1: Chapter 1 Immortality and Reincarnation

The first thing Li Changsheng felt upon waking up was hunger.

He was so hungry his stomach was cramping, his vision was blurring, and he felt like gnawing on the bedboard.

This wasn't right.

He clearly remembered being on his way home from working overtime when he saw a shooting star crash down, and then...

Wait.

A flood of memories surged forth.

Li Changsheng, sixteen years old, a member of the Li Family in Qinghe Town, Yunzhou. Three days ago, he suffered a Qi Deviation during cultivation; his Meridians were damaged, and his Realm plummeted...

"Transmigration?"

He propped himself up on the bedboard to sit, but heard a loud "gurgle"—not from his stomach, but snoring from the next room.

Then, an even more absurd fragment of memory flashed through his mind:

"He was shackled by the Black and White Impermanence, walking toward the path of Reincarnation. By the River of Forgetfulness, Granny Meng was mechanically ladling soup. The Magistrate flipped through the Book of Life and Death, his vermilion brush hovering over his name, about to strike."

Then, the sky cracked.

"A golden light split the dome of the Netherworld Hall and crashed directly into his Soul body. He heard an ancient voice carrying an Aura that looked down upon the world."

"My Dao is not solitary; longevity is within reach."

When he opened his eyes again, he was lying here.

Li Changsheng felt his intact stomach. Just as he was about to process these absurd memories, a sudden heat flared deep within his Soul.

[Detected that the host's Soul body contains the Dao of Longevity. Binding conditions met...]

[Reincarnation Simulation System, binding successful!]

Li Changsheng froze.

Then, lines of pale blue text appeared in his mind:

[This System can consume Mental Energy to simulate life trajectories in different worlds for the host.]

[After the simulation ends, the host can inherit one achievement or ability from the simulated life.]

[Current host Mental Energy: 10 points]

[Single basic simulation cost: 5 points of Mental Energy]

[Begin the first Reincarnation simulation?]

Li Changsheng took a deep breath.

His Meridians were currently damaged. According to Family records, it would take at least three years of quiet recuperation to recover. Furthermore, it would leave hidden injuries, affecting his future martial progress.

Three years?

It would be far too late by then.

"Begin."

[Ding! 5 points of Mental Energy consumed. The first Reincarnation simulation begins!]

[Randomly selecting simulation world...]

[Selection successful!]

[Simulation World: Low-Martial · Medical World]

[Simulation Duration: Approximately 25 years]

The moment his consciousness was pulled away, Li Changsheng felt himself falling into a surging river.

When he opened his eyes again, he had become another person.

The North, Huaishu Town, a snowy night.

At the moment Sun Yan was born, his mother died from a difficult labor.

His father held the blood-covered infant, standing outside the delivery room, watching the falling snow in silence for a long time.

"I'll call you... Yan."

His father said, "A rock is tough; it lives long."

Sun Yan identified herbs at three, memorized prescriptions at five, and learned acupuncture at seven.

His father was a famous physician in the town and was exceptionally strict with him. For every wrong herb memorized, he received three strikes of the ruler on his palm; for every wrong Acupoint pierced, he was punished to stand for four hours.

"A healer's heart is benevolent," his father would always say while grinding medicinal ingredients.

"But benevolence without medical skill is just a quack harming people."

When Sun Yan was fourteen, a plague swept through Huaishu Town.

His father treated patients day and night without rest, eventually contracting the disease himself.

Before he died, he pressed a yellowed medical book into Sun Yan's hand:

"Yan'er, this is everything I have learned in my life... but it is not enough."

He gripped Sun Yan's hand tightly, his eyes wide:

"Legend says there is a 'Medicine King Valley' in the south. There, they have things that can bring the dead back to life... bring the dead back to..."

Before he could finish, his hand went limp.

Sun Yan knelt by the bed, clutching the medical book until his knuckles turned white.

He did not cry.

He simply tucked the medical book close to his body, shouldered his pack, and headed south.

This journey lasted ten years.

Nineteen years old, the border.

Sun Yan served as a military doctor in the army camp and witnessed the most tragic battlefields.

Arrows fell like rain, and blade-light flashed like snow.

He crouched in a tent, using red-hot iron pincers to remove arrowheads for soldiers, surrounded by a chorus of screams.

A young soldier was carried in, his abdomen pierced through, his intestines spilling out.

The soldier grabbed his hand, eyes bulging:

"Doctor... I... I don't want to die... my mother is still waiting for me at home..."

Sun Yan lowered his head and continued stitching.

