The power of emotions was the real source of strength for the Underground City and the soil from which special buildings sprouted.
Mu Ying wondered when Little Stone would produce its first special building!

[Volume: stone brick house (12/55, ordinary), test house (0/5, special), test monument (0/1, special)](Well-fed with emotions, buildings come naturally, special buildings have surfaced, go build them now!)
Special? It really was the special she was thinking of!
"Little Stone, you're amazing! At three years old, you've already grown special buildings, and two of them!" Mu Ying said excitedly, pinching Little Stone, "Mommy's efforts weren't in vain!"
