"Soundproofing Technique?" Ma Zhihao was surprised.
Tang Huai smiled, "Does your home have a telephone? It's somewhat similar to that."
Ma Zhihao's home had a telephone, so he seemed to understand quite a bit with Tang Huai's explanation.
He reached out to Tang Huai, "I also want the Soundproofing Technique. Give it to me, it would make it easier to contact you."
The Soundproofing Technique resounded directly in the mind, with no need to dial, and was convenient to carry.
Tang Huai laughed, "I can't give you the Soundproofing Technique. It's not a physical object."
Hearing this, Ma Zhihao got curious, "Not a physical object? Then what is it? Could it be... a spell?"
Tang Huai turned her head, looked at Ma Zhihao for two seconds, then shook her head, "No, it's a special ability."
"Special ability?" Ma Zhihao didn't understand special abilities.
"It requires cultivation."
"How do you cultivate?" Ma Zhihao was thoroughly confused.
