It's because it was Er Gen's novel. At the time of its release, it smashed several records. Being one of Wuxiaworld's most popular authors, Er Gen's name alone may generate a significant increase in readership. Not to mention the person translating this novel here, deathblade. Unfortunately, this work is not from Er Gen and cannot suffer the same fate. WW has previously stated that a work with a large enough translation would not be accepted for translation here, and I don't blame them at all.
But hey, if this gets taken up, I'll be very happy. Unfortunately, such an event may never occur.
