"Lin Kexin?" Seongnam was also taken aback.

Chengnan took the letter from Zhang Mei's hand in surprise, and was also startled when he saw it, and the envelope really had three words written on it.

"It's a strange letter, it has only the signature of the writer and not the recipient." Seongnam looked at the few words on the envelope and said strangely. Zhang Mei on the side was also puzzled, but when she thought that Lin Kexin had intellectual problems, Zhang Mei was relieved.

"Take it apart?" Seongnam turned back to Zhang Meishen and begged for it.

"Yes." Zhang Mei naturally wanted to know the content of the letter, and this was also a very important piece of content, so Zhang Mei naturally didn't want to miss it.

Chengnan lowered his head and opened the letter, just looked at the beginning of Chengnan and suddenly exclaimed, it turned out that Chengnan had just opened the envelope, and the two crooked words of the sister at the beginning of the letter came into Chengnan's eyes.

Zhang Mei on the side saw that Chengnan was suddenly so excited, and suddenly wondered: "What's wrong?" ”

"Haha!" Cheng Nan glanced at the contents of the letter casually, and suddenly laughed: "I really guessed correctly." ”

"You guessed something right?" Zhang Mei saw that Chengnan didn't answer herself, but she suddenly laughed to herself and asked.

"Look at this." Chengnan was not in a hurry to explain, but handed the letter in his hand to Zhang Mei's eyes and said.

Zhang Mei took the letter from Chengnan's hand suspiciously, and when Zhang Mei read the whole letter, she was also surprised, and wondered: "This... What is possible....this Lin Kexin also has a sister? ”

"Very likely." Seongnam looked at the channel in Zhang Mei's hand.

Zhang Mei's heart tightened, if this Lin Kexin really has a sister, then the recent "ghosts" of her own group of people can be explained!

Although there are some clues now, there are still many questions, Zhang Mei frowned and looked at the letter in her hand: "Lin Kexin is just a mentally handicapped child, whether the sister in this letter is really her sister is still uncertain, let's just say that this letter is really her sister, this letter only has the word sister from beginning to end, but it does not involve the name or address of this so-called sister in the slightest, so what can we check?" ”

This is indeed a problem, Cheng Nan lowered his head and thought about it: "I read the content of this letter just now, it shouldn't be the first time they have contacted each other, you may be able to find the letter written by the other party to Lin Kexin if you look for it." ”

Zhang Mei shook her head when she heard this: "At the time of Lin Kexin's death, we had already investigated all her things and found nothing of value. ”
