OP MC

SupernaturalOne day, my house got connected to a dungeon. It’s dangerous outside because of the monsters, but in order to survive, I have to clear the dungeon within the time limit! “I don’t want to die. I want to survive.” Kim HyunBok has to try and clear the dungeon by himself now that all the other explorers have died.

The MC accidentally entered a hidden boss lair when he was younger, and in the midst of corpses, he was found by the hidden boss and got adopted by him. The boss sees the MC as a toy at first, but as time goes by, looking at the interaction between the cruel boss and the young boy…they somehow seemed like a family

This is a world where evil creatures are gradually rampaging. However, the evil creatures are strong, they all disappear after this mental hospital, and even without dignity, they are reduced to ingredients and pets. This is the green mountain mental hospital, where talents are abundant and strong people are surrounded. In this regard, the seriously ill Lin Fan, who is carrying the system, said: I am definitely not a mental patient, I am a normal person who likes to cultivate.

He was suddenly summoned to another world one day. Monsters poured out, a huge disaster incoming. His ability the lowest. [Player's level is low] [Your level is hopeless] It doesn't matter whether you're the chosen or someone who travelled back in time. One must do everything they can, in order to survive. The Regressor's Instruction Manual. "It doesn't matter if I'm trash." Is there anyone who wouldn't do anything they could to survive?

You have entered the dungeon at Gwachun Station's 1st Exit.] Wait—? What is this?? A necromancer returns to Earth after 20 years and enters...the subway station? No, it's a dungeon. Bow down to the splendor of my one man army as I begin to seize it.

There once was the strongest Hero on earth.

"But he died though. How does a guy we killed gonna come back?"
"I know right. But if there was a way to come back, he would come back."

But did he really come back after 20 years?

"What are you so surprised about? Why. Did you do something to feel guilty about?"

You bastards. I won't let you get away with it.
