The so-called independent private room was just a cubicle less than four square meters. It was only the size of a latrine, but the cost of 15 minutes was 600 taels of silver. It was really worth every second.
Of course, this independent private room was mainly expensive because of the soundproof array foundation.
After entering the room, Han Zhao tried to extend his mental power out of his body. Just as his mental power touched the wooden wall of the cubicle, he felt a resistance.
"Other than soundproofing, an array foundation that can even isolate mental power perception is really magical."
Han Zhao thought to himself. If he forcefully broke through, he could break through the barrier of the array foundation, but it would definitely attract attention.
