Kiana, do you understand what filial piety is?

Yu Zhe stopped organizing his tools and looked directly at her from behind his glasses. "No," he said, his tone unwavering. "That kind of thing will affect the experimental data." He added, "Don't worry, I have no interest in your body. This is just a necessary inspection procedure."

"This..." Chen Tianwu showed a conflicted expression. She looked down at the last two pieces of clothing on her body. The light pink lace underwear looked particularly dazzling under the light.

Although she knew rationally that this was just for an experiment, her body's instinctive reaction made her so ashamed that she wanted to find a hole to crawl into.

So should she take it off now?

If she was still a male before, Chen Tianwu would not have had any hesitation, but now her body is that of a female!

But after hesitating for a moment, Chen Tianwu gritted his teeth and took off his underwear.

Her fingers trembled as she unfastened the clasp on the back, and the underwear slowly slid down her smooth skin.

Don't underestimate her awareness!

She would do anything for her sister!

Although Yu Zhe said before that kissing was impossible, now it’s just a matter of taking off clothes, why is she afraid?!

Isn't it just her body being seen? She had already been seen naked when she was a man!

So now there is nothing to be afraid of!

Chen Tianwu took a deep breath, her fair fingers trembling as she reached for the bra clasp on her back. Her skin shone like pearls under the light, and the lines of her collarbone were as graceful as a carefully crafted work of art.

With a slight "click" sound, the clasp of the underwear opened.

"Woo..." She couldn't help but let out a small whimper, and her cheeks instantly turned red.

The underwear slowly slipped off the shoulders, revealing skin as delicate as cream.

Her figure was slender yet curvaceous, her waist slender enough to hold one hand, outlining a captivating curve under the light. Two cherry-red spots loomed on the snow-white peak, rising and falling slightly with her rapid breathing.

"Is that okay..." Her voice was so soft that it was almost inaudible. She instinctively crossed her hands over her chest, while the other hand tightly blocked her lower body.

Her legs were pressed tightly together, her toes curled up nervously, leaving shallow marks on the floor.

Yu Zhe pointed to the examination bed next to him and said, "Lie down on it."

Chen Tianwu jumped onto the bed like a frightened rabbit and quickly pulled the white cloth next to him to cover himself.

Her fingertips were cold, but her whole body felt hot, especially when Yu Zhe approached with the testing equipment, she almost curled up into a ball.

"Don't... don't look at me like that..." She turned her face away, her voice trembling. The tips of her ears were red, almost dripping blood, and her neck was also flushed pink.

Yu Zhe paused and sighed, "Please remove the cloth, or I won't be able to operate."

Chen Tianwu's knuckles turned white as she clutched the white cloth. She took a deep breath, yanked the fabric away, and immediately closed her eyes tightly. Her long eyelashes fluttered like the wings of a frightened butterfly.

"Now that you've taken off your clothes, just cooperate." Yu Zhe's voice suddenly sounded so close that Chen Tianwu almost jumped up. "Lie down and don't move."

Chen Tianwu froze as she felt the cold metal probe touch her skin. She squeezed her eyes shut and silently chanted her sister's name, as if that would distract her.

But the more she tried to ignore it, the clearer the sensations in her body became—every touch made her shudder like an electric current.

"Relax." Yu Zhe frowned as he looked at the wildly fluctuating monitoring data. "I can't continue like this."

"I...I'll try my best..." Chen Tianwu's voice was tearful. She tried to take a deep breath, but because she was too nervous, she choked on her own saliva and started coughing violently.

Yu Zhe had to stop what he was doing and wait for her to calm down. A complex emotion flashed across his eyes behind the lenses, but he quickly regained his composure.

Completely different from Siegfried, I should say he's worthy of being a child...

"Listen," he said, his tone unusually soft. "Just think of it as a checkup at the hospital. Doctors don't discriminate by gender."

Chen Tianwu slowly stopped coughing and opened her tear-filled eyes. She looked at Yu Zhe's serious expression and suddenly realized that he really was just treating this as a job. This realization relaxed her tense nerves a little.

"I'm sorry," she whispered, trying to lie back down, her hands still clutching the sheets nervously. "You...you go ahead."

"Yeah." Yu Zhe nodded and picked up the feather. "Relax, this is just a routine check." He paused and added, "You can stop at any time if you feel uncomfortable."

Chen Tianwu bit his lower lip and nodded, forcing himself to loosen his grip on the bed sheet.

"Now, let's start testing the touch of the hands and arms." Yu Zhe said as he adjusted his position to ensure that he could clearly observe Chen Tianwu's reaction.

