WTF, The Centuries-Old Ancestor In Our Family Take Concubine Again! - Chapter 75

Chapter 75

Li Su contemplated the Purple Dawn Divine Thunder, which was divided into nine ranks, much like the levels of demonic beasts, each suitable for different realms. A fourth-rank Purple Dawn Divine Thunder could already threaten those in the Nascent Soul stage, but it required a vast amount of thunderstorms to create. A few years of collection time might not be sufficient.

By the way, why didn’t the Master experience a Thunder Tribulation? Li Su wondered. He had read in novels and seen in movies before his reincarnation that cultivators in the Nascent Soul stage usually underwent a Thunder Tribulation. However, the sect leader hadn’t faced one after her breakthrough.

After spending several days at home and making all the necessary arrangements, Li Su strengthened the formations in the Li Clan residence. While at the Flying Immortal Sect, he had also crafted some formation tools. He repaired several flags for the Great Yan Sword Formation. As for the Great Yan Sword itself, Li Su refrained from crafting it. It required scarce materials, and the consumption of those materials was extensive. Li Su didn’t have many of those materials on hand.

The Li Clan didn’t have to worry too much since the Demon Sect wasn’t targeting them, and it was highly unlikely that the Saintess of the Moon Clan knew it was Li Su who had captured her. After Li Su strengthened the family’s formations, their concealment abilities were greatly enhanced. In case of any unexpected events, Li Su could quickly return. The likelihood of anything unexpected happening was low. The Li Clan’s location was in the south, and the Demon Sect’s path to the Li Clan was farther than the Flying Immortal Sect and not in the same direction.

As Li Su prepared to leave, another piece of good news arrived – the number of descendants with spiritual roots had reached 150. This unlocked another reward—a 200-year increase in soul cultivation. After some consideration, Li Su didn’t choose to increase his soul cultivation but instead opted for the experience from manuals. He allocated this 200 years of manual experience to the Purple Dawn Divine Thunder.

While the Purple Dawn Divine Thunder was somewhat profound, it didn’t require as much time to learn as techniques related to alchemy or weapon forging, which were both time-consuming disciplines. The experience gained from studying manuals in alchemy or weapon forging was also useful for the Purple Dawn Divine Thunder. Therefore, Li Su used the 200-year manual experience to learn a significant portion of the Purple Dawn Divine Thunder technique. This efficiency was also related to his current cultivation level. The 200-year manual experience would have been far less effective if he were still in the foundation-building stage.

However, even if Li Su fully mastered the Purple Dawn Divine Thunder, it would be useless without thunderstorms. The key was still in collecting the thunderstorms. After arranging things at home without news from the Demon Sect, Li Su returned to the Flying Immortal Sect. When asked about Thunder Tribulation, he replied, “Thunder Tribulation? Of course, I’ve had it. I was planning to use it when the people from the Demon Sect arrive to deal with them using Thunder Tribulation.”

The sect leader spoke in the back mountains of the Flying Immortal Sect. Li Su understood the situation. The protective array of the Flying Immortal Sect had been fully activated, effectively creating a small world within it. The sect leader was now isolated within this world.

From Li Su’s perspective, while this protective array wasn’t exceptionally high, it was exceptionally well-developed, having been refined for hundreds of years. It had some formidable qualities. However, the sect leader couldn’t remain inside it indefinitely. If she continued to postpone her Thunder Tribulation, as her cultivation increased, the Thunder Tribulation’s power and danger would grow exponentially.

Li Su was surprised to learn that the sect leader had plans to use her own Thunder Tribulation to deal with the demonic cultivators from the Demon Sect. While it was indeed a unique approach, it was not without risk. “Master, there’s no need for that. I would like to utilize your Thunder Tribulation to refine a special treasure,” Li Su proposed.

Li Su explained the concept of the Purple Dawn Divine Thunder to the sect leader, who initially found the idea of using Thunder Tribulation to refine it somewhat risky. However, she decided to cooperate with Li Su.

“Boom!”

Underneath Mount Mangcang, thousands of miles from any signs of civilization, the sky crackled and thundered. Even the surrounding demonic beasts kept their distance. Though fierce, they weren’t foolish enough to approach when a Golden Elixir cultivator was undergoing a Thunder Tribulation.

The sky was filled with menacing black clouds, creating a sense of impending doom. “Li Su, it’s coming. Are you prepared?” the sect leader’s voice echoed. “Ready!” Li Su clapped his hands. Despite his nightly activities, he still made significant progress on his main tasks.

Li Su wasn’t just idly wasting his time. He refined numerous thunder-attracting artifacts and even set up a special Thunder Attraction Formation, a technique recorded in the secret manuals. This formation improved the collection of thunderstorms, allowing him to draw the thunder directly to his location. Once gathered, Li Su could use them to craft the Purple Dawn Divine Thunder in one go.

“Boom!”

The first Thunder Tribulation had arrived. “Wow!” Li Su exclaimed, looking at the massive thunderbolts. It wasn’t just one. As one fell, more thunderbolts followed, pouring down in rapid succession. These thunderbolts were far more formidable than the lightning during a typical thunderstorm. Even the weaker ones posed a significant threat to Qi refining cultivators.

The power of these thunderbolts was such that even a Golden Elixir cultivator would be severely injured if struck by one. The sect leader had already moved forward, channeling her true essence through the Flying Immortal Sword to disperse the successive Thunder Tribulations. As each thunderbolt was dispersed, its energy scattered and was collected by Li Su’s artifacts and formation.

While Li Su intended to use the sect leader’s Thunder Tribulation, he had no intention of confronting the tribulation head-on. Instead, he chose to stay below and collect the thunderbolts using his formations and artifacts. This way, he wouldn’t interfere with the sect leader’s tribulation process and could efficiently gather the necessary thunderstorms. Interfering with the tribulation might amplify its power manifold, which could endanger the sect leader.

The sect leader was well-prepared for this Thunder Tribulation and had the assistance of top-grade spiritual weapons, making it a manageable challenge for her. Thunder Tribulations were both trials and tests of strength.

Li Su continued his work below, compressing the gathered thunderbolts and placing them into a special large cauldron. “Boom, boom, boom!”

The Thunder Tribulation intensified. Even the fierce demonic beasts on Mountain Mangkang retreated farther, trembling in fear of the Thunder Tribulation, which was at the Golden Elixir stage.

After an hour, the sect leader let out a sigh of relief, thinking it was almost over. However, just as she relaxed, a fearsome bolt of thunder struck from the sky. “What? Another one!”

The Sect Leader’s eyes widened, quickly attempting to respond, but this time, the power of the tribulation was significantly greater, and despite her efforts, she couldn’t fully defend against it. “Master, continue!” Li Su urged her.
