Please Senior, Finish the Rest "Kirin 4000 words" (cont.)

[Editor's note: This chapter breaks our content rules, so it has been condensed into a summary of its story events.]

Kirin surprises William by revealing that she knows about a hidden feature nearby. Before he can ask what she is doing, she approaches a wall made of artificial rocks and begins searching its surface.

She finds a small red protrusion and presses it, triggering an unexpected change. The chapter ends before explaining what the mechanism does or how William reacts.
