The instrument room is on the third floor, it is a dust-free and sterile room, she is familiar with putting on disposable protective clothing at the door, putting on shoe covers, wearing a mask, and walking in.

The entire instrument room was arranged with a metallic feeling, as if he had stepped into the future, Ye Shichao sat on a round stool, staring at the data on the computer with all his body.

Xin Pet walked over, trying not to disturb him, but as soon as he walked up to him, he heard him ask, "It's so late, why are you doing here if you don't go home?"

When he asked this, he didn't look back, his eyes were always on the computer, and he didn't know how he saw her.

"My brother asked me to see if there was anything new to be discovered here. Xin Pet touched his nose, a little weak.

Ye Shichao raised her head at this time, and her pretty face was reflected in the dark pupils, "I'm comparing the luminous insects found on the corpse with the luminous insects taken from the Dance of Light, and the results will be available in the second half of the night."

"So, are you planning to stay up late?" Xin Pet looked at the shadows under his eyes, a little distressed, "Don't be in such a hurry, my brother doesn't have to ask you to give a quick result." ”

Ye Shichao lowered his eyelids, "In addition to DNA, there is another thing that I care about very much, if I don't verify it clearly, I will be sleepless all night, even if I go home, I just change places to work, it is better to stay here." ”

Hearing him say this, Xin Pet remembered that he was still at the police station and said to Singer, "There is something I care about very much, if you don't confirm it clearly, you will be driven crazy". suddenly felt that the two of them were really similar in terms of truthfulness.

Thinking of this, Xin Pet didn't want to go home at all, so he simply pulled a round swivel chair over and sat next to Ye Shichao, "When I was in school before, I only saw forensic science students extract human DNA, and I have always been very curious about how your laboratory extracts DAN from insects, can you show me how you work?" ”

"It's a long time, unless you're planning to stay up late. Ye Shichao looked at her eyes flashing with little stars, a little unbearable to refuse her, and his voice was much softer, "Let's wait for the daytime to come and see." This is a biotechnology laboratory, focusing on insect research and insect biomimetic invention, this kind of DAN extraction is the most basic experimental project, you can see it any day. ”

"Right now, today, I want to see it. She looked at him with her cheeks raised, her voice a little coquettish, "Anyway, it's just the two of us, it's okay to stay up late." ”

Ye Shichao looked at her pretty face, he didn't know what he thought, his cheeks were slightly red, and he couldn't seem to find a reason to drive her away again, so he could only get up helplessly, "Follow me." ”

Xin Pet enjoys his compromise very much, and for a strict person like him, compromise means that he cares. He cared about her.

This made Xin Pet a little proud, and a little fluttering, got up and followed him, and reached out to grab the corner of his clothes, Ye Shichao glanced back at her, and probably felt that there was no one in the laboratory at this time, so he simply signed her hand.

Xin Pet was so proudly led by him to the sample room on the first floor, found the sample box marked with the date and code, opened it, and explained it seriously.

"Take a sample from a single individual, place it in a 1.5 ml Eppendorf tube, and rinse it twice with sterile water...... he said, wearing disposable rubber gloves on his hands, his eyes are serious, his brows are slightly frowned, every movement is meticulous, and the contour of his chin looks as good as a knife in the white light.

Xin Pet looked at him without blinking, and he didn't know whether to look at his hand movements or his face for a while, after all, both of them wanted to see it too much, so they could only keep moving their eyes, very busy.

"Then add TE buffer, cut it with sterilized ophthalmic scissors, add the same amount of buffer, and then put it in a 37 degree Celsius water bath for 5h, then take it out, centrifuge it with 8000~10000r/min for 5min, and discard the clear liquid ......" Speaking of this, he has already done the step of the water bath, to wait for five hours, he sat down, and slowly said the next steps, a total of seven steps, after saying that Xin Pet was a little confused, just listen to him continue," The biggest feature of this method is that it is easy to operate, and does not require liquid nitrogen freezing or grinding, which avoids cross-contamination when extracting DNA from multiple samples. If you are interested, you can try it yourself, you have to catch it yourself without samples, the samples I have here are recorded, and you can't use them casually. ”

Xin Pet was eager to try, and was about to go to his vegetable patch to catch insects, when he suddenly remembered that it was winter, "This weather, is your vegetable patch no longer planted? ”

"There's a greenhouse behind the lab, and the climate is never an issue. Ye Shichao said, taking off his gloves.

"Forget it, don't spoil your equipment and reagents. Xin Pet waved his hand, thinking that he had taken great pains to build a greenhouse in order to grow vegetables for the insects to eat, and he felt funny. I remembered the first time I went to his vegetable field and delivered fertilizer to the mute old farmer, told her, "He said you are beautiful", the smile became thicker, and asked, "Does the dumb uncle who delivered fertilizer still come to deliver fertilizer?"

"Once a month and never missed an appointment. The dumb man is very responsible. Ye Shichao got up as he spoke, his handsome face was slightly tired, "It's going to wait five hours, I'm going to go to the office to sleep for a while, you can go home early." ”

Xin Pet nodded and laughed, with some flattery and some cunning in his smile, "If you are free tomorrow, can you accompany me to the Dance of Light again?"

