Cui Kai also showed a tense mentality, and it could be seen that he had a very close relationship with those dead players.

"Okay, just rush to your strength, I've decided, go down with you." Han Du clapped his hands, and his sudden statement confused Yu Shengnan and the others.

"Han Du, why can't you understand the words, is it so difficult for you to return the same way after eating? To be a travel friend to do your part, are you a little obsessed? Yu Shengnan's brows furrowed slightly.

Han Du had a headache, and said solemnly: "Captain Yu, how do you want me to explain to you, we are really not hot-headed donkey friends." ”

Yu Shengnan and Cui Kai still didn't believe it.

But in the end, they really couldn't resist Han Du, so they gave up persuading Han Du to lead the team away, they also remembered Han Du's skills outside, even Cui Kai, who won the national martial arts championship, was not his opponent, maybe he was more reliable than them in danger.

At this time, everyone had eaten almost, packed up the things on the scene, and everyone discussed and continued to walk.

"Han Du, test you, in this situation, which direction should we go in if we look for those red-faced and white-haired monsters?" Yu Shengnan already had a judgment in his heart.

Han Du knew more about this world-class karst cave than Yu Shengnan, and looked around the huge karst cave that was full of white, and his gaze naturally fell on the direction of the lower reaches of the underground river.

"Going downstream of the river, the habitat of the red-faced white-haired monster should be in the area with the richest cave ecosystem, and the downstream is more intensely washed, it is estimated that there is a wider space, and there will be more creatures gathered, maybe there is a huge waterhole that has been washed out downstream."

"That's right, there must be more than one waterhole in this huge cave, and there may even be several underground rivers, but we haven't seen them yet."

Yu Shengnan's eyes became appreciative when he looked at Han Du, in fact, how did she know that Han Du had long known that this world-class karst cave was divided into three layers, and there was a huge deep pool in the third layer, and there were schools of carnivorous big red fish in it.

Now that they all had plans, the group began to set off, all the way down the underground river.

After leaving the huge space behind, they slowly entered a corridor-like passage, Yu Shengnan and Cui Kai regarded themselves as professional expedition members, leading the way in front, and Han Du and them followed behind.

As he walked, Han Du suddenly stopped, and looked at the uneven stone wall of the cave opposite, on which there was a dark red creature lying on it.

This should be a small snake, with a body length of more than thirty centimeters, and it seemed to find that Han Du stopped to observe it, it moved, but accidentally, it rolled down from the stone wall of the cave, fell to the ground with a click, and broke into three sections, right in front of Han Du.

It was the first time Han Du had seen a snake that could be broken, and he squatted down to take a closer look, and the three-section broken snake was actually slowly wriggling and reconnecting into a complete snake.

Then, in front of Han Du, the small dark red snake that had been reconnected into one twisted forward and ran......

"Isn't this snake amazing?" Earlier, Yu Shengnan found that Han Du had fallen behind, and followed him to take a look, just in time to see the escaped little snake and Han Du's strange look.

"Yes, is there anything strange about this snake? Why is it still connected after it is broken? Han Du stood up and followed the little snake all the way.

"It's called a thousand-foot snake, it can automatically decompose and combine, and it is distributed in the area of Shennongjia, Hubei, if you use a stick to pluck it, it will disperse into a lot of small insects, and after a while, it can gather again into a complete snake, which is why it can be reconnected after it breaks."

"So it's not actually a snake?" Han Du saw Cui Kai in front of him stop the snake and used a crossbow arrow to pluck it, and sure enough, it immediately dispersed into a lot of small insects.

"Well, yes, but whether the thousand-legged snake is an annelid or an arthropod, and which subject it belongs to, has not yet been discovered."

After Yu Shengnan finished speaking, he walked to Cui Kai's side, and Han Du, Sun Zichao, and Lao Huang also surrounded him.

The leopard next to him saw so many insects on the ground, jumping left and right all the time, and it seemed that he was also a little uncomfortable with these dense insects.

After Cui Kai stopped fiddling, these insects really began to reassemble, and it didn't take long for them to change back to their original appearance of more than thirty centimeters long.

Then, it ran away again, running forward in front of so many of them in front of Han Du......

"Cui Kai, take a biological sample jar, catch this thousand-legged snake and bring it back to the people in the institute for research."

Yu Shengnan's order, Cui Kai immediately executed, so a group of people chased after the thousand-legged snake more than 30 centimeters long, and it had already chased it, but it suddenly turned around and drilled into a gap next to it, and disappeared all of a sudden.

Originally, everyone was a little annoyed that the prey in their hands ran away, but within ten seconds, the thousand-legged snake came out of the gap in a panic, followed by three red spiders the size of little fingers.

Following, without waiting for Han Du and them to catch the thousand-legged snake, there were a steady stream of spiders crawling out behind the three red spiders, looking exactly the same.

"Be careful, all backwards!"

More and more red spiders crawled out of the cracks, and the number quickly increased from dozens to hundreds of thousands, Yu Shengnan hurriedly screamed, in her experience, this weird red spider is mostly highly poisonous.

Han Du and they all retreated, and the thousand-legged snake was not so lucky, and was quickly entangled by countless red spiders, although it immediately dispersed into a large number of insects to escape, but the number of red spiders was too terrifying, like a red wave, easily drowning all the escape insects in the wave.

Then I saw a red spider biting insects one by one and returning to the crevice, and spiders were constantly spinning silk to wrap the body of the insects. It seems that some kind of substance has been injected into the body of the spider in its mouth, and all the insects are immediately unconscious, and it is estimated that they have been poisoned to death.

At this moment, there were still a large number of red spiders crawling out from the gaps, and there were already several thousand, Han Du had a bad premonition, looked at Yu Shengnan, who had a deep face on the opposite side, and shouted, "Do spiders live in groups?" ”

"Spiders are basically solitary, but I've heard that there is a kind of spider that lives in groups, but it doesn't look like this, and the number of spiders living in groups is not as terrifying as this, so this may be a new species of spider that has not been discovered." As Yu Shengnan spoke, he was quickly thinking about what equipment he was carrying to deal with these red spiders.

"Then we are really fortunate to have discovered a new species...... Han Du smiled bitterly.

Immediately, the spider army seemed to have been assembled, and they touched each other with their tentacles, as if they were transmitting information, and then they automatically divided into several groups and pounced on Han Du and them.

This is the strategy, against large targets, the red spiders should have a skilled offensive strategy.

Spider Sea tactics, concentrating superior forces, fighting more and few, and bullying the few with the crowd, they must be very good at it.
