When Han Du tried to pull it down, something seemed to be released from the insect's body, and it seemed that a strange electric current spread from his palm to his whole body, causing him to sit on the ground unconsciously.

At this moment, he seemed to have some kind of connection with this kind of bug, and there was a feeling of being dominated by bugs.

This situation was too terrifying, Han Du hurriedly bypassed the silver-gray insect from his hand in a circle, and went around to the last circle, he thought that he could pull the insect off his hand, but as a result, a stinging pain suddenly came from his hand, and the head of the insect had actually pierced into the skin of his palm.

When he looked closely, it turned out to be a small white hooked bone spur sticking out of the tip of the silver-gray worm, which had already hooked his skin.

Han Du hurriedly pulled hard, and a small bloody wound was torn open on his skin, but the insect was finally pulled down.

"What is this?"

Yu Shengnan in the underground river had already gone ashore, and she saw the scene of Han Du entangled with silver-gray long insects.

"I don't know, but it's certainly not a good thing."

Han Du neatly threw the long worm into the fire under the folding barbecue grill, and it took a full ten seconds to see the worm ignited by the flames, burning little by little into black charcoal.

"Lao Huang, put down the fish in your hand first."

Han Du was worried that there was more than one such bug, so he walked to Lao Huang, and Yu Shengnan followed.

Cui Kai and Sun Zichao were also attracted by this situation, the former moved the barbecue grill aside, and the latter directly put the hare in place, and gathered around to see what Han Du was going to do.

"Do you suspect that there are bugs in these big fish?" Yu Shengnan guessed Han Du's thoughts.

"Well, this silver-gray bug seems to be dangerous, we better be careful."

Han Du picked up a big fish that Lao Huang had already removed its scales and hollowed out its internal organs, but found no such bugs, and remembered that the worm just now came out of the carp's mouth, so he checked the fish scales and internal organs that had been taken out, but still found nothing.

Han Du didn't find anything, and he was in a good mood, at least it meant that this kind of insect was not everywhere in the underground river, but suddenly, he noticed that a piece of the big fish's body had a slight fluctuation, as if something was moving inside.

"Bring the knife!"

Han Du's attention returned to the big fish, and Yu Shengnan on the side took out a dagger from his waist and handed it to him.

Han Du gently slashed along the moving part, and a silver-gray long worm's body was immediately revealed inside, still wriggling.

Under the gaze of Yu Shengnan and all of them, Han Du used the tip of his knife to pick out a silver-gray long worm that was exactly the same as just now.

Looking at the long worm that was still writhing on the tip of the knife, and quickly wrapped around the back of the knife like it was entangled with Han Du, everyone's eyes widened, this dagger was very sharp, and the long worm was so tightly wound on it that it didn't even cut itself into several pieces.

"I'll drop a good girl, what kind of moth long worm is this, it shouldn't be a wire mutation, right?" Sun Zichao looked surprised.

"What do you think, the wire can only become like this when it becomes fine."

Han Du made a joke, then ignored the long worm, and continued to check on several other big fish, and found this long worm.

After Han Du picked them all out, the long worms reflexively wrapped around the blade, like a circle of iron wires tied together.

"Do you have containers? I want to seal the dagger and observe what happens behind the bugs. ”

He asked Yu Shengnan and Cui Kai, Yu Shengnan looked at Cui Kai, and he hurriedly said, "Yes, we have a sealed glass jar in our bag to collect biological samples." ”

Cui Kai quickly retrieved a cylindrical glass jar with a transparent exterior and a metal lid at the top that could be screwed on.

Han Du put the dagger in its entirety, and then tightened the metal cover, and the silver-gray worms inside were still entangled.

"Lao Huang, you take the jar, I will watch the movement inside at any time."

It is also appropriate to give the jar to Lao Huang, if something happens, with Lao Huang's vigilance, he should be able to deal with it in time.

After dealing with this matter, Cui Kai and Sun Zichao continued to prepare to eat, and Lao Huang disposed of those big fish, for insurance reasons, Yu Shengnan suggested not to eat, to be honest, it is not a taste to eat these fish now.

"Captain Yu, you've been standing in the underground river for so long, what if a silver-gray bug gets into it from somewhere on your body?"

Now that Han Du and Yu Shengnan were standing together, he looked Yu Shengnan up and down, and Yu Shengnan was covered in goosebumps when he said one sentence.

She glared at Han Du deeply before she went to find a place where no one was to check all parts of her body, if it weren't for Han Du's sudden arrival, she wouldn't be as unappetizing as she was now, and she could hear that Han Du obviously said this on purpose, probably to experience the feeling of being a prank.

If she was entangled by this kind of bug, she should have reacted a long time ago, but she had to listen to Han Du's words, because she was really not at ease if she didn't check her body.

Han Du walked along the bank of the underground river at this time, wanting to see if he could find some clues about the silver-gray long worm, but he knew that the most useful thing was to consult the system directly.

"System, you know everything, what's going on with those silver-gray worms?"

"Host questions are welcome, I am really the only one who can give you an answer to this silver-gray long worm at the moment." The system's mechanized voice sounded, and continued, "They are a kind of prehistoric zombie worms unique to this cave, the outside world was extinct as early as 80 million years ago, and so far, there are no fossil specimens to prove their existence, because they will automatically decompose after death, and no trace can be found. ”

"Prehistoric zombie worms?" As soon as Han Du heard the name, he guessed something, "Could it be that they are a kind of prehistoric creature that can parasitize the bodies of other animals and then manipulate the host to become a zombie puppet?" ”

"Yes, you were entangled in a prehistoric zombie worm before, didn't you just feel dominated?"

As soon as the system asked like this, Han Du's feeling was even worse than Yu Shengnan's feeling just now, and he hurriedly asked, "Then there won't be any problems with my body, right?" ”

The system still replied in a mechanical voice: "Don't worry, this prehistoric zombie worm is only that big, and it doesn't have enough energy to control a human, in fact, they can't control any species that is slightly larger, so only the fish in the underground river suffer." ”