Chen Tianwu held his breath and watched the feather slowly approach.

"Don't be nervous," Yu Zhe noticed her reaction and stopped. "It's just like being brushed by a breeze. It won't hurt."

After saying that, Yu Zhe gently swept the feather across Chen Tianwu's hand, starting from the fingertips, with gentle movements as if he was treating something fragile.

"I, I know..." Chen Tianwu stammered, trying hard not to shy away, "It's just... a little itchy..."

Yu Zhe's mouth curved slightly, "Itching is a normal reaction."

Chen Tianwu's cheeks flushed slightly, she bit her lower lip, not knowing where to look. Yu Zhe noticed that her long eyelashes were trembling slightly, like the wings of a frightened butterfly.

He deliberately slowed down his movements, allowing the feather to stay in her palm for a few more seconds.

"You, don't do this..." Chen Tianwu's voice was as thin as a mosquito's, and his fingers curled up unconsciously.

Although he was just touching his hands, Chen Tianwu felt something strange about his body.

I wasn't wearing any clothes, but I felt inexplicably hot.

"Don't move." Yu Zhe ordered softly, "It will be fine soon."

The feather slowly moved upwards, lightly brushing against her slender wrist. Chen Tianwu took a breath and hunched her shoulders unconsciously.

"Yu, Yuzhe..." she protested softly, her voice trembling slightly.

"Just bear with it." Yu Zhe's voice was smiling, but his face was deliberately stern. "Scientific research requires a rigorous attitude."

When the feather reached the inside of her forearm, Chen Tianwu couldn't help but burst out laughing. "That's so itchy!"

Chen Tianwu tried to pull his arm back, but Yu Zhe held it firmly.

"Hold on a little longer." Yu Zhe's voice suddenly grew serious, his eyes fixed intently on her slightly flushed skin. His slender fingers gently pinched the white feather, his movements deliberately slowed down. "The data here is very important."

The feather continued to move upwards, gently brushing over the hollow of her elbow. Chen Tianwu's breathing became noticeably faster.

She could clearly feel the gentle touch of the feathers, like an electric current running from her shoulders all the way up her spine. "Are you...are you sure this is collecting data?" she muttered softly, a faint blush spreading across her cheeks.

When the feather reached his shoulder, Yu Zhe's movements became even gentler. "Of course, I won't lie."

The feathers continued upwards, reaching the sides of her slender neck.

Chen Tianwu could feel her pulse beating faster. She bit her lower lip, trying hard not to make any sound.

Yu Zhe's gaze lingered on the tip of her red ear for a moment, and a hint of amusement flashed in his eyes.

"Here..." The feather gently brushed across her neck, and Chen Tianwu took a deep breath, "It's... too itchy!" Her voice trembled slightly.

"Just bear with it, it will be over soon." He deliberately slowed down his movements, the feathers barely touching her sensitive skin. "Your reaction is quite strong."

"You...you did it on purpose, right?" Chen Tianwu glared at him in embarrassment, but quickly looked away when she met his focused gaze.

Her heart was beating incredibly fast and even her breathing became disordered.

The feather finally reached her delicate collarbone, and Yu Zhe's movements suddenly became unusually gentle. He used the tip of the feather to meticulously trace the curve of her collarbone, as if drawing a precise blueprint.

"Here..." he murmured, a hint of admiration in his voice, "The curve is perfect."

Chen Tianwu's whole body stiffened, and he felt all the blood in his body rushing to his cheeks.

She bit her lips tightly, but still couldn't control the scream that blurted out: "Aiya~"

The voice was soft and sticky, with a hint of coquettishness that she herself was not aware of.

Yu Zhe paused for a moment, a hint of surprise flashed in his eyes, and then turned into a deeper smile.

He deliberately used the feather to gently touch the most sensitive part of her collarbone. "The reaction is even more interesting than I expected."

Chen Tianwu finally realized what sound she had made and was instantly mortified. She covered her red face with her hands, her voice muffled through her fingers: "Enough...enough?"

"No~" Yu Zhe replied softly: "Because the next one is the chest~"

150 Chen Tianwu: It’s going to get weird!

"Chest...chest?!" Upon hearing these two words, Chen Tianwu widened his eyes in horror, and his cheeks, which were already flushed, instantly turned red.

She instinctively crossed her arms over her chest.

"This...this can't be!" Her voice trembled violently, and even her eyelashes trembled slightly. Her blue eyes were filled with shame and resistance, and the corners of her eyes were wet, as if tears would overflow at any moment.

Just touching her collarbone with a feather made her look like this. Chen Tianwu couldn't imagine what she would look like if a feather was touched on her chest.

