Douluo: Rebirth of Ning Rongrong, Xiao Wu Sacrifices at the Beginning

In an accident, Zheng Jian was reincarnated in Douluo Continent and obtained the legendary system! He originally wanted to rely on the system to conquer the Douluo Goddess, but he didn't expect that this cheating system actually turned him into Ning Rongrong, the eldest lady of the Qibao Glazed Sect.
