Li Yao's eyelashes twitched, and his face was a little solemn, the "Great Dark Age" is the most important period in the development of Xiuzhen civilization, and it can even be said that it is the Great Dark Age that divides the "Classical Xiuzhen Period" and the "Modern Xiuzhen Period", this is a very classic question, everyone knows it, but it is not easy to answer comprehensively.

After pondering for a moment, Li Yao's mind was racing, and his thoughts were flying:

"The ancient cultivators took immortality as the goal and created an incomparably brilliant ancient cultivation civilization, and they established a foundation from refining qi and building a foundation to knotting Dan and Yuanying...... Until the escalation system of Tribulation, True Immortal, and Immortal, and move forward bravely along this path, constantly exploring the limits of life, and moving towards the endless sea of stars. ”

"In the heyday of the ancient cultivation civilization, the ancient cultivators opened up one world after another, built an ancient teleportation array that ran through the endless sea of stars, shuttled between the stars and the world at will, and even began to explore the ultimate mystery of time!"

"With the continuous evolution of the ancient cultivation civilization, the ancient cultivators became more and more powerful, more and more long-lived, and the number of strong people also increased."

"In the early stage of the ancient cultivation civilization, there were only hundreds of Jindan stage cultivators in the three thousand worlds, dozens of Yuan Infant stage cultivators, as for the 'Transformation of God Old Monster' and 'Crossing the Tribulation True Monarch' are unheard of, dozens of worlds, thousands of years can only appear one, it is definitely a rare existence!"

"However, in the later stage of the ancient cultivation civilization, like a big bang, the number of high-level cultivators multiplied by geometric progression-at that time, there was a saying that 'there are as many primordial babies as dogs, and they turn into gods and walk all over the ground'."

"So many high-level cultivators need huge resources to cultivate, plus more and more cultivators have reached near-immortality, and their thirst for resources has also reached - endless!"

"In the beginning, it was possible to develop new worlds to satisfy greedy high-level cultivators, but after tens of thousands of years of development and the discovery of nearly five thousand worlds, for a full thousand years, the ancient cultivation civilization failed to discover even one new world.

"The world is limited, but the demands of the cultivators are infinite - it took the ancient cultivators a thousand years to understand this truth, and it was logical that in order to compete for limited resources, a civil war broke out immediately."

"Three thousand years of civil war have swept through the entire world, and the ancient cultivators who can call the wind and rain and move mountains and seas are fighting each other on every star! The planet was burning, the ancient teleportation array was destroyed, the spar battleship exploded in a row, and the high-level cultivators known as the 'immortals' fell one after another, and the 'Yuedan Strong' and the 'Yuan Infant Old Monster' became worthless cannon fodder like the mortals they once regarded as ants, and were wiped out under the attack that was enough to destroy the planet. ”

"In the later stage of the civil war, more than seventy percent of the worlds were destroyed, and countless worlds were cut off from the main world, more than ninety percent of the high-level cultivators turned into ashes, and the remaining low-level cultivators also survived in the ruins."

"War seemed untenable, and the dawn of peace loomed - until an ignorant cultivation genius invented a 'gadget' in an unknown world."

"The name and sect of this cultivation genius are no longer verifiable, and his refining process has long since passed away with the wind, and modern people call the thing he created - Demon God Virus!"

"Maybe his idea is very simple: since there are not enough warriors, why not invent something to comprehensively improve the combat power of spirit beasts and fight instead of cultivators - after all, the number of spirit beasts is almost infinite!"

"He succeeded, after the catalysis of the 'Demon God Virus', countless tame spirit beasts were concocted into terrifying killing tools, known as the 'Demon Beasts', the war machine qì, tireless, will not hesitate, and will not die!"

"In just ten years, this cultivation genius has unified the world he is in with the army of demon beasts, and the number of demon beast armies has also reached hundreds of millions, and the cultivators of the rest of the world have discovered what he has done, and they have also begun to refine their own 'demon beasts'."

"In a hundred years, demon beasts have become the main force in the civil war in the cultivation realm, appearing in all corners of the sea of stars."

"It's just that none of the cultivators have discovered two things."

"First, the 'demon god virus' has a strong self-replication ability and infectiousness."

"Second, the 'Demon God Virus' is not only improving the combat effectiveness of the demon beasts, but also imperceptibly improving the intelligence of the demon beasts, and in the cruel bloody war of hundreds of years, under the catalysis of the huge base, among the trillions of demon beasts, the 'demon race' with intelligence comparable to that of humans was born!"

"Finally, on the last day of the three-thousand-year civil war, the demon clan has awakened!"

"As if under the command of some terrifying being, the demon beasts of all the worlds in the sea of stars rose up to rebel against their masters almost at the same time, and the cultivators who have been hiding in the mountain gate for hundreds of years are not the opponents of the battle-hardened demon beasts at all—not to mention the demon clans that have mastered the human cultivation technique!"

"One spiritual mountain after another has been razed to the ground, one sect after another has been slaughtered, in a hundred years, the demon clan has been frantically chasing every cultivator who has slipped through the net in the sea of stars, and the cultivators who were high above in the past are like lost dogs, hiding in the dark domain of the sea of stars and the cracks of time and space, and they can't live in fear."

"After that, for the entire 30,000 years, it was the 'Great Dark Age' of human beings, in the endless darkness, the demon clan established a huge 'Demon Beast Dynasty', and human beings have become lowly slaves, losing their dignity, losing their pride, and losing the most precious thing - the power to cultivate true qi and refine qi!"

"Thirty thousand years, a full thirty thousand years! The ancient cultivation civilization that was brilliant in the past and ruled the endless sea of stars was like a tower of yellow sand, destroyed by the stormy waves, leaving no trace! In the past, the descendants of the 'immortal' high-level cultivators could only rely on the most primitive and powerful fecundity to maintain the continuation of the race with a huge number! ”

"It wasn't until 30,000 years later, at the end of the Great Dark Age, that the demon clan struggled for power and profit, and the contradictions continued to sharpen, that human beings got a chance to breathe, and under the unremitting efforts of countless cultivation geniuses, human beings secretly launched three 'cultivation revolutions', and established a 'modern cultivation civilization system' that was completely different from the ancient cultivation civilization, and then re-embarked on the magnificent road of cultivation and rejuvenation!"

"Under the leadership of the peerless powerhouse 'Emperor', mankind excavated a large number of relics of ancient cultivation civilization, and re-founded twenty 'Yuan Shi Sects', after thousands of years of bloody battles, humanity has become the master of the endless sea of stars, and the modern cultivation civilization has also radiated vitality!"

"It has been 10,000 years since the end of the 'Great Dark Age', and it has been a full 40,000 years since the collapse of the ancient cultivation civilization, and now, it is the best Xiuzhen century, and it is the 40,000 years of Xiuzhen with infinite charm!"

When Li Yao was thinking about the last paragraph, there was a countdown in the sky that represented the end of the exam, and he had to give up the idea of continuing to elaborate on the life of the "emperor", and casually said a few clichés and hurriedly ended.

Almost at the moment when the last word came to mind, the whole world collapsed with a bang, turning into butterfly-like fragments, Li Yao was forcibly pushed out by a strong force, and his consciousness returned to the classroom.
