I'm ordinary, but my sister is the strongest elf

After Sansan finished the regular maintenance, he immediately started the war mode and went to investigate after receiving Mu Yue's order.

The method of investigation is simple.

Destroy all suspicious locations and see if there are sinkholes underground.

In less than half a day, Sansan stood in front of a sinkhole.

She stood on the edge of the huge pit, looking at the bottomless tunnel like an abyss.

"Master, it should be here, right?"

Mu Yue used Xiaoyi to complete the visual sharing with Sansan.

Through Sansan, Mu Yue is now able to confirm that this place is a natural forbidden magic domain.

In the huge crater, it seems that the influence of the source of magic is isolated, creating the illusion of being outside the blue star.

Even strategic magicians cannot use magic here.

After all, the environment here is equivalent to outside the blue star.

It's no wonder that Xia Guo officials sent Gao Chengming, an ordinary soldier king, instead of a powerful magician to investigate here.

Around Sansan, a large number of troops appeared.

They surrounded Sansan, raised their guns, and the leader shouted: "This is the military forbidden area of ​​Xia Kingdom, please leave!"

Sansan glanced back, and then jumped straight down.

"It happened!"

The leader rushed over, then turned around and said angrily: "Someone broke in, what are you doing?"

A soldier at the back asked puzzledly: "No one saw how she got in? No one was seen at every checkpoint."

Hearing this, the commander looked towards the huge pit, and said solemnly: "General Gao has been down for more than two months, and their team has only brought two months of rations..."

"Calculate the time, if they haven't come out in a week, we can report the sacrifice."

The commander touched his chin, and then said: "Report the situation to the higher-ups for a decision."

"Yes."

……

After descending about 2000 meters in the giant pit, Sansan finally landed.

It was pitch black all around, but it didn't affect Sansan.

Around Sansan, there are six caves with a height of about 20 meters.

And next to it, there is a huge mechanical wreckage.

Sansan came to the wreckage, touched the metal fragments on the ground, and said, "Master, this should be a transport plane."

According to the damaged parts of the transport plane, it is not difficult to see that the transport plane landed successfully.

But after landing, the transport plane was attacked and it was damaged.

"San San, start exploring from the first cave on the left."

"Yes, Master."

Sansan turned and walked towards the designated cave.

After Sansan left, pairs of red eyes appeared on the wall of the huge pit in the center, and a large number of unknown creatures let out ferocious roars.

But these things were too weak, and were directly ignored by Sansan.

And Sansan had no vital signs, and was ignored by them.

In the cave, there is another cave.

The space here is very large, and it can even be described as vast.

In Sansan's sight, the space here is at least as big as a village.

There are some ancient buildings here, but through Sansan's perception, Mu Yue didn't find any impression of life activities here.

Sansan was walking in here, and it is reasonable to say that there are no creatures living in this place.

But why is there such an ancient building here?

Did the Blue Star humans have the technology to build a village 2000 meters underground?

Sansan was watching here.

There is no light here, and everything is dark.

But there is light at the end, and the closer you go to the end, the higher the surrounding heat.

After walking to the end, the surrounding sight became clearer and clearer.

At the end of this place is a river.

A lava river.

The surrounding temperature is also ridiculously high, with more than 400 degrees in the vicinity of Sansan, which is no longer the temperature that living things can survive.

After looking around, Sansan found that there was nothing special about this place, so she turned around and prepared to leave, heading to the second cave.

But suddenly.

There was movement in the magma.

A 20-meter-long tunnel worm rolled in the magma.

Terrible flames spit out from the mouth of the tunnel worm.

But it just heard movement outside, came out to take a look, and found that the things outside had no signs of life, and it returned to the magma.

Sansan searched for this guy's image on the Blue Star Network, and got some information about this thing.

This should be the sub-body of Elder Centipede, but some mutations have occurred, and it has extremely high heat resistance, and even the living environment has become magma.

As expected of a cosmic creature, this ability to adapt to the environment is truly invincible.

Seeing this scene, Mu Yue's expression became more and more serious.

It is a secondary pollutant, and it seems to have long-range attack capabilities.

In this kind of place, is Gao Chengming really still alive?

But the tunnel worms here also gave Mu Yue a bold idea.

Here, most of them are the lairs of some kind of insects.

This huge tiankeng may also be left behind by the body of this kind of bug.

But the diameter of this tiankeng is at least 200 meters.

If it is really left by a polluted body, how big should the body of this thing be?

The width of the worm is 200 meters, and the length is dozens of times the width... Isn't that a few kilometers in length?

If there are really polluted bodies with a length of several kilometers...

Mu Yue's brows sank.

No matter what, he has to investigate this so-called ancient ruin today.

Anyway, Sansan was inside, even if the little maid accidentally died, Mu Yue could still revive her.

The second cave is more exaggerated.

There is a terrifying fourth-level pollutant, which is also some kind of insect.

Now Mu Yue doesn't feel that these are the sons of Elder Centipede.

He even felt that the centipede elders were sub-individuals of other fifth-level pollutants.

Among the ten ancestors, the ninth ancestor was insects.

Ninth ancestor [Centipede Immortal].

This is also the ancestor who was rescued by the space magician in the last star trail strike.

If these polluting bodies in the tiankeng are daughter bodies, where is the mother body?Could it be the Centipede Immortal?

The space in six caves is equivalent to six villages.

Taken together, this is a town.

Dungeon?

Although there are some ancient buildings here, it seems that no one has lived in them for at least decades or even hundreds of years.

There were people living here about 1000 years ago, but they didn't live long.

Thousands of years ago, were humans trapped here to death?

Sansan continued to explore the third cave.

But as soon as she walked in, Sansan stopped in her tracks.

In front of him, a snake hovered inside.

According to Sansan's speculation, the snake was at least 50 meters long.

Fifth-level pollutants...

The pollutants in each cave are more severe than those in the previous one.

And it's not that great.

From level two, jump to level four, and then level five.

So what about the next cave?

Sansan didn't go deep into the third cave, but retreated directly and returned to the central pit.

This fifth-level pollutant was sleeping, and Mu Yue didn't let Sansan disturb it.

After all, Level [-] already has a certain IQ, so she won't ignore Sansan just because she doesn't have vital signs.
