The Burial Tower of Immortals buries the heavens, the earth, and all the immortals.

The Immortal Puppet Bright Ancestor himself did not reply, but instead slashed at the target with his sword.

Xiao Biyu dared not be negligent and hurriedly raised her fist to meet the attack.

The grand battle can be resumed once again.

This time, it was Xiao Biyu's turn to be at a disadvantage!

Moreover, the Immortal Puppet Bright Ancestor himself employed a fighting style of exchanging injuries for injuries, or even risking his life for his life, and Xiao Biyu was soon covered in wounds.

"Senior, I don't care who you are, and I won't ask why you're helping this young man. I just want to remind you that I come from Jiuji Mountain, and I'm the Third Elder of Jiuji Mountain. When you're out in the world, I have a background and powerful backers!"

"If you dare kill me, you'll be locked in a lifelong feud with the entire Nine Extremes Mountain. Of course, if you turn and leave now, I can forgive and forget, and I might even offer you some incredible benefits."

Seeing that they were outmatched, Xiao Biyu resorted to both coercion and enticement.

Of course, she was just talking to a brick wall again!

The Immortal Puppet, the Radiant Ancestor, completely ignored her, and his attacks with the long sword became even more ferocious.

"Fine, fine, you forced me to use my ultimate move!"

Xiao Biyu gritted her teeth, clearly determined to go all out.

However, the next moment, she suddenly went at full speed and flashed to Xiuer's side.

After that, the domineering power within her body was released uncontrollably, like a river bursting its banks.

And amidst the lightning and thunder, it enveloped her and Xiuer.

"Is this the domain?"

Qin Changye frowned and hurriedly stopped the Immortal Puppet Bright Ancestor, who was about to break through the domain.

Once the domain is destroyed, Xiao Biyu, who is inside the domain, will naturally suffer a backlash and be severely injured.

However, Xiuer, who is also in the same domain, will also be affected and face mortal danger.

Under normal circumstances, it would be impossible for Xiao Biyu to create a domain amidst lightning and thunder, and also to envelop Xiu'er within it.

But coincidentally, both she and Xiuer possessed the domineering attributes of the Overlord Body, which allowed them to activate their Overlord Body domains so easily and quickly.

"What do we do next?"

Having consumed a large amount of healing pills, Ren Pingsheng and the others had mostly recovered. Seeing Xiu'er trapped in the domain, they couldn't help but worry.

"From now on, we have no choice but to trust Xiuer!"

Qin Changye remained calm.

Normally speaking, Xiu'er, whose cultivation is still one step away from the Emperor Martial Realm, would have absolutely no chance against Xiao Biyu, who has reached the Half-Saint Realm, and would not even be able to withstand a single blow.

However, Xiao Biyu was severely injured in the battle just now, and her strength was greatly reduced.

Moreover, she spared no effort in activating her Overlord Body Domain and even pulled Xiu'er into it, all in order to conquer Xiu'er in terms of Overlord Body.

This falls into Xiuer's area of ​​expertise.

After all, when it comes to invincible bodies, Xiu'er's awakened Nine Tribulations Invincible Body is far superior to Xiao Biyu's unknown invincible body.

In fact, Qin Changye's guess was correct.

Within the domain of the Overlord Body.

"I never expected that your awakened Overlord Body would be even more extraordinary than I anticipated. Even within the Overlord Body Domain I created, and with my Devouring Overlord Body activated, absorbing the essence within your Overlord Body to further enhance my Devouring Overlord Body's level won't be a simple matter!"

Despite her shock, Xiao Biyu showed no sign of distress, only even greater joy.

The more powerful Xiu'er's invincible body is, the greater the enhancement effect of her devouring invincible body will be after it is absorbed.

As her Devouring Body strengthens, her cultivation level and combat power will also increase.

In this way, she could leave the Overlord's Domain and kill the Immortal Puppet Bright Ancestor who was waiting outside.

Compared to Xiao Biyu's determination, Xiu'er's expression was somewhat solemn.

She was very confident that her Nine Tribulations Overlord Body far surpassed Xiao Biyu's Devouring Overlord Body.

Unfortunately, her Nine Tribulations Body only reached the fourth tribulation, far from being fully mastered, let alone at its peak.

Soon, judging from the fact that her Overlord Body power was being slowly devoured, it was clear that hers was only the Nine Tribulations Overlord Body at the fourth stage of its power. Compared to Xiao Biyu's Devouring Overlord Body, which had already reached its peak, it was still slightly inferior.

"There is only one way to reverse this situation where the power of the Overlord is being continuously devoured, and that is to try to activate the Fifth Tribulation."

Xiuer was very confident that if the fifth tribulation was successfully activated, her own domineering power would not only not be further devoured, but might even devour Xiao Biyu's domineering power in return.

At that time, the balance of power will shift!

With her current physical strength, it's uncertain whether she can withstand the terrifying heavenly lightning that is destined to strike when she initiates the fifth tribulation!

"Let's take a gamble. Even if we're killed by the heavenly lightning of the fifth tribulation, it's better than having our domineering power slowly drained within this Overlord Body Domain."

Xiuer was also an impatient person, so she immediately opened her spatial ring and took out a drop of essence blood.

This drop of essence blood came from the Black Eagle King with whom she had signed a human-beast contract.

This is the essence blood of a level 5 peak demon beast with kingly bloodline!

Xiuer gritted her teeth and swallowed it without hesitation.

The moment the essence blood entered her abdomen, Xiu'er's body trembled violently, and the Nine Tribulations Overlord Body within her body was instantly activated, beginning to rapidly refine this drop of essence blood.

In an instant, the clear sky above the Overlord's Domain vanished, and the world changed color.

A golden beam of light shot upwards from Xiu'er's body, piercing through the Overlord's Domain, and quickly spread out a dazzling golden sea of ​​clouds in the sky.

Within this golden sea of ​​clouds, nine bolts of lightning could be faintly seen suspended above.

The first, second, third, and fourth bolts of lightning have already lit up.

At this moment, the fifth bolt of lightning also began to light up rapidly, its light dazzling and bright. Not only did it dazzle Xiao Biyu's eyes inside the Overlord's Domain, but it also dazzled Qin Changye and the others outside the Overlord's Domain.

"Xiuer is preparing to begin her fifth tribulation!"

Qin Changye had actually guessed that Xiu'er would take this path when facing Xiao Biyu in the Overlord Body Domain.

However, when Xiuer actually embarked on this path, she couldn't help but feel a little worried.

It's been too long since the fourth tribulation was last activated. I wonder if Xiu'er can withstand activating the fifth tribulation now?

Soon, the fifth bolt of lightning, unprecedentedly dazzling and containing unprecedentedly terrifying energy, roared down from the sky, carrying almost world-destroying power.

Within the Overlord's Domain, Xiu'er charged directly at Xiao Biyu, who was still in a daze.

Boom boom boom...

Before Xiao Biyu could try to dodge, the lightning bolt struck Xiu'er hard.

Naturally, Xiao Biyu, who was very close to Xiuer, was also affected.

The deafening roar lasted for more than a hundred breaths before finally ending, leaving one wanting more.

Xiuer finally managed to pull through.

Despite having multiple wounds on his body, many of which were quite serious.

"Judging from the sheer power of the lightning you summoned earlier, I thought it would be incredibly destructive. But it seems it's nothing special!"

Compared to Xiuer, Xiao Biyu withstood the aftershocks of the thunder almost unscathed.

After all, her cultivation had reached the semi-saint realm, and within this domineering body domain, her already extremely abnormal physical strength received a significant additional boost.

However, her expression changed drastically very quickly.
