Taxi driver Liu Yun is escorting an elderly scientist when they are ambushed by foreign spies. After his death, researchers upload his consciousness to a server called Guixu, turning him into a digital human and launching him on a fantastical adventure in a new world.
When Guixu comes under a furious attack by foreign hackers and teeters on the brink of collapse, Liu Yun gradually grows stronger. Alongside the Guixu project researchers and countless heroic spirits of martyrs whose consciousnesses have also been uploaded, he takes on the duty of protecting his country: stopping foreign hackers from stealing Guixu’s core code and safeguarding the countless lives within it.
