I'm not sure that the author has actually dropped this series yet. They haven't said anything about it. Based on how season one ends and what I know about the plot from the game, I know that they were definitely intending there to be at least a second season. The comment section on the raws is still pretty active with people saying they're waiting for s2 even though it's been like 10 months since the last chapter was posted. So will this manhua ever get a second season? who knows. maybe not. I think the author may have been having some real-life issues which is why the ending of s1 feels very rushed and why they've been on hiatus for a while. For now, I would consider the manhua "completed" but it clearly has more story that goes beyond what happens at the end of s1.
If you're interested... The story is technically still continuing, just not the story of this manhua adaptation. The mobile game gets story updates about every 2 or 3 weeks. Actually, there was a new story update just today haha. If all the story in the game were to be adapted into the manhua and it had the same pacing as what's in it so far... then this series would probably be over 700 chapters, so there's definitely not a lack of story that's available to be adapted lol.
