After resting for a while, Luo Yingying and the three were woken up by Qin Lang, and the three of them looked at the scene in front of them, all of them were a little stunned.

"Lao Qin, what's wrong with us, what's going on?" Zhou Shaohua shook his head and asked.

Qin Lang pondered for a while, and then said, "I think we are afraid that we are hallucinating because of heat stroke caused by the high temperature." ”

"My obedient, so evil, I was hallucinating unconsciously, fortunately Lao Qin, you woke up in time, otherwise it would probably be cold." Zhou Shaohua sighed with fear on his face.

Qin Lang shook his head and said softly, "No, it wasn't me who saved us, but Xiaolong." ”

Zhou Shaohua was stunned for a moment, looking at the yellowing whistle in Qin Lang's hand, and just wanted to open his mouth to comfort Qin Lang, but was interrupted by Qin Lang.

"Huazi, don't say it, I know what you want to say, some things have to be put down, you have to move on, I can't let Xiaolong down."

Qin Lang said very softly, but there was a strong firmness in his voice, Zhou Shaohua stared at Qin Lang who was slowly getting up, and he suddenly found that the decadent aura hidden in Qin Lang's body dissipated in an instant.

Qin Lang, who made everyone admire and acted resolutely and decisively, is back.

Zhou Shaohua's face was full of joy, and he hurriedly got up and said, "Since we are safe and sound, let's find an exit as soon as possible and rush to Heidushan as soon as possible." ”

Qin Lang shook his head and smiled at Zhou Shaohua, "Huazi, I don't think I need to find any exit, I'm afraid we are in Heidu Mountain now." ”

"What? This... Lao Qin, I'm confused. ”

Don't say that Zhou Shaohua is confused, Qin Lang, Luo Yingying, and Zhou Mei may not be able to figure it out.

At first, Luo Yingying also didn't believe it, the four of them were in Heidushan, but when they saw the micro-device in their hands showing an undulating line, they could most of them be sure that the location was Heidushan.

Only Heidushan can have such a powerful magnetic field, not only the equipment it carries cannot be used, but even the most primitive compass is violently shaking.

What is inside Heidu Mountain, they don't know, the magnetic field is so strong, several times beyond the outside world, it is difficult to say, in the darkness ahead, there will be no monsters like mutant rats.

After the four of them rested a little, Qin Lang and Zhou Shaohua took the lead, and the two of them held automatic rifles and bazookas respectively, and slowly advanced under the searchlight of Zhou Mei and Luo Yingying.

"Lao Qin, did you say that in front of this, will you encounter the group of dead rats just now?"

Qin Lang didn't say anything, and the three of them threw Zhou Shaohua a roll of the eye almost at the same time.

Zhou Shaohua hurriedly covered his mouth and smiled awkwardly.

The four of them walked forward in pairs, and after the light source, they seemed to be in a karst cave, and the walls around them were dry, and they looked natural.

But what seems a little incompatible with this natural karst cave is the bluestone under the feet of the four people.

I thought that bluestone was just a large piece of natural stone that was raised, but who would have thought that this bluestone had been spreading to the end of the line of sight, and I didn't know how long it was.

As they observed more and more, the four of them felt more and more that this bluestone stretching at the end was like an artificial carving.

In this kind of natural karst cave, there are traces of artificial carving, which is very abnormal, especially Heidushan, which has been banned for seven or eight years.

The four of them walked slowly, their hearts tense, and there was an urge to get stuck in their throats.

"Click!"

In the quiet of the cave, there was a sudden sound that sounded like some kind of mechanism activating.

The four of them hurriedly turned around, and quickly found the source of the sound, and at Zhou Shaohua's feet, a gap suddenly appeared in the very smooth and flat bluestone.

"Zhou Shaohua, what are you doing!" Zhou Mei, who has always laughed and groaned, rarely spoke out.

Zhou Shaohua felt embarrassed and hurriedly explained, "Mei'er, listen to my explanation, I didn't mean it, it shouldn't be so coincidental, it's nothing..."

"Huazi, wait, don't talk, there's movement."

Zhou Shaohua still wanted to explain, but was suddenly interrupted by Qin Lang, and the four of them hurriedly listened.

"Squeak, squeak..."

In the silent passage, some harsh sounds, coming from the darkness behind, were small at first, but soon covered the entire cavern.

The searchlight swept away, and the four of them were shocked, "Wo Ri, Lao Qin, this is a rat's nest." ”

"Huazi, you're a fart, run!"

Qin Lang roared, and in an instant, the four of them ran towards the front frantically.

Behind, the mutant rats that cannot be described in numbers are like waves of the ocean, rapidly impacting.

"Da-da-da, da-da-da..."

"Boom! Rumble! ”

Inside the cave, the dense sound of bullets was accompanied by the sound of explosions from time to time.

The ground shook, the dense gravel fell overhead, and in the darkness, the firelight swayed, but the pitch-black wave of mutant rats behind instantly extinguished the firelight and surged.

"Lao Qin, if you have to find a way, there are too many mutant rats, and if this continues, we all have to become the rations of these rat cubs."

"I know, Huazi, run separately, buy time for Yingying and Zhou Mei, and find a chance to do it again!"

The four of them quickly had a countermeasure, Qin Lang and Zhou Shaohua scattered on both sides and shot alternately, while Luo Yingying and Zhou Mei arranged explosives on the stalactites on the top of the towering cave in the rear.

Bazookas and bullets are fired alternately, although the power is very strong, but in the face of the dense rat tide, this damage is insignificant.

In just a few minutes, Qin Lang and Zhou Shaohua had to retreat.

"Dr. Luo, okay, I can't hold it anymore."

Zhou Shaohua was excited in his heart, holding a rocket, and fired another shot at the rat tide in front of him, and his face was a little colorful.

Brilliant firelight accompanied by a wave of diffuse air rose into the sky, and the rubble above the cave kept falling.

fell into the rat tide and was quickly extinguished again, for this scene, Zhou Shaohua didn't even look at it, a rocket bombarded it, and he had already evacuated in time.

"Huazi, withdraw quickly, it's okay!" Qin Lang shouted at Zhou Shaohua in front of him, and at the same time shot to cover Zhou Shaohua.

"Rats, Master Zhou is giving you a brilliant fireworks."

A rocket was launched, and Zhou Shaohua quickly came to Qin Lang's side with a slippery flat shovel.

The four of them stood in front of a branching karst cave, the bluestone thirty meters in front of them had long been covered by the rat tide, and the dense stalactites above were hanging high in the air.

As the rat tide approached, the four of them had cold faces, and they were all silently counting the seconds.

"Three, two, one!"

"Boom! Rumble! ”

As the timed explosives on the stalactites ran out, a huge explosion sounded instantly.

Countless stalactites fell in response, and a powerful shock wave accompanied by a violent explosion resounded through the cave.

The momentum was so strong that they smashed the bluestone under their feet into a big hole, and countless mutant rats fell into the black hole below.

Looking at this scene, Zhou Shaohua laughed even more, "Haha, rat cubs, tell you to chase Zhou Ye, come, Zhou Ye is waiting for you here." ”

Zhou Shaohua shouted excitedly, but this happiness did not last long, and the smugness on Zhou Shaohua's face froze instantly.

The huge black hole smashed by countless stalactites was actually filled by the rat tide behind and built into a rat bridge.

A large number of mutant rats in the rear attacked the four of them again through the rat bridge.

"Damn, I don't play like this."

"Zhou Shaohua, close your crow's mouth," don't run yet. Luo Yingying, who has always been good-tempered, said indignantly.
