Invincibility Starts from Immortality

In the battlefield that encompasses all races, ferocious beasts roar across the sky and earth. Ancient ferocious birds spread their wings and shake the universe. Looking down at the small body beneath them, the undercurrents of all races are surging and fighting endlessly. God, the demons stand at the top of all races, and no one dares to compete with them. The human race has a gap in martial arts, and the weak warriors face the pressure of all races and have to be careful to rely on. After Bai Kai obtained the Immortal Mark, he vowed to lead the human race above all other races.
