Legendary Librarian System-Chapter 139: Kidney Shackles

"You've finally at the late stage of the Body Tempering Stage. What do you plan once you reach the peak? Continue creating your personal cultivation technique?"

Meng Ai nodded without hesitation.

She replied, "Yes, Big Brother Liu Wei. Hopefully, the library still has any books I can make a reference to."

Liu Wei nodded. He was about to say something when his eyes widened.

If Meng Ai reached the state where the library at its current level can't keep up, maybe the library can issue her a mission!

Liu Wei never doubted if Meng Ai could not gather a high-grade spirit stone. After all, there was the Silent Weave. If she managed to balance them to the point the library couldn't keep up to provide her knowledge and had no choice but to issue a mission, Liu Wei might be able to get out of his debt.

Liu Wei could only close his eyes and hope that whatever he suddenly thought would occur.

"What are you thinking, Big Brother Liu Wei?"

He shook his head and replied, "Nothing. Continue with your cultivation. I will leave now."

Meng Ai nodded and did not ask any more questions.

She simply watched as Liu Wei proceeded to the Bottleneck Crusher Chambers and asked her puppet worker, "Do you think he will be fine? I mean, he cultivated an unorthodox technique."

The puppet worker instantly replied, "He will be. The librarian is under the greatest care of the library."

Meng Ai's eyes widened and nodded.

…

Liu Wei soon returned to the place where he was overwhelmed with the beast tide. Since he was stronger than his previous visit, the beast tide's quality and quantity increased, too.

In half a day, the Blood Appetite Chain was forged. The Blood consumption became assimilation, and not addiction.

It enabled him to activate the minor level of the essence recycling and blood no longer poisoned his body.

To forge the third chain, Liu Wei returned to the Meditation Garden.

He activated the Manifestation of Stones, constructing a reality filled with Dao of Death and Slaughter.

He was now cultivating within a battlefield. Not far from him were the execution grounds. Corpses littered everywhere.

The place was filled with gore.

Although the stench of blood was lacking since he did not include the Dao of Blood, the place was still enough to forge the third chain.

In a day, death qi was absorbed calmly, without causing him to enter in the frenzy state.

The Death Feast Chain was finally forged. He would now gain power when surrounded by death. The Battlefield Gluttony has now been partially unlocked.

To forge the fourth chain, he had to return to the Bottleneck Crusher Chambers.

This time, Meng Ai saw him again and she tilted her head. 𝘧𝘳𝘦ℯ𝓌𝘦𝒷𝘯𝑜𝑣𝘦𝓁.𝒸𝘰𝓂

Liu Wei merely smiled at her and proceeded to the Bottleneck Crusher Chambers without an intention to chat with her.

Meng Ai asked her puppet worker, "Why is he going in and out of the Bottleneck Crusher Chambers? Did he fail?"

"No, the librarian rarely failed. It simply means he's progressing in his cultivation really well."

"Really?"

"Yes, ma'am."

Meng Ai felt strange but eventually kept the curiosity to herself.

…

Liu Wei, on the other hand, was fighting against the beast tide again. He has to endure near-fatal injuries repeatedly, so he asked the puppet worker to increase the difficulty two times.

He underestimated the difficulty he asked, as he instantly forged the Survival Instinct Chain in less than half an hour.

All his pain and injury triggered a regenerative response instead of panic now. In other words, he gained accelerated healing and his body could now resist collapse during critical wounds.

Once the fourth chain was forged, he did not ask the puppet worker to stop. After all, he could still forge the fifth chain in the same situation.

For the next hour, he absorbed more blood, qi, and vitality than his body could handle.

He refined all excess energy and redirected it into the spleen instead of causing rupture.

Eventually, the Overconsumption Chain was finally forged. It enabled the Overflow Vitality Storage and prevents qi collapse during frenzy.

Liu Wei was beyond exhausted now. Even his accelerated regeneration could barely keep up.

However, he could not stop. He was in the perfect situation.

To forge the sixth chain required him to face a situation where survival seemed impossible.

For the next hour, he really thought he was about to die. The idea of "will to live" ceased to exist.

Eventually, when he almost reached his limit, fighting with half-open eyelids, all his six chains synchronized.

His spleen ascended into Crimson Core Vitality.

He regained twenty percent of his strength, which was more than enough to say to the puppet worker, "End the simulation now."

"Understood."

