Su Jinyue opened her eyes and picked up the book on the cabinet. After spending time practising cultivation, she could see through things for more than a minute.
Looking at the clock on the wall, Su Jinyue took note of the time, before focusing all her attention on the book in her hand. The book cover slowly became transparent, and the contents of the book became clearly visible to her.
It wasn't until her eyes were sore that Su Jinyue withdrew her gaze and turned her head to look at the clock on the wall. A happy smile spread across her face. "It can already last for two minutes."
"Master has now reached the limits of the first level, Wisdom Eye. When Master breaks through to the second level, Master's X-ray vision will be able to last for five minutes. It's just that Master has to have a sufficient amount of spiritual energy, in order to break through to the second level."
