Cultivation is just so scientific!

Li Shiming, with the enthusiastic booklets given to him by Senior Brother Zhu Ji, returned to his own small room.

He first activated the Cleaning Spell on his robe with spiritual power, sweeping his body from the inside out with a wave of spiritual energy, refreshing even the inside of his mouth.

In fact, ever since they stopped consuming mortal food, it had become difficult for cultivators' bodies to accumulate impurities.

As early as when a Spiritual Energy Vortex formed inside their bodies, making them official cultivators, most of the impurities within were expelled.

Apart from each major advancement in their realm, which would expel deeper impurities from the body, even without cleaning for ten or fifteen days, cultivators could still maintain the cleanliness of their entire body.

It is only for disciples in the early-stage Qi Refining that the sect would issue robes with cleaning functions; middle-stage and late-stage Qi Refining cultivators usually choose to buy their own robes or select better ones from the sect.

After reading through the booklets, Li Shiming realized that this was not some spell but merely a skill in utilizing spiritual power.

The spiritual power of normal cultivators was highly lethal to vengeful ghosts. Although the ghosts in the Five Ghosts Soul Refining Banner had been made more powerful by the Xuanming Sect cultivators' refining, without their master, the ghosts could not leave the Five Ghosts Soul Refining Banner.

As long as the appropriate spiritual power was used to continuously sweep over the Five Ghosts Soul Refining Banner, the resentment of the ghosts within could be weakened.

It was simple, yet very practical. The most important thing mentioned in the booklets was the appropriate timing.

Too much spiritual power could cause substantial damage to the Five Ghosts Soul Refining Banner, resulting in the destruction of the five vengeful ghosts, while too little wouldn't diminish the resentment effectively.

The booklets were a compilation of many cultivators' successful experiences, and it was probably only sects like Sky Sea Sect, which were mortal enemies of the Xuanming Sect, that would have cultivators researching this area and achieving results.

Li Shiming took out a Five Ghosts Soul Refining Banner, and upon its removal, the figures of the five ghosts were tumultuously tumbling on the banner's surface.

He mobilized his spiritual power, sweeping his hand across the banner.

The spiritual power contacted the five ghosts, emitting a hissing dissolving sound, and the shrill screams of the ghosts followed.

Li Shiming, who had suffered spiritual backlash from the copper corpse, felt no discomfort from the ghosts' screams, repeatedly sweeping his spiritual power over the Five Ghosts Soul Refining banner.

The blackness on the bodies of the five ghosts grew fainter, and they became quieter.

Li Shiming did not stop until he saw that the bodies of the ghosts had become transparent, then he stopped the spiritual power cleansing process.

He flicked the Five Ghosts Soul Refining Banner with his finger channeling spiritual power, prompting a phantasmal Rune Array to surface on the banner.

"Dragon Drawing!" As his spiritual power swept over the rune array, the Rune Array truly manifested.

"Bright Eyes!" Two bright spots appeared on the Rune Array, and he invoked the Dragon Drawing Technique to touch them.

The Dragon Drawing Technique was indeed a divine technique for refining magic artifacts, and this Five Ghosts Soul Refining Banner was now refined by him.

Of course, the degree to which the Five Ghosts Soul Refining Banner was refined was very low, but there was no need for the banner to participate in battle. It was enough that it was refined for use.

He gently shook the Five Ghosts Soul Refining Banner, and five transparent ghost figures drifted out from within the banner.

"That's unscientific!" Since Li Shiming had come into contact with the Cultivation World, he had uttered the questioning of his soul countless times.

The five ghost figures in front of him proved the existence of ghosts in this world, and through the Five Ghosts Soul Refining Banner, he could decide the life or death of the five ghost figures with a single thought.

The five ghost figures relied on resentment, but at this moment, the resentment within the ghost figures was barely one-tenth of its original strength. They were completely existing because of the Five Ghosts Soul Refining Banner.

Li Shiming discovered that the five ghost shadows seemed to lack intelligence; he could perceive everything about them, including the thoughts of the ghost shadows.

Within the minds of the five ghost shadows, there were only emotions of fear and terror. Their level of intelligence was roughly that of a three-year-old child.

After conducting more experiments, although the five ghost shadows appeared transparent and had lost most of their resentment, their weakness was only relative to cultivators.

In any mundane setting, any one of these ghost forms could easily outmatch so-called mortal experts.

What was most crucial was that with the "Five Ghosts Soul Refining Banner" nearby, if the five ghost shadows took turns resting, they could indeed be used as a perpetual motion machine.

Thinking of perpetual motion machines, a contemplative look appeared on Li Shiming's face.

There seemed to be a real possibility of using the ghost shadows from the "Five Ghosts Soul Refining Banner" as a power source.

He also had another "Five Ghosts Soul Refining Banner," which meant he would have a total of ten ghost shadows.

In the engine room, diesel generators were constantly working, and he had also prepared plenty of diesel, filling several storage bags and several large barrels in the engine room space.

But without replenishment, the diesel would one day be exhausted.

At the time, he had considered using his talent with talismans to find electrical runes to address the power supply issue.

Now, with a preliminary alternative plan, he could temporarily free himself from the constraints of diesel.

Using ghost shadows as the driving force, the ghosts would propel the generator to produce electricity, and when the ghosts became tired, a new group would take over while the weary ones rested inside the "Five Ghosts Soul Refining Banner."

As for the safety of the engine room space, he didn't plan to remove the "Five Ghosts Soul Refining Banner," and considering the intelligence of the ghost shadows, there was no risk of them revealing the engine room's location.

With this in mind, he first purified the other "Five Ghosts Soul Refining Banner" and refined it using the "Dragon Drawing Technique."

He then redesigned a generator powered by ghost shadows in the IBM z15, accurately inputting the strength of the ghost shadows to calculate the most suitable size for the generator.

Because the power was absolutely clean, the generator could utilize the cramped space of the engine room to the maximum extent, achieving ideal electrical output.

Modifying the generators didn't take long, as the materials were prepared in advance. Working on the existing generators, the amount of work involved was not substantial.

What was most critical was that ten ghost shadows entered the engine room space and, collaborating with his consciousness, greatly accelerated the work progress.

The ghost shadows were not afraid of high temperatures and could help in molding the workpieces.

On that very day, a special perpetual engine came into existence.

Three ghost shadows were positioned at the rotor of the perpetual engine, each pushing a fan blade fixed onto it. The three blades caused the rotor to start spinning.

In an instant, the ghosts shadowed whirled, and mist swirled around as the three propelled the perpetual engine into motion.

Apart from the eerie special effects, the results were exceptional.

Each of the three ghost shadows had a strength exceeding two hundred kilograms, and with their incredible speed and coordination, the energy expended in turning the rotor was minimal for them.

Ghost shadows didn't need to worry about getting dizzy from spinning too much, as such a concern was nonexistent for them.
