My Opinion: 276 pages, $2.99, Available on Kindle Unlimited

The fourth book in the series continues the slice of life adventuring and power progression. The main character (MC) is pretty overpowered at this point and the scope of the story gets bigger dealing with nations, and even planets as the MC travels. The big draw for this one is going to be that the MC becomes more villainous in the story all with the ultimate goal of saving his wife who was comatosed at the end of the last book. He needs to gather a massive amount of Sin points to convert to other power sources to upgrade his system. It was rather neat seeing the MC travel to a planet, learn the culture, see all the world building, and then have him tempt, bully, or intimidate his way into getting people to sin and exploit the system.

The story still has Idle System progression mechanics but besides the chapters dedicated to it, the novels feels more cultivation sometimes. Though you don't see the full character sheet often, there are semi regular updates on certain skills that the idle workers complete, and information on just how much life and toxic power the MC is gathering.

Overall the novel is good. It does wander from the main goal regularly with the MC going on these nostalgic side adventures, but that’s pretty normal for a slice of life story. I think the darker tone of the story will keep fans of the series entertained.

Score:  7.5 out of 10
