As everyone knows, reviewers mostly work voluntarily. Especially for those bigwig-level figures, if the manuscript doesn't interest them, they generally won't accept it.
Sometimes, due to various circumstances, they take on a review task but don't have much time to read through the manuscript. Usually, they let their students look it over, or they glance at it during their fragmented time and finally provide an opinion.
Of course, there are articles that can make these bigwigs read deeply, but they are definitely not many—perhaps just a few each year. And most of them are the latest results from colleagues of the same level.
An article that, after a thorough reading, shows no obvious logical flaws and is set for a finer review represents a supreme honor for the paper's author.
This is enough to demonstrate the reviewer's cautious attitude towards this paper.
Of course, Qiao Yu was unaware of all this.
