There is no way to verify how long the desolate world existed, but according to historical research, it is divided into four periods, namely primeval, ancient, medieval and present.

In the primeval period, the Demon Ancestor and the Wu Clan dominated the desolate world, and other races were just vassals and even slaves, like the human race was not even a slave in that period, just food.

After the Lich War, the desolate world was almost shattered, the Hongmeng tree was destroyed, and the vitality of heaven and earth was seriously lost, so as to use this as a demarcation point to enter the era of the end of the law, also known as the ancient era. It's just that the ancient era can't be accurately called the end of the Dharma era, because the speed of the loss of heaven and earth vitality is not too fast, although you can feel the continuous loss of heaven and earth vitality, it will not cause much impact in the short term.

During this period, the witch race and the demon race withdrew from the stage of history, and the human race began to flourish, why the human race? It was because the Terrans were too weak at that time.

In the primeval period, the human race was not even a slave, it could only be a mouthful of food, and the Lich War was not just a war between two races, but a war between two camps, and all races in the desolate world were almost extinct, which also gave the human race a great space for survival and development.

In the long years, there were six saints in the human race, divided into Taoism, Buddhism, and Demon Religion, and the three religions of the human race.

During this period, the Heavenly Demons in the Extraterritorial World began to invade the Flood World, hoping to take it for themselves, and launched a war of aggression.

As early as the ancient period, the Heavenly Demon had invaded the Flood World, but at that time, the various races of the Flood World were at their peak under the leadership of the Lich and the Lich Clans, and the Heavenly Demons were driven out before they could set off a storm, and even the Demon Clan had been killed outside the territory under the leadership of the two Demon Emperors, and the Heavenly Demon Clan suffered heavy losses and almost wiped out the clan.

In the Middle Ages, the strength of the various races in the Flood World was far from being comparable to that of the primeval period, because of the Lich War of that year, the inheritance was lost a lot, which caused the Heavenly Demon Clan to make waves in the Flood World. During this period, another new force was born in the human race, namely the Three Emperors!

Three emperors appeared in the human race, each of which established a state to rule the human race, becoming an existence that could compete with the three religions, and thus the saints born in the human race changed from six to nine.

The nine saints led the human race to become the main combat force of the desolate world against the heavenly demons, and also became the leaders of the various races, it can be said that the human race has developed to the most glorious stage in this period, but the strength of the heavenly demons is extraordinary, and the desolate tribes and the heavenly demons also fought a decisive battle like the Lich War back then.

'Clash of the Gods'!

This battle almost killed the heavenly demons, and the hundred tribes of the flood and desolation kept their homes, but the combat power was also nine out of ten, and the twenty-four saints of the hundred tribes all fell, and this battle destroyed many middle thousand worlds and small thousand worlds, and finally only thirty-three middle thousand worlds and ninety-nine small thousand worlds remained.

After 12.96 million years in ancient times, the ancient era entered the real era of the end of the law, which is also the middle period, this period is not only the thinning of the vitality of heaven and earth, but also one of the reasons for the end of the law era.

During this period, there were no saints, and the quasi-saints were respected, among which the strongest was the five emperors of the human race, and the power of the five elements of the world's origin was peeped by the five emperors, and the five elements were practiced to control the power of the desolate world, become the overlord, and dominate the desolate world.

Under the leadership of the Five Emperors, the human race became the sole protagonist of the flood wilderness, and the other races retreated.

The Terrans have reached their peak in all aspects and are incomparably strong, but the Heavenly Demon Clan, after hundreds of years of recuperation, has invaded again, and this time the Terrans have become the absolute main force against the invasion of the Heavenly Demons. In this battle, the five emperors did not have the ability to kill the heavenly demons like the sages and almost wiped out the clan, so they could only prevent the heavenly demons from invading the desolate world by sealing the extraterritorial passage, and then worked together to eradicate the heavenly demons left in the desolate world.

After 3.6 million years in the Middle Ages, it withdrew from the stage of history.

"129,000 years have passed since the Great War."

Ao Li didn't simply talk about the deeds of the Five Emperors, because he didn't know very much, after all, he was not a person of that era, and Li Zhen didn't know much about the history of the desolate world, so Ao Li briefly described the history of the desolate world.

After Li Zhen learned about these things, his existing worldview completely collapsed.

Before, he knew that he was a frog at the bottom of a well when he retreated to the Nanping Domain, but today he realized that he was not even worthy of a frog at the bottom of a well.

In the past, Li Zhen was complacent about his achievements and opportunities, but compared with the sages, he was not worthy of lifting shoes, let alone lifting shoes, he was not qualified to compare with them.

"The Heavenly Demon is the greatest scourge that endangers the Flood World."

Li Zhen said with a straight face.

Ao Li nodded and agreed: "Not bad! Back then, I heard the elders of the clan say that the Heavenly Demon was the most terrifying race in the world, and there was no one. ”

"Why do they want to take over the Flood World?"

Li Zhen asked the doubts in his heart.

"Their world has been ruined by themselves, and they need a living world for them to survive."

"Can't we live in peace?"

Li Zhen said casually, but soon regretted asking this stupid question.

Ao Li smiled slightly and said, "The biggest original sin in this world is selfishness. ”

Li Zhen nodded, it was precisely because he thought of this that he regretted asking such a question.

Li Zhen immediately informed Ao Li about his encounter with the Heavenly Demon, more precisely, the Demon, and Ao Li was not nervous when he heard this.

"The passage from the extraterritorial world to the desolate world has been sealed, and there is nothing to fear if some demons stay in the desolate world."

Ao Li didn't care, because he knew that these were the descendants of the Heavenly Demons, not the pure-blooded Heavenly Demons, and only the pure-blooded Heavenly Demons were really a threat, but these demons couldn't be left alone, and Ao Li pondered about finding an opportunity to clean them up in the future.

The descendants of the Heavenly Demon can be used as nourishment for him to devour with gluttonous Dafa and restore his cultivation.

It didn't take long for Li Zhen to retreat and cultivate again, and this time Ao Li would help him directly open the sea aperture and promote to the True Law Realm.

········································

The palace master of Tianshou Palace suddenly came to Donghua City, the imperial capital of Huaguo.

Li Zhen is now in retreat and cultivating, and Li Zhen, the representative of Wanxian Pavilion and Zongren Mansion, was ceremoniously received, after all, the strength of the palace master of Tianshou Palace is in front of him, who dares to despise half a point, and even everyone has to look up to each other.

The palace master of Tianshou Palace was received by the elder of the great clan and Li Zhen's grandfather Zhou Qian.

"I don't know what happened to the palace master?!"

The other party will definitely not come to Donghua City for no reason.

"The lord of this palace is here to receive a message for help, and he has come to report to His Majesty."

"Oh?"

Zhou Qian and the elders of the big clan are all strange.

"Your Majesty's future queen has been forced to marry, and Your Majesty needs to hurry to the Taiping Domain to rescue her."
