Chapter 47: River Woe, River Woe!

Three days passed in the blink of an eye. Xu Guang began cultivating the Returning Mountain Skill. Having cultivated it once before, his progress was remarkably fast.

The only downside was the consumption rate of his Essence Blood, which far exceeded what it had been when he practiced Skin Polishing with the Golden Willow Skill. This made sense. It was like a wall—the further inside, the smaller the surface area and the less material required. But now, he needed to reinforce a wall that was already quite thick, which naturally demanded more materials.

Xu Guang didn't mind. He estimated that it would take dozens of drops of Essence Blood at most to elevate the Returning Mountain Skill's Skin Polishing to the Realm of Great Perfection. He wondered how much his strength would increase by then.

After eating, Xu Guang left the Inner City and headed to the Immortal Institute. He entered the gates at almost the exact same time as Xu Sanduo.
