On the abandoned planet X-937 where the rust-colored storm never ceases, former special agent Cheng Jin spent ten years in exile dismantling the remains of mechas. A conspiracy has already defined him as an abandoned son, and buried him together with his memory and glory.
Until a faint blue light curtain called "Return to the Ruins" forcibly invaded his life, using the nano bombs in his body as a threat, and launched an impossible mission. Cheng Jin, who was forced to return to the dangerous star sea, made a shocking discovery in the process of seizing the key black box: the failure ten years ago, the disappearance of his mentor, the mechanized transformation of his best friend, and even his own "existence" were all the product of a shocking conspiracy that spanned the "Tianshu Council" and the "Mechanical Holy See" - "Project Echo".
He is a clone, a backup of consciousness, and a key container for awakening the ancient "ancient gods" and ruling the galaxy. Holding the Guixu System left by his mentor with his life, Cheng Jin must tear through the lies and regain the truth of his memory when faced with his former lover Arya, who has become a Saint of the Mechanical Vatican, and "Copy No. 1" Who is exactly the same as him but more powerful and ruthless.
This is an interstellar escape and resistance between steel and flesh, memory and lies, freedom and control. When the fate of the galaxy hangs in the hands of a "fake", Cheng Jin will fight for his true self until the end.
