Whoosh.
Xiao Yi, hearing Xiao Lihuo's words, immediately leaped into the sky.
His speed soared to the extreme.
He had just wanted to chase after those two masked Mystic Breakthrough Realm Martial Artists.
But he found they had already vanished without a trace; there wasn't even a hint of their aura left behind.
"Damn it," Xiao Yi gritted his teeth, with no choice but to descend from the sky.
"Yii'er, why aren't you chasing them?" Xiao Lihuo and the other elders crowded around, asking anxiously.
"Can't chase them." Xiao Yi shook his head, his expression grim.
"Erasing their aura, concealing their tracks, they're not ordinary Martial Artists," Xiao Yi said in a deep voice, "They are assassins."
"Assassins, Shadow Tower?" the Xiao Family Elders gasped in unison.
"Probably not," Xiao Yi shook his head.
The speed at which those two masked Martial Artists had fled suggested that their Cultivation was at least above the Sixth-Layer Mystic Breakthrough.
