Everyone searched around the vicinity of the East Vice-Entrance and found nothing except for the remains of a few monsters that had been crushed. The corpses of these monsters had already been crushed into a puddle by the unknown force, and they couldn't see their original appearance at all. However, the graves of the five warriors remained in good condition and were not destroyed.

No anomalies were found, and everyone had to rest on the spot, and all of them entered the car when they were ready to sleep. After all, the night in the wilderness is very cold, and it will be warmer when six people gather. So early the next morning, after everyone checked their equipment and supplies again. Entered the half-collapsed cavern.

At this time, the cavern may have collapsed, and the original effect of covering almost all visible light sources was gone, and the bright lights on the equipment illuminated everything around them. The part of the cavern that has just been entered is earthy yellow, while the other part is a purple-black substance that seems to have been left behind after the mass death of some living beings. After seeing the substances, Onno crouched down and examined them carefully, and determined the source of the substances.

These purple-black substances are a kind of "blanket" made by the biological weapons of human enemies that can corrupt the ground, and the corrupted ground is very similar to the radiation left over after the use of nuclear weapons by humans, and it will cause some biological mutations. However, now, the purple-black blanket has completely lost its vitality and has become part of the ground.

When everyone heard that this thing had lost its vitality, they were relieved. However, they were still careful to step on the earthy yellow ground, in case anything unusual happened. It's just that the earthy yellow apprentices on the ground are becoming fewer and fewer, and the purple-black blanket is gradually occupying the entire ground. At this time, everyone had gradually walked to the place where Onno was fighting with those spider octopus monsters, and there were still the corpses of those monsters on the ground, and half of the body of the largest monster had been completely shattered, leaving only a general gray-white body and countless godless eyes.

The crowd was still apprehensive when they saw the monster, but they were relieved when they were equipped to make sure that the thing was completely stoned. And when everyone looked up at the roof of the cave, they found that there were still a lot of pale red carapace on the roof of the cave, but almost all of these carapaces were broken, presumably because of the last battle between Onno and the group of guys.

Continuing to move inward, everyone finally came to the place where it was full of monster eggs, except for those dead eggs on the ground that could emit a strange blue light, all the other eggs had been broken and hatched, but these little monsters were all killed by Onno's pot of stew. When Ono saw the remains of these eggs, he ordered everyone to take out their weapons, because it was not far from the real entrance to this base!

As he spoke, he led the group deeper and gradually came to the vicinity of the huge cave where the expedition team had arrived. Looking inward from this opening, you can see two huge directions leading to the left and right. Through the detection of the equipment on the people's bodies, the passage on their right side has been completely sealed, and the one on the left can lead to the depths unimpeded.

"Let's go!" At Onno's command, everyone entered the long corridor with their weapons in hand. In this corridor, it is not completely dark, but there is a kind of biological cold light that shines and illuminates the entire passage in a dim state. The light in the hands of Onno and the others pierced through the thick darkness and found something that emitted the cold light of the creatures.

It was a very strange-looking flying insect, with a huge head that seemed to be a bright light bulb, but the light was very low at this time, and the abdomen of these flying insects had completely merged with the pain. And this proves that in this cavern, the enemy's base may have entered a state of low energy.

It's just that Ono and the others don't know what else is active in this base under the condition of low energy, and even what has been mutated. Everything that Ono knew about this place was an unupdated version, and he naturally didn't know that there was such a base in this place.

"Ugh! Yikes! When the group was about to leave the passage, they suddenly heard the sound of water not far away, accompanied by a very rhythmic beating sound. When they heard the sound, they immediately became alert and loaded their weapons, and then walked towards the place where the sound was made.

Leaving the passage, after everyone turned a corner, the sound of water was even more obvious, just in front of everyone at the right turn. At this time, the crowd noticed that the purple-black blanket under their feet had disappeared and was replaced by an even more strange material, unusually hard and smooth to step on. According to Onno, the material is actually made from the bones of that kind of biological weapon.

When the corner arrived, the sound became more and more obvious, and when everyone turned the corner, they found nothing, only to see some yellow liquid seeping out of the wall, and a very strange board blocked in front of these yellow liquids, making a clicking sound. And on top of this board, Onno saw the familiar text, the special text "Cover Plate" on the Cosmic Watchtower! Ono was stunned when he saw this text, he didn't expect that someone had actually come in here, but he didn't expect that it was actually the personnel of the Cosmic Watchtower who had come in.