As soon as the beast tide faded, Liu Wei dropped his but and huffed for breath.

I almost forgot that I won't die. But still, overtime, the idea of death is slowly becoming real.

Liu Wei admired how the Bottleneck Crusher Chamber worked. Although he was aware he wouldn't die and perhaps the simulation would end once he was about to die, the fact that it still continued and he felt like his death was imminent made him forget about it.

While Liu Wei was resting, the System's voice echoed in his head.

[You have finally forged the Spleen Shackles.

The spleen mutates into a Crimson Core of Vitality, endlessly producing life force.

It grants the following:

Blood Rebirth Factor: Minor wounds heal instantly; major injuries regenerate 10x faster; healing speed increases in slaughter-heavy environments.

Essence Recycling: Converts spilled blood (even enemy blood) into qi when absorbed. Corpses and residual vitality fuel regeneration.

Battlefield Gluttony: When surrounded by death, the generation and qi gain becomes stronger. The more carnage, the harder it is to kill him.

Vital Balance: Prevents sudden qi collapse during blood frenzy or backlash. Stops regeneration from overshooting and mutating the body.]

Liu Wei nodded. The very important thing was he gained an enhancement in his regenerative ability. He might not be able to need the Vitality Recovery Pills with it.

Furthermore, with Vital Balance, he did not need to consciously balance the regeneration and blood qi that could possibly collapse inside his body.

Liu Wei admired how perfect the Blood Demonheart Sutra was.

It has been a while since I saw him. He grinned.

…

Liu Wei spent three weeks to forge the Kidney Shackles.

Kidney Shackles were related to lust.

The Blood Demonheart Sutra viewed Lust as the most insidious corruption.

Lust for survival, pleasure, cultivation progress, and immortality itself.

Unchecked, lust burns essence faster than it replenishes, shortening lifespan and causing imbalance.

The Kidney Shackles do not suppress lust.

They anchor it, turning desire into stable essence circulation.

The first chain was called Survival Last Chain.

Liu Wei returned to the Bottleneck Crusher Chamber to experience absolute exhaustion, starvation, and near-death again.

It took him a week. After all, he gained resistance to the same situation again and again. Despite changing the environment from beast tide to endless assassination attempt, Liu Wei's emotion was slowly becoming dull when faced with death.

When the first chain was forged, the instinct to keep living was compressed into the kidneys.

The essence leakage was reduced, fatigue recovery improved, and the kidney began stabilizing Blood Qi.

To forge the second chain was the most interesting. Liu Wei has to set the Bottleneck Crusher Chambers in different scenarios.

First, he was in a place of comfort. That he felt contended and did not want to ascend in his cultivation progress.

The second was pleasure. He dreamed of the most beautiful, seductive girl and resisted the temptation to fall with carnal desire with her.

What awakened him was the System's voice echoing in his head.

[This is exactly how I appear! So you really are lusting for me, huh?]

Hence, he instantly lost interest and easily overcame the trial.

Next was excess consumption to which he easily passed, too.

Hence, he forged the Pleasure Restraint Chain in a single day.

His Blood Qi efficiency increased as a result. Lust no longer causes overconsumption of vitality.

The third chain made him return to the Meditation of Garden.

He underwent the trial of craving for rapid advancement as he confronted it directly.

Liu Wei spent a week in the trial. He had so many reasons that made him crave for rapid advancement, after all. He failed so many times that he already lost count.

In the end, the desire to grow stronger slowed, deepened, and stabilized.

His Qi deviation resistance amplified.

Liu Wei was certain that the probability of the spirit of the Origin Demonheart Body decreased a lot after the forging of the third chain.

The third chain also provides a sustainable-long term cultivation, causing Liu Wei to feel at peace whenever cultivating now.

The fourth chain also has to be cultivated in the Meditation Garden.

He has to balance his masculine and feminine energies, aggression and stillness, and more.

Eventually, his desire was split evenly between yin and yang currents.

His internal balance stabilized and demonic essences no longer overwhelmed his body.

Liu Wei also learned three Dao in the Basic Understanding stage. Dao of Yang, Dao of Yin, and Dao of Yin and Yang.

The fifth chain required him to confront fear of aging, decay, and death.

The wish to live forever was tempered into steady essence conservation.

It took him three days to finally forge the Immortality Craving Chain, gaining lifespan extension manifestation and essence loss per cultivation cycle was minimized.
