Chen Jin traces the clues that lead to the demise of the team, pointing to the empire's top secret laboratory "Ark". The research results of Jiang Li's parents are the core of the "Ark" project, and he is also trying to infiltrate the "Ark". An assassination operation against a senior official of the empire (led by Shen Jin) and a bizarre laboratory pheromone leakage accident (planned by Jiang Li) unexpectedly intersected. The two met for the first time. The pheromone/spiritual power resonated fiercely and abnormally, arousing strong interest (and vigilance) in each other. They were forced into the same larger conspiracy vortex, surrounding the ultimate secret of the "Ark" project - a dangerous source of energy "Eclipse" that can rewrite the rules of ABO and grant or take away superpowers.
