A Useless Start? My Great Ancestor!

I was the number one person in the world of cultivation in my previous life, but after my rebirth I became a loser that everyone in my family despised. On the day I was expelled from the family, my elder brother laughed cruelly and trampled my jade pendant to pieces: "Trash should be treated like trash." I lowered my eyes and said nothing, but the vast memories that had been dormant in my body quietly awakened. That night, I casually improved the "Basic Body Refining Technique" that my family treasures. In the auction house, the steward held the improved technique and trembled: "This is a priceless treasure!" The clan brother was ordered to snatch it, but I knocked out all his teeth with one move. He screamed in horror: "You're just a waste in the Qi refining stage!" I chuckled: "Hitting you with what you think is rubbish is enough." In the corner, the old enemy who chased me in my previous life stared at the crystal ball and whispered: "Score SSS+... He is indeed back." ---
