Black Mist Dragon Wind had been part of Yang Chen's plan all along.
The first time he had entered Forbidden Demon Clan territory, he and his team had encountered this Black Mist Dragon Wind. Back then, Yang Chen had used the Nine-Star Gourd to absorb it because he knew it would serve a great purpose.
However, the Black Mist Dragon Wind had to be used within ten days, or its power would be greatly diminished. Fortunately, Yang Chen's luck was not too bad; he had finally managed to use it within those ten days.
Now, the Black Mist Dragon Wind leaked out of the Nine-Star Gourd at full force. As it appeared across the battlefield, every member of the Forbidden Demon Clan was left dumbfounded.
"Black Mist Dragon Wind, it's the Black Mist Dragon Wind!"
"What's going on? How could the Black Mist Dragon Wind appear here? What is happening?!"
Though Tiger Saber Demon King did not know by what principle the Black Mist Dragon Wind had appeared, he knew this matter was inseparably linked to Yang Chen!
"Where is that brat?" Tiger Saber Demon King wanted to find Yang Chen, but just as he prepared to cause trouble, he discovered that Yang Chen had already vanished without a trace.
How could Yang Chen possibly have stayed here? The Black Mist Dragon Wind released by the Nine-Star Gourd did not emerge in an instant, but continuously. Thus, while releasing it, he had enough time to escape. Had he delayed any longer, even he would likely have been swept into the Black Mist Dragon Wind.
Now that Yang Chen had fled, it meant the Black Mist Dragon Wind had completely unfolded.
"Demon King, this is terrible! The Black Mist Dragon Wind is sweeping over here!"
"Demon King, quickly think of something!"
