Cultivation is just so scientific!

He redirected his gaze to Li Yuanba, especially at Li Yuanba's Supreme Yang Sword Intent.

With a hint of amazement in his eyes, the content he discussed today was already embodied within the Supreme Yang Sword Intent, and Li Yuanba's talent in sword cultivation impressed him once again.

He felt that Li Yuanba's comprehension of Sword Intent had long surpassed the Golden Core Realm, reaching the Nascent Soul Early Stage level.

However, the Golden Core bottleneck blocked Li Yuanba's Sword Intent from truly achieving the Nascent Soul Early Stage. Master Uncle Wu's explanation was addressing Li Yuanba's foundation, which had nothing to do with the level of Sword Intent.

Initially, Master Uncle Wu intended to instruct Li Yuanba for three to five days, but now he's decided to extend the time a bit longer.

In the days that followed, within this seemingly ordinary cave dwelling, Master Uncle Wu spent half a day each day explaining the pre-Nascent Soul chapter of the 'Sky-Surging Sword Intent Technique' to Li Yuanba.

Starting from the Qi Refinement chapter, he meticulously explained bit by bit.

With Master Uncle Wu's Nascent Soul Middle Stage level, which was even more insightful than Jian Wuwei, he essentially reconstructed Li Yuanba's core foundation in the Sword Dao.

So fifteen days passed, and during this time, no cultivators came to disturb them.

The situation of this temporary cave dwelling had long been spread; with a Nascent Soul Middle Stage Sword Cultivator from the Sword Intent Chongxiao Pavilion inside, no cultivators dared to provoke them.

Not to mention provoking, even the nearby area had been marked as a forbidden zone by the surrounding cultivators.

On this day, after explaining the last of the Golden Core chapter of 'Sky-Surging Sword Intent Technique' in the morning, Li Yuanba sat cross-legged on the mat, starting to connect with IBMz15, analyzing and sorting today's gains in his mind.

Li Yuanba had long abandoned his Body Refining Technique 'Fiery Sun Jade Body Technique' over these days.

After discovering that Li Yuanba had been cultivating the Body Refining Technique 'Fiery Sun Jade Body Technique', Master Uncle Wu criticized him since 'Sky-Surging Sword Intent Technique' itself includes a segment of Body Refining Techniques.

Neither Li Yuanba nor Jian Wuwei noticed this segment, but it's not their fault. The content of 'Sky-Surging Sword Intent Technique' is extremely complex and vast, featuring many cultivation techniques alongside numerous sword dao secret techniques.

When practicing 'Sky-Surging Sword Intent Technique', cultivators generally focus on the Sword Cultivation Technique and choose suitable sword dao secret techniques to practice.

And that segment of Body Refining Technique had no indication; before Master Uncle Wu explained, he didn't even know it was a Body Refining Technique.

Currently, Li Yuanba is practicing the Body Refining Technique known as 'Sword Body', and he had no trouble in converting the Body Refinement of 'Fiery Sun Jade Body Technique' to 'Sword Body', mainly because a Nascent Soul Middle Stage Sword Cultivator was beside him, and from the same sect practicing 'Sky-Surging Sword Intent Technique'.

Master Uncle Wu had also practiced 'Sword Body', and with the help of IBMz15, Li Yuanba's transition process was exceedingly smooth.

Master Uncle Wu particularly assisted Li Yuanba in cultivating 'Sword Body' with his own Sword Intent, enabling Li Yuanba not to waste even a bit of Body Refining energy, elevating his 'Sword Body' to the realm of Body Refining Grand Elder.

Li Yuanba was connected with IBMz15 when suddenly his mind entirely refocused, and all the sword dao knowledge gained from Master Uncle Wu over these ten-plus days, combined with his previous cultivation perceptions, all flashed vividly in his mind.

Master Uncle Wu sensed the strange aura rising from Li Yuanba, and a smile appeared on his face.

This peculiar aura represented that Li Yuanba had found his opportunity for advancement; his journey outside was precisely to find the opportunity to ascend to the Nascent Soul.

Unexpectedly, encountering Master Uncle Wu not only solidified his foundation but also serendipitously helped him find the opportunity for his advancement to the Nascent Soul.

The continuously flashing sword dao knowledge made Li Yuanba suddenly feel enlightened regarding 'Sky-Surging Sword Intent Technique', and the fog blocking his way vanished, including the Nascent Soul bottleneck, which had previously felt like a mountain.

