Two years ago, in the battle of the "Abyss Corridor" in the underground cave, the entire military genius team was wiped out, and only Lu Chen was captured.
The aliens planted an "abyss mark" on him and transformed him into a chess piece lurking in the human race.
Two years later, he "defected" and returned, handing over intelligence in exchange for trust, but he had to wear a monitoring bracelet and live in a cage of suspicion.
His left arm has alien lines, his pupils will turn into vertical pupils, and his memory is filled with the screams of his comrades.
His ability "Abyss Simulation" allows him to perfectly disguise himself as a foreigner, and even temporarily copy other people's martial arts - but every time he uses it, he is pushed into the abyss.
Inspector Lin Jing was ordered to monitor him, but gradually discovered the contradictions in him; hot-blooded junior Su Ye worshiped him, but did not know that he was the secret of peace between the two races; Abyss Princess Zero developed a twisted obsession with him and wanted to drag him completely into the darkness.
The real mastermind behind this is Qin Cang, the most dazzling hero of mankind.
When the boundaries between war and peace, loyalty and betrayal, humanity and bestiality are all blurred, Lu Chen must make a choice:
To be part of the abyss, or to be the light that illuminates the abyss?
