In the future world, humans rely on "symbiotic bacteria" to maintain health, and Chen Jun is the developer of bacterial agents. One day, she discovered that the experimental bacteria suddenly mutated, and the infected people lost their emotions, and strange patterns appeared on the bacteria bottles - which were exactly the same as the patterns in the notes left by her father before he disappeared.
Chen Jun secretly investigates and discovers that the "original symbiotic bacteria" his father studied can give people super powers, but can cause them to lose control. She found her father's secret laboratory and found a recording in the petri dish: "The mutated bacteria are looking for the 'bacteria master', and only your blood can suppress it." At this time, the laboratory suddenly lost power, and the mutated bacteria spread along the pipes. The same lines as the bacteria bottles appeared on Chen Biao's arms, and she realized that she was the "bacteria master" her father called her.
