After some time had passed, Chen Changsheng estimated that it was early morning. He stood and indicated to the Black Dragon that tonight's lesson had to stop here.
The Black Dragon was clearly not too happy, but, in its great benevolence, did not stop him from leaving.
He raised his head to the ceiling of the cavern. From the ground, the bottom of the well was just a tiny black dot, with no morning light leaking through.
How could he get up there?
He recalled how he had left this cavern the first time and his expression seemed to slightly freeze. With all due haste, he took off all his clothes and put them away. He was mentally preparing himself for what was soon to come, so he failed to notice that as he was doing this, the Black Dragon was clearly showing disgust and anxiety in its eyes.
With a flash of light, Chen Changsheng's body vanished.
