Reincarnated with a Mafia System

Poor explanations and reasoning behind characters motives for their actions, author too lazy to actually research or know anything about how actual criminal organizations work leaving this mediocre mess unreadable for me, author cannot even fix his gun terminology or research anything about them and its a mafia novel for christ sake and gangs use guns of course, author again and again keeps putting unrealistic scenarios in the plot like the part in chapter 3 where the MC somehow magically gives a man a concussion and instantly knocks him out punching him in the front of his throat, scenes where childish scenarios play out like when he recruits the ex boyfriends girl with literally one sentence and doesnt explain anything as to how the **** its normal for this chick to do this without any explanation or incentive, over all bad character design, story development, havent updated anything for a month, writing quality sucks, and there is practically no world background just from me reading 4-5 chapters before the story quite literally became unreadable for me on account of how retarded it is.
