Divination

The next day, Ning pulled out Black Halo's talisman and read it out loud.

"Goes to a town… healer… gives him books… goes to another town… tries delicacies… stays in a tavern for the night… leaves for a major city. Hmm, everything is here. Not bad, you really can divine quite accurately," Ning said to Black Halo.

"Thank you for your praise, sage," Black Halo said.

"Now that I know you're good, I need your help," Ning said.

"Anything," Black Halo said.

"Good, let's go then," Ning said and grabbed Black Halo before disappearing from where they were. When they reappeared, they were inside the secret realm.

Black Halo looked at his changed surrounding with a wide eye. He couldn't help but be shocked at what had just happened.

"How did we…?" he looked around, very much sure that they were not in the same space anymore. 

Ning had teleported somehow, and he hadn't used any skill, law, talisman, or formation to do so.
