Reincarnated from ATLA With Kaio Shin's Evolved Fusion Skill

Dying from age, ugly old bastard Shaolan Li opened his eyes to a gender-switched martial arts Earth. Without any reincarnation cheat.
Beauties were everywhere around him.
Growing up in that setting where top models and other stunning babes were the dating scene's basic standard, he didn't know how to keep it in his pants.
He romantically spiraled, even if he knew that women were the more powerful gender now.
No more ugly bastard; he cumulated meaningless flings with the help of his serial lover boy's face.
In the end, Shaolan had many lady friends he couldn't dissuade from stalking his whereabouts.
Irony had him die at the hands of his strong wife with the evil queen's syndrome.
................................................................
Brutally whipped to death, Shaolan was reincarnated once more.
Ever so the optimist, he now had a system. A system that birthed other ones for him each day.
Deathless Soul. Capacity to combine stuff, which included more than just people.
Thanks to his main system, Shaolan found out whatever he didn't know about himself in his past lives and learned about his full potential.
He was excited. Everything was great. Better than before, except for one thing.
When he walked to keep at his scumbag pursuits with power this time, Shaolan felt his chest. The system also told him about the monumental, eruptive pistol in his pants that could tame things.
