Han Xuenian didn't seem to hate Xiao Zhan that much, and after two seconds of silence, he spoke:

"The Chaos Treasure in my body has a natural perception of strange energy."

Han Xuenian stretched out his finger and pointed to the dark space deeper in front of him, and said expressionlessly:

"At the end of there, there's an aura that makes me feel horrible."

In fact, even if Han Xuenian didn't say it, Xiao Zhan vaguely felt the danger, and his expression became solemn.

Obviously, Han Xuenian was not a reckless person, and after a moment of contemplation, he asked indifferently: .

"Would you like to go and see it together?"

Xiao Zhan's figure flashed, appeared on the altar, and with a wave of his hand, the entire altar, along with the foundation below, was uprooted and included in the second-level world in his body.

When Han Xuenian saw this scene, a strange emotion flashed in his eyes.

Yes, he and Xiao Zhan are both geniuses among geniuses, and they both have Chaos Treasures, especially now that he has worshiped the Demon God as his teacher, he never thinks that he is better than Xiao Zhancha.

But according to what he knew, Xiao Zhan was also proficient in alchemy, refining weapons and formations, and could be called an all-rounder.

Even when he saw Xiao Zhan's information for the first time, he was full of admiration.

Seeing Xiao Zhan this time, he was even more jealous of Xiao Zhan.

Because Xiao Zhan, who is so versatile, his style of acting is still unpredictable, which gives him a huge sense of crisis.

If he really had to fight to the death with Xiao Zhan in the future, Han Xuenian would never dare to say that he would be able to win!

"Let's go," Xiao Zhan looked at the darkness ahead.

Han Xuenian didn't talk nonsense anymore, his figure flashed, and he rushed into the darkness, and Xiao Zhan quickly followed.

The two of them have a strong sense of perception, even in the dark.

I don't know how big this underground space is.

Two hours passed, and neither Xiao Zhan nor Han Xuenian rushed to the area where the terrifying aura was.

Suddenly, Xiao Zhan and Han Xuenian stopped at the same time, looking at the darkness ahead with expressionless faces.

The surrounding air seemed to become viscous at this moment, and a fishy smell slowly spread.

In the next moment, a pair of eyes glowing with a faint blue light slowly appeared in the darkness.

The eyes were as big as a millstone, and looking at Xiao Zhan and Han Xuenian was like looking at their prey.

A strong sense of oppression struck, making Xiao Zhan and Han Xuenian both look solemn.

Han Xuenian said coldly: "I don't know how many years this thing has been cultivating here, if you want to talk about strength, I'm afraid it is already comparable to the middle and late stage Demon Venerable, there are not many such powerful beasts."

Xiao Zhan didn't speak, but the momentum on his body continued to rise, and the black dragon spear was also held in his hand.

Han Xuenian's eyes lit up and asked, "Are you on or on me!"

Xiao Zhan glanced at Han Xuenian, nodded and replied, "You can go up."

Han Xuenian snorted coldly, his figure flashed, and he rushed towards the darkness.

In the next moment, a white light exploded, and the surrounding underground space was as bright as day.

Xiao Zhan also saw the true appearance of this fierce beast.

The beast was slender, like a huge black lizard, covered with black hard bone spurs, like a set of black armor, and its tail was covered with black, cold scales like blades.

On its head, there is also a sharp horn, which looks extremely hard, and there is a mouth full of sharp teeth, a black tongue, which is constantly swallowing, and dark blue eyes are staring at Han Xuenian.

Han Xuenian has just moved.

The demon beast flicked its tail and slammed it towards Han Xuenian.

Despite its size, it looks like a hill, but it is extremely fast.

So much so that Han Xuenian couldn't avoid this blow, and could only mobilize the energy of his whole body to form an energy barrier in front of him.

"Bang!"

The energy barrier exploded in an instant, turning into a strong wind that spread, bombarding the surrounding stone walls, making bursts of explosions.

Han Xuenian's body is even more down

Fly dozens of meters, but still land steadily.

Han Xuenian's expression suddenly became even colder.

With just this temptation, he knew that the combat power of this fierce beast was even stronger than he expected.

But Han Xuenian was not afraid at all, his figure flashed, and he took the initiative to attack this fierce beast again.

In the darkness, a faint blue light and white light flickered.

The deafening sound continued to sound, and the entire underground space seemed to collapse completely.

Xiao Zhan frowned, his figure flickered, and he began to arrange formations around him to strengthen this space.

Above the underground space, deep in the sea, there is a mountain range lying on the bottom of the sea.

At this time, the entire mountain range shook violently, and the surrounding sea water was constantly churning.

If you look closely, you will find that there are many houses and palaces made of stone in the mountains under the sea.

It is inhabited by a strange sea beast.

They looked like octopuses, but their bodies were covered with fine silver-white scales, and they were scurrying around in great panic.

In a palace.

An old man sits on a throne.

It's a giant octopus-like creature.

Feeling the vibration of the mountain range, a solemnity flashed in its eyes, and in the next moment, its body was wrapped in a layer of white light, and its upper body instantly turned into a humanoid old man, but the lower half of its body was still an octopus-like tentacle.

Its figure flashed, turned into a streamer, and soon appeared outside the mountains, closed its eyes and perceived, and immediately let out a strange moan from its mouth.

After a while, a series of figures appeared in front of it.

Like him, these creatures were in human form, and they were all sturdy men, burly in shape, with harpoon-like weapons in their hands.

The lower half of their bodies are still octopus-like tentacles.

The old man said coldly:

"I'm afraid something has happened to the forbidden land, I have to check it out immediately!"

As soon as he said this, the tentacles of the old man's lower body continued to twist, and the surrounding sea water instantly became turbulent.

In the next moment, a white light lit up in front of the old man.

The old man led a group of subordinates, and his figure flashed, and he got into the white light.

In the next moment, they appeared in the pitch-black underground space.

In front of them, there was a mountain of blue crystal, which could be faintly seen, and in the middle of this blue crystal peak, there was an ice-blue coffin sealed, and there was a faint figure inside.

The old man's face was solemn, he looked at the darkness in the distance, and said coldly:

"Whoever trespasses must die!"

After saying that, he immediately took his subordinates and flew towards the darkness at a very fast speed. bμν.

At this time, Xiao Zhan's formation had been arranged.

The aftermath of the battle between Han Xuenian and the demon beasts was all blocked in the formation, which did not let this underground space collapse.

Han Xuenian's methods are endless, even in the face of such a powerful beast, even if he falls into the disadvantage, he does not reveal much of his hole cards, and he is obviously still afraid of Xiao Zhan.

However, Han Xuenian is really strong, obviously at a disadvantage, but he can use all kinds of unexpected ways to fight.

Half an hour passed quickly.

Xiao Zhan suddenly frowned and said:

"I feel that other breaths are approaching, this beast is too strong, even if the two of us join forces and use all our means, I am afraid that we will not be able to kill it in a short time."
