Twin female zombies come to the door: My lord, please have mercy!

The morgue is located on the second basement floor of the Fourth Mental Hospital.

The strong smell of blood and formaldehyde mingled in the air.

The black ashes scattered on the ground, now the mutated Blood Corpse King, were still smoldering, a testament to the brutality of the one-sided massacre that had just taken place.

Lin Ye's gaze swept past the mess on the ground and locked onto the crack in the ground in the corner, which was more than half a meter wide.

The pale blue ice crystals spread outwards along the edge of the crack, and the chilling air, like a tangible white mist, churned and surged into the corridor.

The surrounding temperature dropped below freezing, and the walls were covered with frost.

Chu Hongyan leaned against the cold wall, one hand covering the wound under her ribs, panting heavily.

She glanced deeply at Lin Ye, who stood with his hands behind his back, and then at the black-clad woman whose aura was like that of an unparalleled killing god. A storm raged in her heart.

The intelligence network of the General Administration of Abnormal Phenomena covers the whole country, and the information of a prominent legal expert in Jiangnan Province is all in her encrypted terminal.

The young man in front of me, who claimed to be in charge of the funeral parlor, seemed to have a blank background, but the Taoist pure yang talisman technique he used was extremely fierce and domineering.

The woman beside him slapped the A-level mutated blood zombie king to pieces!

"Mr. Lin."

Chu Hongyan endured the excruciating pain and stood up straight, her high ponytail swinging behind her head.

"The source of this rift, which turned the entire hospital into a ghost town, should be below. The Ninth Bureau's support team will arrive in fifteen minutes. It's extremely dangerous down there. I suggest we hold the exit and wait for the main force to take over."

Upon hearing this, Lin Ye turned around and glanced at her.

"Wait for your Ninth Bureau's main force to arrive and close the net, then seal off that extremely Yin spiritual spring below and confiscate it?"

A mocking smile appeared on Lin Ye's lips.

"Deputy Captain Chu, we've only just met, saving your life is an act of good karma. I want the five million reward, and I'll take the stuff down there too. If you're scared, just stay here and wait for reinforcements."

Chu Hongyan's expression changed slightly, and she stepped forward to block Lin Ye:

"The Extreme Yin Spirit Spring is a top-grade containment object derived from the earth's veins! According to the Ninth Bureau's regulations, no civilian organization or individual may retain it privately. Mr. Lin, are you openly defying the Ninth Bureau's regulations?"

"Rules are made by the dead."

Leng Yue strode forward and appeared silently beside Chu Hongyan.

She didn't even turn her head; her deep red eyes were fixed on the dark blue crack in front of her, and an overwhelming pressure of her rank was released.

Chu Hongyan felt as if an invisible mountain was pressing down on her, her knees buckled, and she almost knelt down on the spot.

She was horrified to discover that the spiritual energy she had cultivated for many years was like a mouse encountering a cat, cowering in her dantian and not daring to move in the face of this black-clad woman's mere aura.

"What my lord desires, even the Heavenly King himself cannot stop him. If Bureau Nine is not satisfied, he may come to me."

Leng Yue's voice was clear and cold, like a deity high in the clouds.

"Leng Yue, calm down. If you scare Deputy Captain Chu, who's going to pay our five million reward?"

Lin Ye stepped forward and gently patted Leng Yue's shoulder.

Leng Yue immediately withdrew her oppressive aura, lowered her head slightly, and took half a step back to stand behind Lin Ye, obediently as if the killing god from just now was not her at all.

Chu Hongyan was drenched in cold sweat, her tattered combat uniform soaked through, and dared not utter another word.

"Brother-in-law, it smells so good downstairs! Let's go down quickly!"

Froststar tossed a small bone knife in her hand, her heterochromatic eyes flashing with greedy blue light, urging impatiently.

"Walk."

Lin Ye took out a flashlight and leaped into the dark blue crevice.

Cold Moon followed closely behind, and Frost Star skipped and hopped along behind.

Chu Hongyan gritted her teeth, glanced at the morgue covered in black ash, and then at the dark crack.

Her sense of responsibility as the deputy captain of the Ninth Bureau overcame her fear. She took out a spare fluorescent tube, lit it, and followed along, limping.

