Wu Lingyu didn't know about Tan Yun's identity before this either. The two of them had a relatively good relationship, but it didn't mean that they would trade secrets.
Later on when his souls fused, he became more sensitive towards the aura of the devil clan. Only then did he know his true identity.
At that time, he was really surprised. Later on, when he found out about Tang Yun, the two of them became closer.
"The devil realm is rather chaotic right now. If you return, your enemies would probably have no time to chase you down." Wu Lingyu said.
"That's not necessarily true." Tang Yun's eyes flashed with malice, "However, no matter what, I definitely have to go to the devil realm!"
"Mm. Take revenge when it needs to be done."
"You should hurry back to settle the things on that side. This way, there won't be so many loose ends when I return!" Tang Yun said.
"I asked you to return with me but you didn't want to."
