Long pain is worse than short pain, the mysterious creature's neurotoxin has already seeped into the membrane of the wings. Even if the residual mucus on the surface is burned off with flames, it's useless...
The pain was indescribable, just like amplifying Wang Xiyi's pain perception thousands of times, then carving into her flesh with a small knife dipped in concentrated saltwater, one cut after another. If this pain continued, not only would Wang Xiyi be unable to fight, but there was also a possibility she would faint from the pain at any moment.
The black dragon's body has a strong regenerative ability. Even cut-off wings can regenerate, but for such a completely severed "serious injury," it would take at least two or three days to grow back.
At least in this battle, Wang Xiyi had thoroughly lost the ability to fly.
