It was the worst starting point, but it means nothing for him, the original author.

That’s the reason why I have the knowledge of the original work]. Using the original work knowledge cheat to change the fate of a mob that even left the hero in awe, he’ll be an unparalleled character in this world——!
last few chapters are rushed it feels like author wanted to finish the story as soon as possible 
I love the series they should make more like this or where the mc gains the power of a god yet gets sent to a world where gods are just stronger ants.

A roller coaster of a manga that doesn’t make any sense with plot twists every chapter. maybe 6/10. Bland plot and story. good range of cast characters though alot get tossed aside later in the story.
the story is too bland for me..like there is no suspense plot just predictable outcome with easy going mc..
Cliches and tropes are okay with me if the story is good…how is the story folks?
Well then mc accomplished his goals
MC:
the king seeing this is just like damn this kid is scary
all as keikkaku
More of that please
Mc
Manga titles get longer every day

Alternative title : TTTT – Typical Transmigrated Trash Thug.
A.K.A. : (T﹏T), for the fans 
Like already said this story is rushed at the end. Before that it was quiet a nice read, the art is nothing special but does the job. Something I personally didnt like
