However, it didn't end well for Go Okrim's brother either—his own crystal core was ripped out by the other zombie in the final moment of the battle. Even though they managed to reinsert it immediately after the fight, it was already too late.
Go Okrim's zombie brother took his own crystal core out and placed it in Go Okrim's body.
In the final moments of his life, he was still thinking about Go Okrim, afraid that without his suppression, the other zombies would pose a threat to his human brother.
"With my brother's crystal core inside me, I can control some zombies as well, but I can't suppress the whole county's zombies like my brother could." Go Okrim looked at Kim Haru. "Turn me into a zombie. Once I become a zombie, I'll be able to absorb my brother's crystal core, and I'll be able to control more zombies. I'll follow you, do whatever you ask me to."
Kim Haru chuckled. "If that's the case, why shouldn't I just absorb the core myself?"
