Science fiction, suspense, mystery, wild imaginings, tangled timelines, and a biothreat!
He Ling San and He Ling Si are handsome twin brothers with very different personalities and interests. Together, they establish the Twin Spirits Detective Agency, specializing in unusual cases involving the paranormal, supernatural abilities, and difficult mysteries from among the people.
While investigating a supposed haunting at a gym, they discover that the ghost is no ghost at all. A beautiful woman has staged the haunting to draw out her sister's killer and avenge her. They soon learn that the suspicious security guard is being controlled by his younger brother, Xie Wuying. Xie Wuying is no ordinary person: born from a parasitic twin, he possesses extraordinary intelligence and a vicious nature. He uses an invisibility cloak for every crime, making evidence almost impossible to find.
To trace his past, the brothers use a time machine to travel back 24 years. There, they uncover his terrifying secret. Meanwhile, their senior schoolmate Jiang Linger passes through a light-wave portal and discovers the truth behind the explosion in a university laboratory 24 years ago, which claimed the lives of four scientists...
The virus sample she happens upon is stolen by Xie Wuying and becomes a biological weapon that threatens humanity...
But in the end, justice will prevail over evil.
