Review Detail of ViciousHandler in The Ultimate Transmigration {Completed}

Novel idea is good but poorly executed. Common!!!! A child under 2 year old doing assassination job?? Be realistic to the anime norm here!! Also the status contradictory is too much!! Fighting Hisoka and barely winning but his leader board and status is way stronger?! Then saying he is 12 years old and next few paragraphs having status showing that he is 6.5 years old? And then after waking up from fight with Hisoka at the hunter exam status and leaderboard shows he’s even stronger than Netero?? Like wtf??? Too much inconsistent here. Author needs to review and rewrite.
