My Returned Uncle Is a Catastrophe-Class Mage

Baek Kangjin, a returnee from another world and a former microbiology researcher.

After slaying dragons with the Mad Dragon Disease virus and surpassing the limits of humanity through neural network modifications, he finally returns to Earth.

A ruthless mage who manipulates microorganisms and viruses.

To his enemies, he is a merciless walking catastrophe. To his nephew, he is a warm-hearted uncle who offers an ordinary, peaceful life—all while leading a double life.
