"The Mind-Only Gate" was a special item. Although it could only be used once a day, it had become a gateway connecting different spaces. He had used it before in Bai Kou's Spiritual World and successfully reached another layer of space within her mind. He wasn't sure whether it would help, but for the moment, he had no better options.
