed to the crystal in the petri dish, asking, "What's this?"

The soldiers were furious at Qin Che's attitude, and the next second, they opened fire!

Bullets poured out, and Qin Che pulled the trigger, the gun barrel spitting fire and bullets flying everywhere.

Gunshots rang out incessantly.

Qin Che suddenly disappeared from everyone's sight.

The next second, countless flying blades emerged from the darkness, moving even faster and making them impossible to defend against!

Puff puff puff—

Wherever the flying blades passed, they pierced through countless bodies, and large numbers of soldiers fell to the ground.

Screams echoed one after another.

Qin Che darted through the crowd, punching, kicking, and elbowing his enemies one by one.

He didn't expend much effort.

Soon, sounds of fighting and gunfire came from above the spiral staircase.

Qin Che also sensed Li Xin's particle light and the battle here, so he rushed over immediately.

The troops below were quickly dealt with.

The same thing happened above; the sound gradually faded away.

As the last person fell to the ground, the dungeon was covered in blood.

The prisoners on both sides stared in astonishment at this scene, pressing their faces against the glass windows as they watched Qin Che sheathe his sword, utterly shocked.

"An extraordinary individual!"

"Superhumans have come to our rescue!"

A slave shouted loudly.

However, Qin Che couldn't hear them talking because the glass windows on both sides were soundproof.

He glanced at the slaves, but felt nothing.

They thought they had found hope, but in reality, Qin Che's only interest was in this crystal.

At this moment, Li Xin materialized out of thin air beside Qin Che and asked him, "What is this thing?"

Qin Che glanced at him: "Have the people above been dealt with?"

Li Xin nodded. "I didn't kill him. I spared Xu Yisong's life."

"That's for the best. It doesn't matter if some soldiers die, but Xu Yisong is the commander-in-chief here. If he dies, it will cause some trouble."

Qin Che continued looking at the crystal shard: "Do you have a way to open this petri dish?"

Li Xin pinched his nose, then realized: "Using the lives of prisoners to feed this crystal? Is that how it is?"

"Yes, crystals need to absorb carbon-based life forms to generate energy. This device is like a black box; it can't be opened, and the material is so hard that even I can't break it."

"I'll give it a try."

Li Xin reached out, his palm facing the petri dish and the cluster of equipment. Countless points of light emanated from the dish and disappeared into the cluster of equipment.

"That's strange. As soon as my psionic energy entered, I lost contact and had no control. It seems I can't do it either."

Qin Che frowned and said, "This is ancient technology."

How can you be so sure?

"Current technology can't do it. Only ancient technology could create such a black box assembly. And don't you think this crystal, although it's just a fragment, is very similar to your psionic core?"

Li Xin nodded: "It does look very similar."

"Grab someone and ask them how to open this."

Li Xin nodded, floated away again, and returned a short while later, grabbing Xu Yisong.

Xu Yisong was beaten black and blue, drowsy, his face covered in injuries, looking like he was on the verge of death.

Li Xin patted his face and asked, "Hey, how do I open this?"

Xu Yisong struggled to lift his head, glanced ahead, and sighed: "When we discovered it, it was just like this; we had no way to control it."

"So how do you extract its energy?"

Xu Yisong said weakly, "This underground area is a natural computer. Its energy is connected to the earth's veins, so we can use electricity without even laying circuits."

Qin Che frowned.

If what he says is true, then this ancient technology is quite advanced, and it is already very close to the envisioned scenario of a future world with nuclear fusion energy.

Electricity is everywhere; there's no need for electrical wiring. It exists in the air.

People's electronic devices are always fully charged without needing to be charged.

Cars can fly, maximizing energy efficiency, and weapons, food, and various factories can also be produced at maximum efficiency.

Yonghuanbao is such a small place.

Qin Che remembered that his residence still used electric lights.

"Those are just illusions. There are actually no power generation facilities at all. This underground space is the only source of energy," Xu Yisong explained.

Qin Che suddenly realized.

"Hey, are you taking this with you?" Li Xin asked him.

"It's impossible to open it, how are you going to take it away? What materials are these equipment clusters made of... biological products?"

"It doesn't seem like it. The ability to isolate our psionic energy must be part of psionic technology," Li Xin analyzed.
