In the Scorching Apocalypse, the Koi Beast I Raised Transforms and Tears My In-Laws Apart

In my previous life, I listened to a Taoist priest's sales pitch and paid a fortune for a black-and-white koi. My in-laws scolded me as a money-wasting burden who could spend but not earn.

Unexpectedly, just before the high-temperature apocalypse arrived, my koi began to mutate into a beast. It spewed out gold coins nonstop, helping our whole family survive the crisis.

Once it had fully transformed, the koi could not only provide clean water, but also change the temperature around it. No matter how hot it got outside, our home stayed cool.
