Qin Yan had heard of it, but had never seen it. After all, when he came here, his second sister was not yet born. The last time he heard about it was from Tang Jinnan and Shou, so he became interested. His eyes behind the lens looked around at the faces of Qin Hongfei and Qin Qian, and finally passed by the one who looked a bit like himself, and fixed on Qin Qian, who was smiling as brightly as Qin Fei and making a V sign to the camera. He immediately knew who it was, and held his face and clicked the mouse to zoom in, "The squatting one is my second sister, right? She looks a bit short."

According to her age, she is fifteen years old.

So young?

Tang Jinnan leaned against the wall lazily and said, "Your face blindness is as serious as ever." They look so similar.

The first one looked at her with contempt, "What are you looking at? The one squatting is your cousin, and the one in the middle is your biological sister. You are both absolutely idiotic. The sister doesn't know the brother exists, and the brother doesn't know the sister exists."

Qin Yan was a little surprised, and his eyes moved up to the face of the girl in the middle, who didn't look like the older sister.

Neither of them smiled when looking at the camera, but Qin Fei and Qin Qianxiao looked similar, silly like biological sisters.

Retracting his gaze, he switched back to the video and said, "I don't know what's so strange about it."

"I've only heard of it but never seen it."

"When my second sister was born, I had been taken away for three years. We couldn't communicate at that time. We could only start communicating when she was twelve years old. The letter did mention family members." But for a sister he had never seen, even if she was his biological sister, Qin Yan had no feelings for her, so he didn't mention it.

After all, when Qin Fei was taken away, her mother was already pregnant.

If it wasn't a coincidence...

Tang Jinnan mentioned to the leader that his friend had run into his relatives and went to Qinhuai Street.

To be honest, Qin Yan found it difficult to pay attention to the existence of this second sister.

Not growing up together, not being raised together, it was already very difficult to maintain the family affection in the bones with the little memory before the age of two. It was unrealistic to say that there was much affection.

"However, is there anything special about my second sister that made you two mention her specifically?" Qin Yan supported his face with one hand, and was more interested in this.

"Don't you think there's something wrong?" Tang Jinnan reminded slowly, thinking that he was a little slow.

"..." Hearing him say this, Qin Yan stood up and stared at the two people in the video. The background was a wall. It can be imagined that the two were watching the video with their backs to others. Apart from that, there were no landmarks or anything special. What was special?

He stared at the only stone-painted exterior wall he could see. As he looked, he suddenly narrowed his eyes and finally found something wrong from the beginning of the video.

Tang Jinnan watched his expression change and said, "You are a little dull."

Qin Yan said nothing, thinking, if you stayed in the laboratory for two weeks without sleep, you would also be dull, "What the hell is this camera of yours?"

The high definition should be at least 300W, maybe more.

They are all good friends. Qin Yan did not ask Mr. Li for help in his research in this area, so naturally he had some one-sided understanding of computers.

Tang Jinnan calmly threw out a thunderbolt, "This is the special thing about your second sister."

"Her research and achievements in computers may not be inferior to those of Mr. Li."

The head said coldly, "Eliminate the possibility. If that old fox Mr. Li has not hidden anything, her sensitivity to computers is definitely better than that old liar."
