Nightfall

In the ancient world lies a prophecy: Upon the arrival of Yama, the world will be thrown into Chaos. In Chang An, capital of Tang - the most powerful empire in the continent - General Lin Guangyuan's Manor was unjustly massacred by a great general. The sole survivor who managed to escape amidst the incident was a young boy named Ning Que. He survived in the wilds through his wits and committing murder. One day, he dug out from a pile of corpses an infant girl, Sang Sang. Years passed, and since that day the two of them became inseparable. Ning Que joins the frontier military and Sang Sang, now a scrawny, and malnourished child with a mysterious illness, becomes his hard-working hand maiden. In his quest for revenge, Ning Que hones his fighting skills and is determined to become a cultivator; a powerful warrior trained in martial and mystical arts. However, several years of effort prove that Ning Que has no talent in cultivation, and his only hope left is the Tang Academy, an influential academical instituition within Chang An, and also home to powerful and mysterious cultivators. Eventually, Ning Que becomes part of the entourage of Princess Li Yu as she travels back to Chang An, which leads him and Sang Sang to many wondrous adventures. Will Ning Que succeed in his quest for revenge, will Sang Sang's illness be treated, and will the ancient prophecy ever be realized? This is an epic and legendary tale about Revenge, Love, Immortal Cultivators and Gods.
