Review Detail of Reached_The_Apex_ in Endgame Restart

This story has no premise and is otherwise just something to waste your time on, the author conveniently throws so much shit in your face in hopes you don't realize the plot is built upon a mountain of sand. The mc dies and reincarnates so what does he do? saves his sister as expected since thats the synopsis. However, after that there is no future knowledge use or skills that he has acquired to put him above others. He is mediocre beyond belief, the plot is slowed even more by author writing useless characters and poor decisions that kids would make. In the past 100 chapters all mc has done is save useless side characters, killed a crab, somehow decided to combine his crafting skill with an ice skill to get ice and fire that allows him to detect killing qi and summon shadow spirits?????? what the fuck? The last thing to consider is the mc died after a decade or so at level 7? but after being reincarnated everyone is already level 5 within a few months conveniently glossed over by "this world is mutating fast" oh okay, well fuck me for wondering. terrible novel with no real plot
