That was the box where Gu Youyou kept her Western medical supplies, all of them crafted by artisans in Lingnan and after she arrived in Beijing; they were unique in this world.
Since it was a knife wound, they would presumably be needed.
She quickly went inside to fetch her commonly used medicine box and hastened out.
The doorkeeper had already prepared a carriage for her, but Gu Youyou, with a stern face, said lightly, "Saving lives is a race against time. How long will it take by carriage? I'll ride a horse instead."
With those words, she seized the horse that the Jie Residence's house servant had ridden to bring the news, mounted it, and galloped away, leaving everyone staring in amazement.
"Your family's young Miss can ride a horse?"
"I... I had no idea?"
"Since she has ridden off, just send the carriage back."
"Wait, I'll need it," Lin Qianqing rushed out in a flurry, the young Miss from the Du Family with her.
