How views are counted on Webnovel is a bit more complicated than it may seem. Any view that is shorter than a minute isn't counted. In most cases this would hardly make a difference, but with this book in particular, at least 80% of the views aren't being counted. So the 1.6 million views this book currently has would translate to well over 1.6 million minutes spent on this book.
The true view count would also be much higher.
