I really appreciated the Naruto arc and the way the author developed Tobimaru's character; it was nearly flawless, aside from the minor inconsistency with the MC's creation being casually left on a desk. Initially, I didn't realize it was a time skip story, so the rapid pace caught me off guard. The time jump was substantial, almost two decades, which might explain the MC's extraordinary abilities. However, the reliance on a time skip for character progression didn't contribute much to world-building. Overall, I enjoyed the read.
It seems the author initially intended to include arcs based on Naruto, Hunter x Hunter, Marvel, Bleach, and Fate, but he wrapped up in Marvel. In a post on Qidian, he mentioned that personal circumstances, like a busy lifestyle, and the book's reception played a role in the decision to stop at Marvel.
