Jiang Chen really wasn't afraid of Great Emperor Shura in a battle of formations.
In terms of formations alone, Jiang Chen possessed innumerable formations. His understanding and comprehension of formations were absolutely higher than Great Emperor Shura's.
After all, Jiang Chen had inherited the Ancient Crimson Heavens Sect's formations. Even without the sect's heritage, the things he'd learned in his past life were still astonishing. Although he hadn't systematically studied formations in his past life, the heights of his past life were obvious.
In this life, he'd assimilated the formation heritage of the Ancient Crimson Heavens Sect and obtained the Earth Bodhisattva Orb, the sect's ultimate treasure.
In this way, his knowledge of formations was naturally astounding.
Jiang Chen didn't plan on helping Great Emperor Peerless cheat. He didn't have the time to do so either. The dao of formations wasn't something that could be learned overnight.
