Unlike the supernatural power users I've encountered before, I can't sense a high-quality soul aura or any mana fluctuations from Zhuang Cheng. He seems like an ordinary human you could find anywhere.
This level of response is not enough to confirm that Zhuang Cheng is just an ordinary person. There are many who excel at concealing their oddity, and perhaps Zhuang Cheng's power is one of them.
I plan to send a Shadow Clone to probe into Zhuang Cheng, and at the same time, I must investigate the 15th-floor room.
In fact, I don't believe the cave on the 15th floor is the entrance to the future but more likely an entrance to a Different Space. Its manifestation is completely different from the expected effects of a ritual array, which probably resulted from a malfunction in activating the array.
But even a malfunction meant it was activated. Zhu Shi would neutralize the ritual array the next day, so I needed to understand why it was activated before then.
