Whats the verse level of this cosmology?

And the next, extreme powercreep. To summarize what we already learned (see posts above)

-

Starfields are self contained, infinite universes
Starfields are infinite in numbers
Starfields themselves are closed off from each other
All star fields are born from a place called the Ancestral Domain

And of course the Ancestral Domain is higher tiered:

The World Energy here was indeed more abundant than any place in the Star Field, but it still wasn’t comparable to the Star Boundary. There was a large difference between the two. Moreover, Yang Kai could feel that the World Principles here weren’t as perfect as those of the Star Boundary.

In other words, Dao Source Realm was probably the limit in the Ancestral Domain while it was practically impossible for anyone to reach the Emperor Realm here.

The powercreep:

Presently, there was a board with a number of black and white stones on it in front of the old man called Wu Kuang. The strange aura wafting from the board was so intense that anyone who happened to see it would be shaken to the core.

After taking just one look at the board, Mei Jiu’er turned ashen and she thought that this old man must be too bored, which was why he decided to play the board game on his own. Moreover, it had even somehow turned into such an intense competition that the board itself was giving off an overwhelming aura.

The old man in the gazebo lifted his head to look at Yang Kai, then he burst into a fit of laughter as he called out, “Little brat, what are you doing here?”

...

“What do you think?” Yang Kai bent over and landed a slap on the board, which caused the black and white stones to be messed up.

Wu Kuang gazed at the board with a frown and sighed, “I was about to win. Why couldn’t you just talk it out with me instead of messing up my stones?” He sighed.

Before he could speak further, Yang Kai directly turned the board over. At that instant, all the stones were hoisted into the air upon impact.

Wu Kuang said with a smile, “Did you know how many people you’re about to kill by doing that?”

...

It was then Yang Kai snorted and took a seat across from Wu Kuang before he carefully put the stones back on the board. He didn’t intend to put them back in their original spots. Thus, he just arranged them properly.

Then, he checked on those stones, and upon making sure that they were fine, he let out a long sigh.

Mei Jiu’er didn’t understand why Yang Kai cared so much about these stones, so out of curiosity, she sent her Divine Sense towards the board and instantly fell into a dazed state as she was rooted to the spot. It was as though her Soul had been sucked out of her, and she had become a living corpse.

All of a sudden, a gentle force engulfed her, which caused her to come to her senses. Her pretty face had turned pale as she said in shock, “Senior, the board and the stones…”

Rather than a board, what was before her was an entire Star Field, and the stones were also not what they seemed to be as they were clearly whole Stars.

This amiable-looking old man with the demeanour of an immortal was battling against himself using the Star Field as a board and the Stars as pieces.

It was then she understood what the old man actually meant. All the stones were real Stars, and trillions of people lived on these Stars. By flipping the board over, Yang Kai had practically turned this Star Field upside down. If the stones really fell to the ground, countless lives would have been lost.

Yang Kai bowed his head and pointed at the board, “What is this?”

Wu Kuang looked away as he was meticulously probing Yang Kai’s body. Without even thinking, he replied, “Blood Sun Star Field.”

Even though Yang Kai already had a speculation, he still gasped when Wu Kuang admitted it, “You’ve refined a Star Field into such a thing?”

He didn’t know where Blood Sun Star Field was, nor had he heard of it before, but apparently, just like Heng Luo Star Field, it was also a Lower Star Field; however, it had become a board game that was right in front of him now.

Wu Kuang replied with a grin, “What’s so strange about it? There are many more in the sky.”

Yang Kai looked up as his pupils contracted because nebulas of different sizes were hovering in the sky above him. Some of them were as small as a dustpan while the bigger ones were the size of a basin. There was some distance between them as they were not compatible. If Wu Kuang hadn’t pointed it out, Yang Kai would’ve just thought that these nebulas looked a little odd even if he happened to see them. Upon closer look now though, he realised that every nebula was a separate Star Field.

Staring fixedly at them, Yang Kai could see that the Cultivation Stars were as small as dust, on which billions of people lived.

However, just like the stones on the board, these people were not aware of the situation they were in as they went about their daily lives.

People with high enough cultiavation can refine these infinite starfields and all of its individual cultivation stars into a checkers board, a nebula, pieces of dust...all without the inhabitants of the starfields noticing what has happened to them.

And the powecreep continues: Not only can these individual starfields, which all stem from the OG world, the Ancestral Domain, be refined in such a way. The Higher plane of the Ancestral Domain itself was turned into just a garden for the cultivators pleasure:

“Aren’t you supposed to be in the Ancestral Domain? Why are you here? Where’s this place?” Yang Kai wasn’t willing to dwell on the topic of Demon Qi, he just wanted to find out what Wu Kuang was doing.

“We are in the Ancestral Domain,” Wu Kuang replied.

“Nonsense!” Yang Kai rebuked. It wasn’t like he hadn’t been to the Ancestral Domain, so he knew what the place looked like; however, after giving it a thought, he realised that, since this old fart was able to refine Star Fields into boards and nebulas, it wasn’t so unthinkable that he could turn the Ancestral Domain into a garden.

Someone who achieves this, can possible create a great world (Great World is another term for "Universe World"), through merging all infinite star fields back with the origin world:

After a moment of silence, Yang Kai asked with a frown, “Is this a Sealed World?”

Wu Kuang shook his head with a smile, “It’s a Great World.”

In an instant, Yang Kai turned pale and stared at him in shock, but he knew that Wu Kuang wasn’t lying. Mei Jiu’er just thought that the World Energy in this place was ample, but she hadn’t realised that the World Principles in this place were also incredibly strong.

Just like the Star Boundary and the Demon Realm, it was also a Great World. Even though this place was no match for the former, it wasn’t too far off.

“That’s right. The Ancestral Domain is the origin of all Lower Star Fields. By refining the Ancestral Domain, it significantly reduced the effort this King needed to exert in order to achieve my goal.”

Following that, he nodded gently and asked, “Does he have to devour every single Lower Star Field and integrate them with the Ancestral Domain?”

Duan Hong Chen replied, “You’re fairly strong now, so I’m sure you can see that the Ancestral Domain has gone through some changes. The old fart isn’t wrong to say that it is a Great World. According to our estimation, if we manage to integrate all the Lower Star Fields, the Ancestral Domain will indeed become a Great World. By then, the Ancestral Domain will become a Plane that is an equal match for the Star Boundary. You have to understand that every single Lower Star Field was separated from the Ancestral Domain in the past. What we’re doing is just amalgamating them, returning them to their original state. It would be best if we could integrate all the Star Fields as no one can tell what the outcome will be if one or two are missing.”

And all of this STILL happens inside the first Great World / Universe World. Not a single step has been taken outside.

Scaling wise this pairs the traditional estimate of strenght of being Multiversal+ as well as the newer / alternative approach of higher dimensionality.

What tiering system would we apply here and what would be a good baseline?
