You Just Build a Foundation and Let Me, the Great Emperor, Destroy His Cultivation at the Peak of His Power?

People are in fantasy, the emperor has been there for thousands of years, but the counterattack system just came? Looking at the crazy batch system, Qin Xuanfeng fell silent. "System, do you want to explain to me clearly what a big family headed by the foundation-building ancestor is?" "Building a foundation, can he also be called an ancestor?" Facing the weird system task, Qin Xuanfeng couldn't refuse, otherwise he would be wiped out! Ever since, seeing the emperor coming out of the mountain to hunt down a low-level foundation-building family, the style of the entire Daluo Dao Domain began to change!
