Behind him, the flower butterfly also followed, and the speed shown by Lu Chen made it a little difficult for him to keep up.

And she obviously felt that in order not to put too much pressure on him, Lu Chen actually slowed down his pace.

"Whew!"

The moment Lu Chen rushed into this ancient forest, the surrounding light gradually became dim, and the smell of decaying leaves in this forest permeated from all directions.

After entering the forest, Lu Chen actually saw a crowd of people not far away.

In this crowd, Lu Chen didn't find any demonic aura on them, although they were not infected.

The strength of these cultivators turned out to be the strength of the Xuan Rank, and they could be said to be people of the same level as Lu Chen.

But after they saw Lu Chen, apart from showing a surprised gaze, they didn't dare to disturb the two of them rashly.

However, Lu Chen's strange dress still attracted their attention.

However, they themselves have a strong awareness of this danger.

In addition, Lu Chen didn't intend to disturb them, but quickly swept over them.

After all, his purpose at this moment was not the people of this ancient region.

He believed that this place, isolated from the human world, was part of the human world.

That is, in the old area, the atmosphere of the past is still inherited.

But judging from the clothes in the crowd, this kind of dress that belongs purely to ancient times also completely confirmed Lu Chen's judgment.

And judging from the expressions on their faces, they looked very vigilant, I am afraid that in this place, there are many spirit beasts or other beings infected by demonic energy, which affects their normal life.

The speed of Lu Chen and the others was not slow, and in less than five minutes, they did not find any danger along the way.

Even if they met one or two spirit beasts full of demonic energy, their own grade was not high, and they were directly killed by Lu Chen in a single thought.

Although the road was smooth, Lu Chen's brows gradually furrowed, and it was impossible for him to be so calm here.

On the contrary, in this case, Lu Chen's whole person became more vigilant, and the speed of moving forward gradually slowed down.

As for what Lu Chen was thinking, Hua Butterfly also understood that the true qi in her body began to run away, and she was also ready to go all the time.

After all, no one can say where a powerful existence will emerge from the next moment.

As the two became more vigilant, they also went deeper.

"Whew!"

In the dimly lit forest, several figures suddenly flashed by, and finally stopped on top of an ancient tree.

"Be careful, poisonous mist ......" Hua Butterfly's beautiful eyes swept around, and she sensed the poisonous gas for the first time.

Lu Chen had already sensed it, his brows furrowed slightly, and in that poisonous gas, there was a demonic aura.

"There is an anti-poison pill here, which has a certain effect on resisting these poisonous gases. A smile appeared on Hua Butterfly's vigilant face, and she handed the cyan pill in her hand to Lu Chen.

Lu Chen paused slightly, and immediately threw the pill into his mouth without the slightest hesitation.

Although with the blessing of the power of merit, Lu Chen was not afraid of those poisonous gases at all, but with the blessing of this elixir, it was better than nothing.

"This poisonous gas is really powerful!" Lu Chen became more vigilant, this poisonous gas was quite violent, if it was replaced by some cultivators with poor strength, he would only need to inhale a little and die.

In the midst of the gas, several bodies were lying on the ground, their bodies decomposing.

The level of decay was so severe that almost all that remained was the bones, and even the bones were reduced to dirt.

As Lu Chen continued to advance, the surrounding poisonous fog became thicker and thicker, but with the strength of Lu Chen and the others, these poisonous fogs were not enough to harm them.

But when he went deeper and deeper, Lu Chen suddenly found that this poisonous fog had not appeared for a long time.

There are still other strong people struggling here, and for the people here, it is their disaster.

"Boom!" When Lu Chen and the others frowned and shuttled through the poisonous mist, not far ahead, an extremely violent fluctuation of true qi suddenly came.

Feeling this fluctuation, Lu Chen's eyebrows immediately raised, and he immediately slowed down.

He stared at a clearing in front of him, where a blackened corpse had just fallen, and the face of this corpse was full of fear and regret.

Judging from this residual breath, this unlucky guy is actually a genuine low-grade powerhouse.

Unexpectedly, with the strength of this low-grade powerhouse, he couldn't stand the poisonous fog here.

Lu Chen turned his head to look at the flower butterfly, and saw that her current condition was okay, and she was still within the range of resistance to this black fog.

And the flower butterfly doesn't seem to feel much pressure, this girl from the demon world is indeed not as simple as it seems on the surface.

"The poisonous mist here is a bit strange, and this rank is casually killed like this here......" Hua Butterfly muttered with a deep groan on her face.

Lu Chen nodded, and in the process of continuing to move forward, his face suddenly turned gloomy.

The black mist around them suddenly swept towards their location, quickly wrapping around their bodies.

At this moment, the flower butterfly just wanted to make a move, but found that around her body, she didn't know when a purple flame appeared.

These purple flames formed a flame barrier around him.

When this high temperature spread, the poisonous mist seemed to be frightened, and it retreated sharply again and again, never daring to set foot within ten meters of Lu Chen's two people.

What kind of flame is this?

At this moment, Hua Butterfly's eyes were full of shock, and she had no way to judge what kind of flame this was for a while, exuding such domineering power.

"Follow me!" Lu Chen raised the spirit of twelve points, and said in a deep voice to the flower butterfly.

Hua Butterfly didn't say much, and immediately nodded and followed Lu Chen's footsteps.

In the forest filled with poisonous gas, a terrible scream was heard from time to time, and many cultivators here were all devastated by this poisonous gas, and were in an extremely gloomy atmosphere.

"Whew!"

In the midst of this thick poisonous gas, a sound of breaking wind sounded, and a faint fire appeared.

When the light of the fire suddenly appeared, the black mist in the surrounding forest, as if frightened, took the initiative to retreat and make way for an empty road.

"Awesome, what kind of flame is this?" Hua Butterfly looked at the road ahead of her that automatically split away, and praised Lu Chen, and then couldn't help but ask.

For this purple flame, the flower butterfly is very curious.

For the surprise of the flower butterfly, Lu Chen just said lightly: "Purple Thunder Spiritual Fire!" is not powerful, it is just restrained, these black mist belong to the power of yin and cold." ”

"And this purple thunder spiritual fire belongs to the most yang and fierce thing, and it is perfect to deal with these black fogs. ”
