Dragon Backbone: Chinese Mecha Hunting Record

In 2149, the alien colonial power Oort Alliance launched the "Razor" War. Orbital bombing severely damaged China's industry. Humanity retreated to underground cities and lunar bases, and the earth fell into an existential crisis. Gu Changcheng, a low-level mecha maintenance worker, was fired from the company for privately modifying military bionic bodies. He took the Android No. 7, Which he had put together for three years, and hid it in the underground maintenance station of Hong Kong City. The debugging code of "You are like my family" three years ago awakened No. 7'S self-awareness, suppressed the built-in killing module all year round, and silently guarded Gu Changcheng. The Ort Purifier troops raided the underground shelter. Former senior brother and capital agent Zhao Entropy led the encirclement and suppression, threatening the lives of the people in the city in an attempt to seize the No. 7 Prototype core unlocked by Gu Changcheng's emotional bioelectricity. In a desperate situation, Gu Changcheng activated No. 7'S guardian agreement, and his bionic body unlocked its full combat power. Federal tactical analyst Su Jin provided remote tactical support under the codename "Sky Eye" and became his confidant in the war. The "Great Wall" mecha, which was born based on Core 7, made Gu Changcheng the key executor of the top-secret "Dragon's Back Project". From the underground rusty iron labyrinth to the starry sea defense line, one person and one aircraft went to the moon and Mars to fight back in bloody battles. They finally understood that the so-called Chinese Dragon Backbone was never about strong armor and sharp cannons, but the burning original intention of being willing to face the cannon fire for the compatriots.
