Chapter 421

And there's weak air convection.

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

Li Yunpeng observed for a moment and led people to explore deeper.

Underground space is barren and empty, but there are also some special plants, where there are abundant plants, and water flows through.

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

"Well?"

Li Yunpeng moved and came to a huge stone.

"Human bones?"

And it seems that, unlike the feeling of dying for a long time, bones are scattered everywhere.

Next to the bones, there are traces of burning.

"Human beings as food?"

Li Yunpeng frowned with frost on his face.

"Go

Under his leadership, the people continued to explore deeply. After a few kilometers, they found a nest community, in which many creatures lived.

Li Yunpeng fixed his eyes and saw that this group of creatures looked very much like upright lizards. The single body was four or five meters high and the image was ferocious.

Before he could observe for a long time, he suddenly saw that the whole group stopped and their nose twitched. Then he quickly determined their direction.

"Crouching trough, so sensitive to smell?"

"Boom..."

The lizards ran together, and the earth was shaking.

"Mou --!"

This group of orcs made a dull cry as they ran. Soon, in all directions, their similar groups emerged.

Li Yunpeng felt that he fell into the beehive.

"Withdraw!"

Look at the momentum, these things are not so easy to provoke.

Li Yunpeng and others ran along the way.

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

"Bang!"

Li Yunpeng's speed did not slow down and he drew his sword against each other.

There are several people behind them, and many senior evolutionists of the guard army draw their swords at the same time. No matter what kind of danger they face, they have infinite confidence as long as the commander is there.

"Kill --!"

With a roar, Li Yunpeng and the lizard man fought hand in hand.

As soon as he fought, he felt that the strength of these lizards was not simple.

"Come on, get out as soon as possible. It's troublesome to be surrounded." Li Yunpeng called.

Even these ordinary lizards are very hard to kill. They are not only thick skinned and have sharp claws, but also very agile and tenacious. If they cut off half of their shoulders, they all look at nothing. It's hard to imagine the consequences if thousands of lizards surround people in the distance.

"Commander, you go first." Li Qi kicked a lizard and said.

"Cut the crap and kill!"

Li Yunpeng fought hard. He could not count how many lizards he had killed with his knife. He finally rushed to the entrance of the underground city before the army came.

Two minutes after they went up, the passage below was blocked by the tide of lizards.

Like ape, Li Yunpeng and others quickly climbed up, leaving lizard man far behind.

The lizard man was heavy, but he didn't give up until the slope became steep.

"Hoo

When they returned to the ground, they were relieved.

"Be on guard." Li Yunpeng ordered.

"Yes

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

This lizard man doesn't look very intelligent. His eyes are full of bloodthirsty craziness.

It's totally different from Troy and others.

Is there such a big difference between different ethnic groups in the underground city?

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

"Li Dun, arrange a plane to Kunwu mountains."

"Yes

......

There was a nuclear explosion in Kunwu mountain range, but it was located in the mountainous area, and the influence scope was not large. The underground city group was located in the edge zone, and the radiation was almost negligible.

The inconvenient point is that there is no military airport in Kunwu mountain range, and it is located in enemy territory, so Li Yunpeng has to bypass the western plateau to get there.

It was a safe journey. Avoiding the detection of the blue dragon imperial air force, the armed helicopter shuttled between the mountains. A few hours later, it arrived at the settlement of the underground city ethnic groups.

The sudden strangers make the underground people who have just established themselves very scared.

It was not until he saw Li Yunpeng clearly that he felt a little relieved. After all, in Wulan Province, he had destructive power, but he didn't do it. Moreover, he helped the ethnic group out of the terrible woman's hands. Now, going to the party alone is definitely not to seek trouble.

Troy put down what he was doing and rushed out.

He no longer called his name directly, politely said: "Lord Li, come all the way, what's the matter?"

Li Yunpeng asked for help, but he didn't put on the airs of the Lord. "Trojan leader, find a place and talk slowly."

Troy said, "OK, please follow me."

The conditions here must be simple. There are only some tables and chairs made of wood, but the craft is very unusual. Before the end of the world, it seems that they were made by skilled craftsmen.

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

"The crude production in a hurry should not be praised. If master Li likes it, I'll order someone to make a set carefully and send it to him." Troy said.

"Easy to say, easy to say." Li Yunpeng said politely, and then went straight to the theme, "Trojan leader, a few days ago, I found an entrance to an underground city in Wulan province. I went in to test it, and all I met were ferocious beasts. Why?"

Troy was stunned, then relieved, "ha ha ha, Lord Li, you may not know much about the underground city."

He changed his posture and began to talk.

"There are not only intelligent groups living in the underground city, but also endless beasts. The so-called" one cave, one world, one different sky "refers to the underground world."

"Oh? How do you say that? " Li Yunpeng is interested.

"In ancient times, when the mass extinction broke out, many creatures were looking for underground entrances, including some uncivilized beasts. According to ancient records, when the earth collapsed, countless deep caves appeared. Each cave and each cave formed its own heaven and earth, and countless ethnic groups swarmed in. Most of the creatures that could not adapt to underground life gradually disappeared, Only minority groups are left to continue. "

"Later, after a long historical evolution, the independent underground world, or man-made, or because of the change of the earth's crust, gradually became interconnected, but each passage was guarded by the army of intelligent life groups, isolating the beasts."

Li Yunpeng was so surprised that he couldn't say a word. It must have occurred to hundreds of millions of people living on the surface that there is still a huge underground world under his feet.
