Infinite Survival: I Can Plunder Passive Skills无限求生：我有很多被动技

[Every Breath I take! i passively gain new skills while My Stats increase] or something like this type of system

I always (if I was ever Isekaied into different Universe) wanted a System that can mess around with the parameters of Reality itself like How U would a sandbox game. Basically the System gives ability to mess around with the local parameters of Reality, As I progress in strength so does the scope of capability of the system and also expanding its sphere of influence.

Also In a cultivation world, MC has a system that basically makes him the part time “Heavens” itself where He is basically the Heavenly Tribulations itself
So We can see both MC being ridiculously Powerful as heavenly Tribulations while also seeing a journey of Weak to Strong happen as a Normal mortal slowly ascending different cultivation levels

never seen this type but must have on mtl.

Systems eater.

Reincarnated as energy with a system.

There are numerous beings with systems. Other systems users can steal the systems of others to strengthen. Basically MC's system is top class and others are just imitation. They cant steal his but its also not shown whether he will or can steal other systems.

I read a story where people were brought into a new world and given a system just for them that only makes sense to them. One guy saw it as a game system where he could level it up. Another guy saw it as computer code and coded it different for different abilities. But they couldnt tell each other, because imagining a different system, conflicted with the current system.

Maybe a system that will grow along the lines of "My System is a Dev-Console" would be fine