Those shameful images emerged uncontrollably in her mind.

It's definitely going to get weird!

Yu Zhe tilted his head, a confused expression on his face. "Why are you so resistant? This is just a normal physical examination."

He shook the feather in his hand. The white feather shone softly under the light, but it made Chen Tianwu shudder.

A normal checkup?!

No one would believe you!

Yu Zhe sighed and pushed his glasses up on his nose. Behind the lenses, he looked helpless. "You should have thought of this before. You know, this is one of the most obvious differences between men and women."

"But...but..." Chen Tianwu bit his lower lip, his eyes flickering, and even his voice trembling.

Even if she had guessed that this step might happen, it didn't mean she could accept it!

At this moment, she felt like a new soldier forced to come to the battlefield.

Before he arrived, the commander said some inspiring words to him, saying that as long as he returned alive, he would be a hero who saved the country and would be respected by everyone. His country's weapons were so advanced that defeating the enemy would be as easy as chopping melons and vegetables, and there would be no difference between being on the battlefield and being at home.

War is nothing more than a change of place of living.

But when she actually stood on the battlefield, saw the broken limbs everywhere, and heard the deafening sound of artillery fire, she realized that everything was a lie.

All that was left in her heart was fear...

"What do you mean by 'but'?" Yu Zhe suddenly raised his voice, frightening Chen Tianwu so much that he trembled all over. His tone was as harsh as a teacher scolding a student.

This made Chen Tianwu's body tense up. At this moment, she felt like she was back to her childhood when she did something wrong and was scolded by her father.

"I know you're very shy right now." Seeing Chen Tianwu hunching his shoulders, Yu Zhe softened his voice slightly, "But Chen Tianwu, think about it... Everything you're doing now isn't just for yourself, but for more people, including your sister..."

"Sister..." Chen Tianwu murmured repeatedly, his voice so soft that it was almost inaudible.

Seeing this, Yu Zhe leaned closer to her and said in a low, firm voice, "Indeed, the sacrifice you are making now is for the benefit of those affected by the Honkai, and it also forms the foundation for healing your sister in the future."

His gaze burned with undeniable power. "Think carefully! As long as we collect enough data from you and eliminate the side effects of this experiment, your sister won't suffer this pain in the future."

Chen Tianwu's shoulders trembled slightly, and his lips were pressed into a pale line.

Seeing this, Yu Zhe's eyes suddenly became sharp: "Or do you want your sister to go through this kind of pain?"

The look in Yu Zhe's eyes when he looked at Chen Tianwu at this moment was as if he was questioning her, why are you so selfish?!

Facing Yu Zhe's gaze, Chen Tianwu lowered his head in shame.

"I..." Chen Tianwu's voice choked, her eyes slightly red. The image of her sister groaning in pain appeared in her mind. The image of the thin figure curled up on the hospital bed made her heart ache.

Yeah, how could she be so selfish?! So cowardly?!

"I've clearly made up my mind just now, why are you regretting it again?!" Chen Tianwu's chest heaved violently, and his breathing became rapid and irregular.

Is she such a weak person?

No! Absolutely not!

Finally, she took a deep breath and raised her head. Although her eyes were still red, her gaze had become firm.

"Please continue!" Her voice was soft, but with a determination that could not be ignored. "I can still endure it!"

Yu Zhe's expression finally softened. He sighed softly and reached out to gently stroke the top of Chen Tianwu's head, his movements as gentle as if he were soothing a frightened animal.

"You don't need patience right now." Yu Zhe's voice returned to a gentle tone. "What you need to do now is to express your true feelings. If you feel comfortable, then you feel comfortable. If you feel uncomfortable, then you feel uncomfortable."

The warmth of Yu Zhe's palm relaxed Chen Tianwu's tense nerves a little. She asked in a low voice, "Then...what should we do?"

Yu Zhe withdrew his hand and looked her straight in the eye: "It's very simple, I ask you a question. Chen Tianwu, are you feeling comfortable or uncomfortable now?"

Chen Tianwu bit her lower lip, hesitated for a moment, and finally replied softly: "Comfortable...comfortable."

After saying that, she immediately turned her face away.

"Very good, that's right." Yu Zhe smiled with satisfaction. "Remember, honestly expressing your feelings is also an important part of the experiment."

After saying that, Yu Zhe gently pinched the white feather with his fingers and slowly moved it closer to her snow-white skin under Chen Tianwu's nervous gaze.

"Don't be nervous," he whispered, a hint of temptation in his voice. "This is just a basic test."
