Zhen Nuan's hand trembled and hit Dong Sisi's inner thigh.
She immediately straightened up and took a few steps back. "After the examination, you can put on your clothes."
Dong Sisi sat up, in no hurry at all, and looked carefully at the expression on her face. "You don't seem to be angry?"
"Because you're lying." Zhen Nuan took off her gloves meticulously, and her tone was affirmative.
Dong Sisi put a bra on her body. "Yes, I can tell truth from lies."
Zhen Nuan turned her head to look at her, her eyes unfriendly. Had she come to find fault on purpose?
"Even if you are angry, you don't look fierce."
"Fierceness doesn't bring momentum."
Dong Sisi continued dressing. "Shen Yi kidnapped me... You should know that this is true."
Zhen Nuan remained silent and threw her gloves into the trash can.
"He didn't do anything—just trapped me for a day and a night, had a few women forcibly change my clothes, and let me go the next day." Speaking of this, even Dong Sisi gritted her teeth slightly. "Those women actually... on my neck and chest."
"..." Zhen Nuan didn't expect the hickeys to be from women. "I thought it was Shen Zetian."
"Would he still touch me now?"
Zhen Nuan was speechless.
Shen Yi hadn't done anything, yet he'd broken apart a married couple. She thought for a while and said, "You can explain to Shen Zetian that you're not injured, and he should believe you."
"He's the most suspicious, saying that Shen Yi has always been ruthless in his work, that he wouldn't show mercy to my subordinates at all, let alone..."
The words weren't spoken, but Zhen Nuan guessed it was the sentence from earlier: "In order not to cause harm to yourself, obey and don't resist."
She didn't know Shen Yi's style of conduct. She only knew he'd changed a lot for her.
"I never ask about Shen Yi. I'll give you a certificate, but the main thing is that you and Shen Zetian trust each other..."
"Hmph." Dong Sisi laughed softly. "I don't need a useless piece of waste paper. I'm just here to see you."
Zhen Nuan was puzzled.
"You say that Shen Zetian and I don't trust each other enough. What about you and Shen Yi?"
"If you're talking about his business or interpersonal matters, I'm not interested." She washed her hands with hand sanitizer.
"You don't care if he kills someone."
Zhen Nuan's hand paused for a second, then returned to normal.
"You don't believe me? Jiang Xiao's death—he has a share in it."
Zhen Nuan slapped the faucet. "You're the one who killed Jiang Xiao, but the law can't touch you. You knew that she wanted to fake suicide and frame you, so you went upstairs to cooperate and let her perform."
Dong Sisi didn't answer directly but said lightly, "I was with Zetian after Jiang Xiao broke up with him. But this woman was ridiculous enough to say she was willing to have no title. The original girlfriend now wants to be a mistress?
A woman who delusionally relies on marriage to become Cinderella and a princess is herself a delusional fool. She also said she'd paid with her youth and true love as a victim. Would she have paid if Zetian had no money? She dreamed for too long and deceived herself, thinking she truly loved Zetian, but what she really loved was only the luxury and material things behind him."
Zhen Nuan couldn't say she was wrong, but she didn't want to recall Jiang Xiao's tragedy anymore. She wordlessly pulled tissues to dry her hands.
"I indeed hated her because Zetian really liked her. She was inferior to me in every way, yet wanted to step on my face with this, thinking that with a man's love, she was superior to me, showing off in front of me. Hmph, she wanted to court death herself—why wouldn't I oblige?" Dong Sisi spoke unusually clearly and calmly. "Of course, if Shen Yi hadn't sent Jiang Xiao over, none of this would have happened."
"What do you mean?"
"Dai Qing had someone tell Jiang Xiao's sister-in-law about the wedding. He also had the waiter let Jiang Xiao into the venue without an invitation."
Zhen Nuan froze. Though she didn't want to believe it, her intuition told her Dong Sisi wasn't lying.
Dong Sisi saw her face pale slightly and said, "He kills people, you examine corpses. You two are truly suited for each other."
Zhen Nuan recovered her composure in a moment. "There's no need to voice such provocative words."
Dong Sisi wasn't the type of woman to bluster. She spoke only to the point. She finished dressing, said "Goodbye," and walked straight out the door.
"Dong Sisi!"
She stopped.
"You loosened the screws on the railing, didn't you?"
She didn't answer, only laughed lightly. "Do you want to lecture me?"
Zhen Nuan lowered her voice. "I just thought you were excellent enough to choose your lover freely."
