One Piece: Throne of Kuroshio

This is the era of hegemony when Rocks dominates the sea and Roger has not yet become king. Cyrus Venn has no system and no idea of ​​the future. What he initially owned was a body locked on a gold tribute ship in the sky, a gunpowder cabin that could explode at any time, and an account that could write human life as "natural loss." In order to survive, he stood on the powder keg and negotiated with Rocks; in order to no longer be regarded as a consumable, he began to record every name, understand every ship's movement, and borrow every cannon. From the abandoned son of the tribute ship to the bottom member of the Rocks ship, from the temporary commander of three dead ships to the helmsman who can sink the entire fleet into the sea of ​​thunder, he does not rely on foresight, but only relies on exposing risks and bearing the price again and again, and turns a group of defeated troops who do not trust each other into companions who are willing to return to each other. After the storm in the Valley of the Gods, the old order collapsed. Roger, Whitebeard, Golden Lion and Cyrus are the four heroes chasing the sea; after Roger's death, a new pattern of four emperors came. Cyrus replaced the throne that originally belonged to Kaido, but Kaido did not retire - he stood under the same flag as the vice-emperor, allowing a pirate group to have two emperor-level combat powers at the same time. When the world government, navy, dragons and heroes all thought that the sea could only be divided forever, Cyrus had already begun to keep accounts for the final war. This time, what he wants is not to become the Pirate King. Instead, there is only one throne left in the entire sea that can make rules.
