The Secret Way of Immortality

Ren Qing had previously reviewed the records of two spells, but the Jailer Hall's history had no similar variation branch related to longevity.

He felt a little regretful about this, but after all, extending lifespan was as difficult as ascending to heaven.

Ren Qing had come into contact with hundreds of spells, but very few truly involved lifespan, and they all had limitations.

He understood this in his heart, but after all, the Ghost Shadow could be carried into the Eternal Life Forbidden Zone, and the variation branch could also increase his means of self-preservation.

Ren Qing's lifespan was already three hundred years, and the variation branches of the two spells were more than enough.

However, he could clearly feel that with each century that passed, the lifespan extension efficiency of the Dream Market decreased slightly.

He suppressed the distracting thoughts in his heart and then stared at the human skin book's mutated tree.

The mutated tree was in the shape of a human hand, with branches covered with seedlings of various sizes.

He had mastered the human skin book for several years, but he had never thought about variation after advancing to the Ghost Envoy Realm, and he rarely took the initiative to cultivate.

Ren Qing closed his eyes to rest for a moment, then used his consciousness to touch the seedlings. When the information of the variation branch came into view, the strange object began to move.

His entire body's skin became active, and then began to squirm like a liquid.

This indicated that the accumulation of the Substitute Ghost Skin in the Ghost Envoy Realm had reached its limit. Even if he had not yet consumed his lifespan, the strange object was trying to advance on its own.

If he did not choose a suitable variation branch before the advancement, the Substitute Ghost Skin would randomly complete a variation.

Fortunately, Ren Qing was prepared.

The strange object of the Ice Crystal Method, "Mind-Storing Spirit Crystal", was released from the Everlasting Prison.

A crystal shimmering with colorful light formed on Ren Qing's head. It should have transformed into a crystal giant, but it did not further mutate.

What he wanted was the absolutely calm state of thinking provided by the Mind-Storing Spirit Crystal, so as to quickly browse all the variation branch routes.

He scanned through various variation branches with incredible speed.

His crystallized brain was like a supercomputer, mechanically processing information.

The Ice Crystal Method was even more terrifying than imagined.

Ren Qing only spent half a minute browsing through the variation branches, and even took the time to make a simple classification of the abilities.

The vast majority of the variation branches focused on strengthening the skin, such as [Cowhide], [Fleshless], [Strange Skin], and so on.

[Cowhide]: Makes the Substitute Ghost Skin extremely tough, easily able to withstand sharp weapons, and able to recover quickly.

[Fleshless]: The skin gradually thickens, beginning to cannibalize its own flesh and internal organs.

[Strange Skin]: The human skin completely separates from the main body, able to detach from the body for a short time and attach to the surface of other creatures.

There were also variation branches that enhanced the substitute ability, such as [Shedding Skin] and [Sewing].

[Shedding Skin]: Sheds skin every hundred days, during which it is relatively weak, but can use the substitute human skin to resist fatal injuries.

[Sewing]: Can sew other people's skin onto itself, can remotely transfer injuries, but will cause the skin to rot.

Unfortunately, there were no abilities related to extending lifespan.

However, Ren Qing had no negative emotions. The Mind-Storing Spirit Crystal allowed him to instinctively choose a variation branch.

One variation branch was called [Mimic Skin].

[Mimic Skin]: The skin can defend against the erosion of alien auras and gradually develop resistance.

According to Ren Qing's understanding, the human skin book was a spell that allowed cultivators to adapt to various harsh environments, and Mimic Skin could further strengthen the spell's characteristics.

It indirectly enhanced the potential of the Substitute Ghost Skin.

For the next variation branch, Ren Qing also chose very decisively. He would have hesitated for a long time if it were during normal times.

[Living Skin]: Excess fat and essence will be stored in the skin, and can be used to replenish the body's deficiencies at any time.

Ren Qing narrowed his eyes. The Substitute Ghost Skin's three variations were completed.

