"What's that? Eyedrop? Qi Lin's afterglow caught a glimpse of Cheng Yanqiu's movements, and asked with some curiosity.

"No, it's a special potion, taken orally and externally, that allows me to have the same ability to see in the dark as you do for a few hours." Cheng Yanqiu said that in the dark underground space, the light source is too conspicuous, and if the two of them grope forward with a flashlight, the ghost knows how many uninvited guests will be attracted.

"Dark Vision Elixir? And this good thing? Qi Lin subconsciously touched his eyes - to be honest, although the ability of dark vision, although it doesn't seem to be advanced, it can't directly enhance the combat ability, but whenever Qi Lin uses it, he will feel that it is too convenient to have such an ability.

"Well, it's still a prototype, and continuous use will cause serious damage to the eyes." Cheng Yanqiu said.

"I don't think there's any need to use it continuously, it's already doing damage right now." Qi Lin saw that Cheng Yanqiu's eyes began to become red and swollen, and tears continued to secrete.

"This potion...... It's a bit irritating, how can I say it...... It's like putting a bottle of chili water in your eyes...... Hiss...... After a while...... Hiss...... It's fine......" The effect of the medicine has begun to take effect, Cheng Yanqiu gritted his teeth, and kept gasping from between his teeth.

"Couldn't it be a masochist who invented this potion......," Qi Lin muttered, pepper dripping eyes, but really creative......

It took about five minutes for Cheng Yanqiu's symptoms to ease, he wiped the tears on his face, and then followed.

"By the way, do you have a map of this area? There seems to be a fork in the road. Qi Lin pointed straight ahead, and three branch tunnel openings appeared at the end of the tracks.

"The left side is a dead end, the middle and the right side lead to the same place, you can choose any one." Cheng Yanqiu said.

"Right." Qi Lin said thoughtlessly.

"According to psychological interpretation, people who like to choose the side route are not confident and have no sense of security about the surrounding environment." I don't know why, Cheng Yanqiu suddenly pulled this.

"It feels like a boring test that often exists on WeChat public accounts in the old days, and the person who does the test will find that the results seem to be very accurate, but if he looks at each answer, he will find that all the answers are ambiguous content, which can be applied to almost 99% of people." Qi Lin shrugged his shoulders, although he had been begging for a living abroad in his early years, but after the mercenary group was disbanded, he also stayed in China for a while, and he still had some understanding of WeChat, the national social software in China.

"But I don't think this sentence is wrong, you must be a cautious and cautious guy, your subconscious makes you choose the fork in the road to the side, you must be always wary of things around you, and maintain a defensive posture at all times - how about it, I'm not wrong, right?"

"No, you're wrong, I said on the right, it's because there's blood at the mouth of the middle tunnel."

"Bloodstains?" Cheng Yanqiu was a little stunned, in his field of vision, he could only vaguely see three forks in the road, and as for the subtle things, he had to get close to see them clearly.

"Obviously, your pepper water with very side effects doesn't work as well as my passive skills." Qi Lin teased.

"What kind of bloodstains?" Cheng Yanqiu opened the safety of the submachine gun and asked in a low voice.

"Dried bloodstains, but in this environment, if it was a bloodstain from a long time ago, I would definitely not be able to see it now, and I can still see it, which means that this bloodstain was left in the recent past."

"It's better to be careful...... Since there is blood here, it is likely that something has classified this area into its hunting grounds, and in the underworld, creatures are more territorial than on the surface. Cheng Yanqiu said solemnly.

"yes, I know."

Cheng Yanqiu was holding a submachine gun, Qi Lin was carrying a steel pipe, and the two quickly and silently approached to the fork in the road.

It was indeed a pool of blood, the black viscous liquid had completely dried and solidified, and it was covered with fine cracks.

"Let's go." Qi Lin checked the steel pipe in his hand and walked into the tunnel on the right first, followed by Cheng Yanqiu.

The two of them advanced for nearly a hundred meters, and finally saw a living creature other than insects and bloodthirsty rats - it was a thin humanoid creature, clinging to the top of the tunnel, as if waiting for an ambush opportunity, but Qi Lin was the first to discover it, and immediately threw the steel pipe in his hand, and the tip of the steel pipe that was twisted into a twisted shape was very sharp, easily penetrating the ribs of the creature, and the creature immediately let out a terrible and sharp scream and fell from the top of the tunnel.

But it wasn't dead yet, struggling to get up from the ground, trying to escape as fast as it could into the depths of the tunnel.

It's just that Qi Lin didn't give it this chance, and quickly stepped forward and stepped on its ankle, and then neatly twisted the other party's neck.

"This seems to be a person...... Cheng Yanqiu walked up and looked at the monster's corpse.

"It used to be a man."

There is almost no difference between this monster and a human, and its scrawny body looks like a long-term hungry and white-skinned man, which is caused by not being able to contact the light for a long time.

The limbs are slender, the long nails are sharp and hard, stuffed with all kinds of filth, and the eyeballs are atrophied due to degeneration, but the teeth are unusually developed, especially the two sharp canine teeth, which are several times longer than normal humans, and are exposed to the outside of the lips.

The monster had no hair on its body, blue-black blood vessels could be clearly seen under its pale skin, and the organs in its crotch that symbolized the identity of the man had degraded to a negligible level.

Qi Lin suddenly felt that this guy was almost exactly the same as the monster that the protagonist encountered in an underground cave in a movie called "Dark Invasion" in the old days.

But then again, the original monster, that is, a humanoid that has adapted to underground life, and the creature that has just been killed by Qi Lin is highly consistent in terms of background and environment.

They used to be human, but now they can't be called human.

"Do you think this creature is solitary or in groups?" Qi Lin suddenly remembered that in "Dark Invasion", there was more than one humanoid monster like that, and there were almost everywhere in that cave!

"I don't know...... But I still hope it's a lone ranger. Cheng Yanqiu swallowed a mouthful of saliva and said. ()
