? "The information you gave me last time was very helpful for my research, I have already developed the finished glasses, but I have left the laboratory when Aunt Connie told me just now that you came, so I can only bring the glasses to you tomorrow. Hai ** Na said with her hands on the desk.

"Oh, it's okay, I still have some things I need your help with, and it just so happens that you can bring it to the lab tomorrow, this is the drawing." As he spoke, Zhang Cheng took the drawing out of his pocket, walked to the desk, and handed it to Hai **Na.

Hai ** Na took the drawings, when her eyes swept over the complex graphics and data of the drawings, the eyes hidden behind the glasses actually flashed with a hot light, Hai ** Na almost grabbed the drawings, and then began to read the pages by herself, it seems that the content that makes Zhang Cheng's mind swell is very attractive to Hai ** Na.

Seeing that Hai ** Na was obsessed with the drawing, Zhang Cheng, who was ignored, felt a little embarrassed, and then he saw the coffee cup on the side, but when he picked up the coffee cup, he found that it was empty, and the boring Zhang Cheng had to stand there in a daze and wait for Hai ** Na to shift her attention from the drawing to herself.

Nearly 5 minutes have passed, and Hai ** Na has turned the drawings to the last page, but at this moment, the heat in her eyes turned into shock, and even a series of emotional changes, Zhang Cheng was a little puzzled, but when he took the drawings from He Chuli's hand, he was a little confused by the complex graphics and words on it, so he didn't have the content after that. What was the content that shocked Hai ** Na so much, and he had no way of knowing, but it was a pity that the drawings had already been ** in Hai ** Na's hands, so Zhang Cheng couldn't get it back.

"This document ......"

"Oh, this document is He Chuli, it was compiled by the ** child who came with me last time, including the λ-driver glasses information given to you last time, which is also the result of her research." Seeing that Hai ** Na finally reacted, Zhang Cheng hurriedly replied.

"Then she didn't come." Hai ** Na's expression is very complicated, but Zhang Cheng saw another emotion from it, that is, jealousy, it seems that no matter how wise **** is, the vanity in her bones cannot be erased, it is obvious that Hai ** Na has always had a very high sense of superiority over her IQ, but when she found that someone surpassed herself in this regard, and it was also ****, the most important thing is that she was at least 10 years younger than herself, although this feeling is not a blow, but it will also make Hai ** Na felt a little upset.

"Well, because there are other things to take care of, I'm the only one to come this time." Zhang Cheng felt a little depressed, because obviously Hai ** Na was more interested in He Chuli, and it seemed that the so-called "thirty-year-old widowed **** will reduce the resistance of 60% to different **" is completely nonsense, at least for a **** like Hai ** Na.

"Well, well, you come to me at this time tomorrow, and I'll give you the finished λ-driver glasses and the things on this drawing, by the way, let's have dinner here in the evening!"

Although Hai ** Na said so, but Zhang Cheng did not hear the sincerity of the invitation, so he politely rejected Hai ** Na's kindness, and left the villa, it seems that the 30-year-old widow **** in addition to the 60% reduction in the resistance to different **, the vigilance has also been improved, after all, a widow ** trying to keep the male ** is not very good to pass out, even in an open world like "Star Troopers".
