These caves also lead to some huge underground spaces, where there are also many mutant beasts, and the internal evolutionary resources are also rich, but these are not Lin Yifan's destinations.

Originally, Lin Yifan planned to go deeper slowly, but after probing the location of the branch of the little green spirit body and going underground for about 100 kilometers, he directly gave up this idea.

That's a vertical depth of more than 100 kilometers, and I don't know how long it will take to enter alone.

So directly use the fastest way, or teleportation.

Using the connection of the spirit branch, the space door was opened directly at the location of the spirit branch.

As soon as he came out of the space door, it was a branch of Xiaoqing's spirit body.

After letting the spirit branch explore on its own, Lin Yifan and Xiaoqing carefully looked at this place.

It's still an underground space, but it's self-contained, with lots of vegetation, and it's a bit ancient.

Even some plants that have long been extinct on the surface of Blue Star, plants that evolved and mutated after these plants.

In fact, there are also a lot of underground spaces in other places.

Moreover, in those underground spaces, there are also many mutant beasts hidden.

Just like here, more than 100 kilometers deep underground, it is too deep, even if it is a meteorite annihilation crisis, it has not had much impact here, basically there is no change.

Lin Yifan has also been to the underground space in other places, but not too deep, after all, it is too deep to enter is also a problem, the passage extends in all directions, not vertical even, just detour, you have to go around dozens of times the distance.

Although Lin Yifan also knew that the deeper underground these places, the more strange mutant beasts or other plant species existed.

But he didn't have the energy to dig deeper, meaning the evolutionary team was interested in exploring it themselves.

However, few evolutionary teams will enter the underground space so deeply, and it is already very difficult to enter a few kilometers underground.

After all, in the intricate underground space, it is very easy to get lost, and the crisis is almost several times more than the ground.

In addition, food cannot be guaranteed, if you encounter a crisis or accident and are trapped in a certain place, then it is a big deal, just wait for death.

Therefore, generally no evolutionary team will deliberately go deep, and will only enter the underground space that is not too deep from the ground.

For example, now Lin Yifan entered more than 100 kilometers underground, which means that there is Xiaoqing's spirit body branch, and he has penetrated here in advance.

If human evolutionaries come here, not to mention the dangers along the way, but to say that they can get here, then I don't know what the Year of the Monkey is!

Therefore, Lin Yifan was also unwilling to enter the depths of the underground, and did not arrange a task for the members of Qingshan to go deep underground.

At most, some of the surface of the underground space is developed, about 10 kilometers underground, and the rest has not yet been involved.

These underground spaces alone are enough for human evolutionaries to explore.

At this time, the reason why Lin Yifan entered here was mainly because the news from the Xiaoqing Spirit Body branch showed that traces of a special civilization had been found here!

That's why Lin Yifan became interested and came to check it out!

After all, civilization is not so easy to produce, but in the depths of more than 100 kilometers underground, there are traces of new civilizations, this matter is very strange, it is necessary to come and investigate.

This space is very large, and the vegetation is also very dense, all of which are some special plants that do not exist on the ground, and after mutation, they are more tall and straight.

Coming to the location mentioned by the Little Qing Spirit Body Branch, a pyramid appeared in the jungle!

Yes, it is indeed a pyramid!

This underground space is already very large, with a height of more than 200 meters, but the height of this pyramid actually occupies 180 meters!

The materials used to build this pyramid are all huge rocks, each rock must be one meter thick, and the length is more than one meter!

At a depth of more than 100 kilometers underground, there would be such a special pyramid!

On one side of the pyramid, there is a 20-meter-high step.

These steps are specially machined and only about 40 cm high, stretching up and have a magnificent entrance!

Lin Yifan and Xiaoqing looked at each other and saw each other's doubts.

Needless to say, Xiaoqing definitely had no memory before.

But in Lin Yifan's understanding, he had never heard of the existence of pyramids underground!

Since it's here, go inside and take a look!

Walking up the steps, I slowly came to the entrance of the pyramid.

The entrance has several huge stone pillars, topped by a huge stone slab above.

The gate of the pyramid is a stone slab nearly 10 meters high on two sides, which slowly pushed open, leaving a cloud of dust behind.

When the gate opened, a long passage appeared in the rear.

On the stone walls on both sides of the passage, stone paintings are carved.

The first stone wall on the left side that I just entered is actually depicted by humans!

But the other side of the corresponding, the stone wall on the right, depicts not humans! It is a group of special beings similar to humans.

These special creatures also walk upright and have limbs, but they are taller than humans.

And these special creatures all wear masks, and there are special equipment on their bodies, depending on the situation, it seems that the technology is very advanced!

On the mural on the left, the human decoration is more shabby.

Although it is a piece of armor, there is no element of technology at all.

Both sides were holding weapons, and the human race was basically cold weapons, about a dozen people, either long knives or long swords.

The special creatures on the other side have blades in their hands, which seem to be blades connected to their armor, and they also seem to have special technological weapons on them.

As he advanced, the mural in the rear seemed to confirm Lin Yifan's guess that he was indeed carrying a special scientific and technological weapon.

Because both humans and this special creature are fighting.

Moreover, they were fighting in this pyramid, and their enemies also surprised Lin Yifan!

It turned out to be an alien beast!

The opponents of the two sides fighting are all alien beasts, exactly the same as the alien beasts that appeared on the dark star!

Humans rely on cold weapons, real swords and real guns to fight with alien beasts.

On the other side, special creatures use blades and technological weapons to deal with the endless stream of alien beasts!

The passage is long, the murals are numerous, and there seems to be more than one battle recorded.

In the picture, both parties are bleeding and fighting in the pyramid, and finally from the battle of the alien beast, they have killed the encirclement.

And at the top of the pyramid, there seems to be a throne.

On the throne, there is a special item.
