She couldn't be discovered.
After lunch, Qian'er took another of the 9,999 Spring Harbingers.
The last few days had indeed been quite busy for two pregnant women, and they took a nap after lunch. When Gu Bailu woke up, she realized that Ah Luo might come looking for them, so she went into the grove behind the courtyard and found a wild goose. "Brother goose, do me a favor."
Two geese flapped their wings and came over. "What is your command?"
Any human who could speak the language of birds was an immortal, and they didn't dare be disrespectful.
"Help me deliver this letter to a man at 4 Auspicious Spring Alley. He's very tall and brawny."
One of the geese picked up the envelope. "Okay."
The pair of wild geese flapped their wings and flew away.
Walking around the grove, Gu Bailu caught a couple of black ants. "Go to the main courtyard and help me find out where that person called Su Muwei is staying."
