During the time of transforming the mobile fortress, even if the inner world was extremely vast, it was enough for Ye Zan's probe to sweep every corner.

Therefore, for the situation in the inner world, even if Ye Zan has not really stepped into it, he may have a clearer and more detailed grasp of the situation than the creatures in the inner world.

What is especially important is that the information that Ye Zan has is all information obtained from real-time monitoring.

For example, at this time, in the face of Lilia's "desperate strength to eat", the spatial passage that was opened could only allow one person to pass through. Ye Zan could clearly know the specific location of the passage in the inner world, whether there was any danger around, and the distribution of monsters in the center of the earth beyond.

It is precisely because of this confidence that Ye Zan does not mind not being able to use the war fortress, and does not mind entering the inner world "without protection" like this.

"Alright, I'll go first, and you'll follow. Ye Zan greeted everyone, and then flashed into the spatial passage, and the figure soon disappeared completely in the eyes of everyone.

In the blink of an eye, Ye Zan had already passed through the "narrow" spatial passage, and his figure appeared in the so-called inner world.

As observed by the probe, the light in the inner world is dim, and there is a luminous body that acts as a sun hanging in the sky "overhead".

The luminous body that was responsible for the sun, from Ye Zan's point of view, hung in the sky, but in fact it was at the center of the entire barbaric world.

In other words, if you think of the savage world, you can see it as the kind of planetary body in a technological world. Then, the position of this sun in the inner world is where the "core" of the planetary body is located.

This "sun" is not a star in the world of science and technology, nor is it the manifestation of the Great Dao in the world of monasticism. It can indeed shine, but it is not enough for this inner world to have the same daylight as outside, and there is not even a change of day and night.

In addition, since this inner world is located inside the "planet", it is theoretically possible to fly to the sky on the other side of the world as long as it keeps flying upwards.

The geomorphology of the inner world is not much different from other "normal" worlds, and there are mountains, rivers and even oceans. Moreover, because the world is very vast, it is generally impossible to see the obvious curvature on the shape of the earth, the same principle as on the surface of the planet.

In terms of biology, from plants to animals in the inner world, there are all kinds of scales and armor, wet eggs, but the size is much smaller than the creatures in the outside world. Perhaps in terms of the size of the creatures, this inner world is more like a "normal" world than Ye Zan and others.

In particular, Ye Zan had already discovered a large number of relics of civilization in this world through the detection of probes. According to estimates, the history of those civilization relics is very long, and they all belong to the existence of millions of years ago.

In other words, millions of years ago, there was a real intelligent race that had formed a civilization.

As for whether the intelligent race did what it did to die and perish, or whether it was destroyed by the demons outside the sky, it is not something that the detector can detect.

After coming here, Ye Zan just glanced around, and didn't go around too much, and directly released the war fortress from the small world first.

The War Fortress appeared near the Space Passage, directly placing the Space Passage inside the War Fortress.

With the war fortress, Ye Zan is completely free of any danger in this inner world.

Although judging from the detection feedback of the probe, there are many monsters in the inner world, but none of them can compare to the original octopus monster. Ye Zan relied on the powerful firepower of the war fortress to be able to easily kill the octopus monster, and naturally he didn't need to worry about the existence of those who were not as good as the octopus monster.

After the war fortress was released, everyone outside who received Ye Zan's message also walked in from the spatial passage. In addition to the Lin family siblings, Casaro and others also followed, and finally there was Lilia, who was only the size of a finger.

For this inner world, there is no one who is not curious, especially knowing that there are still relics of civilization, so naturally they will not miss this opportunity to explore.

As for the mobile fortress of Casaro and the others, as well as Lilia's hanging garden, they were all left on the side of the spatial passage. Only the mobile fortress of the Lin family sisters and brothers, since it was docked on the war fortress, was brought over by Ye Zan through the small world.

However, there is a war fortress, and Casaro and the others do not need to move the fortress.

"This underground world doesn't look much different from the outside!" Lin Mumu said with a little disappointment as he looked around.

"Otherwise, what do you think it should be, the dark void is still full of flames or something! Even then, it's not unusual to us. Ye Zan replied casually, and after Lilia closed the passage, he drove the war fortress to move.

Since he had already mastered the situation in the inner world, Ye Zan had already set the goal of exploration before entering here.

This inner world is not such a secret existence, otherwise those extraterrestrial demons would not have the means and ability to summon octopus monsters.

In other words, during the period when the Outer Heaven Demon controlled the barbarian world, not only did they scavenge various resources from the outside, but it was definitely impossible to let go of this inner world.

Among the messages sent by Ye Zan's probe, there are many traces that should be left by the activities of extraterrestrial demons. For example, some of the "recent" mines that have been mined, and the remains of some monsters that have apparently died in hunting, are all evidence that the Outer Demons have been here.

And this means that in terms of valuable resources, Ye Zan may not have much to gain in the inner world.

Of course, this is not to say that there will be no gains at all.

After all, Ye Zan's group is different from the size of the demons outside the sky.

For example, having so much money in the tens of thousands of dollars may be a huge amount of money for an individual, but it is a drop in the bucket for a billionaire.

In a phrase that people often use as a joke, it is "a little bit of your finger is enough for us to struggle for many years".

On the side of the demons outside the sky, in terms of looting resources, at least they are all forces like the towers of the few rings. And the Ring Tower, which is equivalent to the sect alliance of a domain in the cultivation world, is an existence whose size is far beyond that of an individual.

