The Ambitious Succubus Archduke, Stealing the Devil Energy

"As I said, I'm not the only one you've underestimated here."

Upon hearing Chu Kuangren's words, Black Feather Archduke's gaze immediately landed on Succubus Archduke. "It's you. You're the one who's responsible for this poison!"

Among the three Devil Archdukes, Succubus Archduke was the one who specialized in the use of poison.

A seductive smile appeared on Succubus Archduke's face. "Yup, that's right. I'm the one who poisoned you. What do you think? This Devilish Chaos Technique of mine is not bad, right?" 

"When did you do this?"

"Before I arrived."

"It's our King's body! You've poisoned our King's body!"

Black Feather Archduke was confident that there was no way Succubus Archduke would poison him without him noticing. The only possibility was that she had poisoned the Devil King's body before arriving, which meant that she was on to him from the start.

'No, that's not right. Does she plan to scheme against our King?'
