Dragon Ball: Father of the Legendary Super Saiyan

(The opening focuses on having children. I originally wanted to write a Baby arc as a transition, to carry the protagonist through his youth, but readers said the arc wasn't very good. If you don't like it, feel free to skip the Baby arc. Things gradually return to the usual rat race from Volume 8 onward. The story will continue to center on the rat race, with the protagonist like a walking Sunflower Manual. If you have a Legendary Super Saiyan child with the protagonist, you can't win the rat race. But if you don't have a Legendary Super Saiyan child, you definitely lose. Dear readers, skip the Baby arc and take another look further ahead. The drop in my stats has me a little worried.) A bachelor transmigrates as Paragus, and with his lecherous nature boosted, the Legendary Super Saiyan is born a whole era early. Everything goes haywire. As the saying goes, in times of crisis, the women go first. The Saiyans of this generation have a severe gender imbalance, and the widows are piling up. When they realize they won't reach ten thousand in their lifetime, but their son is born with a power level of ten thousand, they can't help rushing to have children. Vegeta II: They're all Legendary Super Saiyans, so dangerous! What? The royal family can have one too? What danger? He's a pillar of the future. Vegeta III: Where's my throne? Did someone steal it from me? Vegeta IV: I'm supposed to be the second male lead. Why can't I be born? The Tuffles: What's the point of fighting? Let's coexist. This place is just another Earth. Frieza: What do you mean, the first Saiyan I meet is an adult Broly? Beerus: I took one nap and the sky fell. What do you mean there are hundreds of Legendary Super Saiyans competing in the rat race?
