Zhang Long

History
The stronger of two Golden-Class Martial Artist assigned to Li Cihua by Cihua's hidden boss.

Personality/Appearance
Described as a 'skinny man with looks so common he becomes virtually invisible in crowd,' he is shown to be a little arrogant, doubting Lin Yi's abilities, and thinking he wasnt needed for the job, that his partner Li Yao would have been enough alone, leading him to reckless anger and thus the bad decision-making that ultimately caused his death. He hates following people who are physically weaker than him, like Li Cihua, but will follow orders regardless.

Book 1: A Curious Assignment
The Solid Cloud Arc, Chapters 160-167:
 * He first met Lin Yi after his boss, Li Cihua, called Lin Yi into his office so they could meet personally and discuss the possibility of Lin Yi switching to their side.
 * Upon Lin Yi's refusal, he and Li Yao were ordered by Li Chua to tail and kill Lin Yi. Unfortunately for them, Lin Yi was skilled enough to tell he was being tailed, and led them to a cliff-side trap. He parked his car and stood in the middle of the road, giving them the opportunity to run him over with their car. But at the very last minute he used his super speed and hidden boot knife to quickly dodge to the side, while at the same time puncturing one of their front tires with a kick. This caused the tire to explode and turn the car sharply, breaking through the railing, and flying over the side of the cliff to a fiery explosion below, killing both of them.
