Having devised a plan, it was time to act accordingly.
In the following days, Yaya threw herself enthusiastically into the construction of the breeding area.
Under her command, Bobo and the Merfolk became busy.
They cleared out dangerous creatures from the breeding area, reducing the hazard of Blackfish.
Utilizing the Merfolk's talent for burrowing into the mud, they used the sturdy fishing nets of the Bay Domain to artificially create an isolation zone in the mud.
Since no one sold Blackfish, the Bay Domain, despite its wealth, could not buy any.
Yaya opted for a simple and straightforward foolish method, ordering all the remaining Merfolk to catch Blackfish themselves.
Facing this challenging task, Bobo felt a great sense of responsibility and thus came up with an idea.
First, he let the Merfolk eat their fill, allowing each to eat until they were stuffed.
With their bellies full, the Merfolk would not be interested in the lean, meatless Blackfish.
