Li Qing reacted extremely quickly, and the moment the Yin Evil Divine Thunder was thrown out, he had already avoided it early, although he would inevitably suffer some aftermath, but there was basically no damage.

As for the black fog that was blown out, it obscured the vision and was filled with an eerie aura, which should be some extremely lethal harmful gases, of course Li Qing didn't dare to touch them easily.

Although he has the body of a fairy spirit and is not afraid of many evil techniques, it does not mean that he will be arrogant and empty-sighted, otherwise sooner or later he will capsize in the gutter.

The direction of Li Qing's dodge was towards the gate, faintly blocking the only exit in this hall, making it impossible for Mr. Oniyi to escape.

Most of the area in front is shrouded in black fog, making it impossible to see the situation inside, I don't know what kind of conspiracy Mr. Onichi is doing in the fog, but as long as he guards this exit, he is basically invincible.

Li Qing stood there quietly, watching the black fog in front of him gradually fade. After a long time, the black fog finally dissipated, revealing the situation inside.

When I looked closely, Mr. Onichi was gone!

"How is this possible?" Li Qing was stunned for a moment, and couldn't help but wipe his eyes, and looked around, could it be that there was no other exit here?

He carefully observed for a while, the main hall was so big, he could see it clearly at a glance, and he didn't find any exit to escape, it was a completely enclosed place.

There is no aura of Mr. Onichi in the darkness, and it is obviously not a secret technique to hide.

"Where did you go? What the hell, a good person disappeared out of thin air!"

He searched in the main hall for a long time, but there was still no trace of Mr. Onichi. It was so weird that he was a little confused.

Could it be that this person slipped out of the gate under his nose?, but it was impossible to think about, he kept staring, unless Mr. Onichi would be invisible.

Suddenly, his heart moved, and he set his eyes on the black entrance of the dark hole connected to the earth fire under the Sun Moon Pill Furnace.

"Could it be...... Did he get into the mouth of this earth fire cave?" Li Qing guessed in his heart that there seemed to be no other possibility than this method!

It is impossible for a person to disappear out of thin air, and Mr. Onichi is very likely to have escaped from this earthfire passage to the underground. This man was so cunning that he could think of using such a method to escape, and who would have thought of burrowing into a burning hole?

Now that his traces have been discovered, this person can no longer be allowed to escape, Li Qing immediately made a decision and immediately jumped into this dark earth fire cave.

The entrance to the cave is not large, only allowing one or two people to pass through, but once inside, the passage is very wide, diagonally downward, allowing people to walk upright in it.

The stone wall is covered with some red lines, and it should be arranged with a super large array that hooks the earth fire, but at this time, the large array has not been activated, so there should be no problem.

Li Qing lit a torch, illuminated the darkness, and walked forward.

Looking down, he found a row of footprints from the ground, which should have been left not long ago, which further confirmed his suspicion that Mr. Kiichi had indeed escaped from here.

There was some heat in the passage, and waves of heat came to his face, which made Li Qing a little uneasy, in case there was a sudden fire gushing up from the depths of the ground, wouldn't it be a bad situation?

Under this sense of crisis, he couldn't help but speed up his pace, wanting to catch up with Mr. Kiichi and kill him to end the matter.

The further he walked inside, the hotter the air became, and his forehead was slightly sweaty, and Li Qing could only hold up the True Yuan shield to isolate the heat. At first glance, the passage is a circular passage that curves downward, very long, silent, dark, and unfathomable.

I don't know how long I walked, but it seemed that after walking through this hot area, the temperature suddenly began to slowly drop again, and soon reached a normal temperature.

However, to Li Qing's surprise, the temperature kept dropping and did not stop. The further you go, the cooler it gets, and it quickly turns into a bone-chilling cold, and layers of ice form on the ground.

From extreme heat to extreme cold, the two extremes switched, which caught Li Qing off guard. This place is just a little quirky.

After walking further inside, the temperature inside the passage began to slowly rise again, and finally it became very hot. I think I left the cold area and entered the hot area.

The rest of the distance goes on and on, hot and cold.

It seems that every once in a while, the temperature changes, as if there are two sources of ice and fire affecting the temperature beneath the earth. Li Qing spiraled down the passage, and the temperature he felt when he passed through these two sources of ice and fire would be different.

"Hot and cold, yin and yang...... I know, under this underground, this passage should be a swirl-shaped circular channel, just like a huge yin-yang fish, the two sources of cold and heat are located above the yang and yin points of this yin-yang fish, intersecting with each other, forming a mysterious array!" Li Qing guessed.

With such a huge and vast underground array, I don't know what the Yin Yang Demon Emperor built it for.

This passage is very long, after all, it is a swirling circular passage, which pushes downward in a circle from the outside to the inside, until it reaches the deepest part of the earth before stopping.

Mr. Kiichi should be not far ahead, and there are very clear footprints on the ground. This person's speed is not slow, he has been down so long earlier than Li Qing, I am afraid it will not be so easy to catch up.

In this way, they have been chasing for a long time, and the distance between the two sides has gradually narrowed.

Li Qing could feel that the aura in the air gradually became thicker, and the scope of this underground passage became larger and larger, several zhang wide, feeling like an estuary, about to reach the wide sea.

He knew the end was coming.

After continuing to advance for a while, he finally reached the deepest part of the earth, and suddenly a huge cave appeared in front of him.

I took a deep breath and felt that the aura here was too strong!

With such a strong aura, there is only one possibility for this situation, and that is...... This is the center of the terrain of Wanchuan Guihai, a real place where spiritual energy gathers!

Unexpectedly, chasing Mr. Oniichi, he actually came to such a magical place, hidden deep underground, and if it wasn't for this person to lead the way, he wouldn't have been able to find this place at all.

In this huge cave sky, there are even spirit stones condensed around, which is simply a small spirit stone vein.

Once here, there is basically no way to escape. There was a dark shadow in front of him, and it was Mr. Oniichi.

"Mr. Ghost One, don't run away anymore, there's no way out here!" Li Qing stepped forward.

Mr. Onichi didn't answer, but just swept forward, and the black shadow flashed, and he turned a corner.

"Hey, there's still a place to go in the back?"

Li Qing made a voice curiously, and immediately stepped out and chased after him. Turning the corner and looking closely, there is a small space filled with misty fog.

These mist are all transformed by aura!
