"Damn."

Guo Zhenyu did not even know what the thing that attacked him was!

And these things had hurt him.

Normally, the thing that had assaulted him earlier would not have succeeded if his vision hadn't been affected.

However, this was not the time to be thinking about such things. Guo Zhenyu raised his hand and shot at the dense swarm of bats. Although he killed many bats with his bullets, it was but a hair on the head for these bats.

"F * ck."

Guo Zhenyu finished shooting all the bullets in the shotgun and found that there were still so many bats.

It was a pity that he was inside the cave. If he had used explosives, he would have been able to quickly get rid of these irritating fellows. However, he would also be the one to be buried along with them.

"System, is there any solution?"

Guo Zhenyu threw the empty shotgun to the ground, then took out a shotgun from his space pocket.

"You can use the flamethrower to attack it. In addition, the host's intelligence is urgently needed."

The system made Guo Zhenyu so angry that he almost vomited blood.

"Exchange."

Guo Zhenyu ordered the system snappily.

In an instant, Guo Zhenyu had a backpack that provided fuel for the flamethrower. In his hand was a flamethrower.

Guo Zhenyu pulled the trigger, a thick fire snake spouted out of the barrel muzzle, instantly lighting up the cold and damp cave. Under the light of the fire, Guo Zhenyu was finally able to see everything clearly.

As it turned out, there was not only one path to this cave. Guo Zhenyu had been using his glowing stick to explore the way, so he subconsciously thought there was only one. Unexpectedly, this cave had many paths leading in all directions.

It was unknown how many there were in this group of bats. Even if there were over 10,000 bats, it was only Guo Zhenyu's rough estimate. After all, Guo Zhenyu did not have the patience to count so many things one by one.

Besides, there was the stench of bat dung in the air, making people want to puke even for a second longer, not to mention counting the number of bats they had to be so patient with.

A fire lit up in all directions. The entire cave was immediately filled with the smell of barbecue, along with the thick smell of bat dung and the musty smell of the cave. When these smells were combined together, it made people feel dizzy and dizzy, Guo Zhenyu probably wouldn't be able to eat for two to three days.

Due to the continuous spurting of flames, the flame thrower's nozzle had started to heat up. However, this group of bloodthirsty bats were still risking their lives as they charged towards Guo Zhenyu one after the other.

Guo Zhenyu really had no other choice. He finally chose to use his magic treasure, exchanging it for a custom-made napalm bomb from the system, and with one hand holding the flamethrower, he used the other to throw the gas bomb, which was only the size of a forearm, into the group of bats. Then, he fired a few more shots at the direction of the incendiary bomb, causing the bomb to explode in the air as Guo Zhenyu quickly dodged to the side of the path.

"Rumble."

The explosion made Guo Zhenyu's ears go numb, and he could only feel a buzzing in his head.

No matter how cunning and fierce the animals were, they still felt an instinctive fear when faced with the raging flames. Before, Guo Zhenyu was unable to completely expel these bats because the flame ejected from the flamethrower in his hand was on a completely different level from the bats that blotted out the sky.

After taking care of the bats that were luckily flying over, Guo Zhenyu continued to move forward.

After walking for about half an hour, the sound of flowing water gradually appeared on the right side of the road. This place had a hidden river, but Guo Zhenyu could not hear the sound clearly.

However, right now, Guo Zhenyu was not interested in this secret box, he was just trying to figure out what kind of creature attacked him just now, to have such a powerful ability. Although Guo Zhenyu was in the darkness at the moment, his line of sight was not clear, but facing an opponent, he had already been chopped into mincemeat! But that thing was elusive.

Just a moment ago, he had only ambushed Guo Zhenyu and injured his shoulder before running off to an unknown place.

This caused Guo Zhenyu to be on guard against him at all times. What if that thing ran out again and hurt him?

The sound of flowing water could be heard from afar, making Guo Zhenyu's ears almost lose all sense of what was happening inside the cave.

Guo Zhenyu's ears were now filled with the sound of flowing water, causing him to almost hallucinate.

The cave was connected in all directions. If the system had not given him directions, Guo Zhenyu could not be sure that he would just get lost in this complicated underground karst cave.

The direction he was heading in was downhill from time to time, and as he walked further, the temperature around him dropped significantly. He could hear the sounds of underground creatures from time to time, but now, only the hidden box was left to accompany him.

"We still have a hundred meters before we reach our destination. Host, please be careful of the surrounding defenses."

The system prompted.

After Guo Zhenyu heard the system's notification, he was also extremely alert. After all, he had already reached this stage. He really could not tolerate any negligence.

Guo Zhenyu exchanged for another glowing stick and threw them all around him. With the help of the night vision goggles he wore, he was finally able to see the appearance of this place clearly.

It turned out that after several hours of hard travel, Guo Zhenyu had finally reached his destination.

Compared to the spacious area, the path they were on earlier was like a small, narrow pathway.

This alien ruins looked indeed majestic.

At this time, Guo Zhenyu had already arrived at the deepest part of the karst cave. Not only was there the sound of running water, but also the sound of the wind.

However, Guo Zhenyu had no way of knowing where the whistling wind came from.

With the help of his night vision goggles, Guo Zhenyu arrived at the interior of the alien's ruins.

"Pata."

Guo Zhenyu only used his hand to touch the alloy door, the entire relic let out a buzzing sound.

A soft, milky white halo of light shone from the ruins, illuminating the entire cave in an instant.

Guo Zhenyu was blinded by the sudden light and quickly took off his night vision goggles. Borrowing the light from the ruins, he looked at his surroundings.

It turned out that this so-called relic was a UFO that no one had used for many years.