……

Beneath the crack lies a hidden world.

What comes into view is a wide cement walkway.

The walls were painted with faded red slogans that read "Dig deep tunnels and store grain widely," and in the corner were piles of ventilation equipment that had long since rusted into lumps of iron.

This is an underground air-raid shelter built in the 1970s.

In order to meet the construction deadline, the location of the air-raid shelter was not chosen to avoid the mass graves in this old city area.

After the hospital was built, the morgue's morgue cabinets were placed directly above the air vents of the air-raid shelter.

"It's so cold..."

Chu Hongyan, who was following behind, shivered.

The cold here cannot be explained by physics.

The beam of the flashlight shone out, and fine blue ice shavings floated in the air.

This chill penetrates directly into the soul, capable of freezing out the vital energy of a living person.

Lin Ye's body was protected by pure Yang energy, and a faint reddish halo appeared on his skin, completely isolating him from the cold.

He glanced at the three-dimensional compass in his hand; the compass needle was completely broken.

The magnetic field here has long since collapsed.

"The White Tiger Carrying Corpse Formation, combined with the intricate network of air-raid shelter pipes, forms a massive 'yin-gathering funnel'."

Lin Ye frowned deeply, analyzing the situation as he walked.

"The extreme yin energy between heaven and earth seeped through the earth's veins and accumulated here for more than half a century. The quantitative change led to the qualitative change, which gave birth to the legendary spiritual spring."

Froststar walked at the very front, as if she had returned to her happy old home.

She opened her arms and took a deep breath of the blue slush in the air.

Those deadly, chilling corpse energies were like a perfect tonic for her, a mutated white zombie.

Her silver-blue twin ponytails glowed faintly in the darkness, and with each step she took, the frost beneath her feet automatically dissipated.

"My lord, there is something alive ahead."

Leng Yue suddenly stopped, her red eyes narrowed slightly, her gaze piercing through the deep darkness.

Lin Ye immediately turned the flashlight beam to its brightest setting and shone it directly at the end of the tunnel.

At the end of the air-raid shelter was an underground domed hall, about half the size of a football field.

In the very center of the hall, the floor has sunk downwards, forming a natural stone pit.

Inside the stone pit, a pool of milky white liquid was emitting a faint blue light.

It contained absolutely no liquid; it was entirely composed of the purest, almost liquefied, primordial yin essence.

Just one glance was enough to make Lin Ye feel his pure Yang body stirring wildly.

Extreme Yin Spirit Spring!

Countless stark white skeletons were scattered on the ground around the spiritual spring.

There were animal figures, human figures, and even a few broken Type 9 assault rifles.

"Be careful!"

Chu Hongyan's pupils contracted sharply, and she gasped in shock.

"Splash!"

The calm surface of the spring water suddenly burst open.

A colossal creature, as thick as a water vat and nearly twenty meters long, suddenly burst out from the bottom of the spring!

It was a giant, one-horned python covered in dark blue scales and with a fleshy growth on its head.

Its eyes were like two huge red lanterns, and with each flick of its tongue, it sprayed out large swaths of deadly dark blue venomous mist.

"A century-old treacherous creature!"

Lin Ye gasped.

This ferocious beast, mutated from snakes absorbing the yin energy of the earth's veins, can transform into a yin dragon after shedding its skin once more, its strength even surpassing that of a flying zombie.

Most of the advance team from Bureau Nine ended up in its belly.

The yin serpent coiled above the spiritual spring, emitting a deafening hiss.

The terrifying sound waves caused rubble to fall from the dome. It stared intently at the intruders, opening its blood-red maw to reveal two rows of dagger-like fangs.

Just then, the system notification sounded in Lin Ye's mind.

"Ding! My Lord, please exercise self-restraint. System notification: The system has detected an encounter with the guardian beast 'Centennial Yin Serpent' that accompanies the Spirit Spring. Please make a choice within three minutes to seize this opportunity!"

[Option A: Strategic retreat – Shouting "We can't win, let's run!", he picked up Chu Hongyan and ran.]

[Reward: Chu Hongyan's favorability +50. Consequence: You will be swallowed whole by the Yin Serpent, turning into its excrement to nourish the spiritual spring.]

Only a fool would choose A or B.

Choose C without thinking.
