There is also an indissolvable mortal enmity between the three types of goblins, large, medium and small, and the three types of lizardmen.

The Greyskins and Blue Pedro are also undying rivals, they are enemies of each other, but they also tacitly attack together from time to time, and other races that dare to invade their territory......

Therefore, it is impossible for a wide variety of underground races to coexist in the same space.

However, they would rather huddle together and kill each other than leave the place and find a safe environment to live in without old enemies...... This is likely to be due to factors such as the scarcity of livable conditions, water and food.

But from their gathering place, they all surround the perimeter of this underground hollow group.

It seems to be guarding the few super giant underground caverns in the middle, and there may be some other reason why they are gathered here.

Or rather, what is there in the central area of this underground cavity that they need to protect?

Or is it that the situation is now relatively safe, and it may be more dangerous to leave here and live farther away?

Bai Yuxi and Lingguang, who couldn't figure out what the situation was, didn't dare to rashly approach the core of the underground cavity, because even the outer areas were already quite dangerous.

Although with the combat power of the two of them, they have not yet encountered an object that they can't beat.

But the problem is that in this underground cavity inhabited by hundreds of races, the density of biological races is too high!

With their supernova stealth ability, they can't completely avoid being detected by underground creatures.

And if they really want to fight, they can't help but quickly eliminate those creatures with all their might.

In this way, they will be delayed, and as more and more underground races arrive, they will fall into a time-consuming and labor-intensive protracted war.

Moreover, even Bai Yuxi didn't dare to say that he could calmly retreat under the crowd tactics of the underground race!

Because, the closer you get to the core area of the Underground Cavity Group, the more dangerous these creatures are!

Greyskinned Pygmy and Blue Pedro have an average D~C grade, and Ichthyosis and Swamp Toad have an average C~B grade.

The average small goblins only have E-level combat power, and a few can reach D-level, while the big goblins have an average D-level combat power, and a few have reached C-level or above combat power, and when they reach the giant goblin, they have reached the average B-level combat power, and a few have reached the level of A-level or above combat power.

As for the three kinds of large, medium and small lizardmen, it is the same, and it is not excluded that among these biological groups, there are super A+ level leader individuals.

The creatures that have survived the melee for many years have undoubted combat effectiveness, and coupled with their huge numbers, even Bai Yuxi does not dare to provoke them easily.

Bai Yuxi and Lingguang, who were discovered by the underground races with high combat power levels one after another, and had to quickly evacuate the other party's gathering area, couldn't help but glance at each other with grim faces after returning to the outer area of the underground cavity group.

Obviously, Lingguang also sensed that the existence of these creatures was a threat to the Hualan Mountain base!

If it weren't for the fact that these underground races were restrained by each other, a random race would launch an all-out attack on the exit of the anomaly, with their huge number, I am afraid that they could easily destroy the defensive position formed by just two or three thousand Yan group warriors!

Not to mention, with the danger level of these underground creatures, it was impossible for those middle and low-level over-limit warriors in the Yan Group to be stopped at all, after all, even their captains and vice-captains, Xie Long and Zhou Hao, were only worthy of reaching the B-level or above combat power!

The most terrifying thing is that Bai Yuxi and the others have only explored a small part of the underground cavity group, and there are still a large area of unknown areas around them that are in a state of fog, and they haven't even found those mutant rat people's settlements!

That's a big problem!

The Hualan Mountain base is not like the Dragon Palace base, and Bai Yuxi can also use the huge combat power of the Alberon Civilization Sea Clan to suppress these underground creatures with razing.

Even if Bai Yuxi can summon a large number of sandman warriors to help.

But in the face of such a huge group of creatures, the situation is no longer something that he can solve alone!

Prepare to immediately withdraw the entrance to the anomaly, inform Xie Long of the information, and ask them to report to the top of the Yan Kingdom immediately.

But Bai Yuxi thought about it, and then made a temporary decision, and the two of them quietly on the periphery with Lingguang, one of them caught a prisoner, and was ready to take it back to slowly "interrogate".

Seeing the safe return of the two of them, Xie Long, who stayed at the entrance, couldn't help but breathe a sigh of relief, because the "scout bees" released had all been wiped out, and they were completely destroyed by the underground race that found this strange object.

At the same time, after Bai Yuxi and the others left, the entrance to the anomaly point was also attacked several times.

If it weren't for the fact that Bai Yuxi had left a large number of fire beasts to guard the passage in advance, I am afraid that when they came back, they would see corpses all over the field and rivers of blood.

He informed Xie Long of the information he had discovered, and asked him to immediately inform the high-level officials of the Yan Kingdom to find a way to take countermeasures.

The situation in this underground space is no longer a situation that a certain person or a certain over-limit force can deal with alone!

Xie Long's face changed when he heard this, and he nodded to Zhou Hao beside him, and let him go through the space channel in the anomaly point and return to the Hualan Mountain base on the other side of the earth, and warn the higher-ups.

And Xie Long, who stayed behind, looked curiously at the two captives in the hands of Bai Yuxi and Ling Guang.

One of them is the kind of "mite essence" that is no more than a foot tall, but has a huge head, a small body, and short limbs, and looks like a rotten blueberry!

This little monster is probably the weakest humanoid creature in the underground world.

The entire race generally stays at the level below the F level, but the number is even larger than the sum of the hundreds of underground races!

Almost every corner of the underground space is filled with this flea-like creature, densely packed with space in every cave and rock crevice!

A group of people curiously gathered around the creature, which looked like a blue lion's head meatball, and watched Bai Yuxi interrogate it with that strange "underground lingua franca".

The interrogation process was omitted, because this creature with the appearance of a person or two was extremely timid, and Bai Yuxi only scared it a few words, and began to hear it screaming and explaining everything.

Just looking at Bai Yuxi's expression, he was obviously very dissatisfied, after all, he was just a low-level creature living on the periphery, and he was not qualified to know too many secrets.

So Bai Yuxi set his eyes on another captive, an underground dwarf!
