Fast forward some seconds and he's in the middle of a legendary forest spanning for thousandths of kilometers with lurking dangers in every corner. Divine beasts, legendary warriors and Hellish creatures fill the world. But Jake got an ability from this so-called System, which gives him the possibility to become the most hellish creature.
