I have read the first 30 chapter and can say that it has good writing quality and stability of updates. The story development and character design isn't really for me. While it is decent, I find it rather too generic (good guy trope) and I found his reincarnation rather useless, maybe there will be a reason for that later but for now, all I see is a somewhat obedient little boy in the MC. He had merged with the previous soul, yet there is no fear, or worry, or even acknowledgement that he was killed. Where is the caution, he goes around worrying about his mother, yet why is that? He just came into this world and the memories doesn't seem to affect him, can you generate affection quickly for someone this quickly? If he does have memory of his life as prince then why is there no fear or even a thought about his murder. What is the reason that he wants to get strong? Is it revenge, to protect his loved ones, I still have not found a reason for him or the story. I see no tension or reason to follow the story, his sister seems far more interesting.Usually the environment of fighting for thrones make the characters mature, yet the MC seems to lack that. While the story seems to check most boxes I really did not get an interest in following the MC's story. His origin not really that interesting, his circumstance he seem to not care, his cheat and bloodline a bit generic. I expected more then this from Invincible Corruption Manual. Writing Quality - 5 Stability of Updates - 5 Story Development - 3 Character Design - 3 World Background - 4The total score - 4
