Wings of Silence: Dark Knight Returns

Life in Lanling was tough for Jin Rulan, and some doubted his eligibility for sect heirdom. All because of his dysarthria.
Bullying... criticising... humiliating... from children and adults alike, drove him to the point he finally decided to act mute.
Alas, years of keeping silent may have made his body forget how to talk...
Until a tall Jiang senior saved him from a fight and turned his whole life around.

With everyone whispering Jiang Yanli was growing weaker... and that it's her fault her son was mute... and a strange plague called the Silent Death spreading... and Jin Ling being a suspected culprit... the era was only turning into more and more of a mess...

"Looks like it's time for Heiguang-Jun to come back," Wei Wuxian sighed as he watched the terror unfold.
Lan Wangji silently crossed his hands behind his back, nodding slowly. "Mn. It's been a while."

The story's a sequel of "Dark Knight", you might want to read that first. The plotline isn't affected much by the first, although it would help you to check out the first beforehand.
