"This world has now merged with the worlds of our human race, as well as the worlds of all races, alien races, and demon races. You have merged with the Dao of this world, and being human, you can, to a certain extent, borrow the power of this world and our world within the current human territory."

"But this place is the dividing line between the human race and the various foreign races at this time. It contains the complexity of the world. The human race's ancestral star cannot directly affect this place, so it is normal for your cultivation to decline here."

Li Chengfeng explained.

Before he could finish speaking, a large bell rang out on the walls of Chang'an, and countless demon slayers emerged from the void, standing on the walls with fierce expressions.

At the same time, countless black mists mixed with eerie blood-red light surged towards the front of the city wall, obscuring the sky in front of the city wall in a short while.

The ensuing terrifying pressure swept in like a torrential downpour, instantly activating a series of formations laid out on the city walls.

Whoosh!

With a flick of his robe, Li Chengfeng created a transparent light shield that enveloped Su Bai.

"Let's talk as we walk. You can ask me any questions you may have."

Su Bai nodded.

The two then began to wander around the city wall.

The layout of this city wall is in the ancient style, and the materials used are all the stone bricks that Su Bai saw at the Ancient Wolf Demon King's place.

"Brother Li! Su Bai!"

"Brother Li! Su Bai!"

"Brother Li! Su Bai!"

"..."

Along the way, people who were fighting off the enemies ahead also took a moment to greet the two.

The martial arts and spells they used were at least A-level, suggesting that Li Chengfeng and his group had taught them many powerful martial arts techniques after arriving here.

However, during this time, Su Bai also discovered that among the powerful individuals participating in the resistance, there were not only humans, but also some races similar to demons.

Seemingly sensing Su Bai's confusion, Li Chengfeng explained, "Besides our human race, the Spirit Race is also among the races participating in the resistance."

"The Spirit Race?"

"Yes, the Spirit Clan. The Spirit Fox Royal Family, which participated in your resistance against the Demon Clan, is one of the Spirit Clan."

"Since you understand the ancient times, you should know that there were ten royal families among the demon race. The current spirit race is one of the former ten royal families of the demon race."

"There are two spirit races that are united with our human race: the Spirit Fox Royal Clan and the Spirit Tiger Royal Clan. There are also two other spirit races: the Spirit Dragon Royal Clan and the Spirit Phoenix Royal Clan. Previously, they were also on our side, but now, both of them have followed Fuxi, Nuwa, Pangu and their group to the Celestial Planetary Domain, also known as the Celestial Realm."

"Of the ten demon clans, apart from the four spirit clans and the Zhulong royal family, the Divine Crow royal family, and the Ape Demon royal family that remained in this world, the other three royal families also went to the Heavenly Path Realm. This is why you did not encounter any other demon royal families during this great battle."

Li Chengfeng explained.

"Originally, we planned that this large-scale invasion of the human race's ancestral star would not only resolve the current predicament of the human race, but also allow the human race to continue to pass on its foundation accumulated over tens of thousands of years. However, we did not expect that the alien races from beyond the realm, in alliance with all races, and the demon race saw through our plan and made a powerful invasion. Our human race was also forced to move the former star field battlefield to the territory of the human race's ancestral star."

“Look, this creature, which is neither a demon nor any of the myriad races, and has no human form, but seems to be a wisp of nothingness, is the alien race.”

Li Chengfeng pointed to a mass of energy radiating the powerful aura of the Radiant Realm and said.

Su Bai nodded and glanced at the front of the city wall. The terrifying aura was like a fierce wave, which instantly shocked him, who had no cultivation at the moment, and made his face turn pale.

But his eyes were calm. Even though the battle was fierce, it was still quite different from the battle three years ago.

"What realms and lineages lie beyond the Supreme Realm?"

Upon hearing this, a hint of excitement flashed across Li Chengfeng's brows, and he hurriedly asked, "Have you met your father, the Emperor Chengtian?"

Su Bai nodded.

Upon receiving his confirmation, Li Chengfeng breathed a sigh of relief and explained, "Experts above the Supreme Realm are collectively called Realm Realms. There are nine Realm Realms in total. According to the rules of our human race, those below the third Realm Realm are called the Beginning Realm Realm, those above the third Realm but below the sixth Realm Realm are called the Unifying Realm Realm, and those from the seventh to the ninth Realm are called the Ancestral Realm Realm. Above that is the Emperor Realm. The previous Emperor Chengtian, and even the three human emperors Nuwa, Pangu, and Fuxi, all went to the Celestial Planetary Domain with this level of cultivation."

"As for what goes beyond that, I don't know. The Celestial Planetary Domain is far from here, beyond the comprehension of us realm experts."

As they were talking.

Li Chengfeng flipped his wrist, and six different colored, dreamlike worlds appeared in his hand, emanating terrifying and chilling sword energy.

"The concept of a Realm expert is easy to understand. Controlling one world is one Realm level. If I control six worlds, I would be a Realm Level Six expert, which is also the Realm Ruler."

"It is said that by mastering nine worlds, one can condense the Heart of the World, unifying all the worlds under one's control into a single world that can truly give birth to life, possess reincarnation, and be blessed by the power of cause and effect."

Speaking of which...

Li Chengfeng let out a long sigh.

"It's also our fault for not providing timely support. If we had been faster, you wouldn't have had to give up your supreme path that would allow you to directly cross the boundary and ascend to the Great Emperor realm."

As soon as he finished speaking, Li Chengfeng turned his head, as if trying to see some emotion on the face of the white-haired boy, but to his surprise, the white-haired boy remained calm throughout.

It was as if losing this path to heaven, which only required him to obtain the Heart of the World to become an emperor, was a trivial matter to him.
