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.
Unfortunately for them, they ran into He Xi!
In her previous life in the organization, she had a mind control ability that everyone was afraid of. That was on top of her medical skills and proficiency with poison.
The insertion of a single needle into an enemy's brain would leave them begging for mercy at her feet.
Brain control was child's play to her.
The needles went into her brain precisely. A cold sensation, coupled with sharp pain, resonated in He Xi's brain.
She gritted her teeth to prevent herself from making any sound that would alert the guards.
The insufferable pain lasted three minutes. He Xi felt her drifting consciousness clear up, and everything felt clear and comfortable.
He Xi pulled out the needles, and all three needles had a blue glow to them.
The creepy, eerie aura passed through the air.
This was the controlling spiritual power that was latent in her brain originally, but it felt different from regular spiritual powers.
The carriage rocked and screeched to a halt.
They were at the Zhu Mansion!
He Xi did not have much time for thinking so she tossed both her needles and the spiritual power into her space. She used the chain to restrain her hands again and closed her eyes to feign unconsciousness.
The golden cage, which contained a disheveled and unconscious young girl, was carried off the carriage.
Zhu Zhongba waved dismissively. "Carry her to my room and get Uncle Guan to bring up the elixirs that he has prepared. I want to increase my cultivation tonight and aim to get to the Foundation Establishment!"
His eyes swept across He Xi and glistened with excitement. "I'll give Father a shock when I've attained Foundation Establishment before heading home. We'll see if he'll call me useless in the future!"
