The temperature around them seemed to instantly become even colder, chilling to the bone!
Old Master Cheng's aura grew more and more intense, his murderous intent soaring into the sky, becoming extremely violent, even stronger than the Sword King by quite a margin!
He strode towards the Alchemy Room, his steps light yet somehow deeply substantial, each step seeming to increase the strength of his aura.
If he struck, it would undoubtedly be a deadly blow!
For an old hand like Old Master Cheng, leaving any sort of hidden danger was absolutely out of the question.
At that moment, Su Han inside the Alchemy Room suddenly looked up, his eyes fixed on the door, his face gradually growing colder.
"A master!" His eyes sparkled with light, sensing that the aura was even more powerful than the Sword King's.
Was this person here to kill him?
