Cultivation is just so scientific!

A year has passed in the blink of an eye, Li Yuanba has ended his closed-door cultivation, his Nascent Soul Realm has stabilized, and the spiritual power within his body has reached the standard that can sustain his Nascent Soul Dharma Form for a period.

For cultivators at the Nascent Soul Early Stage, such a standard means they are ready to venture out into the world.

While cultivating the 'Sky-Surging Sword Intent Technique', the 'Six Yang Spirit Fire' inside his body automatically absorbed spiritual power, reaching the early fourth grade, enough for him to refine spirit pills for the Nascent Soul Middle Late Stage.

He also encountered an awkward issue: his pill furnace was originally a trophy from a battle, a third-grade pill furnace, which no longer suits his current realm.

Moreover, unlike his original body Li Shiming, he lacks the ability to multitask; when cultivating the 'Sky-Surging Sword Intent Technique', he is unable to do anything else simultaneously.

Upon ending closed-door cultivation and stabilizing his realm, he begins the process of enhancing his Lifebound Flying Sword Xingyi.

He takes out the Fourth Grade Earth Fire Plate; although his 'Six Yang Spirit Fire' can be used for artifact refining, with the Fourth Grade Earth Fire Plate, he need not expend spiritual power to maintain the 'Six Yang Spirit Fire' for refining.

Placing the Fourth Grade Earth Fire Plate in front of him, Li Yuanba's Nascent Soul emerges from his body and jumps out from the top of his head.

The small Nascent Soul sits before the Fourth Grade Earth Fire Plate and spits out Xingyi Sword.

Instead of acting immediately, the Nascent Soul connects with IBMz15. IBMz15 had long started analyzing and researching ways to optimize the power of Xingyi Sword during its enhancement.

As a standard sword cultivator, Xingyi Sword perfectly meets the demands of sword cultivators for a lifebound magical treasure.

The strongest feature of Xingyi Sword lies in its ability to enhance a sword cultivator's Sword Intent. Through years of cultivation, the Sword Intent enhancement of Xingyi Sword increased from 135% to 142%.

Even if he wanted to replace his Lifebound Flying Sword, finding one that enhances Sword Intent this much would be difficult.

The biggest weakness of Xingyi Sword is its inferior material, but using artifact refining materials from the Nascent Soul Stage can reshape the sword body, upgrading the material to fourth-grade and remedying its greatest weakness.

Moreover, after reshaping the sword body, not only does it retain the original effect of Xingyi Sword, but it also amplifies the power added from the refining materials.

Li Yuanba receives the message from IBMz15: it's a Xingyi Sword transformation plan meticulously designed using fourth-grade top-tier 'Abyss True Sand'.

The most unique part of the plan is preserving the fundamental rune of Xingyi Sword while allowing for substantial space for enhancement.

Li Yuanba has many ideas regarding Xingyi Sword, and IBMz15 incorporated these ideas into the design.

However, there's a challenge: the design requires the engraving of 5-nanometer runes, which can only be completed by his original body Li Shiming in the chamber space.

Therefore, Li Yuanba can only first modify Xingyi Sword with the fourth-grade top-tier 'Abyss True Sand', reposition the fundamental rune of Xingyi Sword, and leave the vacant portion empty.

In the future, when he reunites with his original body Li Shiming, Li Shiming will engrave miniature runes at the vacant area, pushing Xingyi Sword to the limit that the fourth-grade top-tier 'Abyss True Sand' material can withstand.

Although Li Yuanba needs to use Xingyi Sword for a long time and it's currently a semi-finished product, considering the miniature rune engraving will enhance the magical treasure's power, it is all worthwhile, even though he's separated from Li Shiming by two continents.

If Li Yuanba possessed a fourth-grade Lifebound Artifact Tribulation Flying Sword, he would dominate any Nascent Soul Sword Cultivator in terms of Lifebound Flying Sword.

Li Yuanba's Nascent Soul places Xingyi Sword on the Fourth Grade Earth Fire Plate and then places the fourth-grade top-tier 'Abyss True Sand' beside Xingyi Sword, to be heated together by the fourth-grade earth fire.

The Nascent Soul repeatedly executes spells for enhancement, which are described in the Secret Technique for enhancing Lifebound Flying Sword found in the 'Sky-Surging Sword Intent Technique'.

Waiting until now to operate, and not using the 'Six Yang Spirit Fire', is due to the massive consumption of spiritual power required for this task; he dare not exhaust his spiritual power during the process.

If the enhancement of Xingyi Sword fails, the damage to Xingyi Sword would result in significant losses.

While Lifebound Flying Sword can be replaced, the replacement cost is excessively high, demanding too much time and effort.

Thus, Li Yuanba finishes the closed-door cultivation only to enter another session of enhancing his Lifebound Flying Sword.

This is also the daily life of Nascent Soul Cultivators; whether in cultivation or other tasks, the time required far exceeds that of the Golden Core Stage.

Li Shiming on his side is also in closed-door cultivation, but fortunately, he can divert his attention, so his closed-door cultivation can only be considered partially closed.

After more than a year, the 'Sky-Surging Sword Intent Technique' cultivation method rune short sword inside the chamber space's Gold Thunder Nascent Soul is 99.99% complete.

Through micro-view, ninety divine senses are simultaneously tweaking miniature runes inside the chamber space Gold Thunder Nascent Soul.

For the rune short sword inside his Gold Thunder Nascent Soul, he halted the sacrifice work for those fourth-grade flying swords.

Now so proficient in this task, he has gone from having one divine sense adjusting miniature runes to ninety brains controlling ninety divine senses simultaneously.

Due to this progress, accomplishing such results in just over a year, otherwise it might take a hundred years to reach this step.

"Hoo," Li Shiming exhaled heavily.

Deeply tense, although the lifebound magical treasure IBMz15 conducted multiple simulations for converting the sword intent rune in Gold Thunder Nascent Soul into 'Sky-Surging Sword Intent Technique' cultivation method rune short sword, simulations are simulations; without factual verification, they cannot be entirely precise.
