"I didn't expect that there is a real mystery in it."

Mao Bi couldn't help but say as he watched Gu Zheng quicken his hands and feet to widen the gap little by little.

"Go over and take a look. We are looking for someone. If the other party knew, it would save a lot of time." After spending some time, Gu Zheng finally made a space in front of him that was big enough for them to enter.

Because Gu Zheng knew in his heart that if he walked from the inside out, the further forward he went, the greater the chance of encountering the enemy. The battlefield was almost fought around the perimeter, but now he can feel the defeat here.

The faster you can repair the formation spirit, the more confident you will be able to fight against the opponent when encountering danger.

The only thing that worried Gu Zheng was the Chaos Demon in that position and the heroic spirit that was caught in the opponent's air. He could only hope that the formation spirit could find a way, otherwise the three of them alone would have made them unable to match.

After walking through this passage, not long after, a strange smell came into my nose.

"Be careful ahead, it's poisonous." Even though the slightest touch up to this point had no effect on Gu Zheng, he still warned him.

"Then what should I do? I can't move forward. I can't block the poisonous mist with the treasure box on my back." Mobi who was following behind was shocked and stopped in place and stopped moving forward.

In this situation, it will have no problem facing a slight poisonous mist, but if it is more serious, it will not be able to protect the treasure box.

"Wait for me here. Wait until I give you the signal to come out, or I will come over to find you." Gu Zheng said immediately after hearing this.

Anyway, the opponent's combat power is negligible, it doesn't matter whether it comes or not.

Since the poisonous fog was coming, there must be a poisonous source ahead. After being prepared, Gu Zheng walked forward again. Not long after, a yellow light came in from the front.

Let Gu Zheng know that the exit is right in front of him, so he has to be more cautious.

Arriving outside where the last ray of light shined, Gu Zheng used a ray of consciousness to look inside. To his surprise, there was no danger inside and there was an empty hall.

After hesitating for a moment, Gu Zheng decided to go in first. If an enemy appeared at this location, wouldn't it be a target?

There were no traps in this exit. He walked out of it smoothly and then looked around carefully.

This hall hole is about the same size as the previous one, and also very high. There is a huge stone pillar in the middle, leading straight to the top.

On the surrounding walls, many golden ores were forcibly placed on them, and golden light emanated from them.

But the only difference is that in another corner, a thick green mist is lingering in it, and it can be vaguely seen that there is another passage inside, but I don't know where it leads.

"Heir, are you really here?" At this moment, a crisp sound of surprise came from the air.

"Who are you? Where are you?" Gu Zheng looked around, and finally his eyes were fixed on the blocked road.

The title of successor seems to be given by the people here to the owner of Yunhuang Sword, that is, Gu Zheng, a common name, as if everyone knows it. This is also information that those demon souls cannot know, so Gu Zheng knows it immediately

The other party must be from here, so he came here.

"I am Empress Yufei's medicine boy. When I came out a long time ago, I was trapped here by a demon and couldn't escape. I hope you can help me. I will be very grateful to you." The voice was full of hope and spoke to Gu.

Zheng said.

"How can I help you? Has this green mist trapped you?" Gu Zheng looked around, but there was nothing except the poisonous mist in front of him.

"This poisonous mist is caused by a demon soul. It is very powerful. You must not touch it. And the other party has something that can open this place. You just need to defeat the other party." The other party said quickly.

"The other party will come every few days. You have to be careful. The other party is best at poison gas, and even I can't completely cure it." The other party said with some worry.

"That's a bit troublesome. The situation outside is already very bad. I can't wait here for a few days. I'll see if I can break open by force first."

Gu Zheng originally wanted the other party to guide him to find Empress Yu Fei, but when he thought that the other party had been trapped here for a long time, and Empress Yu Fei seemed to have left her original place before, it goes without saying that she knew that she definitely did not know the other party's location, so he asked

It's also a useless question.

Since the other party is Empress Yu Fei's medicine boy, there must be some connection between them. After rescuing her, he can take them to find her, and then ask how to enter the Hall of Humans and Tigers. This is Gu Zheng's idea.

"Be careful. This poisonous mist is very overbearing. If you inhale it, it will turn into a puddle of pus in an instant." The medicine boy continued.

While paying attention to his surroundings, Gu Zheng stepped forward and looked at the poisonous mist that was only a foot away from him.

The green mist above seemed to be alive. Wisps of it kept emerging from it, transforming into various forms, wandering around the outside and then diving in.

Even on the surface of Guzheng, I don't know when, a light green mist has covered it, but it is blocked by a layer of golden light, making it impossible to break in.

Feeling the flow of mana in his body, Gu Zheng frowned, and a flame suddenly appeared in his palm. The surrounding poisonous mist quickly dissipated under the expulsion of the flame.

However, it is only a poisonous mist within a certain range. It can still be felt in the invisible space and is diffused everywhere. If it is carelessly exposed in the air, there will not be many consequences.

The flame in his hand continued to grow, and soon it was as big as a head. With a flick of his wrist, the fireball flew towards the poisonous mist in front of him.

As soon as they entered the range of the poisonous mist, the originally flowing poisonous gases merged from all directions, but once they got closer, they were directly evaporated by the scorching heat, making it impossible to get close.

However, when the fireball entered the true range of the poisonous mist, countless poisonous mist rushed over one after another, just like water extinguishing fire. In less than three breaths, the fireball disappeared from the sky, and the poisonous mist showed no signs of reducing.

