The primordial era began with the Upper Cave Man.

Chapter 473 The Successor of the Luo Ancestor's Qi Refining Technique Across Generations...

"Three strands of Purple Mansion spiritual energy, two strands of Yuan Yue spiritual energy, six strands of Golden Meteor spiritual energy, and one strand of Nameless Grade 3 spiritual energy."

"The gains from this journey between the two worlds are truly remarkable."

A faint look of joy appeared on the face of the boy from the Six Dust Realms.

"It's a pity that the world there is so barbaric, without any trace of civilization. There are many exotic flowers and herbs, and strange beasts, but unfortunately they can't come back with me. I can only pick them, refine them into various kinds of spiritual energy, and bring them back to Liuchen." The boy muttered to himself as he reached out to pick up a notebook with a sealing talisman on it that was placed on the table in the room.

"Brother, you have to help me study hard!"

The civilizations of the Six Realms are highly developed, and basic welfare includes things like giving birth and raising children, teaching knowledge, assigning work, and caring for the elderly until their death.

However, resources are ultimately limited, and these basic benefits are only the most basic for each ordinary person. Only by accumulating merit can one exchange for better benefits.

As for how to obtain merit, there are many methods, such as going to the Heavenly Demon Battlefield outside the Heavenly Membrane to resist the invasion of the Heavenly Demon Legion. This is the most direct, fastest, and also the most dangerous method.

Another example is opening up new worlds to acquire resources for the six realms of dust. This is the most unreliable. Some worlds are extremely dangerous, while others are as peaceful as a spring breeze blowing every day.

The simplest way is to use one's intelligence to gather the rare spiritual energy of heaven and earth.

The cultivation civilization in the Six Realms is highly developed and naturally has its own set of operating logic.

They divided the spiritual energy and true qi of talismans and magical artifacts into twelve levels, decreasing from one to twelve.

These grades correspond to the four realms of cultivation in the mortal world: refining essence into qi, refining qi into spirit, refining spirit into emptiness, and refining emptiness into the Dao. Each of the three levels corresponds to one of the four realms.

Based on the division of cultivation levels, these twelve levels of cultivation aids naturally have differences in energy quality.

At this age, a boy's cultivation level is only at the stage of refining essence into qi. He still has to study hard. The quality of the talismans and magical artifacts he can use is generally between level ten and twelve. The spiritual energy he gathers and refines is also like this. The true qi he refines himself cannot even be called true qi. In the common people, it is only called internal breath, but the official of the Six Dust Realms calls it level twelve true qi.

The boy usually only gathers and refines spiritual energy at levels ten to twelve. Being able to gather and refine level ten spiritual energy already shows his exceptional talent and superior physical aptitude.

Of course, one doesn't necessarily have to gather and refine spiritual energy oneself; some cultivators also use magic arrays.

Nowadays, there is a Five Elements Formation on the market that is said to be able to extract and refine the highest level of spiritual energy. It is also easy to operate and can be used for refining essence into qi.

Having spent years immersed in the Six Dusts Heavenly Network, chatting with netizens every day, the young man naturally knew it was a bunch of nonsense. Only those old men and women with bleak futures could believe it; the young man didn't believe a single word.

But he bought it anyway.

A low-grade spirit stone isn't expensive; it's just his monthly allowance.

After buying the Five Elements Formation and setting it up, he "traveled" into the body of a being from another world.

Now when he logged back into the Heavenly Network to check the Five Elements Formation, there was no information at all, as if... it was only provided to him.

Now he could only sigh that the seemingly exaggerated descriptions of the magic arrays had not deceived him; they were all true.

He went directly to another world, where spiritual energy was abundant. High-grade spiritual energy could be collected without much effort, mid-grade spiritual energy could be obtained simply by breathing, and low-grade spiritual energy... what was that? This world didn't have such a thing at all. However, top-grade spiritual energy of level three and above could be obtained with some effort. In addition, he had also unexpectedly collected and refined spiritual energy that surpassed the twelve-level classification of spiritual energy in the Six Dust Realms.

Of course, he can't be sure if it's top-grade spiritual energy. Top-grade is a name he came up with himself, and he doesn't know if the higher-ups in the Six Dust Realms have reached a conclusion on this.

To this day, he has not dared to hand over this wisp of superior spiritual energy, much less sell it; he has simply left it in that particular place.

The boy didn't even dare to hand over the top-grade and high-grade spiritual energy he collected for sale. He usually only handed over mid-grade spiritual energy, after all, he was just a high school student who had mastered the Refining Essence Qi, and his family was just an ordinary working-class family.

However, he didn't waste the high-quality spiritual energy; he used it all on himself.

Of course, the spiritual energy was of such a high grade that his physical body would not be able to withstand it if he absorbed and refined it directly. Therefore, he specially purchased a high-quality cultivation array and set it up at home. In this way, he could use it to cultivate, and his parents could also cultivate.

In addition, he would sometimes secretly release a few strands of high-grade spiritual energy for his parents to collect and refine, so that they could sell it. After all, his parents' cultivation level was much higher than his, and they had already reached the Qi Refining and Spirit Transformation stage.

As a result, the boy's family life gradually improved.

Meanwhile, the boy is quietly changing the three-eyed tribe in another world.

By gathering intelligence on various creatures, the tribesmen would not miss hunting opportunities and would also reduce the risk of dying from recklessly hunting ferocious beasts.

Of course, these matters were discussed and decided together by the human boy and the three-eyed boy.

They each had an agreement to write down their daily experiences of controlling their own bodies in this notebook.

The other world is the animal hide world.

"I wonder what shape this wisp of third-grade spiritual energy is." The boy unsealed the talisman on the notebook and then carefully read the diary left by the three-eyed boy.

This three-eyed boy was initially clumsy and slow, but he had a good learning ability. Under his guidance across time and space, he mastered the use of the Skynet, learned the language and writing of the Six Realms, and even caught up with the boy's high school courses.

This made the boy very happy.

"Huh? There are final exams next weekend? Time flies so fast?" The boy looked at the neat handwriting on the paper, somewhat dazed.

He didn't expect that this journey of swapping bodies between the two worlds would take almost half a year.

"It's time to raise my True Qi level by one level to prepare for this final exam." The boy came to his senses and made his own plans.

"Why not try this third-grade nameless spiritual energy?" The young man suddenly thought to himself.

Then he retrieved the clear yellow spiritual energy he had brought back, and with a swift movement, the young man landed in the cultivation array in the bedroom.

After settling down, he began to stammer and utter incoherently at the nameless ball of spiritual energy in his palm.

breathe…

The spiritual energy then transformed into streams of clear, bright light, gradually flowing into the boy's mouth and nose.

He is currently only at the minor stage of refining essence into qi, and his acupoints are not yet open, so he can only absorb spiritual energy through his mouth and nose.

It is said that one can also breathe through the anus and the scrotum...

An hour later, the boy finally absorbed the spiritual energy, but when he opened his eyes, a strange and puzzled expression appeared on his face.

"The Luo Ancestor's Qi Refining Technique? What is that? Where is my spiritual energy? Why hasn't my True Qi level increased by even one level?"
