“Okay,” Ning said, patiently listening to the explanation of the system.

Ning frowned a little. He could see what the system was trying to say. Before he could ask something, the system continued.

“When in fact the sphere is already as large as it can be,” Ning said.

“He’s already living on the side part of the surface of the universe,” Ning said, his eyes growing slightly wide as he started understanding what the system was trying to say.

“We have a Myroptoid, with me a 3 Dimensional human living on the inner surface of it,” Ning said. “I perceive the world in 3 Dimensions, but what it truly is is a 4-dimensional universe.”

“Right…” Ning said, feeling a little shocked about it all. He knew he had questions, but it took some time to formulate them. He tried imagining the 4D Myroptoid, but his mind simply wasn’t capable of it.

“Can you tell me what a Myroptoid is supposed to look like?” Ning asked. “I can’t imagine the fourth dimension at all.”

A small piece of knowledge appeared in Ning’s head and he viewed it. As he did, his face changed to a bizarre one.

“What… am I looking at?” he couldn’t help but ask.

“Yeah, but… what am I looking at? I can’t see any visible shape at all,” he said. It was something so weird and new that he didn’t even understand the piece of information he had just bought.

The bizarre shape took his attention away for a while before he thought of another question to ask.

“My inner world. Is it this shape as well?” he asked.

“Hmm? What property?” he asked.

“Loop… back?” Ning thought for a moment in surprise. “Is that why it loops back?”

In his inner world, when one kept flying to the edge of the size of the world, one would find themselves suddenly turned around, coming back from the other direction.

He was never certain why it worked, and System had only told him that it was how it worked. Today, he finally received the answer.

“Wait,” he paused as one last thing didn’t make sense. “If things loop back in my inner world, then… shouldn’t light loopback as well? How come I don’t see the sun in the night sky, glowing bright like stars.”

“Huh?” he exclaimed at the sudden knowledge. “Wait, light travels in the fourth dimension as well?”

“What does that have to do with light?” Ning asked curiously.

“And the boundary allows for all light and space to leave it?” he asked.
