I Am Also a Great Immortal

What? Am I also a great immortal? Why didn't you tell me earlier? I was scared to death just now! The key point is to cultivate immortality in this world? Have! Is the protagonist an orphan? Right! The protagonist has a cute little sister? That's right! Should she be pampered? I have the final say! "Do you want my sister or me?" Countless beauties have asked this question in anger. What should I do? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
