Twin Reflections, Thunder Spirits

High above the ninth heaven lie the Celestial Realm's Nine Heavens Thunder Pool, where immortals temper their bodies with ultimate thunder; the Star-Gazing Pavilion, which holds ancient secrets; and the abyss of Mount Mulan, where gods and demons lie buried. To consolidate his rule, the Celestial Emperor secretly advances the "Heavenly Thunder Project," gathering the source of thunder through people born under special destinies. Xi Ying'er is the key vessel in this plan.

On her wedding night, the crown prince Qing Bo, once her childhood sweetheart, drives the Sword of Immortal Slaying through her dantian. "Junior Sister, your blood makes the perfect wedding wine for me."

Yet she clearly sees the reverse scales beneath his wedding robes devouring the bride's soul, while deep in his golden eyes is the boy who took a tribulation for her at Mount Mulan three hundred years ago.

A fragment of a broken jade slip reveals a horrifying truth: the groom's true name is Xu Xiao, the first to fall into demonic corruption, and the heart beating in Qing Bo's chest holds half of her life soul.
