“Hmph, my dumb big sister is in danger!” A mischievous grin spread across his face. “Hehehehe... this gives me the perfect excuse to finally use this treasure I’ve acquired but never bothered with!” He rummaged through his belongings, carefully selecting various items. “A bit of this... and this... and a dash of this.” Boom! The explosion of energy sent a ripple through the air as he laughed maniacally. “Hahaha! It’s done! Now, all I need is a compatible host for it.” Years later... “Did I overdo it?” he wondered in awe, watching as his creation wreaked havoc, conquering world after world with ease, as though stealing candies from children.

Young Master He had always been a male god in the eyes of others.

Until one day, the god-like him died.

And he became the much detested white silk trouser-wearing second rich generation.

Male God He was unaffected by this.

In his previous life, he had sacrificed everything for his clan, now, he could finally break free from that tiring life.

The only thing was that he had gained a handicapped partner.
