"Creating a doppelgänger and then replacing oneself with it."
For Su Chengyu, the Immortal from Kunwu's move was infuriating beyond measure.
Yet Su Chengyu hadn't entirely lost his reason; he knew all too well the immense cost of using mana to directly summon the Wasteland Sky Halberd.
Therefore, even when facing the Chaos Demon Ape, Su Chengyu had not forcibly summoned the Wasteland Sky Halberd.
But times had changed; Su Chengyu was well aware that the man in black wasn't making empty threats.
The doppelgänger created from himself on the sixth level was identical to him, to say nothing of the fact that its strength had been enhanced by a realm thanks to the Ascending Heaven Tower.
The only way Su Chengyu could hope to defeat his opponent was with something he possessed that the other did not.
The Heaven-Mending Stone, the Wasteland Sky Halberd.
