Transmigrate to Xia Lan and Protect Jiugongling

Warning: I won't change the main plot. I just want to make the story a little less regretful. If you don't like it, stop reading. Please don't leave malicious comments! I'm sensitive, so read if you want to, and if you don't, then don't! Don't come here just to make your presence felt. If you want it done your way, write it yourself.

I transmigrated into the world of Xialan. Those heroes who sacrificed themselves for everyone, Zuo Shi, Xiang Li, Po Zhen... Now that I'm here, I'll do everything in my power to change your fates! You must all get a happy ending!
