Ending is just excuse for dropping this novel by author. He lost in his loops and finally decided to end this
MC doesn't answer affections of many women because of his childhood girlfriend. When she come to this world he doesn't confess to her but just protecting her it's so hard to say I am... and I love you he written a letter but wonder what happened? It was intercepted by lame hero. There will be harem but we must wait another 100 chapters for MC and his love interest meet and he grow some balls to confess to her again. 183 chapter stil no confession (I mean second confession because MC tried once (Failure)) Maybe in 20 volume he will confess or author will drop this novel he will be not first and not last author that did something like this.
Everyone is bulling him... And what he does ?Completely nothing...
Story developing well to 200 chapter+ and then author decides to end the story faster and just skip to the end with some plot armors.
Author made his skills like this while others learn how to use aura and other sh*t he just combine skills and get power ups
When he left his girlfriend he feels guilty about this and think about her I don't know that he will continue being like this while 2 girls basically bitching around him we'll soon because there is only 80 chapter left or so with pace of translation mb in 2 years :D
For example MC used 1 year to revive the Tree of life he even made second one... Enemies just didn't paid attention to these things at all and after he made. Few trees of life and gathered elfs around they finally (I say finally because it took some time) got that their plans were destroyed by him. We have another thing converting guns to items 3k for super duper sniper riffle and he kills the corrupt examines like rabbits... Ohh rlly we don't want to influence the time flow but why not give MC power to bring technology to this world ? (why not?)
