The plea for help from Hu Xiao came too suddenly, connected to that brief fluctuation just now, it could even be described as abrupt.
But the fleeting fluctuation that passed a moment ago convinced Su Chengyu that it was unlikely to be a trap set by Hu Xiao.
Indeed, it would be an excellent choice to act against himself at this moment, but such commotion, Su Chengyu really didn't believe Hu Xiao was capable of causing.
Without hesitation, holding the Dragon Slayer Sword, Su Chengyu soared into the dense forest.
The enclosing Demonic Qi instantly wrapped around Su Chengyu, causing him some discomfort.
This situation was the most direct representation of Su Chengyu's current mana depletion, but fortunately, the Dragon Slayer Sword was becoming more and more attuned to human nature.
Upon noticing the anomaly in Su Chengyu's body, it promptly enveloped Su Chengyu completely with its Sword Qi, isolating his aura from the external environment to prevent any unforeseen complications.
