"Wait a minute! And... the moisture in the dormitory building hallway!!"
Tian Bufan noncommittally: "You also observed the Gymnasium's performance on the layers level, right? The Gymnasium itself is a part of the 'City Wall' standing in the black ocean, blocking the Grey Mist Invasion..."
"...a part of it."
"The 'City Wall' developed a crack, and the occasional rainwater and mist that seeped through became the anomaly in the Gymnasium."
"That day when I was observing the old kerosene lamps inside the Gymnasium, I was actually searching for the existence of a 'fissure.' Unfortunately, I didn't have the chance to find it then; otherwise, I could guide you to repair the crack in advance."
"It wasn't until yesterday afternoon, when she held a 'banquet' in the Gymnasium, that I had the opportunity to guide you to discover the existence of the 'fissure' and attempt a repair."
"The good news is, you did not disappoint and successfully repaired the crack."
