Deep underground, Yi Chen and the others had been walking for several hours, and in his judgment, it should have been night at this point in time, and it would not be much different from the middle of the night.

By now they had walked nearly five thousand meters downward, but that distance was still a drop in the bucket for the three-meter trail that appeared in front of them as far as the eye could see.

The surrounding air and environment had changed significantly, and the stuffiness and burning sensation in the air had become stronger and stronger, and even the shield of the Innate Realm peak cultivator had not been able to completely isolate it.

Faced with such a situation, cultivators in the late innate stage have already taken off their clothes in order to relieve the heat of their bodies.

These people are still mortal realm cultivators, and they don't have the strong flesh of the spirit realm powerhouse, this level of heat can already affect their physical body, and they can only rely on this way to minimize the damage to their physical body.

Perhaps due to the difference in terrain, their vision is no longer distorted, and they are completely in darkness.

The dim glow that emanated through the shield outside them, a gray mist formed entirely of gray dust enveloped them, floating and moving with their movements.

The further down they went, the thicker this gray mist became, and now it was dense enough to block their gaze, and with the eyes of the Turbidity Pill Realm, they could only see clearly within seven meters of themselves.

Not only that, but the gray mist seemed to have the ability to isolate sound, and it was only three meters away on the right side of Yi Chen, and the footsteps of the cultivators who were parallel to him came, and it was not as loud as before, and it was extremely dull.

Several Innate Realm cultivators in front of Yi Chen were already struggling, as if a pair of huge iron balls were tied to their feet, and they could only walk on the ground.

"No, if we continue like this, sooner or later we will die due to the exhaustion of our true qi, rather than this, it is better to fight with them", one of the innate late-stage cultivators who was walking let out a low sigh, full of determination and firmness.

A pair of bloodshot eyes turned behind him, and then fell into the fog in front of him, clenching his hands tightly.

The amount of True Qi and True Yuan spent to maintain one's own protection for a long time was very huge, and the light on the bodies of all the cultivators of the Innate Realm had already begun to flicker non-stop, approaching the level of darkness.

Even a few half-step Turbidity Pill realm cultivators around Yi Chen began to look uncomfortable, and their faces gradually became pale and weak, and if they continued like this, they might not last long.

Under this kind of physical and spiritual torture, Mo said that it was these cultivators, and even Yi Chen felt a trace of impatience.

"Brother, your idea is indeed good, but don't forget, their true qi has not been consumed much, do you think you can beat them?"

Another late-stage innate cultivator walking side by side beside this person sneered, and there was a feeling of helplessness.

"I can't beat them, but we have so many people here, I don't believe they can all stay, as long as I can hurt one of them at that time, it will be earned", gritted his teeth fiercely, this person's face was full of ruthlessness and unwillingness.

"That's right, I also support this, it's a big deal to die with them."

"Yes, I really don't believe they can leave us all, if it doesn't work, we'll run away."

The conversation between the two was very quiet, and there was a gray haze in the distance, and only a few people in front of and behind the two could be heard, which also caused their anger to vent.

Especially what the last person said, it made them even more impulsive.

The gray haze at the moment can affect the cultivator's vision, and the practitioner's perception is of no use in this environment, and they are in the best position in the group, which is undoubtedly a good opportunity for them.

As long as they seize this opportunity, they can not only break away from the control of the Invisible Gate, but also go down to the deepest depths before the Invisible Gate and the Qingyan Tower, and they will also have the opportunity to collect the Diyan liquid, and even take away that anti-heaven opportunity before the arrival of the two forces.

"Ah..... What's that!!"

However, just as they were discussing their desire to motivate the others, one of the people at the front of the group suddenly let out a shrill scream that even they could hear clearly.

Since they entered the air wall, there has been no danger until now, but with the lessons of the past, coupled with the actions of the invisible door and the Qingyan Tower, they have seen that there is a dangerous place in front of them.

In this vigilance, they are a flock of frightened birds, and even the slightest movement will make them feel like a great enemy.

All the scattered cultivators drew their weapons at the same time under this exclamation, and quickly swallowed the next pill, and at the same time urged the little true qi in their bodies to move, and their eyes were firmly fixed on the direction pointed by the screamer.

Staring at the ten breaths directly in front of the three-meter path, everyone's breathing sound was very low, and the killing intent in their eyes emerged.

However, they didn't see anything except the gray mist that was getting thicker and thicker, and even the cultivator who screamed was confused, and he was very puzzled and moved the gray mist in front of him with his hands.

"What the hell is called!!".

"It's a joke like this at this time."

"You give me to be careful, if there is a next time, I will kill you first."

There was no other situation for a long time, and the others couldn't help but look at him angrily and scolded him one after another.

However, these cultivators didn't notice that after they shifted their gaze, the gray mist that had been static suddenly flowed in one direction, and then a strangely shaped blurred figure flashed through the gray mist before disappearing.

"No..... I didn't lie to you, I did see something before, although it was vague, but I can be sure that it must not be human."

In the face of everyone's accusations, the man's face was bloodshot, and then he let out a scream.

At the same time, in order to prove that he was not mistaken, this person also deliberately drew the long sword in his hand and quickly stabbed several swords into the gray mist.

But in the process of his forward stabbing, his face became more and more pale, especially when he withdrew the long sword and saw that there was only a thick layer of gray dust clinging to the long sword, and his face was no longer a trace of blood.

"Remember, this is the first and last time".

"That's right, if there is a next time, I'll throw you down from here to see if you can survive."

There was another shout after shout from the crowd, and the man could only drop his weapon and let them speak.

At the same time, at the back of them, Liu Hong's steps forward from the invisible door suddenly paused, and his right hand couldn't help but quickly pinch a few times, and a little solemnity suddenly flashed between his eyebrows.

"What time is it?".

With a wave of his sleeves, Liu Hong suddenly asked out of thin air.

"Tell the deputy door master, we have been walking underground for nearly ten hours, and it should be almost late at night at this time", a person in front of Liu Hong hurriedly stepped forward to say.

Hearing the advice of his subordinates, his eyes fell on the figure of the loose cultivator in front of him, Liu Hong's brows furrowed a little tighter, and his face gradually revealed a trace of gloom.

Knowing the situation here, he naturally understood what this point in time meant, but in order to save his subordinates, he would let these participating cultivators as pathfinders.

It's just that it's really not appropriate to continue moving forward at this point in time, if he persists, maybe his subordinates will also lose a lot, which is really not good for the final battle.
