You Take My Command and Break Our Engagement? I'll Fuse with Li Cunxiao and Rebel

Xiao Jingyu guarded the borders of the Great Qian Dynasty for three years. Instead of a reward, he received an edict stripping him of his rank and reducing him to a commoner! The court officials called him a brute, the great clans treated him like dirt, and even his fiancée publicly broke off their engagement. Fine! I quit this rotten job! Then he activates the Eternal Chinese Heroes Selection System and merges with 30% of Li Cunxiao's template from the start! You think I lack connections? Kings are no match for Ba Wang, and generals are no match for Li! My fists are the biggest connections I need! The great clans want to crush me with their rules? I'll smash those rules with one punch! The court officials want me dead? I'll send your whole clans to the underworld first! When Xiao Jingyu rides alone back to the capital, every powerful courtier is left speechless with fear! “Grandpa Xiao, please, have mercy and stop showing off your divine powers!” Xiao Jingyu sneers. “Now you want to beg for mercy? Too late!”
