Yu Feng and Tu Hongxing saw Xia Yanru enter the passage and hurriedly followed.

As the three of them walked, they found that although there were traces of artificial chiseling, it was more like a naturally formed rock passage, and the traces of those chiseling were probably to expand the stone cave so that people could enter and exit freely.

The trend of the stone path is all the way down, and it is not the kind of place where you often encounter a turn, but fortunately there is no fork in it. The three of them walked for more than an hour, and they were already tired and sweating, and Yu Feng and the two of them passed by the previous fall, and they were slightly injured in the end, and they did not brace hard, so they proposed to rest temporarily.

Xia Yanru touched the thin sweat on her head, she was not too tired, while the two of them were resting, she herself concentrated on exploring the surrounding space, especially how long this passage was.

After resting for more than ten minutes, the three of them set off again and continued to walk down, and after walking for less than forty minutes, a light finally appeared in front of them, very faint, but it also meant that they might have finished this passage.

At this time, the three of them didn't have the heart to think about where the light came from, and when they got out of the passage, they were greeted by a lake, and the lake was scattered with some moving lights, and those bright lights illuminated the entire cave environment very clearly.

"There's even an underground lake here!" Yu Feng said in amazement.

"What's shining in the lake?" Tu Hongxing's focus was on the constantly moving lights, because they were not close, and he couldn't see what they were for a while.

Xia Yanru was also a little curious, walked a few steps briskly to the lake, looked at it, and couldn't help but be a little dumbfounded, those bright spots turned out to be silver and slightly transparent, but the head had two short roots, and the light came from the top of those two whiskers.

"What kind of fish is this? It's weird to look at. Yu Feng and the others also followed to the lake, and Yu Feng was curious about these strange-looking fish that could still shine.

"I don't know." Xia Yanru shook her head, she knew several kinds of fish that could glow, and the kind in front of her was a bit similar to monkfish, but the monkfish was a little ugly, and there was only one tentacle similar to a luminous device on its back, and the fish in the lake not only had two glowing tentacles, but also grew on the top of their heads.

Looking around, Xia Yanru felt that this might just be a naturally formed cave, and it didn't seem to have much to do with the tomb, except for the passage they had just come out of, they couldn't see other passages for a while.

And they walked all the way down the passage, and they didn't encounter any other fork in the road, as if they had gone from one enclosed space to another after a long stretch.

Obviously, after being curious about the strange fish in the lake, Yu Feng and the others also began to look for another way out, but after careful observation, they didn't see any other passage like Xia Yanru.

"Could it be that the entrance is underwater?" Tu Hongxing's mind suddenly opened up, this is a closed cave, only this underground lake looks likely.

"It's really possible, but we don't have diving equipment, and we don't know how deep this lake is, so it may be dangerous to go down rashly." Yu Feng frowned as he looked at the underground lake.

"I'm good at water, so I'll try to go down and have a look." Tu Hongxing suggested that this lake was the only way out now, and if they didn't want to be trapped here, there was only this way.

"Be careful." Xia Yanru didn't stop it, there was space all around her that she could explore, and there were also under the lake, but the spatial structure here was too complicated, and she couldn't accurately judge the correct passage.

"Tie the rope, and if you find something wrong, pull the rope immediately, and I'll pull you up here." Yu Feng saw that Xia Yanru had no opinions, and he also knew that it was the easiest to let Tu Hongxing explore the way, but out of caution, he still found a rope and tied one end around Tu Hongxing's waist, and then dragged the other end tightly and wrapped it around his arm a few times.

After doing all this, Tu Hongxing nodded at the two of them, and began to walk towards the lake, but after only walking a few meters, he retreated with a bitter face, lifted his two trouser legs and saw that there were a lot of blood spots on those two legs.

"This fish stings." Tu Hongxing gritted his teeth and couldn't make a sound, feeling a little unhappy in his heart, it was really unfavorable to be a teacher, and he was forced to move forward by those strange fish just a few steps after going down to the lake.

"Grass!" Yu Fengna scolded, "Then what should I do, I can't go down to the lake, and I can't be sure if there is an entrance underneath." ”

Xia Yanru also frowned, there are not many strange fish in the lake, but once the siege is up, no one can bear it, so we must find a way to lure these fish away.

After thinking for a while, Xia Yanru took out a tooth knife and slashed it lightly in the palm of her hand without hesitation, and immediately blood flowed out, and before the blood dripped to the ground, Xia Yanru stretched directly into the lake.

Yu Feng and the others were taken aback by her series of movements, and before they could react, they were stunned by the scene in front of them, only to see those strange fish swarming towards Xia Yanru's palms.

"Let's try again." Xia Yanru shouted at Tu Hongxing, who was stunned.

"Oh, good, good." Tu Hongxing woke up suddenly, didn't care about the doubts in his heart, and went down to the lake again, and a magical situation appeared, those fish seemed to not see him at all, and they all bypassed him and went straight to Xia Yanru's direction.

Such a good opportunity, Tu Hongxing naturally didn't dare to miss it, a Monza went deep into the lake, the underwater environment was dim, but fortunately, he could still see clearly, after diving for about 1 minute, there was really a stone gate under the lake, and he guessed that behind the stone gate should be the passage to leave.

Tu Hongxing's water quality is good, so he simply continued to dive to the stone gate, stretched out his hand and pushed, it seemed that he could push, but he was the only one who had some effort, and he was also worried about the situation above, so he checked it for a few seconds, and then he swam back decisively.

At this time, on the edge of the lake, Xia Yanru had already withdrawn her hand, and the bloody wound had been bandaged by Yu Feng with gauze, as for those strange fish, they still gathered by the lake and had no intention of dispersing.

"Are you crazy?" Yu Feng scolded in distress.

"It's just a minor injury." Her face was slightly pale, Xia Yanru withdrew her bandaged hand indifferently, her body had been transformed by the ability, and she had drunk the spring water for so many years, so the blood in her body had undergone abnormal changes, which she had discovered in the last days.

So as long as she is out on a mission, what she is most afraid of is bleeding and injury, because she is afraid that her blood will attract some mutant animals, if she encounters a mild one, it will be fine, once she encounters a violent mutant animal, it will inevitably be another big war.

She just tried it just now, in fact, she wasn't very sure if her blood could attract these strange fish at first, but fortunately, the result did not disappoint her, but it also deepened her idea of not being easily injured and bleeding.

There was a sound of water, Tu Hongxing came out of the lake, and quickly came to the lake, and at this time he also saw the bandaged palm, frowned and said, "Sister Xia, if you encounter this kind of thing in the future, you can hand it over to me and the madman, we two have rough skin and thick flesh, and it will not hinder you from putting some blood." ”

"That's it, you said that we two big men are here, where can you use yourself to harm yourself, you are not allowed to do this again in the future." Yu Feng said in agreement, and his attitude was also very resolute.

"Your blood is useless." Xia Yanru shook her head and didn't explain too much, where did ordinary blood have her kind of effect, even if the blood of these two people was drained, it might not have much effect.
