Other people's systems: give away magical equipment, give away skills, and give away invincible plug-ins.
My system: send a countdown, send drawings, and send a sentence of "you can do it".
Someone else's mecha: fusion reactor, dark matter engine, particle cannon volley.
My mecha: Haier washing machine motor, Gree air conditioner compressor, Supor pressure cooker shield.
Others' ultimate goal: to dominate the universe and have a harem of wives and concubines.
My ultimate goal: to build a piece of junk that can punch out 8 minutes before the nuclear explosion.
Oh, by the way, I forgot to mention that.
This system was given to me now by the me before heat death.
And I am going to defeat the universe itself with this pile of junk.