[Eating Skin]: The pores on the skin can replace the mouth for breathing and absorbing nutrients.

The Eating Skin variation allowed the skin to replace some of the functions of the internal organs. Combined with the Living Skin variation, the vitality was as tenacious as a cockroach.

If the human skin book could be applied to the clone body, it could also reduce the symptoms of internal organ failure and reduce the rate of lifespan consumption.

The Mind-Storing Spirit Crystal was once again imprisoned in the Everlasting Prison.

Ren Qing's skin all over his body felt a burst of tingling, and then his pores opened, suddenly giving him a special feeling of enlightenment.

He quickly poured peach wine on his body.

The wine was quickly absorbed after coming into contact with the skin.

Ren Qing checked his lifespan and found that it had indeed increased very slightly.

He immediately showed a look of joy. The clone's body was inevitably withering due to the disease, but if he could use his skin to absorb peach wine to extend his lifespan, the trouble would naturally be much less.

However, the clone's body was after all generated from the Eternal Life Forbidden Zone, and Ren Qing was not sure whether he could interfere, but it was always a method.

After the human skin book reached the Substitute Ghost Skin's three variations, information about the Underworld Official Realm also emerged from the mutated tree.

The Underworld Official Realm was called "Gods Under the Skin".

Gods Under the Skin meant that the cultivator's skin would be strengthened every moment, which was simply a good material for refining strange fetal devices.

Ren Qing rested for half a day, then looked at the Armor-Piercing Art.

Even the human skin book could not extend lifespan, and the back-attached bone weapon was even less likely to do so.

However, Ren Qing still used the calm state brought about by the Mind-Storing Spirit Crystal ability to quickly browse through the Armor-Piercing Art's mutated tree, with the idea that there might be something missing.

But the result was somewhat unexpected.

The mutated tree of the back-attached bone weapon, from the roots to the seedlings on the branches, appeared relatively ordinary and related to the natal magic weapon.

Like [Spine Connection]: Connects the dragon-snake spine to the spine of a living being, and can use the natal magic weapon to forcibly control the body's movements.

Or [Regeneration]: Can quickly recover after the spine in the body is damaged.

But Ren Qing noticed that the newly grown seedlings at the top of the mutated tree were somewhat different, actually showing a dark color.

He originally thought that it was a special variation branch that appeared after the main and secondary spells were related, and the Ghost Shadow indirectly affected the Armor-Piercing Art.

But what he did not expect was that this variation branch was closely related to the Netherworld Art.

The spirit root and immortal bone of the Netherworld Art were integrated into the spine, and the essence of the Armor-Piercing Art was already different, tainted with the characteristics of the Heavenly Dao Art.

This led to the change in the variation branch.

[Insect Bone]: The bone's enhancement of strength is greatly increased.

[Insect Armor]: The bones transform into external bone armor and grow insect wings.

Most ⊥ new ⊥ small ⊥ say ⊥ in ⊥ six ⊥ 9 ⊥⊥ book ⊥⊥ bar ⊥⊥ first ⊥ hair!

[Compound Eyes]: The eyes turn into insect compound eyes.

Ren Qing was not interested in insectification. Even if it seemed good, it was after all mutating in the direction of the Heavenly Dao Insect. Who knew if there were any drawbacks.

However, there was also a variation branch hidden within that could extend the lifespan of the clone.

[Insect Root]: One's own spirit root becomes a renewable organ. Take a part of it and transform it into an insect root. The spirit root can forcibly control the insect root.

Ren Qing did not hesitate to choose "Insect Root".

For him, the insect root was the opportunity to extend his lifespan, because the insect root was equivalent to the aptitude to cultivate the Heavenly Insect Art.

If Ren Qing's clone could cultivate the Heavenly Insect Art, each advancement could increase his lifespan, from decades to hundreds of years.

The only trouble was Youyuan.

He could only refine magic weapons to store Youyuan, and then let the Ghost Shadow carry them into the forbidden zone.

