Because every time the Soul Capturing Stone was used, it required a massive amount of energy.
And to replenish this energy, it had to absorb the spiritual power from the human brain.
That was to say, after Ye Qianrou used the Soul Capturing Stone to inspect Lin Mengyao's memories,
all the spiritual power in Lin Mengyao's brain would be sucked away by the Soul Capturing Stone.
And once a person's brain was deprived of spiritual power, that person's brain would fall into a deep coma, also known as a vegetative state!
Once in such a state, unless the spiritual power was restored, one would never wake up again.
But restoring spiritual power was easier said than done.
The conditions were extremely harsh, almost impossible to meet.
Therefore, basically, after becoming a vegetative person, it was as good as being sentenced to death.
That was the reason Ye Qianrou had always been reluctant to use the Soul Capturing Stone.
