Lin Yuan was very satisfied with the divine kingdom ability Toxin Spirit Control that the Ancestral Contract Brahma Snake had obtained after reaching the Holy Spirit level.
Toxin Spirit Control could be regarded as a defense-type and amplification-type divine kingdom ability. Apart from Snake Coiling Defense and Soul Forging Armor, the Ancestral Contract Brahma Snake's current defensive abilities were only Life Prolonging Shedding and Soul Box of the Ancestral Snake.
No matter how strong the snakes controlled by the Ancestral Contract Brahma Snake were, it was the core of the snakes. If the Ancestral Contract Brahma Snake was in danger, the entire snake group would be destroyed.
Among these four defensive abilities, Life Prolonging Shedding could indeed save one's life. But every time it was used, it would cause the Ancestral Contract Brahma Snake to enter a weakened state.
