Ye Xuan always thought his aloof roommate was impossible to understand. Cold, distant, and expressionless, the man kept everyone at arm’s length, speaking little and revealing even less. But when the zombie apocalypse erupts without warning, Ye Xuan discovers that beneath that icy exterior lies someone willing to risk everything for him. The first thing his roommate does is fasten a bite guard over Ye Xuan’s mouth, then fight through endless hordes of zombies to bring him to safety.
As they struggle to survive, the two awaken extraordinary abilities and grow stronger with every battle. Together, they carve a bloody path through swarms of mutated monsters, becoming an unstoppable force. Yet survival inside humanity’s last refuge proves just as dangerous. When powerful figures within the base set their sights on Ye Xuan, he refuses to be bullied, striking back without hesitation. And every time trouble follows, his seemingly emotionless roommate appears at his side, silently helping him deal with the consequences.
Their unspoken bond deepens amid countless life-and-death battles, but an even greater conspiracy is taking shape within the base, forcing them onto separate paths. By the time they reunite, the apocalypse has transformed them both. Cutting through mountains of corpses and rivers of blood, his roommate fights his way back to Ye Xuan, making one unwavering promise:
“Ye Xuan, as long as you’re by my side, there is only one way you can die.”
“So keep living.”
The protagonist starts out relatively weaker but gradually grows into a formidable powerhouse alongside the male lead.
