He raised his head, looked at the two of them, and said seriously: "The body has reached an extraordinary level, but the spirit is far from the strength of an extraordinary person. Do you really think you can be safe like this?"

"Spiritual level...?" Luo Yunfan replied feebly, "You really gave me a difficult problem. This is an area that our science cannot touch yet."

"The so-called awakener means sublimating one's own spiritual level when defeating the endless nightmare, so that one's spirit can be strong enough to contact the origin of the other side... That is the starting point of all extraordinary powers." Xiao Yao analyzed seriously, "Law enforcement

Those nightmares of those who are not strong enough are the backlash caused by contact with the origin of the other side."

"Anyway, I can't fully understand these mysterious things, so don't expect that nerd over there," Su Yunyun said unceremoniously, "Tell me something real. Do you have any solution?"

"That...this..." Xiao Yao was a little unsure about the title. Originally, Su Yunyun was too petite, but from her previous words, Xiao Yao knew that this person was at least one or two years older than him, "Miss?"

Do we have any misunderstandings? How can you tell and how can I help you?"

"Because Sister Qian'er," Su Yunyun replied, "Although she has only met you once, she tried to use her mental power to detect your spiritual world during that meeting... and the result was beyond her imagination."

That... brown fox? It's really cunning... Xiao Yao held his forehead, even with Elizabeth's reminder, he still couldn't guard against it.

"I'm not sure what Sister Qian'er saw in your spiritual world. Anyway, it was some kind of existence that even she, as an exception, was a little afraid of. After she knew about my situation in Jiu'an, she told me

:If there's anyone in the world who's best at dealing with nightmares, it's you."

"I finally understand the cause and effect..." Xiao Yao sighed. Undoubtedly, Su Qian'er sensed the terrifying nightmare in her spiritual world, and then Su Yunyun subconsciously believed that she had unilaterally suppressed the nightmare and became extraordinary.

, thereby overestimating one's own strength.

But...if it hadn't been for Yiyi at that time, Xiao Yao would have been so cold that the grass on the grave would have grown three feet tall.

In the current situation, he couldn't move out of Yiyi under any circumstances. After all, Su Yunyun was present. Although she said that the Su family didn't care about her, she seemed to have a good relationship with Su Qian'er, the fox. Although they only met once, Xiao Yao

A man's consciousness tells him to stay as far away from her as possible.

Anyway, before you think of a new solution...change the topic.

"Speaking of which... I still have a doubt."

"What?" Luo Yunfan asked.

"Why did you engage in this dangerous research in the first place? As a mortal who didn't understand the supernatural realm at all, what motivated you to come into contact with the world of extraordinary beings? It was initially a nightmare for you as your experimental subject. When you came into contact with Su Yunyun

Where did it come from before?"

Luo Yunfan was silent beyond Xiao Yao's expectation. For a long time, as if he had made up his mind, he said in a hoarse voice: "Xiao Yao, what I will say next may subvert your understanding——

Do you believe in the existence of repetitive civilization?"

"Repeat civilization?" Xiao Yao was stunned for a moment. It's not that he didn't know the meaning of this word, but it was just that this word, which was an unsolved mystery even on Earth, appeared so suddenly in the world of Koro!

Repeating civilization, in Xiao Yao's previous life, is a conjecture that cannot be proven: on earth

During the 5 billion years of evolution, life on the earth has experienced countless mass extinctions, life and death, over and over again. As a result, many advanced civilized societies have appeared on the earth, and the Mayan legend is one of them.

Now it seems that Kolo in this life may have similar legends.

"There are many unsolved mysteries in the world of Kolo. The shoe prints on trilobites, the intertwined footprints of humans and dinosaurs, the metal vase 110,000 years ago, the iron pot 300 million years ago, the 2.8 billion

Year-old metal balls, prehistoric telescope stone carvings, ancient airplane models, nuclear reactors two billion years ago, human footprints in the Cretaceous strata, human footprints in the Cretaceous strata..." Luo Yunfan continued to give examples.

Xiao Yao nodded: "I have also heard that these are Ke Luo's famous unsolved mysteries... But what does these have to do with what we are discussing?"

Luo Yunfan showed a mysterious smile: "Do you still remember how I explained my research to you at the beginning? I only used one sentence to describe... a technology that does not belong to this era. That sentence was not a joke."

Xiao Yao's eyes widened. He understood what Luo Yunfan meant in an instant. Another piece of the puzzle about the nightmare experiment emerged. No wonder Luo Yunfan has such superb technology, even beyond the level mastered by the three major families. No wonder

This laboratory is as advanced as a science fiction movie...

"Could it be that...you used other civilizations...before primates appeared in this world...the technologies of other intelligent creatures?" Xiao Yao looked at Luo Yunfan in disbelief. He thought that the things in Jiu'an City were his.

