You're wrong the author said in her weibo she's planning on continuing it after song of the sky walker. I also heard she's meant to get the rights to changgexin in 2025 so it makes sense why she's gonna finish that first.

she also talks about changgexin from time to time on her weibo
I had a quick nosey. Some people on reddit said she's won the copyright lawsuit as of now and has confirmed to people on weibo she would continue after her skywalker manhua. I tried loading up her weibo but its been uncooperative. But, it's looking good, when I was last on her weibo (2024) she would post sketches of the characters from time to time showing she hadn't forgotten them :)

Been following this series way before it was uploaded on this site, still one of the best series which definitely deserves not only an animated adaptation but a life action one too. Add this to the list of series that stayed in hiatus for several years, the fans are strong and determined to so see a worthwhile ending
