"I've conquered the 'Portal Armor'!"
But this victory is likely only temporary, perhaps even a one-time success.
Even with the most unique defensive tactics, Chen Long is essentially a demon hunter who underwent monstrous transformation surgery to enhance his physical combat skills, so his methods of perception have clearly focused on greatly strengthening his original physical senses. But before he betrayed Luo Mountain, he was an Evil of an achieved level, a veteran of countless battles, and I don't think his perceptual methods are limited to visual and auditory senses, among others. He must have been using—and probably has already been employing—spells for reconnaissance to compensate for the disadvantages of his physiological senses.
Once he realizes how I've conquered his 'Portal Armor,' he will surely abandon relying on visual means and switch to using spells for perceiving his environment, then become invulnerable once again.
I must kill him before he can regroup.
