Not Teleportation

The creature looked humanoid. Because it was wrapped up in black armor, it was impossible to tell exactly what it looked like. It just stood behind the Demon King.

"Sir, I have brought you the Demon Doll." The Demon King brought the Demon Doll before Ji Yang Sheng, then raised both hands, presenting a purple horn.

The purple horn was around one foot long, and its surface was ribbed like a screw. It was crescent-shaped, and many strange symbols were carved around its top. It looked so pretty, but also so mysterious.

The horn looked like the horns on the heads of Demons like Ji Yang Sheng. Ji Yang Sheng didn't know what it was.

Ji Yang Sheng took the purple horn and turned it over in his hands. Then, he spoke to the Demon Doll. "Listen to my commands and go."
