Sure, here is the English translation based on your instructions:
Having revealed his true power, Wang Yan no longer posed any threat or mystery in Li Ji's eyes.
Li Ji said he would kill Wang Yan with one move, and it was not mere boasting.
With his magic power of Great Perfection acquired over hundreds of years, the Demon Venerables who died at his hands were countless, and more than a dozen were killed in a single move.
And today, Wang Yan was just another among them.
Li Ji raised his right arm, swung his right punch towards Wang Yan, and said coldly, "Watch closely, I'm going to attack."
But Wang Yan gestured with his hand and said, "Wait a moment."
Upon seeing this, Li Ji revealed a hint of disdain on his face, saying, "Could it be that you're about to admit guilt and surrender?"
Not only Li Ji but the remaining Demon Venerables also laughed mockingly.
Having witnessed Li Ji's power, this Demon Wolf King had finally realized fear.
