Hyun-soo became an alien monster like Ryan, the guardian knight. He defeated the mutant monster of the underworld boss and protected the rest. However, after he lost his rationality, he kept saying the word "home", which was his last wish. Li Yinhe has also changed. In order to block the uncontrollable Hyun-soo, Li Yinhe chose to die with Hyun-soo at the last minute.

The rest of the people slipped to safety through ropes and were placed in areas protected by the army. In the rain, a cocoon appeared on the messy roof, and Hyun-soo came out. He's not dead.
