Jeff Norman cut down a mist monster. 
[Your physique has increased!]
[You gained a new ability: Blessing of Wind!]
[You gained Passive Ability: Aura Vision!]
Before knowing it, Jeff had already accumulated pages of abilities. 
Turned out, these abilities could stack on top of each other, without limit.
Detection range. Damage reduction. Maximum health. Regeneration speed. Movement speed. Reaction speed. Physical strength... 
Jeff: "Guys. I know I'm a bit invincible. But this is totally normal interaction. Please don't report."

Story Type: You've read about reincarnation, transmigration, world hopping... 
But have you ever read a story about parallel transmigration? Imagine transmigrating into multiple worlds... at the same time! 
I haven't seen any story of this type on this site. This might be a fresh experience for you.

Other names for this story: [Stacking My Abilities (Censored)], [Stacking My Passives Starting From Today], [My Isekai Clones],  [Me, Human, From Earth], [I Have Unlimited Passive Abilities!], [Regarding that time when I got transmigrated into many otherworlds at once], [Me and myselves in my Chat Space]

Stacking My Abilities

'Is there something you regret in life? Something that makes you wish: 'Only if I could start over again, and fix it.''

'I do. If I took a different path, maybe I wouldn't have lost Lord Rammus.'

'Pink ice cream was a bad idea after all...'

Holding a fishbowl in one hand, an umbrella in the other, Jeff walked down the street.

"Hey! Mister Mission Machine! Can I take a photo with you?"

'But without it, I wouldn't get this respect. I'll probably be that loser college graduate struggling to find a job. And end up working as a cashier... Can't pay my student debt.'

'So maybe things aren't all that bad for me.'

'Are there people you'd like to meet again in life? And make them go: 'Dang. You are doing so well now!''

'I... Maybe not. Especially not that cashier lady.'
