After Five Years in Seclusion, the Mad Doctor Returns

Five years ago, an accident nearly killed Yu Hualong. The Medicine King Island took him in as an heir, and countless powerful figures bowed at his feet.

Five years later, Yu Hualong returned to the city, only to discover that his entire family had been slaughtered. Only his childhood sweetheart stood by him, never abandoning him.

Those who love me, I will repay tenfold. Those who harm me, I will repay a hundredfold!

I repay kindness with kindness and vengeance with vengeance. I am invincible, so do as you please!
