The fleet didn't go to Nagiu Port but headed straight for Puzhou Port instead, mainly because the 2 large carriers and 2 fast battleships needed to return to the shipyard for necessary inspections.
It was only upon arriving at Puzhou Port that they received reliable information.
The fleet that had departed from the Bulan Kingdom and was bound for Nara Fortress didn't head south; instead, it turned back to the Bulan Kingdom in Biscay Bay.
Thereafter, the Bulan Royal Navy began laying mines in the Dover Strait.
Strictly speaking, it was actually expanding the range of the minefield and increasing the density of mines deployed.
Not long after the outbreak of the great war, the Bulan Royal Navy had laid mines in the Dover Strait and used naval mines to prevent the Tiaoman troops from launching landing operations.
Naturally, the results were very good.
