Traversing countless worlds from the primordial era

Chapter 71 Civilization Leap Forward: The City-State Era

After more than 500 years of arduous cultivation, Lei Ming finally shed his mortal body and transformed into an immortal!

"I should go back to the tribe and see how Ku Yuan and the others are doing."

Lei Ming transformed into a long rainbow and headed towards Qingyu Mountain. After cultivating to become an Earth Immortal, Lei Ming's flying speed increased a thousandfold, allowing him to travel hundreds of thousands of miles in a single day. However, this speed was nothing special in the prehistoric world. Not to mention the powerful beings, some spells, such as the Somersault Cloud, could cover 108,000 miles in a single somersault.

Less than half a month later, Lei Ming returned to Qingyu Mountain. Qingyu Mountain was still the same as before, seemingly unremarkable. There were some demonic beasts in the mountain, but these beasts were not very strong, and the Twelve-Star Centipede that had killed Shi Guan was nowhere to be found.

Lei Ming flew directly to Rainbow Valley. To his surprise, there was an anti-flight formation set up above Rainbow Valley. Fortunately, the anti-flight formation was not very powerful, otherwise Lei Ming would have fallen down.

"It seems that Ku Yuan has made great progress in the art of array formations."

Lei Ming left behind a legacy that included anti-air formations. However, anti-air formations in the mortal world are only effective against cultivators below the Nascent Soul stage. The formations set up by Ku Yuan would affect cultivators below the Immortal Realm. He should be able to deduce and comprehend these formations himself; it would be absolutely impossible to do them without superb formation skills.

Lei Ming swept his divine sense across Rainbow Valley, taking in everything. Compared to when he left, the human population in Rainbow Valley had now reached tens of millions, a 100-fold increase in just over 800 years. Moreover, every human was cultivating, with the vast majority having reached the Foundation Establishment stage, half having already formed their core, and a large number of Nascent Soul cultivators. Among them, those with exceptional talent, such as Ku Yuan, had reached the peak of the Deity Transformation stage.

When Lei Ming returned to Rainbow Valley, Ku Yuan was in seclusion. Like Lei Ming, he faced the predicament of having no cultivation techniques. Over the past few hundred years, Ku Yuan had been constantly deducing, intending to perfect his own cultivation techniques. He had already deduced the techniques for the Nascent Soul stage, but he was powerless to develop any subsequent techniques.

"Ku Yuan, I'm back." Lei Ming's voice appeared in Ku Yuan's mind. Ku Yuan was shocked. He spread his divine sense to search, but found nothing.

"No need to look anymore, I'm already here."

Lei Ming appeared in Ku Yan's cave. Ku Yuan looked at him carefully and finally confirmed his identity.

"Lei Ming, you're finally back!" Ku Yuan was also very excited to see Lei Ming. "Your cultivation level... could it be that you've found the inheritance?"

Lei Ming nodded.

"Very good!"

"I came back this time to help you take another step forward. Tomorrow, gather all the clansmen who have reached the peak of the Nascent Soul stage, and I will deduce your future cultivation methods for you," Lei Ming said.

Lei Ming carved out a cave dwelling at the highest point of Rainbow Valley. He casually unleashed five array flags, and the five elements of spiritual energy within a radius of a hundred miles were immediately gathered there. He had reforged these five array flags, each reaching the level of a low-grade immortal artifact. Once the array was complete, it would be enough to resist a mid-stage Earth Immortal.

Lei Ming devoured spiritual energy like a whale sucking in water, the five elements of spiritual energy washing over his body and flowing into his dantian. Lei Ming transformed the five elements of spiritual energy into the purest chaotic spiritual power, accumulating it in his dantian. The power of the *Five Emperors' Divine Demon Scripture* lies in its ability to evolve chaos using the laws of the five elements, thereby attaining the primordial state. However, this is the highest realm of the *Five Emperors' Divine Demon Scripture*.

Under the primordial chaos, the "Five Emperors and Gods Scripture" uses the power of the five elements to refine spiritual energy to its extreme, transforming it into a spiritual power akin to chaotic energy, which the Five Elements Ancestor calls Chaotic Spiritual Power. This spiritual power is extremely pure; although it condenses very slowly, its quality is extremely high.

Lei Ming's dantian was like an ocean, with chaotic spiritual power surging within it. In terms of magical power, Lei Ming was more than ten times stronger than a terrestrial immortal of the same realm!

"The Five Emperors and Gods Scripture places great emphasis on the foundation, with each step taken steadily and surely. In particular, the method of tempering the physical body requires a great deal of effort."

Lei Ming watched the spiritual energy slowly increasing in his dantian, feeling somewhat anxious. The Five Emperors' Divine Demon Scripture was extremely powerful, but its cultivation speed was very slow, as it involved both physical and magical cultivation. Lei Ming had just begun cultivating, gathering half of the absorbed spiritual energy in his dantian and using the other half to strengthen his physical body.

