City of Origin of Heroes

In the year 2022 of the Qing calendar (5302 of the Earth calendar), Zhang Qifeng, a historical archaeologist of the Qing Dynasty, found a diary in the Origin City of Zhongxin Lake. From this diary, he obtained the history and secrets of the Origin City. At the same time, Miss Wang Xueying of the Wang family also gained experience in the Origin City. The Wang family and the Zhang family are feuding. The Wang family was originally one of the four major families, but was replaced by the Zhang family three hundred years ago. Since then, the family has declined and the two families have become a feud. Now that the two families met in a dangerous place like Origin City, a fierce battle naturally broke out. The Zhang family lost to the Wang family, and Zhang Qifeng was forced to disclose a place marked in his diary that said there was a secret treasure. After that, he took everyone from the Wang family to hunt for treasure, but accidentally triggered a mechanism while hunting for treasure. Both he and Wang Xueying fell into the depths of the Origin underground and lost consciousness. A week later, the two were found unconscious in the ruins of Origin City by their respective tribesmen. However, both of them had forgotten the memories of this week. A year later, there were rumors that Wang Xueying ran away from home and kidnapped Zhang Qifeng, a direct descendant of the Zhang family. There were even rumors that the two fell in love at first sight in Origin City and eloped. But no one knows what the real situation is. Sixteen years later, a young hero appeared in East Han City. He walked through the Hero's Road alone. He had great skills but worked anonymously as a guard for the Wang family. What was his purpose?
