He was once the sharpest blade in the army, but the "failure" of a top-secret mission earned him a stigma and sent him to jail. Three years of purgatory, not only did not dull his sharp edge, but instead tempered him into a more terrifying "Yam Luo" appearance. After being released from prison, Shen Yi (codenamed "Ye Xiao") was ordered to break into the dark heart of Hai City - the Green Dragon Society - as a "released boss".
On his left hand is the bloody storm of the world. He stepped on numerous bones to climb to the top and became the feared "Brother Yi". He was ruthless and resourceful, and his powerful enemies were wiped out while talking and laughing. The right hand is a mission without light. He is a poisonous thorn that the country penetrates into the deepest part of the darkness. It dances on the tip of the knife and listens to the thunder in the silent place, just to uproot the rotten flesh.
Surrounded by ten beauties, each has his or her own merits: the cold and beautiful policewoman is his only contact who knows his identity, and she is also the white moonlight in his heart; the underworld lady is conquered by him but always wants to bite her back; the genius forensic doctor erases all traces of him; the wealthy daughter is his most solid treasury; the sassy female bodyguard protects her with her life; The mysterious hacker builds an information barrier; the tough female reporter is his sword to control public opinion; the gentle doctor soothes his scars; the Interpol loves and hates him; the amnesiac female killer becomes the sharpest knife in his hand... They are the jewels in his dark crown and the weakness that he cannot fall down.
When foreign gangsters reach out to the country's most important weapon, when former comrades draw guns against him because of his "blackening", when the president of the Blue Dragon Society hands over the "Dragon Ring" symbolizing supreme power... Shen Yi stands on the top of the abyss. In the name of "Yam Luo", he actually makes decisions! Only by being more evil than evil people can we slay evil spirits; by being more loyal than soldiers can we live up to the red flag in our hearts.
