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 its successor, 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. The only one still by his side was his childhood sweetheart, who refused to leave him.

Those who love me will receive tenfold in return. Those who harm me will pay a hundredfold!

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