Take over This Different World

The system actually gave me a mission to save another world, but brother, if that's the case, can't you just say hello when someone travels through time? And this other world is really not peaceful. Human beings who are backward and about to lose their power, demons persecuted by cults, and powerful and terrifying monsters are really busy. What? Isn't that all? The undead race without bodies, the weapon spirit race whose souls can be transformed into magic weapons, the demons with the power of laws, the dragon race who can destroy the world with their bodies... Brother, do you want me to farm and make money, or do you want me to level up and fight monsters? ---------------------------------- I beg you all parents for your support, thank you~~~
