Dragon Ball Human

Of course Yamiru wouldn't personally train the white cat in martial arts indefinitely. He still needed his sleep...ahem, his dedicated cultivation time. 

It wasn't until the third year, when the white cat finally managed to graze the hem of Yamiru's divine robe, that he summoned Mr. Popo from the Lookout to serve as the cat's training partner. 

Though Mr. Popo said nothing, Yamiru could sense his reluctance. After all, the white cat hadn't ascended to the Lookout, nor was it Yamiru's chosen successor as the next deity. 

But Yamiru made an offer: "If you can properly train it, we can have it permanently reside at Korin Tower as an auxiliary immortal—or perhaps call it a 'temporary deity'? Essentially, it would become the Lookout's gatekeeper." 

Only then did Mr. Popo cheerfully accept, taking the bells Yamiru handed him and fastening them at his waist before beginning earnest training with the white cat. 

Of course he took it seriously—this cat would become the public face of the Lookout. If some random martial arts master climbed Korin Tower only to find the gatekeeper couldn't maintain order, that would reflect poorly indeed. 

"At its current progress rate, I wonder if a hundred years will be enough for it to graduate from Mr. Popo's training?" Yamiru mused as he departed. The cat's lifespan was another concern—he couldn't fathom how the future Korin lived so long. Did Mr. Popo give it special treatment? 

Even as the first-generation God of Earth, Yamiru lacked the authority to arbitrarily extend a mortal's lifespan. To him, the difference between life and death was merely the presence or absence of a halo (a heavenly residence permit). 

Thus, he never considered using the Dragon Balls to prolong the lives of loved ones like Tights. Wouldn't it be better to reunite in the afterlife after experiencing life's natural cycle—forever young? In this way, Yamiru came to understand Goku's perspective in the original story. When Goku told his family "We'll meet again in the afterlife," he meant it quite literally. 

Riding the winds, Yamiru returned to the Lookout. Atop the slender Power Pole, the hemispherical structure floated majestically, its grand palace now nearly complete after centuries of construction. 

After nearly forty thousand years, even slackers like Yamiru and Annin couldn't delay completion forever. This meant Yamiru's duty as the first Kami of Earth, and Annin's role as acting Kami, were drawing to a close. 

Annin would have no more excuses to linger in the mortal world—she would return to Mount Five Elements to tend the furnace. Truth be told, after forty millennia, she'd seen all the beauty the human realm had to offer. Lounging at the mountain, eating hot pot and sleeping the days away didn't sound bad at all. As a goddess, while she couldn't freely roam the human world, vacationing in the afterlife remained an option—hence why she'd later recruit the deceased Gohan as her bodyguard. 

As for Yamiru... 

In King Yemma's words: "Do as you please." Since Earth's Kami was so capable and enjoyed traveling, let him. From Yemma's perspective spanning billions of years, whether Yamiru lingered in the mortal world for tens or hundreds of millennia mattered little—eventually he'd return to the afterlife, perhaps even reincarnate. For all his merits, Yamiru's experience and vision remained limited by cosmic standards. 

This counted as a significant achievement over forty thousand years, Yamiru mused with a quiet laugh—earning Yemma's tacit approval. Of course, this tolerance stemmed from Yamiru remaining on Earth and avoiding mischief, not to mention his connections with King Kai and perhaps even the angels (whether Yemma knew about those or not). Such privileges between life and death didn't come easily. 

Annin and Joey weren't at the temple. Without bothering to sense their ki, Yamiru entered alone, seeking a quiet corner for meditation. As he walked, something caught his attention. 

"Isn't this the Hyperbolic Time Chamber?" He stopped before the familiar door. 

It must have been Annin's work—Yamiru had personally experienced the spacetime properties of the Furnace of Eight Divisions. But recreating them? That seemed overly ambitious. Perhaps Joey had assisted. 

After brief observation, Yamiru pushed the door open and stepped inside—immediately assaulted by air even thinner than the Lookout's high-altitude environment. 

Nearly 50-degree Celsius heat. A disorienting, endless white void... 

No wonder Goku couldn't endure this place! Even when training his son to achieve Super Saiyan, they'd left early. Yamiru shook his head—this hellish environment completely contradicted the Turtle School's philosophy and Earth's martial arts fundamentals. How could anyone properly rest or achieve mind-body harmony here? 

This place was only suitable for intensive crash courses, not sustained cultivation. Yamiru reached his conclusion. 

Just as he was about to leave, Yamiru paused mid-air above the endless white expanse. Taking a light breath to adjust his state, he noted: "The natural energy here is pitifully scarce—the body can barely draw any power from the environment..."

As this thought crossed his mind, strands of luminous energy began swirling through his hair, while his eyebrows took on a silvery-white glow. His eyes snapped open.

"Ka...me...ha...me...ha..."

Mouthing the four syllables soundlessly, Yamiru thrust his palms forward, unleashing a torrent of near-divine energy into the void. His Golden Veil tracked the distortions in the air as spatial cracks briefly appeared—but failed to rupture completely.

"Still not strong enough," Yamiru murmured, closing his eyes to suppress the divine cells that now comprised 95% of his being. With a long exhale, he assessed: "Destructive power still falls slightly short of Gotenks' Super Saiyan 3 or Majin Buu's full strength."

Four millennia had passed since the first divine cell manifested in his body. Now only 3% of his brain cells and 2% of his ocular cells remained mortal. The faint glow in his golden eyes pulsed rhythmically—this final transformation couldn't be rushed. He still had eight centuries... and even if he couldn't fully convert the remaining cells by the original timeline's events, it hardly mattered. Enemies like Freeza or the androids would pose no threat to his current power. Even an unexpected resurrection of Majin Buu wouldn't guarantee victory against him now, let alone against his future self eight hundred years hence.

"Only when the remaining 5% fully transform will I truly step into the divine realm," Yamiru mused. Not as a temporary god like the Super Saiyan God, but as a true deity perpetually in that state—his path mirrored the Original Saiyan God's, while any descendants might follow the Super Saiyan God's ritualistic approach. 

Not that one method surpassed the other—both were merely tickets to Ultra Instinct. Though Yamiru's natural divinity could be considered the "official admission," while the ritual-based transformation was more like... scalped tickets.

"Ultra Instinct..."

As the Dragon God had explained, true Ultra Instinct represented a conceptual ultimate truth—something that could never be fully grasped, only endlessly approximated. 

Yamiru suspected this so-called "true Ultra Instinct" might be what the legends called All God. 

Every being's path to divinity was ultimately the pursuit of Ultra Instinct—which meant... inherit the mantle of All God?

"Time to resume cultivation."

Yamiru's meditation this time lasted nearly two centuries. When his eyes finally opened, they met Joey's innocent face hovering before him. Scooping her up, he gave the squirming girl a playful rub before depositing her on his shoulder despite her muffled protests. 

As he exhaled slowly, pure heavenly energy flowed from the halo above his head, instantly absorbed and refined by the 97% divine cells throughout his body. Only 1% of his brain and 2% of his ocular cells remained unconverted.

While Joey amused herself by tugging his hair, Yamiru hadn't awakened without reason. Rising to his feet, he gazed thoughtfully toward Earth's horizon where a white insectoid object was piercing through the atmosphere.
