Try checking Shiraori's thoughts in chapter 71.2. She stated that she's been used to making threads that there is nothing much to observe anymore, because her threads are the only thing she can use with her godlike powers- currently. Also, before she was very dilligent ofcourse because there is many skills she can learn and needs to learn. Then, after the ascension, she can't use the system anymore which is like the database for all her skills and stats. My point is that the system helps her learn skills and train them. Now as a God without the system, she can't learn and level up those skills anymore. Based on the current flow of her life, she is trying to regain her skills but have no clue to do so because there is no system to help her anymore.
PS: This is just my personal statement and my current understanding of what is happening based on the manga. ╮( ̄▽ ̄)╭
It's so boring... It's almost entirely traveling, lazing around, not doing anything. It's like the manga turned into slice of life. Also where the hell did our MC's personality go? She was so dilligent (by necessity but still) and proactive. Exploring the dungeon and after that the world. Even helping humans to the point she came to be known as some kind of protector to a town.
But now? She's a lazy bum who just wants to sleep, read, and eat. She also complains about being weak but does almost nothing to try and learn about her godlike powers.
