Bai Yuxi's reaction was so fast, he kicked the metal block of the cut superalloy gate, and rushed in with a dodge.

But it was precisely because of such a delay that when Bai Yuxi entered the passage behind the superalloy gate, the black shadow had already disappeared into a cave in the wall of the passage.

At the beginning, the base of Hualan Mountain was indeed excavated by a large number of mutant rats, and almost all the inside of the mountain was hollowed out.

But after the refurbishment and design of the engineering corps, in addition to some large cave spaces, it was preserved.

Some small rat holes have been filled with a large amount of high-grade cement, and the original caves have also been trimmed, cutting off the uneven rock walls, and laying cement, steel plates, compartments, steel columns and other supports, which has formed today's military base.

Therefore, theoretically speaking, it is impossible to leave this kind of cave on the wall of the overrun base built by the standard of permanent underground nuclear defense engineering, which is obviously dug out by rodents.

Bai Yuxi stepped forward to inspect the cave and found that not only had deep claw marks left on the rocks, but even the steel plates covering the walls had been torn apart, which was obviously impossible for normal creatures to do.

There is an anomaly under the base of Hualan Mountain, and there has been a mutant rat tide before, so if something happens again, a few high-risk rodents run out, causing the base to have to be closed, it is not surprising.

But the strange thing is that Bai Yuxi found that whether it was on the rock wall or on the steel plate, there were only claw marks and no tooth marks!

Everyone knows that rodents like rats, although they mainly rely on their claws to dig when making holes, they still use sharp fangs to help tear them.

It has nothing to do with whether their claws are sharp enough to tear through hard objects, but rather a biological instinct, and rats don't mind if they are clean and hygienic when they make holes.

So from the point of view of the absence of tooth marks, the rodent creature digging this hole is either a mutated mouse with a habit of cleanliness, or it has a high level of intelligence and can suppress its instinct to use both hands and mouths......

After all, in terms of work efficiency, the place where the claws can't be scratched, even if the mouth is not much faster, why bother to get a mouthful of stone slag?

sensed it, and found that the black shadow just now had already left through this cave, and was not ambushed inside, so Bai Yuxi simply drilled into it.

The cave that was dug up is not very large, the height is only about one meter four or five, and it can only accommodate a human who is not burly and tall, and he walks through it with his waist half-bowed, which shows that the size of the creature digging this cave will not be huge enough to go there.

The bottom of the cave is covered with thumb-sized gravel, which must have been left on the ground during the excavation, and it is fairly flat to walk on, but strangely enough, there are some drag scratches left on the rubble.

This cave is not long, only about ten meters, on the opposite side of the cave is another area isolated by the Chogokin Gate and the enchantment, judging from the location of the cave, it is obvious that it was not excavated indiscriminately, but a straight line distance closest to the passage on the other side.

This situation surprised Bai Yuxi.

Because if this cave is excavated purposefully.

Then it is obvious that the builders have a certain degree of understanding of the environment of the base.

At the same time, it has a precise positioning of the distribution of space, and has a pretty good sense of space.

Otherwise, it would be absolutely impossible to dig such an almost straight parallel cave in the weakest position of the rock mass so accurately!

This is obviously not something that a mutant rat, or an alien civilization creature with no understanding of the base environment, can do!

When Bai Yuxi walked through the cave, he found that a large amount of gravel was neatly piled up on both sides of the cave entrance, and there were some broken sheets, clothes, and items that could be used as containers scattered around.

Bai Yuxi picked up a dirty broken bed sheet, the thick army green cloth products were ground by broken stones, covered with large and small holes, and it was completely unusable, but it could be seen that someone had tied the four corners of this sheet to make a simple package.

Throwing away the sheets, Bai Yuxi's brows were furrowed more and more tightly.

Human, intelligent, and able to use tools, all signs point to some bad associations.

Could it be that the black shadow just now was a mutant rat-man who had been transformed, but retained human intelligence?

This kind of over-limit modified creature has been encountered by Bai Yuxi in the underground base of Tieting Village, and in the Seven Killings base in the Flower City of Eastern Guangdong.

But this is the Dragon Group's Hualan Mountain base?

I've never heard Xie Long say that the Dragon Group has set up relevant research projects.

Theoretically speaking, even the anomalies here are affected by spatial oscillations, opening a stable spatial channel.

It should only be rodent alien civilization creatures, why are there artificially created mutant rat people?

After looking around, this should be a dormitory for base personnel to rest, but in a space of more than 30 square meters, in addition to a few typical military-style metal frame high and low beds, there are only simple tables, lockers and other furniture.

At this point, the furniture had been piled up on the high and low beds and pushed to the corner of the room to make room for gravel.

On the other side of the room, on the wall, there is another cave, which, judging by the base map, should be another passage to the lower level.

Bai Yuxi continued to chase after him, and sure enough, outside the cave more than 20 meters long, a mountain of rubble was found, which made Bai Yuxi more and more sure of the diggers...... Whatever it is, it's sure to be familiar with the environment of the base!

Because living areas like this are relatively concentrated in the Hualan Mountain base.

There were such rooms on both sides of the passage they entered, but the excavators were located on the opposite side of a rock wall more than twenty meters thick, and located this room, the closest room to the outside world!

This shows that when the other party excavates the cave, it must have been considered and calculated.

In this way, after entering this living room, it only needs to dig a cave more than ten meters long, and it can enter another area of the base, minimizing the workload and avoiding repetitive work!

Bai Yuxi and Lingguang chased all the way along the traces left by each other, and found that this guy was so talented, he actually dug it all the way up from the research area at the bottom of the base!
