Cultivation is just so scientific!

Li Shiming sensed the fatigue of the Heavenly Ghost, he shook his head and waved to retract the Great Cultivator's body back into the engine room space, allowing the Heavenly Ghost to leave the Great Cultivator's body for rest.

He casually took out a third-grade top 'Spirit Worm Golden Yang Pill', from his sleeve, the 'Silver Winged Spirit Gu Insect' flew out and swallowed the 'Spirit Worm Golden Yang Pill' in one go.

The 'Silver Winged Spirit Gu Insect' let out a light chirp after swallowing the 'Spirit Worm Golden Yang Pill'.

This light chirp carried emotions of joy.

The 'Silver Winged Spirit Gu Insect' flew back into his sleeve, this chirp was a thank you to Li Shiming.

It had been several tens of days since the 'Silver Winged Spirit Gu Insect' consumed the first top-grade 'Spirit Worm Golden Yang Pill'.

Each time the 'Silver Winged Spirit Gu Insect' consumed a top-grade 'Spirit Worm Golden Yang Pill', its emotions grew slightly.

Now Li Shiming didn't need to put the 'Silver Winged Spirit Gu Insect' into the 'Gu Wind Bag', as without the control of twenty brains, the 'Silver Winged Spirit Gu Insect' would quietly stay by his side.

During this time, the frantic emotions of the 'Silver Winged Spirit Gu Insect' weakened more and more, especially when staying on Li Shiming's body, the frantic emotions magically disappeared.

After the frantic emotions disappeared, he was able to sense from the contract the faint attachment the 'Silver Winged Spirit Gu Insect' had towards him.

As the number of top-grade 'Spirit Worm Golden Yang Pills' consumed increased, this faint attachment continued to grow stronger.

The thing that satisfied him most about the 'Silver Winged Spirit Gu Insect' was its formidable ability to conceal its aura when not in combat, making it impossible for other cultivators to sense the presence of the 'Silver Winged Spirit Gu Insect' even when close to Li Shiming.

Of course, when the 'Silver Winged Spirit Gu Insect' was in combat mode, its fierce aura could not be hidden.

He took out a batch of 'Spiritual Beast Essence Boosting Pill', and as soon as he did, Little Feng and the Illusion Spirit Dragon came rushing in from outside.

Little Feng and the Illusion Spirit Dragon had transformed into smaller bodies to move more freely within the cave.

Since Little Feng matured, its energy needs increased considerably.

Fortunately, 'Spiritual Beast Essence Boosting Pill' is also a third-grade Spirit Pill, and his speed in refining third-grade Spirit Pills was quite fast, enough to meet Little Feng's needs.

It's quite funny that when Little Feng first saw the 'Silver Winged Spirit Gu Insect', it thought of it as food.

It took a good explanation from Li Shiming to make Little Feng dispel that thought.

Li Shiming had no intention of having Little Feng try to attack the 'Silver Winged Spirit Gu Insect', as the 'Silver Winged Spirit Gu Insect' had extremely sturdy defensive power, but Little Feng was a natural Red Gold Phoenix with the ability to burn the soul.

He didn't want to find out whether the 'Silver Winged Spirit Gu Insect' could withstand Little Feng's soul flames, as the 'Silver Winged Spirit Gu Insect' was an important combat force for him and couldn't be damaged out of mere curiosity.

He checked his Identity Jade Disc and found some messages from cultivators requesting Elixir Pills, he replied to each message and set up times.

Even though he was in isolation, he still accepted alchemy business, which was his main source of income.

Most importantly, taking on alchemy business also constantly increased his Elixir Pills stock, which were his cultivation resources.

He left the Fire Thunder Nascent Soul out of cultivation specifically to use 'Nanming Leaving Fire' for alchemy.

Now that the Golden Corpse Nanming had finished refining the late-stage Nascent Soul healing Spirit Pill, it could also conduct alchemy alongside Fire Thunder Nascent Soul.

Aside from alchemy, he also planned to refine the Fourth Grade Puppets and 'Traceless Illusion Gold', but these were not urgent, and required a lengthy design period.

Time passed quickly, in the blink of an eye, two years had gone by.

During these two years, Li Shiming never left his cave, all his outside contact was through the Heavenly Ghost controlling a Body Refining Great Elder Living Dead named Li Si.

