Sun Wukong suddenly understood that only he, Leng Xuan, and Luo Bai could see the passage leading to the Ninth Layer. Perhaps it is related to them having sat on the heavenly throne?
Indeed, it must be so. When they sat on the heavenly throne, they likely acquired some special aura, or got marked with a special seal, allowing them to see the location of the passage, while people like Hong Jun Daoist Ancestor could not.
"Wukong, try and see if you can enter the passage to the Ninth Layer."
Hong Jun Daoist Ancestor suggested, and Sun Wukong nodded, exchanged glances with Luo Bai and Leng Xuan, and walked towards the passage to the Ninth Layer. To Hong Jun Daoist Ancestor and others, the three seemed to walk straight into the wall and pass right through.
"Ancestor, we can enter, come along!"
After the three figures disappeared, Sun Wukong emerged halfway through the wall, gesturing to Hong Jun Daoist Ancestor and others.
"It seems there really is a passage to the Ninth Layer!"
