Dark Wizard: Rise! My undead army!

Looking at the "warning sign" in front of him, Lynn raised an eyebrow and took out the chief badge from his sleeve.

As soon as the badge appeared, the text on the stone tablet lit up, and then the restrictions on the entire fourth floor receded like a tide.

The suspended bookshelves slowly stopped rotating and fell back to the ground.

He then realized that the fourth floor was divided into seven sections.

Each zone is separated by a soul light curtain of a different color, and at the deepest part there is a black door bound by dozens of chains.

Lynn walked towards the first area first.

The words "Forbidden Meditation Method" floated on the light screen.

He passed through the light curtain and saw a dozen rows of black bookshelves appear before him.

Each bookshelf doesn't hold ordinary books, but rather crystals and black stone slabs sealed with souls.

A label was placed in front of the first black stone slab: "All Souls Return to Their Flow".

Lynn scanned it with his analysis and found that it was a meditation method based on devouring soul fragments.

Each time a cultivator absorbs a soul, their spiritual power limit increases by one point.

Theoretically there is no limit, but the more you swallow, the easier it is for your self-awareness to be torn apart by countless fragments of your soul.

Marfa practices this meditation method!

Lynn was somewhat interested in this "meat pigeon" type of meditation method, which claimed that one could become stronger simply by eating.

However, this thing has significant side effects; it pollutes the purity of the soul, making it extremely difficult to advance to the True Spirit realm.

It's not as practical as the "Starry Sky Beast" Devouring Talent, which not only devours your soul but also everything else, turning it into nutrients for advancement.

After discarding it, Lynn continued examining the document.

Next to it, a larger black stone slab was inscribed with "Eternal Silence Sitting Meditation Exercise".

This meditation method does not require the consumption of the soul, but it requires the practitioner to sit in absolute silence for hundreds of years, during which time they cannot speak, think, or have any emotional fluctuations.

Once you enter a meditative state, your mental energy will increase a hundred times faster than normal meditation.

But upon waking, the practitioner will forget who they are.

This meditation method impressed Lynn, who exclaimed, "Wow!"

A wizard's advancement is not just about increasing mental strength; each stage has different thresholds.

Constructing a spiritual core, core energy transformation, condensing a soul vortex, domain rules, creating sacred marks domains, and so on.

You sat in meditation for a hundred years during your apprenticeship, and as a result, your mental strength reached its limit. When you woke up, you were still an apprentice...

It's even quite possible that one's lifespan will end directly during meditation.

This is most suitable for use by wizards at the Saint Mark level or even the True Spirit level in seclusion. They can seclude themselves for hundreds of years at a time, and after waking up, their spiritual power will have increased significantly, and then they can begin to advance to the next level.

Of course, the first thing to do is to solve the problem of memory loss.

However, this is not too difficult for wizards, as they have many ways to leave "memory anchors" or even "backup" memories.

But if the memory is completely lost, the loss would be enormous.

A wizard's most valuable assets are knowledge and understanding of rules. Without these, even if one's mental strength meets the requirements for advancement, there is no hope of advancement.

Lynn continued walking inside.

He saw a meditation method called the "Three Souls Splitting Method," which could divide the soul into three parts, each cultivating a different path, and then reunite them into one.

The losers are utterly destroyed, while the winners are said to possess three lives and be able to control three different paths.

Morpheus's "Substitute Soul" comes from this, but the Substitute Soul is to refine the soul of another person into another life of one's own, and does not have the ability to merge the two after cultivation.

There is also a book called "The Record of Reincarnation and Rebirth," which records how to simulate death and rebirth within one's own spiritual core, thereby repeatedly breaking through bottlenecks.

Each breakthrough results in a significant loss of potential, a decline in the age of the soul, and an irreversible reduction in lifespan.

This method of death reincarnation involves exchanging the future for a breakthrough in the present, which is quite good for some wizards who have no hope of breaking through.

Lynn didn't linger there. He passed through the second light curtain, which read: Forbidden Witchcraft.

This section has more bookshelves and more detailed classifications.

The outermost layer contains forbidden techniques related to the soul.

He casually picked up a piece of blood-red crystal and probed into it.

It contains the "Soul Freezing Technique," which can freeze a person's soul in eternal suffering, from which there is neither dissipation nor release.

Those who fall victim to the spell will remain conscious forever, trapped in their most terrifying memories, unable to escape for eternity.

This would be excellent for tormenting the enemy.

A black stone slab next to it is inscribed with "Conceptual Curse: Stripping Away Existence".

This curse spell can erase the target's "presence" in the world, making everyone forget about him and unable to see him.

Those who are affected by the spell will not die, but their suffering will be far worse than death.

He would walk around in front of familiar people, but no one paid any attention to him, and eventually he suffered a mental breakdown in loneliness.

Lynn put down the stone slab and saw another curse called "Bloodline Soul Chaser: Nine Generations of Annihilation Curse".

The caster can use their own lifespan as a catalyst to curse and kill the target and their nine generations of bloodline across dimensions.

It's no use for the target to escape anywhere, because the curse chases the soul imprint in the bloodline.

Deeper inside, there is a row of witchcraft items sealed in a crystal cabinet.

Lynn glanced at it with his analysis tool and couldn't help but frown.

"The Soul Cannon": Using 9,999 souls as ammunition, it fires a soul shockwave capable of destroying a city with a single strike.

Soul Stitching Technique: Forcibly stitching together multiple souls to create monsters with multiple personalities and talents. These monsters are extremely unstable and may self-destruct at any time.

"The Descent of the Kingdom of Death": This story chronicles how a death beacon is planted at the core of a plane, slowly transforming that plane into a deathly world resembling an eternal graveyard.

This "Death Kingdom Descends" is quite good; it's very suitable for transforming some worlds into the Land of the Dead.

"Island of Death" would be a good fit in Lynn's Stigmata Domain.

It is the world's "sewage outlet" in itself, gathering the world's filth and transforming it into the world of the dead, which can be considered a kind of compatibility.

Finally, Lynn stopped in front of a cabinet that was sealed off by a red light screen. Inside was a piece of black jade with the words "God-Devouring Ritual" engraved on it.

After reading it, Lynn couldn't help but take a deep breath.

The "god" in this god-slaying story is not some local deity, but a great "true spirit"!

The content of this forbidden technique is to forcibly steal the understanding of rules and laws by devouring the soul core of a True Spirit-level being.

As for the success rate...

It's better not to say anything.

The losers will be directly transformed into primordial soul particles.

This witchcraft is too powerful, it's practically a fantasy, probably just an idea with no successful examples.

If there were truly successful cases, those successful individuals or true spirits would not have allowed this forbidden technique to exist in the world; they would have destroyed it long ago.

"As expected of the forbidden book section, there's such outrageous witchcraft here," Lynn muttered.

"It seems that not all of this forbidden knowledge is true; some are just insane ideas, and using them would likely result in certain death..."
