Li Yao's eyelashes trembled and his face was dignified. The "Great Dark Age" was the most important period in the development of Xiuzhen civilization. It can even be said that it was the great dark age that divided the "classical Xiuzhen period" and "modern Xiuzhen period". This is a very classic question, which is well known, but it is not easy to answer comprehensively.

After pondering for a moment, Li Yao's mind turned and his mind soared

"With the goal of immortality, the ancient practitioners created a splendid ancient civilization. They established an upgrading system from refining Qi and building foundation to jiedan and Yuanying, and then to Dujie, Zhenxian and immortality. They went forward bravely along this road, constantly opened up the limit of life, and marched towards the endless sea of stars."

"In the heyday of the ancient civilization, the ancient monks opened up one world after another, built an ancient transmission array 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 ancient cultivation civilization, ancient practitioners have become more and more powerful and long-lived, and there are more and more strong ones."

"In the early period of the ancient civilization, there were only hundreds of practitioners in the golden elixir period and dozens of practitioners in the Yuan Dynasty. As for" transforming the old gods and monsters "and" robbing the real king ", they were unheard of. Only one could appear in dozens of worlds and thousands of years. It is absolutely rare."

"But in the late period of the ancient civilization, like the big bang, the high-level practitioners multiplied by geometric progression. At that time, there was a saying that" Yuan babies were as many as dogs, and the spirits were everywhere. "

"So many high-level practitioners need huge resources to practice. In addition, more and more practitioners have achieved immortality, and their thirst for resources has reached infinity!"

"At the beginning, we could satisfy the greedy high-level practitioners by developing a new world. However, after tens of thousands of years of development, we discovered nearly 5000 worlds. For a whole thousand years, the ancient civilization failed to discover even a new world.

"The world is limited, and the demands of the practitioners are unlimited - it took the ancient practitioners a thousand years to understand this truth. It is natural that in order to fight for limited resources, civil war broke out immediately."

"Three thousand years of civil war swept the whole world. Gu Xiu, who can call the wind and rain and move mountains and seas, fought against each other on every star! The stars are burning, the ancient teleportation array is destroyed, the crystal warships are exploding, and the so-called "immortal" high-level practitioners are falling down one after another. The "jiedan strongman" and "Yuanying old monster" are just like the mortals they once regarded as ants, and they have become worthless cannon fodder, which is destroyed by the attack of destroying the planet. "

"In the late period of the civil war, more than 70% of the world was destroyed, and countless worlds were cut off from the main world. More than 90% of the high-level practitioners turned to ashes, and the rest of the low-level practitioners also survived in the ruins."

"It seems that war is hard to maintain, and the dawn of peace appears - until in an unknown world, an ignorant cultivation genius invents a" gadget. "

"The name and sect of this cultivation genius can no longer be verified, and his refining process has long gone with the wind. Modern people call what he created - Demon God virus!"

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

"He succeeded. Through the catalysis of the" demon God virus ", countless docile spirit beasts have been modulated into terrible killing tools. The war machine known as" demon beast "is tireless, never hesitant and never dies!"

"In just ten years, this cultivation genius unified the world where he lived by virtue of the army of demons and beasts, and the number of demons and beasts reached hundreds of millions. The practitioners of other worlds discovered what he had done and began to refine their own" demons and beasts. "

"For a hundred years, monsters have become the main force of the civil war in Xiuzhen world, appearing in every corner of the sea of stars."

"However, all practitioners have not found two things."

"First, demon God virus has a strong ability of self replication and infectivity."

"Second, the" demon God virus "not only improves the combat effectiveness of monsters, but also imperceptibly improves their intelligence. In hundreds of years of brutal bloody war, under the catalysis of a huge base, among the monsters with trillions of calculations, a" demon tribe "with intelligence comparable to human beings has been born!"

"Finally, on the last day of the 3000 year civil war, the demon clan awakened!"

"It seems that under the command of some terrible existence, all the monsters of the world in the sea of stars rise up almost at the same time to resist their domination. The practitioners who have been hiding in the mountain gate for hundreds of years are not the opponents of the monsters who have been in the battlefield for a long time - not to mention the demons who have mastered the human cultivation technology!"

"One Lingshan mountain after another has been razed to the ground, and one sect after another has been slaughtered. For a hundred years, the demon clan has been chasing every one of the practitioners who have missed the net in the sea of stars. The former high-ranking practitioners are like dogs who have lost their families, hiding in the darkness of the sea of stars and the gap between time and space. They are in constant panic."

"Thirty thousand years later, it was the" Great Dark Age "of human beings. In the endless darkness, the demon clan established a huge" demon Dynasty ", while human beings were reduced to humble slaves, losing dignity, pride, and the most precious power of cultivating truth and Qi."

"Thirty thousand years, thirty thousand years! The ancient civilization, which used to dominate the endless sea of stars, is just like the tower of yellow sand. It was destroyed by the waves, leaving no mark! In the past, the descendants of the "immortal" high-level practitioners had to rely on the most primitive and powerful reproduction to maintain the continuity of the race with a large number of people. "

"It was not until 30000 years later, at the end of the great dark age, when the demons competed for power and profits, and the contradictions became increasingly acute, that human beings got a chance to breathe. With the unremitting efforts of countless cultivation talents, human beings launched three" cultivation revolutions "in secret, and established a" modern cultivation civilization system "which was completely different from the ancient cultivation civilization, Only then embarks on the magnificent road of cultivation, the road of rejuvenation

"Under the leadership of the mighty emperor, human beings excavated a large number of relics of ancient civilization and re established 20" Yuanshi sects ". After thousands of years of bloody battles, humanity prospered, and human beings became the master of the endless sea of stars again. Modern civilization of cultivation also radiated vitality."

"It's 10000 years since the end of the great dark age, and it's 40000 years since the collapse of the ancient civilization. Now, it's the best age of cultivation. It's the 40000 years of cultivation with endless charm."

When Li Yaosi finished the last paragraph of the exam, a countdown appeared in the sky, which represented the end of the exam. He had no choice but to give up the idea of continuing to explain the life of the emperor. He casually said a few routine words and hastened to the end.

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