"How did you know that the Ghost Concubine collaborated with Qing Hun?" Di Zhe asked.
"Mu Lan told me." Sima You Yue said.
"Seems like the network of the Abyss of Hell on Ghost Realm is better than we expected." Di Zhe said. "We received this information recently, but because of the current situation, it's useless to reveal it. And there wasn't any strong proof."
"Mu Lan was also being friendly by revealing this information. And it could only hold on this long because he promised to give me three months' time and promised that Qing Hun wouldn't attack the Ghost Realm in that period of time, so I could save Mother." Sima You Yue continued, "But Ghost Concubine is still around, it's tough."
"No wonder Qing Hun has been keeping watch outside for over three months without attacking. I thought he had some trick up his sleeves, I didn't think there was such a thing." Di Zhe finally understood why the odd occurrence.
