My Sister is Tianzun

My Sister is Tianzun, also known as MST or 我的姐姐是天尊, is an urban life novel that follows the story of a wealthy daughter who suddenly finds herself inhabited by her long-lost elder sister from the immortal world. The unexpected situation leads to mistaken identities and a unique relationship that blurs the lines between family and lovers. As Chen Ze navigates this new reality, his journey towards becoming an alternative son-in-law unfolds amidst themes of cultivation, fast cultivation, and the classic weak-to-strong trope.
