The tale speaks of three Buddhas who had received the Buddhist Law from Amitabha Buddha and headed toward Water Curtain Cave to destroy the Ten Thousand Immortals Formation and eliminate members of the Demon Tribe.
On their journey, Mana Accomplished Buddha spoke, "This Ten Thousand Immortals Formation was devised by the Tong Tian Sect Master in ancient times and is extremely formidable. Shen Bao has only grasped its surface, not much of its essence. Even so, it's not something that ordinary people can break through. Thankfully, we know the mysteries within it and have received a magical treasure from Amitabha Buddha. Breaking this formation should not be difficult."
Filled with joy, Dingguang Delighted Buddha sneered, "Tathagata was once the chief disciple under Tong Tian Sect Master but failed to learn the method to arrange this formation, naturally, he couldn't break it. This time, as we break the formation, it will be like slapping him hard. Heh heh!"
