"This is really an interesting question, why do these crocodiles never come ashore to attack human monks?" Suddenly realizing this problem, Cheng Yu became interested again.

This swampy area is about 100 kilometers wide, and I don't know how many purple crocodiles there are, but it seems that no crocodile has ever come ashore to attack humans.

Thinking about it this way, when the dozens of people came back just now, these crocodiles went to a place more than ten meters away from the shore and said that they seemed to have given up the pursuit.

In order to verify his idea, Cheng Yu walked to the shore and stared at the dozen or so crocodiles watching him.

Those crocodiles moved, and the strange thing was that they were only scurrying sideways around, but they didn't dare to approach Cheng Yu.

"Heh, it's kind of interesting, what do you say you are afraid of?" Seeing this strange phenomenon, Cheng Yu stood up and ran along the edge of the swamp.

"Big brother, look, that kid ran away, should we catch up with him!" Seeing Cheng Yu suddenly running, he said anxiously.

"Hurry up and follow and see what this kid is doing?" The eldest brother also noticed Cheng Yu's strange behavior, and led a dozen of his subordinates to hide in the bushes and follow.

Cheng Yu ran ten kilometers in one breath and then stopped, sat on the shore and kept observing the water.

"Why haven't they come out yet?" Cheng Yu sat for twenty minutes, but there was no movement on the water, Cheng Yu was anxious.

Boom~, Cheng Yu picked up a stone beside him and threw it into the swamp, only to see a few ripples on the surface of the water, and then there was nothing, and it returned to a calm.

"Hey, what's going on? I haven't even come out yet?" Looking at the calm mirror-like water, Cheng Yu thought puzzled.

Seeing that these crocodiles kept coming out, Cheng Yu suddenly released the breath on his body. Bang ~ Bang ~ Bang ~, suddenly a dozen purple crocodile heads emerged from the swamp.

"So if I don't release my breath, I won't attract your attention?" Suddenly, Cheng Yu discovered an important piece of information, these crocodiles were sensed by the breath of human monks.

"But when you fly, you release the aura on your body no matter what, even if you use some concealment skills, you can't completely hide the aura on your body. And these purple lotus flowers can improve the sense of smell of these crocodiles, they will become very sensitive, and they can feel a little peculiar smell, unless they ...... "Seeing that these crocodiles were the same as those before, they found Cheng Yu's storage, but they have been scurrying and slapping the water more than ten meters from the shore, and then thinking about the situation in the Kunlun monk Tongguò Death Swamp at that time, Cheng Yu was suddenly surprised and searched around.

According to Cheng Yu's reasoning, there must be something on this shore that makes them taboo, so they don't dare to go ashore. Just like what happened to the Kunlun monks at the beginning, they must have this kind of thing on their bodies, so those crocodiles would not dare to step forward at a distance of more than ten meters away from them.

"Big brother, what is that kid doing? Could it be that he has discovered us and is looking for us?" Bursting Tooth said a little nervously when he saw Cheng Yu looking around and searching.

Smack~, "Brainless guy, we are so far away from him, how can he find us." The eldest brother slapped his head angrily and scolded.

"That's... Big brother, what do you think he's looking for?" asked Bursting Tooth, rubbing his head.

"Who knows what this kid is doing? Look at his happy face, could it be ......" The eldest brother shook his head unknowingly, and then suddenly a flash of inspiration flashed in his mind, and he said happily.

"No, I think he's more like he's lost something. Burst touched the two bursting teeth in front of him and said.

Smack~, the eldest brother slapped him again, "Say you're stupid, you're still addicted, right, have you ever seen someone so happy when you lose something?"

"Big brother, are you saying that what he's looking for can lead to this death swamp?" said Sharp Mouth.

"I don't know, maybe!" said the eldest brother, shaking his head.

"TNND, what is it that keeps these guys from coming ashore? Why don't I catch a crocodile and try it? Damn, it's getting dark. At this time, Cheng Yu noticed that it was already dark, and a bonfire was lit up in the distance.

"Looks like we'll have to look for it again tomorrow. Cheng Yu had no choice but to stop looking for that magical thing.

It's getting late, although Cheng Yu can see at night, but it is still inconvenient compared to the day, in this case, there are clues anyway, so there is no hurry.

Cheng Yu also found a big tree to sit on it, took out wine and food, and ate it.

"Big brother, that kid is resting, let's eat something too?" Seeing Cheng Yu hiding in a tree eating and drinking, he burst his teeth and smacked his mouth and said.

"All right, but you're going to take turns watching him tonight, and you're going to let me know when there's any action. The eldest brother thought for a while and said. If that kid really has the ability to find a way through this death swamp, he can't take it lightly and let him run alone.

"Got it, big brother. Several of them took out the food they had prepared and began to devour it.

In the middle of the night in ――――――――――――――――――――――, Cheng Yu didn't have the mind to meditate and cultivate, first, there were many people here, and he didn't dare to settle down lightly. The second is that I have been thinking about this strange phenomenon of the swamp of death.

