At first glance, they seemed to be nothing more than finely crafted iron tools.

Chu Fengchun was about to look away when he noticed a small knife at the edge of the set.

The knife was exquisitely made and looked ideal for treating external wounds.

He picked it up for a closer look. As he ran his finger over the blade, Shen Qingwan quickly warned him,

“Be careful, senior. That knife is very sharp.”

Before she even finished speaking, a drop of blood had already appeared on Chu Fengchun’s fingertip. Instead of being alarmed, he was delighted.

“What a sharp knife!” he exclaimed.

Then, turning his attention to the other tools, he picked up a pair of tweezers.

A thought struck him—if a wound had foreign objects inside, wouldn’t these tweezers make it easy to remove them?

“This box contains tools for treating external injuries, along with a stethoscope,” Shen Qingwan explained.

As she spoke, she picked up the stethoscope and placed it on Chu Fengchun’s ears, then pressed the chest piece against his heart.

When the steady thumping of his heartbeat echoed in his ears, he was startled at first, then his eyes lit up with excitement.

“This… is my heartbeat?”

Amazed by this device, Chu Fengchun eagerly moved the chest piece toward Shen Qingwan’s heart.

Seeing his action, Murong Wushuang instinctively pulled Shen Qingwan back a step.

Though Shen Qingwan didn’t mind letting him listen, she was still a woman, and it wasn’t entirely appropriate.

So instead, she pressed the stethoscope against Murong Wushuang’s chest.

Because Shen Qingwan was already standing close to him, Murong Wushuang suddenly felt tense for no reason. His heartbeat quickened involuntarily.

The rapid thumping was evident through the stethoscope, causing Chu Fengchun to frown. “Murong, why is your heart beating so fast?”

The moment he asked, he realized it was a foolish question.

A racing heart usually meant arrhythmia or excessive nervousness.

As a physician, he understood that perfectly.

Before Chu Fengchun could say anything further, Murong Wushuang pushed the stethoscope away, looking somewhat flustered as if someone had uncovered his secret.

“Senior, perhaps you should check Madam Shen instead.”

Murong Wushuang assumed that since Shen Qingwan’s surname was Shen, her mother must be Madam Shen.

Shen Qingwan didn’t bother to correct him.

She had deliberately covered her mother’s face to prevent recognition.

After all, both Zhan Wang and Murong Wushuang were high-ranking nobles of the capital and might have seen her mother before.

She couldn’t afford to expose her identity yet.

Chu Fengchun cleared his throat and put the stethoscope away.

Shen Qingwan then introduced him to the rest of the surgical tools—over twenty pieces in total.

After learning their functions, Chu Fengchun was overjoyed, clutching the box as if it were a priceless treasure.

His attitude toward Shen Qingwan also improved significantly. “You don’t need to worry. Your mother’s illness is in my hands. Give me half a month, and I promise you’ll have a lively and healthy mother again.”

Chu Fengchun was the kind of person who was blunt when he disliked someone but warm and friendly when he changed his mind.

His demeanor had done a complete 180.

Murong Wushuang was also impressed after hearing about the tools.

If these delicate instruments truly worked for external injuries, they could make battlefield treatment far more efficient.

If military doctors had a set, wouldn’t it greatly improve their ability to treat wounded soldiers?

Still, Murong Wushuang knew these tools were rare and valuable.

Owning even one set was difficult enough—getting more seemed impossible.

Shen Qingwan was relieved that Chu Fengchun had agreed to treat her mother.

However, since the treatment would take half a month, it wouldn’t be convenient to stay in the military camp.

She doubted Zhan Wang would allow outsiders to remain in the camp for so long.

“Thank you, senior. But since the treatment requires half a month, would it be possible for you to stay with us in Yanzhou City for that time? If not, I can bring my mother to the camp each day.”

Yanzhou City was the closest settlement to the Northern Army Camp, but traveling back and forth by carriage would take most of the day.

Still, for her mother’s sake, she was willing to make the effort.

At the mention of leaving, Chu Fengchun’s expression darkened.

He snorted, “Even if I wanted to leave, I’d still need Zhan Wang’s permission. I can’t just go as I please. Your mother will need daily acupuncture and herbal baths to detoxify her body. The journey would be too much for her. You’d be better off asking that Murong kid to arrange a place for you to stay here.”

After all, Murong was the one who requested the treatment—it wouldn’t be fair for Chu Fengchun to accommodate everything.

Besides, they only needed two tents, which wasn’t too much trouble.

Murong Wushuang immediately agreed.

After all, Shen Qingwan had donated twenty thousand stone of grain.

“If Madam Shen’s condition makes traveling difficult, then Shen Gongzi, you should stay in the camp for now. However, military regulations are strict, and security is tight. It won’t be as comfortable as the city.”

Shen Qingwan had no problem with that. Since they were offering a place, she was more than willing to accept.

“In that case, I appreciate your hospitality.”

Since they were in someone else’s territory, she remained polite.

Murong Wushuang then went to arrange the tents.

He also needed to inform Beichen Yuan, as keeping outsiders in the camp required approval.

Military tents were in short supply, so he couldn’t place them too far away.

There were two small tents behind the command tent, but since they were close to the main area, he wasn’t sure if Beichen Yuan would approve.

“What took you so long? Did some past romantic debt catch up to you?”

Beichen Yuan and Murong Wushuang were as close as brothers, having grown up together.

They often teased each other when alone.

Murong Wushuang was used to it and simply gave him a knowing look.

“It’s that Shen Gongzi who helped gather the military grain.”

“The one you said was interesting?”

By now, the strategy tent was empty except for the two of them.

Beichen Yuan was idly adjusting the small flags on the war map as he spoke in an indifferent tone.

Murong Wushuang had mentioned Shen Qingwan multiple times after returning, which was why Beichen Yuan had taken notice.

When Murong Wushuang described him as “interesting,” it had piqued his curiosity.

If not for the fact that Shen Qingwan was a man, Beichen Yuan might have suspected Murong had taken a romantic interest.

Murong Wushuang didn’t deny it and explained their current situation. “Shen Qing came to donate grain in exchange for medical treatment for his mother. Senior Chu said it would take half a month to cure her. If you don’t plan to let him leave for now, then we’ll have to let them stay in the camp.”
