From the Iron Shirt Technique to physical sanctification

Zhang Yu wasn't confident and didn't want to make a move, but Su Lingxi insisted on getting close, so he decided not to hold back.

The ropes binding him broke silently.

With lightning speed, his right hand grabbed the other person's neck, while his left palm struck the other person's dantian (lower abdomen).

boom!

This palm strike was incredibly powerful, instantly shattering Su Lingxi's entire body's energy and leaving her severely injured.

With a "poof," Su Lingxi spat out a large amount of blood.

【With the wind】

As Zhang Yu grabbed Su Lingxi by the neck, he instantly activated his speed, lifting her body and swaying as he arrived at a corner of the secret room, hiding behind her.

All of this happened in an instant.

Because it happened so suddenly, by the time the old woman reacted, Zhang Yu had already finished everything.

Su Lingxi was seriously injured and coughed up blood. Zhang Yu locked her neck, hid behind her, and stared at the old woman.

"You little beast, you're asking for it!"

"You old bastard, try moving." Zhang Yu's fingers dug into Su Lingxi's neck, making a cracking sound. At this moment, Su Lingxi's face turned red, and her hands and feet began to struggle unconsciously.

Life and death were separated by a hair's breadth.

"If you dare to move an inch, I'll snap her neck right now."

The old woman, who had already taken a step, suddenly stopped.

"You dare!"

"Heh, do you want to give it a try?" Zhang Yu's eyes were cold and devoid of any emotion.

"If even a single hair on the Holy Maiden's head is missing, I'll make you wish you were dead!" The old woman roared, but dared not move another step.

She saw indifference towards life in Zhang Yu's eyes.

"This man really dared to kill the Holy Maiden!" she thought to herself.

Click!

Uh...uh...

Zhang Yu suddenly twisted Su Lingxi's arm into a pretzel, with bone fragments piercing through the flesh and exposing it bloodily.

The intense pain caused Su Lingxi, who was on the verge of suffocation, to let out a series of groaning sounds, and she completely broke down.

Zhang Yu stared at the old woman expressionlessly, his voice icy: "Didn't you want to make me wish I were dead? Come on!"

Zhang Yu then picked up Su Lingxi's other arm.

"No!" the old woman cried out in fear.

That madman.

"If you release the saintess, I can let you leave." The old woman admitted defeat.

She dared not gamble; the Holy Maiden was the future of the Heavenly Heart Sect, and absolutely nothing could happen to her.

When Zhang Yu took action, he already considered himself a dead man. His psychological change began after the massacre of the Wild Wolf Gang, especially after eliminating several young children, which instilled a sense of indifference towards life in him.

This indifference is not only directed at the lives of others, but also at his own.

"If you destroy your dantian, I will release the person," Zhang Yu said.

"Impossible!" The old woman wasn't stupid either: "I swear, as long as you release the saintess, I'll let you leave immediately."

"Hehe!" Zhang Yu chuckled.

Neither of them was stupid, and neither could do anything to the other. The old woman was hesitant to act rashly, and Zhang Yu didn't dare to really kill Su Lingxi, so they could only remain in a stalemate.

Li Feifei woke up.

She didn't open her eyes, remaining motionless on the ground, quietly listening to Zhang Yu's conversation with the old woman.

Li Feifei quickly figured out what had happened and her current situation.

"As a martial artist at the Qi Refining Realm, what can I do to help Senior Brother Zhang Yu?" she thought rapidly.

Time passed by, second by second.

Zhang Yu was locked in a stalemate with the old woman. Although he had Su Lingxi under control, the old woman was not easy to deal with.

The other party blocked the entrance to the secret room, refusing to budge an inch.

Zhang Yu twisted Su Lingxi's other arm into a pretzel shape and deliberately loosened her neck slightly, causing Su Lingxi to scream in pain.

Ah... Ahh...

The pitiful screams filled every inch of the secret room.

Unfortunately, this still did not sway the old woman.

The other party isn't stupid.

