Everyone who comes to the Sacred Abyss Continent obtains a Demon Slayer Token from the Great Thousand Palace. Every time they kill a member of the Fiend Clan, they will be rewarded with Demon Slayer Points accordingly, which can be exchanged for treasures in the Great Thousand Palace. Killing a member of the Fiend Clans with the cultivation of a Lesser Earth Sovereign will award you 50 Demon Slayer Points. 100 for a Greater Earth Sovereign, and 200 for a Perfect Earth Sovereign. A Monarch with strength of a Spirit Heavenly Sovereign worth 3000 Demon Slayer Points, a Monarch with strength of an Immortal Heavenly Sovereign is worth 5000 Demon Slayer Points, and a Sky Monarch awards you 10,000 Demon Slayer Points. To become the Demon Slayer King, one must have 10,000 Demon Slayer Points or kill a Sky Monarch.
Qin Tian was the first Demon Slayer King after killing a Sky Monarch, and Mu Chen[1] was the second after he helped the Pagoda Ancestor to kill the Blood Vampire Sky Monarch.
