These three lines of defense are more powerful than the other. And Rui was able to pass through safely with the reconnaissance detachment, Wang Luochen felt that he was indeed a little uneasy. It seems that he will have to get to know his new subordinate carefully in the future.

After seeing the power of the three lines of defense, and secretly appreciating his new subordinate Ruyi in his heart, Wang Luochen set his eyes on the mountain in front of him, which looked like a morning glory.

Judging by the shape, the peak is supposed to be a volcano. Because it doesn't have spiky peaks. Its peaks were flat as if they had been shaved off in unison.

Of course, this kind of flatness is only from a certain point of view. If you look at it from another angle, you can see that it is not flat, but a trumpet shape with a high center concave and a high circumference.

So, its entire mountain shape resembles a trumpet flower. It's not standard, but it's really similar.

This is typical of volcanoes.

The reason for this shape is that the volcano is relatively young or still erupting. If it were an extinct volcano that was geologically old and had undergone crustal movement and weathering, the shape would not have been like this.

Because he had learned about this before, Wang Luochen was still able to deduce this.

Well, that's the question. Why? Why do the Tyrants have such a keen interest in this volcano? Is it true, as some people say, that there is gold here, and that they are only mining it here?

It stands to reason that this is a possibility. Because of the magma gushing, some of the heavy metals in the Earth's interior will be brought to the surface.

Gold, is one of them.

To say that they mine gold here is a fair point.

However, although gold is precious, there is no need to set up such a tight line of defense to protect it, right?

It's just a gold mine, even if it produces some gold, I'm afraid that people will come and rob it. But there's no need to work so hard, right?

Unless, they're not mining gold here at all.

Having seen the defense line laid by the Berserkers with his own eyes, Wang Luochen thought about their activities in this mountain again, and he was even more convinced in his heart that his previous judgment was not wrong.

The Berserkers are definitely going on here. So, he had to go and see it.

Convinced of his own judgment, Wang Luochen's determination to go deep into the mountains to take a look became even stronger. So he flew away from the meadow and flew up the hill to the higher part of the peak.

I walked some distance further and reached the halfway point of the mountain. He found that there were more buildings and more people. They and they are scattered all over the mountain, doing different jobs.

Some of them are responsible for guarding and patrolling, some are doing some logistics work, and some are doing some research work.

Anyway, there's everything. This makes the whole mountain look like a town of great size.

"Damn, so many facilities, equipment, and people are here. It shows that they have been operating this mountain for a while. It's really strange, what is there on this mountain that is worth their money?"

Wang Luochen wandered among these buildings and people, secretly observing. After basically figuring out the situation here, I was even more puzzled in my heart.

It's just that he knows that no one will take the initiative to tell him about his doubts. If you want to solve your doubts, you have to find the answers yourself.

And to find the answer, it's useless to just wander around here. He felt like he had to go up.

Because, he saw the cable car that stretched all the way up to the top of the mountain. and the spaceship that is constantly circling near the top of the mountain.

This made him feel that the top of the mountain was the most important place.

With this realization, he stopped staying and continued to fly upwards.

Towards the top of the mountain, he landed on the ground. He did this because he was afraid that the ships would see him with some kind of reconnaissance equipment that he didn't know about. Although his invisibility cloak uses the materials of the StarClan, and the level of technology is not low, after all, it is something thousands of years ago, and it may not be able to escape the detection methods of the Overlords.

In fact, this is because he is too cautious and too worried.

He does not understand that the development of science and technology to a certain level has its own inertia. That is to say, when science and technology continue to develop and reach a certain level, the difficulty of further improvement will increase, and the speed of development will also slow down. Perhaps, in thousands of years, it will not move forward much.

In other words, don't look at the metal used in his invisibility cloak thousands of years ago. The Tyrant doesn't have any effective means of detecting its existence.

Wang Luochen can't think of these things yet, although he will figure them out soon. Therefore, at this time, out of his usual caution, he chose a safe way to travel.

After landing on the ground, the rocks and buildings on the ground can play a protective role for him, and it is safer for him to fly alone in the air. That's why he chose to land on the ground.

Once on the surface, he continued along the cable car line and soon approached the top of the mountain.

There are also many buildings at the top of the hill, and there are also many tall towers. These towers are hung with powerful lighting fixtures that illuminate hundreds of meters of the surrounding area as bright as day.

With the help of them, Wang Luochen saw that these towers all had outstretched cross arms. On each cross arm, there is also a cage that can send people to the bottom of the huge sinkhole at the top of the mountain.

Many Berserkers keep going in and out of the sinkhole through the cage.

Seeing this scene, Wang Luochen couldn't help but think that it seemed that the secret was in this sinkhole.

If he wanted to know what the secret was, he had to find a way to get to the bottom of the sinkhole.

To this end, he quietly walked to the bottom of the tower, intending to observe the situation under the sinkhole before going down.

At this point, he became more cautious due to the intense light in the depths and the crowd of Berserkers.

He walked very lightly, lest he make a little noise.

Plus, he'd have to dodge the guys who came at him. After all, although he is invisible, he is not truly invisible.

Others can't see him, but they can touch him. If someone else comes towards him and he doesn't run away, then he will actually come into contact with the person and hinder that person's progress.

In this way, others will definitely be able to discover his existence. So, he had to be careful not to let others bump into him.

Out of caution, he walked very slowly. From the side of the cable car station to the bottom of those towers, and from there to the edge of the sinkhole, a distance of more than 200 meters, he walked for more than ten minutes before he finished.

However, when he got to the edge of the sinkhole, he didn't need to be so careful. Because, when he gets here, he can fly again.

He jumped down from the edge of the sinkhole, and slowly descended along the cliff of the sinkhole with the support of the magic circle, and soon fell hundreds of meters to the bottom of the sinkhole.

There, it's still brightly lit and busy.
