Introduction to Chang'an Rain Tribulation
At the end of the 21st century, Xi'an encountered unusually sustained heavy rains. During the rescue, emergency doctor Lin Lan discovered that the patient was extremely thirsty for water and had scaly changes in his skin. Unknown microorganisms in the rain were modifying human genes, and some people became aquatic beings who could breathe underwater but lost their humanity.
The urban drainage system collapsed, the government blocked urban areas, and social order collapsed. Lin Lan rescues the mysterious man Gu Bei, who seems to know the secret of the rain disaster. The two went deep into the underwater city to find a way to stop the rain, and discovered that the source of the rain came from an ancient biological engine deep in the Qinling Mountains - this is the earth's immune response to human destruction.
When Lin Lan had to choose between saving humanity and allowing the ecosystem to heal itself, the heavy rain suddenly turned into a blizzard, freezing Chang'an, and the survivors faced a new life and death test.
