Ready, Aim, Fire: Book 6 Air Booster Online (Sci-fi LitRPG)

by Mike Lin

As Jace progressed into the higher hours of World 5, he realized that no matter how much he upgraded his systems, there were always enemies waiting to tear them apart. Twenty mantises were no joke, and his current setup simply couldn’t handle the sheer number of threats he was facing.

To break through this progression wall, Jace needed something revolutionary, something powerful enough to change the rules of the fight.

But what system could make that kind of difference?

this series is pretty entertaining

Fun story high entertainment. Reading these books pretty fast.. one thing thoughhhhh! Jace has zero common sense… like the answers to a problem can be basically slapping him in the face and instead of being like “oh yeah, duhh” it’s like a major breakthrough epiphany. This character is sweet and charming but damn he is an incredibly high functioning dumbass. For someone supposedly amazing at battle tactics he could use just a smidge more common sense.
Either way, im still enjoying this series a lot! Can’t wait for what’s next!
