Left Hand Raising Planetary Devastation, Right Hand Swinging Golden Wheel Reincarnation Explosion

Time passed slowly.

Uzumaki Shusen devoted himself entirely to the experiment, oblivious to everything outside.

The two Shadow Clones beside him had already fused three or four pairs of eyes, yet he was still steadily advancing through the fusion process.

After all, this was his first time conducting such an experiment. He did not dare to rush for results. Sharingan and Byakugan were hard to come by, their value impossible to measure in money. Any losses that could be avoided had to be avoided.

Who knew how long passed before the night faded away and a ray of dawn shone upon the land.

"Success!"

Inside the laboratory, Uzumaki Shusen cried out, unable to hide the excitement on his face.

After working through the night, he had successfully integrated the Byakugan's ocular power into the Sharingan. This was a milestone breakthrough in his study of eyes!

Inside the solution, the fused eye was entwined with red, white, and black, looking extraordinarily bizarre, like the cursed eye of a demon.

"I wonder what ocular technique this eye possesses... hypnosis? X-ray vision? Izanagi?"

Uzumaki Shusen picked up the eye and used Kagura's Mind's Eye to sense the ocular power radiating from it, intending to transplant it into himself and give it a try.

But just then—

"Not good!"

Uzumaki Shusen suddenly sensed the ocular power within the eye becoming violent and chaotic. A fierce fluctuation spread out, and it was about to explode.

"To hell with you!"

With a backhand motion, Uzumaki Shusen struck the eye with two Four Symbols Seals, instantly stacking them into an Eight Trigrams Seal and suppressing the rampaging ocular power.

Still uneasy, he cast another four sealing techniques in succession, only stopping once the ocular power had completely calmed down.

"So this path won't work?"

Uzumaki Shusen felt deeply regretful. He had thought he had created an entirely new kind of eye, only for it to be a fleeting joy.

The repulsive force between the Byakugan's ocular power and the Sharingan's ocular power was too great. Even if they were temporarily fused together, they could not remain stable for long and would inevitably rupture and explode.

Uzumaki Shusen could sense that if the ocular power contained in this eye exploded, its force would be roughly equivalent to two explosive tags.

"Is there some medium with a gentle attribute that can balance the ocular powers of the two eyes and stop them from repelling each other?"

Uzumaki Shusen pondered. A moment later, an idea truly came to him in a flash of inspiration.

"If we're talking about gentle attributes, Wood Release is definitely the best. I can get some of Hashirama's cells and try them."

Because of his Sage Body, Hashirama's cells had been an all-purpose solution in the original story. They had not only allowed Madara to awaken the Rinnegan, but also cultivated an army of White Zetsu. If Hashirama's cells were used as a medium, perhaps they really could perfectly fuse the Byakugan and Sharingan.

"What a headache. Hashirama's such an overpowered freak—how am I supposed to get his cells..."

Uzumaki Shusen found himself in a difficult position. Obtaining Hashirama's cells seemed even harder than gouging out Sharingan.

Perhaps he could only slowly look for an opportunity on the battlefield in the future and secretly collect some of Hashirama's tissue.

After remaining in the laboratory for a while longer, Uzumaki Shusen glanced at the clock on the wall and figured it was about time to return to the clan grounds.

His father was holding an elders' meeting today. If he was late, there definitely would not be a pleasant outcome.

He left behind two Shadow Clones to continue fusing Sharingan and Byakugan while he himself used Earth Release to leave.

This experimental base had been built a thousand meters underground. Other than several vents, there were no direct passages leading to it. One had to use Earth Release to reach it. It was exceptionally secure and concealed; unless Uzumaki Shusen exposed it himself, ordinary people had virtually no chance of finding it.

While traveling through the earth, Uzumaki Shusen kept his Byakugan activated the entire time to scout the situation aboveground and avoid being noticed.

In the courtyard of an estate, the ground suddenly rippled like water, and Uzumaki Shusen poked his head out.

He had already used his Byakugan to confirm the situation, so he climbed out of the earth openly and used sealing techniques to seal the ocular power in both his eyes.

The Uzumaki Clan was famed throughout the ninja world for its sealing techniques. Influenced by this, Uzumaki Shusen had mastered every sealing technique within the clan. Once the ocular power of the Sharingan and Byakugan was sealed, they immediately became like lamps without power, reverting to ordinary eyes.

Uzumaki Shusen had to seal their ocular power. The matter of him transplanting Sharingan and Byakugan absolutely could not become known to outsiders. Otherwise, not only would he suffer the heavy retaliation of the two great clans, but he would also drag down the Uzumaki Clan.

"There's still some time before the elders' meeting. I'll take a bath first."

Uzumaki Shusen headed toward the bathing room in the estate. He had spent last night among the battlefields of the Uchiha and Hyuga, and a faint smell of blood still clung to him.

However, he was not worried that anyone would see anything unusual about him, because there was no one else at home right now.

There were three members in his household. His father, Ryū, was the Uzumaki Clan's patriarch and a workaholic. Every day, he stayed busy in the patriarch's building handling the clan's affairs, discussing with the elders which ninja clan to attack tomorrow and which ninja clan would attack them the day after. He was rarely home year-round.

His older sister, Mito, was eighteen this year and publicly recognized as an elite jonin within the clan. She had awakened the Adamantine Sealing Chains bloodline limit and was as famous as geniuses like Hashirama Senju, Uchiha Madara, Hyuga Tenjin, Sarutobi Sasuke, Kurama Yaichi, and Kaguya Wuzhan. She possessed both beauty and strength, enjoying great renown among the major ninja clans.

Ever since the Uzumaki Clan had ceased hostilities with the Kaguya Clan half a month ago, Mito had been helping the wounded in the hospital. Uzumaki Shusen had not seen her for several days.

The last member of the family was his younger brother, Ashina, who was thirteen this year. He had passed the Uzumaki Clan's jonin examination last year and was also a formidable genius.

Two days ago, at Uzumaki Shusen's instruction, Ashina had presented Ryū with a grand plan for the clan's development. His father had then shut him in the patriarch's building, and he had not returned since.

"My sister and brother are both geniuses. The pressure on me is really huge..."

Uzumaki Shusen gave a wry smile and took off his clothes, revealing his fair, muscular body, a firm, powerful waist, and clearly defined eight-pack abs.

Then came the sound of rushing water as he began bathing.

Uzumaki Shusen had never been as dazzling as his sister and brother. Over the years, he had kept a low profile in front of others. In the eyes of his clansmen, he was merely a sixteen-year-old special jonin—neither a genius nor trash, just an ordinary person.

It was necessary for him to hide his abilities. He had done so many infamous things on the battlefield under the name Black Zetsu that his true identity could not stand out too much. Otherwise, he might expose a flaw. The less attention he drew, the better.

Perhaps one day, once he fused the Sharingan in his laboratory into Rinnegan and the Byakugan into Tenseigan, with the Rinnegan in his left eye and the Tenseigan in his right, raising Planetary Devastation in his left hand and swinging Golden Wheel Reincarnation Explosion with his right...

By then, even if he revealed his identity, there would be nothing to fear.
