The Sword Sect Bullied Me for Being Old and Weak, So I Turned to the Great Path of Yin and Yang

After transmigrating, Zhang Qingcheng stuck to his boyhood cultivation, wasting his youth trying to establish his foundation. In the end, he accomplished nothing. Now in his twilight years, he thought his miserable life would come to an end at the sect. Then Ning Wanyu, his childhood sweetheart, who had entered the sect alongside him and was now its leader, came to him. She insisted that he leave the mountain before the next Swordsmanship Tournament and sever ties with the Tianhai Sword Sect. “Then I’ll leave?” Zhang Qingcheng gave a bitter smile. He thought he was out of options, but at the crucial moment, the System arrived! There’s nothing wrong with wanting pure love, but now that you have a System, you’re still going for pure love? Zhang Qingcheng planted his hands on his hips! Since the Sword Sect bullied me for being old and weak, I’ll turn around and devote myself to the Way of Yin and Yang!
