The greatest hurdle when practicing the Breathing Fire Technique was the Fire Talisman, condensed from Magical Power, being insufficient to contain the True Fire, causing the True Fire to explode in one’s mouth.

For an ordinary Cultivator, if a Fire Talisman misfired and exploded, the outcome was certain death.

Therefore, when cultivating the Breathing Fire Technique, they would typically spend several years honing their skills in drawing Fire Talismans. Then, they would practice containing Spiritual Fire within talismans using milder Tier One Spiritual Fires.

Only when all preparations were complete would they attempt to contain True Fire within a Fire Talisman.

For some cautious Cultivators, it would take at least twenty to thirty years from first learning the Breathing Fire Technique to actually swallowing the fire.

However, the power of the Breathing Fire Technique was well worth the long years of practice.

In Magical Combat during the Foundation Establishment Stage, True Fire could often be the decisive factor.

After swallowing the Nine Flames True Fire, Yang Jing once again condensed Fire Talismans in his mouth and swallowed the four remaining True Fires together.

After completing the Seed Talisman process, a practitioner of the Breathing Fire Technique no longer needed to swallow fire again. As long as they didn’t deplete all the True Fire within the Fire Talisman at once, they could use their own Magical Power to nurture the True Fire and restore its strength within the talisman.

Yang Jing sensed the True Fire residing within his five organs. With a circulation of the Golden Core Magical Power in his Dantian, the five Fire Talismans instantly flared with brilliance.

His Magical Power had already been used to refine the Five Elements True Fire, so feeding fire with fire resulted in extremely high conversion efficiency.

Yang Jing even had a feeling that he could cultivate this Breathing Fire Technique without even needing to swallow True Fire, and could simply use his own Magical Power instead.

He slowly exhaled. The True Fire was now seeded in his five organs. And since he had already mastered the Five Elements True Thunder to the Peak of Perfection, just like with the Great Five Elements Extinction Divine Light, he now faced no bottlenecks in using the Five Fire Divine Thunder.

The Great Five Elements Divine Light Prohibition was so immensely powerful that it was impossible to practice within the Sect Protection Array, but the Five Fire Divine Thunder didn’t have this drawback. The might of this thunder could be scaled up or down, depending entirely on how much True Fire Yang Jing chose to mobilize.

He tentatively mobilized a wisp of True Fire from his five organs.

The True Fire circulated, reacting within Yang Jing’s body. In the next instant, a brilliantly radiant strand of Five Fire Divine Thunder shot out from his fingertip.

Although the Five Fire Divine Thunder was as thin as a strand of hair, its power was extraordinary.

Yang Jing took a Tier Two Defensive Spiritual Artifact, which he had acquired from some unknown source, out of his Storage Bag and tossed it into the air.

The Five Fire Divine Thunder merely lunged forward. In a flash of lightning and fire, the Defensive Spiritual Artifact was blasted into a cloud of fragments.

’What immense power.’

Yang Jing’s eyelid twitched.

’As expected of a secret Divine Prohibition from the Sect.’ He estimated that if he were to unleash its full power, its might would be comparable to the Great Five Elements Divine Light Prohibition he had witnessed, far surpassing his other techniques.

With a wave of his sleeve, Yang Jing levitated the fragments off the ground.

The fragments, which were refined from a mixture of various Spiritual Golds, bore very obvious signs of high-temperature ablation.

After collecting the fragments, Yang Jing reflected on his unexpectedly smooth progress in cultivating the Five Fire Divine Thunder. It had been practically without any bottlenecks.

’A little preparation goes a long way. Building a solid foundation during the Qi Cultivation and Foundation Establishment stages is really starting to pay dividends now that I’ve reached the Golden Core Realm.’

He put aside these thoughts and began his daily routine: breathing in and out of spiritual energy to convert it into Magical Power.

Although Yang Jing had various methods to increase his Magical Power, he never slacked on his daily cultivation routine.

「A day and a night passed in the blink of an eye.」

Many Ascetic Warriors in the Golden Core Stage would enter seclusion for as little as five or six months, or as long as three or four years at a time.

He slowly opened his eyes and took the Immortal Vine Gourd out from his Storage Bag.

Yang Jing had kept this Gourd sealed in a Jade Box, so its Spiritual Qi was so abundant it seemed as if it had just been plucked from the vine.

Previously, Yang Jing had wanted to imprint the Thunder Prohibition of the Nine Great Celestial Thunders onto this Gourd, refining it into a Celestial Thunder Gourd.

When activated, it would unleash a boundless torrent of Thunder Marsh Divine Sand with unparalleled power.

But after mastering the Forbidden Technique of the Five Fire Divine Thunder, a new idea sparked in Yang Jing’s mind. ’Wouldn’t it be even more powerful if I used this Gourd to unleash the Five Fire Divine Thunder?’

After his Core Formation, Yang Jing had become keenly aware of how slowly his Magical Power increased in the Golden Core Realm.

He had reached Foundation Establishment Perfection by refining Celestial Demons, so with his Magical Power now increasing so slowly in the Golden Core Realm, he naturally turned his thoughts back to the Celestial Demons.

However, without a Demon Realm, capturing Celestial Demons was extremely troublesome. Hunting Demon Cultivators to seize their Celestial Demons was too inefficient. Besides, those who had successfully banished and controlled High Tier Celestial Demons were mostly Golden Core Demon Cultivators themselves. And those Golden Core Demon Cultivators were no pushovers.

Moreover, even a cornered rabbit will bite. If he continuously hunted the Golden Core Cultivators of the Four Demon Sects, he would sooner or later attract the attention of their Nascent Soul Cultivators.

This method was even less efficient than cultivating in seclusion.

Since that path was a dead end, the only option left was to use Demon Summoning to lure Celestial Demons down from the Outer Realm.

This method had the warning of the Nine Yang Sect’s past failure. If not for the huge advantages Yang Jing held over the Nine Yang Sect disciple from back then, he truly wouldn’t dare to try it.

First, his Cultivation had already reached the Golden Core Stage, and he possessed various Divine Techniques that countered Celestial Demons. His Power was far greater than that of the Nine Yang Sect disciple who had attempted Demon Summoning back then.

Second, he had managed to acquire both the Starfall True Demon Array and the Yin Evil Spider Demon Array, which the Eastern Demon Sect had used to summon Celestial Demons and attack the Grand Array. Using these Grand Arrays for Demon Summoning was less likely to attract the attention of Celestial Demons than using the secret Demon Summoning Techniques of the Demon Sects.

Third, Yang Jing planned to perform the Demon Summoning inside his Inner World. Even if the worst-case scenario occurred and he attracted the attention of a Demon Venerable, he could re-enact the Five Elements within his Inner World, reducing it to a state of primordial chaos and expelling the Demon Venerable’s Divine Fragment back to the Outer Realm.
