From the time Pangu created heaven and earth, and the primordial gods were born in response to the Heavenly Dao, it was known as the Primordial Era.

Regarding the existence of the primordial gods and their stories, Zhou Yin was actually not very clear. Not only him, but the people of his era were already very far from the time when the primordial gods existed. The continental chronicles were vague and ambiguous, with a few strokes that seemed to be but were not, making it impossible for later generations to clearly glimpse everything from that era.

According to legend, after the fall of primordial gods such as Nuwa, they were replaced by the immortal race, demon race, magic race, and the human race created by Nuwa.

With the fall of the primordial gods, the demon race, originally the ancestral race of Goddess Nuwa's clan, lost its glory. After experiencing a series of battles, it was completely defeated and lost its ruling position in the three realms, being driven down from the upper realm.

As time passed, the originally weak human race gradually rose. The immortal race ruled the upper realm and rarely set foot on the continent again. The scope of power on the primordial continent was redrawn, divided into the upper realm ruled by immortals, the lower realm occupied by humans, and the demon race ruling another realm, with each minding their own business.

Since then, although mortals in the lower realm still revered and worshipped immortals, and from time to time there were people who ascended to the upper realm through later cultivation, the lower realm began to use the calendar of human dynasties. As dynasties changed, the name of the dynasty was added before the year number to distinguish it.

The 40,000th year of the Primordial Era that Fei Lan spoke of was at least 60,000 years away from the era Zhou Yin was in.

Regarding that distant era, Zhou Yin knew very little. He only knew that he, along with Zhou Chen, had suddenly returned to 60,000 years ago through that cave, and it was very likely that they were about to witness the unfolding battle between immortals and demons.

Then where would Yu Nuo, who had taken the Vast Sea Star Chart, go?

Seeing the unusual expression on his face, Fei Lan asked in surprise, "What's the matter? Is there a problem?"

Zhou Yin said, "I heard that man just now say that you are an immortal from the upper realm?"

Fei Lan replied dryly, "Not anymore."

By this time, night had completely fallen. The sky of the Taichu Continent 600,000 years ago seemed to be even more clear, with a splendid galaxy spread out overhead, forming a vast and magnificent starry sky.

By the starlight, the surroundings could be seen clearly without illumination. They sat by the lake, the water as still as a mirror, clear and slightly cold like a large piece of colored glaze. Occasionally, a night breeze blew, stirring up flakes of fish-scale-like ripples. The night dew was light, and it was so quiet that not a wisp of dust could be raised.

"You are a rogue cultivator from the lower realm and have not yet glimpsed the Great Dao or entered the upper realm, so it's no wonder you are ignorant of many things. In fact, there are two kinds of immortals in the upper realm.

"One is the innate immortal, who is born as an immortal. The other is like you and me, originally of the human race, or spiritual beings, who later cultivate through chance and opportunity, thus becoming immortal. However, those who become immortals later are, after all, latecomers, and due to factors such as spiritual roots and aptitude, many are not as powerful as those who are innately immortal. So overall, innate immortals still make up the majority in the upper realm."

Although he explained it very euphemistically, Zhou Yin understood at once that this meant that there were also class divisions in the upper realm, and those of a higher class were often innate immortals.

"Kui Hao and I were originally good friends, but he is an innate immortal, and many of his ideas are bound to be at odds with mine. Now the upper realm is openly violating the ancient Nuwa Covenant by allying with the demon race to strike at the demon beast race, all for the sake of fighting for dominance in the upper realm."

Zhou Yin asked, "What is the Nuwa Covenant?"

Fei Lan was stunned. "You don't know about the Nuwa Covenant?"

Zhou Yin was very calm. "I have been cultivating in the deep mountains and am unaware of these changes in human affairs."

The two had already exchanged names and backgrounds, and Zhou Yin's cultivation level was obviously very low at a glance. Fei Lan did not suspect anything else and only sighed, leaning his head back against the tree trunk and beginning to recount.

The ancient grudges and entanglements were finally slowly revealed, allowing Zhou Yin to glimpse the ins and outs.

The ancient gods, such as Fuxi and Nuwa, had human heads and snake bodies, and most were of the demon beast race. Therefore, after the gods had successively fallen, Nuwa, as the last fallen deity, had left instructions for the demon beast race to rule the three realms, with the other races communicating and living in harmony with each other.

