Cultivation is just so scientific!

The greatest gain Li Shiming received from Duan Zhen, the Nascent Soul Middle Stage Practitioner of the Sun Concealing Sect, was the 'False Resentment Netherworld Technique', a transcription of the 'False Resentment Netherworld Technique'.

Li Shiming had been pondering where to obtain the 'False Resentment Netherworld Technique', and Duan Zhen delivered it to him.

This 'False Resentment Netherworld Technique' was prepared for the Golden Corpse Black Shield. At the level of the Golden Corpse, it could already cultivate techniques autonomously.

He first used his lifebound treasure IBMz15 to analyze and study the content of the 'False Resentment Netherworld Technique', then after thoroughly understanding it and including extensive explanations, he transmitted the cultivation technique content to the Golden Corpse Black Shield.

With this cultivation technique content, the Golden Corpse Black Shield began cultivating the 'False Resentment Netherworld Technique'.

It adapted very quickly, mainly because its previous form had already cultivated the 'False Resentment Netherworld Technique', but Li Shiming did not have the technique; hence, after bonding with the Golden Corpse Black Shield, the conscious Golden Corpse Black Shield couldn't independently cultivate the 'False Resentment Netherworld Technique'.

The 'Illusion Resentment Demon Sword' in the Golden Corpse Black Shield's hands had a complementary effect when cultivating the 'False Resentment Netherworld Technique', which surprised Li Shiming.

He wasn't aware of the value of the 'Illusion Resentment Demon Sword'; otherwise, why would Duan Zhen use most of his resources for the 'Illusion Resentment Demon Sword'?

Li Shiming remembered a critical matter from this outing; he and his avatar Li Yuanba shared a telepathic connection, thus naturally being aware of Li Yuanba's situation. There was no need to rush with Li Yuanba; he needed to first complete the final step of the 'Traceless Illusion Gold' sword blank.

He planned to refine the flying sword made from the 'Traceless Illusion Gold' sword blank into his lifebound treasure.

After all, he was considered a Sword Cultivator, and how could a Sword Cultivator be valid without a lifebound flying sword?

He had five Nascent Souls, two of which already had lifebound treasures, leaving three vacancies.

The speed of 'Chichi Tianya' was extremely fast, and soon he found a place some distance away from various cultivation forces.

In the machine room space, Li Shiming used tactile engraving on the 'Traceless Illusion Gold' sword blank to complete the final step.

He took the 'Traceless Illusion Gold' sword blank from the machine room space. Since he was the creator of the 'Traceless Illusion Gold' sword blank, upon completing the final step, he established a spiritual connection with this flying sword.

Without the need for touch, he could sense the flying sword's presence through divine sense.

The flying sword hovered in front of him; the 'Heavenly Thunder Sword Intent' within his five Nascent Souls continually communicated with the flying sword before him.

Even though Li Shiming did not cultivate the top Sword Cultivation Technique 'Sky-Surging Sword Intent Technique', his avatar, Li Yuanba, had, so he possessed all insights from cultivating the 'Sky-Surging Sword Intent Technique'.

However, Li Yuanba was only at the late-stage Golden Core cultivation, so his insights into the 'Sky-Surging Sword Intent Technique' only reached the late-stage Golden Core.

Were it not for the unique opportunity of his 'Heavenly Thunder Sword Intent', which absorbed the might of heavenly thunder multiple times, its sword intent wouldn't have the current power.

The power of his 'Heavenly Thunder Sword Intent', in terms of mere presence, was at the level of the Nascent Soul Early Stage Peak.

In this way, he compensated for the deficiencies in his cultivation technique. With the comprehension of the 'Heavenly Thunder Sword Intent' and his understanding of sword cultivation, Dao Rhymes began appearing on the flying sword.

With a slight movement of his mind, Li Shiming connected with his avatar Li Yuanba, who joined in the interaction with the flying sword. He also instructed his lifebound treasure IBMz15 to bring forth all the research materials on sword cultivation over the years.

He had no choice; his foundation in sword cultivation was lacking. Although he had the most advanced sword cultivation techniques, his primary focus was on the Five Elements Skills, complemented by Thunder Skill. Were it not for the sword intent rune nurtured within his Nascent Soul, he wouldn't even lightly touch upon sword cultivation.

Vast amounts of sword cultivation knowledge continually accumulated toward the flying sword, and one by one, Dao Rhymes appeared on it.

One, two, three, all the way to six, before it stopped.

Six Dao Rhymes, with an additional hidden Dao Rhyme in a state of nearing appearance yet not showing, indicating his accumulation was insufficient, causing the seventh Dao Rhyme to remain in gestation.

However, with this hidden Dao Rhyme's presence, as long as he acquired more sword cultivation knowledge in the future, he could complete this Dao Rhyme.

Li Shiming gave the flying sword a name, calling it the 'Traceless Illusion Sword' after the 'Traceless Illusion Gold' material.

He couldn't determine the grade of the 'Traceless Illusion Sword', for six and a half Dao Rhymes far exceeded the usual number for a top-level Fourth Grade Magical Treasure.

Perhaps his experience was limited, but the artifact refining scriptures he read did not mention Fourth Grade Treasures with six Dao Rhymes.

Of course, in the Cultivation World, no cultivator had ever integrated ninety million sharp runes and ten million sharp formations into a single magical treasure during artifact refining.

At least, practitioners in the Nascent Soul Stage lacked the means for such, and achieving a 5-nanometer precision in rune lines requires more than just advanced divine skill perception to see it; replicating it demands even greater control.

It required 5-nanometer precision control, a level of micro-control that, besides special existences like the machine room space, even a Great Cultivator could not achieve.

In the sky, a thundercloud was gathering.

Li Shiming exhaled slowly and decisively ordered the Gold Thunder Nascent Soul to recognize the 'Traceless Illusion Sword' as his lifebound treasure.

Upon seeing the thundercloud, he decided to face the heavenly tribulation together with the 'Traceless Illusion Sword'.

The 'Traceless Illusion Sword' lacked other supplementary laws and entirely consisted of a single law: ninety million sharp runes, forming ten million sharp formations from every nine sharp runes, representing the ultimate supplementary law manner of the 'Traceless Illusion Sword'.
