Lu Qingya, a young man in green shirt, embarks on a journey to find twenty-eight star cores with an ebony sword that can sense the stars. From the shadow of a dragon in the East China Sea to the smoke of a wolf in the Western Region, the awakening of every star is accompanied by a shocking secret. When he discovered that the leader of the Qiyao Alliance was actually related to the death of his master, and when the twenty-eight guardians died one after another from the star core backlash, there was a cruel truth hidden behind the Xuanji formation set up by the ancient heavenly officials that could reverse the yin and yang. This is the road to salvation guided by the star map, and it is also the God-killing book written by the stars.
