122 Array Master, Sealing off space

"How big is the space that you see?" Feng Zhi Xing asked.

Sima You Yue looked around her, saying, "How big is it? I don't see an end, it's limitless."

Feng Zhi Xing's shock turned into gaping astonishment. He looked at Sima You Yue for a long time speechlessly.

After waiting for quite a long time, Feng Zhi Xing still had yet to reply her so Sima You Yue opened her eyes, asking puzzledly, "Master?"

Feng Zhi Xing took a breath, saying, "Alright, enough. You can retrieve your hand."

"Oh." Sima You Yue retrieved her hand, saying, "What was that?"

Feng Zhi Xing kept the box away, saying, "This was to test the level of one's perception of space."

"One's perception of space?

What was his point of testing her for this?

"Yup." Feng Zhi Xing said, "Didn't I say that I would teach you a skill? I'm not an Alchemist so I can't teach you alchemy. However, I can teach you about Arrays."
