Three Hundred Years of Longing: Bu Jian Shang Xian San Bai Nian (Novel) Vol. 4

With Xiao Fuxuan at his side, Wu Xingxue survives the ordeal of recovering his memories--only to find himself with lingering questions. Their search for answers leads them to an impossible place: another Urbs Caelestia, where history repeats in warped reflections. Amid the fractures, Hua Xin's truth surfaces, shaped by the devotion he carried, the choices he cannot undo, and the reckoning that awaits him.

To complicate matters further, the reckoning is interrupted by Tianxiu and Rex Spiritus, who believe their world is the core reality--which makes Wu Xingxue and Xiao Fuxuan a threat.

Despite all opposition, Wu Xingxue is determined to destroy the Heavenly Principles for good. But when reality threatens to collapse under divine wrath, will the love he shares with Xiao Fuxuan be strong enough to save what remains?
