This was the first time, ever since Chen Changsheng and the Black Dragon had gotten to know each other, that the Black Dragon had agreed to help without first negotiating some benefit. This was because that demon had stirred some rather unhappy memories. That giant iron pot made her feel especially annoyed, and when that demon woman brought up that man who had eaten dragons, it made her even more annoyed.
The Black Dragon left Chen Changsheng's hand, turning into a shadow that was invisible to the naked eye. It surged towards the center of the lake, then noiselessly dived down like a falling leaf. It easily followed that tunnel which reversed the sky and earth and returned to the chilly pool by the cliff. Bursting through the water, it flew towards the gardens.
