Jiuzhou Weibin: the Demon Lord Arrives

The best swordsman in Kyushu failed to overcome the tribulation and became a useless member of the sect. He had his bones stripped off, his engagement was annulled, and he was punished to raise pigs. At the end of the three-year period, he found himself in a desperate situation on the Zhuxian Platform, but he waited for his father, the demon king, who ruled all realms and slaughtered all the people for him. On that day, the whole of Kyushu heard a sentence - "Whoever hurts my son, the nine tribes will be wiped out." The top powerhouse traveled through time and became a useless man, dormant for three years. Finally, when everyone was betraying his relatives and leaving, he was recognized by the father of the strongest demon king in Kyushu in a high-profile manner, and staged the story of the return of the king.