Although his cultivation speed was slow, Lei Ming's strength continued to improve.

Ku Yuan led more than 10,000 clansmen to find Lei Ming. These clansmen had all reached the peak of the Nascent Soul stage, and some of them had extremely high aptitude.

Previously, Lei Ming lacked complete cultivation methods for reference, making it impossible to deduce techniques above the Nascent Soul stage. Now, having received the inheritance of the Five Elements Ancestor, deduce techniques below the Immortal Realm without much difficulty. Based on the attributes of the cultivation methods practiced by these clansmen, Lei Ming deduced ten techniques that directly lead to the Earth Immortal realm. Having obtained these techniques, the clansmen all returned to their seclusion for cultivation.

Ku Yuan was also eager to go into seclusion, so he briefly explained the situation of the tribe to Lei Ming.

After Ku Yuan left, Lei Ming considered that the tribe's population had now reached tens of millions, making it quite difficult to manage. Moreover, the tribe was still practicing the most primitive system, which was not conducive to the tribe's development.

"Civilization always progresses, and it's time for the Qingyu Mountain tribe to enter the civilized era!"

Lei Ming began to formulate a plan for the tribe's development. He skipped the era of slavery and directly led the Qingyu tribe into the civilized era. However, this was, after all, a cultivation civilization, which was different from a mortal civilization. In the mortal world, the most important thing was the means of production, while for cultivators, the most important thing was cultivation resources.

Lei Ming's core reform of the Qingyu tribe was to privatize cultivation resources. Previously, cultivation resources were communal and available to everyone. This allowed everyone in the Qingyu tribe to cultivate, regardless of their aptitude. Now, Lei Ming wanted to change this situation; he wanted to allocate more cultivation resources to tribespeople with higher aptitude.

Furthermore, Lei Ming also established a contribution system modeled after sects in the mortal world. Members of the clan must make contributions to obtain cultivation resources from the clan.

In addition to these, Lei Ming also changed the tribe's living habits. Now, almost all human tribes followed the houses built by Youchao, which were made of plants, simple to build, and sufficient to shelter from the wind and rain, but still not safe enough. Lei Ming taught his people to build houses with wood and stone, and at the same time opened their minds, allowing them to build according to their own wishes.

In just over a decade, Rainbow Valley has undergone tremendous changes. Countless stone palaces are scattered throughout the valley, in various styles, including tall stone towers, enormous palaces, and majestic pyramids... It must be said that the creativity of the human race is astonishing.

Lei Ming also attempted to create writing, for writing is the most important symbol of civilization. Having traversed two worlds, he already possessed a mature writing system in his mind. When Lei Ming wrote these characters on the stone slab, the slab immediately shattered; if the writing landed on tree bark, the bark would also burn. Not only that, a force in the void locked onto Lei Ming, and he felt that he was in danger of being destroyed at any moment.

Lei Ming quickly stopped creating characters, and only then did the power dissipate.

"Now is not the time for written language to be invented," Lei Ming said, somewhat unwillingly.

More than 100 years later, the Qingyu tribe fully entered the city-state era. More than 1000 million tribesmen built Rainbow City above Rainbow Valley. Leiming was the natural city lord, and Kuyuan was the deputy city lord.

Rainbow City established its own armed force, led by Ku Yuan, which included many Earth Immortals. With this force, Rainbow City expanded its territory to a radius of ten thousand miles and also annexed two other human tribes.

Rainbow City's fame spread far and wide, even reaching the three ancestors of the human race in Buzhou Mountain, the ancestral home of the human race.

After Lei Ming established Rainbow City, his cultivation became increasingly smooth. In just over 100 years, he progressed from the early stage of Earth Immortal to the late stage. Lei Ming knew that this was due to the influence of luck.

"No wonder even saints vie for fortune," Lei Ming sighed, deciding to continue expanding outwards and grow Rainbow City as strong as possible.

Ku Yuan also reached the Earth Immortal realm. He cultivated ordinary techniques, and with the help of luck, his cultivation speed was much faster than Lei Ming's back then.

That day, Ku Yuan approached Lei Ming to discuss matters concerning the ancestral land of the human race.

"Our human race has existed for a thousand years. When we left, our three ancestors made a pact that a thousand years later, all tribes would come to our ancestral land to pay homage to the Holy Mother. Judging by the time, that time is almost here," Ku Yuan said.

Lei Ming nodded; he knew about this as well.

"I'll lead the people to the ancestral land this time." Lei Ming was eager to know what realm the three ancestors of the human race were at now.

"The millennium has come to an end." Above Mount Buzhou, a streak of azure light descended, and white light rose from the land within a radius of tens of millions of miles. The azure light and white light merged and vanished into nothingness.
