As soon as Zheng Yuan walked out of the room, he immediately sensed that the hell monkey was in the north.

He didn't think about it for a moment, so he quickly started his wind defense and chased after him.

However, because the wind is useless in the dead wilderness, we can't resist the wind and the speed can't reach the fastest.

In the blink of an eye, it was already bright.

Zheng Yuan did not rest for a while, and continued to chase forward.

He felt that the hell monkey was hiding tens of thousands of miles away.

On the night of the third day, Zheng Yuan came to a dark swamp.

Everything in the swamp was black and bubbling like boiling soup.

This is what the eagle in the cloud called the black prison swamp.

The endless forbidden area is hidden in it.

The black prison swamp is very dangerous. It not only hides the evil spirits of black alligators who suck human blood essence, but also permeates with extremely corrosive biogas everywhere.

The reason why Zheng Yuan didn't let Liu Shuangyan come here was that he knew they didn't have the ability to pass through the black prison swamp.

If you do anything to force your way through, you will lose your life in vain.

Even he didn't have much confidence to survive.

However, he will not shrink back in any case.

It's hard to know where the endless forbidden area is. Even if you have to fight for your life, you have to go in.

Zheng Yuan stopped about five meters from the black prison swamp. Then he picked up a fist sized stone from the ground and threw it into the black prison swamp.

Soon, there was a black wind in the black prison swamp, and the stone was crushed.

This tornado is formed by marsh gas. It is extremely poisonous. Once it is blown, the whole person will be corroded immediately.

From ancient times to the present, many practitioners who tried to enter the black prison marsh were poisoned by the black prison marsh wind.

The black swamp wind dissipated after about three minutes.

Zheng Yuan then picked up two stones and threw them in different directions.

Soon, where the two stones passed, there was another black swamp wind.

Zheng Yuan did not stop for a moment, took a yellow grass leaf, and then applied the secret method, so that the grass leaf quietly floated into the black prison swamp.

This time, there was no more black swamp wind inside.

After flying about 500 meters, the grass leaves quietly fell into the swamp.

The black marsh wind is still not blowing.

Zheng Yuan suddenly understood, the original black prison marsh wind heard the movement will blow up.

If this is the case, then he will have a way to enter the black prison safely.

He could fly into the black swamp without making any noise.

In order to verify this conjecture, Zheng Yuan took out a piece of cloth from his space ring, and then used a secret method to float it into the black prison swamp again.

This time, there was still no wind in the swamp of the black prison.

Zheng Yuan heart a joy: "sure enough, no problem."

Soon, the cloth flew to about 1500 meters.

However, just as the cloth was about to fall down, a dark shadow suddenly appeared in the black prison swamp. It swallowed it all at once, and then disappeared.

It was only a second from the appearance to the disappearance of the shadow, which made people think it was too much to see.

Zheng Yuan, if not for his good eyesight, would be mistaken for an illusion.

Although Zheng Yuangang could not see the true face of the shadow, he had guessed that it was probably the legendary black alligator spirit.

Alas, even if we can avoid the black swamp wind, we can hardly avoid the black alligator spirit.

This black prison swamp is not generally difficult to enter.

However, Zheng Yuan has thought of a way to deal with it.

He didn't hesitate any more. After summoning hell, he launched the chaotic wind control technique, and then he lay like a cloud and floated into the black prison swamp.

As he flew cautiously, he tried his best to open his mind and carefully observed the movement around him.

However, he found that the black prison swamp suppressed the divine consciousness, and he could only observe the range of 100 meters.

After a while, Zheng Yuan floated to about one thousand meters.

Suddenly, his heart was alert, and a very strong sense of crisis hit his heart.Almost without hesitation, he waved the hand of hell and attacked fiercely.

As soon as his hand hit out, a shadow came out of the swamp.

This time, Zheng Yuan finally saw clearly.

This is a humanoid crocodile monster.

Its head is an alligator head, but its body is a bit like a human. An alligator has a long tail, and its whole body is covered with thick skin like an alligator.

In a flash of lightning, Zheng Yuan's fist hit the black alligator's head.

The black alligator spirit screamed and dived into the swamp.

Zheng Yuanxin called it a fluke. If he didn't move faster, he might have become the food of the black alligator.

After the evil spirit of the black alligator, Zheng Yuanji did not delay for a moment. He quickly drifted to the left and went straight out for about 30 steps.

Just then, a fierce marsh wind came up where he had been.

It turned out that his attack on the Black Crocodile spirit immediately caused a lot of noise.

Zheng Yuan sighed in his heart that the black prison swamp was too sensitive.

Fortunately, he had been prepared for a long time, otherwise he would be crushed now.

It turned out that this was the way he dealt with it at the beginning.

Zheng Yuan found that the greater the movement, the greater the black prison marsh wind, and the longer it lasted.

For example, the current biogas wind has been blowing for six minutes without stopping.

Before the marsh wind disappeared, Zheng Yuan did not dare to move, otherwise he would be attacked by the marsh wind.

About ten minutes later, the marsh wind completely disappeared.

So Zheng Yuan continued to drift in.

Along the way, Zheng Yuan encountered three attacks of black alligator evil spirits and black prison marsh wind, but they were all solved by him in the same way.

About half an hour later, Zheng Yuan came to the depths of the black prison swamp.

There is a huge black pit with a radius of 100 meters.

The dark pit is so dark that it can't be seen to the end. It looks like the entrance to hell, and it's like a big mouth of a beast, which makes people afraid.

According to the eagle in the cloud, this is the place of the endless forbidden area.

Originally, the endless forbidden area was completely revealed. Later, for no reason, it became a big pit.

Later people did not know the existence of the endless forbidden area.

Even if many people come here and see such a big black pit, they will be deterred.

But Zheng Yuan didn't think much and jumped in.

He knew that the endless forbidden area must be in the big black pit.

Because he already felt that hellhound monkey was hiding in it.

So, even if it was the entrance to hell or the mouth of the beast, he would never flinch.
