The death of the Sequence.
The tense atmosphere of the battle enveloped every corner of the earth, especially those bases and cities guarded by superpowers. Uzona's army not only relied on its powerful scientific and technological power, but also cleverly put poison in the earth's water source in an attempt to defeat the earth's defense from the inside.
The pollution of the water source first affected ordinary people, whose physical fitness was far inferior to that of superpowers and was quickly eroded by the poison. Many people began to suffer from serious symptoms, and the situation took a sharp turn for the worse. Hospitals and medical stations were overcrowded, and superpowers such as Li Xuan were unable to do anything. They had to resist the enemy's attack while taking care of ordinary people who were injured and sick.
