Fang Qi walked about five hundred steps inside, and the light around him became darker and darker, reaching the level where he couldn't see his five fingers, but fortunately, he wore a night vision device in advance, and his own eyesight was far beyond ordinary people, and the dark environment did not have a big impact on him.

It's just that the bad visibility in the cave is not only the low visibility, the further you go inside, the lower the oxygen content in the cave becomes, if a person with a large lung capacity walks to where he is now, he may have been dizzy due to lack of oxygen, and even shocked and comatose. In addition to the low visibility and lack of oxygen, the miasma in the cave is also becoming more and more poisonous, and the skin of his whole body has become sticky at this time, which is caused by the miasma eroding the skin.

And in addition to these, psychological suggestion is also an influence that cannot be ignored. Walking alone in an unknown dark cave, people will instinctively feel fear, loneliness, panic and other negative emotions, walking in such a claustrophobic and dark space, people who are not strong in their minds are very likely to go crazy.

What I said above can't have much impact on the other party, what I practice martial arts is to practice a layer of skin inside and outside, not to mention that his skin is invulnerable, at least it is also extremely resistant to blows, so the miasma is useless to him. As for the effect of mental action, it does not exist, if there is a lack of oxygen, he can use internal force to run the meridians around the body, reduce the body's consumption of oxygen, and can also cope with it.

While estimating his surroundings, he continued to walk forward, suddenly, goosebumps suddenly erupted all over his body, and the danger signal instantly surfaced in his mind to warn, when he looked ahead again, he was stunned to find that there were suddenly countless pairs of blood-red eyes above his head, and the scarlet light points were so striking and strange in the dark cave, after seeing clearly, he gasped - this is a group of bats that are extremely numerous.

In the next second, a shrill cry and flapping wings sounded, and the natives in the cave clearly did not welcome him as an uninvited guest.

Fang Qi felt the sudden acceleration of the flowing air, knowing that the bats were beginning to attack him, the internal force was running, the muscles were tense like springs, and the Miao knife on his back was instantly pulled out in a flash of his left hand, and the dagger in his right hand danced out of an impenetrable defensive circle in the area of half a meter around his body, killing all the bats that attacked him.

The bats here are very crazy, they are not afraid of death, and the number is unusually large, and ordinary people are almost dead when they face this bat swarm, even if they have modern firearms, it will not help. Only by thinking of such a way and cultivating martial arts to the point of perfection, and whose body is the strongest weapon, can it be possible to gain a glimmer of life in this desperate situation.

Two hours have passed, and there are countless bats that have died in Fang Qi's hands, but the number of bats has not decreased at all, and it is still the same as at the beginning, enclosing the entire space impenetrable.

During this period, Fang Qi also kept thinking about solutions. He thought about exiting the cave for a while and going outside to get some homemade torches to keep the bats away, but then he thought of the miasma that filled the cave, and he didn't know if the flames would ignite the miasma, after all, some flammable gases were easily produced in confined spaces. And he doesn't have much time, Donald doesn't know when he will return to the west, and the time limit does not allow him to retreat.

Until this moment, his martial arts talent was completely stimulated, and the Taijiquan, Bajiquan, Xingyi Quan and Tongbei Quan that he had practiced before were exerted to the extreme by him at this moment, using the knife as a fist, and every time he attacked, a bat must be split in half. He didn't sit still, fighting the bats as he walked deeper into the cave.

I don't know how long it has been since he killed, but his two arms have been waving non-stop, and there is only one thought in his mind, which is to kill, kill, kill. The further you went, the wider the cave became, and the temperature became higher and higher, until finally, a fiery red glow appeared in front of me.

Fang Qi suddenly felt a light in his hand, it turned out to be a knife slashed in the air, looking around, the originally dense bats had disappeared, and when he looked back, the ground was covered with the corpses of bats, and the blood flowed like a river, and the corpses were at least 20 centimeters high, covering most of the passage.

He breathed a sigh of relief in his heart, and sat on the ground, thinking about nothing, just thinking about quickly recovering his exhausted physical strength. At this time, he was already bloodstained all over his body, except for a pair of eyes that were clean, he couldn't find a clean place on his body, and killing so many bats also made his body inevitably bring a sense of anger, but fortunately, with the recovery of physical strength and the sobriety of consciousness, this anger also slowly faded.

"It's crazy, these bats are crazy. He muttered to himself, still feeling a little afraid. I don't know if these bats haven't drunk fresh blood for too long or what, they are very ferocious, and the end of the fierce and fearless death is simply a fight with zombies.

If it weren't for his amazing combat effectiveness, he really wouldn't have been able to get out of the bat swarm.

When fighting against the bat swarm, a thought flashed through him for a moment: "Why don't you be your richest man and enjoy the money you can't spend, but come to this place where birds don't poop and find an active substance that may not exist?"

This was the first time he had doubts about his decision, in the past, he had always been unusually firm in his decision, and the appearance of the bat swarm could shake his will, which showed the horror of this bat swarm. He thought about it, even if a group of 50 mercenaries encountered this group of bats, they might all be wiped out, this group of bats was really too fierce and crazy.

While reminiscing about the scene of the battle, he ate the dry food and water he had brought with him, and the sleepiness caused by the exhaustion of his physical strength slowly subsided, and his energy returned to his body. Only then did he have time to take a look at the environment in front of him.

He found it so hot, very hot, at least 45 degrees Celsius, and he felt sweaty after a while. When he looked ahead, he saw a scene that he would never forget.

The place where he sat was a T-shaped cliff, and below the cliff was an underground magma river that flowed slowly from left to right, and opposite, there was also a T-shaped cliff of about the same size, but the two were disconnected, and there was at least a hundred meters in between.

From him, he could see that the part below the cliff that touched the magma river had been burned red, and occasionally small pebbles fell down, and after a while, they turned into powder and became part of the magma river.

He swallowed hard, and despair began to appear in his heart. Although he has rough skin and thick flesh, he thinks that he is not thick enough to resist the temperature of magma, and once he falls into the magma river, he will definitely be burned to the point that there is no bone ballast left.

He didn't carry a rope on him, this situation was obviously something he didn't expect, in this dilemma, he decided to give it a go, the hesitation in his eyes turned into determination, he came here, how could he give up halfway.

His method is very simple, that is, with his own bouncing power, he jumps onto the opposite cliff and, yes, over the 100-meter-long fault zone.

This thought can no longer be described as crazy, it should be described as an idiot's dream, whimsical, and the stupidest method of suicide. Even the world's top long jumpers can't jump a distance of 100 meters, while ordinary people can jump to a distance of 2 meters is already very good. A hundred meters of long jumping, which is impossible for humans to do.
