Saiyan Invasion

After the 23rd World Martial Arts Tournament, Sun Wukong held his wedding a month later, and everyone attended.

Just like that, half a year passed.

Krillin, Tien Shinhan, Yamcha, and Chiaotzu had already begun training inside the modified Spherical Spaceship using the gravity device.

However, given their current strength, 10x gravity was a struggle; they had to take it slow.

"Huh? Krillin, Yamcha, you're supposed to be training, why are you playing ping-pong?" One day, Sun Wumian decided to check on their progress.

"Huh? Isn't this for training?" Krillin asked, confused.

"Playing a sport like ping-pong under ten times gravity is actually very effective, and it's quite fun too," Yamcha added.

"Is that so?" Sun Wumian hadn't expected that; he had only asked Bulma to install it on a whim, as ping-pong was his favorite sport growing up.

"Yeah, it looks really effective. Their strength is improving rapidly. It's a pity I don't know how to play," Tien Shinhan said, stopping his training to walk over.

"Oh, well keep up the good work. I've brought plenty of Capsule food, enough to last you a long time," Sun Wumian said, handing them a box of food-filled Capsules.

Time flew by, and the growth rate of the Z Fighters exceeded Sun Wumian's expectations. A year later, even the weakest, Chiaotzu, had a power level exceeding 200. Gravity training was indeed remarkably effective.

As for Sun Wukong, since he had just gotten married, he couldn't leave home and could only spar with Sun Wumian in the mountains behind his new house during the day.

By the way, during this period, Sun Wukong's son, Son Gohan, was born. The reason he was also named Son Gohan was that after Chi-Chi gave birth, Sun Wukong was discussing names with the Ox-King and accidentally blurted out the name Son Gohan.

Little Son Gohan laughed non-stop when he heard it, but made a sour face at other names, so Sun Wukong, in his silly way, decided to name his son Son Gohan as well.

Well, that was very much in character for Sun Wukong—carefree and scatterbrained.

There was one more thing. After the new house, which was comparable to Bulma's, was built, Sun Wumian intended to have Grandpa Gohan come live with them. However, he was used to his life in the deep mountains and ultimately didn't come. Sun Wumian had no choice but to hire someone to renovate Grandpa Gohan's house so he could live more comfortably on his own.

Three years passed, and on a peaceful day.

Bang!

"Whoa! What was that?" A farmer was working hard when suddenly, something fell from the sky.

"What was that? A meteorite? I'll go take a look!"

Crash!

A Spherical Spaceship smashed a large, circular crater into the ground. Then, the hatch opened, and out stepped a Saiyan wearing unique armor, a power-level-measuring device over his left eye, and long, flowing black hair.

Unexpectedly, history had changed. Only three years had passed, and the Saiyan had already arrived.

Raditz stepped out of the Spherical Spaceship and jumped out of the crater.

"People are still alive on this planet. That brat Kakarot..."

"Who... who are you?" The farmer trembled, pointing his gun at Raditz.

"Beep... a piece of trash with a power level of only 5..."

"Don't come any closer, or I'll kill you! Ya-ya—"

Raditz caught the bullet with one hand and flicked his thumb, killing the farmer with his own bullet.

"Hmph, trash among trash."

Beep!

"Hmm? There's a powerful guy nearby, distance 4880... Is that Kakarot?" The detector sounded, and Raditz headed in that direction.

Soon, Piccolo sensed an astonishing power approaching.

"This power, is it Sun Wukong?" Piccolo looked up. "No!"

Thud. Raditz landed in front of Piccolo. "Hmph, not Kakarot."

"Who are you? Do you have business with me?" Piccolo asked.

"None!"

"Then why are you here? Looking to die?"

"What a cocky guy. Let me check your power level... Beep!" Raditz pressed his detector. "Oh, a power level of 322, but you're no match for me."

"What? Do you know who you're talking to?" Piccolo's face turned green with rage. This guy's power...

"I don't!"

"Hah!" Piccolo raised his hand, and a ki blast exploded right in front of Raditz!

"Cough, cough... amateur tricks, only good for kicking up dust."

He was completely unharmed? Piccolo's face turned an even deeper shade of green.

"My turn. Let me show you how it's done." Raditz raised his hand, preparing to attack.

Beep-beep-beep-beep...

Suddenly, the detector started ringing incessantly.

"What's going on? Why are there so many other powerful forces?"

Beep...

"Battle power 800, battle power 12000, battle power 1800, battle power 2500... What is going on? Is the scouter broken? The highest battle power reading has already surpassed mine?"

Whoosh! Raditz didn't even have time to deal with Piccolo; he quickly flew into the sky and retreated the way he came.

"Impossible. How could anyone on this planet have a battle power higher than me, an elite warrior? There is even one with a battle power of 1800?"

Whoosh... The spaceship restarted. Raditz had come quickly, and he fled even faster.

Obviously, with his own maximum battle power of 1500, he was no match at all, so he had to notify Vegeta first.

It was fortunate that he ran quickly, because shortly after, Krillin and the others arrived.

"A powerful force really was here on Earth just a moment ago, but it seems to have already fled," Krillin said, looking at the large crater on the ground.

"Could it be the Saiyan that Sun Wumian mentioned? I was just looking to test the results of my training; it's a good thing he ran fast," Yamcha said, clenching his fists and looking eager to fight.

"I don't know. Sun Wumian and Goku went to train with North Kai, so we'll have to wait until he returns to ask," Tien Shinhan said.

Later, Sun Wumian asked Bulma to build a dedicated Gravity Chamber at Goku's new home for training.

After years of training, Goku's strength improved rapidly, and his battle power soon reached 3000. However, after hearing about a technique called Kaioken, he insisted on going to King Kai's Planet to learn it.

Helpless, Sun Wumian thought about it and decided the timing was right, so he used Instant Transmission to take Goku to King Kai's Planet.

North Kai's small planet.

Goku and Sun Wumian had been there for several months.

It must be said that Goku's talent was even greater than Sun Wumian's; he learned Kaioken in just three months, whereas back in the day, it had taken Sun Wumian five months.

Currently, Goku was learning the Spirit Bomb, and he had already nearly mastered it. Perhaps because his battle power was higher, he was learning these techniques much faster than in the original timeline.
