Wenren Sheng had naturally witnessed this through observing Huang Taiji's actions.
He had not gone north to take personal command.
Once he acquired ships of over 2,000 tons, he would not sail across the open ocean himself.
Coastal sailing within the strait was one thing.
After all, given the results of training this body, in the warm southern seas, he could cling to a piece of wood and drift-swim for a hundred kilometers.
In northern waters, though, that would only be possible if the Seed of Mystery took effect.
He immediately sent the news over again by fast ship.
A round trip by fast ship took around seven to ten days, assuming everything went smoothly.
He remembered that there was a type of super-fast ship that could reach sixty knots with favorable wind and currents—one hundred kilometers per hour.
It could arrive in less than two days.
There was an urgent need for a rapid means of transmitting messages.
Carrier pigeons could do it.
The prerequisite was holding the harbor and beginning to breed them now.
Every month, they would regularly transport carrier pigeons that had already become accustomed to their local areas.
Carrier pigeons relied on their homing instinct.

Pigeons reproduced quite quickly,
