The First Book by Yu Xiang Chi Fan

Yang Ye is an orphan from Blue Star who unexpectedly transmigrates to a fantasy cultivation world, where he becomes the youngest disciple of Wen Qingwan, sect master of the Qingxuan Sect in the Canglan Realm.

He has three senior sisters, each with her own charms. Wen Qingwan brought them all to the Qingxuan Sect when they were young. They have extraordinary talent, but their fates mark them as doomed, ill-starred loners.

According to the blind old master of the Ting Tian Pavilion, Yang Ye will live only until the age of eighteen.

Still, Wen Qingwan adores him, and his three senior sisters have doted on him ever since childhood.

On his eighteenth birthday, he awakens memories of his previous life.

He also binds to the [Cultivation Critical Hit System].

As soon as it binds, the System triggers a ten-thousandfold critical hit, granting a generous reward, but only if he completes a nerve-racking mission.
