After a while the author skips over the system giving rewards and a dozen or so chapters later it disappears altogether.

Honestly I don't get the hate this is receiving, it is nothing new or groundbreaking sure, but honestly it is pretty entertaining. It uses the basic formula of waste MC+killing others to grow stronger fast, and he is usually either killing or on his way to kill, but the writing is decent enough to make it entertaining. The names of the realms are messed up quite a bit like it saying body forging when it means blood moving. It can be annoying, but I don't personally believe this work is deserving of one star, probably a 3. If I take into account all the garbage being put here lately I could even consider going for a 4.5/5. Overall a decent work when like me it is the only thing left that interests you that you haven't read.

Started out pretty good, later it changed and started to suck.

Didn't get too far and where I got it wasn't bad at all, the only problem for me is that this wasn't quite my cup of tea. A fine work overall, just not what I was wanting to read.

Starts really good but once we move to the new continent it becomes worse, fights drag on for nearly ten chapters, MC starts acting out of character an arrogant young master pops up out of nowhere to start messing with the MC over a girl that the MC clearly has zero interest in. Honestly the first hundred or so chapters were 5/5 later chapters were like 2/5.

The system last fully appears in chapter 19 and afterwards only getse mentioned whenever the MC needs something or the author wants to add something and can't think of a good reason. The first arc is relatively boring but I wouldn't completely recommend skipping it as there are some things in it that would be important in later chapters. Overall relatively fine read.
