The reason why the original Akatsuki's Time Sea Series 2 had stopped updating was probably because the storyline or character development needed more in-depth exploration. The storyline of the second series of the Yuan Xiao Time Series was very complicated and required more time and energy to narrate. In addition, the series may face copyright issues and may not be able to continue updating. However, if you are interested in the second series of the original Akatsuki Time Sea Series, you can read the relevant chapters or find other sources for the latest information.
