Could be better if not for the poisonous plots with Arasaka family.

The main world is probably Marvel, with a higher limit and more freedom. it is marvel lower limit, even the lowest marvel world i have ever read; where there is no captain america, iron man and spiderman.. i read till 426 chapter and mc is still sick. And i sick reading this thing..

there is no creativity on this novel... even though he is 'genius', all his jutsu just copy paste other people jutsu and what i hate the most author is FORCING him become DUMB. even when he want to resurrect from impure world reincarnation with intact main body but because pure world attraction his soul cannot go far and enter his body instantly, he still need spiritualization jutsu from kato dan. but there is easier solution like hugging your main body with zero distance or enter your main body mouth by using transformation jutsu/bullsh1t.. even after he get that kato guy jutsu, he still need to sacrifice part of his soul because he can't modify jutsu, but if you think carefully there must be someone who fail to practice this jutsu whose full soul go outside body and the body die. so all of this is just pure nonsense.

this story is about if MC is Scum Young Master Subordinate. T he most critical problem on this novel is author make the AI and MC dumb for the sake of plot. sometime he is above average people IQ, but sometime he is so stupid that the whole story dragged down. it's like MC fell over his own feet, but with AI as a cheat mc is using wheel chair, so it's just impossible for mc making brainless mistake. forcibly making AI and MC dumb for the sake of plot/word, is just frustating.

99% TRASH. Unexpectedly, every time he harvested spiritual fish, he could get a light ball reward. [Harvest an adult big black carp, reward a low-grade water arrow talisman! ] [Harvest an adult iron-bone crab, reward "Gengjin Sword Art"! ] [Harvest an adult longevity turtle, reward turtle longevity pill, extend life by 20 years! ] This kind of cheat where mc harvest something and get ITEM, is just trash after you read 1 novel with this cheat. especially when he get something BORING like low-grade water arrow talisman, Gengjin Sword Art, and turtle longevity pill. if author really cooking than he should give mc something out of cultivation world, like fantasy world, magic, sci-fi, game, movie, manga, gods, horror/ghost, devil etc. but NO, it's just copy paste TRASH.

CONFUSING MESS TRASH!
