Qingfeng Li learned from Sky-fighting Immortal General that the Thunder Immortal's enemy was the mighty Chaos Demonic god from the Chaotic Era of the Universe.
Hoo!
Qingfeng Li took a deep breath. He kept wondering who could kill the powerful Thunder Immortal. Other self-cultivators and immortals weren't the Thunder Immortal's match at all except for the Chaos Demonic god.
After all, the Thunder Immortal was the master of thunder with natural power.
The Sky-fighting Immortal General saw his hesitation, saying, "Little guy, I know the power of the Chaos Demonic god. Even the Immortal Monarch may not be able to defeat him. I don't blame you if you don't accept this request."
"You don't have to kill the Thunder Immortal's enemy if you give up his inheritance. But you must do it if you take the third part of Thunder Immortal Sword."
Qingfeng Li frowned a bit and started to weigh up the pros and cons.
