"Ah... what the hell is this?" Tesser hadn't figured it out yet. He was just about to control Wu Tian's body when he was attacked.

The huge thunder energy came down with incredible fury.

Wu Tian was also not feeling well. He could still feel the sensation in his body. The eighth thunderbolt had such destructive power that his whole body was trembling.

Tesser was very angry. He had just taken control of Wu Tian's body and was preparing to attack his dantian with his fairy yuan. However, he was hit by a huge energy attack from behind. Although this level of energy was nothing to Teses, the amount of energy was huge. He had very little fairy yuan under his control and didn't know if he could defeat that energy.

Even if he did win, dealing with the true essence in Wu Tian's dantian would not be easy. Tesser was extremely frustrated. He couldn't even think about retreating now because he was controlling Wu Tian's body. The fairy yuan all around him was already fighting against the thunder energy, and there was no turning back for Teses. He gritted his teeth and fought against the thunder. He also had to keep an eye on Wu Tian's true essence in case he tried to launch a sneak attack.

In his spare time, Tesser looked outside. When he saw the huge robbery cloud in the sky, he was so scared that he broke out in a cold sweat. He couldn't understand what kind of robbery this was.

When he first entered Wu Tian's body, he had noticed that this guy definitely wasn't at the Yuan Ying stage. He should have been undergoing the Yuan Ying small heavenly tribulation in the cultivation world. Why was there such a huge robbery cloud? It was even more powerful than the big heavenly tribulation that the Yuan Ying stage cultivators undergo.

Although Tesser was shocked, he knew that his fairy yuan level was higher than the thunder energy level. He controlled his fairy yuan to block the thunder. The fairy yuan he controlled was much more powerful than the uncontrolled ones. He attacked in an orderly manner and also infused a small amount of thunder into Wu Tian's dantian to keep him occupied.

Wu Tian gritted his teeth and thought to himself, "Just you wait." He fought against Tesser with his true essence and the thunder Tesser intentionally sent over.

If Tesser knew that there was a heaven and earth spirit in Wu Tian's body, he probably wouldn't want to be in his body. It was as if he was looking for death.

The gray sky gradually turned black, just like the darkness of the night, pitch black and you couldn't see your fingers. The rolling black clouds occasionally flashed with lightning, proving that this was a very terrifying place.

The battle inside Wu Tian's body continued to rage on, intense and fierce. Wu Tian coldly watched them fight, occasionally battling some of the thunder Teses sent over.

At this moment, he looked at his dantian, and the human form formed by the pure energy had already grown to over a meter tall and was becoming clearer. He could vaguely see some of the features, and they were exactly the same as Wu Tian's.

Wu Tian's black hair reached his waist, and his bright eyes were like pearls. The wicked smile at the corners of his mouth was fully imprinted on his Yuan Ying. Although it hadn't turned real yet, as long as he crossed the ninth heavenly tribulation, his Yuan Ying would exist just like Wu Tian's.

The battle outside was about to end. Although his body occasionally split open, it was instantly healed.

Less than ten percent of the immortal essence quickly arrived at Wu Tian's dantian, where it saw his true essence, which was now less than half of what it had been originally. Tesser finally smiled, thinking to himself that he was clever to come up with a method to consume half of Wu Tian's true essence.

However, Tesser's next move was forgotten when he saw the unformed primordial infant next to Wu Tian's dantian. His heart was stunned.

"Tian...Earthly Spirit - Water? This... this thing can appear in the body of a cultivator?" Tesser's lips trembled as he spoke, and he was shocked.

Wu Tian coldly smiled at Tesser's stuttering speech. "Why can't this thing appear in the body of a cultivator? Don't make a fuss over nothing."

Tesser immediately woke up, realizing that no matter how this kid got this thing in his body, the key issue now was to leave.

However, Tesser was horrified to find that he couldn't move his body. A faint white light surrounded him, and no matter how he tried to mobilize the less than ten percent of his immortal essence, there was no response. Tesser's heart sank.

He was Tesser, the first fierce general under the seat of the demon god Buck in the demon realm. However, in the battle to seal the boundary, there were too many powerful beings, which led to the fall of even Buck, and Tesser himself could not escape. In the end, he was caught by the immortal world's immortal lord Guangyuan and turned into a sword spirit bestowed upon a disciple of the immortal sect.

I had originally thought that I could have a chance to be reborn in the future, but when I saw the world spirit in Wu Tian's body—the Water Spirit, he became hopeless. That was something that could completely annihilate him. Although he was just a member under the Great Demon King's throne, he couldn't possibly know about such a top-level thing. However, Tesseract heard of this ancient secret from Buck at a demon king gathering.

When Wu Tian saw Tesseract's silence, he thought of the Shadow Supreme. They were both pitiful people. Wu Tian only imprisoned Tesseract with Xiaoshui. Although Tesseract intentionally let in some heavenly thunder before, Wu Tian didn't blame him. He was also fighting for survival.

Although he was angry at the time, upon careful consideration, he might have done worse if he were in Tesseract's shoes.

"Tesseract, I don't care how powerful you were in the past. I'll give you two choices now: one is to return to your own fairy sword and be a hundred-year sword spirit, and I'll naturally let you out afterwards. The second choice is to be destroyed now."

Tesseract knew that what he said was true, and he had a way to destroy himself. After a moment of silence, Tesseract made an unchosen choice...

Carefully observing his body, he found that his meridians were already five times wider than those of other Yuan Ying stage cultivators, which was unparalleled. At least in the Tribulation Crossing stage, it might be similar to Wu Tian's current meridian width, and his skin was as rosy as a baby's.

Standing in the air above the sea, they were already very close to the tower. The edge of the calamity clouds seemed to be able to touch the tower, and looking at the dark calamity clouds, Wu Tian knew that his greatest challenge had come. Survive or die. Wu Tian no longer had any fairy tools now, and his current true essence could definitely not support him to resist the heavenly thunder.

Now, he could only rely on his Hundred Demon Sword. Everything was up to this calamity.

Wu Tian quickly flew towards the tower. It seemed that this final calamity was not so simple, rolling faster and lasting longer.

Wu Tian's palms were full of sweat, and he didn't have the confidence to pass this final calamity. The previous few times were already on the edge of life and death, and he had no reliance now. Thinking of the Black Dragon Fruit, Wu Tian shivered. He might still have to rely on it, but he didn't know if this last heavenly thunder could consume all the spiritual energy of the Black Dragon Fruit. If it didn't, there was no escape for him.

Wu Tian hesitated, and all the Golden Core stage demon beasts he encountered on the way were ignored. He flew high in the sky, and because his speed was too fast, the attacks of the Golden Core stage couldn't even touch his body now. After being washed by heavenly thunder and transformed by fairy essence, Wu Tian could be said to be a monster among monsters. He was too strong.

When he flew close to the tower, Wu Tian stopped and made a decision...
