"By the way, there's something I need to tell you." After chattering on for a while, the Tree Spirit suddenly adopted a more serious tone.
"I've conveyed your speculation about the ruins' gate to Rhein. Rhein agrees with your thoughts and plans to enter the central passage within the next two days to check if the owner of the leather shoes, who appeared there previously, is still present." Tree Spirit paused for a moment: "If it is confirmed that they are not there, I will contact you immediately to see if the door is as you speculated."
Angel nodded: "Okay."
"You should prepare in advance, just like when you repaired the magic pattern on the gate, to avoid any issues at the time. After all, behind that door lies the true interior of the ruins, and the longer you stay there, the more variables there will be." Tree Spirit advised.
"I understand." Angel said solemnly.
