Chapter 4060: Darkness

"Husband, have you completely mastered the first level of the Purple Blood Secret Manual?" Leng Rushuang asked.

"How could it be so easy?" Jian Wushuang shook his head and smiled.

The first level of the first three levels of the first volume of the Purple Blood Secret Manual required him to completely comprehend the first 12 pieces of crystal jade. In the past 30,000 years, Jian Wushuang had already comprehended the first 10 pieces of crystal jade.

He was very close to completely comprehending the 11th piece of crystal jade, but he was still far from comprehending the 12th piece of crystal jade.
