"What is this black gas?" Wu Zetian's face flickered, as if he had thought of something, but he didn't dare to believe it.

It was Zhang Jueyuan's words that made her frown.

"What a rich demonic aura!"

Zhang Jueyuan pinched a trace of residual black qi in his palm and sensed it carefully, and the black qi struggled desperately, but he couldn't break free from the old Taoist's control.

"Is it really demonic energy?" Wu Zetian was overjoyed.

This black qi does not have the nature of the demonic qi that is cultivated by ordinary demon sects, or it is poisonous, or charming, or treacherous, or cruel.

But Wu Zetian had seen it in the Demon Gate classics, the real top-level demonic qi was like this, there was no other miscellaneous nature, it was pure and did not contain the slightest impurities.

This kind of demonic energy is actually very similar to Lucifer's holy light, both are pure enough to purify (defile) everything, devour, assimilate and tolerate, but they are just two extremes.

The saints of the year, Jesus and Rahu, were a pair of mortal enemies, and they would fight whenever they met each other, if nothing else, just because of their natural restraints. In ancient times, these two people basically hated each other, either they didn't meet, or they accidentally bumped into each other.

"If it's really that kind of pure demonic qi, does there exist a Demon Gate predecessor here, or has it existed recently? I don't know if this will be my Wu Zetian's chance!"

"Your Majesty, should we go in!"

Guo Fu's voice interrupted her contemplation, and Wu Zetian looked up to see that a large hall was already in front of him.

This hall is extremely wide, and the fighting platform in the middle has a radius of several hundred zhang, which does not count the side hall and the apse.

However, the wider it became, the more empty it became, because there were no other items in it except for the fighting platform that was slightly above the ground, and a crisp echo could be heard after a few gentle steps.

More than 1,000 people entered the main hall, occupying only a small area, which seemed incomparably small.

Wu Zetian ordered the soldiers to stand in formation, and he and Zhang Jueyuan and Guo Fu went around to investigate.

The three of them meticulously surveyed every corner of the hall, while the warriors stood silently, and a thousand of them did not say a word.

When he was concentrating, he suddenly heard a crisp sound from the side hall, as if someone had taken a heavy step inside.

Zhang Jueyuan, who was bending down to inspect the stone platform, suddenly straightened up, and a blue light flew out of his body, firmly protecting Wu Zetian.

And Guo Fu is figure flashed and flew to the side hall.

To her surprise, there was nothing in the side hall, it was also empty, just like in the main hall, and after the crisp sound, no sound came from the side hall, as if it had just been an auditory hallucination.

Guo Fu did not give up, carefully floating in the side hall, and from time to time knocked on the blue bricks on the ground and the walls on both sides with his hands, wanting to find the secret room or something.

But she was still disappointed, the walls and floor were solid, and there was no trace of the secret room.

There was a sound of footsteps behind him, but it was Wu Zetian who also walked in under the support of Zhang Jueyuan.

"Did you find anything?"

Zhang Jueyuan spoke first.

Seeing Guo Fu shaking his head, he frowned, what could have escaped the king's search?

At this time, Wu Zetian, who had been standing behind Zhang Jueyuan, suddenly pointed to the corner of the main hall and said, "Why is there a tree in the main hall?"

Zhang Jueyuan and Guo Fu turned their eyes away, and saw a small black tree standing there alone in the corner, looking so inconspicuous in the dark hall.

"Could it be that the footsteps just now came from this tree?"

Doubts popped up in the minds of several people at the same time, and they saw that there was nothing else suspicious around them.

"I'll take a look!" Guo Fu said and walked over, the branches of the small tree were scarce and there were no leaves, let alone the breath of life, it looked like a dead thing. It's no wonder that Guo Fu ignored it before.

She approached and reached out to the branch gently, and was about to touch it, when the small black tree suddenly shook slightly.

"Huh?"

Wu Zetian and Zhang Jueyuan, who had been paying attention to this place, spoke at the same time.

This tree is really alive!

A pair of cold eyes suddenly opened on the trunk of the small black tree, and the branches wrapped around Guo Fu for a long time, and a cold breath hit first.

Guo Fu remained vigilant, and a layer of red true yuan appeared on his outstretched right hand, and a scorching line of fire "flowed" out of his two fingers in the middle of the food, and rolled towards the branches of the small black tree.

The red light flickered, and the branches fell to the ground.

As soon as the thin black branches touched the ground, they turned into a puddle of blood, its color was dark, and it emitted white smoke.

"Kui Qi?" Zhang Jueyuan blurted out.

"What is it?" Wu Zetian had never heard of this name.

"Kui Qi is a branch of the demon clan of the Dryad, they seem to be plants but are actually animals, they like to eat fresh flesh and blood, but they are filthy and poisonous. Zhang Jueyuan explained.

Wu Zetian's question was even deeper, "The Dryad Clan? I never knew that there was such a branch in the Demon Clan. ”

Zhang Jueyuan nodded, "It's not surprising that this clan was wiped out long before the saints disappeared in the ancient period. I have also seen incomplete records in some of the incomplete classics in Wudang's collection. ”

"I see!"

However, it was said that Guo Fu broke one of the branches of the dryad and turned it into blood, and the black gas on the main trunk of the dryad flashed, and immediately another one grew, and it seemed that it was not affected at all.

Its feet were pulled out of the ground, shaped like duck webs, and rushed towards Guo Fu with a click.

Black gas swirled out from the main trunk, transforming into black flowers and fruits, constantly attacking Guo Fu, and slender branches also meandered out of the trees and wrapped around him.

Guo Fu's skirt swayed, drifted back a few feet, and pinched the magic with both hands, and nine flame dragons sprouted out of thin air and circled around him, spitting red flames from his mouth, and burning those flowers and fruits into ashes.

The little black tree seemed to be a little frightened, and suddenly made a buzzing sound, and the black light flashed and sank to the ground.

"He'll run away!" Zhang Jueyuan reminded loudly.

Guo Fu chuckled, the jade hand closed slightly, and the ground suddenly turned into hot magma, the black dryad screamed and bounced, and a jade hand wrapped in flames reached out in mid-air and pinched it fiercely.

Guo Fu carried the tree demon to Wu Zetian and the others, threw it to the ground, and wrapped his whole body around a faint line of fire to prevent escape.

Zhang Jueyuan and Wu Zetian glanced at each other, and said tentatively: "Do you know how to speak human language?"

The yellow eyes of the dryad stared at him, and a muffled voice came from the trunk, "Squeak and buzz!"

Several people looked at each other, and they all shook their heads, and no one understood what he said!

The dryad cooed and squeaked again, and suddenly his eyes were cold, and he exploded with a "poof", and black blood splattered in all directions.

Zhang Jueyuan reacted the fastest, drew a circle with his right hand, and Tai Chi's true intention unfolded, collecting the scattered dirty blood, and then throwing it on the wall of the main hall.

With a "z", a large hole corroded into the wall.
