I am a master of both medicine and martial arts; after my release from prison, I will dominate the w

Gu Shuofeng wasn't a very humorous person, and he felt that his personality had been insulted.

"Chu Yang! Don't talk nonsense! Cough cough cough..."

Perhaps due to his anger and agitation, he coughed up a mouthful of blood.

Chu Yang was taken aback. "I'm not kidding you. Your body is practically exhausted, and you're doing this to save your sister?"

With a sullen face, Gu Shuofeng led Chu Yang into the inner room.

Stepping into the inner room, it was completely different from the gloomy and pungent smell of the outer room.

Under the dim light of the medicine furnace, Gu Shuofeng's younger sister, Gu Shengyao, lay quietly on the bed.

The blood of the Miao people flows through her, giving her a breathtaking beauty.

Her long, black hair cascaded down her pillow, making her small face appear even paler and more translucent.

Her eyebrows, like distant mountains shrouded in mist, furrowed slightly in her sleep, evoking a sense of pity.

Long, thick eyelashes drooped down like butterfly wings.

Her nose was straight and delicate, and her lips were as pale as cherry blossoms, yet this did not diminish her exquisite beauty.

Her beauty possesses an ethereal and fragile quality, far removed from the hustle and bustle of the world, like a rare orchid growing deep in a secluded valley, absorbing the moonlight yet unable to withstand wind and rain.

Even when she was unconscious on her sickbed, the exquisite beauty that came from her bloodline and had an exotic flair was still so intense that it took one's breath away, creating a heart-wrenching contrast with the hideous scars on her brother, Gu Shuofeng.

"This...is this really your sister?"

Chu Yang now feels that genetics is a bit unreliable.

"My grandfather says you might be able to cure my sister. You should check it out. But be careful, the poison in her body might seep into yours."

Chu Yang smiled confidently, "The only poison in this world that can penetrate my body is myself."

He composed himself and lightly touched Gu Shengyao's slender wrist with his fingertips.

Her pulse was weak and thread-like, yet a chilling and sinister poison lurked in her heart, eroding her last remaining life force.

He focused intently on examining his internal organs, his brow furrowing—this was a sign of his life force being depleted due to the backlash from some domineering and sinister energy.

Just then, a faint, chilling aura actually entered his body from his fingertips.

However, he was not flustered. No matter what kind of evil poison it was, as long as it entered his body, it would be neutralized by the extreme yang energy.

But the next moment, his mind trembled violently.

That unknown, chilling energy actually followed a meridian that had been broken through its constraints, and deliberately drilled into the dantian.

"What happened? Your sister...?"

Before he could finish speaking, the jade pendant on his chest began to vibrate violently, a signal that it had sensed the Nine Yin Body.

Chu Yang quickly withdrew his hand and focused his mind on channeling his true energy into the meridians that had just been broken free of their constraints.

Prior to this, he deduced that with his own internal energy, it would take at least three days to break through the shackles.

Unexpectedly, Gu Shengyao's energy just now combined perfectly with his extreme yang energy, producing an excellent effect.

Although only one meridian was unblocked, it was enough for him to release his true energy to give Gu Shengyao a "full body checkup".

Chu Yang stared at Gu Shengyao in disbelief. She lay peacefully on the bed like Sleeping Beauty, without moving an inch.

"Chi Ming said your sister isn't afraid of poisons, but sometimes she uncontrollably releases poisonous gas, killing people before, right?"

Gu Shuofeng immediately said indignantly, "That's not how it is! Yao Yao lost control because those damned bad guys wanted to bully her."

Chu Yang gestured for him to calm down, "Don't get agitated! I'm a doctor now, I just want to know more about the situation."

As he finished speaking, he pointed to Gu Shengyao's chest.

"Her condition is complicated. I need to release some internal energy here to figure out the specifics of her internal condition."

Gu Shuofeng was panting and frowning; his displeasure was written all over his face.

"You...don't touch me like that!"

Chu Yang has now confirmed that Gu Shengyao possesses the Nine Yin Body, and his initial assessment is that she has the Poisonous Yin Body.

