Seeing his stats, he decided to leave it be for now. "Well, this is the overall of my skills. I've integrated several fighting skills from my homeworld, though. Fuse it with HoYuu (Hollow Yuuki)'s unpredictable and Old man Zangetsu Quincy's fighting skills."

Instead of calling his Hollowed Zanpakuto his original name, he decided to call him Hoyuu or Hollow Yuuki in short form. Quincy Zangetsu is just an 'old man' since he is Yhwach's manifestation in his world. Since he isn't tied to Yhwach in this world, he agrees to be his master in Quincy's prowess. With the System's help, Zangetsu can now harmonize its power alongside his Quincy ability without overlapping each other. This way, both can become as strong as he wants.

Yuuki emerged in his inner world. He wore a black shihakusho and a red strap from his right shoulder to his waist. Accompany by his handsome and long black hair; he was like a god among men. Adding the first stage Zangetsu on his back shows he is in his realm.

"Well, technically, I am a shinigami." He slowly thinks as if he is overpowered in the next world, but Shinigami is still in a mode. He continued, "Since it was kind of overpowered, I'll use it if I need to show off and maybe find a way to merge his human and shinigami."

Adding a little smirk, he thought about his unmastered hollow mode. He made a deal with HoYuu that he could only possess him if Yuuki needed him in quests. Additionally, Hoyuu could have his body if he went unconscious because he needed last-minute protection.

HoYuu recognized Yuuki as his king when Yuuki beat him several times in their training. He adapted his fighting style, constantly making him unpredictable and using some of his Quincy's abilities. Thus, it enables him to switch between close fights and long-range fights. Even if he won, he remembered HoYuu was strong if he used the Full Resurrection Mode, just like Hollow Ichigo from the anime. He's not ready to face such a powerful yet.

He doesn't have a body cultivation art at all. So, it hurts like hell when being whacked by the Old Man and Hoyuu. The latter had more fun beating the living shit out of him.

He discovered that his combat and body capabilities could skip two tens of levels above him. If his body and combat capabilities are on level 10, he can easily fight someone at level 30. On level 50, he can fight anyone on level 70. It means he can suppress anyone within levels 0 and 70 with his absolute suppression.

Absolute suppression is a skill from the System that utilized his reaitsu to suppress anyone to the point that they can't get up. It was a skill mainly used for stun and intimidation.

The thing is, how the hell he gained experience points up to level 50? In his inner world, old man Zangetsu can conjure up clones of himself at different levels. Thsuccessiveus defeat of the clones skyrockets his levels. He gained 50 levels for combat and body for an unknown period. Every time he leveled up, the System would award him 10000 SP, but Yuuki was the type to use skills one at a time to develop his fighting combos and patterns. He continuously learns to fuse skills and create skill combos before purchasing a new one.

Looking at the empty void, he promised to decorate his inner world using his style. Last time, he was in Zangetsu's Inner world, not his own. He had planned to develop it instead of remaining it as an empty realm.

But right now…

"Yo king, maybe it is time we find a suitable world to wreak havoc!" Hoyuu sounded by his side.

"It's been a while since I went to the world of the living." Old man Zangetsu continued.

He nodded his head in enthusiasm. "I am working on it. System… I am ready. Initiate Host Fusion to the Human World."

[Searching suitable host.]

[Suitable Host acquired.]

Then, he was covered in bright lights before being sent away from the void.
