Review Detail of Nyxio in Reincarnated With A System In A Cultivation World

The author needs to go back and fix his early chapters. He promises that MC improves later but it is of no use if a new reader gets too frustrated with Mc's lack of IQ. MC behaves like a retard and rages on the system like a Karen. There is no character development over the 90 days of training and the MC is still the same. He is confused about cultivation and reincarnation but later says that he is familiar with reincarnation novels. After he took a long time to understand stat points(which I will come back to) he is still confused about Skill points. How difficult is it to understand? He also impulsively decides to dump stat points in one stat just to get out. Why is he in a hurry to get out? What if there is danger outside like how the system mentioned? After getting outside he again ranges on the system for not replying to him when the system clearly said that it is updating. This was too stupid for me to continue. Please tell me that he is suffering from a debuff on his IQ due to his young master title because otherwise, his stupidness will be hard to explain. Don't say that he is new to the world and in shock. Shock lasts only for a short time, he should be able to adapt faster as a self-proclaimed nerd, plus it has been 90 days. The main reason I quit is because a reader who has read ahead said in the comments that this character and behaviour of MC persists for many more early chapters.
