In 2077, a mysterious virus called "Ember" suddenly broke out and swept the world with lightning speed. Not only can it quickly destroy the human immune system, but even more bizarrely, it can cause unknown reconstruction of the infected person's genes. Cities are reduced to ruins, order is gone, and human society is on the verge of collapse. Chen Yuming managed to survive the early stages of the virus outbreak. He kept traveling through the ruins and witnessed the glory and darkness of human nature. Relying on the knowledge accumulated in the laboratory, he discovered that the "Ember" virus did not seem to be naturally generated, and there were unknown secrets hidden in its code. In order to find the source of the virus and a possible antidote, Chen Enriming embarked on a dangerous journey. Not only did he have to avoid the threats of the violent infected and other survivor groups, he also had to race against time to decipher the "embers code" hidden under the destruction before the virus completely changed the fate of mankind.