Dong Sisi turned her head to stare at her. "How do you know I don't love Shen Zetian?"
"How much impurity is there?" Zhen Nuan asked softly.
"I don't understand why so many women knowingly become mistresses when men already have stable relationships. Why do their happiness, glory, and so-called face have to exist through dependence on men? And many times, these men's appearances or inner qualities aren't elegant at all.
Many women are economically independent, but spiritually cannot be. I don't understand Jiang Xiao, but I understand you even less. You're so excellent—family background, education, connections, experience—how many women in Yucheng can compare to you? But why are your emotions controlled by one person? Why does your spirit depend on a man to live?"
Dong Sisi's face remained calm. For a full dozen seconds she said nothing. Finally, she smiled indifferently. "Shen Zetian is an elegant, good man."
Zhen Nuan was quiet for half a second, then said no more. "If that's what you believe."
Dong Sisi bit her lip lightly. "What about you? After everything I just told you, is your Shen Yi elegant enough?"
Zhen Nuan was slightly stunned. Dong Sisi smiled faintly and turned to leave.
Zhen Nuan rubbed her hands with tissue until they turned red, not understanding what Dong Sisi had come to upset her about today.
Shen Yi, Shen Yi—why could she never get close to him, yet always had an inexplicable sense of trust in him?
At this moment someone knocked on the door. Da Wei poked his head out. "Teacher, the mannequins and weapon molds are all ready."
Zhen Nuan made an acknowledging sound, threw away the tissue in her hand, closed the door, and went with Da Wei and the others to the crime simulation lab. She'd been looking forward to using the simulation lab, but today she couldn't muster any excitement.
In the center of the simulation room was a protective glass house with a life-sized mannequin fixed inside.
Zhen Nuan went over to touch it. The bionic scalp and bone texture could rival a real human head.
In front of the mannequin were four or five crime tools that the assistants had found according to Zhen Nuan's requirements—a gourd-shaped wooden chair armrest, a triangular chair leg, coral-shaped steel decorations...
Zhen Nuan put on goggles and gloves directly. Xiao Song and Da Wei were also preparing to put theirs on when they saw her and looked at each other, saying in unison with surprise, "Teacher, you're doing it?"
"What, you look down on women for not having strength?"
"Of course not, haha." Both young men laughed sheepishly. "We just meant that we men should do the physical work."
"No need. Consider it exercise." Zhen Nuan smiled and tilted her head, signaling for them both to exit the glass house.
She gripped the iron rod, aimed at the top of the dummy's scalp, and viciously smashed down. The fierce impact sound, mixed with the crisp sound of the dummy's head bones breaking, echoed in the glass house.
She glanced at the wound, nodded, and recorded it. Very quickly, she picked up the next simulated weapon and, without pausing, raised it and struck down hard—another muffled sound similar to striking a skull.
Outside the glass, Xiao Song and Da Wei exchanged glances: their beautiful teacher usually looked soft and gentle, but actually wasn't weak at all.
Zhen Nuan struck several times with such force that the recoil left both her hands numb. The process of hitting the dummy was almost a kind of venting—the harder she struck, the harder it became to stop.
Zhen Nuan gritted her teeth and used various tools to smash several dummy heads to smithereens without pause.
She didn't stop until she had no strength left, until her whole body was hot and covered in sweat.
Zhen Nuan breathed rapidly, looking at the fragments flying everywhere and the messy heads. She was a bit dazed herself, not knowing why she'd been so violent, as if a great fire had been smoldering in her heart.
Her hands were both numb and painful. Thinking of Xiao Song and the others watching from the side, she felt somewhat embarrassed. She calmed herself down and turned to look back, her heart suddenly jolting.
Xiao Song and Da Wei were both gone, replaced by an even taller figure.
Yan Yan stood outside the glass house, his dark eyes bright as he watched her, his expression quite interesting.
Obviously, he'd seen her entire violent process.
Zhen Nuan was slightly embarrassed. She smoothed the hair at her temples, removed her goggles, and walked out.
She raised her head and said with mock seriousness, "Ahem, I've been doing an experiment recently—collecting and studying the relationship between brain injuries and murder weapons."
Yan Yan nodded, the corners of his lips holding a smile of deep meaning, and asked, "Does this laboratory meet your satisfaction?"
Your satisfaction...
Zhen Nuan was greatly embarrassed but forced her expression to remain calm, coughing. "Mm, it's quite good. Very good."
