My level is stuck at 8~ㅜㅜ

Slurp! When your Sanctuary level is blocked, the basic approach is to meticulously examine the prerequisite building conditions, hmph! Clearly check if you have enough resources and stars, and if your laboratory level isn't lagging behind. As a kind piece of advice, I recommend re-examining your quest log to see if there are any missed milestones, hmm!

If you take your time and play calmly, you'll level up in no time!

Hmm.. are you working on the Cathedral upgrade? I recommend using maximum acceleration and joining a top-tier (Korean) guild! You'll be able to upgrade quickly with a lot of help!! Good luck! 💪💪

Just upgrade it according to the conditions for raising the cathedral, the important thing is to join a guild. What could be the reason it's not going up at 8? If I knew, I could give you more specific advice ㅠ
