Chaos Energy was the energy that first formed at the beginning of the universe. It contained the most primitive, oldest, and most original Great Dao Law and order talisman scripts.
The energy increased nonstop inside of the Sky-Devouring Snake's body, and its demonic immortal law increased nonstop as well.
Bang, bang!
The Sky-Devouring Snake's internal demonic nucleus cracked, as two crisp sounds came out, and it directly reached the peak of the demonic immortal realm.
Qingfeng saw that the Sky-Devouring Snake had already reached peak demonic immortal with just a yellow bean-sized chaotic stone, and he became overwhelmed with excitement.
Hints of bright light appeared in Qingfeng's eyes, as he secretly thought to himself, no wonder this is the rare treasure of Chaos Era, it truly is too powerful.
