System, Your Little Disciple Is a Dragonkin

Before dying, the disciple learned that a scumbag had deliberately led him to misunderstand his master all along. With the System’s help, he returned to the time before he joined the sect, determined to get a second chance and make amends. Unexpectedly, he ended up carrying his master’s child. His master had other astonishing identities, and the disciple’s own background was impressive too. Prepare for surprises! The disciple is an adult.

Two male leads, sweet romance.
