Chapter 27: Siege

"Tang Yun! Xiyue! Are you inside?" It was Elder Li's voice.

Tang Yun hurriedly put the Shennong Cauldron and the Martial Dao Stele into his storage ring and opened the door.

"Elder Li, what happened?"

Elder Li's expression was solemn, "Mobei is in emergency! The Three Poison Holy Son of the Heavenly Medical Sect has led an army of one hundred thousand Gu poison soldiers to besiege Mobei; I must return immediately!"

Tang Yun was startled. Mobei was Lin Xiyue's hometown and also the location of the Taixu Sect; if Mobei were captured, the consequences would be unimaginable!

"Xiyue, let's go!"

The two had no time to think and immediately followed Elder Li out of the room.

Outside Mobei City, banners blocked the sun, and the sound of killing shook the heavens.

One hundred thousand Gu poison soldiers were like a tide, constantly impacting the defensive formation of Mobei City.

On the city walls, Taixu Sect disciples were fighting bloody battles, but facing the massive Gu poison army, they gradually felt powerless.

"Tang Yun, you finally returned!" Seeing Tang Yun and Lin Xiyue, Taixu Sect Master Lin Yuanzun flashed a trace of relief in his eyes.

"Sect Master, how is the situation?" Tang Yun asked anxiously.

"Not optimistic," Lin Yuanzun sighed, "The Three Poison Holy Son's strength is unfathomable, and his Gu poison army is even more fearless of death; our defensive formation is about to fail."

Tang Yun looked up and saw scenes of slaughter everywhere on the city walls, with Taixu Sect disciples falling into pools of blood one after another.

"Xiyue, your identity as the Holy Maiden has been exposed; the Heavenly Medical Sect Master, who is also your enemy, is the mastermind behind this attack!" Lin Yuanzun said in a deep voice.

Hearing this, Lin Xiyue's body shook, her eyes filled with flames of hatred.

"Damn beast! I must make him pay the price!"

Just then, a dazzling light suddenly appeared in the sky, shooting straight into the clouds and illuminating the entire battlefield.

"What is that?" Everyone looked up one after another.

"It's the peak of Tianshan! The third divine artifact, the Medicine King Sword, has appeared in the world!" Lin Yuanzun said excitedly.

However, this excitement didn't last long; the light at the peak of Tianshan suddenly dimmed, and an eerie aura shrouded the entire sky.

"Not good! The Heavenly Medical Sect is using the Three Yin Soul-Gathering Formation to suppress the Medicine King Sword!" Lin Yuanzun's expression changed drastically.

Tang Yun's heart sank. The Three Yin Soul-Gathering Formation was an extremely evil formation that could absorb the yin energy between heaven and earth to suppress divine artifacts, and its power was extremely great.

"Must break the Three Yin Soul-Gathering Formation as soon as possible and take back the Medicine King Sword!"

Tang Yun took out the Shennong Cauldron and continuously injected his True Qi into it.

"In my name, draw upon the power of the Earth Vein!"

The Shennong Cauldron emitted a dazzling light, the earth began to shake violently, and a powerful force surged from deep underground, impacting the Three Yin Soul-Gathering Formation.

At the same time, Lin Xiyue also activated her Taixu bloodline, and a white light radiated from her body, merging with the power of the Shennong Cauldron to form an even more powerful force, constantly impacting the seal of the Three Yin Soul-Gathering Formation.

The seal of the Three Yin Soul-Gathering Formation began to show cracks, and the eerie aura gradually weakened.

"Now is the time!"

Tang Yun took out the other divine artifact he had obtained earlier, the Xuanyuan Sword, and together with Lin Xiyue, activated their Internal Energy. The two forces merged to form a huge sword aura, slashing toward the seal of the Three Yin Soul-Gathering Formation.

"Boom!"

With a loud bang, the seal of the Three Yin Soul-Gathering Formation was finally broken, and the Medicine King Sword descended from the sky, landing in Tang Yun's hand.

