Shangguan Yuyan and the three of them cautiously entered the base, and at this time, a group of guards came in from the outside.

These guards are different from the previous ones, they are stronger, their armor is more advanced, and their weapons are better. It is clear that these people are elites, their special forces.

Seeing the battle armor on their bodies, Shangguan Yuyan and the others were very surprised. From the appearance, it can be seen that their warframe level is not low, at least the second-level warframe.

Who will be the civilization that can have a second-level battle armor? Shangguan Yuyan and the others were thinking in their hearts.

They did not act rashly, but found a more secret place to observe secretly. The prospector was taken to a room where there were a lot of instruments.

Moments later, a cyborg enters the exploration machine with his instruments. I stayed in for about ten minutes, and then came out with the instrument again.

The cyborg walked over to the lead guard and muttered. Shangguan Yuyan and the others immediately activated the translator and translated the language of these people.

"What did you find?" The lead guard asked.

"It's a detection machine, but it feels familiar!" The cyborg replied.

"Very familiar! What the hell is going on? The lead guard asked again.

"It's not good yet, I need further testing!" The cyborg replied.

A few minutes later, several more cyborgs approached the explorer, dressed as if they were a group of scientists.

Shangguan Yuyan and the others were puzzled why the scientists were all cyborgs. Could it be that it is to prolong their life.

Several scientists entered the exploration plane with the previous one, and this time it took a little longer to get in, a full half an hour.

Half an hour later, several scientists rushed out with great excitement. They looked at the lead guards, and their mouths kept yelling.

"Incredible! It's incredible! ”

"This machine has actually reached level 3 technology!"

"Quick! Report it now! This news must be reported to the patriarch! ”

Hearing the words of this group of scientists, Shangguan Yuyan could be sure that the armor of those guards was level two. However, Shangguan Yuyan couldn't figure out how a second-level technology instrument could invade a third-level technology exploration aircraft.

The group of scientists was so excited that they all watched around the exploration plane. Hearing that the exploration plane is a level 3 technology, the leading guards also attach great importance to it.

A moment later, more special forces arrived and surrounded the room. The matter of the exploration plane was quickly reported to the patriarch, and the patriarch immediately brought people to this place when he heard this.

Ten minutes later, the patriarch arrived here with a group of people. When they saw the test data with their own eyes, their excited bodies trembled involuntarily.

"Level 3 technology! It's really a level 3 technology! The old patriarch kept chattering.

"Finally see Level 3 technology!"

"Quick! Take a closer look and see which force this machine belongs to! ”

An old man said excitedly.

The cyborg scientists once again entered the exploration machine with their instruments. This time, the inspection was more thorough, and even the core database of the exploration aircraft was turned over.

But they were a little disappointed that they didn't find what they were looking for. The prospector has been modified by Tiess, and the contents of the core database have been copied away.

The old patriarch and several elders were very disappointed, they thought they could find some clues, but there was nothing in the database.

"You can't be wrong! There are not many civilizations that can have Level 3 technology! ”

"This is not necessarily, some of the vassal states of the hegemonic forces have mastered the third-level technology!"

"Did you send someone to check?" The old patriarch asked, looking at the guard next to him.

The leading guard saluted very respectfully, and then said, "I've already gone to check!" ”

By the time the convoy spotted the exploration plane, they had already sent out a reconnaissance team.

At this time, there are many fish-like armorers in the underground river, and they move very fast underwater.

Along with the Warframers are a number of robotic monsters, which resemble some sort of carnivore underwater.

These robotic monsters are more than twenty meters long, and they wag their long tails and search through the hundreds of passages of the underground river.

However, what they didn't expect was that Shangguan Yuyan and the others had already entered the base and were eavesdropping on their conversation.

Through the conversation between them, Shangguan Yuyan and the others learned that they were all Shui people. Those cyborg scientists, as Shangguan Yuyan guessed, are to prolong the life of the old scientists.

These scientists are the elite of their water tribe, and the old patriarch values their talents very much and does not want them to die of old age.

However, the biochemical technology mastered by the aquarists is not advanced, so they can only transform these scientists into half-human, half-robot monsters.

These aquarists were very excited when they saw the exploration plane, and began to think that Shangguan Swift thought that they were hungry for knowledge.

By looking at them, it was as if they were looking for something. Looking at their disappointed expressions, it seems that they haven't found what they are looking for.

Li Na wanted to step forward and ask face to face what they were looking for, and if they were the race that guarded the crystal stones.

However, seeing the second-level armor that these guards were equipped with, Li Na didn't dare to act rashly.

Although their Warframe level is a notch lower, there are simply too many of them. Those special forces came in very fast, and at first glance they were not ordinary fighters.

The old patriarch talked to the scientist for a while, and then left the base with the elders. Shangguan Yuyan and the three of them used the stealth of the battle armor to secretly follow behind the old patriarch.

After a while, they followed the old patriarch to a palace. The palace was much smaller than the underground river, and was supposed to be the residence of the patriarchs and ministers.

There are many guards at the palace gates, and these guards are also equipped with this second-level armor. Seeing their equipment, Shangguan Yuyan and the others were very surprised.

This civilization doesn't seem to be of a high rank, but their warriors are all equipped with second-tier armor. According to normal rules, the first-level warframe should be in their theory.

Shangguan Yuyan felt that this water tribe should be the race that guarded the crystal stone, and their battle armor technology was probably taught by the crystal stone guard.

They were so interested in the exploration plane just now, probably because they found that the technology contained in the exploration plane was similar to theirs.

If this inference is correct, they should be trying to find the owner of the crystal. Like the Meilan Clan, he was commissioned by the Crystal Stone Guard.

Thinking of this, Shangguan Yuyan decided to make contact with this water tribe. Shangguan Yuyan dragged Li Na and Yinyue down to a secret place and told them what they thought.

After listening to her analysis, the two agreed with her.
