Watching the middle-aged beauty's life essence gradually dissipating, Lu Qing's face remained expressionless.
He had never intended to truly let her go the moment he read the information about the middle-aged beauty.
The reason he didn't kill her immediately was simply that she still had some utility.
Even the poison he had fed her was real.

Had she not taken the antidote within the time limit, the middle-aged beauty would indeed have died a gruesome death from her intestines rupturing.
However, considering that she led the way for him, Lu Qing ultimately chose to let her die without suffering.
After a final glance at the corpse of the middle-aged beauty and using his Superpower to confirm her death, Lu Qing left the secret chamber and exited Zheng Mansion.
But before leaving, he did something else.
"Fire, there's a fire!"
