The Spinal True Feather's Hong Yu carried a blood poison, while its White Feather was sharp and could be used for long-range attacks. This was something Yang An had always known.
However, he had never used the Hong Yu aspect before, only deploying it out of necessity against the giant bird just now.
Seeing the giant bird's miserable state, Yang An was momentarily confused, thinking something had gone wrong with the creature's Immortality.
It wasn't until he saw blood erupt from within its body, transforming into a corrosive toxin, that he understood.
The wounds he had inflicted on the giant bird with Hong Yu had left a blood poison inside its body.
'What Yang An hadn't expected was for this blood poison to be so potent!'
After all, the giant bird possessed Immortality, which meant conventional powers couldn't kill it.
