The Bride of Nirvana.

Once every 144 years, Nirvana demands a bride.
Once every 144 years, the King of the World chooses... and none have ever survived.
Hua Yong is that king - immortal, feared, and ruthless. Protector of Country V, a man whose power is unmatched, whose presence commands fear and obedience. Twelve omegas have come before him, each claimed, each... allegedly destroyed.
And now, the ritual calls again.
Gao Tu never intended to step into this world. Hiding his true identity to work as a beta for his sister, he knows nothing of the ancient rules, nothing of the power that awaits, nothing of the man whose shadow stretches over the entire country. But the cruel games of fate - and of his father - conspire against him. Tricked and sent to Nirvana in place of the chosen omega, he finds himself alone, unprepared, and in the presence of a man who could burn him alive with a single glance.
Hua Yong is cold. Merciless. Legendary. His reputation alone could kill, yet beneath the darkness lies a fire that no one has survived... until now.
In the days leading to the ritual, Gao Tu must navigate a world of secrecy, temptation, and peril. One touch, one stolen breath, one forbidden glance could awaken a heat neither of them can deny.
Will Gao Tu survive the legendary King of Nirvana?
Will he be another lost bride - or will desire, passion, and an impossible connection ignite a fire that could shatter the ancient order forever?
Treachery, obsession, and forbidden heat await. One mortal omega. One immortal king. A ritual that decides life, death, and everything in between.
