If youre into those ‘it doesnt make any sense’ type then this is not for you.

This is not just a plain time travel story. To understand the story better, its also best to know that this is one of those story with timeloops & alternate timelines. Similar to that of Oriental Odyssey.. & yes it can be very confusing. Lemme try to elaborate...

1st timeline.. Adult FengXi dies. His hateful spirit was born, Eryu. And met an orphan WenXin on a war. (explained in the later part of the story when FengXi met Eryu) Timeloop..

2nd timeline.. youngWenXin grewup with Eryu became a general who fought against LuYuantong. In that timeline, both WenXin & FengXi died at Zhuming ( ayear after he reached the highest post) ( 1st episode) Timgeloop & time travel..

WenXin went back to a timeline where she was a kid, FengXi was an adult and Eryu hasnt been born yet. Here we can see that after assuming identity of DongYue, she was still connected to young WenXin but adult DongYue is not at all related to young WenXin. DongYue could get hurt but young WenXin remains unaffected, while DongYue feels whatever WenXin feels. In the drama, Eryu met young WenXin after a war where we can conclude FengXi also died around that time. With that, it can be concluded that DongYue & Eryu’s mission was never to stop the war but to keep FengXi alive. Both of their existence depended on FengXi’s existence. FengXi didnt die, Eryu wont be born & wudnt meet young WenXi. WenXi wouldnt re exist as DongYue. When they succeeded in keeping FengXi alive, the original timeline was restored, fate was changed. Just back to Adult FengXi & young WenXi. No Eryu. No DongYue.
FengXi & DongYue being not recorded in the journals kinda seals off the loop. It was just confusing as to why everyone remembered her, in oriental odyssey they lose their memory. But yeah.. novelty

Young WenXin stayed by the 3rd prince / king side & was already studying martial arts. So it could be preparation of her being the general. Open ended

Undisclosed period of time after, a lady, similar to DongYue’s figure appears. Can be the grown up WenXin or can be DongYue herself, we’ll never know

I fell in love with the Male Lead. Im disappointed with the FL being so distrustful towards the ML. Her only redeeming point is that she’s pretty, strong and good with martial arts. Just the same i love the story. Every character was relevant & played well
