Have You Ever Heard of a Mystical Immortal Technique?

...

When those words were said, everyone's faces could not help but turn red.

"Cough, cough... Actually, we were attacked by an immortal sect that specializes in lightning immortal techniques."

"An immortal sect that specializes in lightning immortal techniques? Then the other party is incredible! In the entire immortal world, although there aren't many sects that practice lightning-type immortal techniques, each and every one of them is an extremely difficult existence to deal with.

"Their overall ranking isn't high in the immortal world, but their lethality can not be underestimated.

"Did you guys see what they looked like?"

The Grand Elders immediately shook their heads in unison.

"When we met them back then, they were all wearing black clothes and masks, so we couldn't recognize their identities at all."