Ancient texts describe the Nine Yin Body as having distinct characteristics, but even when they do describe them, the descriptions are vague, mysterious, and difficult to understand.

The description of the Poisonous Yin Body is only briefly mentioned.

It's just that this kind of constitution will bring misfortune.

There was once a person with a poisonous yin body who lost control, causing thousands of people in a town to die from poisoning.

It is estimated that Gu Shuofeng came to this "no man's land" not only to provide Gu Shengyao with a residence rich in yin energy, but also to avoid people as much as possible.

Chu Yang extended a wisp of true energy, slowly circulating it through Gu Shengyao's meridians; everything seemed normal.

Chu Yang also confirmed that Gu Shengyao's physical characteristics were consistent with the "Poisonous Yin Body" recorded in ancient books.

Just as he was about to withdraw that wisp of extreme yang energy, a sudden change occurred.

Gu Shengyao seemed to have her self-protection switch triggered. The powerful true energy in her body spun rapidly like a vortex, constantly pulling the extreme yang energy towards the core.

Meanwhile, the true energy within Chu Yang's body was being pulled outwards like the silk threads of a silkworm.

He currently only has one meridian open, which is no match for such a powerful force.

He knew he would be drained dry if things continued like this.

"Old Gu, seal my pulse points!"

Gu Shuofeng also noticed something was wrong and quickly flicked his finger at Chu Yang's wrist.

Chu Yang's index finger showed that his Yang meridian had been severed, so he quickly took two steps back.

At this moment, Gu Shengyao's eyelashes trembled slightly.

Gu Shuofeng was so excited he almost shouted, "Yaoyao! You...you..."

Chu Yang patted his shoulder. "She's not awake. I just triggered her body's self-protection mechanism. You want to use the poison puppet to save her because you think she needs a lot of poisonous yin energy?"

Gu Shuofeng nodded vigorously: "That's right!"

Chu Yang then asked, "So you created a lot of evil Gu worms, causing your skin to ulcerate?"

"Yes!" Gu Shuofeng made no attempt to hide anything.

Chu Yang frowned and continued, "Chi Ming actually knew you were in the East Sea, and the Gu worms in that box he brought were all cultivated for you. It's just that he couldn't meet you directly, so he chose that girl Tangtang. And you just went with Tangtang and bought the Gu worms from her, right?"

Upon hearing the name Tangtang, Gu Shuofeng's face filled with resentment: "That little rascal is too clever! She even stole some! I can't leave here now, so I have to have her bring them over. But I didn't expect you to run into her this morning."

Chu Yang sighed deeply, pointing to the cold-natured medicinal herbs that Gu Shuofeng had spent a lot of money to buy, and the bottles and jars containing Gu worms neatly arranged on the shelf.

"Giving these things to your sister might seem to stabilize her condition, but it's like drinking poison to quench thirst, or constantly adding explosives to a powder keg. If you give her all the poisonous yin energy of the Poison Puppet, that's when she'll completely explode. I reckon there won't be any living creatures left within miles of her."

Gu Shuofeng frowned deeply, but still asked with resentment, "If I hadn't given her those things, she would have died long ago. You make it sound so easy; show me how you heal her."

Chu Yang's lips twitched, and he said disdainfully, "I didn't expect that you, who seem like a chuunibyou, would know how to use reverse psychology."

When his trick was exposed, Gu Shuofeng blushed.

"Forget it, I can't outsmart someone like you. Since you say the poison puppets and those poisonous creatures can't save my sister, you must know what can. So tell me, are you going to sleep with my sister?"

Chu Yang's lips twitched a few times as he stared incredulously at the immature man in front of him.

"No, can you please not be so rude? I'm a doctor."

Gu Shuofeng scoffed disdainfully.

"Don't think I don't know. After you slept with Xiao Yuening, his entire aura changed. And that Hua Xiyue, after you slept with her, the yin energy within her became..."

"Stop! Stop!"

Chu Yang waved his hand in horror, "You...you saw it?"
