9 That was all Slave Control Was (1/2)

The terrible memories triggered anger in the four guards, and they looked towards He Xi—who was unconscious in the dark corner—with hostility.

One of them suddenly laughed sinisterly. ”The energy in the furnace will run out one day. When there's nothing left to extract from her, will Young Master give two hoots about her? By then, we can give her a taste of living hell.”

That idea made the four people laugh out loud cockily, their gloomy mood from before disappearing.

A murderous look flashed across the eyes of He Xi who was feigning sleep.

She would not let these scumbags get away with it!

Her fingers moved slightly, and invisible needles appeared in her hands.

Under the cover of the guards' laugh, cracking sounds came from her body.

In an instant, her wrist bone contorted; and she broke out of her cuffs effortlessly.

Contortion was a useful skill to have, but anyone who tried to practice or learn it would have to endure inhuman pain. On top of that, the efforts were brief. Only monsters like He Xi could suffer through it.

Her face was pale from the pain, and she rested her slender fingers on her wrist.

So that was what brain control was about!

A confident and bright smile appeared on He Xi's face.

Her guesses were correct. The so-called slave control was nothing but the use of spiritual powers to control the brain functions of mortals.

Slavery bondage was the key to triggering these.

Just like the headband Tang Sanzang put on the Monkey King, the slavery bondage—when triggered with spiritual powers—would put pressure on the human brain, resulting in indisputable pain.

This simple mechanism was useless against those with spiritual powers, but mortals had nothing on it.
