Review Detail of Saarlink in Returning from the Immortal World

I love the beginning of this novel. Read it more than once as I caught up to the chapters that had been translated. The MC is what I would like to see in an MC, kind but capable. He is not murdering people and their families (though later he does a bit of the stabby stabby but it is justified well and generally done in a clever rather than just evil way). I eventually stopped when the author decided to go a bit too overboard with his terrorist plot and have heard that the harem gets a bit out of control later on too. I solidly recommend the first 450 chapters or so of this novel as they are by far the best take on this situation I have read.