Therefore, there may be some resources that the Outer Demons disdain to collect with the effort, feeling that they can get more from elsewhere with the same effort.

However, for Ye Zan and his party, it was a pretty good harvest.

In addition to resources, there are also those relics of ancient civilizations.

Those relics of civilization, if there are valuable things, must have been looted by the demons outside the sky like resources. But in the same way, what was missed by the evil demons outside the sky was still worth exploring and looting by Ye Zan and his party.

Moreover, for the ancient civilization of millions of years ago, Ye Zan thinks that it is still worth researching and excavating even from the aspect of "humanities".

"Let's go to the nearest ruin, although it has been excavated by the Outer Demons, there should be something left. Ye Zan explained to everyone the next goal.

"Alas, the demons outside the sky are really hateful, so we can only pick up the leftovers from them. Lin Mumu complained jokingly.

"Why do you say so ugly, what do you mean by picking up what they have leftovers? Ye Zan smiled and changed Lin Mumu's words to another one.

"Hey, that's a little better. Lin Mumu said very cooperatively.

After a few small words, the war fortress had come to the vicinity of the ruins, but it had finally attracted the first wave of enemies.

As I said before, in this inner world, in addition to those "normal" creatures, there are many octopus monsters.

And the huge size of the war fortress is an extremely obvious target in the sky, which will naturally attract the attention of those monsters.

Although the War Fortress and the Octopus Monster are about the same size, they are very different in their ability to deter other monsters.

That octopus monster, as a powerful terrifying creature, exudes that terrifying aura all the time. The other monsters with weak strength, as long as they sensed the terrifying aura, could directly run as far as they could.

And the war fortress, even if there is artificial intelligence, is still a dead thing in the end. Its strength can indeed easily kill the octopus monster, but it will not emit any aura outward. In particular, when it is not in combat mode, the war fortress is just a building flying in the sky.

Of course, if Ye Zan was willing, he could open up some of the restrictions on the war fortress and let the corpses of the demons outside that day emit energy fluctuations, which would also deter and disperse those monsters.

It's just that Ye Zan is also very curious about those monsters, so naturally he won't refuse them to deliver them to his door.

"Those monsters, they look disgusting! It reminds me of those cultists in the small world, the demons from outside the world. Seeing the monsters coming from a distance, Lin Mumu couldn't help frowning and complaining.

Just look at the monsters that surround the fortress of war, there is almost nothing that conforms to the aesthetics of human beings, or they all seem to be deliberately contrary to the aesthetics.

Some monsters look like huge eyeballs, and there are tentacles floating behind them like blood vessels and nerves.

Some of the monsters are like half-melted wax figures, which are not beautiful shapes in the first place, and the result is all kinds of distortions as if they were melting.

Some monsters, as if they were made of countless corpse pieces, had their arms and legs in a position that made people look awkward, and they were all waving there.

There are also monsters, like a bunch of long insects together, and they can't see where the front and back are, and they can't see where the mouth and eyes are. Moreover, the body of the long worm was covered with stinking mud-like slime, which kept dripping downward when it flew over.

The only thing these monsters have in common is that even if they don't have wings on their bodies, they can fly freely in the sky.

Just like what Lin Mumu complained, these monsters are purely in terms of image, and they are indeed similar to the transformations of those evil gods in Ye Zan's small world. At least, even if they have a difference in appearance and shape, they are all the same and disgusting, as if looking at them will make people feel that their eyes are polluted.

"Well, that's how I feel, that's why I brought them here. I don't know if these monsters were left behind by the demons outside the world, or if they were bred in this world. Ye Zan agreed with Lin Mumu's words, and at the same time said his own reasons.

As those monsters got closer and closer, the war fortress finally launched an attack on the monsters under the command of Ye Zan. Those suspended turrets were distributed in all directions of the war fortress, and one after another cannon light sprayed out in an instant.

Before, the octopus monster that was summoned couldn't resist the attack of the levitating turret. Now these weaker monsters, in the face of a series of cannon lights, naturally it is difficult to perform better than the octopus monsters.

In the blink of an eye, the levitating turret stopped firing, and the monsters were all in shambles.

Moreover, those monsters, although they seem to have the same origin as the octopus monster, are not as difficult to kill as the octopus monster.

After being riddled with holes by the cannon light, those monsters lost their breath of life without accident and fell to the ground one by one.

At the same time, Ye Zan also sent a batch of flying machines to collect genetic samples from the corpses of those monsters.

"That's it, you see in the distance, those monsters are starting to run away!" Casaro and the others pointed to the distance and motioned to Ye Zan.

For this result, Casaro and the others were not surprised, after all, the huge octopus monster before was bombed to slag, not to mention these monsters with worse strength. The only thing they were a little surprised about was probably the reaction of the monsters in the distance, who actually seemed to be a little wise.

This kind of running away when the situation is not good is different from the instinct of the beast to seek advantage and avoid harm, but it is a kind of ability to judge the situation. Being able to judge that you can't hit the south wall according to the situation without hitting the south wall is not a kind of wisdom!

"What is this! Aren't those monsters in the small world conjured up by the demons outside the world with those evil god believers? These monsters, who knows how they came about, maybe they were also turned into by whom. Lin Mumu said with a strange look.

Ye Zan's side had already recovered the flying machine that collected the genes, and said to everyone: "Since they have run away, let's let them go first, let's take a look at this ruin first." ”

The ruins of civilization below, about the size of a war fortress, look like a city. Therefore, when the war fortress came to the sky above the ruins, it almost shrouded the ruins in the shadow of the fortress.
