The inside of the Aoki coffin was empty, except for a single skull.

There were no bones, and the skull was lying alone in the green wood coffin, but the skull was black throughout, as black as ink, and it was even more profound.

The skull exudes a deep and vicissitudes of life, and there is a trace of decay, as if it has gone through thousands of years.

"This is the skull of the Ancient Demon Lord!"

Zhang Jian felt the breath of the Ancient Demon Lord from this skull, obviously this was the skull of the Ancient Demon Lord, and the remnant soul of the Ancient Demon Lord had always been stored on it.

But there was only one skull here, and what about the other dry bones of the Ancient Demon Lord, had they been eroded and decayed by the years, or was there another place to bury them?

Zhang Jian was puzzled, but obviously he couldn't get an answer at the moment.

"I've seen pale dry bones, I've also seen copper-colored dry bones and silver dry bones, according to my speculation, there should be golden dry bones, why is the skull of the Ancient Demon Lord black, is it because he is special, or is there something wrong with my speculation?"

Zhang Jian was puzzled in his heart, looked at the black skull in the Aoki coffin, and fell into deep thought.

Airplanes!

At this moment, the black skull suddenly bloomed with light, melted instantly, and in Zhang Jian's surprised gaze, it turned into a drop of black water, the black crystal was shiny, like an elixir, but it was extremely soft.

Eat it to strengthen your muscles and bones!

Suddenly, such a thought appeared in Zhang Jian's mind, and the appearance of this thought made Zhang Jian startled, but he quickly reacted.

"This should be the remnant of the Ancient Demon Lord, no matter what, this skull can make the remnant of the Ancient Demon Monarch survive to this day, it must have something extraordinary. ”

Zhang Jian muttered, and suddenly he grabbed this drop of black water, the black water was neither lukewarm nor hot, like a pill and a liquid, extremely peculiar.

"Perhaps, this is an opportunity for me to break through!"

Zhang Jian's eyes were bright, he was the strength of the Transformation Realm Nine at the moment, but such strength was not enough in this ancient battlefield, and he didn't even dare to set foot in the central area easily.

But he had to go, because there was the other half of the demon slaying sword in the central area, and he had to get it, otherwise Jian Ling's life would be in danger, and there was also a Bodhi Zi there, which was also something he would get.

Originally, Zhang Jian's plan was to improve his strength in the peripheral areas first, but now there is such an opportunity.

As long as he breaks through the sublimation realm, the supreme divine body will also be promoted to the fourth layer and obtain the fourth divine power, all of which add up, for Zhang Jian, his strength will increase exponentially.

Therefore, even though this drop of black water is full of danger and unknown, Zhang Jian is not willing to give up, he must seize this opportunity.

Besides, martial arts is already full of ups and downs, if you don't even dare to set foot in this danger, how can you talk about climbing to the peak of martial arts and going to take revenge on your former enemies.

Therefore, Zhang Jian swallowed the black water in his mouth without hesitation.

The entrance of the black water suddenly turned into a boiling hot stream flowing down the meridians to the limbs and hundreds of remains.

There are two hundred and six bones in the human body, and the heat flow of the black water is directed towards these bones, to quench the bones, make them harder and stronger.

A tearing pain came from all over his body, making Zhang Jian's heart tense, and he knew that the black water was starting to work.

This black water is the essence of the skull of the Ancient Demon Lord, containing extremely majestic energy, and at this moment, it touches Zhang Jian's bones, like a piece of red-hot iron entering cold water to quench.

The pain of the tear gradually became intense, and Zhang Jian had the illusion that someone was hammering his bones with a heavy hammer, trying to smash his bones to pieces.

This tearing pain was like a tide, wave after wave, wave after wave, wave after wave, making Zhang Jian clench his fists and bite his lips tightly, and in an instant, there was red blood oozing out.

The black water entered the bones, refining Zhang Jian's bones, and waves of pain came surgingly, and later, even Zhang Jian couldn't bear this pain.

"Ahh

A hoarse roar came out of Zhang Jian's mouth, this kind of pain could not be experienced at all, let alone described in words.

"Brother Zhang!"

Jing Ran on the side saw that Zhang Jian was hideous, roaring and terrifying, and the worry in his heart was even heavier, so he couldn't help but speak, but he couldn't help, so he could only watch.

The snake girl on the side was even stronger, so she could feel that Zhang Jian was transforming, but she felt a strong and palpitating aura from Zhang Jian's body, which made her tremble and panic.

"Rush over, you can break through the sublimation realm, you must rush over, rush for me!"

Zhang Jian gritted his teeth and insisted, his firm belief put the pain aside, and no one could stop his determination to become stronger.

"Shhhh

A terrible voice sounded from Zhang Jian's mouth, his whole body was drenched in cold sweat, his face was hideous, he could no longer stand up, and collapsed to the ground, but the breath emanating from him at this moment was getting stronger and stronger, like the last moment of breaking a cocoon butterfly.

"Break it for me!"

The green tendons on Zhang Jian's neck burst out, and he looked extremely frightened, but he let out a deafening roar from the sky, and suddenly an extremely powerful aura burst out from his body, forming a violent wind that swept through the entire main tomb.

The wind was too strong for Jing Ran to resist, and the snake queen revealed her body and protected Jing Ran in it, but she was also prostrate on the ground and didn't dare to resist.

What kind of terrifying aura is this, is this really something that a Transformation Realm martial artist can burst out?

The wind became stronger and stronger, triggering the spirit array here, and the spirit array swayed for a while, like a flat boat in a violent rainstorm.

"Oh no, this place is going to collapse!"

Suddenly, a look of surprise flashed in the eyes of the snake queen, she hurriedly rolled up Jing Ran and Ah Niu, followed the passage that came in, and quickly rushed out, as for Zhang Jian, she believed that Zhang Jian would never die at this moment.

Thundered!

The spirit array collapsed, and the entire skull tomb shook violently, and large pieces of falling rocks fell, and the main tomb was in a mess, only Zhang Jian in the center exuded more and more blazing golden rays, which flew out of his body, penetrated the flesh and blood, and illuminated the entire main tomb.

Falling rocks roared down, and the entire skeleton tomb completely collapsed in a very short period of time, outside the skeleton tomb, the snake Ji rushed out with Jing Ran and Ah Niu dangerously and dangerously, looking back at the skeleton tomb that had collapsed into ruins, and couldn't help but feel afraid for a while.

"Brother Zhang!"

Jing Ran screamed, desperately trying to go back to find Zhang Jian, but was dragged by the snake Ji, she didn't dare to let Jing Ran encounter any danger, otherwise she wouldn't be able to explain when Zhang Jian came out.

Swish!

A golden light rushed out of the ruins, shining in all directions, attracting the eyes of Snake Ji and Jing Ran, and with a bang, a figure with golden rays flying out.

In an instant, the golden light shone on the heavens and the earth, and a strong and domineering aura roared out, making the snake queen frightened and buried her head even lower.

This figure is Zhang Jian, at this moment, Zhang Jian's breath is like a dragon, extremely strong, he has completely stepped into the sublimation realm, and has become a strong man in the sublimation realm. And his Supreme Divine Body has also reached the fourth layer!