"Available. Ye Shichao didn't ask her what she was doing, so she agreed, her dark eyes looked at the smile on her face, and even her voice softened, "Just take it as a thank you gift for accompanying me to work overtime." ”

Maybe it was the gentle voice that bewitched Xin Pet, or maybe he was too tired, Xin Pet suddenly didn't want to go home, so he had to inch in and say: "Tomorrow I want to check things before the Dance of Light opens, it will be there before seven o'clock, and now it's almost twelve o'clock, and then drive home, plus the time to pick you up tomorrow morning, it will be an hour to come back and forth...... Why don't I sleep here too, so it saves time. ”

"I only have one couch in my office. Ye Shichao showed a look of embarrassment on his handsome face, and thought for a moment, "Let's go to my house, my house is more spacious." ”

As he spoke, he picked up the key and took off his white coat, revealing a dark gray sweater inside, with a lifelike bee rusted on the sweater, which was a sign of "insect sound", and it seemed that it was a customized staff uniform from the laboratory. Although it is a staff uniform, the texture is actually good, Xin Pet stared at the bee, only felt that the more he looked at it, the more fashionable it became, and he selfishly thought about when he would buy a similar one, so that he could be regarded as wearing a couple outfit with him.

Yes, being allowed to spend the night at his house exceeded her expectations, and she thought it would be nice to be able to spend a night with him in the office, but she didn't expect to be able to sleep directly at home.

Ye Shichao lost the concept of home because of what happened when he was a child, and his house was his hotel, and he never invited others to be guests, because it was meaningless, no one would invite others to the hotel as guests. And this time he invited her to go, which was a precursor to the gradual recovery of the concept of home, and if she could go in and out of his house often at this time, he would be taken for granted in the scope of home.

Of course, the premise of all this is that he has enough trust in her. This kind of trust is very rare, at least in a person like him, who has been traumatized, in order to protect himself, to stress an indifferent personality, and to minimize his emotions and relationships.

Trust is the key to open the prison of his soul, the shackles, and the next step is love.

Xin Pet followed him home, lived in his guest room, and even put on his pajamas, used his newly bought toothbrush, and even used his skin care products after taking a bath.

This sense of intimacy made her happy, she walked around in her pajamas, one would go to the kitchen to pour water and drink, and the other would go to the balcony on the second floor to blow the wind, humming a song all the time, she was happy, and when she looked up, she saw Ye Shichao standing in the corridor looking at her.

His room had an en-suite bathroom, he had already taken a shower at this time, he was wearing the same pajamas as hers, his hair was still wet, and his eyes seemed to have not come out of the fog of the bathroom, with a little fog, which looked gentler than during the day, and because it had become unreal.

"Why don't you sleep yet?" Xin Pet held the cup, a little nervous, but that little nervousness was nothing in front of the joy when he saw the same pajamas on the two of them, "Did I disturb you?"

Ye Shichao shook his head, there was still mist in his dark eyes, but his expression was very serious, "There is one thing, I want to make it clear to you." ”

His earnestness made her heart "chuckle", and her mental activity instantly changed from pleasant just now to self-examination:

Am I going too far today, asking him to demonstrate the experiment, asking him to accompany him to the Dance of Light, and finally staying at his house and putting on his pajamas...... Ahhh......h If you make one wrong step, your previous efforts will be in vain!

Just as her self-criticism was in full swing, thinking about how to apologize to erase tonight's excesses, he slowly reached out and took her hand.

She was stunned for a moment, and then heard Ye Shichaoyang say: "Through this period of contact, I am very sure that my feelings for you have become strong enough to want to have you, so ...... Can we get into a formal relationship?"

Just now, the soul was still at the bottom, and it was thrown into the sky all of a sudden, Xin Pet was a little confused, and he stayed for a long time, and he didn't come back to his senses.

"Of course, if you feel less comfortable feeling for me during this time and want to cancel your previous transaction, you can do that, I fully respect your wishes. Seeing that she didn't speak, Ye Shichao added another sentence, and there was a slight fragility in his eyes.

Xin Pet didn't have time to stop the words, his body moved one step ahead of her, threw himself into his arms, and hugged his waist tightly, "Agreed, agreed...... A hundred yes! I'm your girlfriend now. ”

The three words "girlfriend" made Ye Shi raise the corners of his lips, and he hugged her tightly, lowered his head and kissed her fragrant hair, "Girlfriend! ”

Xin Pet couldn't describe the mood at this time, his heart seemed to be filled with pink heat, swelling, scorching, nowhere to put it, and inexplicably steady.

She blushed and looked up, "My boyfriend is also very nice." Especially when the complete sentence is 'My boyfriend is Ye Shichao'. Before the words were finished, the person was already smiling, his smile was full of honey, and it was extremely sweet, "Ye Shichao, I really like you so much." ”

Ye Shichao was infected by her sincerity and frankness, and said in a low voice, "Me too", and couldn't wait to kiss her on the lips.
