Crushing the Apocalypse, Starting with My Transformation into a Demon

[High Martial Arts + Play the Pig to Eat the Tiger + Ruthless and Decisive + Action-Packed Power Fantasy] After the world was rebuilt in the wake of darkness, some achieved sainthood with their bodies! Some amassed wealth enough to rival nations! And some wielded power that reached the heavens! But I, Zhang Daqiang, a hapless middle-aged man who transmigrated twelve years ago, risked injecting a bargain-basement gene-modification spiritual serum so I wouldn't hold my son back. Instead, I became a half-human, half-demon monster. I thought my time was up, but disaster turned out to be a blessing in disguise. Thanks to my half-human, half-demon body, I began to thrive.
