Spirit Bomb and Ultra Instinct Are Similar?

"Yes!" Krillin and the others hurriedly replied.

"Can we take off these heavy clothes now?" Yajirobe asked.

Why did you have to include me?

I don't want to fight at all.

In a certain mountain range.

Son Gohan sat on the ground, bruised and battered, grimacing in pain.

"Hmph, you've finally managed to kick that habit of crying over the last six months." Piccolo sat right beside Son Gohan.

"Hehehe..." Son Gohan chuckled foolishly and asked, "Uncle Piccolo, have you ever fought my dad before?"

"Our battle isn't over yet. Once we defeat the Saiyans, it'll be your father's turn." Piccolo snorted.

"But Dad once said that since you were reborn, Uncle Piccolo isn't as vicious as you used to be." Son Gohan giggled.

"Hmph!" Piccolo bared his teeth.

Brat, why do you have to speak such blunt truths?

"I think so too, even though Mom and Grandpa are both terrified of you." Son Gohan said with a smile.

Piccolo: "..."

"Enough nonsense, get to sleep! Tomorrow's training won't be this easy!" Piccolo scolded.

"Yes! Yes!" Son Gohan hurriedly replied.

Immediately after, Son Gohan flopped over and fell asleep.

"What a little idiot!" Piccolo gritted his teeth.

Just like that, another 40 days passed.

Son Goku had already adapted to the 10x gravity on King Kai's Planet.

"Snap!"

Son Goku accelerated, reaching out and grabbing Bubbles the chimpanzee.

"Finally caught you! That's great!" Son Goku hugged the chimpanzee in excitement.

"Well done!" King Kai couldn't help but praise Son Goku's outstanding performance.

He really is a talented guy; he adapted to this planet's gravity so quickly.

I have to say, even though this kid lacks manners, his heart is truly kind.

"Are you ready? My training is even more grueling than you can imagine!" King Kai asked loudly. "Can you endure it?"

"Yeah, I can!" Son Goku nodded, his expression filled with excitement.

After these 40 days of cultivation, Son Goku suddenly felt that his strength had improved by more than just a little bit.

Damn, this seems to be much more effective than that Ultra Instinct of Luo Tian's.

I'm a bit conflicted now.

Should I keep training here, or continue learning Luo Tian's Ultra Instinct?

But I know clearly that Luo Tian's Ultra Instinct should have more potential.

However, if I can't beat those two Saiyans coming to Earth, there's no point in training Ultra Instinct.

I'd better train in King Kai's techniques first.

Once I take care of those two Saiyans, I'll continue training in Ultra Instinct with Luo Tian.

"You must become the best in the universe, both physically and mentally. Can you do it?" King Kai asked.

"Understood!" Son Goku clenched his fists, his face full of confidence.

"Before that, I'm going to go have a cup of tea." King Kai said.

Son Goku collapsed to the ground.

After finishing his tea, King Kai began a sparring session with Son Goku.

"Bang!"

Hearing a dull thud, King Kai slapped Son Goku, sending him flying backward until he crashed into the ground.

"So strong!" Son Goku was astonished.

"Alright, continue." King Kai beckoned.

"Bang, bang, bang!"

The two of them engaged in a fierce confrontation on King Kai's Planet.

"Kaioken!"

King Kai immediately unleashed the Kaioken, giving Son Goku a sound thrashing right then and there.

Son Goku was left black and blue, grimacing in pain.

"That's right, just as you saw, this is the Kaioken. It can drastically increase one's own strength," King Kai said with a smile.

"That's amazing! No wonder Luo Tian told me to come train with you," Son Goku laughed.

"Who is Luo Tian?" King Kai asked.

"You wouldn't know him. It's a hassle to explain, so let's just leave it at that," Son Goku said, scratching his head.

"You brat! Leaving things half-said!" King Kai barked, annoyed.

The training continued.

The day for Vegeta and Nappa to descend upon Earth was drawing ever closer.

Krillin and the others on Earth had also begun their own hellish training.

On King Kai's Planet.

Son Goku had already mastered the Kaioken.

King Kai, not holding back, also taught Son Goku how to use the Spirit Bomb.

"Bang!"

Just a moment ago, the Spirit Bomb controlled by Son Goku had struck a high-speed moving rock out of the sky.

"Not bad, well done, Son Goku. I didn't expect you to be so proficient with the Spirit Bomb already," King Kai said, deeply surprised.

"Hehe, it's the result of hard training," Son Goku grinned.

"As I said before, the Spirit Bomb is a technique that gathers the energy from all living things—grass, trees, humans, animals—and the atmosphere of the world, then releases it," King Kai explained. "On such a small planet, the Spirit Bomb already has this much destructive power. The Earth you fight on is many times larger than this place, and it has the sun providing massive energy as a backup. You will possess a Spirit Bomb with unimaginable energy; if you're not careful, you might even destroy the very planet you're supposed to protect. Therefore, try not to use the Spirit Bomb... only use it as a last resort."

"Understood. I can defeat them using the Kaioken," Son Goku said with a smile. "But come to think of it, this Spirit Bomb... it's actually a bit like the Ultra Instinct I've been learning... there's a slight similarity."

"Here we go again! Don't mention that Ultra Instinct in front of me!" King Kai snapped. "Last time you trained in Ultra Instinct, your strength clearly declined."

"That... Ultra Instinct, it just makes you feel like my strength has declined," Son Goku laughed. "But in reality, my strength has actually increased."

"What kind of nonsense is that?" King Kai rolled his eyes and changed the subject. "Enough of that. The day of the decisive battle is getting closer... the Saiyans will arrive on Earth tomorrow. Right, you should hurry back to Earth and prepare."

"Go back now?" Son Goku was slightly stunned.

"Otherwise what? Do you want to stay here until the New Year?" King Kai glared.

"Alright, I suppose it's time to return to Earth," Son Goku nodded. "I still need to go back and get used to Earth's gravity again."

"Good," King Kai nodded.

Then, the two of them stared blankly at each other.

"King Kai... aren't you going to let me go back to Earth? Hurry up and send me back," Son Goku said.

King Kai: "..."

What the hell!

You want me to send you back?

"Go back the same way you came! I have no way of sending you back!" King Kai shouted.

"This is a headache... I don't know the way," Son Goku scratched his head, looking completely helpless.

"Didn't you say someone brought you here? Just have that person come back and pick you up," King Kai replied.
