Bai Wei had anticipated Ulu's reaction all along.
After all, Ulu was not really a fool; each time he used Bai Wei's power, his body would noticeably deteriorate, especially this time. Bai Wei had descended for the longest period yet, also employing the Rule of the Middle Finger, which had drained Ulu's already frail body, turning even the blood he vomited black.
If he had not realized it by now, Bai Wei would have to wonder if the host he had attached himself to was actually an idiot.
And Ulu's reaction after guessing the truth was also within Bai Wei's expectations. Once Ulu knew that Visas's power would devour life, he would definitely try to cut off his finger without hesitation, just as he was doing now.
But Bai Wei would not give him the chance.
When his own left hand choked him against the wall, Ulu was terrified and desperate. And it wasn't just the left hand; he felt as if half of his body was beyond his own control.
