I can kill everything with a single keyboard

A lightning strike transmigrated Zu An into another world. In that world, he was known as the trash of Brightmoon City, but for some reason, he was married to the gorgeous and highly talented daughter of the Chu clan?
What? I'm a transmigrator but I don't have any talent for cultivation? Why are there so many people out for my life? And most importantly of all, how in the world did I get on the bed of my sister-in-law on my wedding night?!
It was a nightmarish starting point for Zu An, but fortunately, as a famed keyboard warrior in his previous life, the world gave him a keyboard in this life too so that he could turn things around. Through his trolling and flaming, he shall stand atop the corpses of his burned enemies and rise to the top of the world!
