Hello guys, I really need help to search for a novel I forgot about for a long time. Basically, what I remember is along those lines for the start : The MC goes on something like a hike and ends up in a cave. But then, the world changes and become something like a game world, where everyone are in tutorial zones except him who is trapped in the cave. He encounters monsters and is on the verge of death, so he puts all his stats into HP (vitality, endurance, stamina, can't remember exactly). And because he does that, he gains a skill that allows him to give dmg everywhere around him (except he takes those dmg those). Later on in the cave, he finds someone that wants to take over his body but he takes the OP armor. That's what I remember, i really hope you guys can help me for this.. Thx in advance !
