The Most Powerful Weapon of a Billionaire Son-In-Law

Han Hui, 23 years old. People in the world call him "Tyrannosaurus". The "most powerful weapon" ranked first in the world's underground black list, the ultimate representative of the mercenary king. Three months ago, during a cross-border mission, I learned that my only relative - my sister Han Xing - had suffered an accident due to the betrayal of her friend Ke Lan. When her sister passed away, her only last words were that she hoped her brother could fulfill his promise of repaying the eldest daughter of the Lin family on her behalf. Therefore, Han Hui chose to remain anonymous and returned to Jiangcheng to join the Lin family.
