Thunder Origin!
This is the inheritance left by the Thunder Emperor in Jing Yan's Chaos World within the Purple Thunder Forbidden Zone. Back when Jing Yan entered the Immortal Domain, he went to the Purple Thunder Forbidden Zone to undergo trials and simultaneously received the Thunder Origin inheritance.
However, because this inheritance is extremely mysterious, at Jing Yan's realm and cultivation level at that time, he simply couldn't bear the full content of the Thunder Origin. Therefore, this inheritance always existed in a compressed form within Jing Yan's Divine Soul.
When Jing Yan stepped into the All Things Realm and Nether Sky Realm, he tried to unlock Thunder Origin, but he didn't succeed. At the moment Jing Yan entered the Immortal Rhythm Netherworld Realm level in the Yellow Spring Cave, while checking his Divine Soul's memory, the Thunder Origin abruptly unlocked.
Suppressing the excitement in his heart, Jing Yan reviewed the Thunder Origin, this Immortal Technique.
