The Purple Cloud Divine Thunder ranks second among the Twelve Divine Abilities of Mingcang Sect, only behind the Dragon Coiled Great Thunder Seal. However, Zhang Yan previously discovered in his magical duel with someone that the power of this ability wasn’t very formidable, at least when compared to the Nine Mountains Clear Sound and Bright Three Yang Qi, it still falls short.

Although this technique has some effectiveness in restraining evil demons, compared to its grand reputation, it seems somewhat undeserving.

In the past, when he used this technique, he relied on his superior mana to gather dozens or even hundreds of divine thunder strikes, forcing the opponent to temporarily retreat. But if someone else were to use it, it would be a waste of mana.

At that time, he felt this divine ability couldn’t be so simple and must have unknown aspects yet to be discovered. It wasn’t until receiving the sect leader’s bestowed spell that his conjectures were validated. 𝒻𝑟ℯℯ𝑤𝑒𝑏𝑛𝘰𝓋𝑒𝓁.𝒸𝑜𝘮

His previous practice was merely a glimpse into its foundations, and only upon learning the technique of application could he genuinely master the spell completely.

The "Purple Cloud Divine Thunder Net" can extend thunder, weaving an electrifying net. Once a cultivator is trapped within, they can be refined by the power of thunder.

Zhang Yan sighed; if he had mastered this divine ability at the Sword Fighting Conference, it would have offered him an extra means to restrain Feng Haiyang.

However, upon reflection, if not for his significant contributions to the sect, he wouldn’t have obtained this spell. Moreover, the power of this technique is immense, requiring diligent cultivation to reach a level where it can be wielded with ease; achieving Great Success is unknown how many years away.

He shook his head, discarding all stray thoughts and settled his mind, slowly moving the Qi Mechanism according to the method outlined in the Qi Technique.

Back mountain of E Mountain Sect, Thousand Cave Rock.

Yong Fu sat upon the Dharma Platform and asked, "Disciple, have all the sects received the personal correspondences?"

Bai Jiyin replied, "Among thirty-eight sects and noble families, except for Longxiang Sect and the Shi Family, whose leaders are absent from the sect, the others verbally promised to come and witness the fighting on that day."

Yong Fu acknowledged, "The Shi Family’s clan leader left for the Chu Kingdom last month; I am aware of this. I hope he returns by the time of the fighting. As for Longxiang Sect..." He paused, "let them be."

Bai Jiyin nodded in agreement. E Mountain Sect has managed the immortal city for over two hundred years, thanks to Yong Fu’s skills. Since the rules are not strict, the sects within Divine House Mountain have all submitted.

Only Longxiang Sect is different. This sect arrived a hundred years ago, with some mysterious backing. Yong Fu had repeatedly reminded them not to offend, though he avoided the topic when asked.

Currently in a bright mood, Yong Fu said, "In about half a month, I’ll be able to master the Sacrificial Refinement of that Dharma Treasure. During my absence, you shall arrange the fighting affairs. Do not neglect the sect leaders; ensure they’re well accommodated."

Bai Jiyin responded, "Rest assured, I understand, Master."

Yong Fu nodded. Glancing up at the sky, he remarked, "The time is near; you should leave first to avoid injury during my refinement of the Purple Tribulation Fruit."

Bai Jiyin bowed and departed from the Cave Mansion.

After sitting for a while, Yong Fu activated his mana to seal the cave door, then took out a wholly emerald Pearl Fruit, offered it up into the air, and released an Inner Breath to support it. Meanwhile, the Gang Cloud above continuously swirled, releasing bolts of Gang Thunder, crackling and striking the Jade Pearl.

As time passed, the Pearl’s color shifted from green to red. Inside the cave, it first grew chillingly cold, instantly frosting over, followed by intense heat enough to vaporize a cup of water in moments. After nine cycles, the cave’s prohibition couldn’t hold, emitting explosive sounds; if continued like this, the Cave Mansion might collapse.

Soon, Yong Fu stopped the actions, left the cave door, and moved to another nearby cave to restart the process, continuing as before, swapping caves once the prohibition showed signs of collapse.

After more than twenty days of Sacrificial Refinement, shifting through over thirty caves, only a grain-sized speck of the Pearl Fruit remained.

Sensing the timing was just about right, he ceased his Mysterious Skill, slowly absorbing the Pearl into his abdomen. After grinding it down for three-quarters of an hour, he exhaled a long breath of turbid Qi. He then stood up, murmuring to himself, "Finally achieved Great Success. With this Water and Fire Tribulation Power, even if Zhang Daoist really has Second Realm cultivation, I can engage him in battle."
