Su Heng squatted on the ground, closely observing the experimental subject at his feet.
Although the successfully developed potion had removed the mutated state from the subject's body, the excessive consumption of Life Force and the damage caused to the brain's nerves were irreversible and beyond Healing.
Under the effect of nerve reflexes, the half-human, half-Demon experiment twitched its limbs a couple of times.
Its mouth seemed to be muttering something, but before Su Heng could hear it clearly, its pupils slowly dilated, and it completely fell into a deep sleep.
"In this world, humans' lives are indeed fragile," Su Heng murmured. He then administered the remaining potion to other experimental subjects. These subjects were relieved of their mutated states, but without exception, none of them survived. Su Heng did not feel sorry for such results. His approach was a thunderous operation; there weren't many surviving mutated beings left on this continent anyway.
