The Guardian

Korin glanced at Krillin, seemingly wanting to say something, but ultimately remained silent.

Krillin chuckled. "No need to say anything, Korin. I'm heading to the Lookout now." With that, Krillin leapt into the air and flew upward, leaving Korin Tower behind.

The Lookout wasn't too far from Korin Tower, and for someone like Krillin, it wasn't much of a challenge. As he ascended, the air grew thinner, and the clouds gradually faded.

Soon, he spotted the dome-shaped structure of the Lookout, ancient and radiating an aura of history that even surpassed Korin Tower. Krillin accelerated and landed softly atop the sacred platform.

Kami and Mr. Popo were already there, waiting for him.

Krillin approached, taking a moment to observe the two figures. Kami bore a strong resemblance to Piccolo, though there were differences. Kami wore a flowing cloak and robe, with the word "神" (God) emblazoned on his chest, and carried a staff. Piccolo, by contrast, wore the symbol for "魔" (Demon) on his chest.

Krillin smirked to himself, noting, Namekians sure do seem to love cloaks.

As for Mr. Popo, he resembled a small gorilla but carried a certain human-like charm in his demeanor.

"Kami, Mr. Popo, hello!" Krillin greeted politely.

Kami gazed at Krillin for a long moment before speaking. "Your fight with Piccolo was impressive. It's rare to see such a powerful martial artist emerge among humans. But why did you spare King Piccolo?"

"The new Piccolo may still be a bit evil, but he's not truly a demon anymore. In fact, I believe he could one day become a defender of Earth," Krillin replied with a grin. "Besides, if Earth were destroyed, how could Piccolo conquer it?"

"And if Piccolo died, Kami, you would cease to exist as well. The world still needs you."

Kami seemed melancholy, muttering, "I've noticed some reduction in Piccolo's evil intentions... but could he really become a protector of Earth?"

"I'm sure of it," Krillin thought. "From the moment he was born, the new Piccolo made defeating Goku his sole goal. He's stayed in the Wasteland of Yunzabit and hasn't committed any evil acts. Watching Goku's friendships and camaraderie will eventually influence him too."

Kami sighed and said, "I understand why you're here. You seek to refine your martial arts. Mr. Popo will guide you."

"Understood, Kami," Mr. Popo replied.

Krillin knew better than to underestimate Mr. Popo. The enigmatic attendant had been present since the time of the first Guardian of Earth. "Thank you, Mr. Popo," Krillin said earnestly.

"This way, please," Mr. Popo said, leading him to a spacious training area. Thus began Krillin's training at the Lookout.

The Training Begins

"The air on the Lookout is thin," Mr. Popo explained. "You'll need to adjust gradually. Also, your strength means you'll train wearing this tenfold weighted clothing."

He handed Krillin a set of weighted clothes, which Krillin donned. Immediately, he began to sweat.

"Keeping your energy constant is crucial," Mr. Popo said. "If you relax, the weight will crush you."

"You must learn to be as calm as the sky and as fast as lightning…"

One Month Later

Krillin was practicing punches and kicks, his energy steady and focused. He wiped the sweat from his brow and paused to check his system panel:

Power Level: 1450

Potential Remaining: 50

Energy Available: 52

Training Speed: Supersonic (35 days remaining)

Usable Energy: 2252

Krillin grinned. His control over energy had become almost perfect, and his power level was nearing its limit. "Almost there," he thought.

"You've improved quickly," Mr. Popo remarked. "You've already adapted to tenfold gravity."

Krillin chuckled nervously, thinking, Actually, I adjusted in seven days. I've just been banking time. If Goku can handle a hundredfold gravity in five days, I've still got a long way to go.

Realizing the benefits of gravity training, Krillin decided it was time to commission a gravity chamber from Dr. Brief.

Kami, though a Namekian who had lost his memory, still retained some training techniques, like mental sparring. This involved imagining a powerful opponent in your mind and battling them. It could even include psychic links for simulated fights with companions.

"Piccolo, also a Namekian, trained through meditation," Krillin thought. "Mental sparring not only boosts power but strengthens the mind. With a strong spirit, one gains sharper insights, learns faster, and might even develop supernatural abilities, like Guru reading memories or Goku's remarkable growth."

"I'll focus on mental sparring after I surpass my current limits," Krillin decided. "One step at a time."

Sitting cross-legged in meditation, Krillin resembled a monk, palms facing upward. Kami found the scene impressive, but Krillin smirked inwardly. Just putting on a show for effect.

Reaching the Limit

Suddenly, Krillin smiled. "It's time!"

Power Level: 1500 (Limit reached)

Potential Remaining: 0

Energy Available: 52

Training Speed: Supersonic (30 days remaining)

Usable Energy: 2252

The system chimed: "You've reached the human limit. Breaking through requires 100,000 energy."

"What? That's robbery!" Krillin exclaimed.

"Breaking limits isn't trivial. Energy conservation laws apply. Forgot you're not a science student?" the system quipped.

Grinding his teeth, Krillin reluctantly handed over 200 Senzu Beans. "Here. Start the process."

Breaking Through

"Find a quiet place for the breakthrough," the system advised.

Krillin flew to a desolate wilderness, far from Korin Tower. Even as he passed, Korin, indulging in a meal, barely noticed the blur overhead.

In the barren wasteland, devoid of life, Krillin nodded. "Let's begin."

The system initiated the process. The energies of the world converged on Krillin, enveloping him in radiant light. The transformation began, reshaping his body and soul.

Far away in the realm of the Gods of Destruction, Whis momentarily sensed an anomaly but couldn't pinpoint it. "Odd… Oh well, nap time while Lord Beerus sleeps!"

The Results

The light faded, and Krillin emerged, his body brimming with power. He laughed, "I feel unstoppable!"

Power Level: 2000

Next Limit: 150,000

Potential Remaining: 150,000

Training Speed: Supersonic (30 days remaining)

Usable Energy: 2252

"Two thousand!" Krillin exclaimed. "And the next limit is 150,000? Incredible!"

The system added, "Your dimensional tier is now Level 1, like Korin's. Kami is Level 3, Mr. Popo Level 2, and the divine hierarchy goes up to 10 with the likes of Zeno."

Krillin smirked. System, you're not so bad after all.

The system replied, "First use is free. Subsequent uses… heh heh…"

Krillin sighed, "And there it is."

He flew off, ready for the next challenge in his journey.
