Before Yang Xiao could continue the experiment, a figure already lunged forward, that Shuttle Spear fast as lightning, slicing through the air with a piercing hum.
Just as it was about to pierce Yang Xiao, a gleam of cold flashed in the old man's eyes, and in the next second, the spear tip snapped off and vanished.
Simultaneously, the vanished spear tip reappeared behind Yang Xiao, aiming at him in a downward diagonal stab.
This was entirely the old man holding back, for he dared not truly kill Yang Xiao, otherwise the great expert watching the battle would not spare him.
He was too familiar with the ways of the Esoteric Sect and the Yin Temple people; their words and promises were no different from farts, all prioritizing benefits above all.
He dared not kill Yang Xiao, and even if possible, he didn't want to severely injure this young man.
But now, there was really no choice; if he held back, he would be the first to die.
