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

Chapter 91 Bai Si'an Researches Sanitary Napkins

Bai Rongbei returned to the regimental headquarters and went directly to the training ground.

This morning was a weighted cross-country training session, and all the officers and soldiers of the regiment were present.

The sun in the Gobi Desert is scorching hot when it rises, making the ground scorching hot.

The soldiers, carrying 20 kilograms of equipment, ran on the gravel road, their footsteps echoing in unison, raising clouds of dust.

Bai Rongbei stood at the front of the line and blew his whistle: "Attention, everyone! Ten-minute break!"

The soldiers breathed a sigh of relief, removed their equipment, and sought out shady spots to drink water and catch their breath.

Bai Rongbei walked to a dead tree, unscrewed the kettle, and took a few sips of water.

Sweat streamed down his chin, soaking the collar of his military uniform.

Feeling hot, he simply unbuttoned his collar and rolled up his sleeves to his elbows.

Several company commanders gathered around to report on the training progress.

Company Commander Zhao Dayong, with his sharp eyes, suddenly exclaimed "Huh?" and stared at the area below Bai Rongbei's neck: "Regimental Commander, why is it red here?"

Bai Rongbei paused in his movements.

Zhao Dayong leaned closer to look, his eyes widening: "Oh, there are teeth marks? What... bit me? My sister-in-law's cat?"

Several company commanders nearby also looked over curiously.

A little below Bai Rongbei's neck, near his collarbone, there was a small, noticeable red mark, and you could even see teeth marks on the edge.

Bai Rongbei remained expressionless, pulling his collar up slightly: "It was from mosquito bites."

"A mosquito?" Zhao Ming chuckled. "What kind of mosquito is so strong? It can even leave teeth marks?"

The other company commanders suppressed their laughter and exchanged knowing glances.

Second Company Commander Wang Qiang coughed and said, "Old Zhao, what do you know? The mosquitoes in the Gobi Desert aren't the same as elsewhere, are they? They're big and tough!"

"Exactly!" Liu Jianxun chimed in, "One bite, and it feels like being clamped by pliers!"

Several people were talking nonsense with a straight face, their eyes full of mockery.

Bai Rongbei glanced at them, ignored their response, and directly changed the subject: "Break time's over. Let's continue training!"

He blew his whistle, and the soldiers regrouped.

As Zhao Dayong ran back to the group, he whispered to Chen Jianjun, "That doesn't look like a mosquito bite..."

Chen Jianjun chuckled: "Who cares what bit him? Anyway, the regimental commander is in a good mood and didn't scold anyone."

Training continues.

Bai Rongbei ran at the front of the group, his back straight and his steps steady.

A breeze blew by, and the collar opened slightly, revealing the faint red mark.

He recalled how Su Wanwan had drunkenly nibbled at his abs last night, and the vague "big chicken leg" she had uttered.

The corners of his mouth curved almost imperceptibly.

It really is a "kitten".

It bites quite hard.

Bai Rongbei was in a good mood. He turned to the team and shouted, "Two extra hours of training today, and an additional 20 pounds of weight!"

Upon hearing this, the crowd below erupted in lamentation.

"Wasn't it said that Commander Bai was in a good mood?"

"You can add extra training if you're in a good mood..."

"Two extra hours of training, are they trying to kill us?"

"Forget it, let's not tease Commander Bai anymore! We can't afford to mess with him!"

……

In the family compound, Bai Si'an didn't even eat lunch and rushed home after work.

Su Wan went to work in the evening.

Lin Weiwei was the only one at home.

Bai Si'an was worried about leaving his wife alone at home, so as soon as he got off work, he went to the cafeteria to get food and ate with his wife.

Lin Weiwei's stomach was still a little bloated and painful, so she lay on the bed wrapped in a thin blanket.

Baisian carried the food into the house.

"Weiwei, how are you? Are you feeling better?"

Lin Wei frowned slightly as she replied, "Yeah, my stomach doesn't hurt as much anymore, but the flow was a bit heavy, and my pants are all dirty..."

Bai Si'an quickly helped the person up and placed the food on the table.

"You eat first. I managed to get some materials for the sanitary napkins you mentioned last night. I'll try to make some so it will be easier for you when you have your period."

While Lin Weiwei was eating, Bai Si'an moved a small stool and sat on the edge of the bed, holding a needle and thread and some scraps of cotton cloth and cotton.

He bought all these things from the service center, and the cotton was obtained from the health center; it had been disinfected.

He frowned slightly, staring intently at a piece of cut cotton cloth spread out on his knees, his expression as focused as if he were studying precise blueprints.

After finishing her meal, Lin Weiwei stayed with Bai Si'an as he made sanitary napkins. She looked at him listlessly and asked curiously, "Are you really going to do this? Will it even work?"

"Give it a try." Bai Si'an didn't even look up. He picked up the needle, threaded the needle, and said, "What you said last night, thick in the middle, with wings on both sides, and longer at the back to prevent leakage... It's theoretically feasible. The key is the fixation and absorbency."

His fingers were long and slender, and he held the needle and thread with surprisingly unremarkable skill.

First, sew a layer of cotton fabric into a long, narrow pocket shape, leaving an opening. Then, carefully stuff it with fluffy cotton, filling it evenly, and then sew the opening closed.

Finally, sew long strips of fabric onto both ends.

The first finished product looked rough, but the shape did look somewhat like the real thing.

"Here you go." Bai Si'an handed it over. "Want to try it?"

Lin Weiwei took it and felt it; the cotton padding was quite soft. She was a little embarrassed: "Now?"

"Hmm. I'll change it if it doesn't feel right," Bai Si'an said, turning around naturally.

Lin Weiwei blushed and quietly changed into her new clothes.

It's definitely more comfortable and fits better than stiff strips of cloth when you put it on.

"How is it?" Bai Si'an asked with his back to her.

"...It's alright," Lin Weiwei said softly. "It's just that the straps are a bit uncomfortable, and...is this fabric not very breathable? Won't it feel stuffy?"

Bai Si'an turned around, adjusted his glasses, and thought seriously: "The fabric can be changed to a softer, more breathable fine cotton. The straps can be made wider, or we can skip the straps altogether and find a way to glue them on..."

He paused for a moment, then said, "If we're going to stick it, we'll need the right glue. Let me think."

He picked up the cut cloth and cotton again and began his second attempt.

This time, he first sewed two layers of softer cotton fabric together, sandwiched cotton in the middle, to make a thicker long pad.

Then, two wider elastic bands were sewn onto both ends of the back.

"This," he explained, "is put over your underwear to secure it and test the tightness."

Lin Weiwei tried it out; the elastic band was quite elastic, held its position firmly, and wasn't too uncomfortable.

Seeing that Lin Weiwei wasn't tied up tightly, Bai Si'an pulled her into his arms and said softly.

"It's not fastened properly, let me fasten it for you again."
