Luo Xingchen, a 22-year-old mechanical repairman, grew up in the desolate ruins of the post-apocalyptic earth and made a living by dismantling old-era mecha parts. She accidentally saved a dying mechanic from the Caesar Empire, and was entrusted with an S-class mecha core chip by him before his death.
This chip contains the activation code for the Empire's most powerful combat mecha, "Shura". As for Shura, it was the exclusive vehicle of Helian Yuan, the Imperial God of War and Iron-Blooded Marshal.
Helian Yuan, 27 years old, is the youngest marshal of the empire and a semi-mechanical reformer. Cold, efficient, like a precision instrument. The "Iron Curtain Legion" he controlled was the empire's iron fist to suppress rebellion and maintain order. Rumor has it that he once personally detonated his left arm on the battlefield to kill an enemy leader, and then replaced it with a mechanical prosthesis without changing his expression.
What Luo Xingchen didn't know was that to activate Shura, the body temperature of a "bloodline resonance person" was needed. This means that as she holds the chip, she must keep close contact with Helian Yuan, otherwise the chip will self-destruct within a week.
In order to survive, Luo Xingchen faked his identity and sneaked into the central city of the empire, but in an accident, he met Helian Yuan on a narrow road. He discovered the chip in her body, but instead of killing her, he proposed a cold deal to her:
"Marry me for one year. After one year, the chip will be yours and you will be free."
An interstellar epic that begins with profit and ends with fate begins here.