.

His brows deepened and tightened. The short contact allowed him to roughly know something was different inside. If he wanted to disperse the poisonous mist, it was obvious that conventional methods would not work.

Being able to overwhelm the opponent's head with your own hands means you have this.

With another flash in his hand, a white flame the size of a fist once again condensed out of the air.

Even though it was twice as small as before, as soon as the white flame appeared, the surrounding poisonous mist dissipated instantly.

As the poisonous mist slowly passed in front of him again, the originally relatively calm poisonous mist became even more like boiling water.

Water can extinguish fire, and fire can extinguish water.

The poisonous mist wanted to submerge the flames again with its special properties like before, but when it was only half the distance away, the poisonous mist was directly burned away by the hotter flames.

Although this white flame does not look as blazing as the previous fireball, its power has been increased by more than ten times.

When the white flame stopped steadily at the door of the passage, it had not consumed half of it, but the poisonous mist at the door had been burned away by one-tenth, and it was still reducing at an extremely fast speed.

I'm afraid it only takes a while for all this poisonous mist to be wiped out.

Gu Zheng finally showed a smile on his face, then turned around and walked back, as if the overall situation was decided.

But when he just took a step forward, a black lightning suddenly appeared in the sky, and struck Gu Zheng's head with lightning speed, hitting him instantly.

A large black light burst out from Gu Zheng's body, and his body looked more like he had been severely injured. His whole body was directly hit against the wall beside him, hit it heavily, and then fell to the ground.

With a soft cry, a monster appeared from the sky and flew downwards. In mid-air, a green light flew out of the opponent's mouth and rushed towards the white flames surrounded by poisonous mist.

The green light flashed again as it approached, and turned into a small crystal green cover, wrapping the white flame in it, trapping it firmly in place.

Without the interference of the white flames, the small gap that had just been formed was once again covered by the poisonous mist. However, upon closer inspection, it was found that it was much thinner.

The monster's figure just paused in the air. After dealing with Bai Yan, a fierce light flashed in its eyes, and the wings behind it crawled up, speeding towards the figure below who had just climbed up.

As soon as the opponent stood up, his figure was already coming like the wind, and the two sharp claws under his feet were already grabbing at the chest in front of him.

There was a flash of cold light in the air, and a dagger slashed towards the figure's head.

A two-pronged approach, one fatal blow.

The monster looked at the figure in front of him with a horrified look in his eyes. He retreated and tried to lift the weapon in his hand to block the dagger.

Unfortunately, it was too late. There was not much space in the hall itself. The other party had just moved and reached the outside of the wall. It was also a crack in the corner of the wall. There was no way to escape.

Perhaps because there was no hope of escape, the opponent gave up blocking with his hands and looked at the attack coming towards him, but there was a hint of sneer on his face, which made the monster a little confused.

But it was too late, the sharp claws had already penetrated the opponent's chest, and the dagger had even scratched the opponent's neck.

"boom"

A ball of golden light exploded in front of his eyes, and the figure in front of him turned out to be just a phantom. This frightened the monster so much that it flapped its wings tightly and was about to take off into the air, but it was a little too late.

Behind it, the whistling sound suddenly became louder.

Gu Zheng appeared behind it, raised his huge fist and hit one of its wings.

Under his deliberate sneak attack, even if the other party noticed it at the last moment, it was still too late.

This place is the place I specially prepared for it. There is no room for detours at all, so I can only deal with this attack of my own.

"boom"

Gu Zheng was about to hit the edge of the opponent's wing without any mistake. He only heard a crisp "click" sound. Needless to say, the opponent's wing broke directly. The whole person flew out and hit the wall in front of him.

This time it is its turn to experience the pain just now.

However, even if the opponent suffered a heavy blow, he could forcefully adjust his figure at the critical moment.

The entire figure turned sideways and stood upright in the air for an instant. Then without looking at Gu Zheng, he suddenly flapped his only remaining wing. A stream of air burst out from his body, and the entire figure flew into the air in an instant.

Gu Zheng, who was following behind, had no time to block the opponent's escape, but he still punched the opponent's back.

There was an explosion throughout the hall, and a horrifying wave rushed towards the monster in the sky at high speed. When the monster rose into the air and wanted to turn, it grazed one of the opponent's sharp claws.

With an even more painful cry, the claws exploded in the air, leaving behind a cloud of blood mist, but the opponent was completely out of Gu Zheng's pursuit.

Gu Zheng looked up at the monster above. He felt a vague sense of being watched when he came in, so he deliberately lured the monster out. The monster was indeed fooled.

Look carefully at the monster above. It's not a monster, but a bird monster.

His whole body is golden and his eyes are piercing, like a huge eagle, but his body is very thin and he has a black crown on his head, which makes him look majestic.

Under the unbroken wings, a short sword is embedded in the feathers, ready to dance according to its wishes at any time.

However, at this time, the opponent looked very embarrassed. The place where the sharp claws exploded was still dripping with blood. One wing was drooping, and the other was slowly instigating in the air. Under such a sneak attack by Gu Zheng

, was directly hit hard.

The strange bird looked at Gu Zheng fiercely, full of resentment, and wanted to tear him alive. However, it also knew that it was no match for him at this time. After remembering Gu Zheng's appearance, it turned around and flew upward, trying to
To be continued...
