After passing through the passage, the dome is another dome space.

The newly emerged dome space is similar to the previous space, with a diameter of dozens of kilometers.

Compared with the previous dome space, more remains can be seen in this dome space. The style of the remains is similar to that outside, and some shadows of Big Eye Brother's village can be seen.

But like the ruins discovered before, the ruins here are also covered in dust for many years without any trace of use or activities of Big Eye Brother.

"Are these places abandoned by Big Eye Brother?" A team member said while observing the remains.

Another team member was curious: "Why did they build such a huge dome space and why did they retreat?

Judging from the village and the warriors' technological level, it is not easy to build such a large dome space based on their ability alone, and it can even be said to be an impossible task.

I have a guess that maybe Big-eyed Brother's civilization has been in a state of degradation. They have forgotten the wisdom and science of their ancestors and have become the state of this primitive tribe.

But what exactly caused this to happen?"

"What I'm even more curious about is why the team of soldiers fled so far and went through the dome space to that village. What is the state of the Big Eyes civilization in the deep underground?"

Curiosity prompted the Titans to continue moving forward, and within twenty-four hours they actually passed through five dome spaces.

The area of ​​these dome spaces is similar, but as they go deeper, Big Eye Brother's remains are increasing.

In the fifth dome space, complete building retention has appeared.

These are some damaged round shell-shaped buildings, which have been covered with dust for a long time, but some damaged furniture can be found. The patterns engraved on them can make people speculate on the aesthetic tendencies of some of the Big Eyes civilization in the past.

Circles, curves, this civilization seems to have a strong preference for this. The most common patterns on furniture are circles, ellipses and curves.

Unfortunately, no matter how they searched, the Titans team could not find any books to record or any other recorded history.

"A part of the murals that have been completely destroyed can be found in the ruins that record history, but the ruins now look more like they have been abandoned actively, but nothing can be found to record civilization.

This makes people wonder whether these underground dome structures and buildings are used to live in, and what did Big-eyed Ge civilization experience a long time ago?”

The Titans camped here, and they had to make up for communication with the Expedition while resting for a short time.

They moved so fast that the communication robots could not fully keep up with their pace. Fortunately, after waiting for four or five hours, the communication robots arrived here in time and established a communication connection for the team.

After getting in touch with the Expedition again, the Titans immediately sent all the information back to the Expedition.

Feng Ting expressed concern about the continued action of the Titan Squad, but Xiaopang Brother proposed: "It is basically certain that the pioneer civilization is carrying out some kind of invasion of the underground world.

From our observation, the indigenous civilization of the underground world has degenerated to an extremely weak state.

At this time, the pioneers attacked the underground world and had to worry about their attempts.

We have to guess that the goal of pioneer civilization is not the aboriginal people underground, but to obtain some kind of resource.

If this resource is related to the pioneer's invasion of the earth, then we have to take it seriously.

Please give us some time to find the locations of pioneer civilizations to investigate what they have done.”

After weighing the pros and cons, Feng Ting still approved the operation of the Titan Squad and sent some support to the underground.

At the same time, the Expedition also drove out the continuous barren "Gobi" terrain, and it was the "ocean" of this planet.

However, the ocean here does not mean the same as the oceans on Earth. In fact, what the Expedition arrived was endless flowing liquids, which radiated lights of intertwined colors such as red and orange.

High radiation, high temperature and other toxicities have prevented the Expedition from entering the process. Judging from the drones sent out, no traces of biological activities were found in the ocean.

According to the information sent back by Lu Yu and his friends from the cities of pioneer civilization, as well as the mural information of the indigenous people sent back by the Titans from the underground world, Expedition has now had a rough outline of the planet.

Unlike the continuous migration of multiple land plates on the earth to form several continents, the land connection of this planet becomes a whole, occupying about one-third of the planet's area.

It is certainly unrealistic to cross the ocean to reach the other land coastline, and the Expedition decided to sail along the current coastline.

In this way, the Expedition will be further away from the underground world where Xiaopang Ge and his friends are located. In order to provide them with as much as possible, the Expedition will launch three small transport vehicles loaded with supplies to the underground to provide support to the Titan team.

After leaving this time, I don’t know when I will see you again. In order to prepare for the next action, the Titan team temporarily continued to stay in the dome ruins and waited for the transport vehicle to transport the supplies.

After waiting for nearly five days, the transport truck finally arrived at the Titan Squad. This time the transport truck carried a large amount of food and ammunition supplies, including two super bombs of 500,000 tons equivalent.

All machinery that was active in the pioneer field adopts modular design, with three transport vehicles directly connected to the base vehicle, and the Titan team once again heading towards the exploration of a good route.

It has to be said that this is a long march. While waiting for the supply, the Titan team has operated drones to conduct repeated reconnaissance. In addition to discovering some domestic garbage that is likely to be left by the group of warriors Big Eyes when they were rushing, there are dome spaces connected in series.

These dome spaces seem to be like a bunch of long grapes connected to each other. Some relics can be found in some dome spaces, but more dome spaces have been destroyed and are occupied by large luminous mushroom forests everywhere.

These relics along the way failed to provide everyone with any valuable information. Except for some relics that seem to have traces of excessively cold weapons wars, no valuable information was found.

Before we knew it, the Titans team had already penetrated more than 500 kilometers underground, and the depth of the underground could not be accurately calculated due to the degree of understanding of this planet.
