My disciple's cultivation returns ten thousand times, so I have to be invincible.

Yu Weichen also sighed: "But to be able to shatter the sky curtain, this person's strength is extraordinary! I'm afraid only those old guys who have sealed themselves in the first heaven can have such means."

"Many of those beings have been sealed away in the lower realms for countless years. Their mental states are somewhat unstable, and some even have strange tempers. Thank you for your hard work, all of you."

The two sides chatted for a few more words, and Yu Weichen said, "The three of you still have a mission to complete. Repairing the sky curtain is of great importance. I also need to take young friend Zhong to the upper realm to meet the Immortal Lord. I will not disturb you any further. Please open the sky curtain and let me pass."

The guardian's face darkened upon hearing this, and he released the formation: "Why are you still opening the sky curtain? There's such a big hole. Just go through it."

Yu Weichen's face twitched as well, feeling quite embarrassed.

Another guardian gnashed his teeth and said, "If I find that damned bastard, I will definitely... definitely report him to the Immortal Lord and punish him severely."

Zhong Qing nodded and said, "If I come across such an unreasonable person in the future, I will definitely help the three of you teach him a lesson."

Upon hearing this, the Guardian Body also felt quite favorable towards Zhong Qing and said, "Young people are kind-hearted, but you are young and your cultivation is still shallow. That person's strength is unfathomable, so you must be careful if you really meet him."

Zhong Qing nodded and said, "Thank you all for the reminder. I'll remember it."

After watching the two people leave through the sky, the three guardians sighed and continued to work hard.

Zhong Qing and the other two thus entered the third heaven.

Putting aside what just happened, Yu Weichen smiled and said, "Little friend Zhong, this is your first time in the upper realm, and you are not familiar with the conditions of the various heavens. This is a good opportunity for me to introduce them to you."

Zhong Qing nodded and clasped his fists: "In that case, I'll trouble you, Brother Yu."

The two continued to move towards the sky.

Although he did not stay in this third heaven for long, Zhong Qing could feel from a quick glance that this place also had endless mountains and rivers, and was filled with the breath of many living beings.

However, among these countless living beings, he did not sense any human breath, but instead a demonic aura rising to the sky. He thought he had entered the demon territory of Xuanyu again.

Yu Weichen smiled and said, "Did you feel it, little friend Zhong?"

"The environment of the Third Heaven is not much different from that of the Second Heaven, but the difference lies in the inhabitants."

"The First and Second Heavens are where the main lineage of the human race who have not yet achieved immortality resides."

"And the main body of the third and fourth heavens is the demon race."

"Here, humans are a very small minority."

Zhong Qing finally understood. No wonder he didn't sense any human presence. It turned out that this was the demon clan's territory.

"Hmm... Actually, the demon race is the name given to the human race in the lower realm. For True Immortals like us in the Immortal Alliance, using this name is not appropriate."

"To be precise, it should be the beast tribe."

"Whether it's a demon or a devil, they all ultimately originate from beasts. Regardless of whether they're ferocious beasts, spiritual beasts, demon beasts, or immortal beasts, they all have the word 'beast' in their DNA."

"In fact, the human race was originally part of the beast race. The human race and the beast race were collectively known as the Ten Thousand Races. However, in ancient times, sages such as the Great Emperor and the Holy King rose up to educate the people, freeing us humans from ignorance and the habit of eating raw meat and drinking blood. Only then did the distinction between humans and beasts emerge."

"The biggest difference between us humans is that all of us, regardless of whether we are immortal or mortal, old or young, are born with spiritual intelligence. However, among the beastmen, with the exception of a few like dragons and phoenixes, most races only have a few who have awakened their spiritual intelligence and formed settlements."

"Thus, the number of humans who can cultivate and embark on the path to immortality far exceeds that of any other race. This is also the reason why the ancient human race was able to stand out and become the strongest race."

"But the human race and the beast race have been mortal enemies since ancient times, fighting endlessly. Even under the oppression of the catastrophe, they were forced to unite their forces. However, without external enemies, it is still difficult for them to coexist peacefully."

"So when all the races migrated to the Nine Heavens, they took this into consideration and decided to separate the demons."

"In addition to the First Heaven, a considerable number of beastmen were left behind during the migration due to being contaminated by the curse. The majority of them are in the Third Heaven and the Fourth Heaven."

Zhong Qing nodded: "I see."

No wonder there are so many monster groups in the first heaven. He can hardly see the existence of monster groups in the second heaven.

It turns out they are all in the third and fourth heavens.

The demons and humans in the first heaven...are actually cursed and abandoned.

"It is also to prevent conflict between the human race and the beastman race, so the second and third heavens will also close the sky curtains to cut off communication between the two sides."

Yu Weichen said, "As for the third heaven and above, although the sky curtain still exists, it is not closed. As long as you have sufficient cultivation, you can pass through it."

After a few words, the two had reached the sky between the third and fourth heavens. Sure enough, although there was a barrier here, it was not strong. In Zhong Qing's perception, he estimated that anyone with the cultivation level of a quasi-emperor could pass through it at will.

While crossing, they caught a glimpse of a secret place among the clouds from afar. There was a figure sitting in it, looking over.

"That is the guardian of the Three Heavens."

Yu Weichen said as he nodded to the man.

The figure glanced at Zhong Qing and nodded in response, but the two sides did not communicate.

"The guardians here are actually just here for routine duty. As long as there's no major problem, they won't stop us."

As they were talking, the two of them arrived at the fourth heaven.

This place is still the territory of the demon clan, or the beast clan.

However, the beast aura that Zhong Qing sensed here was much stronger than that in the third heaven.

Yu Weichen seemed to know what Zhong Qing was thinking and smiled slightly.

"Don't look at me as a human race that likes red tape and pays attention to the distinction between high and low."

"The beastmen are divided into countless races. They believe in the survival of the fittest and only distinguish between the strong and the weak. The gap between the upper and lower levels is actually much greater than that of our human race."

"The beastmen who can live in the Fourth Heaven are the most powerful among all the races."
