Amidst such cultivation and deriving spirit patterns, Lu Ye completely lost track of the flow of time, with his mind entirely absorbed by the various combinations of Yin-Yang Dual Origins. He even completely forgot about utilizing the gold-hued spirit fortune stick. Yet, the practice of cultivation did not cease. This state persisted for an unknown duration until Lu Ye suddenly felt his spirit force surging much faster than usual, and at the same time, an intangible shackle seemed to have been broken through, jolting him back to awareness. An aura erupted into a fervent boil, spirit force and blood Qi surged together, and an undefinable comfort permeated from inside to out. He reached Divine Sea Level 9! This had been the bottleneck that troubled countless generations of Nine Provinces cultivators, the highest elevation they could attain for millennia, where many heroes chose death-seeking retreats, hoping for a breakthrough opportunity. Yet ultimately, they all ended in failure. None before this generation realized that a cultivator's realm of cultivation was related to their home world's tier level; if the world's tier wasn't high enough, even with excellent aptitude and cultivation, the dawn of breakthrough remained unreachable. Compared to ancestors of Nine Provinces, this generation of cultivators is extraordinarily fortunate, coincidentally witnessing the elevation of the Nine Provinces World's tier, ensuring future elite cultivators need not worry about being stuck at Divine Sea. But this is an opportunity fraught with risk; connecting with stellar space means Nine Provinces can no longer exist in solitary silence. One day, new enemies and crises may arise, requiring current Nine Provinces cultivators to diligently improve themselves to protect their homeland amidst potential future threats. For cultivators like Lu Ye, Divine Sea Level 9 is merely a new starting point, a horizon reaching into stellar space; only at this level of cultivation can one endeavor into stellar space, albeit just possibly. Though there have been no failures in Divine Sea Level 9 advancement to Constellation thus far, that's because the current elite cultivators of Nine Provinces, without exception, accumulated substantial time in the Level 9 realm, making the success rate naturally high. Moreover, under the previous Nine Provinces environment, those reaching Divine Sea Level 9 were undeniably talented; these elite cultivators just needed an opportunity to soar, which the world's elevation provided. Still, Divine Sea advancing to Constellation is ultimately an elevation of a major domain, lacking certainty of success. Just as with past domain advancements, there was always a risk of failure; while True Lake advancements were manageable given sufficient accumulation, the threshold from True Lake to Divine Sea halted many cultivators. It's foreseeable that, with Nine Provinces cultivation environment changes, advancing to Divine Sea will become easier, while failures in Constellation advancement will inevitably appear. Follow current novels on 𝕟𝕠𝕧𝕖𝕝✶𝕗𝕚𝕣𝕖✶𝕟𝕖𝕥 Ordinary cultivators advancing from Divine Sea Level 8 to Level 9 don't experience much, merely strengthening their foundation and power. But after Lu Ye's advancement to Level 9 here, he clearly felt a mystical force starting to work, gently invigorating his every cell, enlivening his flesh and making him feel comfortably warm. With subtle perception, Lu Ye understood what force was in play. It turned out to be the reward for ascending to the top in the Taichu Realm! This force lay dormant in his flesh prior, expected to activate upon advancing to Constellation; unexpectedly, it began now. This is undoubtedly better, as the period from Divine Sea Level 9 to Constellation requires accumulation; during this time, this mystical force will naturally maximize its effect. He gained clarity that when this gentle force fully integrates with his flesh, it marks the optimal moment for his advancement to Constellation! This process may require a duration. Turning his head, he looked at the rabbit-like Number Nine beside him, "Thanks!" During his absorbed state in deriving spirit patterns, he completely forgot to crush the gold-hued spirit fortune sticks to maintain cultivation, yet his cultivation persisted without interruption due to Number Nine's arrival. Each time a fortune stick's limit approached, it would crush a new one for him, maintaining his state of cultivation. Otherwise, Lu Ye's cultivation might not be severely impacted, but interruptions during derivation would undoubtedly be frustrating. Number Nine opened its eyelids to glance at him, staying silent, a proud expression saying 'What would you do without me'. Lu Ye rose and walked outside the bamboo tower, gently drawing his Boulder Mountain Saber from his waist. With a thought, Sharpness spirit runes were imbued on the saber! However, this time the imbued runes were not the original Sharpness spirit runes but those derived recently. The long derivation bore some fruit at last. Upon imbuing the new Sharpness