Whoosh~, Cheng Yu flew down from the tree, jumped to the shore of the swamp, and looked at this purple lotus flower through the bright moon in the sky.

"What is it that makes the water, plants and creatures in this swamp so strange, and what makes these crocodiles afraid to come ashore?" Cheng Yu walked to the edge of the swamp and scooped the purple water with his hand, thinking curiously.

"So cool water. Feeling that the water in his hands was cold, Cheng Yu quickly threw the water out.

Just when the water in Cheng Yu's hand was thrown on a few dwarf grasses growing on the edge of the swamp, a strange thing happened, the moonlight in the sky actually emitted a white light on the dwarf grass, and then the small hailstones on the tips of these dwarf grasses actually bloomed, revealing a white flower in each dwarf grass.

"Hmm, it stinks!" I didn't expect such a white and beautiful flower to emit such a strange smell.

Wow~Bang~Wow, Cheng Yu suddenly saw several crocodiles emerging from the water, and then fluttered and swam into the distance.

"Hey, is this ......" Seeing this scene, Cheng Yu suddenly thought of surprise.

Cheng Yu stood up and released all the momentum on his body, and after a while, there was still no crocodile on the water. Cheng Yu looked at the flowers under his feet, then picked up the dwarf grass, and then threw it at the crocodile that emerged from the water in the distance.

Pap~Papa~Papa~, as Cheng Yu expected, the dwarf grass fell to the water, and those crocodiles swam away into the distance.

"Haha, it's really you!" Finally found the answer he wanted, Cheng Yu collected all the flowering dwarf grass and sealed it with a ban, otherwise he wouldn't be able to stand the smell.

After finding the answer, Cheng Yu was in a good mood, turned around and prepared to go back to the tree to sleep. But after taking a few steps, he walked back again, and the momentum on his body exploded again. This time, without the white flowers, more than a dozen crocodiles suddenly emerged more than ten meters from the edge of the swamp.

Cheng Yu pulled a few unflowering dwarf grasses from the side and threw them down, and the same situation appeared, these crocodiles quickly swam away, but the distance they swam out was not as far as the effect of the flowers.

Seeing this scene, Cheng Yu understood a truth, these dwarf grasses also have this strange smell, but it is not so obvious, and it is generally difficult for people to smell it, but after these crocodiles have absorbed the fragrance of this purple lotus for a long time, their sense of smell is much more sensitive than that of humans, and they can feel this smell at a distance of more than ten meters, so these crocodiles dare not step forward when they fly to the side of those Kunlun monks more than ten meters.

But after the dwarf grass blooms, the smell is obviously so strong that even they can smell it lightly, let alone these crocodiles with a sensitive sense of smell, but why are they so afraid or disgusted by this smell?

Forget it, why do you study this yourself? Everything in the world is mutually reinforcing, and it is not surprising that they are naturally taboo about this smell.

Cheng Yu didn't dig any further, and happily jumped to sleep on the tree alone.

"Big brother, that kid has made a move. After Cheng Yu returned to the tree, Bursting Teeth hurriedly ran to the eldest brother and shook him awake.

"What? Where is that kid moving?" Hearing Cheng Yu's action, the eldest brother was energetic, and quickly got up and asked.

"It's over there!" Bursting Tooth pointed to the place where Cheng Yu had sat just now.

"Huh, what about that person?" the eldest brother didn't even see a ghost in the direction pointed by the teeth, thinking that he hadn't woken up, and rubbed his eyes vigorously, but there was still no figure, and said anxiously.

"The boy sat there for a while, and now he's back to sleep in the tree. ”

Bursting Tooth said honestly.

"You idiot, didn't I tell you that you would come and wake me up as soon as he moved?"

"Big... Big brother, I... I thought he got up in the middle of the night to pee, so... That's why I didn't dare call you, but I saw what he did!" said Bursttooth, rubbing his head and shrinking his neck.

"And what did he do?" the eldest brother asked curiously.

"He just sat there and threw a handful of weeds!"

"It's as simple as that?" the eldest brother asked puzzled, getting up so late in the middle of the night just to throw weeds into the water?

"Hmm. Absolutely true. Bursttooth nodded in the affirmative.

"Weeds, let's go, let's see. The eldest brother waved his hand and walked towards the place where Cheng Yu had sat with bursting teeth.

"Big brother, this is it, he just sat here and threw weeds. Coming to the edge of the swamp, he said with his teeth, pointing to the field.

The eldest brother stood aside and looked around to see nothing strange, and then looked at the water and saw a weed that could be seen everywhere on the edge of the swamp, so he pointed to the grass and said, "Is that the grass?"

"It's... It should be!" Bursttooth also recognized the grass, and said weakly.

Smack~, another slap, "Useless things, go back!" The eldest brother was angry and turned away.

"It's really this grass. Bursting Tooth rubbed his head and muttered quietly behind him.