The moment the Medicine King Sword recognized its master, a line of text suddenly appeared on the sword body: My son Tang Yun, Mother has failed you...

Tang Yun's heart shocked; this line of text was clearly his mother's handwriting!

He hurriedly checked the sword body and discovered that some small characters were also engraved on it; these characters were actually remnant pages of his mother's diary!

"I... am I the true successor of the Heavenly Medical Sect?"

Just as Tang Yun was shocked, the Three Poison Holy Son suddenly appeared in front of him, a cold smile on his face.

"You are just a container for the Poison King; are you worthy of owning the Medicine King Sword?"

"I have the final say!" Tang Yun roared, the Medicine King Sword shone brightly, its sword aura like a rainbow, directly slashing the Three Poison Holy Son away, causing him to fall heavily on the city wall, spitting blood.

"You... you actually..." The Three Poison Holy Son struggled to stand up, only to find that his meridians had been shattered by the sword aura, unable to fight again.

Tang Yun ignored him and turned to look at Lin Yuanzun, "Senior, we must head to the peak of Tianshan as soon as possible to take back the Nine-Turn Golden Core!"

Lin Yuanzun nodded, "No time to lose, Xiyue, you go with Tang Yun, others stay to guard the Taixu Sect and resist the attack of the Heavenly Medical Sect!"

Lin Xiyue gripped the Medicine King Sword tightly, a flash of determination in her eyes, "Yes, Master!"

The two didn't hesitate, directly activating the Taixu Mirror, and with a flash of white light, they instantly disappeared from where they were.

The peak of Tianshan, the cold wind was biting, and the snow was white.

As soon as Tang Yun and Lin Xiyue appeared, they felt a powerful pressure, as if the entire world were repelling them.

"Such strong yin energy!" Lin Xiyue couldn't help but shiver.

Tang Yun nodded, his gaze scanning the surroundings, finally locking onto an ice wall.

"The Nine-Turn Golden Core is there!"

He held the Medicine King Sword and slashed fiercely at the ice wall.

"Boom!"

With a loud bang, the ice wall split open, revealing an ice cave hidden within.

The two entered the ice cave and discovered that there was a world within, a huge formation running, exuding an eerie aura.

"'Great Wilderness Formation'!" Lin Xiyue exclaimed.

In the center of the formation, a golden, shining pill was suspended in mid-air; it was the Nine-Turn Golden Core!

"Damn Heavenly Medical Sect, actually using such an evil formation to suppress the Nine-Turn Golden Core!" A flash of anger crossed Tang Yun's eyes.

"Tang Yun, I will break the formation!" Lin Xiyue held the Medicine King Sword, stood in the center of the formation, bit her finger, and dripped a drop of fresh blood onto the sword body.

"In my name, with my blood, break!"

The Medicine King Sword emitted a dazzling light, and a powerful force erupted, impacting the formation.

The formation vibrated violently, emitting bursts of wailing sounds, finally shattering with a loud bang.

However, just as the Nine-Turn Golden Core was about to fall into Tang Yun's hand, an unexpected change occurred!

The golden core suddenly turned into a ball of blood-red liquid, like a flexible poisonous snake, instantly burrowing into Tang Yun's heart!

"Tang Yun!" Lin Xiyue exclaimed, hurriedly stepping forward to check Tang Yun's condition.

Tang Yun's face was pale, his body trembling, and a cold aura radiated from his body.

"This is... Poison King Essence Blood!" Lin Xiyue's expression changed drastically; she recognized the source of this aura.

Just then, a series of low roars suddenly came from the depths of the ice cave.

Immediately following, illusory figures emerged from the depths of the ice cave; these figures were in various forms, but all exuded powerful auras.

"Residual souls of past Medicine Kings!" Lin Xiyue exclaimed. ===== CHAPTER 28 =====
