Longevity Martial Arts: Starting Out as a Master of Playing the Pig to Eat the Tiger

Updates stopped on July 2. Don't bother reading. I am Wei Qinglan, Crown Prince of the Li Kingdom! After being framed and stripped of my title as Crown Prince, I took on another identity and disguised myself as the young master of a minor clan to evade the search and assassination attempts. Once everything is cleared up, the empire and its throne will be mine for the taking! But I've realized that something is off not only with my wife, but even my usually proper younger brother is starting to act strangely. Through a series of twists and misunderstandings, the three of us become entangled. One secretly builds up a faction to make a comeback, one quietly trains demonic servants, and the other struggles to clear his elder brother's name. As time goes by, things only get worse...
