But those incidents became increasingly rare and Qin Feng was probably the first person in the Qin family over the past 10,000 years to have developed chaotic mental demons.
In present times, chaotic mental demons were like a nightmare that one could never wake up from. Once it developed, no matter how powerful the practitioner was, he would be ruined.
But 300 years into the future, this was no longer a difficult problem.

Qin Feng turned toward Ye Qing. He had no idea what chaotic mental demons were. But he didn't harbor any high hopes for this teacher. He was just fulfilling his promise and passing the time.
"I will set aside an area outside the classroom for you," Ye Qing said.
By the side, Nangong Lie and Lei Yan pricked up their ears.
Wah!
