There was one point that Mo Yu hadn't pointed out. It wasn't that he sensed the chaos first before realising her importance. It was only after talking to her that he sensed the chaos.
This kind of situation only had two reasons, first, she was important in this chaos, another one was, the chaos was because of her.
After giving a thought, he thought that the latter wouldn't be possible, how could Ghost Realm be in chaos because of one person. So he concluded that it should be the first reason.
But the one that was impossible, would usually be the cause.
"There's something I don't understand." Sima You Yue said.
"Spill it."
"Even if I'm useful in that chaos next time, I'm not someone who is warmhearted, why teach me?" Sima You Yue asked.
"Because… I'm bored." Mo Yu continued, "Although the Ghost Realm will be in turmoil, to me, it has been peaceful for very long. It's been so long since… I've seen something so exciting."
