Ding Xiu rushed in the direction of the first team's search, and saw two or three people from a distance surrounding a stone wall with panicked expressions.

"What happened?" Ding Xiu hurried over and asked.

"Brother Xiong had an accident when he entered the cave." One of them pointed to the stone wall, and Ding Xiu followed the direction he was pointing to see a hole the size of a basin.

This hole was relatively hidden, and the weeds were overgrown next to it, and the multi-functional combat power detector on Ding Xiu's ears vibrated again, and this time the frequency of the vibration was even more rapid than the previous one.

"D-class mutant flying foxes spotted."

"Discover the C-class mutant Foxgat King."

"C-grade?!" Hearing the warning in the device, Ding Xiu was shocked, knowing that Li Xiong should be more auspicious.

"You're all waiting outside, I'll go in and take a look." He admonished the people around him.

"Are you going to go in alone?" The companion behind him asked.

"If you're not afraid of death, you can follow, but I'm not sure you'll be able to protect you." Ding Xiu's gaze was as serious as his tone, full of warning.

"Zhang Ming, don't go with you, Brother Xiong, they ......" The people in Li Xiong's team who stayed at the entrance of the cave also persuaded.

Everyone stayed outside the cave, Ding Xiu had already climbed to the entrance of the cave, he looked inside, except for the light near the entrance of the cave, it was completely dark a little farther inside.

A gust of wind came from the cave, and there was a smell of fishy and damp smell in the wind, as well as a slight smell of blood.

Judging from the flow of air in the cave, Ding Xiu guessed that the space inside would be very large, and the entrance to the outside would not be the only one in front of him.

He thought about it and got into it anyway.

The light began to dim, and Ding Xiu pressed a switch on the multi-functional combat power detector to turn on the device's night vision function.

After the infrared rays emitted by the multi-functional combat probe hit the target, they will be reflected back and re-received by the equipment to form an image, making the dark environment in the cave clearly visible at once.

The equipment made by Chen Jianing for Ding Xiu uses the algebra of the image enhancement tube beyond the standard of ordinary military, which allows Ding Xiu to see more realistically and farther in the dark environment.

The further you go into the cave, the more spacious it becomes, the rocks inside are craggy, and the ground is also very rugged. Ding Xiucai walked into a distance of more than ten meters, and saw huge figures falling from the top of the cave, and those figures were imaged in the night vision device with two small glowing dots.

Those figures are mutated foxes, and the glowing dots are their eyes!

Sensing the presence of foreign intruders, the flying foxes hanging upside down flapped their wings and circled on the top of the cave, threatening to dive and attack.

Feeling threatened, Ding Xiu naturally wouldn't let the enemy make the first move, he had already held the hand of Yanlong in his hand, his eyes scanned the surroundings, and he didn't find Li Xiong and the other members of the cave team.

"Whew~" The first flying fox began to attack, and it roared down with the sound of the wind, and went straight to Ding Xiu's front door.

Ding Xiu raised his hand and shot it, shattering its body into two pieces in the air.

The sound of gunfire echoed through the hole, and the fluttering of wings became louder.

"That's a lot!" Ding Xiu killed several flying foxes that wanted to pounce on him, but when he looked up, it was like a black cloud covering his head, and the black pressure was all their companions.

More and more mutant flying foxes began to attack Ding Xiu, Ding Xiu's movements were fast, but his personal firepower could not cover the entire offensive surface.

As the gunshots exploded like popping beans, more and more flying fox carcasses landed around. Ding Xiu's feet were already scattered with bullet casings, but the number of enemies did not decrease in the slightest.

"I can't do it!" Ding Xiu knew that he couldn't defeat the large number of flying foxes in the cave on his own, but he still didn't want to retreat, because he hadn't found Li Xiong and the others yet.

Ding Xiu tried to advance deeper into the cave, but waves of flying foxes blocked his progress, and if it weren't for the increase in the power of the war paint, I am afraid that he would be scarred by now.

The mutant flying fox's attack is very simple and straightforward, it is to swoop down from the air and pounce on the vital point of the person, either tearing off a piece of flesh or leaving a claw mark.

Ding Xiu dodged and counterattacked, and suddenly he noticed that the fox bat crowd had a few larger figures.

"Is it D-class and C-class?" He was shocked, knowing that a more advanced mutated creature meant even greater danger.

"Gotta withdraw!" Ding Xiu had clearly realized that going deep into the cave was beyond his ability, and he had to give up his plans to go further, after all, there were more and more enemies, but his bullets and room to dodge were getting less and less.

Just as Ding Xiu was about to retreat to the entrance of the cave, a part of the flying fox group bypassed and blocked his retreat.

This time, all sides were surrounded by flying foxes, and Ding Xiu's field of vision was full of black and oppressive flying fox swarms except for the ground under his feet.

These mutated flying foxes have a wide wingspan, and although they are in a hole, they can give the illusion of obscuring the sky when they fly in groups. And although these flying foxes are huge and their flight paths seem to be chaotic, none of them have collided with other companions.

"This is a problem." Ding Xiu saw that the back road was blocked, and he didn't carry grenades or large-caliber weapons suitable for opening the way, so it would be difficult to fight his way out by relying only on the hand of Yan Long.

The mutant flying fox's posture was slightly bulkier than that of ordinary small bats, but relying on their numerical superiority, they quickly formed an absolute suppressive force when facing Ding Xiu.

Ding Xiu's bullets were not missing, but his individual strength still seemed very small in front of the group. If the number of flying foxes in the cave did not exceed a hundred, then he might be able to defeat his opponent, but now the number of flying foxes is far more than a hundred, and this is not a strength that Ding Xiu can match.

A big flying fox almost succeeded in a sneak attack while Ding Xiu had no time to take care of the gap behind him, Ding Xiu heard the whirring wind behind him, and the military spur in his left hand had already come first, piercing the flying fox.

A dozen pounds of flying foxes were strung on the military thorns, its wings and claws were still fluttering, and Ding Xiu flicked his wrist and threw it out.

At this time, the tongue of fire that spewed out in Yan Long's hand suddenly extinguished, and Ding Xiu had already used up the last bullet, so in desperation, he had to hold the handle of the gun and slash.

The blade of the spear split one after another of the flying foxes that pounced on them, but the successors seemed endless, and Ding Xiu's head was sweating.

The ball in his pocket seemed to sense that something was wrong, it was a little restless at first, and Ding Xiu didn't notice its abnormality because he was concentrating on the battle.

An overclocked radio wave radiated around the cave from Ding Xiu's pocket, Ding Xiu couldn't feel this biological electric wave, but the flying foxes that were coming at him were confused for a moment. They suddenly became panicked, and some of them bumped into each other in flight.
