"I think I know how!"
While the others were thinking about how to get inside, Lumine clapped her hands, having thought of something.
"What is it?"
Everyone turned to look at Lumine. As expected of the Traveler... she had thought of a solution so quickly. That was probably why that shrine maiden had entrusted the matter to her!
"Wasn't there a Seelie when we came in earlier?"
Lumine gave them a reminder.
When they had jumped down from the ancient well, they had spotted a Seelie in one corner. They simply had not paid it any attention before.
"Does it have something to do with the Seelie?"
"Possibly! If there were no way into the barrier, that shrine maiden wouldn't have given me the task. There must be some way in. No matter what, let's go back and try it first!"
Lumine thought it was highly likely. Whether it was a mechanism or a barrier, there had to be a way to solve it. There was no such thing as a mechanism that was an absolute dead end—this was experience Lumine had gained in Teyvat.
When Lumine led them back to where they had started, the Seelie was indeed still floating there.
The Traveler skillfully jumped in front of it. As if it sensed Lumine's presence, it proactively led her in a certain direction.
So, the Seelies of Teyvat all seemed to have some sort of connection with Lumine!
Led by the Seelie, they took several twists and turns... until it entered a pillar in a very hidden corner. The dirt on the ground split apart, revealing a chest.
Besides that... the soil nearby began to crack as well, and a Thunder Sakura emerged.
"This..."
Looking at the changes before them, not to mention Kujou Sara, even Mei was stunned!
