The Alternate Keeper: An OP MC Fantasy Isekai Adventure

Retrogression Keeper #2

by Jonathan Brooks

The Lone Keeper has an entire world to protect, but that world is about to get a whole lot bigger…

After discovering that his presence in Derelya has a detrimental effect on the ambient energy if he stays in one place for too long, Bax is determined to keep on the move. Forced to go solo after his Party abandoned him, his entire goal is to learn more about the world he is duty-bound to protect, while also attempting to gain the support of the population – all despite being one of the despised Keepers.

On his travels, he stumbles across an individual who is just as much of an outcast as himself. Teaming up, Bax hopes to one day help the new addition to his Party get stronger and potentially even become another Keeper to join him in his efforts to save Derelya from the monsters that threaten it…

…until a Task to defeat a Remnant goes sideways. Despite eliminating the powerful monster, his new Party member is unfortunately killed soon after; in an effort to get her back, Bax accidentally does something that will change the world – and the entire Retrogression System – forever.

This story contains an overpowered main character, LitRPG progression mechanics and stats, and isekai/portal fantasy elements. Contains no sexual content or harems.

Bax it off to a new challenge because of a mistake and that he care for his friends. His planet might be the only one in this universe, but because of his mistake he found another, and those residents wanted more land, so they attacked his world and took his friend. What is a good guy to do but go after them. I like how everyone underestimated him because of his shown level. He was able to find another ally to help him with answers on his quest. I hope he is up for his new challenge.

An improvement over the first but hopefully the rapid power rise means this is only a three or four book series. Since the protagonist can just *splat* any enemy there isn't any tension and with the main secondary character from book one put of of action early there isn't much to say about characters.

Great OP story line

The story line is so OP that it's a standard type thing but it has other OP carters that basically balances it all out so lots of action and twists with different ways of using powers that it makes it interesting to read and follow, cant wait for the next book
