Gu Anxi accidentally traveled to Douluo Continent and awakened the strongest sign-in system. Not only did he obtain the strongest weapon in the universe - the Star Sword as a martial spirit, but the soul rings were all white hundred-million-year-old soul rings. However, Gu Anxi's system was a bit cowardly, and he had to make Gu Anxi completely invincible before letting Gu Anxi come out.