Due to Nuwa's prestige, the various parties were able to abide by this at first. However, human desires are insatiable, and as time passed, the successors of the demon beast race proved mediocre, and the immortal race gradually became dissatisfied, which was the source of the conflict.

At first, it was nothing more than small-scale conspiracies and mutual subversion, but later on, as there were many powerful members of the demon beast race, even the demon race became wary. Thus, the immortal and demon races joined forces and began to suppress the demon beast race.

The demon beast race had long been in a high position and indulged in pleasure, caught off guard and retreating step by step, to the point of being driven out of the upper realm and forced to wander the continent, scattering in all directions.

At that time, the human race had not yet risen and was ignored by the other three races. Faced with the situation of immortals and demons fighting to the death and the world changing color, they could only hide everywhere, avoiding it as if they could not avoid it enough.

The few among the human race with extraordinary aptitude who had entered the upper realm through later cultivation already considered themselves to be immortals and shared the same hatred as the upper realm. Those who were affected by the battles between immortals and demons were all common people.

That was a truly chaotic era.

Whether immortal, demon, or beast, all had great divine powers that could turn the universe upside down. Once they fought, it was bound to be a chaotic mess of moving mountains, filling seas, and covering the sky and earth.

Zhou Yin could even imagine that the scene he had just seen was only a drop in the ocean.

The war had reached this point and was becoming more and more intense, with almost all the races on the continent being drawn in, which was the situation he was seeing now.

The demon beast race was already in decline and showing signs of defeat. The upper realm was worried that powerful demon beasts would rise up again in the future and come back for revenge, so they wanted to exterminate them even more thoroughly, not even sparing the young beasts that had not yet grown up.

The furball had just followed Zhou Yin through that Sumeru Ring and returned to tens of thousands of years ago, only to be suddenly rushed to another place. If Fei Lan had not lent a timely hand, he might have already been turned into roast chicken wings.

Although Zhou Yin himself was not very interested in these grudges and enmities, this was very likely related to whether he could return or not, so he had been listening all along.

"Although I am a person of the upper realm, when I had not yet attained the Dao, I had received great kindness from the demon beast race. Although the immortals and demons are exterminating the demon beasts under the banner of the demon beast race being tyrannical and unrighteous, in fact, many of the demon beast race are just a bit unrestrained and free-spirited. Now, seeing that the entire race is about to be exterminated, it is in any case a matter that is detrimental to the Heavenly Dao."

"So there are quite a few people in the upper realm who, like me, can't stand it and secretly help the demon beast race. Who knew that not long ago, it was discovered by the upper realm, and I was expelled from the upper realm. It's just that I didn't expect that as soon as the other party saw this little demon beast, they would chase after it relentlessly."

Furball Zhou Chen was lying on Zhou Yin's shoulder, sleeping soundly, with saliva flowing down the corner of his mouth, soaking half of Zhou Yin's collar, looking cute and carefree, completely unaware of their conversation.

After hearing this, Zhou Yin was silent for a moment. "You're not telling the truth."

Fei Lan was stunned.

He said coldly, "From the situation just now, it can be seen that you were already being hunted by them long before you encountered Zhou Chen, otherwise you couldn't have been so heavily injured."

Fei Lan looked embarrassed, thought for a moment, and said with a bitter smile, "I'm sorry, it's not that I'm unwilling to say, but I have no choice. It's a major matter and cannot be easily disclosed."

Zhou Yin said, "I have no interest in your private affairs, but I don't want this to be related to the danger we are about to face."

Fei Lan sighed, "You're right, I shouldn't have implicated you. After resting for a while, let's go our separate ways."

But to his surprise, Zhou Yin shook his head. "I'll escort you a bit further. Although you are powerful, your spiritual consciousness is damaged and your vitality is greatly injured. If there are pursuers, cooperating with my talismans will give you a better chance of escape."

Fei Lan was a little confused by his meaning. "Then you just now..."

"You saved Zhou Chen, and I don't want to owe anyone a favor."

"Alright." Fei Lan was speechless. This is really a strange person, he thought.

Although he was injured now, he was still an immortal from the upper realm after all. This person's cultivation was very low, but was unlike other rogue cultivators who liked to ask him about the upper realm.

Zhou Yin did not look at his expression. He sat cross-legged under another tree, closed his eyes, and quietly nourished his spirit.

Zhou Chen was still lying on top of him, not even changing his sleeping posture, looking extremely at ease.