Over these two years, his greatest achievement was completing the refining of three Fourth Grade Puppets and almost finishing the work on the 'Traceless Illusion Gold' flying sword artifact, with only one last step remaining.

Li Shiming stared at the three Fourth Grade Puppets in front of him, these three Fourth Grade Puppets were quite unusual, not the same as the Fourth Grade Xuanjia Puppets.

The three Fourth Grade Puppets were designed for speed, and he used his unique techniques to inscribe eight hundred thousand acceleration runes on their feet.

This made the three Fourth Grade Puppets extremely fast, and due to the material and his design philosophy, the defensive power of the three Fourth Grade Puppets was not strong, able only to withstand a full-force strike from a Nascent Soul Early Stage Practitioner.

This level of defensive power was too weak for a Fourth Grade Puppet, and he lacked the Fourth-grade Puppet Mechanism Materials required to make frontal armor for the Fourth Grade Puppets.

He left interfaces for the Fourth Grade Puppets, so that he could add on the armor once he acquired those materials in the future.

But actually, adding it or not didn't matter, as he never intended for the three Fourth Grade Puppets to engage in close combat.

Normally, Fourth Grade Puppets were primarily for close combat, acting as a mobile shield for cultivators, absorbing a portion of the attacks for them.

However, Li Shiming designed a new weapon, the electromagnetic cannon, for the Fourth Grade Puppets, freeing them from the constraints of close combat, with the power of the long-range electromagnetic cannon attacks far surpassing that of melee combat.

For this reason, the three Fourth Grade Puppets he refined did not require overly strong defenses, but instead had a high need for speed.

Unfortunately, the Fourth-grade Puppet Mechanism Materials for making feet could only bear eight hundred thousand acceleration runes before reaching their limits, otherwise, he could have added more acceleration runes to the feet of the Fourth Grade Puppets.

By relinquishing close combat, the energy core of the Fourth Grade Puppets had more energy to supply to the electromagnetic cannon, thus greatly enhancing the power of the electromagnetic cannon.

With four Fourth Grade Electromagnetic Cannon Puppets, under the control of his life-bound artifact IBMz15, he could effectively launch a devastating first strike.

The effective attack range of the electromagnetic cannon was currently five Baili, within five Baili, even a Nascent Soul Middle Stage Practitioner, if completely unguarded and hit by a simultaneous focus fire from four electromagnetic cannons, could be seriously wounded.

Besides the Fourth Grade Electromagnetic Cannon Puppets over the two years, the only other achievement was the flying sword artifact which was one step away from completion.

He had gone to great lengths to refine the 'Traceless Illusion Gold'.

'Traceless Illusion Gold' cannot be detected by Divine Sense, as if it were nothingness, but it can be physically touched.

Fortunately, in the engine room space, 'Traceless Illusion Gold' could be sensed using 5-nanometer control to interact with it.

'Traceless Illusion Gold' is extremely difficult to smelt, due to its high grade, as fourth-grade top materials are not typically reachable treasures for Nascent Soul Early Stage Practitioners.

Normally, fourth-grade top materials are only attainable by Great Cultivators.

Li Shiming devised a method, allowing Golden Corpse Nanming and Fire Thunder Nascent Soul to jointly use 'Nanming Leaving Fire', and it was this combination that allowed 'Traceless Illusion Gold' to melt.

For this flying sword artifact, he had a special design concept, that is the ultimate sharpness.

There was no need to consider speed, durability, and such factors, the sharpness alone had to be extremely high.

Given 'Traceless Illusion Gold' is invisible, and coupled with the use of Li Shiming's unique Sword Cultivator techniques, there was a certain guarantee of speed, albeit speed was not the primary concern.

'Traceless Illusion Gold' by itself is incredibly durable, considering the conditions required to smelt it—two Nascent Soul Level 'Nanming Leaving Fire' flames were barely sufficient to melt 'Traceless Illusion Gold'.

Long hours of 'Nanming Leaving Fire' scorching were needed to finally melt the 'Traceless Illusion Gold' for artifact refining.

The real emphasis for this flying sword artifact was on its extreme sharpness.

The flying sword artifacts were inscribed with ninety million sharp runes at 5-nanometer precision.

As for speed, 'Traceless Illusion Gold' is invisible, and combined with Li Shiming's unique Sword Cultivator skills, speed was assured to some extent, but it wasn't the primary factor.