spirit runes, a faint light flashed on the black Boulder Mountain Saber, exuding an especially sharp feel. Lu Ye swung the saber, moving gracefully as he did when his cultivation was low, each move meticulously executed. On Emerald Bamboo Peak, amidst the shifting figures, the sound of a long blade slicing through the air was continuous and unending. It was only after a long time that Lu Ye slowly sheathed his sword, his brow furrowed. Even though there wasn't an opportunity to engage a formidable foe in a real battle to test the results of his recent deductions, Lu Ye could still feel that the newly derived Sharpness spirit rune was unsatisfactory. Comparatively, the new spirit rune was indeed slightly better than the previous Sharpness spirit rune in terms of effectiveness, but it hadn't reached the expected level! Let alone compared to the blessing empowered by Lü Yingying. Such a spirit rune would provide limited enhancement in a genuine life and death struggle. At the Constellation level, relying on such results to slay enemies would likely require considerable effort. Indeed, deriving a new spirit rune is not that easy. Previously, when the Void spirit rune had been successfully derived, it was because Lu Ye had learned a complete Void spirit rune from a book. His deductions on Void were merely optimizations of the existing details, not a groundbreaking result. But now, when it comes to Sharpness, it's not so straightforward; it's like deriving an entirely new spirit rune. Even with the original Sharpness as a foundation, the difficulty is exceptionally high! Lu Ye felt that even if he continued to laboriously derive further, there would likely be no significant progress. Fundamentally, although he had some accomplishments on the Path of Spirit Runes, he was still young, and over the years, he hadn't spent enough time on it. Most of his time was spent on cultivation and improving his combat skill, treating the Path of Spirit Runes merely as an auxiliary. It seems he's still too reliant on the Talent Tree. Because he can freely use the spirit runes on the Talent Tree, he's lost the interest and motivation to delve into the Path of Spirit Runes. Indeed, learning has no bounds! Especially with the Path of Spirit Runes, which is more theoretical in nature. Without enough time and energy invested in this path, he's only a half-filled water bucket. Fortunately, there's still the mentor! Lu Ye decided to seek guidance from his mentor! Speaking of which, he hadn't visited his mentor since returning, which seemed somewhat inappropriate. But upon arriving at Bright Moon Summit, Lu Ye discovered the once bustling spirit mountaintop was empty, even the doppelganger, Little Butterfly, who was always present, was nowhere to be seen. It seemed no one had been here for quite a long time. Attempting to send a message to his mentor, the message couldn't be delivered, leaving him with no choice but to contact Second Senior Sister for information. Only upon receiving Second Senior Sister's reply did Lu Ye learn that his mentor had already advanced to Constellation, leaving the Nine Provinces over three months ago, and had ventured deep into stellar space! Not only his mentor, Yun Xuechu, but even the sect master had also left! That's why Lu Ye didn't even see the sect master when he returned this time. Currently, only Shui Yuan remains, holding on bitterly, as she cannot leave. If she does, the entire Righteous Blood Sect would truly be without a leader, and the disciples would be left completely unprotected, becoming scattered like loose sand. Of course, it's also because Shui Yuan's cultivation isn't enough. Although she advanced to Divine Sea long ago, her cultivation is still only Divine Sea Level 7 to this day. Lu Ye couldn't help but be a bit stunned; over three months ago, he was competing against prodigies from various domains in the Taichu Realm. Still, it's a good thing, with his mentor and sect master both advancing to Constellation and exploring stellar space together, their dual journey is quite carefree; it's uncertain whether the sect master can help unravel the mentor's inner knot. With his mentor absent, there's no one to offer guidance, Lu Ye considered for a moment and sent a message to Shui Yuan, asking her to help investigate the whereabouts of renowned spirit runes masters still in the Nine Provinces. Since his mentor isn't around, he'll have to seek out other spirit runes masters to discuss and explore; while these masters still in the Nine Provinces may not compare with him in cultivation and strength, Lu Ye wouldn't underestimate them. Given the previous environment, these spirit runes masters had managed to achieve widespread fame, certainly possessing remarkable qualities worthy of Lu Ye's learning. He didn't leave Bright Moon Summit; instead, he delved right in. It's true his mentor has departed, but the books she left behind remain, and Lu Ye decided to thoroughly revisit the Path of Spirit Runes before advancing to Constellation, starting with the mentor's remaining collection of books.
