Dragon Ball: My Silly Wife Is Devoted to Frieza

[Transmigration + One Saiyan Female Lead + Nearly Invincible + Cunning + An Easily Overlooked System] [The plot has been heavily altered] [The author is stubborn], so don't read if that bothers you. Ye Feng transmigrates into the Dragon Ball world and becomes the Saiyan Ke Lanfeng. After being gravely injured, he's abandoned on the ruined planet Yemuzu, and his spaceship is destroyed. Fortunately, his golden finger System comes online. It grants him infinite vitality, gets a five-star review, then goes off to idle. Having gotten lucky and found himself a Saiyan wife, shouldn't he do everything he can to stay alive? Step one: Recover from his injuries. Step two: Build a spaceship. Step three: Get stronger. Finally: Rule the universe! Wait, honey, stop trying to work for Frieza all the time. Honey, Planet Vegeta has been destroyed. You should take off your Scouter. Good girl! Your hubby's got something nice to show you!
