The only valuable piece of information is that there are still dozens of old-world humans lying in the shelter underground in the pit area. They are still alive... We can dig them out and ask them about what happened back then if we have the chance in the future.

Most importantly, they are all elites from various fields, and if they can be put to use, the technology of the old world can be completely revived.

The old-world technologies currently possessed by the Psionic Research Institute are all fragmented and have some research value, but replicating them is extremely difficult, or even impossible.

Despite years of exploration in Lingbi City, the only weapons technology developed so far is something like incendiary guns and chainsaws, which are still at the beginner level.

True high technology cannot be replicated.

In that case, the 'full version' of old-world technology appearing in the simulator is indeed a huge cheat code.

Perhaps the synthetic starch technology underground in that Shelter No. 1 was incomplete, but because Qin Che chose it in his simulation, the system provided him with the complete version, allowing him to completely replicate it; otherwise, it would have been just wishful thinking.

That makes sense. Technology from hundreds of years ago has long been buried. Even if it still exists, it cannot be put back into operation because there is no technology to repair it.

Even if you copy a lithography machine, the resulting technology and the chips produced will be vastly different. How much more so with future technologies like this, where the variables are unpredictable.

This is equivalent to asking primitive people to build automatic rifles. They wouldn't even be able to repair them, let alone build them. Even if they copied them, they would only produce something that was neither fish nor fowl, and they wouldn't be able to produce or understand the parts.

Such a leap is too unrealistic.

The next second, an ordinary-looking reagent appeared in Qin Che's hand. The reagent tube contained a black fluid that emitted a starlight-like glow, and some bright red color could also be seen in it.

Strictly speaking, this is the blood from the girl who is immune to the Black Disaster.

Because she is immune to the Black Catastrophe, but at the same time, the Black Catastrophe exists in her body, her blood is no longer like that of an ordinary person, but it is not entirely blood either, because it is something produced by the laboratory's technology.

After Qin Che mustered up his courage and injected himself, he felt nothing.

He immersed his spirit in the world of the Black Tide.

In an instant, the entire black tide became much clearer in his eyes. Qin Che had never experienced such a level of sharpness even during his previous cultivation. It was a different feeling altogether.

Perhaps it's because the version of myself in the simulator looks too old, and I mistakenly believe I've regained my sharpness, but that's not the case at all...

Even he, now young, can clearly feel this change.

The Black Tide seemed to have improved its compatibility with him, and this world became much more familiar to Qin Che.

Is it because of the Black Catastrophe serum?

Qin Che frowned and began to travel around the Black Tide World. He first wandered around the coordinate stone, and then gradually went deeper into it. The deeper into the world, the more viscous it became. As Qin Che wandered, he pondered the operating logic of the Black Tide World.

There is also an element table here.

However, with current technology, it is not possible to conduct research on the Black Tide world.

Such technological capabilities are even less available in the desert.

After clearing away the starlight and cultivating briefly, Qin Che returned safely without encountering any black calamity. At this moment, his spiritual energy limit had increased almost imperceptibly. Previously, he had not immersed himself in the black tide to cultivate because he was worried about being infected by the black calamity, but now he could continue without restraint.

At that moment, someone knocked on the door:

"Lord Qin, your attendants have arrived."

"Okay, let her in."

He knew in advance that Xiao Shitou was coming to see him, and Qin Che showed a warm smile when he saw Xiao Shitou, whom he hadn't seen for almost a month.

“Master!” Little Stone’s eyes sparkled. During her training in the military camp, she thought about Qin Che every day.

"Hmm, not bad, not bad, you've gotten much stronger. Looks like you're doing quite well in the military camp." Qin Che nodded with a smile, patted her head, and gave her a fatherly smile.

Little Stone chuckled, "Master, I've been working really hard, training every single day!"

"That's good. I heard you're Chen Da's bodyguard now?"

"Yes, Commander Chen needs my help, after all, he's already a psionicist."

Although Qin Che had been informed of Little Stone's characteristics via telegram long ago, he first learned about them in the simulator.

"Tell me about your characteristics in detail."

"Yes." Little Stone nodded: "It's called Super Intuition. You can use it once a day without any burden, because if you use it too often, I'll get a headache. The doctor said that it would put an irreversible burden on the brain. Sister Peach and Commander Chen both ordered me not to use it more than once."

"Hmm, anything else?"

"My premonitions are always pretty accurate, with only slight errors. For example, I know you'll pick up the teacup with your left hand in the next second, sir..."

Before he finished speaking, Qin Che had already picked up the teacup with his right hand.

He was slightly taken aback.
