Yan Yuebai, the great disciple of the Yuntian Sect, is the pride of the sect in front of others, unrivaled in his class under the Heavenly Vault Fan, and an astonishingly talented formation master. But behind the scenes, he is the Holy Son of the Demon Clan - a shocking undercover agent lurking in the three realms. He originally thought that as long as his identity was not exposed, he would be able to escape unscathed.
But he forgot one thing: being too good and knowing nothing about his appearance.
In the daily life of the Yuntian Sect, there is hidden the obsession of the junior brother to get closer step by step; the master has a different look in his eyes; at the bloody coronation ceremony in the imperial city of Yan Dynasty, there is an emperor who will never forget him; in the demon world, the fallen demon emperor secretly remembered his appearance.
On the day when the identity is exposed, love and hate grow at the same time. The Three Realms War is coming, and he sacrifices his life to break the catastrophe, but only four people are left to face the days without him alone.
…
In the secret realm, the person in the coffin slowly wakes up——
"I'm obviously an undercover agent, why did I become Bai Yueguang?"
