Lord of the Sword Pavilion

There are many martial arts sects in the world, but there are only a few magic weapons... There is a saying that has been circulating for hundreds of years: "All the divine soldiers in the world enter the sword pavilion, and they all leave the sword pavilion." … People in the world who are not highly skilled in martial arts do not know where the sword pavilion is. They only know that every thirty years, four green-feathered eagles will hover in the sky, looking for the east, south, west, and north respectively. The young masters of the four pavilions return to the sword pavilion for a competition. The loser dies!
