Since the last time Tang Yin refined Killing Intent, he had slaughtered thousands of Demonic Beasts and hundreds of cultivators. The newly accumulated Killing Intent around him was even thicker than last time.
Tang Yin thought back to the Ethereal Slaughter Art, although he already knew the Martial Skill by heart, it would not hurt to double-check.
After going through the Ethereal Slaughter Art once more, Tang Yin swiftly started the process of refining Killing Intent.
Dense Killing Intent surrounded him and surged into his body through his pores. This Killing Intent was not under his control, rather it had been accumulated by all the slaughter he had committed.
Tang Yin imprinted his will into the new Killing Intent and fused them together. As he did this, the amount of Killing Intent under his control slowly increased.