No need to take any Spirit Pills for promotion assistance; he did not even consider these matters. His whole being was immersed in a state of clarity in his Dao Heart.

He smiled faintly; his exquisite face, with that smile, was like a hundred flowers blooming, yet contained a sublimation of the Dao.

"This kid is just too handsome!" Master Uncle Wu muttered to himself while taking out a vein-locking plate and placing it beside Li Yuanba.

Inside the vein-locking plate was a Nascent Soul Mid-stage Spiritual Vein. As for its origin, it's needless to say it was one of Master Uncle Wu's war trophies.

He had no reluctance as he pointed at the vein-locking plate, causing the Nascent Soul Mid-stage Spiritual Vein inside to erupt, unleashing an immense amount of Spiritual Energy from the vein-locking plate.

If any other cultivators witnessed his maneuver, they might feel heartbroken.

The operation was significantly exhausting the Nascent Soul Mid-stage Spiritual Vein's origin; it was solely to make the vein-locking plate swiftly exhale more Spiritual Energy.

This time, Master Uncle Wu's urging reduced the Nascent Soul Mid-stage Spiritual Vein's lifespan by several hundred years.

But he didn't regret it at all; anyways, these Spiritual Objects could be obtained by raiding hostile forces.

The Spiritual Energy dispersed in space was entirely drawn toward Li Yuanba, with his body voraciously devouring the Spiritual Energy.

Inside his body, the Golden Core was likewise engulfing, not only consuming the Spiritual Energy entering his body but also absorbing his vitality and spirit.

His perfect visage was wasting away visibly, his eyes even turned hollow.

Yet within the content of his Golden Core, a small Nascent Soul was forming, each part of the Nascent Soul absorbing massive Spiritual Energy.

Li Yuanba didn't need to worry about his vitality or spirit; he had practiced Body Refining techniques and reached the realm of Body Refining Grand Elder, which elevated his vitality to an exceedingly high level.

His spirit was not considered the strongest, yet even among the Great Elders, he was viewed as exceptionally strong.

Master Uncle Wu didn't utilize Divine Sense to avoid affecting Li Yuanba's breakthrough process, but his ample experience and protective presence made it unnecessary to fret about unforeseen incidents for Li Yuanba.

He also prepared several Spirit Pills to assist with advancing to Nascent Soul, safeguarding against Li Yuanba being unable to naturally breakthrough.

Naturally, he preferred not to let Li Yuanba use these Spirit Pills circling advancement, because the tribulations during the advancement to Nascent Soul were of immense benefit to Li Yuanba's growth.

Li Yuanba's body looked gaunt, yet within him, a surge of vitality was emerging.

The Golden Core contained a small Nascent Soul with complete limbs and even facial features, and when the Nascent Soul's eyes opened, a flash of brilliance glimmered within.

Having experienced the promotion process of his real body, Li Shiming, Li Yuanba was not unfamiliar with advancing to Nascent Soul Stage.

However, when Li Shiming ascended previously, the difficulty was so great it almost reached the heights of being against the Heaven and Earth rules; yet this time, his advancement resembled that of a normal Great Elder reaching Nascent Soul Stage.

The Nascent Soul was bound by the Golden Core shell and as it extended a hand, a sword of energy appeared within its grasp.

The Nascent Soul swung the sword down, instantly shattering the Golden Core shell.

The method by which the sword cultivation Nascent Soul broke open the Golden Core shell was exceedingly violent, yet aligned with the conduct of a Sword Cultivator.

Within Li Yuanba's Nascent Soul, there were no other runes, only pure cultivation method runes of 'Sky-Surging Sword Intent Technique', and a short sword formed by many cultivation method runes stood upright within the Nascent Soul's body.

This cultivation method rune short sword was essentially a manifestation of Supreme Yang Sword Intent alongside the 'Sky-Surging Sword Intent Technique'.

Li Yuanba didn't require any special adaptation to his Nascent Soul; unlike other Great Elders who needed a period of adaption post-formation, he already knew how to use the Nascent Soul.

The real body Li Shiming had five Nascent Souls, and he only needed to manage one Nascent Soul, making it quite relaxed.

He adeptly operated the Nascent Soul, casting spells, and his previously withered body began to rejuvenate, establishing a complete connection between the Nascent Soul and the body.

Normally, a Spirit Pill would be necessary to restore his body, yet truly mastering the Nascent Soul provided various methods for recovery, not only physically but also spiritually.

Generally, cultivators who had just formed the Nascent Soul couldn't achieve this; proper control over the Nascent Soul takes time, typically several months.
