Return to Battlefield

The Dragon Emperor remained stunned in the air some distance away from the teleportation formation as the light faded and Alex disappeared.

He witnessed the scene with some feelings of anger, horror, and confusion. 

Anger at the fact that he had even let something like this happen. Horror at the thought of what the result was going to be. And an overall confusion on why Alex had been able to activate a formation despite the lack of a key.

He had heard clearly what Alex had said at the end there. He had said that he needed no key. How was that possible?

Those were but fleeting thoughts for the Dragon Emperor, however, as another concern overtook his mind very soon.

What was he going to do next?

Alex surely hadn't left the battlefield, running away somewhere to save himself. He planned on coming back. It was what he planned on coming back with that concerned the Emperor.

Before that could even happen, he had to stop it.
