A meteorite hit the orbiting space experimental station, and the experimental station crashed into the city's airport. Various viruses and bacteria in the experimental station were leaked due to the rupture of the container. Viruses and bacteria spread at an incredible speed and method, causing widespread infections of humans and animals around the world. Most of the world has become the territory of the infected, and uninfected humans are imprisoned in different areas of limited area on each continent. After hard work, mankind finally developed a vaccine at an unbearable cost. The super factory that produces vaccines has stopped production for unknown reasons. It was later found out that the core chip of the Gigafactory failed, causing production to stop. The control room of the Gigafactory was on the top floor of a hundred-story super-powerful building. The condition of the building is unclear, and no one responded after multiple calls. It is inferred that all the people in the building have been infected. In order to eliminate the fault and replace the chip with a new one, Xia State, which is closest to the Gigafactory, sent people to investigate. In order not to disturb the infected biochemicals, the smartest and most powerful all-round warriors must be dispatched. Zong Yan, Gan Tian, and Liu Changle are the top warriors of the Xia Kingdom's army, air force, and navy. They are about to embark on a bloody journey to save mankind.
