The System Asked Me to Accept Disciples, but All of Them Are Monsters

Introduction: [Group Pet] + [Warm Master] + [Cultivation] + [Easy] Gu Shenyan traveled through the world of immortal cultivation and was bound to a strange apprenticeship system. The system lied to him and said that as long as he recruited ten apprentices who met the standards, he could have a glimpse of the top of the avenue. He searched for a whole year, and finally found the first one at the gate of the Duke of Qin's mansion. [Innate Taoist body, genius of swordsmanship]...​ Gu Shenyan was overjoyed, thinking he had found a treasure, but unexpectedly someone had changed the package. He held the dying Qin Shuangning in his arms and knocked down the Duke's Mansion with a sword: "If anything happens to her, I want you to be buried with her whole family!" Unexpectedly, this is where everything begins...​ A new apprentice, when he was practicing in the middle of the night, there was thunder in the sky, and a vision fell from the sky... Gu Shenyan looked at the shocking entries on the system panel: [Destined Villain] [Reincarnation of the Immortal Emperor] [Rebirth of the Demon King]... He took a deep breath and suddenly felt... Is there something wrong with this apprentice?