He was looking for part of the truth, but unexpectedly it involved something he had never thought of... Or is this part of the truth about the world?

"Well, to be precise, it was the previous owner of this laboratory." Luo Yunfan shook his head and walked towards the depths of the laboratory, "Follow me, and I will show you... my original experimental place.

.”

They kept walking towards the depths of the laboratory. As they went deeper, the experimental layout around them became more and more outdated and more contemporary. It was like they were looking back in time, approaching countless years ago little by little.

The place where it all began. The road began to slope downwards. When they passed the end of a long series of laboratories, there was a wall with a metallic luster in front of them.

Xiao Yao stretched out his hand and gently brushed the wall. A rough texture came from his fingertips. The surface of the solid wall was uneven. This was not an ordinary wall, but was made directly from molten steel!

"Yes, just as you thought," Luo Yunfan nodded, "This laboratory was built on the site of other people's laboratories many years ago. I don't know what happened to those people during their experiments.

, they left in a hurry in the end and sealed the deep underground laboratory with molten steel, leaving many precious research materials and experimental equipment in the laboratory above."

Unexpectedly, there is such a story here... Xiao Yao can imagine that when the red molten steel poured from top to bottom into the narrow corridor, blocking the only way out of the unknown underground, completely turning the deeper darkness forever

Blocked in the deepest realm.

At that time...could someone be running wildly in this long corridor, with molten steel about to pour in front of them, and pursuers in the darkness behind them. They shouted, wait, wait, let me out, but they were still beaten.

The ruthless man pressed the switch that poured molten steel, and the fiery hell locked everything underground.

"They...about when?" Xiao Yao asked.

"About a hundred years ago? The exact time cannot be determined." Luo Yunfan thought while dragging his chin.

It was a hundred years ago again...a really weird time period

, I always feel that many things I have experienced started a hundred years ago... Xiao Yao frowned.

"In the experimental data they left behind, it was clearly stated that the technology they used was the legacy of the previous civilization, and the tombstone of that civilization was buried in the deepest part of Jiu'an City - unfortunately, probably due to the earthquake, the path leading to that civilization

The underground passage of the civilization ruins is blocked, and I have no way to clear it yet. Although I cannot touch the tombstones of that civilization, there are many heritages of that civilization blocked behind this wall."

"So what about here?" Xiao Yao pointed at the poured wall, "Have you opened up the back?"

"It was too difficult to break through this wall. I didn't have that much money at the time," Luo Yunfan shook his head, "However, it was relatively easy to break through the rock layer next to it. It's just that... we were too young and didn't realize it at the time.

They sealed this place not to bury the knowledge inside, but to protect the people outside."

Looking in the direction indicated by Luo Yunfan, Xiao Yao saw a narrow passage on the side of the metal wall. The passage was uneven and covered with plant roots, gravel, and soil... Every few meters, there were lines on the side of the passage.

There was only a small lighting lamp inserted, but the faint light seemed unable to fight against the endless darkness. It could not spread for a few steps before being swallowed up by the darkness.

This place... really doesn't look very auspicious...

"We were a whole scientific research team at that time. We even hired a professional team to dig this channel. When everything started, there were more than a hundred people here." Luo Yunfan's voice was a little low, "But when

When we dug out the final passage... To paraphrase an old friend of mine, the world over there is a dark scroll belonging to the age of myth, a demonic curse that mortals should not be able to glimpse!"

"Sorry, if I'm not mistaken, there should be...a lot of nightmares over there, sealed by molten steel in a small underground space for more than a hundred years. They must be almost crazy, and you are just a group of mortals..."

"At that time..." Luo Yunfan shook his head, as if he was unwilling to recall the memory that was too terrifying for him. "When everything settled, there were only a dozen of us left. If it hadn't been for that time,

The captain had an ominous premonition. If he insisted on letting us carry weapons, we might really be wiped out.

"It's no wonder...so the original test subjects of the nightmare experiment were those nightmare corpses that were exchanged for their lives by mortals?"

"Actually, several nightmares had their limbs chopped off and used them for my living research... However, I still underestimated their vitality at the time, and one nightmare with only its torso escaped... Fortunately, I was able to

Get to know Yunyun."

Su Yunyun, who was walking at the front and leading the way, hummed softly and her cat ears twitched to show that she was listening.

"Your companion..."

"We buried the dead, and the living chose to continue our research - this was an opportunity that our companions had sacrificed their lives for. Do you remember the Berserker? He was the captain of the professional excavation team. And the executioner... was

The only daughter of the captain of the research team, after her father died, she had no one else to rely on but us."

"I repeat again, you are really a group of guys worthy of respect." Xiao Yao said seriously.

"Thank you." Luo Yunfan said briefly, lowered his head and walked to calm down his mood.
