After receiving his teacher's instructions, Tang Feng left Han Prefecture and headed straight south. After hurrying along for several days, he arrived beneath a low hill outside the Azure Sun Domain.
He brought out the talisman token he carried and followed where it led. At last, his body sank downward, descending through a patch of coarse sand that appeared utterly unremarkable on the surface, and entered an enormous cavern.
The moment he entered below, he saw red and black baleful rivers surging endlessly all around. Following the drifting talisman token for a long while longer, he saw a blurred figure trapped atop a jade disc ahead, enveloped by the qi of heavenly balefulness and earthly malignance, impossible to discern clearly.
His cultivation was inferior to Gongsun Min's. Only after circulating his magical power several times did he cast off the foul, turbid sensation emanating from the Killing Intent. Then, following the method taught by Master Bai Xiu, he began chanting an incantation.
After a while, the entire cavern trembled faintly. Then a streak of white light flew over and landed in his hand. He covered it with the ritual cloth he had prepared beforehand and slipped it into his sleeve. Not daring to linger here, he hurriedly departed.
Not long after he left, the two red-black baleful rivers, which had originally rushed along separate paths on either side, gradually merged together and slowly turned into a stream of deep-purple Killing Intent.
The figure bound atop the great round jade disc had originally remained perfectly still, but now seemed to tremble ever so slightly. The chains locking the person in place gave off a few faint clinks. After a while, everything subsided once more, except the Killing Intent had become even darker and murkier in color.
