A new life-form has appeared on Earth. Resembling a human infant, it was named the Bloodborn. Bloodborn mainly live in harsh environments, and their bodies harbor large quantities of viruses. After their discovery, people began to exploit their value. Bloodborn blood can suppress almost every harmful virus in the human body and cannot infect humans. Bloodborn also have powerful regenerative abilities, and their blood can be used to create various organs for humans and extend their lives. But Bloodborn are not carbon-based life-forms, and their numbers began to plummet. To ensure their survival, people induced widespread mutations. In the end, the blood began to infect humans. This virus is even more powerful than the zombie virus. It preserves human reason while amplifying people's desires. It is virtually impossible to kill, spreads through the air, and even reproduces in it. It is nearly immune to radiation, and Earth began to fall into ruin. Then a transmigrator, Wang Lin, logged into Earth.
