"Dad!" Sangsang wiped away her tears and spoke firmly, "I'll go, I'll go find her for you, okay? Where is she?"
Xu's father instantly fell silent. After struggling for a moment, he lost all strength and sank powerless onto the bed. "Sangsang, the key is in my bag. Take the key, go to my lab, and in the right-hand third drawer under the experiment table, there's a wooden box. Drink what's inside the box, and focus—focus really hard. You must think carefully… April 12, 1982, Sunday, the A University Library…"
Sangsang solemnly locked the date in her memory: "April 12, 1982, Sunday, A University Library…"
"Take this photograph. Remember, it's April 12, 1982…" Xu's father's voice grew weaker and weaker. "When you meet Youmei, tell her for me… I've always been waiting for her, and I'll find her…"
"Alright, I understand." Sangsang nodded repeatedly, promising him.
