A Good-for-Nothing from the Start? I'm a Legendary Ancestor!

In my previous life, I was the greatest cultivator in the realm of cultivation. After being reborn, I became a good-for-nothing despised by everyone in my clan. The day I was cast out, my cousin sneered as he crushed my jade pendant beneath his foot. “Good-for-nothings deserve what they get.” I lowered my eyes and said nothing, while the vast memories lying dormant within me quietly awoke. That night, I casually improved the clan’s treasured Basic Body Tempering Art. At the auction house, the manager trembled as he held the improved technique. “This is priceless!” My cousin was sent to seize it, but I knocked every last tooth from his mouth with a single move. He shrieked in terror, “You’re just a good-for-nothing at the Qi Refining stage!” I smiled faintly. “Using the trash techniques you people look down on is more than enough to beat you.” In a corner, the nemesis who had hunted me in my previous life stared at a crystal ball and murmured, “Rating: SSS+... He really has returned.”
