More precisely, Daniel had two guesses about the changes
According to his first guess, he was not reincarnated in the main world of the novel itself, but rather in a parallel world similar to the main world of the novel.
In such a case, all plot changes that have happened so far and will happen in the future can be rationalized and related to the parallelism of this world.
Daniel's second guess was a little more unbelievable than his first guess, but according to Daniel, it was more possible
According to his second guess, the plot is changing because fate wants to weaken him, why does fate want to do such a thing? Well, the answer is simple
According to the system, fate could not see Daniel's future, and his life was not determined by fate.
Naturally, fate itself easily notices an anomaly like Daniel.
What was Daniel's role on the other side? He was a villain who should be killed by the protagonist!
