At the military's group wedding, my best friend and I swapped husbands.

Chapter 125 We're in the lab, what are you kissing for!

Lin Weiwei followed Bai Si'an to the table by the window.

Several blueprints were spread out on the table, with drawings of circuits and parts that she couldn't understand. Next to them were several dark metal boxes, some of which had been opened to reveal a dense network of loose wires inside.

"This is it." Bai Si'an picked up one of the boxes and pointed to a modified area on the outer shell. "The original seal wasn't good, and sand would easily get in when it was windy and dusty, affecting the signal. I added a rubber ring here, and the gaps have also been repaired."

He spoke concisely, but Lin Weiwei only half understood what he was saying, so she had to lean closer to see.

Bai Si'an had a faint smell of engine oil mixed with his own clean scent, which wasn't unpleasant.

His fingers were long and slender, with thin calluses on the pads, and he touched the metal casing with a steady motion.

"If you're going to draw it," he continued, "just draw a comparison diagram. The left side is the original, where the sand goes in from here, and the right side is the improved version, where a rubber ring has been added so the sand can't get in. Just write a few words of explanation next to it."

Lin Wei nodded slightly, took out a pencil and notebook from her cloth bag, and began to draw a sketch based on the actual object.

She first sketched the shape of the box, then carefully drew the location where the rubber ring would be installed.

Sometimes when I don't understand a drawing, I look up and ask, "Is this how it is?"

Bai Si'an leaned over to look, and the two heads were almost touching.

His breath brushed gently against her ear, and Lin Weiwei felt a tickle in her ear, so she quietly moved to the side.

Bai Si'an noticed it, pushed up his glasses, didn't say anything, but just stood up straighter.

The other technicians in the room were all busy with their own work, and no one paid attention to this side.

The only sounds were the hum of the machines and the occasional soft clinking of tools.

After Lin Weiwei finished drawing the sketch, she added a few lines of small notes next to it, based on Bai Si'an's explanation.

She lowered her head slightly as she wrote, her eyelashes drooping down and casting a faint shadow under her eyes.

The pencil was held in her hand, her fingertips slightly white from the force she was applying.

Bai Si'an stood aside and watched.

Look at her focused expression, see her pursing her lips from time to time, and see the slight curve of her lips that unconsciously appears when she reaches a point she's satisfied with.

He suddenly felt a little itchy inside.

It felt like being gently tickled by a feather.

He glanced inside the room.

Li was talking to someone in the inner room, while the other two technicians were engrossed in debugging the equipment, and no one was looking this way.

The window was open, and outside was a small path; at this time of day, there weren't many people passing by.

Bai Si'an pushed up his glasses and glanced at Lin Weiwei again.

She was drawing a crucial part, her brows slightly furrowed, completely unaware of his gaze.

He suddenly reached out and grabbed her wrist, which was holding the pen.

Lin Weiwei was startled, and the tip of her pen drew a crooked line on the paper.

"What are you doing..." She looked up, but before she could finish speaking, Bai Si'an pulled her to her feet.

He put his other arm around her waist, gently pulled her against the metal cabinet behind him.

The cabinet was cold, and when Lin Weiwei pressed her back against it, she instinctively shrank back.

Bai Si'an had already leaned down and kissed him.

Lin Weiwei was stunned. The pencil and notebook in her hand fell to the ground with a soft sound.

She opened her eyes wide and looked at Bai Si'an, who was so close to her.

His eyes were closed, and his long eyelashes behind his glasses trembled slightly.

His lips were a little dry and hot, pressed tightly against hers, making it impossible for her to refuse for a moment.

Lin Weiwei realized what was happening and pushed him away by placing her hand on his chest.

Bai Si'an didn't move; instead, he kissed her even deeper.

Lin Weiwei's mind was buzzing, her legs felt weak, and she unconsciously grabbed his shirt in front of her chest.

After a while, Bai Si'an stepped back a little, his breathing becoming somewhat heavy.

Lin Weiwei, panting and her face burning hot, whispered, "Bai Si'an, are you crazy? We're at work right now!"

"Mmm," Bai Si'an responded, then leaned in and pecked her lips. "Just one kiss."

"You're even calling out?" Lin Weiwei glared at him, her eyes glancing at the open door. "There are people outside, and the door's not even closed... You're really... unreliable!"

Bai Si'an looked at her flushed face and smiled slightly: "It's okay, they're busy, they can't see."

As he spoke, he lowered his head and kissed her again.

Lin Weiwei initially tried to struggle, but after being kissed into a daze, she slowly loosened her grip on his clothes and instead wrapped her arms around his neck.

The two kissed in the quiet laboratory.

A breeze blew in from outside the window, stirring up grains of sand that rustled against the glass.

Li's voice could be heard coming from inside the room, rising and falling in pitch.

But at this moment, Lin Weiwei couldn't hear anything.

All they could hear was their intertwined breaths and their increasingly rapid heartbeats.

Her heart was pounding as she worried that they would be discovered, yet she also enjoyed the feeling of being intimate in secret.

Meanwhile, at the training ground in the Gobi Desert.

Bai Rongbei stood at the front of the column, watching the soldiers cross the river carrying heavy loads.

The sun was scorching, and the ground was steaming hot.

The soldiers, carrying dozens of kilograms of equipment, ran on the gravel road, sweating profusely, their steps heavy yet orderly.

Bai Rongbei stood with his hands behind his back, his gaze sweeping over the ranks, but his mind involuntarily drifted back to last night.

Su Wanwan slept in his arms, a tiny, curled-up ball, her face pressed against his chest.

She's restless when she sleeps; her hands will unconsciously grab his clothes, and her legs will drape over him like a kitten that has found its nest.

He was not used to it at first and dared not move.

Later, as I relaxed, I held her in my arms and inhaled the faint fragrance of her hair, and surprisingly, I slept soundly.

When he woke up in the morning, she was still nestled in his arms, fast asleep.

Her long eyelashes drooped down, her lips were slightly parted, and her breathing was light and gentle.

He watched for a while before gently getting up.

Thinking of this, Bai Rongbei's lips unconsciously curled up into a smile.

Although it was quickly suppressed, it was still spotted by the sharp-eyed Zhao Dayong.

Zhao Dayong, the company commander of the third company, had been with Bai Rongbei for many years. He was bold and took advantage of a break to come over and asked with a grin, "Regimental Commander, what's so happy about that? You're laughing so happily."

Bai Rongbei glanced at him: "Who laughed?"

"Just now!" Zhao Dayong continued fearlessly, "His mouth was practically stretched from ear to ear! It's because your wife... took good care of you, isn't it?"

Several company commanders nearby also heard it and looked over, trying not to laugh.

Chen Jianjun coughed and replied, "Definitely. I've never seen the regimental commander daydream or laugh during training before."

Liu Jianxun chimed in, "Exactly. Looks like your wife is something else, she's got our regimental commander all under her thumb."

The smile on Bai Rongbei's face vanished instantly.

He glanced at the group of people, his eyes turning cold.
