บท 138: Natal Technique (2)

"From what I remember, the Spirit Restriction Seal was something that I comprehended on my own when I was still weak. It became my greatest weapon in the world of cultivation. This is a sealing technique that specifically targets spiritual energy. When I cast the spell earlier, I used the Spirit Restriction Seal to seal my breath and the spiritual energy that seeped out of the spell. When facing an enemy, their spiritual energy can be blocked and destroyed. According to my calculations, if this Spirit Restriction Seal is cultivated to the ninth level, even a true immortal can be killed!"

"Amazing! Shouldn't this be enough to kill any cultivator?" Jiang Ming could not help but ask. "Which level are you at?"

He was a little suspicious.
