The appearance of the black sword similar to the Shenyuan which is also the natal sword of the Sovereign God of Void and Darkness places tension between the God of Destruction and the Sovereign God of Void and Darkness at this moment. It didn't take long for the Hell Flame Lord's soul to be taken over by the Dark Lord. Ye Xiajie's formerly obsidian irises had turned crimson at this moment. His eyes seem to linger on the black sword in his beloved's hands.
The two of them actually know the origin of this black sword. This is the core part of Shenyuan. If Shenyuan is a husk born from the power of the Flame Lord and can slay all other gods then this black sword is the core of the Dark Lord's power. It possessed the darkness and gluttony only the void can possess. It is also the key to the Void world under the control of the Dark Lord.
