Xiao Yifei looked at Zhao Ziguo and scratched his head, his eyes filled with confusion. It took him a while to recall who the person in front of him was. Finally, Xiao Yifei spoke, "You're Doctor Zhao Ziguo, right? How did you get here? When did I become your 'big brother'? You're quite a bit older than me, aren't you?"
"Uh." Zhao Ziguo's face suddenly turned red, and the situation instantly became awkward. He turned his head towards Xiao Yifei and said, "I once said that as long as you cured Jiang Mingquan's illness, I would follow your orders to the letter, but you didn't hear that. A man must keep his word. I said I would follow your orders, but calling you 'my life' would be too mushy! So I had to start calling you 'big brother' instead!"
Xiao Yifei clearly heard Qian Wu, who was standing behind Zhao Ziguo, trying hard to suppress his laughter.
"So that's what it was!"
