Apart from being injured, Shangguan Lei's most serious problem was actually the poison from the plague.
However, this was not an issue for Ling Xiao.
He absorbed all the poison from the plague, using it to nourish the Plague Demon King's Martial Soul.
Before long, Shangguan Lei regained consciousness from his coma.
Upon seeing Ling Xiao, Shangguan Lei immediately relaxed, then asked in surprise, "Junior Brother Ling, what about the Plague Demon King?"
Ling Xiao replied indifferently, "Dead!"
He didn't explain further, and Shangguan Lei didn't dare to ask more.
Shangguan Lei was well aware that his junior brother had many secrets; the less he knew, the better off he would be.
He had resolved that he would definitely not become enemies with Ling Xiao in the future. Although he didn't know how the Plague Demon King had died, he was certain it must have been by Junior Brother Ling's hand.
Before he passed out, he had distinctly felt an extremely terrifying presence.
