The funnel-shaped pit looks very deep, but it is not very deep, twenty or thirty meters, probably because at night, trees grow on the pit wall, so it feels very deep.

The bottom of the pit is in a long shape from west to east, Lin Haoran looked at the weeds and ground vegetation at the bottom of the pit, all of them fell to the east, searched in this direction, and sure enough, as Lin Haoran guessed, he found a hole about one meter in the bottom of the pit in the east where the trees were most luxuriant.

"Judging from the traces at the entrance of the cave, it is true that the cave is often entered and exited by reptiles. Ah Cai turned on the flashlight and carefully checked the hole and said.

"Reptiles, big snakes? Look, almost the entire entrance of this cave has signs of new wear, not a snake as big as a meter, don't scare me. Wu Gaoqiang said.

"It's not a snake, look, there's two faint footprints here, damn, it can't be a crocodile. Ah Cai said.

"I've never heard of crocodiles living in caves, even if there are underground rivers and pools in them, crocodiles won't climb out of the mountains. Wu Gaoqiang said with a smile.

"Well, it's really not a crocodile, I guess it's a lizard. You see, the toe in the middle of this footprint is very long, and the other four toes are very short, and the proportion of crocodile toe length should not be so large. Lin Haoran pointed to the footprints and said.

"Well, you're right. Regardless of whether it is a crocodile or a lizard, I think we have really found the right place this time, Brother Wu and Sister Zheng have said that monsters are four-legged, and lizards also meet this condition. Wu Gaoqiang nodded and said.

"Three bosses, did you five guys crawl into the hole, otherwise how could you not see them? Xiao Guo suddenly interjected.

"Yes, they're in the hole, and I've been keeping an eye out for them, but it's hard to say if they're not all in there. "Among Lin Haoran's subordinates, Ah Cai is not the most capable of fighting, but he is definitely the most rich in miscellaneous studies and has the most ideas.

"Dr. Lin, shall we chase it in?" Mr. Wu said.

"Angkor, please listen to where they are, can you hear the sound in the cave? "Lin Haoran's idea is definitely to go in.

Wu Gaoqiang turned his head sideways and listened to the entrance of the cave, but did not hear any movement, and irradiated the cave with a strong light torch, and found that although the entrance was small, the space inside was not small at all, at least two meters wide in height.

"We came down half an hour late, and we probably walked far, or there were many turns in the cave, so we didn't hear anything. The hole is very big and the trend is downward, and I think if we are not afraid of the smell, we should chase it directly. Wu Gaoqiang said.

"However, if there is no moving air in such a deep hole, there may be poisonous gases in it, boss, this must be prevented. Ah Cai said.

"You're right, I'll give you a pill and put it under your tongue. "Lin Haoran gave everyone one Baijie pill, with such a detoxification product, there should be no problems.

It was still Wu Gaoqiang who opened the way, and his downwind ears were ten thousand times better than his eyes in this kind of cave.

Lin Haoran was still in formation, and the four mermaids climbed into the hole, climbed two or three meters, and when the hole was wide, he got up and walked straight.

The air in the cave was not turbid, but it was warmer than the outside, and after walking a few meters down, Lin Haoran tapped some saliva with his finger, stretched out his hand in the air and sensed it, and found that the air was actually convection.

The air is convection, either there is another outlet, or there are cracks and small holes that go straight to the outside of the hole.

"It's strange, when I was on the top of the pit just now, the air was so stinky, but now when I enter the cave, it doesn't stink, don't those stinking sources emanate from the cave?" Xiao Guo muttered after walking more than ten meters.

"Those may be monster excrement, hehe, this monster is really a thing, and he loves to clean so much. Ah Cai smiled.

"You haven't heard that monsters are human, and they have intelligent ....... Wu Gaoqiang said.

"According to you, we will soon be able to meet monsters, and if they live very deep, even if they have the wisdom to love cleanliness, they will not be able to run for half a day to. Ah Cai smiled.

"It's hard to say, we're all in, and it shouldn't take long to unravel the mystery. Hey, this cave keeps going down, and I feel like we're almost at sea level, and look, the rocks in the hole are starting to get wet, and maybe if we go down again, there's an underground river. Wu Gaoqiang observed the ground and said.

Everyone walked a few meters, the cave got bigger and bigger, but did not continue to go down, but went straight horizontally, walked a few meters, turned a corner, the hole was bigger, no longer round, but flat, two or three meters high, four or five meters wide, and whether it was the bottom or the top, or the wall of the cave, it was very regular and smooth, as if it was dug out by hand.

"Look, there must be large animals in this cave, it's strange, don't say that it is difficult to find wild large animals here, that is, the entire Lingnan Province, why are there such large animals here?" Ah Cai said as he looked at the scratches on the wall of a cave.

"Well, that's all the more proof that we've found it, and those monsters are in this hole. Wu Gaoqiang was very excited.

"But where did they go, how long is this cave, I looked at the time, and we walked in the cave for half an hour. Xiao Guo was a little scared. 、

"Don't be afraid, as long as there is air in the cave, you don't have to be afraid to walk for a day, we have prepared enough dry food to eat for three days. Lin Haoran said.

Xiao Guo stopped talking, and the four of them hurried while inspecting, leaving more and more traces along the way, becoming more and more obvious, and the cave was left and right, up and down for a while. After walking for another half an hour, Wu Gaoqiang suddenly waved everyone to stop.

"In front, they are in front. Wu Gaoqiang tilted his head and listened.

"Go, speed up, but be careful not to let them find out. Lin Haoran waved his hand and walked in front and said, everyone was very excited.

"Lin Haoran, don't worry, they are fighting, hey, why did they fight among themselves?" Wu Gaoqiang was surprised.

"Did you find a treasure that was unevenly divided, so you killed each other? Ah Cai smiled.

"No, it seems to be for a companion, oh, they were attacked by monsters....... "Wu Gaoqiang is really smooth.

"I didn't listen, I touched it and said, I opened it, and they followed me closely. Lin Haoran took the lead, as if he could see things in the dark, and he ran very fast without turning on the flashlight.

started to go down again, Lin Haoran suddenly slipped under his feet, and almost fell.

When I turned on the flashlight, I saw that there were blood stains on the smooth stones on the ground, in addition to water, I don't know if it was those men in black or monsters.

"Be careful, there's water on the ground, stop, there's a waterhole in front of ....... Lin Haoran stopped.

"It's weird, why is there no silence, where have all those guys gone?" Wu Gaozhi said in a low voice.
