Ning had 4 fist-sized rocks in his hands that he was constantly juggling as well as he could. He himself wasn't very good at juggling, but he had a little help from elsewhere.
The rocks jumped around in his hands unnaturally because they were being manipulated using Aether. He was training his Aether usage before going to sleep so that he could get better at it.
While he still didn't have the talent for it, the practice was helping him get there.
The 4 rocks stopped juggling and dropped onto his hands. That was enough training for today. He threw away the rocks and went to bed.
He slept for as long as he could, but when he woke up, it was still very dark outside. 'Damn this planet and its long nights,' he thought. He would rather go stay at the south where it was perpetually bright, compared to this place where days were so long.