After examining the water coming out of the walls, they found that it was actually some water, mixed with the debris of some creatures, which caused the water to take on a yellow color. And when they walked around the walls and followed the water stains to a hall, they found that it was almost submerged in the yellow water, and everything in it was soaked in the yellow water. And there are two black shadows in this and yellow liquid, but these two shadows are entangled in everything, and the original appearance cannot be seen at all.

Ono and the others looked at this thing, and the detector did not find anything of value, so they continued to move forward. According to the information on his equipment, Onno led everyone to this labyrinthine place. The architectural style of these enemies is very uniform, which means that Onno can walk around the base with a map that is old without worrying about any problems.

It's just that what they don't know is that while they are walking, countless pairs of eyes have quietly opened on the wall and are staring at Onno and the others, and they are also relying on their natural stealth advantage to follow the six people, although none of the six people are aware, but there is always a sense of being observed in the dark. But Oon Nuo didn't say anything, and they didn't pay much attention.

Along the way, Onno discovers a number of equipment or devices related to the Cosmic Watchtower, but these devices and devices have been rendered useless, and some of the machines have some yellow-brown traces and some blood stains. The mix of these things is unusually weird. And this strange feeling became the largest when everyone walked into a cave where the entire cavern was made of a slimy black substance.

This black, slimy substance is still sticky after countless years, and people walk on it and make a comical "snapping" sound. At the same time, at the top of the cave, Onno and the others also found some strange carvings and white water droplets that dripped from time to time.

The strange sound of "gurg" sounded, and Onno and the others were alerted, and a large number of biological origins suddenly appeared on the life detectors they were equipped and were approaching everyone. People still can't see the traces of these monsters with the naked eye, and they can't even see the existence of these monsters with infrared vision. When Onno switched to electrostatic detection of silicon-based creatures, he found that they had just entered a trap!

Now everywhere on all sides of them is a monster that can only be sensed by static detection! The appearance of these monsters is a dark green in the pale green of static detection, the huge head has one eye, and the body covered with bones makes this monster look like it is made of simple skeletons, and the slender six limbs and two long tails are also covered with very sharp-looking barbs!

"Be careful, we're already surrounded, adjust your weapons to high heat, close your own hearing, and I'll share what I can see here! And then fire freely! At the command of Onno, the warriors all switched their weapons to high heat mode and immediately saw the picture that Onno could see, a large number of six-legged monsters were clinging to the wall or the top of the cave, slowly crawling towards everyone.

"Fire!" As soon as Onno gave the order, the weapons in everyone's hands fired, and the light blue plasma fireball instantly appeared and flew towards the monsters. And these monsters are unusually agile, even a little faster than the nerves of the warriors! After dodging the first wave of attacks from the warriors, the monsters also started their own attacks, spitting out thick phlegm at everyone!

And Ono released his protective shield in time to protect everyone! The thick phlegm was intercepted by the shield and fell to the ground, corroding the black, slimy substance clean. Later, Onno shared the auxiliary locking system on his equipment with everyone. In an instant, a very accurate trajectory prediction appeared in the field of vision of the warriors! The plasma fireball has also begun to harvest these strange creatures effectively.

These monsters move incredibly fast, and can spew out that corrosive thick phlegm almost infinitely! And after these monsters are killed, if the corpses are not disposed of in time, they will explode, and the hard bone fragments and strong alkaline blood will fly in all directions!

The number of these monsters is also unusually large, and after dozens of minutes of continuous firing by Onno and others, the number of these monsters has not decreased, and there is even a faint increase. Onno looked at the number of these monsters and knew that if he continued to fight here, he would be consumed alive. Hurry up and call everyone back to the place where they entered!

With the help of Ono equipment, the group fought and retreated to the passage they had entered this place, and Ono made everyone stand behind him, and he made a low body to prepare to swing his fist, a vortex with strong suction power was generated on Ono Nuo's fist, and over time, the space around this vortex gradually turned a dark red! When this dark red space appeared, everyone smelled a very strange smell in their noses that could be called "death".

"Drink!" Onno roared, and punched hard into the inside of the cave, the vortex slowly flew forward and began to devour the black slimy substance inside the cave, as it swallowed, the volume of the vortex gradually increased, and the speed of rotation became faster, and the speed became faster. At the same time, all the monsters that had been swept by the dark red spatial distortion had fallen off the walls or from the roof of the cave, and had stopped moving after a few struggles......
