"Mom, haven't you slept yet?" Qin Yu put down the water cup and looked at Qin Peihan with some surprise.

"Well, I went for a walk, and I just came back." Qin Peihan walked towards her.

Qin Yu opened his mouth: "It's so late, are you still going out for a walk?" ”

"I can't sleep, I'm too obsessed with thinking about your two siblings." Qin Peihan laughed self-deprecatingly.

"I'm sorry Mom, I'm worried about you." Qin Yu apologized to her guiltily.

"Xiao Yu, in fact, my mother has a deep understanding of what you have encountered," Qin Peihan pulled her to sit down, "Originally, you are about to graduate, so it stands to reason that I shouldn't care about you so much." But Xiaoyu, do you know why your mother is so opposed to you intervening in your curiosity? ”

Qin Yu shook his head: "I don't know." ”

"Because that's how your biological father was killed. So Xiaoyu, mom can't just watch you in the whirlpool, but you have to stand by and do nothing. Qin Peihan held her hand tightly and said seriously.

"My biological father was killed? But you didn't mean it...... So you came to my room last night, right? It's not my dream! Qin Yu instantly stammered with excitement.

Qin Peihan closed his eyes, as if he was seriously recalling the past.

At that time, there was a horrific case in Jiangcheng, and many police officers rushed to it, but they could not find an answer. All I remember is that it was a cloudy day, and the sea was full of strange dead birds. And your father also disappeared without a trace in that case. ”

"So Dad just disappeared, right?" Qin Yu seemed to see a glimmer of hope.

Qin Peihan shook his head slowly: "The investigators at the time said that your father fell into the sea by mistake. But how could he have been a tower keeper for so many years? But the police started a three-day and two-night search, and the technology of that era was not as developed as it is now, and after a few rounds of searching, there was still no result, and your father did not come back. ”

"He loves the sea so much, and he loves the work of guarding the tower so much, if he just disappears and leaves, then he will definitely come back. But over the years, I have entrusted my friends in Jiangcheng to help me inquire several times, but there is no news of your father. Come to think of it, he must have returned to the sea like the birds, right? Qin Peihan said, and took out a newspaper clipping with a sense of age from his pocket, "This is the record of that time, I suddenly remembered it tonight, so I took it out for a walk, thinking about whether I could recall any key information." ”

Seeing this, Qin Yu immediately carefully took the newspaper clippings: "Is this Jiangcheng's 'Lighthouse Blue Bird Case'?" ”

The lighthouse bluebird case occurred in the 90s of the last century, and it is said that there was an unprecedented heavy snowfall in Jiangcheng, which had not snowed for a long time. Several bluebirds escaped the ravages of the blizzard, but they did not escape the catastrophe. Although local police officers have tried their best to investigate the truth about Bluebird's death, the situation is still unclear.

And this large-scale bluebird death phenomenon is also a tragic situation that the locals have not seen for decades.

"Yes, because the dead birds are all verdant green, they are collectively called 'blue birds' for the sake of people's records. And your father, on the day of the crime, received a letter from an unknown source. I went to bring him food, and I heard him mention it by chance. But we all thought it might be someone's prank, so we didn't care. Because in that letter, only one word was written. Qin Peihan said this, and stopped specially.

When Qin Yu heard this, his breathing instantly stagnated.

She seems to ...... Guess what the word is.
