But “Jade Palace Golden Scripture” and “Heavenly Treasury Purple Ji” are both rather brief when it comes to the subject of magic; they only explain a few extremely powerful techniques for self-defense and disaster aversion, with the rest being glossed over without detailed records. Unlike the “Jiazi Divine Book,” which starts from the basics, these begin at a very advanced level.

From his research, Brian Cooper found several methods to solve his needs. However, he decided to take the harder path and cultivate the fundamentals directly, rather than just practicing an emergency spell—after all, increasing his strength could only be beneficial.

The cultivation level of “Jade Palace Golden Scripture” starts off quite high, but its approach is completely different from Brian Cooper’s previous methods and even conflicts with them, so he had to give it up. “Heavenly Treasury Purple Ji,” on the other hand, complements his cultivation path. It is divided into seven chapters, each recording a cultivation formula for a specific divine ability. The seventh chapter is the Purple Flame Seven Annihilations, in which Brian Cooper has already made some progress. This technique allows him to control the Heavenly Realm’s Purple Pure Doushuai Fire, which can incinerate all things in the world and has supreme power to subdue demons and evil spirits. The other chapters are similarly formidable.

Brian Cooper plans to focus on cultivating the third chapter, “Jade Flesh Immortal Body,” because this immortal technique can address his current needs. The Jade Flesh Immortal Body is the supreme secret of immortal martial arts, capable of forging the practitioner’s body into one of unparalleled strength. Brian Cooper also envies some of its marvelous uses.

In fact, whether it’s immortal martial arts or demonic techniques, both can strengthen the body, granting practitioners a physique far beyond ordinary people, allowing them to unleash their physical potential a thousandfold—lifting mountains, traveling thousands of miles a day, impervious to blades and axes, unscathed by water or fire. The most advanced can even achieve flight and transformation. The Jade Flesh Immortal Body is a top-tier immortal martial art; once mastered, even immortal artifacts and demonic weapons can hardly harm the practitioner, and no divine power or strange technique can do anything against it.

Brian Cooper himself is already a master in this field—lifting Mount Tai and crossing the North Sea, such outrageous feats are barely within his reach. In terms of flight speed, even the fastest modern fighter jets may not surpass him. The Roc Soaring Technique is also a top-tier demonic martial art, not necessarily inferior to the Jade Flesh Immortal Body. But every art has its specialty; for example, the Jade Flesh Immortal Body’s defensive effect is simply incomparable to the Roc Soaring Technique. At the very least, Brian Cooper estimates that if he encounters a magical artifact on the level of the Whirling Light Ruler, the Jade Flesh Immortal Body should ensure his safe escape, sparing him from ending up like a bald roc as he did last time.

Most importantly, once the Jade Flesh Immortal Body is mastered, he can use refined immortal energy to mask his own demonic aura. Brian Cooper is confident that even a demon-revealing mirror might not be able to fully expose his true form. However, the aura of demons and monsters is different from that of humans and cannot be changed; at most, he can conceal it completely, but cannot transform it into human spiritual energy. Once the Jade Flesh Immortal Body is mastered, this problem will no longer exist—protected by immortal energy, no one will ever be able to tell whether his true form is demon or immortal.

While Brian Cooper was studying Daoist arts, he sensed someone coming upstairs, but paid no attention. Although he could gain great benefits from the acquired scriptures, he couldn’t help but feel some resentment. Not to mention the “Jiazi Divine Book,” but if he had cultivated according to the “Jade Palace Golden Scripture” and “Underworld Purple Ji” as recorded, it would have taken only three to five hundred years to reach his current level, or even surpass it. How could Brian Cooper not be angry?

Brian Cooper muttered to himself, full of grievance: “Damn it, I’ve wasted all these years for nothing. If I’d known how big the difference is between having a teacher and not, I would have joined an immortal sect long ago—even if it meant being a lackey! How much effort would that have saved me?”

However, Brian Cooper also knew that some things weren’t worth regretting. Perhaps if he hadn’t secluded himself, he might have already suffered disaster and perished. After all, many cultivators stronger than himself still couldn’t escape calamity when it struck. That person was an example—possessing supreme power, yet still falling victim to a plot and being utterly destroyed.

As his thoughts shifted, something appeared in his hand: the Twelve Banner Sect Escape Talisman.

Brian Cooper set up a Two-Yi Microdust Array within a few square meters around himself for protection and immediately began cultivating. He never cared about others’ affairs more than his own.

After casting the “Fleeting as Flowing Water” spell on himself, Brian Cooper officially began cultivating the Jade Flesh Immortal Body. No matter how advanced Brian Cooper’s Daoist skills were, mastering the Jade Flesh Immortal Body would still take two or three hundred years, so to speed up the process, he had to use this spell. Normally, Brian Cooper would never use this on himself—though demons have long lifespans, there’s no need to shorten his own life, right?

“Fleeting as Flowing Water” can accelerate time within its area of effect. Brian Cooper set the time so that one hundred years would pass in an hour. He estimated that he could complete the cultivation in just a few hours and should be able to finish before dinner.

Brian Cooper examined his body. The first step was to condense his demonic aura and magic power. Using the Heavenly Demon Relic he had cultivated to perfection over more than seven thousand years of arduous practice as the foundation, he had already begun fusing the three newly acquired Heavenly Demon Relics with his primordial spirit over the past few days, turning them into his own cultivation. Now, he would condense his demonic aura and magic power into his primordial spirit, fusing them with the Heavenly Demon Relics for the deepest level of cultivation.
