The British indeed have left, although the ship was much larger and there were many more people, Gao Yang and his group had a gunboat, and that was enough.
Gao Yang watched as the British ship retreated and then slowly sailed out of the harbor.
The leader of the Black Demon turned his gaze to the row of gunboats in front of him and shouted, "Sink them?"
Gao Yang was still watching the British escort ship leaving with its lights on, and the impatient Black Demon leader raised his voice, "Sink them?"
"Huh? Oh, no need to sink them for now. Just leave them be. Looking at it now, there's no need to sink them."
The leader waved his hand and shouted, "Circle the harbor and take out all the coastal defense points."
The 57mm main gun rotated its barrel, fired twice with a boom, and the shells hit the breakwater. The barrel adjusted slightly and fired another two shots, piercing through the sandbags used as a shield, silencing the firing point.
