Black Great Sage: Mecha Immortal Legend

In the late 21st century, the international mecha arena saw China crushed. Engineer Lin Mo defied orders to pilot his self-developed 'Great Sage' mecha, achieving legendary status and winning back national dignity. However, instead of rewards, he received a termination letter—five years of hard work erased, his achievements stolen by his boss's son, and he was left with only 500 yuan severance before being blacklisted across the industry. Stranded in the lower city, Lin Mo accidentally activated his father's legacy, the first-generation 'Pangu Core', and assembled a black mecha named 'Black Great Sage'. When the Four Heavenly Kings attacked, he defeated them all with a single strike.