The old woman dared not kill Zhang Yu, fearing a lose-lose situation, but she also wouldn't let him go, knowing that Zhang Yu wouldn't dare kill Su Lingxi until the very last moment.

"What should we do?" Zhang Yu's expression remained unchanged on the surface, but he was extremely anxious inside because he realized that there seemed to be no good way to escape.

Just then, Li Feifei, who was lying on the ground, suddenly made a sound.

"My head hurts so much. Huh? Where am I?" Li Feifei opened her eyes, covering her head with both hands, looking like she had a headache.

Her awakening immediately attracted the attention of Zhang Yu and the old woman.

The old woman moved, and Li Feifei was grabbed by the neck and lifted up: "Release the Holy Maiden, or I'll break her neck right now."

Zhang Yu's heart skipped a beat. He glanced at the old woman, then looked at Li Feifei.

Li Feifei's face was flushed and she was having difficulty breathing, but when Zhang Yu looked at her, her eyes blinked slightly.

Zhang Yu's mind raced: "What is Li Feifei trying to do?"

"What did she mean by blinking just now?"

"What should I do?"

After spending this time together, Zhang Yu had come to understand Li Feifei; she was someone who dared to gamble with her life.

"Gambling with my life?" Zhang Yu silently murmured these two words to himself.

He didn't know what Li Feifei was relying on, but he had no choice but to trust her now.

Continuing the standoff with the old woman for too long will become increasingly disadvantageous for him.

Zhang Yu steadied himself, his cold indifference unchanged. He looked at the old woman and said, "Alright, let's both break their necks together."

As he spoke, he began to increase the pressure in his hands, and Saintess Su Lingxi's neck began to bend, making a cracking sound.

Zhang Yu's eyes were fixed on the old woman.

The old woman was also staring at him.

The two began to exert force at the same time, and Su Lingxi and Li Feifei's necks bent one after the other, making cracking sounds as if their bones could not withstand the pressure.

What matters now is not strength, but mentality.

Finally, when Su Lingxi's body stopped struggling and drooped limply, the old woman couldn't bear it any longer.

"Stop, I give up!" The old woman released Li Feifei's neck.

Just as she loosened her grip, Li Feifei, who was already on the verge of death, suddenly felt a flash of cold light on her right hand, and a jade hairpin slashed through the skin on the back of the old woman's right hand.

Uh...

boom!

The old woman then threw Li Feifei out, where she slammed against the wall of the secret room with a loud thud.

puff……

Li Feifei coughed up blood and collapsed to the ground, her life hanging in the balance.

Zhang Yu's expression remained unchanged regardless of Li Feifei's life or death. Only if he lived did Li Feifei have a chance of survival; worrying now was utterly useless and would only disturb his peace of mind.

He stared at the blood on the back of the old woman's right hand, wondering why Li Feifei was desperately creating opportunities to cut the other woman's skin.

poison?

Zhang Yu secretly speculated in his heart.

The old woman saw that the saintess in Zhang Yu's hands had begun to breathe and her neck was no longer twisted, and her heart, which had been pounding, began to relax slightly.

She glanced at the wound on the back of her right hand. It was shallow, with a little blood flowing out, but there was a tingling sensation at the wound.

poison?

She wasn't stupid; she immediately circulated her inner energy to try and force the poison out, but the next moment, her expression changed drastically.

When the true energy circulated to the back of her hand, it not only failed to expel the poison, but instead acted like oil being heated in a fire. The poison, which was originally spreading very slowly, suddenly attacked her internal organs along with the true energy.

"This...this is Corpse Blood Poison!"

As the old woman spoke, foul-smelling black blood began to flow from her mouth.

The potency of the poison left Zhang Yu speechless.

The old woman turned her head to look at Li Feifei, who lay in the corner, her life hanging in the balance, and her eyes flashed with hatred.

With a wave of his hand, a powerful palm strike shot towards Li Feifei's body.

Before she died, she wanted to grind Li Feifei's bones to dust.
