Li Shiming returned to his own room with the book that Brother Zhu Ji had given him enthusiastically.

He first used his spiritual power to activate the cleansing spell on his robe. A stream of spiritual power swept through his body from inside to outside, and even his mouth felt refreshed.

In fact, since the monks no longer eat mortal food, it is difficult for their bodies to be contaminated.

As early as when the spiritual energy vortex was formed in the body and he became a formal cultivator, most of the impurities in the body were eliminated.

In addition to the fact that each time a great realm is promoted, deep-seated impurities in the body will be expelled, even if a cultivator has not cleaned his body for ten days or half a month, he can still keep his whole body clean.

That is to say, the sect will only distribute robes with cleaning function to disciples in the early stage of Qi Refining. Most cultivators in the middle and late stages of Qi Refining choose to buy robes by themselves, or choose better robes from the sect.

Li Shiming took out the book and read it through. He realized that this was indeed not a spell, but just a technique for using spiritual power.

The spiritual power of a normal cultivator has great lethality to evil spirits. Although the evil spirits in the 'Five Ghosts Soul Refining Banner' have become more powerful after being refined by the cultivators of the Xuanming Sect, the 'Five Ghosts Soul Refining Banner' has lost its owner and the evil spirits in it cannot leave the 'Five Ghosts Soul Refining Banner'.

As long as you use the right amount of spiritual power to continuously clean the 'Five Ghosts Soul Refining Banner', you can reduce the resentment of the evil spirits within it.

It is very simple, yet very practical. The most important thing in this book is the right timing.

If too much spiritual power is used, it will cause too much damage to the 'Five Ghosts Soul Refining Banner', thus causing the five evil ghosts to be eliminated. However, if too little spiritual power is used, it will not have the effect of weakening the resentment.

The book is a record of the successful experiences of many cultivators. It is estimated that only a sect like Tianhai Sect, which is a mortal enemy of Xuanming Sect, would have cultivators to conduct research in this area and achieve results.

Li Shiming took out a 'Five Ghosts Soul Refining Banner'. After the 'Five Ghosts Soul Refining Banner' was taken out, the figures of five evil ghosts kept rolling on the banner.

He mobilized his spiritual power and swept his hand across the banner.

The spiritual power came into contact with the five evil spirits, causing a hissing sound of dissolving, followed by the shrill howls of the five evil spirits.

Li Shiming, who was attacked by the bronze corpse's spirit, was not at all uncomfortable with the shrill howls of the five evil ghosts. He used his spiritual power to sweep the 'Five Ghosts Soul Refining Banner' over and over again.

The black color on the five evil spirits became lighter and lighter, and they became quieter.

Li Shiming did not stop until he saw the evil ghost's body became transparent, then he stopped the process of clearing the spiritual power.

He mobilized his spiritual power with his fingers and flicked the 'Five Ghosts Soul Refining Banner', and an illusory rune array appeared on the 'Five Ghosts Soul Refining Banner'.

"Draw a dragon!" As his spiritual power swept across the rune array, the rune array truly appeared.

"Point the finishing touch!" Two bright spots appeared on the rune array, and he used the 'Painting the Dragon's Finishing Touch' to point them.

The 'Painting the Dragon's Eyes Technique' is indeed a magical skill for refining magical instruments. This 'Five Ghosts Soul Refining Banner' was refined by him.

Of course, the degree of refining of the 'Five Ghosts Soul Refining Banner' is very low, but there is no need for the 'Five Ghosts Soul Refining Banner' to participate in the battle, as long as it is refined it is enough.

He gently shook the 'Five Ghosts Soul Refining Banner', and five transparent ghost shadows floated out from the 'Five Ghosts Soul Refining Banner'.

"This is unscientific!" Li Shiming questioned his soul countless times after coming into contact with the world of immortal cultivation.

The five ghosts in front of him showed that there were ghosts in this world, and through the 'Five Ghosts Soul Refining Banner', he could decide the life or death of the five ghosts with just a thought.

The five ghosts rely on resentment, but at this moment only one tenth of the resentment remains in the ghosts' bodies, and they exist entirely relying on the 'Five Ghosts Soul Refining Banner'.

Li Shiming discovered that the five ghosts did not seem to have much intelligence. He could sense everything about the five ghosts, including their inner thoughts.

The five ghosts only have fear and terror in their hearts, and their intelligence is probably at the level of a three-year-old child.

He experimented again. Although the five ghost shadows looked transparent and had lost most of their resentment, their strength was only weak compared to cultivators.

Any ghost of this form that appears in the secular world can defeat the so-called mortal masters.

The most important thing is that with the 'Five Ghosts Soul Refining Banner' nearby, if the five ghosts take turns to rest, it can be used as a perpetual motion machine.

Thinking of the perpetual motion machine, a thoughtful look appeared on Li Shiming's face.

It seems that there is really such a possibility, using the ghost shadows in the 'Five Ghosts Soul Refining Banner' as power.

He also has a 'Five Ghosts Soul Refining Banner', which means there are ten ghost shadows.

In the engine room, the diesel generator has been working. He has also prepared a lot of diesel, filling several storage bags. There are also several large barrels filled with diesel in the engine room.

But without replenishment, the diesel will eventually run out.

What he was thinking at the time was to use his talisman ability to find a talisman that could stimulate electricity to solve the problem of electricity demand.

Now there is a tentative alternative that could allow him to temporarily escape the constraints of diesel.

Using ghosts as power, the ghosts push the generator to generate electricity, and when the ghosts are tired, a new group of ghosts will be replaced, and the tired ghosts will enter the 'Five Ghosts Soul Refining Banner' to rest.

As for the safety of the computer room space, not to mention that he had no intention of taking out the 'Five Ghosts Soul Refining Banner' for use, even with Ghost Shadow's wisdom, there was no danger of leaking the computer room space.

Thinking of this, he first used the same method to purify the other side of the 'Five Ghosts Soul Refining Banner', and then refined it with the 'Dragon's Finishing Technique'.

Later, he redesigned the ghost-powered generator in IBM z15. He substituted the accurate ghost power and calculated the most suitable generator size.

Because the power is absolutely clean, the generator can make maximum use of the limited space in the machine room and obtain the most ideal electricity.

It did not take long to modify the generator as the materials had been prepared long ago and the work involved in modifying the old generator was not large.

The most important thing is that ten ghosts entered the computer room and, cooperating with his consciousness, sped up the work progress a lot.

Ghost images are not afraid of high temperatures and can help shape workpieces.

On that day, a special perpetual motion generator was born.

The three ghost images are at the rotor position of the perpetual motion generator, each pushing a fan blade fixed on the rotor, and the three fan blades drive the rotor to rotate.

In an instant, ghost shadows fluttered, ghost mist swirled, and three ghost shadows drove the perpetual motion generator.

Aside from the fact that this special effect is a bit creepy, the effect is excellent.

Each of the three ghost shadows has a power of more than two hundred kilograms, and coupled with their extremely fast speed, their coordinated operation consumes very little energy to drive the rotors.

There is no need to worry about getting dizzy from turning too much when playing with ghosts, as this situation does not exist at all.
