A day and a half later.
A carriage entered through Nuoding City's north gate.
Inside sat two people, one older and one younger, both equally dark-skinned and ordinary-looking.
They were none other than master and disciple, Yu Xiaogang and Tang San.
Yu Xiaogang had been injured on the back, especially his buttocks, where the flesh had been torn open most severely.
Only a few days had passed, so the wounds had not healed so quickly.
At that moment, he could only lie face-down on the carriage's crude couch.
As the carriage jolted along, he occasionally bared his teeth and sucked in sharp breaths.
Yu Xiaogang's injuries looked serious, but they had not damaged his muscles or bones. They were merely flesh wounds.
He was simply somewhat weak from excessive blood loss.
If he wanted his wounds to heal quickly, he only needed to return to Nuoding Academy and find one of the academy's Healing Type Teachers for treatment.

Even more astonishingly, his Mysterious Heaven Skill Internal Energy had perfectly fused with the power of the Spirit Ring.
The fused power was no longer merely Internal Energy,
