Qin Susu was so excited just thinking about the nine hundred taels of silver that Prefect Xie had given to Qiu Yan that she couldn't stop thinking about it.

From now on, they can eat whatever they want without restraint.

Qiu Yan automatically ignored the second half of Qin Susu's sentence: "I want to create a drug that can fight infection."

Is it okay to eat? I think it's fine.

"What?" Qin Susu didn't understand at all.

Ling Qi and Ling Ba also looked completely bewildered.

Qiu Yan put down the moldy steamed bun and patiently explained:

"As we all know, if soldiers are unfortunate enough to suffer severe knife wounds, most will die from infection. Furthermore, if Young Master Xie's wound is unfortunately infected, it will be very difficult to heal."

So I thought about developing a drug that could resist infection.

Resisting infection? The three seemed to understand what Qiu Yan said, but they also seemed not to quite understand.

Wasn't it the wound that became infected and ulcerated, leading to death?

"What do you mean by infection?" Ling Qi asked.

He also knew that ordinary wounds would heal on their own, but severe knife wounds had a high chance of being fatal.

"It means that the wound area is obviously red, swollen, and the skin temperature is elevated. The patient will also experience pain, and the wound surface is unhealthy, with necrosis occurring. In this case, the wound surface has been eroded by bacteria, causing infection."

After hearing this, Ling Ba nodded: "If our soldiers are injured, they will inevitably develop abscesses in their wounds. Once the abscesses develop, they will surely die."

Thinking of his brothers who had fought valiantly on the battlefield, he felt a surge of hope for Qiu Yan.

If Xiaoyan succeeds in this endeavor, the soldiers will surely be eternally grateful to her.

Qiu Yan: "Yes, an abscess outbreak is what I call a wound infection. Small wounds can gradually develop into large, festering wounds, which can lead to sepsis and death."

Qiu Yan glanced at the moldy steamed bun in front of her again.

Just thinking about it makes me realize how difficult it is.

Ling Qi and Ling Ba roughly understood what Qiu Yan meant, but what was the connection between this medicine and the moldy steamed bun in front of her?

They couldn't understand it.

Needless to say, Qin Susu couldn't understand it either.

Qiu Yan knew that even if she explained, the three of them might not understand, so she simply stopped explaining.

"Because of Young Master Xie's injuries, I need to stay for a few more days before I can leave." She had only explained the matter to Prefect Xie and had not yet sat down with Ling Qi and Ling Ba to discuss it in detail.

"Xiaoyan, this is not appropriate." Ling Qi shook his head, indicating his disapproval.

Qiu Yan, aware of Ling Qi and the other two's doubts, explained:

"Young Master Xie needs a recovery period. I will be monitoring his condition closely these next few days. It shouldn't take too long, at least seven days, at most half a month."

Qin Susu didn't care; wherever Qiu Yan was, she would be too.

Ling Qi and Ling Ba, on the other hand, were also concerned with matters of national importance.

Ling Ba shook his head: "If we are too late, I'm afraid Qin Feng's men will gain the upper hand."

He certainly understood Qiu Yan's meaning.

Qiu Yan: "Therefore, I want you to set off today." Upon hearing this, Qin Susu nodded in agreement.

"That's right, how come I didn't think of that? Ling Qi and Ling Ba, you go first, we'll be there shortly."

"inappropriate!"

"Can't!"

Ling Qi and Ling Ba both refused.

This is not Baiyang; this is the territory of Northern Qi.

"My two cousins, I've been traveling for so long and I'm really exhausted. Can't you let me rest for a bit?"

Qiu Yan's softened tone made Qin Susu's lips stretch almost to her ears in a wide grin.

"Yeah, I want to rest too."

"Xiaoyan, our duty is to protect you," Ling Ba said solemnly.
