Back to 1965: the Great Detective's Road to Protecting the Country

1965 Was a year of burning passion and a turbulent undercurrent. Gu Yan, a top criminal investigation expert, was unexpectedly reborn and returned to an era when precision industry had just begun and enemy organizations were dormant. At this time, he was just an ordinary policeman in the capital, but the "Great Power Detective System" had awakened in his mind. [Micro Vision]: Any tiny hair, fingerprint or even metal molecule-level errors cannot escape his eyes. [System Mall]: As long as you complete tasks and accumulate points, you can redeem them for era-changing industrial blueprints: magnetic levitation centrifuges, high-performance special steels, supercomputing logic architecture... Starting from a "negative tolerance gasket" that destroyed production, Gu Yan used his body to tear open the dragnet laid by the mysterious organization "701". In the Friendship Store, he slapped the faces of arrogant foreign experts with his pure London accent and uncanny watch repair skills; in the Western Suburbs Hotel, he transformed into "Tony Gu", a wealthy young man who returned from the country, talked and laughed with top spies, and deciphered the "Silent Spring" poisoning plan. However, as the investigation deepened, a top-secret file that had been sealed for fourteen years surfaced. It turned out that his father Gu Changfeng, who was believed to have died, had not left, but was imprisoned in the "Ultra North Forbidden Zone" deep in the Greater Khingan Mountains, guarding the ultimate secret about human evolution. For the sake of the righteousness of his family and country, and to find out the truth about his father, Gu Yan went north to the cold land and stepped into the gate of the abyss. He will use the microscopic eyes in his hands to carve out a technological light leading to the pinnacle of the Republic under the ice of the earth!
