A car accident took his parents' lives and left his younger sister with autism.
To earn money for her treatment, Lin Chen accidentally falls into the Void Realm, a place filled with slaughter and corruption.
Here, monsters read your memories, turn into the parents you love most or the sister you treasure most, then smile as they devour you.
At the brink of despair, Lin Chen signs a life-and-death pact with an eerie monster called "Zero Sequence."
Zero Sequence: It sees through the truth hidden beneath the rules and seeks the one and only path to survival, but every power comes at a price. Death has long been clinging to you like maggots to a bone.
Lin Chen: If you want to live with me, behave yourself. Stop saying all that creepy, cryptic stuff. Pull that again and we'll both die.
While others struggle desperately to survive in dungeons, fighting beneath the shadow of the rules,
Lin Chen relies on the eerie monster to move deftly along the very edges of those rules.
When faced with despairing mental corruption, Lin Chen draws the wooden sword at his waist,
turning his love for his family into a blade that can shatter despair.
When monsters wear his family's faces, Lin Chen grips a bloodstained sledgehammer.
"Use my sister's face to talk again, and I'll pound you into a pulp."
Zero Sequence: "You're so high and mighty. You make the threats, and I'm the one who gets beaten up."
