Mindlink System~Is it really a system??

What?? I died... wait i reincarnated... it's a wrong reincarnation?? and i died as a meat shield.. OMG I got another reincarnation. "i am gonna do something this time" I got a system but it's really not a system... maybe it's a alien tech. Cause a AI gave it to me in the world of fantasy. "huh? it went offline because I failed a task for the first time!!" is it really a system?? "Wait a minute... aliens are attacking because they wants my system?" "Huh? Magic? Elfs? Dwarfs? Gaints? Dragons and demons too? And humans don't know magic and don't have physical power...? How am I suppose to fight? " "Wait a minute...i am mc, i should use my OP earth's knowledge to fight them...yes let me show them the power of science...the power of humans..." "but...my system? It it a creature? Or a ai? Then where is computer? So many questions..." "What is going on?? do you want to know? then why are you reading this?? just read and determine if it really a system or not"
