Background / History

The Immortal Slaying Sword was granted to Chen Ping'an by the Shared Cultivation System after he shared a fraction of the Primeval Lord of Heaven's cultivation. It was designated his First Martial Soul alongside the Immortal Execution, Immortal Trapping, and Immortal Annihilation Swords. 1

Initially recorded with nine red Soul Rings, it rapidly became Chen Ping'an's principal weapon against Titled Douluo, Soul Beasts, gods, and the Dark Demon Race. Its Soul Ring configuration rose from 300,000-Year rings to Million-Year rings as Chen Ping'an continued receiving cultivation-sharing rewards. 3 72 76
