The Venerable Xiang Yu, an eccentric villainous half-blood demon King was infamous in both the demon and human realm for being a cold-blooded ruthless devil that could kill with no remorse. 
Demons and humans feared him, cultivators wanted him as a trophy and the immortals saw him as a thorn in their side. 
The only reason he didn't get smote by the Heavenly King's searing lightning of divine wrath that could kill all mortals and immortals was because he kept the deadliest demons in check maintaining peace between the two realms. 
Despite his reputation, he had a small cult following in the human realm. They took him as their deity for his selfless acts of benevolence.
Such rare selfless acts led him to rescue the fallen immortal Han Xin. But his benevolence became his downfall. Condemned to death, he faced an impossible choice: serve the Heavenly King or die with no marked grave.
Xiang Yu: Hahaha... death isn't so bad after all. 

Heavenly King: You... 

Han Xin: Wife, you can't escape even in death. At least when you are alive you have a chance to run. 

Xiang Yu: QAQ...

Venerable Demon King & The Doting Immortal (QT)

Han Zhan's hand paused mid-stroke, the cloth stilling on the blade. He looked up, a chuckle escaping his lips. "Dage, if you're ugly, then what would that make me? Hideous?"

Han Xin's lips twitched into a faint smile, but it quickly faded. "Someone called me ugly the other day," he said, his tone more serious. "They called me an ugly bastard."

Han Zhan's brow arched. Who in all the realms would have the nerve to call Han Xin ugly? That could only be a lie. "You are neither ugly nor a bastard. They probably just wanted to get under your skin. Humans do that sometimes," he replied but Han Xin glanced at him before asking,

"And what if they had the truth-seeking whip wrapped around them?"
