According to Qing, the mole.
These Spiritual Roots have clearly been erupting in secret for some time now.
They've taken over certain cities and infected a large number of residents, and those Pseudo-humans have already begun to breed.
So, they've bred a batch of "seeds" and spread them across various parts of the ocean via currents.
Just like dandelions.
A batch arrived at Fish Wine City yesterday; I suspect there'll be another today.
Provided the ocean currents haven't changed!
Moreover, they can trace the direction of the currents to find the source and see which source city has been heavily polluted by the Pseudo-humans.
Of course, blacksmiths aren't interested in that.
No matter what, tonight, a bunch of people started waiting for treasures to fall from the sky.
They even made an electronic Wooden Fish before sleeping, tapping away all night.
The strangest thing for Ning Zheng was that now every small blacksmith at the manor had an electronic mechanical Wooden Fish.
