The speed of the Expedition was affected mainly because of the results of the Titans' inspection.

After gene interpretation, the blood samples of the underground humanoid creatures collected by the Titans team were completely confirmed to be two completely different creatures from the pioneers.

Later, during the exploration activities of the Titan Squad, it was discovered that the humanoid creature seemed to have begun to consciously contact the Titan Squad indirectly from the beginning of observing the Titan Squad's activities.

By leaving some symbols or objects, humanoid creatures guide the Titan team to discover something regularly from blindly exploring the underground world.

Some places underground present a strange aura of death.

These places are very hidden, mostly located in certain underground canyons, cliffs and other areas.

Unlike the vibrant feeling of other places where the Titans have been to, these places can feel the cold before they get close to them, while the rich animal and plant resources in the underground world cannot see any plant and animal animals or even a bug that takes the initiative to approach these places.

So that clear colors can be seen from afar.

After observing, the Titans saw shocking scenes. In the hidden terrain, there were artificially carved architectural relics and corpses that had become fossils.

What's even more strange is that these places full of death breath may be places where humans can enter from the detection instruments of the Titan Squad.

The radiation level and pollution level in these places are far lower than the lush vegetation underground and the high-intensity radiation on the ground. To some extent, the radiation level has reached the level of the earth's environment.

After some discussion, Xiaopang decided to build a frontier base nearby first, and then personally led some Titan drivers to the underground for investigation.

A large number of equipment was transported from the Expedition to the ground by drones. Twelve volunteers were drawn from the Titan pilot and led by Xiaopang and Chen Tianming to go underground for investigation.

The Expedition stayed for too long. For all reasons, after putting down the expedition team, the Expedition left at full speed in the predetermined direction.

The Titan mecha sent this time is much stronger than the ones that have already reached the ground. The remote-controlled Titan mechas underground all use miniature mechas, while the manned team has adopted high and low configurations in order to have more powerful firepower.

A total of twelve manned Titan mechas, including Xiaopang and Chen Tianming, among which Chen Tianming and the other two drove three heavy firepower support mechas named "Thor" in 500 tons. The design of the Thor mecha is Lu Yu copied the design in a popular game, using a large number of rockets and two electromagnetic guns as the main firepower. The power is provided by collecting high-radiation ore refined fuel engines in the field of refining pioneers.

The remaining nine mechas are all 100-ton mechas, with good protection and firepower, and relatively balanced combat power.

But at the same time, in order to deal with some flexible and changeable tasks, ultra-miniature Titan mechas of less than ten tons are also carried as backups, which are usually stored in frontier bases or operated by remote-controlled drivers on the Expedition. When needed, the driver can enter the cockpit.

The frontier base is directly based on a small base spacecraft, which is like many base cars in games. After Lu Yu's careful design, a small base can be quickly developed that can provide command, communication, medical care and basic production capabilities.

For the Titan mechas who were inspecting the underground world, the most important thing about this base is to process high-concentrated fuel.

Because the remote-controlled mechas before were all micro mechas, the energy required was only replenished by drones, while the manned teams now use big guys, and their energy consumption increased almost by a geometrical time.

It took several days to arrange the front-line base. After the base ship was unfolded into the main building, a drill bit went deep underground to start mining radiation ore to provide fuel to the base and mechas.

Brother Xiaopang led everyone to build a wall for the base, and a power grid was also laid on the wall to prevent the strange creatures underground from approaching.

Twelve warriors of underground adventure gathered in the frontier base, where space is limited, so it is naturally impossible to conduct various partitions in a complete manner like the Expedition spacecraft.

The war room is also a conference room or even a part of the dormitory. Fourteen people crowded together. In addition to having a meeting, they also had to hurry up and replenish their energy.

In this environment, even drinking water is so precious that the most delicious food that everyone can enjoy is just a cake roll with a box of milk.

This is already a luxury for the Titan Reconnaissance Team, because in order to save resources, most of the supplies they carry are compressed foods and high-energy foods with high energy density but extremely poor taste.

Brother Xiaopang looked through the pictures taken by the drone and said, "Those humanoid creatures deliberately guide us here, probably to let us discover those relics.

It seems that the identity of their indigenous people can be basically confirmed, and these relics are probably their former homeland where they were destroyed.

Although we have already reached the ground, I personally do not recommend that people go down to the ruins. It is enough to use remote control to allow the Titan mecha to enter."

One team member said: "I agree that although these relics can arouse our curiosity, we may not be able to fully guess the ideas of the Aboriginal people.

Different intelligent creatures form different civilizations, and the difference in the way of thinking of each intelligent creature is probably much greater than that of people in different places on the earth.

We have few people and must be cautious.”

There were no other opinions on the investigation of the ruins, and as the investigation deepened, the history of pioneer civilization entering this planet was gradually unveiled.

Judging from the narratives such as murals found in the remains, at the beginning, this planet had a relatively prosperous civilized society and was spread throughout the planet.

It is difficult to distinguish the level of scientific and technological development of this civilization from the mural narrative, but a star map about this planet was found from these murals.

The star map is somewhat similar to the ancient star map on Earth. This is definitely news that excites everyone, because the pioneer civilization has its own unique understanding of astronomy and coordinates, and it is difficult for humans to crack this system of the pioneer civilization without taking risks.
