A ghost could pass through objects, but she couldn't, so a tunnel must be dug.
After that, Gu Ning put the male ghost into the telepathic eye space again, because the monster fox will be released later. She needed to prevent them from encountering each other and causing trouble.
Although she could easily stop them from having conflict, it was better to avoid unnecessary trouble.
Once the male ghost was put back into her telepathic eye space, Gu Ning took out a hat and a mask from it and put them on.
She couldn't leave any traces when she came here to dig a hole. If she left traces, she would definitely be discovered. People might watch the surveillance videos to find her, so she had to cover her face to protect herself.