He knew the soldier wouldn't survive the night.

But he stitched anyway.

Twenty-five years old, Qingxi Village.

While staying in this remote mountain village, Sun Yan discovered that the villagers were suffering from a strange illness: weakness in the limbs and gradual wasting away until they could no longer walk.

He spent half a month investigating and finally found the cause—a patch of Bone-Eroding Grass was growing next to the village well. The rotting roots seeped into the well water, and long-term consumption led to poisoning.

He was preparing to organize the villagers to fill the well and clear the source, but the village was targeted by a group of bandits.

"Hand over the food and the women!"

The bandit leader sat on a horse, brandishing a large blade. "Or I'll slaughter your whole village!"

The villagers were terrified, trembling in fear.

Sun Yan stepped forward.

"Brave heroes," he said, cupping his fists.

"This village is currently suffering from a plague. The food and water are contaminated. You'd be better off going to Zhang Family Manor twenty miles away."

"Bullshit!"

The bandit leader lashed a whip across his face, tearing his skin open.

"I think you're just tired of living!"

A flash of a blade.

Sun Yan felt a chill in his abdomen as warm liquid gushed out.

He looked down and saw his own blood staining the dirt.

"Doctor Sun!"

The villagers' cries of alarm grew more distant.

The moment he fell, Sun Yan felt no fear; instead, he felt a strange sense of relief.

He remembered his father gripping his hand on his deathbed, saying "Medicine King Valley has the art of bringing the dead back to life."

He wanted to say: Father, I searched for ten years and never found it.

But when he spoke, it became:

"The... the well water... don't drink it... remember to fill the well..."

Then, everything went black.

[Simulation Ended]

[Life Summary: Sun Yan, lived to twenty-five, skilled in medicine, died protecting villagers.]

[Evaluation: B+]

[Inheritable Options:]

Li Changsheng bolted upright in bed, gasping for air.

The sharp pain in his abdomen still lingered in his nerves. He reflexively looked down; it was intact, without even a scar.

Cold sweat soaked his undershirt.

"It was just a simulation... just a simulation..."

He took a long time to steady his breathing before checking the System panel.

Three inheritable options:

[1. Sun Yan's Medical Legacy (Includes: eighteen internal injury conditioning formulas, diagnosis and treatment experience for thirty-two common ailments, acupuncture techniques)]

Li Changsheng's heart skipped a beat.

Internal injury conditioning formulas?

What did he lack most right now? A way to repair his Meridians!

[2. Bone-Eroding Grass Toxicity Analysis (Special knowledge: ability to identify and utilize this chronic poisonous grass for offense or self-defense)]

This was also good. If he encountered an opponent he couldn't defeat in the future, poisoning would be a viable method.

[3. Ten Years of Travel Experiences (Includes: regional geography, customs, herb distribution, and... a clue to a suspected 'Medicine King Valley')]

Li Changsheng was stunned.

Medicine King Valley?

The one Sun Yan searched for ten years and never found?

He stared intently at the words in the parentheses, his fingers trembling slightly.

Three options.

One was the key to solving his current predicament (repairing Meridians).

One was a means for future survival (using poison).

One was a clue to a hidden plot (Medicine King Valley).

Which one to choose?

Li Changsheng stared at the three options, hesitating for only three seconds.

"Select 1."

The moment the words left his mouth, a massive amount of knowledge flooded into his mind like a bursting dam.

The properties and channel tropism of over three hundred herbs, the acupuncture contraindications for seventy-two vital Acupoints, the floating, sinking, slow, and rapid qualities of twenty-eight types of pulses, the roles of sovereign, minister, assistant, and envoy in thirty-six internal injury formulas...

This knowledge wasn't just rote-memorized dogma; it was as if he had personally gathered the herbs, performed the acupuncture, and felt the pulses himself—it became muscle memory.

Even more strangely, his hands began to tremble slightly.

A peculiar burning sensation came from the pads of his index and middle fingers—the "needle sensation" known only to those who have handled needles for many years.

Li Changsheng looked down at his hands and suddenly gave a small smile.

"Sun Yan, I accept your medical skills."

He closed his eyes and, according to the newly acquired medical principles, began to inspect his own body internally.

His consciousness sank into his body, and he "saw" his ruined Meridians.

Of the twelve primary Meridians, six were broken.

The most severe were the Triple Burner Channel of Hand-Shaoyang and the Liver Channel of Foot-Jueyin. They were covered in web-like cracks; when True Qi flowed there, it was like water pouring into a sieve, leaking away completely.
