And there is weak air convection.

"It's amazing. I didn't expect that there is such a vast space dozens of kilometers below the surface of the planet." Li Yunpeng sighed.

Li Yunpeng observed for a while, leading people to explore the depths.

The underground space is barren and empty, but there are also some special plants living there. Where there are luxuriant plants, there is still water flowing through.

Li Yunpeng explored along the current. After walking for more than ten kilometers, the vegetation began to grow.

"Ok?"

With a move, Li Yunpeng came to the side of a huge boulder.

"Human bones?"

Moreover, it seemed that it didn't feel like a long time ago, and the bones were scattered and discarded.

Beside the bones, there are still traces of burning.

"Think of humans as food?"

Li Yunpeng frowned, with frost on his face.

"go!"

Under his leadership, everyone continued to explore in depth, and after walking for a few kilometers, they found a nest community in which many creatures lived.

Li Yunpeng took a closer look and saw this group of creatures, which looked very much like upright lizards. The single body was four or five meters tall and had a cruel image.

Before he waited for a long time to observe, suddenly saw the entire ethnic group on the opposite side stop, the nose twitched, and then quickly determined their direction.

"Fuck, so keen sense of smell?"

"Boom..."

This group of lizardmen ran together, and the earth was trembling.

"Mou——!"

This group of orcs made a dull cry as they ran, and soon, their similar races appeared in all directions.

Li Yunpeng felt like he had fallen into a hornet's nest.

"withdraw!"

Looking at the momentum, this group of things is not so easy to mess with.

Li Yunpeng and others ran wildly along the way.

Unfortunately, a small group of lizardmen also appeared on the way back.

"Chang!"

Li Yunpeng's speed did not decrease and he drew his sword to face each other.

Several senior evolutionaries of the guards drew their swords at the same time, and their faces were fierce. No matter what kind of danger they faced, as long as the commander was there, they would have infinite confidence.

"kill--!"

Li Yunpeng let out a roar, and instantly met with the lizardman.

As soon as he fought, he felt that the strength of this group of lizardmen was not simple.

"Quickly, get out as soon as possible. It will be troublesome to be surrounded." Li Yunpeng shouted.

Even these ordinary lizardmen, he is very hard to kill. Not only is this group of things thick and thick, with sharp claws, but also has agility and tenacious vitality. They cut off half of their shoulders. They all have a glance at the okay person. It is hard to imagine how far away. Thousands of people surrounded the consequences.

"Commander, you go first." Li Qi kicked a lizard man who leaped forward.

"Stop talking nonsense, kill!"

Li Yunpeng fought hard, he could not count how many lizardmen killed by the knife, and finally rushed to the entrance of the dungeon before the army came.

Two minutes after they went up, the passage below was blocked by the lizardmen that came up like a tide.

Li Yunpeng and others climbed up quickly like apes, leaving the lizardman far behind.

The lizardman was heavy, but still did not give up, until the **** gradually became steeper, he was not reconciled to give up.

"call--!"

When everyone returned to the ground, they breathed a sigh of relief.

"Strictly guard." Li Yunpeng ordered.

"Yes!"

Li Yunpeng returned to the army and began to think about the situation in the underground palace.

This lizardman didn't seem to be very intelligent, his eyes were full of bloodthirsty madness.

It is completely different from Troy and others.

Is it that the situation of different ethnic groups in the dungeon is so different?

The quickest way to know the answer is to ask Troy and others, he dare not delay.

"Li Dun, arrange a plane to go to the Kunwu Mountains."

"Yes!"

......

A nuclear explosion occurred in the Kunwu Mountain Range, but it is located in a mountainous area and has a small impact area. The underground city group is located on the edge, and the radiation is almost negligible.

The inconvenient point is that the Kunwu Mountain Range does not have a military airport and is located in enemy territory, so Li Yunpeng has to detour through the western plateau to reach it.

There was no danger on this road. It avoided the Blue Dragon Imperial Air Force's reconnaissance, and the armed helicopter shuttled between the mountains and ridges. A few hours later, it arrived at the settlement of the underground city.

The sudden stranger made the underground people who had just established a foothold very frightened.

It wasn't until I saw Li Yunpeng clearly that he was a little relieved. After all, in Wulan Province, he possessed destructive power, but he didn't do anything. Moreover, he broke the siege of the ethnic group from the hands of the terrifying woman. Now he went to the meeting alone. It's not for trouble.

Troy put aside his business and hurriedly greeted him.

He no longer called his name directly, and said politely: "Guozhu Li, came from afar, is there anything wrong?"

Li Yunpeng wanted to ask others, but he didn't put on the pretense of being the leader of the country. "Leader of Troy, find a place and talk slowly."

Troy said, "Okay, please come with me."

The conditions here are definitely simple, only some wooden tables and chairs are placed, but the craftsmanship is very unusual. Before the end of the world, it seems that it is also from the hands of skilled craftsmen.

"This set of tables and chairs has extraordinary craftsmanship!" Li Yunpeng said with emotion.

"The vulgar production in a hurry should not be praised. If Li Guozhu likes it, I will order someone to craft a set and send it over." Troy said.

"Good talk, good talk." Li Yunpeng was polite, and then went straight to the subject, "Leader of Troy, a few days ago, I found an entrance to a dungeon in Wulan Province. I went in and tried it. All I encountered were ferocious beasts. Why is it?"

Troy was taken aback for a moment, and then he was relieved, "Hehehehe, Lord Li, you may not know the underground city well."

He changed his sitting position and started talking.

"Dungeons are not only inhabited by intelligent races, but also endless beasts. As the so-called one cave, one world, one strange sky, it is the situation of the underground world."

"Oh? What do you say?" Li Yunpeng came interested.

"In ancient times, when the mass extinction broke out, many creatures were looking for underground entrances, including some uncivilized beasts. It is recorded in ancient books. At that time, there were countless deep caves, and every cave and every cave became a world of its own. Countless ethnic groups swarmed in, and most of the creatures that did not adapt to underground life slowly became extinct, leaving only a few ethnic groups to continue."

"Later, after a long historical evolution, the independent underground world, either man-made, or because of changes in the earth's crust, slowly began to communicate, but every channel was guarded by the armies of the intelligent life group, isolating the beasts."

Li Yunpeng was surprised and speechless, presumably the hundreds of millions of human beings living on the surface could not have imagined that under their feet, there still existed a vast and vast underground world.
