The four of them went directly into the rear karst cave without looking back, and the branch karst cave was not small, and they walked forward in twos and twos.

But the squeaking sound behind him was overwhelming, like a bone appendage.

Qin Lang and Zhou Shaohua turned around and sniped from time to time, scolding while fighting back.

"These rat cubs are really terrible, Lao Qin, I think we have to explain here today."

Qin Lang didn't answer, he fought back as he walked, and the four of them retreated while running, but this situation didn't last long, and this small cave quickly ran to the end.

Outside the end, there is also a huge bluestone platform, like a huge square, surrounded by no obstruction, and what makes people feel even more desperate is that at the end of the bluestone platform, there is a lake.

This lake is supposed to be an underground lake in a cave, and the lake is turbulent, and it is impossible to see it at all when you look at it from a searchlight.

Listening to Luo Yingying and Zhou Mei's information, Qin Lang and Zhou Shaohua's faces were very heavy.

It seems that today, I am afraid that it is really their burial place, so the four of them glanced at each other and evacuated directly to the lake.

Listening to the piercing squeaks in front of them, the four of them made up their minds that they had really reached the last step, and would rather be drowned than be reduced to the rations of these mutant rats.

After a dense volley of bullets, the mutant rat swarm in front of him, red-eyed, slowly approached.

Just as the four of them were about to turn around and jump, suddenly, this group of mutant rats that were approaching step by step stopped at a distance of only ten meters from the four of them.

He screamed desperately at the four of them, but he didn't dare to take a step forward, as if there was some great danger in front of them.

Qin Lang and the four of them didn't have any excitement, holding guns and confronting the mutant rat in front of them.

After about ten minutes, the mutant rat tide let out a helpless roar, and finally slowly retreated.

Qin Lang and the four of them looked at this scene, their bodies did not move for a long time, as if they were in a state of flux, and after a while, after confirming that the mutant rat tide had really receded, they were unable to sit on the ground.

Zhou Shaohua's body trembled a little, and he said softly, "Mom, we are really favored by God and escaped a catastrophe, but you say, this group of mutant rats retreated, is there something in this lake that they are afraid of?" ”

"Shut up!"

Almost at the same time, Qin Lang, Luo Yingying, and Zhou Mei roared at Zhou Shaohua, and Zhou Shaohua suddenly fell silent.

After the toss just now, the four of them breathed a sigh of relief, turned around, and took a serious look at the rushing lake in front of them.

This underground lake is even bigger than the last time Qin Lang and Luo Yingying encountered it in the abandoned military dungeon.

Roughly speaking, it is at least three or four times the size, and can even be described as a river.

The water is not clear, it is turbid, and even at such a close distance, only the most superficial layer can be seen when hit by a strong spotlight.

The four of them were silent for a while, then got up, still determined to cross the river.

Although I don't know what is hidden in this underground river, but retreat, the group of mutant rats is waiting for them, go forward, even if there is great danger, they have to try.

The four of them opened a huge backpack behind them and stuffed it with pieces of metal.

These pieces of metal are nothing else, but a kind of improvised splicing bridge.

Although it is not as good as Xiangye them, there is no big problem in crossing the river for more than ten meters.

Although the backpack was load-bearing, Qin Lang insisted that he did not discard these things, and now they are useful.

This kind of metal sheet, in addition to being spliced into a bridge, can also be made into a simple boat, as long as it is fixed with a rope, it can carry a weight of 500 catties.

After more than half an hour of assembly and splicing, an iron boat two meters long and one meter wide was installed.

The four of them pushed hard, pushed the iron boat down the river, and got on the boat one after another, Qin Lang and Zhou Shaohua one after the other, manipulating the iron boat and protecting Luo Yingying and Zhou Mei in the middle.

Under the control of the two of them, the iron boat slowly headed towards the underground river ahead.

After getting off the river, Qin Lang really felt the light of the scope of this underground river, and they walked for half an hour, and there was still an endless river in front of them.

I don't know where this underground river leads, but as it goes deeper, the surrounding river becomes more and more turbulent, and the splashing water falls on the iron boat, making a crackling sound.

Qin Lang and Zhou Shaohua were manipulating the iron boat, becoming more and more difficult, and not long after the two of them tried their best to maintain it, a large number of bats flew down on their heads in an instant.

These bats are different from the outside, almost twice their size, with an outstretched wingspan of nearly two meters.

Attack at the four, bang!

After a burst of gunshots, large swaths of bats fell into the river and were swept away by the river.

Even so, it didn't scare away the group of mutant bats, they still attacked the four of them back and forth.

Although the four of them did not fall into the water, they had small wounds on their bodies, and blood dripped into the river.

The mutant bats slammed in waves, blood wrapped around the corpses, washed away by the river, and gradually, a smell of blood filled the air.

After striking down a wave of bats, the pitch-black river was gradually washed by blood, and Qin Lang suddenly understood his intentions.

These mutant bats are constantly harassing them, afraid to attract the attention of some creature at the bottom of the river.

For example, the great white shark, the overlord of the sea, can attract its attention as long as there is a little blood, but now in this underground river, blood has almost changed the color of the river.

The fact that the unknown creatures hiding at the bottom of the river are motionless can only mean that there are not enough.

What kind of monster is this, it is so terrifying, quite here, Qin Lang didn't dare to continue thinking about it.

shouted at Zhou Shaohua, "Huazi, don't entangle with these bats, get out of this water area quickly!" ”

Zhou Shaohua gritted his teeth and nodded, one after the other, using the strength of feeding, accelerating wildly, and Qin Lang and the two of them manipulated the iron boat to keep heading forward.

After passing a corner, in the river in front of the left, a forest of dead trees appeared.

Seeing this scene, Qin Lang was overjoyed in his heart, and he accelerated with his life, but in just a few minutes, the iron boat crashed headlong into the dead wood and vine forest.

Qin Lang took the lead, jumped down, and quickly pulled Luo Yingying, Zhou Mei, and Zhou Shaohua over.

The four of them stepped on the vine forest, while the group of mutant bats that frantically attacked the four people stopped, and then flew back.

The turbulent river carried blood in front of the four of them, as if forming a whirlpool.

Before Zhou Shaohua could speak, the next moment, Zhou Mei let out an exclamation, covered his mouth and said, "Hurry... Look, there's a corpse! ”

The three of them looked up in unison, and above them, a floating corpse slowly passed them and finally flowed towards the whirlpool.

The four of them looked at the corpse's face and froze for a moment.

"Hadron!"

This corpse is none other than Li Qiang, who fought with Qin Lang before and has the strongest combat effectiveness in the Defense Division.
