"what?"

Bell didn't quite understand what Su Chen wanted to do.

Su Chen followed Bell's arm and pulled the thin rope, and found that the rope was indeed different from the ordinary rope. The ordinary rope was soft, but this rope was soft in appearance, but hard in heart.

Bell noticed that Su Chen was exerting force, and let go of his fingers, and the rope was in Su Chen's hand.

He was uncertain: "You want to draw that thing out?"

Su Chen snorted and said, "That thing is likely to be a strange creature that humans have not discovered yet, aren't you interested?"

Bell didn't know what he was thinking, and didn't speak for a long time, "In such an environment, even if we draw that thing out, we may not be able to capture it."

Su Chen said: "I have a way."

He pulled the dagger from Bell's waist and waved it twice. Bell said softly, "Be careful, this is my special Swiss Army knife, it's very sharp."

Su Chen laughed twice, the dagger passed silently, and with a squeak, Bell was dumbfounded, "You want to kill me?"

Su Chen inserted the dagger back into Bell's waist as if nothing had happened, and pinched the wound that only injured the epidermis, "It's just such a wound, if you can die, then I admire you too."

Bell also reacted at this time. There was only a slight sting on his arm. Obviously, the dagger just cut through his skin. "You want to use my blood to draw that thing out."

Su Chen said: "That thing attacked you, probably not because the rope disturbed it."

Bell opened the wound so that Su Chen could draw blood, guessing: "Could it be that he can smell the blood on my body?"

Su Chen replied vaguely, he wasn't sure whether the thing smelled the blood on Bell's body or on him, because when he broke through the realm, almost half of the blood in his body was lost, even if he came here through time, The blood on his body has dried up, but his blood is special, and animals with a keen sense of smell should be able to smell it.

There are no external wounds on Bell, only a few scrapes. Although the scrapes are large, they have already begun to scab. If the smell is sensitive enough, the smell of blood should also be on him. , not Bell's.

Su Chen knew that Bell would not doubt that the blood on his body was any different from others, but he thought that when Bell approached him before, the thing would automatically retreat. His blood, that thing probably won't take the bait.

Su Chen pulled the string halfway up, wiped Bell's blood on the rope, and then slowly went down. He could hear the sound of the rope rubbing, and then calmed down.

Time passed minute by minute, Bell was looking forward nervously, the light was too dim, and he couldn't see anything with the naked eye, so he simply closed his eyes and concentrated on listening.

After a while, the rope was still very calm, but the strange gasping sound appeared again.

Su Chen leaned over. He wanted to find out what was going on with the airflow. In the silent crypt, the sound of gasping was especially obvious. Su Chen stared at the entrance of the air hole. Although he could not see the flow of airflow, it was obvious. It is noticed that at the entrance of the air hole, the airflow is very strong.

Only a finger-thick air hole can have such a strong airflow. Obviously, there must be something agitating the air below.

Su Chen wanted to let go of his consciousness and check what was under the air hole, but the system first issued a warning, and he had no choice but to give up.

Just as he was about to get up, the gasping sound suddenly disappeared, and then he felt the rope tremble slightly.

The slight tremor quickly disappeared, but Su Chen was sure that the rope had indeed moved just now, and he immediately approached the air hole. Just as his eyes were close to the air hole, he heard the sound of friction.

The sound was very small, but the speed of movement was very fast. Su Chen took a half step back, then stretched out his arms and hung his fingers above the air holes.

"Whoosh!"

He heard a very light and quick sound of breaking through the air, his fingers subconsciously folded, and then he smiled softly.

"Clap clap."

Su Chen retreated to Bell's side, handed the thing in his hand to Bell's eyes, and then said softly, "Turn on the flashlight and see what it is."

Su Chen pretended not to see the thing clearly, and sent his hand forward. Bell immediately took out a hand-held miniature flashlight from his backpack. At the moment when the light illuminated, the thing in Su Chen's hand suddenly made a sharp sound. screamed, and then began to struggle violently.

When Bell saw that thing, he exclaimed involuntarily, "Oh, mygod, what is this?"

Su Chen said: "Looking at its shape, it should be a kind of catfish."

If you don't look closely, the thing Su Chen is holding looks like a small snake, but its whole body is transparent. The two black spots on its head should be eyes, its mouth is like a catfish with two whiskers, and its head is like a catfish. Somewhat flat, but the tail is like an inverted triangle with a few spikes.

Bell carefully moved the tail of the thing forward and swung it towards his face. Bell immediately leaned back. Although he was not hit, he still felt a little chill on his face.

Su Chen felt that it was almost the same, and his fingers were slightly forced, and the thing stopped moving in an instant, "It should be living underground all the year round, so it evolved a transparent body."

Bell shook his head and said, "I have seen mutated catfish in crypts in other places, but the body shape of those catfish is not too different from that of ordinary catfish, they will not be slender and tail like this. Barbs."

He stared at the thing for a long time, and said hesitantly: "The head is really like a catfish, but its tail is very similar to a poisonous snake from Guatemala. Could it be a cross between a catfish and a poisonous snake?"

Su Chen asked in surprise: "Is there no species isolation between catfish and poisonous snakes? Can these two creatures produce offspring?"

Su Chen is a complete biological noob. He doesn't know whether a catfish and a poisonous snake can produce offspring after mating, but the little thing in his hand is indeed like the one shot by Bell, with a head like a catfish and a tail like a poisonous snake.

Bell said: "It's very likely that its tail is poisonous, how can we get it out?"

Su Chen said: "Pinch it to death and take it out."

"It's better to have a living specimen," Bell carefully took the thing from Su Chen's hand, but couldn't find anything in it for a while, "Is it still alive now?"
