Lin Chen shook his head: "No, if anyone stays, it should be Yao Hui and me. How can we let you, a girl, stay alone!"

Yao Hui's eyes flickered, but he snorted coldly: "In terms of speed, I'm the fastest. I can go get reinforcements for you."

Hearing Lin Chen's words, the others had disdain in their eyes, clearly seeing this guy as afraid to die and unwilling to stay.

"Lin Chen, take the crystal stone back with you. Have you forgotten your promise to me?" Yu Feifei said angrily.

"But!" Lin Chen looked at the approaching martial artists, his brows furrowing tightly.

Seeing the pursuers getting closer, Yu Feifei became anxious. Suddenly, she pulled out a dagger and held it to her throat.

"If you don't go, I'll take my life right here."

"Feifei, don't do anything foolish." Jia Xiaoling's face also changed.

"Go quickly." Yu Feifei shouted at them.

Due to being overly emotional, Yu Feifei already had a blood mark on her neck.

"Fine, we'll go." Lin Chen gritted his teeth and finally said to the other two.

Seeing Lin Chen relent, Yu Feifei finally let out a long breath.

She turned around, and a flute appeared in her hand.

The breeze blew, her hair danced, Yu Feifei watched their receding figures, with a slight smile on her lips.

"Lin Chen, you must return to the Medicine Sect alive! Though we are not fated in this life, let's meet in the next."

"Whoosh whoosh whoosh!" Not far away, silhouettes rapidly approached, soon within less than a hundred meters from Yu Feifei.

Once again looking in the direction Lin Chen and the others left, the tenderness in Yu Feifei's eyes disappeared instantly, replaced by a cold look as she gazed at the pursuers.

The Ghost King walked out from the crowd, looking at Yu Feifei standing proudly, a sinister smile on his lips.

"Girl, do you think you can stop us on your own?"

"Tsk tsk, boss, this girl looks pretty good, why not take her back and make her your wife?"

Boom!

Amidst the crowd, there was a burst of eerie laughter.

"Enough nonsense with her, kill her, the Sky Source Crystal must be on Lin Chen." The Ghost King said coldly.

"None of you will leave." Just as they were about to move, a cold voice rang out.

As the voice fell, powerful energy burst forth from Yu Feifei's body.

Yu Feifei bit her jade finger, and a drop of essence blood instantly entered the jade flute in her hand.

The jade flute turned blood red in an instant, and strands of energy surged into the flute.

"Something's wrong, this girl is tricky, kill her quickly." The Ghost King's eyes focused as he suddenly shouted.

Whoosh whoosh whoosh!

Several figures charged toward Yu Feifei almost simultaneously.

At the same time, a melodious flute sound rang out.

"Ah, ah, ah!"

The black domain experts charging at Yu Feifei all clutched their ears in pain, fell to the ground, and died bleeding from their seven orifices.

"Sound Wave Technique!" The Ghost King's face suddenly changed.

Seeing the fallen disciples, everyone's expressions changed.

The ones who fell were all at the early True God Realm, top-tier experts in the black domain, yet they died so bizarrely.

"Damn it!"

Beside the Ghost King, a burly man saw the fallen experts, his face darkened further, and he flashed forward with his fist aimed at Yu Feifei.

The attacker, Zhang Feng, was at the high stage of the True God Realm, second only to Song Qiao among the black domain experts.

Zhang Feng's palm struck the wind, hitting Yu Feifei hard.

At this moment, the melodious flute sound rang out again.

Bang!

Along with a muffled sound, the sound waves and Zhang Feng's iron fist collided fiercely.

To everyone's surprise, the powerful Zhang Feng was actually knocked back by the sound waves, landing heavily on the ground.

Zhang Feng stood up, spitting out a mouthful of essence blood, looking at Yu Feifei in astonishment.

The surrounding people were also shocked, for Zhang Feng, so terrifying in strength, was defeated by Yu Feifei in one move.

This girl was even more terrifying in strength than Lin Chen just now.

The Ghost King stared closely at Yu Feifei: "I didn't expect one of the four divine artifacts, the Demonic Flute, to be in your hands."

Yu Feifei lifted her beautiful eyes, looked at the Ghost King, and smiled faintly: "You have good eyesight, congratulations on getting it right."

"Little girl, your flute is powerful, but it's far from enough to stop me, the Ghost King." He said as he waved his hand.

"Charge, using the Sound Wave Technique requires internal energy. Let's see how long she can last."

With that, the Ghost King darted like lightning towards Yu Feifei, his palm crashing into the sound waves she produced.

The others also launched their attacks, one after another striking the sound waves heavily.

Pfft!

Yu Feifei's mouth was stained with essence blood.

"Qi Huang removes demonic sound!"

A gentle voice echoed from Yu Feifei, and the almost collapsing sound waves recondensed.

The melodious flute sound passed through the forest, reaching Lin Chen's ears.

Lin Chen's body paused, he stopped in his tracks, turning back to look behind him.

"Jia Xiaoling, go find reinforcements quickly, I'm going back to save Feifei." Lin Chen said in a deep voice.

"But Lin Chen, there are too many of them. If you go back, it might be too late." Jia Xiaoling sighed.

"I believe she can hold out until I return." With that, Lin Chen turned to leave.

"Wait a moment." A cold voice rang out at this time.

Lin Chen stopped and said calmly: "What, are you coming back with me to save Feifei?"

"Well, well, since you're going back, give me the Sky Source Crystal." Yao Hui said, thick-faced.

Hearing Yao Hui's words, Lin Chen's gaze turned cold, and he sneered: "If you want the Sky Source Crystal, come back with me."

"This!" Yao Hui blushed. Going back now was akin to seeking death; he naturally wouldn't go back.

"If you don't have the guts, then get lost." Lin Chen snorted coldly and ran madly in the direction from which he came.

"Lin Chen, you must bring Yu Feifei back."

"That idiot, he's just handing over the crystal stone to those people." Yao Hui cursed in anger.

Jia Xiaoling glanced disdainfully at Yao Hui: "Yao Hui, I despise you; you're not worthy of being a man."

With that, Jia Xiaoling ignored Yao Hui and quickly rushed out of the forest.

Yao Hui was humiliated by Jia Xiaoling, his face turned iron blue in rage, yet he was speechless. Indeed, his actions were very unmanly.

In the forest, a melodious flute sound kept coming, but it had become a bit urgent, and the sound waves were no longer very stable.

Boom! Boom! Boom! One attack after another struck the sound waves.

By now, the sound wave attack had already shown cracks.

Finally, Yu Feifei spat out a mouthful of essence blood, and the melodious flute sound finally disappeared without a trace.

"I didn't expect you to grasp the Qi Huang Internal Canon, but unfortunately, today this will be your grave." The Ghost King's face was ferocious as he stared at Yu Feifei.

Yu Feifei wiped the blood from her mouth but smiled faintly: "Being able to hold you off and letting Lin Chen and the others escape, I can die without regret."