Could she not hear his underlying meaning? That she was using the laboratory as an emotional outlet?
"Not bad." Yan Yan said half-mockingly. "If you work so hard, you'll definitely get a bonus."
Working hard, desperately... Of all the words, he chose "working hard"...
Zhen Nuan's face turned red, and her ears burned.
Yan Yan looked at her with a smile for a long time, then raised his index finger and drew a line across his forehead.
Zhen Nuan was stunned for a moment, then hurriedly looked away with a sigh in her heart. She took out a tissue from the pocket of her white coat and quickly wiped the sweat from her forehead.
When she turned back to ask what was going on, Yan Yan had already flashed out of the simulation room.
So he'd just stopped by to take a look?
She exhaled softly.
Zhen Nuan returned to the office and stayed there for a while.
When the hour hand pointed to five o'clock in the afternoon, she came to her senses. Now that Jiang Xiao's case was closed, she wanted to organize the information and archive it.
When she looked through the DNA comparison of bloodstains on the flower thorns, she found that although Dong Sisi's DNA didn't match the bloodstains on the flower thorns, the similarity was very high. This wasn't common, but it wasn't rare either. It often happened between siblings, and sometimes between strangers as well.
Zhen Nuan didn't care much at first, but an indescribable feeling kept grinding in her heart.
There was still some time before work ended, so she took the information to the blood analysis room. There was only one assistant in the analysis room. He pulled out all the data from PCR electrophoresis and various experiments to show Zhen Nuan.
Zhen Nuan was halfway through when she frowned. "You only used DNA in the cytoplasm for DNA comparison?"
The assistant looked embarrassed and rubbed his head shamefully. "I did do it, but I got distracted in the middle and forgot to check the nucleus. Because of this, I was also trained by the captain."
Seeing his ashamed appearance, Zhen Nuan relented and comforted him. "It's just that the procedure requires using both, but cytoplasm comparison is the same. I only remembered when I saw only one result. If I'd operated it myself, I might have only used one too."
"That's right, but this time is different." The assistant's face turned even redder. "I made a mistake, but fortunately, I didn't make a big mistake."
"Huh?" Zhen Nuan was puzzled.
At this moment, Guan Xiaoyu came in from outside.
After understanding Zhen Nuan's intentions, Guan Xiaoyu explained, "The bloodstains on the flower thorns are indeed Jiang Xiao's, but there's a problem with Dong Sisi's DNA comparison. This time we encountered an extreme case that happens once in a century—the DNA in the cytoplasm doesn't match 100%, but the DNA in the nucleus matches completely."
Zhen Nuan: "You mean Dong Sisi's nuclear DNA matches Jiang Xiao's bloodstains on the flower thorns? Previously, because only cytoplasmic DNA was checked, although the similarity was high, it wasn't fully matched, so it was overlooked?"
"Yes."
"How is this possible..." Zhen Nuan was stunned. "Are they identical twins?"
"Yes. Investigators found that the Dong family gave birth to twins, but when they were still in the nursery, one of the babies was burned by boiling water and died of tetanus. Now the Dong family can't believe that Jiang Xiao is the other child." Guan Xiaoyu shook her head. "Everyone thinks it's incredible."
"But they don't look alike at all."
"Maybe it's a change in appearance. You see, except for a string of gene sequences in the nucleus, the two of them aren't even apart in height and shape. Jiang Xiao's growth environment was too harsh—she's thinner and shorter than Dong Sisi. She's so pitiful. No one knows how she got to where she is today."
Zhen Nuan felt a little sad. After a while, she asked, "After Dong Sisi found out, did she react?"
"How can she have feelings for a twin sister she's never met or gotten along with?"
"True." Zhen Nuan muttered to herself, then said, "The captain is so amazing—this kind of thing can be discovered by him. No wonder Assistant Li said he was lucky. If he'd only checked the nucleus and not the cytoplasm, I'm afraid he would have wrongly accused Dong Sisi. Moreover, twins also have a small portion of the same cytoplasmic DNA."
"Of course he's amazing. I feel more and more like he's a god now." Guan Xiaoyu said, "He added the clause about double examination of nucleus and cytoplasm in the C-Lab experimental specifications."
Zhen Nuan raised her eyebrows in surprise. Captain Yan even understood this. He deliberately added this article—had he encountered a case involving twins before?
She thought about it for a while but couldn't understand it.
Well, following this captain in the future would bring a lot of pressure. However, she would definitely learn more and progress faster!
