Once upon a time there was a demon pass

"Seven-tailed fox..."

The old man guarding the mountain thoughtfully, looked at the figure that disappeared in the mist, and muttered to himself: "Sure enough, the black hair got into the black mist, and it is completely invisible..."

"Black Monkey..."

His eyes were a little strange, and finally soared into the sky, and flew slowly towards Zhenyao Pass again.

But after feeling the terrifying coercion in the distance, he shuddered subconsciously: "This is how many ruthless people have come... There are at least... twenty demon masters."

Originally quite confident in his own strength, the old man guarding the mountain, who thought that something went wrong and could escape alive, fell to the ground obediently, and turned into a gray snake again, creeping slowly towards Zhenyaoguan. He was still mumbling: "How did Yu Sheng break through this blockade..."

Swamp!

Compared to the grand occasion of Qianli Yaoyuan at this time, the swamp pond seemed exceptionally quiet.

In other words, this place is incompatible with the environment of the entire Demon Realm!

Yu Sheng silently landed on a raised stone without making any sound.

On a tree not far away, a dark gray boa constrictor lazily opened his eyes, as if sensing something, looked at Yu Sheng with cold pupils, and finally closed his eyes slowly.

Poisonous Heart Flower, it has shown its effect!

This is the hard work of the outlaw lunatics. It took half a year and sacrificed an unknown amount of manpower and material resources, and finally found three plants in the demon domain near the ghost gate!

The petals of this flower are crushed into juice and applied on the body, it will emit a strange smell, which stimulates the sense of smell!

Ordinary monsters might not be used to smelling it, but these guys in the swamp have a natural liking for the smell, as if they have labeled themselves as their own.

Yu Sheng got up slowly and stood firm on the rock.

The weeds here are very tall, and it is completely impossible to see what is below, and it is possible to fall into the quagmire at any time and gradually sink.

Yu Sheng recalled the situation on the map, walked as far as possible where there were trees, and tentatively walked to the distance.

A bat suddenly flew by from a distance, hanging upside down on a branch, making a piercing cry.

Although it is only level three, this bat is not afraid of the rest of its life, or it does not have such emotions at all.

Yu Sheng stopped, raised his head, and looked at the bat.

But the bat kept its eyes closed, and finally waved its wings again, flying away beside Yu Sheng.

The atmosphere in the whole scene was a bit weird, but Yu Sheng kept his face calm all the time, he turned up a tree lightly, and looked around.

Beside the branch, a pitch-black snake moved slightly, as if its rest was disturbed by the arrival of the rest of its life. It opened its eyes irritably, exposed its fangs, and subconsciously wanted to bite it off.

But what responded to it was a hairy hand.

This hand grabbed its neck, and a pair of eyes looked at it curiously.

Facing the provocation, wisps of evil spirit filled the air.

And there are some black silk threads mixed in the evil spirit.

"Special evil spirit, so it is like this?"

Yu Sheng looked at the black snake in his palm, thoughtfully, and finally wound it together casually, tied it in a knot, and threw it into the weeds below.

On the seemingly calm ground, a scaled head suddenly drilled out, and it was still stained with mud. It bit down on the black snake that hadn't landed, swallowed it directly, and then burrowed into the swamp again, disappearing. .

The whole scene happened in an instant, but it proved the danger of this place.

What makes Yu Sheng curious is that this place is clearly in danger every step of the way. Logically speaking, those low-level monsters should be cautious and fearful. This is in line with the current situation of the monster domain.

But even if there is a possibility of death at any time, these monsters still maintain a violent mood, even if they feel that Yu Sheng's strength is far stronger than their own, they dare to open their mouths and take the initiative to attack.

"They don't seem... to know death."

"Killing is an instinct that remains in their emotions."

"Is all this due to the influence of poisonous gas?"

Yu Sheng looked around, under the shroud of poisonous gas, he couldn't even see the scene three meters away clearly.

He didn't continue to move, but sat on the tree and took out a string of pendants with a light gray bead strung on it.

Hanging it around his neck and hiding it behind his hair, the poisonous gas that originally permeated around Yu Sheng's body seemed to fade a lot.

The depressive emotions were also greatly relieved at this moment.

"Being shrouded in poisonous gas for a long time, even emotions will be corroded, and eventually become a puppet-like existence."

"In the eyes of outsiders, the swamp pond is full of iron barrels, and all the monsters are very united..."

"But the real reason is...they have already been unknowingly controlled by a certain hidden demon master."

Thinking back to the USB flash drive that the outlaw lunatic gave him, full of data about the swamp, Yu Sheng thought about it.

Most of them are just speculations of outlaws, and only a small part has been confirmed.

The part about the poisonous gas was his guess, so Yu Sheng didn't take out the pendant immediately.

Now it looks like...

His guess was right.

The problem of poisonous gas is indeed very big.

And this is just one of the countless conjectures of the outlaw fanatics.

He has sorted out hundreds of pages of similar information!

From this we can see how much he attaches importance to the swamp pond.

As the sky darkened, the poisonous gas became much stronger than before, and even the pendant worn by Yu Sheng couldn't completely isolate it from the body.

When the swamp pond was completely plunged into darkness, Yu Sheng stopped his progress decisively. He just found a tree, cleaned up the dangers nearby, and stayed still.

In this quiet atmosphere, you can still faintly hear the rustling of the grass under your feet.

As if night fell, they all became energetic.
