Frost stood in front of the pit again, and just half an hour after Frost had withdrawn, the fog in the pit began to fill again.

And it will take half an hour for Meng Yue to arrive, even if it is the fastest.

As a last resort, Frost can only enter this pit to explore first.

This time, Ning Shuang didn't wear a chemical protective suit, she had already experimented just now, and this mist could be stopped by a gas mask, so naturally she couldn't break through her body protection true qi.

She didn't let Instructor Huang follow, no matter how strong Instructor Huang was, he was just an ordinary person, and he would definitely have to wear a chemical protective suit when he went down, if there was any emergency, she couldn't guarantee Instructor Huang's safety.

Standing in front of the pit, Frost used his perception to probe into the pit, the pit was not too deep, about ten meters deep, but other things were blocked by the fog, and Frost didn't perceive it too clearly.

After checking the gun handed over to him by Instructor Huang, Ning Shuang jumped and landed steadily at the bottom of this pit.

When he reached the bottom of the pit, a very faint smell suddenly burrowed into the nose of the condensation, as if it was the smell of gunpowder.

The surrounding fog was thicker than above the cave entrance, and it was a wall of earth for three years, and only the perception of frost could penetrate it.

Walking in the direction pointed by the perception, the surrounding light slowly diminished as the frost deepened, and finally fell into darkness.

Squeak squeak~

But not long after he went deeper, Ning Frost suddenly heard a strange sound.

Removing the bow box from his neck, the bow box quickly unfolded in Frost's hand, ejecting the sharp blade.

Frost didn't rush to condense the spirit arrow, the fluctuation of the spirit arrow was too obvious, and it was easy to expose itself.

Squeak squeak~

The sound is closer.

Frost could also feel something quickly approaching her.

Call~

The mist behind him fluctuated significantly, and the frost head did not return, and he had already thrown the bow blade behind him.

The next moment, the voice stopped abruptly, and the bow in Ning Shuang's hand also showed a slight sense of strain, but it was only for a moment.

Blood dripped down the blade of the bow, and Frost turned around, and two neatly cut unidentified corpses fell to the ground.

Putting the two corpses together, Frost didn't tell what kind of creature it was, but the sharp claws in the front and the sharp teeth in the mouth all showed the horror of this creature.

Squeak squeak~

There was another cacophony in the air

And also!

Frost stood up and mobilized her perception once more, but this time the fluctuations in her perception were no longer one, but one.

The mist was stirred up by the wind and waves brought about by the movement of these things, making it impossible for Frost to capture these things by sense at any time.

Shout~

The sound of piercing air continued to come into his ears, and relying on these sounds, Frost instantly judged the direction in which those things were coming, and the bow in his hand immediately danced a whirlwind of blades around him.

For a while, bursts of blood mist continued to explode around Ning Shuang, and blood poured in the air, but it was never contaminated with Ning Shuang's body, and was blocked from protecting the true qi of the body.

It's just that Frost resisted like this, and these things still didn't decrease when they attacked frantically for ten minutes, and these things still appeared in Frost's perception in pieces.

The fog around it became thicker, and presumably the fog above the town began to spread again.

It can't be consumed by these things here, so Frost Killing retreated from the direction he came from, intending to withdraw first.

"Help~"

Cry for help!

Ning Shuang suddenly heard a cry for help, and immediately stopped his retreat, although the sound was weak, but Ning Shuang could be sure that it was indeed a cry for help.

"Help~"

It's been passed over again, there is someone in the depths of this?!

After making sure that someone was in the depths, Frost naturally couldn't retreat, and she had to go in to save people.

Directly slashed forward and killed several monsters that rushed towards her, jumped a distance after condensing the frost, and immediately condensed the spirit arrow in his hand, charged it for two seconds, and shot it directly.

The monsters that were hit naturally couldn't survive, and the qi waves brought by the spirit arrows also set off many monsters, and a vacuum was immediately formed in the middle of these monsters.

Frost quickly ran through this passage, in this place she couldn't use her wings casually, originally acting in this place Frost relied on perception, if the speed was too fast, she wouldn't have time to remember the way back.

"Help~"

The voice came from the depths again, and Frost immediately accelerated his own running speed, and the monsters behind him couldn't catch up for the time being.

For five minutes, Frost ran at full strength for five minutes, but encountered a rather tricky problem.

The place where she ran was a dead end, and all in front of her were dirt walls.

How can it be? The distress call is clearly coming from here!

"Help~"

The voice came again, this time Frost heard it clearly, and the cry for help came from within this earthen wall.

Is this a wall?

Sensing the monsters getting closer and closer behind him, Frost decided to give it a try.

Once again, the spirit arrow was condensed, charged, and shot.

The moment the spirit arrow came into contact with the wall, it exploded directly into the dust, and a beam of light pierced directly from the location where the spirit arrow exploded.

Sure enough, it's a wall!

Frost fires another arrow, blasting a hole for human passage, and then quickly passes through it.

Frost, who had reached the other side through the hole, immediately pointed his bow at the hole and shot a spirit arrow, burying the hole with the mound of earth that had been blown down.

In this way, Frost finally got rid of the entanglement of these monsters.

Frost exhaled and began to take a closer look around.

It was surrounded by walls made of blue bricks, without the fog of the mission, and the ground was paved with bluestone under his feet, with a hollowed-out layer of earth overhead, and a bonfire on the surrounding walls was providing light for the space.

How does this place feel so much like the ancient tombs in those dramas on TV?

"Help!"

This time the sound was much clearer than what Frost had heard on the other side of the earthen wall just now, and it came from the passage on one side.

But running on the road, Ning Shuang was thinking about another question, how could there be someone in this place?

Getting closer and closer to the place where the call for help came, Ning Shuang finally saw who was calling for help.

It was two men, both carrying a large bag with hoes and straw ropes and things like that.

Looking at the surrounding environment, it is presumable that those two people are the legendary tomb robbers who specialize in making money from the dead.

Behind the two grave robbers was a tall object chasing them, and Frost immediately extended her perception to the thing.

Corpse!

After being taught by Lao Lin, Ning Frost immediately judged that this was a legendary evil creature based on the characteristics of the thing covered in rags and stiff in action.

Just about to raise his feet to deal with this evil thing, Condensation Frost stopped again, because these two people were not caught up by the zombie now, so Condensation Frost decided to watch the play for a while, anyway, listening to the cries for help from the two of them, the middle breath was quite sufficient.

"I said you bastard, if you don't want to come down, you have to come down, if you don't open the coffin, you have to open the coffin, shit, that cowardly thing doesn't know where to go! What else do you have in your bag, show it to me! ”

"Big brother! Not really! I've used everything I can! Let's find the exit! ”

"You bastard!"
