Reincarnated as a Saiyan with a System

Tarro and Bulma had a very enjoyable world touring trip, they saw all kinds of creatures, architectures, cuisines, sceneries and people.

...

One night in a secluded forest, when Tarro and Bulma finished their dinner in their capsule house.

"Bulma, we're all alone in the house." Tarro got close and whispered softly into Bulma's ears.

"Y-Yeah..." Bulma looked shyly at Tarro, her face flushed.

After some kissing and cuddling Tarro then pulled Bulma to the bedroom.

20 Minutes later.

"I guess it always hurts the first time, huh?" Tarro thought, he wasn't experienced at all, so this was a first for him. He hoped the next time would be better. He wasn't worried about Bulma getting pregnant, the system made sure he wouldn't impregnate her. Of course, that did not mean he was infertile.

Tarro carried Bulma to the bathroom to get her cleaned.

...

Over a year had passed, due to Bulma having school she had returned home. Bulma wanted to skip school, but Tarro told her it's better if she just worked extra hard and graduated earlier. Convinced, Bulma felt it was a good idea and went back. After another year of travel, where still would visit Bulma, he got bored.

'Hmm, I think I'll visit Kami and try and get him to take me to Other World so I can train under King Kai,' Tarro thought.

...

Tarro then teleported to Kami's Lookout.

"Tarro, it's been awhile." Kami greeted.

"Hey, Kami, how are you doing?" Tarro asked politely.

"I'm fine. All same as always. I remember you being just a child when you first came here. But now, you're already all grown up." Kami sighed.

"Yes, It's been quite a few years," Tarro reminisced the time he first came here, he was just 9 years old at that time.

"I've grown old, even older now, Tarro, you're the perfect successor I'm looking for," Kami looked deep into Tarro's eyes like he could see through everything of him.

"Kami, I don't have a pure heart, you should look for someone else," Tarro said with a wry smile.

Kami simply stared at Tarro without saying a word.

"I'm sure you'll find a good successor soon," Tarro said.

'The mortal world has tainted the pure heart you had as a child,' Kami thought to himself.

"So, Kami, I was wondering if you could take me to train under King Kai," Tarro asked.

"What, where did you learn of King Kai!?" Kami said surprised.

"Uh, he's very famous. He even taught the King Enma and I heard many demons praise King Enma for being King Kai's student." Tarro quickly decided to bullshit. Luckily he knew from the story that King Enma was King Kai's student.

"But, you're still a living person," Kami hesitated.

"But King Enma is also alive!" I argued.

"Alright, but I need to ask for King Enma's permission." Kami reluctantly agreed since it would be difficult for him to persuade King Enma to let a living person enter the Snake Way.

"Great!" Tarro said.

*Sigh* "Alright, give me your hand." Kami grabbed Tarro's hand and teleported them to King Enma's office.

"Eh, Earth's Guardian. What are you doing here?" King Enma asked the new arrivals.

"Hello Great King Enma, I would like to ask for permission for this young child to seek guidance under King Kai."

"You do realize you're asking for a live man to traverse the million-kilometre long Snake Way right? This young man will starve to death before he manages to finish it!" King Enma reproved Kami.

"Don't worry I brought a bunch of senzu beans with me!" Tarro said.

"No sins, good. Alright but don't come complaining to me if this guy dies" King Enma checked if Tarro had any sins before allowing him to go.

"Thank you King Enma!" Tarro said hurriedly before he changed his mind. Then a guide brought Tarro to the Snake Way.
