Han Du already knew that the prehistoric zombie worm was able to manipulate the host, and perhaps the host could still have some autonomous mobility before it was sucked dry and wiped out, but the worm could restrain its movement at any time.

"Come and see, the redfish has a prehistoric zombie worm in its body." Han Du found a wooden stick and picked out the prehistoric zombie worm from the red fish's body, which was also a 15-centimeter silver-gray long worm.

Everyone gathered around, and the worm shrank before their eyes, and soon wrapped the stick tightly around it, just as it had reacted to the dagger before.

"Damn, these long worms are everywhere, are the waters in the cave ruled by them?" Sun Zichao was shocked.

Han Du thinks that there is this possibility, but fortunately, prehistoric zombie worms have strict requirements for the living environment, and they can't do without this cave, so naturally there is no possibility of spreading to the outside world.

Han Du thought of the worms in the glass jar again, and asked Lao Huang to show him the jar. The moment the glass jar was handed over, Han Du found that the worms wrapped around the dagger had released the dagger, but their state was a little abnormal, it turned out to be a strip of sticks together, combined into a large worm 15 cm long and the thickness of an index finger, and from the side, you could still find traces of their bodies fitting each other.

They have similar properties to the Milliped Snake.

"Ding!"

"Ding!"

"Ding!"

……

To Han Du's surprise, the combined silver-gray worm began to hit the body of the glass jar with one head, and it kept ringing, as if it wanted to rely on its own strength to break through the body and escape.

"It's the other way around, and you still want to escape, why are these little things so perverted?" Yu Shengnan's eyes were opened, she had seen all kinds of strange animals in other caves in the past, but none of the animals in this cave were strange.

Han Du didn't know where they came from, but they were also antiques that lived from prehistory to the present, and they should have gradually acquired these characteristics in the long process of reproduction, and they have been passed down from generation to generation.

Han Du wasn't worried that it would be able to break through the glass jar, and looked at the dead big red spider king next to him, which was lying there motionless, and even the worms inside tried to stay away from it, probably because he was afraid of the poison on its body.

Han Du put down the glass jar and asked Lao Huang and Cui Kai to go to the waterhole to hunt the two big red fish that swam to the edge with a bow and crossbow. They quickly completed the task, and two large red fish more than one meter long were dragged to Han Du.

Then, Han Du and Yu Shengnan worked together, and they both found prehistoric zombie worms from the bodies of the two big red fish.

At present, it can be confirmed that the large red fish in the water are also controlled by worms.

At this moment, a sudden change occurred, and the big red fish scattered in the waterhole suddenly swam, and soon formed a large swimming circle in the center of the waterhole, which was an extremely regular and strange activity scene that made people look frightened.

Yu Shengnan and the others didn't know what was going on, but Han Du understood it at a glance, this should be what was mentioned in the mission introduction, the big red fish would frantically worship a huge stone pillar in the center of a waterhole as big as a lake.

Now he jumped onto a huge stone block on the side, and looked down to see that there was indeed a huge stone pillar in the center of the big red fish swimming in a circle, which was probably formed naturally during the formation of the cave.

This giant pillar is really as big as a millstone, and there are many holes the size of eggs on the outside, and in other places under the water, there are actually many such naturally formed stone pillars, but there is no huge tower in the center, and there are no holes on it.

At this time, there was another situation, in the hole on the huge stone pillar in the center of the waterhole, some silver-gray worms began to swim out, and their bodies continued to bend and twist like lines, quickly approaching the big red fish that surrounded them, and finally drilled a small hole in the body surface of the big red fish, as if they were sucking the nutrients inside.

Their size was larger than any worm Han Du had ever seen, almost two or three times larger, and their body length was also longer than that of any worm Han Du had ever seen, generally more than thirty centimeters.

This reminded Han Du of the silver-gray worms mentioned in the system, which are male and female, male and female, and occupy the core position in the worm group, only responsible for reproduction.

Yu Shengnan next to him didn't know what was going on with these big worms that came out, Sun Zi was super whimsical, and swore and said: "I know, these big worms are the leaders of the worms, just like the elders or sect masters in the sect, the little worms can only be driven by them, and sure enough, in the biological world, they also pay attention to strength, and the strong are simply crooked!" ”

Han Du knew that he had seen a lot of the Internet when he heard Sun Zichao's words, and teased: "According to what you mean, can it be understood that all ants below 30 centimeters in the worm can only become the strong in the worm and become the leader when they grow to 30 centimeters or more?" ”

"Well, you can say this, Brother Han, you are very appropriate, those little worms are cannon fodder ants, you see those big worms piercing into the host of the little worms, and leaving in a dashing manner after sucking their fill."

Sun Zichao pointed to the water, and Han Du saw that the body of a female worm that had pierced into the body of the big red fish was indeed getting thicker, and only after the whole thing was thickened did they let go of the big red fish and continued to bend and swim back into the hole above the giant pillar.

At this time, Han Du decided to take advantage of the concentration of these big red fish to kill them all so that they could reach the other shore safely.

"Captain Yu, I think this is a good time, quickly use your explosives to blow up all these big red fish gathered together."

Yu Shengnan looked at Han Du, suddenly showed a sinister smile, and said, "It makes sense, Han Du, your suggestion is quite insidious, you can think of it." ”

Han Du was speechless for a while, this is called a bright brain, is it called making a decision immediately?

Yu Shengnan and Cui Kai immediately took action, taking out their black round tube explosives from their backpacks, these are relatively advanced modern explosives, you can set the explosion time by yourself, and the power of each explosion is also extremely huge, like the boulder where Han Du is standing, a black tube explosive can be blown to pieces.

Yu Shengnan quickly explained to Han Du how to use the black pipe explosives, and then each of them distributed three, a total of fifteen.

"Listen, I've set the time of the explosion to five seconds, everyone press the switch, and immediately don't hesitate to throw out the black tube explosives, otherwise be careful to blow yourself up."

After Yu Shengnan finished speaking, Han Du had already made a decisive move, and an explosive that pressed the switch was thrown out by him, and it landed on the top of the giant pillar surrounded by the big red fish.

Suddenly, with a bang, the black tube explosives sank in the water for a distance, and when the giant pillar fell, it exploded abruptly, and the entire giant pillar was directly shattered and scattered, and a large number of female and white eggs inside were blown out in an instant.

Patches of water were even higher in the air, crackling and falling on Yu Shengnan, who were caught off guard, and Han Du himself.

Yu Shengnan and the others didn't expect Han Du to shoot so quickly, and while getting wet, they pressed the switch of a black tube explosive one after another, and threw it one after another.
