After chapter 742 the mystery regarding the disappearance of the protagonist's mother intensifies. After destroying the initial enemy in Country R, the real enemy appears. The enemy threatens to destroy the entire planet if the world's governments and population don't submit to him. The MC, of course, saves the day and then travels to space and saves a bunch of people while travelling to the moon (or something). Then she opens an academy and whatnot.
The author seems to forget that the female lead is a lot older than her fellow peers after reincarnating back to the age of six. Mentally she's supposed to be around 15 years old in the beginning and by chapter 82 she's supposed to be 22 years old, but as a reader I don't feel that matureness at all, no growth (only psychically). Actually I sometimes feel that female lead regress and acts unbelievably immature for her otherwise supposed age. Normally I'm a fan of time skips, especially because the novel isn't very long, but if the author wants to do time skips, at least make sure the characters development follows as well.
The protagonist wants a divorce, but before divorcing she wants to prove to her cheating soon to be ex-husband that she is more than a neglected and ignorant housewife. As such she goes to a company for human resources, but somehow that building turns out to be a guild from another world and after a really confusing and incoherent conversation, she is suddenly in another world after leaving the building.
