Protection.

The boy sat down next to the leopard humming a gentle tune. Let alone the guards even the classmates have never known the boy to hum or sing. Tonight was the first time they have heard such a thing. 

Suddenly the Leopard raised her head and glanced in a direction in the mountains. Yang Dao asked, "Do you feel anything?"

He immediately spread out his perception but could not find anything. He said, "Sushi, wake up." At this moment he was wearing a fur coat. Sushi was resting in the fluffy collar. He spoke using the spiritual bond. 

It was similar to the bond he had with Feng Yun and the others. Yet this tiny sylph had taught him a spell and then the two people were capable of talking through thoughts. Sushi revealed her tiny head out of the fluffy collar and asked drowsily, "Master, what happened?"

The boy said, "Can you go in the direction this leopard is looking and report the situation?"
