Vicious Fake Young Master, but a Pretty Idiot

Sheng Xuezhao was born bad. Since his earliest memories, he was already finding ways to get his parents to transfer all the family property to him. To become the sole heir of the Sheng family, he repeatedly made sinister moves against his elder brother, who was six years older than him.
Even after failing, he never gave up. Every year during ancestral worship and prayers to the gods, his only wish was to inherit all the Sheng family’s assets. Even with the Sheng family’s strict discipline, he still found every opportunity to bully others. He was jealous of the top student’s excellence and the poor student’s artistic talent; he used every means to humiliate them.
Later, it was revealed that he was not a child of the Sheng family, and the person he used to bully was the “True Young Master.” His parents, who had always doted on him, suddenly turned cold and wanted to kick him out of the house.
How could Sheng Xuezhao endure such a fall from grace? So, he turned around and drugged his older brother, climbed into his bed, and threatened his brother to marry him.
On the day the True Young Master returned home, Sheng Xuezhao walked downstairs clutching his brother’s arm, his face full of smugness. His furious father rushed over and raised his hand to slap him; Sheng Xuezhao stubbornly tilted his head up. The slap, however, landed on his older brother, knocking off Sheng Xing’s glasses.
“You beast!”
his father roared. Sheng Xuezhao:
“Eh???”
The Sheng family discovered long ago that Sheng Xuezhao was not their biological child. Sheng Xing knew it, too. On the eve of his biological brother’s return, Sheng Xuezhao—who had never given him a kind look—knocked on his door carrying a glass of milk, asking him to drink it with a soft, sweet voice.
Sheng Xing looked at Sheng Xuezhao, whose wicked intentions were written all over his face, and picked up the glass. The next day. A hoarse-voiced Sheng Xuezhao grabbed Sheng Xing’s hair and threatened him fiercely:
“If they didn’t get married, he would leak the video from last night.”
To prevent Sheng Xuezhao from leaking his video, Sheng Xing had no choice but to agree to marry him.
