The water in the underground sewer is particularly cold, if it is an ordinary person who can't bear it at all, Lu Gengsheng must be a zombie, his body is strong, Li Zhiyuan builds a foundation and cultivates, and he has a spiritual energy to warm his body, so there is no major obstacle for the master and slave.

This waterway is very long and very wide, and it goes diagonally downward, and I don't know where it is connected.

Their master and slave kept swimming, and Li Zhiyuan didn't find anything, just when the two of them were a little discouraged, suddenly the front suddenly opened up, and a large area of water appeared, wide, and clearly an underground river.

Continuing forward, when entering the underground river, the water temperature rose a little, proving that the underground river should have a channel connected to the above, absorbing the heat of the outside air, but after they entered the underground river, Li Zhiyuan's divine consciousness, three unknown species suddenly appeared,

These three unknown species are shaped like crocodiles, about one meter long, and they are besieging them from three directions, because they are potentially underwater, so Li Zhiyuan and Lu Gengsheng can't see what it is.

"Be careful. With a wave of his hand, Li Zhiyuan sneered at three fire snake techniques...... Three fiery snakes snorted in the water, rushing towards the three unidentified species like torpedoes.

The three unknown species looked clumsy, did not dodge, and were directly hit by the fire snake, the flame emitted by the fire snake is different from ordinary fire, to put it bluntly, it is different from ordinary flames, it is transformed by aura, not to mention water, even ice can't stop it,

Boom~~Boom~~Boom~~~

All three unnamed species were hit, and their whole bodies were immediately wrapped in firelight, twisting and twitching like fish on flames, and trembling like electricity, and finally they were leaned into three pieces of coke, and they could no longer die.

However, that species seemed to have no brains, and was not afraid of death, and before Li Zhiyuan stepped forward to see what it was, there was another species of the same species, rushing towards him, Li Zhiyuan knew that it was not as simple as a water ghost, so he wanted to catch a live study, so he said to Lu Gengsheng, "Its strength is not strong, when it pounces on me, you catch it." ”

Lu Gengsheng nodded, took a step forward, and was ready to go. Ready to pounce.

There was a bang, the water roared, and the thing swooped up towards Li Zhiyuan, the momentum was very fierce, and the speed was very fast.

Just before he could pounce, Lu Gengsheng went up and grabbed it, Lu Gengsheng's sharp claws stretched out and buckled directly into the flesh of the thing.

The thing let out a low, strange cry that sounded more like a moan. However, it did not resign itself to this because of this, and while struggling desperately, it opened its mouth and bit Lu Gengsheng,

Li Zhiyuan snapped his thumb and flicked it, and suddenly an aura popped out and hit the mouth of the thing, and the thing closed its mouth in pain, and was finally successfully captured by Lu Gengsheng.

Li Zhiyuan glanced at it and said, "It's a salamander, let it go." ”

Lu Gengsheng immediately released the salamander, and the salamander escaped as if it had no life after being freed.

"It's so big, it should be an overlord salamander, and there are so many, this underground river has obviously not been discovered," looking at the wandering overlord salamander, Li Zhiyuan muttered.

"There should be a lot of salamanders in this underground river. Lu Gengsheng said.

"If there are salamanders for a while, don't hurt them again, just drive them away, this kind of thing generally won't come out of the water to harm people, our target is the water ghost, continue to look forward," Li Zhiyuan explained, one master and one slave continued to march forward,

If it were ordinary people, they would have been exhausted after traveling in the water for so long and going through a battle, but their masters and slaves were like no one.

Keep moving. The more he swam forward, the more he felt the vastness of the underground river, and suddenly, in Li Zhiyuan's consciousness, another species appeared, and that thing looked similar to an octopus, and it was exactly the same as the last time I saw it, it should be the water ghost, the water ghost obviously didn't find them, otherwise they should have fled a long time ago, Li Zhiyuan glanced at Lu Gengsheng, signaled him not to make a sound, and then the two quietly approached the thing,

Li Zhiyuan found that the thing had entered a cave, so he sped up his swimming speed, if the cave had only one passage, then the thing would definitely have a way to escape.

Li Zhiyuan swam into the cave and played a fire snake technique, the fire snake rushed towards the thing, the thing sensed, snorted, flexibly avoided, and then turned around and returned the same way, intending to escape,

Seeing this, Li Zhiyuan knew that there was only one exit from this cave, so he said to Lu Gengsheng, "Hold the exit and don't let it escape." ”

Lu Gengsheng immediately crossed the exit of the cave, there was a lot of momentum when the man was not open, the speed of the thing was very fast, intending to spare Li Zhiyuan and take the way, Li Zhiyuan waved his hand, two fire snake techniques, from the front and back to hit it, whirring twice, and finally there was a tongue of fire on the thing, Peng Di caught fire, and the thing fled with fire, but the speed was much slower,

In the end, it was grabbed by Lu Gengsheng at the mouth of the cave and lifted it up, only to see that it was indeed an octopus-like thing, but it was not an octopus, it looked very strange, constantly twisting under the flames, and screaming in pain, it was obviously not a water ghost.

Water ghosts are human souls, not in the form of matter, and the soul is bound to water, which is very easy to have resentment, and then the soul is immortal and becomes a ghost, called a water ghost.

To be precise, the water ghost is not a living creature, but now, what Lu Gengsheng is carrying is clearly a creature, although he doesn't know the name, it is very weird, but it is not a soul.

In the end, the strange thing was burned into a pile of ashes and thrown out by Lu Gengsheng.

"This is not a water ghost," Li Zhiyuan said, and the master and slave couldn't help but be a little discouraged. Lu Geng was afraid that Li Zhiyuan would be affected by this, so he asked, "Do you want to continue to investigate? Why don't you withdraw and take a rest?"

Li Zhiyuan said, "How can you give up halfway by doing things, continue to investigate, even if you can't find the water ghost, you should take a risk." ”

Continuing to move forward, in Li Zhiyuan's divine consciousness, there were a large number of salamanders, I am afraid that there are as many as ten, and the size is not small, just when Li Zhiyuan found those salamanders, he also saw a light flickering in front of him,

This light came from a cave, light blue like fluorescent stone, this light aroused Li Zhiyuan's curiosity, he decided to go over to take a look, as for the salamander, he was not afraid, he could drive away, and if he couldn't drive away, he would kill it, so he explained to Lu Gengsheng, and then swam towards the cave where the light came out.

The salamanders were really not afraid of death, and when they swam past, they all attacked one by one, forming an encirclement and besieging them.
