That disciple looked to be in his early twenties. He had rather sharp features and was slightly more well built than normal disciples. But at that instant, he knelt at his stall with a melancholic expression. His large build was curled into a ball as he looked into the passing crowd sadly and helplessly.
Ye Qingtang looked at the stall in front of that man, and her lips slightly tugged up after this look.
The disciple was not selling any rare items but had some Spirit Crystals of varied sizes.
Spirit Crystal was a type of crystal which naturally stored spirit energy. Many veins occasionally produced it, and although not much was produced, it was not considered rare either. A Spirit Crystal was different from a Spirit Stone. The spirit energy in Spirit Stones could be absorbed and converted by humans while the spirit energy in Spirit Crystals was completely combined with the crystal, and there was no way one could extract it for cultivation.
