The Saiyans Arrive

After the 23rd World Martial Arts Tournament, Goku and Chi-Chi's wedding was held 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 spaceship, making use of its gravity device.

However, with their current strength, even ten times gravity was a struggle, so they had to take it slowly.

"Huh? Krillin, Yamcha, you're supposed to be training. Why are you playing table tennis?" Sun Wumian came by that day to see how their training was going.

"Huh? Isn't this how we're supposed to train?" Krillin asked in confusion.

"Playing table tennis under ten times gravity is great training, and it's fun, too," Yamcha said.

"Really?" Sun Wumian hadn't expected it to work that way. He'd only asked Bulma to install the table on a whim, since table tennis had been his favorite sport since childhood.

"Yeah, it seems to work really well. Their strength is increasing rapidly. Too bad I don't know how to play." Tien Shinhan stopped training and walked over.

"Oh, then keep it up! As for food, I've brought you plenty of Capsules again. You'll have enough to eat for a long time." Sun Wumian handed them a box of food Capsules.

Time flew by, and the Z Fighters grew faster than Sun Wumian had expected. A year later, even the weakest of them, Chiaotzu, had a power level over 200. Gravity training really was effective.

As for Goku, since he'd just gotten married and couldn't leave home, Sun Wumian sparred with him in the mountains behind his new house during the day.

By the way, during this time, Goku's son, Gohan, was born. Why was he also called Gohan? After Chi-Chi gave birth, Goku was discussing the baby's name with the Ox-King when he accidentally blurted out the name Grandpa Gohan.

When Kid Gohan heard it, he kept laughing, but whenever they suggested another name, he made a sour face. So Goku, being the simpleton he was, named his son Son Gohan, too.

Well, it suited Goku's easygoing personality.

There was one other thing. After the new house was finished—almost as big as Bulma's—Sun Wumian had planned to invite Grandpa Gohan to live with them. But the old man was used to life in the deep mountains, so in the end, he didn't come. Sun Wumian had his house renovated instead, making it more comfortable for him to live alone.

Three years passed. Then, one peaceful day—

Bang!

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

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

Crack!

A Spherical Spaceship smashed into the ground, leaving a huge circular crater. Then the hatch opened, and a Saiyan stepped out. He wore distinctive armor, had a device over his left eye that measured power levels, and sported long, flowing black hair.

History had changed. It had only been three years, and the Saiyans had already arrived.

Raditz climbed out of the spaceship and leaped from the crater.

"The people on this planet really are still alive. That brat Kakarot..."

"Y-you! Who are you?" The farmer shakily pointed his gun at Raditz.

"Beep... A worthless weakling with a power level of only five..."

"Don't come any closer, or I'll kill you! Yaaah—"

Raditz caught the bullet with one hand. With a flick of his thumb, he sent it flying back and killed the farmer.

"Hmph. A piece of trash among trash."

Beep!

"Hm? There's someone with a high power level, 4,880 away... Is that Kakarot?" The Scouter beeped, and Raditz headed in that direction.

Before long, Piccolo sensed an incredible power approaching.

"This power... Is it Son Goku?" Piccolo looked up. "No!"

Tap. Raditz landed in front of Piccolo. "Hmph. You're not Kakarot."

"Who are you? What do you want with me?" Piccolo asked.

"Nothing!"

"Then what did you come here for? To die?"

"What a mouthy little guy. Let's see your power level... Beep!" Raditz pressed a button on the Scouter. "Oh, your power level is 322. Still no match for me."

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

"No idea!"

"Ha!" Piccolo raised a hand, and a blast of ki exploded in front of Raditz!

"Cough, cough... Pathetic technique. All it did was kick up some dust."

He wasn't hurt at all? Piccolo's face turned even greener.

"My turn. I'll show you how it's done." Raditz raised a hand, ready to attack.

Beep, beep, beep, beep...

Suddenly, the Scouter started beeping nonstop.

"What's going on? There are so many powerful energy signatures?"

Beep...

"Power level 800, power level 12,000, power level 1,800, power level 2,500... What's going on? Is the Scouter broken? The strongest one is already stronger than me?"

Whoosh! Raditz didn't even have time to deal with Piccolo. He shot into the sky and flew back the way he'd come.

"Impossible! How could anyone on this planet have a power level higher than me, an Elite Warrior? And one of them even has a power level of 1,800?"

Whoosh... The spaceship started up again. Raditz had arrived quickly, and he left just as fast.

Of course. His own power level only reached 1,500, so he wasn't a match for them. He had to warn Vegeta first.

Fortunately, he got away quickly, because Krillin and the others arrived not long afterward.

"There really was a powerful presence on Earth just now. It seems to have run off," Krillin said, looking at the crater.

"Could it have been the Saiyan Wumian told us about? I was hoping to test how much our training had paid off. Lucky for him he ran," Yamcha said, clenching his fists, eager to fight.

"I don't know. Wumian and Goku went to train with King Kai. We'll have to ask when they get back," Tien Shinhan said.

Later, Sun Wumian asked Bulma to build a Gravity Chamber at Goku's new house for him to train in.

After years of training, Goku's strength had increased rapidly, and his power level soon reached 3,000. But when he heard about the Kaioken, he insisted on going to King Kai's Planet to learn it.

Sun Wumian had no choice. After thinking it over, he decided the time was about right, so he used Instant Transmission to take Goku to King Kai's Planet.

North Kai's little planet.

Goku and Wumian had been here for several months.

It had to be said that Goku's talent was every bit as good as Wumian's, if not better. He learned the Kaioken in only three months. Back then, Sun Wumian had taken five.

Goku was currently learning the Spirit Bomb, and he was nearly done. Maybe because his power level was higher, he was learning all these techniques much faster than in the original story.
