Even Huan Caiyi got stunned.
All secret skills used to hide cultivation levels work by blocking the natural spirit qi emission from the body.
But there are no skills available in this world which can completely block the spirit emission to the level of mortals, at least she hadn't heard of them.
She couldn't help but ask.
"What's the grade of the skill?"
Instead of answering, Jiang Hao took out the cultivation technique and handed it over to Huan Caiyi.
She took the technique and read out loud.
"Heavenly Lotus Sutra"
She was surprised but wasn't shocked as she had already assumed that a skill of that level could only be provided by a heaven-grade cultivation technique.
