After Cleia summoned the Curse Spirit she controlled, she sat cross-legged on the Six-Eyed Black Python. The Six-Eyed Black Python absorbed a stream of exotic energy from the void and then transferred it into Cleia's body through a certain link. A shroud of black smoke enveloped Cleia, making her appearance extremely sinister.
Seeing that he couldn't assess the specific power of the Six-Eyed Black Python, Udi withdrew his gaze and prepared to practice the Violent Bear Swordsmanship. Inwardly, however, he was secretly astonished, thinking,
"A Level 5 Curse Master can control a Curse Spirit with a Biological Level reaching Level 7-8 strength?"
This was only based on its aura. If the strange traits of the Curse Spirit were considered, even a human professional with a Biological Level of 9 might not be its match.
Level 9 is already the peak of the Middle Tier, and Level 10 above that is the High Tier.
