Qin Feng didn't have the Qi Sea of Waste Yan Mountain, because there was no need.

His current strength, below the second-level secret cultivation, can almost be said to be invincible.

No first-level secret cultivator had such a wide spiritual sea as his, and there was such a thick and viscous spiritual mist as him.

And his greater hard power is the various first-level secret skills obtained from the New World, as well as the offensive and defensive combinations between them.

On Earth, many first-level secret cultivators could only understand four or five kinds of secret techniques at most, while Qin Feng knew dozens of them, and they had a variety of combinations.

From this point alone, he had left the earth's first-level secret cultivators far behind.

Qin Feng and Yan Shan came to the entrance of the dungeon again, and found that it was heavily guarded by Yan Shan.

It stands to reason that Ning Tiancheng is dead, so there is no need to guard it like this.

The two went deep into the dungeon and came to the innermost metal cell.

Ning Tiancheng's body was still there, and his face still maintained a twisted pain and horror.

Yan Shan really wanted to know how Qin Feng killed Ning Tiancheng, because Ning Tiancheng obviously didn't die from external injuries, and he didn't have any wounds on his body.

However, he thought about it and still didn't dare to ask.

The world is unpredictable, not long ago, although Yan Shan admired Qin Feng very much, he was still in the mentality of looking down from a high place.

But now, facing Qin Feng, he actually had to think about it in his heart a few times when he said a few words.

At this time, Yan Shan used a special key to remove the chains, throwing Ning Tiancheng's body aside, and his gaze was fixed on the stone platform below, on which there were symbols composed of spirit patterns.

"My request is to let Ning Tiancheng inject his spiritual power into it, his spiritual sea is about to be abolished, and it is impossible for him to have such a place to store spiritual power, so we happily reached a deal. Yan Shan said with a smile.

Qin Feng didn't speak, he knew that there was still something to follow.

Yan Shan stretched out his hand and stroked these spirit patterns on the stone platform, looking at his expression as if he was a little hesitant, and seemed to be weighing something.

In the middle of the night, he took out a diamond-shaped key and inserted it into a hole in the stone platform.

There were a few laser-like points of light on the key that flickered, and in an instant, the stone platform began to flip.

Qin Feng took a step back, his eyes were guarded, and he held the "Frost and Snow" tightly in his hand.

It's just that when the stone platform was flipped over, rows of buttons were revealed.

Soon, the buttons lit up as well.

Qin Feng looked surprised, this should be equipment from ancient times, such as a computer or something.

Yan Shan pressed a few buttons on it.

Suddenly, the innermost metal wall began to shake and sank into the ground.

Behind the wall, there is a glass-like thing, by the way, this thing should be called glass in ancient times.

It was pitch black inside, but Qin Feng's eyes could see in the dark.

There are many tables and chairs, as well as various large machines.

However, these were all destroyed and almost turned into parts. Moreover, the walls inside were all large and large pieces of collapse, revealing the thick metal layer on top.

In addition to this, there are traces of black blood that have been coagulated for an unknown number of years, as well as the broken bones of humans.

Qin Feng involuntarily walked in front of the glass curtain and glanced inside.

At this time, he found that there were beast paw prints everywhere, even the thick layer of alloy.

He was terrified in his heart, this kind of alloy left over from ancient times was extremely strong, and he could only leave a shallow mark on it when he hit it with all his strength, and if he wiped it with his hand, it was almost invisible.

And the beasts that can leave paw prints on them must at least be second-level fierce beasts, or even third-level fierce beasts.

At this moment, a black shadow suddenly rushed towards Qin Feng in front of the glass.

Qin Feng's hair exploded all over his body, and he dodged with a backward flip.

"Bang"

There was a dull sound, and the black shadow slammed into the glass and fell, and the two eyes glowing green flickered in the darkness like two ghost fires.

Can't get out?

Qin Feng breathed a sigh of relief, this was a fierce beast covered in black hair, which looked like a dog and a wolf.

Definitely a ferocious beast!

And at this moment, another fierce beast rushed over, densely packed, instantly filling Qin Feng's sight, there were hundreds.

At this time, Yan Shan pressed the button, and the metal wall that sank into the ground rose, covering everything up.

Qin Feng was still a little shocked in his heart, what was in this, and what happened?

"This is an ancient laboratory, and this stone platform is a console, and the spiritual power stored in the spirit pattern on it is the backup energy source to maintain the operation of this console, because once the supply of spirit stones is cut off, it can only be maintained by this backup energy, but it seems that something has happened, and the spiritual power stored in the spirit pattern has disappeared. "Yanshan Road.

"I absorbed it. "Qin Feng said.

Yan Shan nodded, he had already guessed.

"What the hell is going on?" Qin Feng asked, really a little curious.

"Let's go out and talk about it. "Yanshan Road.

The two of them came out of the dungeon and came to the mound above the dungeon.

"Hundreds of years ago, the earth was cataclysmic, and the strong magnetic storm destroyed the scientific and technological civilization at that time, and the fierce beasts that emerged from all over the world wreaked havoc on the planet. But it wasn't enough, in order to explore the reasons for dealing with fierce beasts, the earth established many laboratories at that time, began to study fierce beasts, and even expected to use fierce beasts to deal with fierce beasts, but not only did it not succeed, but instead gave birth to stronger and more intelligent fierce beasts. Yan Shan sighed.

"And then?" Qin Feng asked.

"I don't know the specifics, I only know that the nine powerhouses in the world broke through the space and entered the new world with some people, and we were left on the earth, but fortunately, those high-level intelligent beasts that can turn over the river and the sea don't know why they have disappeared, and the human beings who remain on the earth can open up a living space surrounded by fierce beasts. "Yanshan Road.

Qin Feng nodded, he knew some of this.

"Then what do you have to do with this laboratory?" Qin Feng asked again.

"In order to protect themselves, there were many organizations left behind on the earth, and the Salvation Society was one of them, with the mission of saving the world, it was one of the largest organizations, and this laboratory has been supervised by the Salvation Society. But then a lot of things happened, the Salvation Society fell in pieces, from light to dark, and now in this area of the wasteland, my stronghold is the only stronghold of the Salvation Society. Yan Shan said without sorrow.

"So, you are unscrupulous to make money in order to maintain the basic operation of this laboratory?" Qin Feng asked.

"That's right, once the laboratory stops operating, the genetic beasts that have evolved for hundreds of years inside come out, and the dozen or so cities in the entire wasteland will not be able to be saved. "Yanshan Road.

Qin Feng took out his pipe and lit it, took a puff, and said, "It is undeniable that when you say this, you suddenly look very great, but I have a question, since you don't have the strength to protect this laboratory, why don't you let a stronger force take over, such as Moonlight City, which is about to become a third-level city, or a higher-level second-level city?"

"Hehehe, Qin Feng, you underestimated the inferior nature of human beings, the fierce beasts in this laboratory will be a disaster for most people, but it is also wealth for a small number of people, this is a genetic beast that has evolved for hundreds of years, if it can be controlled, or directly slaughtered to obtain materials, how much wealth can be exchanged for it?" Yan Shan sneered.

Qin Feng nodded with a deep groan, indeed, for some ambitious forces, they would definitely not be willing to guard this laboratory.

Besides, who would be willing to be such a fool except for a person of faith like Yan Shan, who would be willing to be such a fool if he invested wealth in it indefinitely to maintain its operation.

At this moment, Yan Shan suddenly got up, walked in front of Qin Feng, and knelt down directly.
