Drinking tons of vinegar
As the sun dipped low on the horizon, casting a warm golden hue across the vast expanse of shimmering fields in the outside world, Xiang Yu was lying down cross-legged in his spiritual space waiting for the old man to show his face. While waiting, he had changed things around, making the space an exact replica of his courtyard in his palace.
He repeatedly called out to the Divine Emperor but the old man wouldn't answer. He even tried to call him Old Man, Old Coot, Immortal Geezer and lord of the Bald Donkeys, but no matter how many names he used, the old man wouldn't answer. It was either he was blocked or their line got disconnected somehow.
Since the old man was playing hide and seek, he decided to find something to entertain himself. As a pastime, he was watching an exciting show that he happened to stumble upon. This show so happened to be what they classified as a boy love genre with a vampire doctor working at an underground boxing ring.
