I'll survive, gain levels, and become the strongest, right?!" Were his thought, as he still considered the situation to be a very realistic lucid dream, a drug trip, or a virtual reality experiment. It didn't take long for the reality in the form of overpowered monsters to destroy both his naivety and his body. Luke Walker died in agony, and it should be the end for him. But... Do you want to Load the last Checkpoint?  ...it was just the start of his suffering.
