110: Pigeons occupy the magpie's nest_4

This matter...

Seems a bit strange.

Gu Changyun pinched the bridge of his nose.

"Could it be a gene mutation?" continued Gu Changyun.

"It's not out of the question," Fu Lanshen replied, "Perhaps, you can go back and ask her one question."

"What question?"

Fu Lanshen gently swirled the red liquid in the goblet he was holding, watching it ripple in circles. After a moment, he parted his thin lips and said, "Just ask her if she knows 'cuckoo takes over the magpie's nest,' which bird the 'cuckoo' refers to."

"A cuckoo?" Gu Changyun scratched his head, momentarily unable to grasp the meaning, "Seventh Master, what do you mean by that?"

Fu Lanshen's expression remained unchanged, "Just the literal meaning."

"Then why do you suspect she's not my biological sister?" pressed Gu Changyun, "If she's not, then who is?"

"With intent..." Fu Lanshen's tone slowed, "one can naturally find out."

Meanwhile.
