"What is that? Eye drops?" Qi Lin's afterglow caught Cheng Yanqiu's movements and asked curiously.

"No, it's a special medicine. Oral and external use can allow me to have the ability to see things in the dark like you within a few hours." Cheng Yanqiu said. In the dark underground space, the light source is too conspicuous. If the two of them were fumbled forward on flashlights, they would know how many uninvited guests would attract.

"Dark Vision Potion? And this good thing?" Qi Lin subconsciously touched his eyes - to be honest, although the ability of Dark Vision seems not to be advanced and cannot directly enhance his combat ability, whenever Qi Lin uses it, he feels that it is too convenient to have such a ability.

"Well, but it's still a trial product. Continuous use will cause serious damage to the eyes." Cheng Yanqiu said.

"I don't think there is any need to use it continuously. Just now, it has caused damage." Qi Lin saw that Cheng Yanqiu's eyes began to turn red and swollen, and tears continued to secrete.

"This potion... is a bit irritating. How can I say it... it's like dropping a bottle of pepper water into my eyes... Hiss... After a while... Hiss... It's all right..." The effect of the medicine has begun to work. Cheng Yanqiu gritted his teeth and kept sucking cold air from the gaps of his teeth.

"Why wouldn't the one who invented this medicine be a masochist..." Qi Lin muttered, the pepper dripping eyes were so creative...

It took about five minutes before Cheng Yanqiu's symptoms were relieved. He wiped the tears from his face and followed him.

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

"There is a dead end on the left, and the middle and right lead to the same place. You can choose any one." Cheng Yanqiu said.

"To the right." Qi Lin said in confusion.

"According to psychological interpretation, people who like to choose the sidelines are all people who are not confident and have no sense of security in the environment around them." For some reason, Cheng Yanqiu suddenly started this.

"It feels like the boring tests that often occur on WeChat public accounts in the old era. People who have finished the test will find that the results seem accurate. However, if he read each answer, he will find that all the answers are ambiguous content, which can be applied to almost 99% of people." Qi Lin shrugged. Although he had been making a living abroad in his early years, he also stayed in China for a while after the disbandment of the mercenary group. He still has some understanding of WeChat, the national social software in China.

"But I think this sentence is right. You must be a cautious guy. The subconscious mind makes you choose the fork road that you lean on. You must be on guard against things around you and maintain a defensive posture at any time - how about it, I'm right?"

"No, you were wrong. I said I chose the right side, because there was blood at the entrance of the tunnel in the middle."

"Bloody?" Cheng Yanqiu was a little stunned. In his vision, he could only vaguely see three forks of roads. As for the subtle things, they had to get close to them to see clearly.

"Obviously, your chili water with extremely strong side effects is not as useful as my passive skills." Qi Lin joked.

"What kind of blood is it?" Cheng Yanqiu opened the security of the submachine gun and asked in a low voice.

"Dried blood, but in this environment, if it were blood from a long time ago, I would definitely not be able to see it now. I can still see it, which means that the blood was left behind recently."

"It's better to be careful... Since there is blood here, it means that something may have placed this area into its hunting ground. In the underground world, the territorial consciousness of creatures is stronger than on the surface." Cheng Yanqiu said seriously.

"Yeah, I know."

Cheng Yanqiu was carrying a submachine gun and Qi Lin was carrying a steel pipe. The two of them quickly and silently approached the fork in the road.

It was indeed a pool of blood. The black viscous liquid had been completely air-dried and solidified, and was covered with fine cracks.

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

The two of them advanced nearly a hundred meters and finally saw a living creature besides insects and bloodthirsty rats - a thin humanoid creature, climbing on the top of the tunnel, as if waiting for an ambush opportunity. However, Qi Lin discovered it first and immediately threw the steel pipe in his hand out. The tip of the steel pipe twisted into a twisted shape was very sharp and easily penetrated the creature's chest ribs. The creature immediately let out a shrill and sharp scream and fell from the top of the tunnel.

But it was not dead yet, and struggled to get up from the ground and quickly tried to escape to the depths of the tunnel.

However, Qi Lin did not give it this opportunity. He quickly stepped forward and stepped on its ankle, and then neatly twisted the other party's neck.

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

“It used to be a person.”

This monster is almost not very different from humans. Its skinny body is obviously hungry for a long time and has a slight skin. This is because it cannot get in contact with light for a long time.

The limbs are slender, the long fingernails are sharp and hard, and are filled with all kinds of dirty things. The eyeballs shrink due to degeneration, but the teeth are extremely developed, especially the two sharp canine teeth, which are several times longer than that of normal humans and are exposed to the outside of the lips.

There was no hair on the monster's body, and the blue-black blood vessels could be clearly seen under the pale skin. The organ between the crotch symbolized the male identity had degenerated to a negligible level.

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

But then again, that kind of monster, which was originally a humanoid who adapted to underground life, was highly consistent with the creature that had just been killed by Qi Lin.

They used to be humans, but now they can no longer be called humans.

"Do you think this kind of creature is alone or in groups?" Qi Lin suddenly remembered that in "Dark Invasion", there are more than one humanoid monster like that, and there are almost everywhere in the cave!