However, when the clone was strong enough, it could communicate with the Everlasting Prison within the Eternal Life Forbidden Zone, and then Youyuan could be endless.

[Do you want to choose the variation branch "Insect Root"]

Ren Qing immediately carried out the transformation of the insect root. There were some subtle differences in his own spine, like a heart beating from time to time.

He then cast "Insect Root", and suddenly a violent tearing sensation arose in his spine.

Ren Qing could not help but tremble all over, as if he was pulling the spine out of his body alive, and even the strange object itself was somewhat restless.

If it were not for the Ghost Shadow suppressing it, the back-attached bone weapon would probably riot.

After more than half an hour, the insect root was finally conceived. The spine had shrunk a lot and became somewhat listless.

The insect root looked like an ordinary spine on the outside.

As soon as Ren Qing took the insect root to the outside world, the latter took the initiative to absorb the true essence in the air, which was enough to refine a strange fetal device.

However, he was exhausted, and his spine made all parts of his body weak.

Seeing this, Ren Qing spent another fifty years of lifespan to complete the second variation [Regeneration], and then felt better.

Under the influence of the variation regeneration, the spine absorbed the Youyuan in the body, and the aura it emitted recovered at a speed visible to the naked eye.

Ren Qing tried to store the insect root in the Ghost Shadow's body, but something unexpected happened. The two actually merged together.

The insect root seemed to have become the Ghost Shadow's pseudo-spirit root.

The Heavenly Dao Insect secreted dark liquid to nourish the insect root, causing it to regenerate and change.

The insect root had a tendency to ghostify, but it still needed a period of time to nourish it.

As for the third variation, Ren Qing was inspired by the insect root and chose a variation branch that could complement each other, an ability called [Insect Body].

[Insect Body]: The body parasitized by the insect root will gradually mutate into an insect body, becoming more adapted to the true essence, and the aptitude will be correspondingly improved.

After the back-attached bone weapon advances to the Underworld Official Realm, it is called "Immortals in the Bones". There are no specific records in the Jailer Hall, and it is not known what abilities it has.

Ren Qing could not see the effect of the insect body, so he ate some food and closed his eyes to meditate, waiting for the clone's conception and the complete recovery of his spine.

He originally thought that the conception of the clone would be faster, but the insect root only took a dozen days to transform into a half-virtual and half-real Ghost Shadow Insect Root.

Ren Qing's eyebrows flickered with a faint light, and the clone was about to be conceived again, and it would not be long before he could go to the Eternal Life Forbidden Zone again.

He just wanted to take out the insect root to check it out.

But he did not expect that because of the spell association, the Shadowless Ghost also inherited part of the "Insect Body" ability.

However, the form of expression was slightly different.

The insect root did not turn into the shape of a spine after leaving the Ghost Shadow, but became a half-meter-long black worm, and then re-integrated into the Ghost Shadow.

Ren Qing found that the black worm was the worm formed by Han Li and others practicing the Heavenly Insect Art, and it had more or less certain growth potential.

He could directly bestow the insect root to mortals, giving them the aptitude to cultivate the Heavenly Insect Art.

Most importantly, the black worm does not occupy the Ghost Shadow's volume, can be endlessly conceived, and can even summon a large number of them to injure the enemy.

The black worm can improve the clone's body, and Ren Qing is confident that he can live a few more years.

Of course, the clone does not need to live too long. After all, the Eternal Life Forbidden Zone is for obtaining temporary lifespan. As long as he conceives a clone every once in a while, it is equivalent to having another channel for extending lifespan.

After getting on the right track, Ren Qing does not even need to pay too much attention to the Eternal Life Forbidden Zone.

Throw the clone into the Eternal Life Forbidden Zone and ignore the development of things inside. In addition to extending lifespan, there may be other gains.

For example, the "Eternal Life Art"?

There are more chapters, wait a moment.
