The Only Clue

Before a black tide completely swallowed her consciousness, the female doctor tried to resist desperately.

However, she immediately felt ten thousand electrified steel needles ruthlessly pierce into her entire spine.

Several thousand bolts of lightning flowed through her central nerves and into her limbs and bones, controlling every strand of muscle fibers and every cluster of nerve endings. It made her instantly lose all mobility, including the ability to blink.

'How is this possible?

'Is this guy really a ghost? When did he get behind me and cause me to instantly lose all ability to resist?

'Who is he? Who is he?!'

The female doctor's hair stood on end.

She made a prompt decision and gave up the thought of resisting.

She poured the last of her strength into her heart.

Then, she tried to control her heart, getting it to beat at a rate of more than two hundred beats per minute.
