The young naval tactical genius Arthur Wilander was demoted to the "Anvil Fleet" because of his outstanding talents, but unexpectedly encountered the Cthulhu pirate group equipped with the strange "Old Dominator Cannon". When the "chaos foam" that can swallow up ships spreads on the sea, only the "golden section" found by Arthur combined with ballistic mechanics and the "silver bullet chain" of the engineer's old pipe can compete. In the blood and fire of the siege and counter-encirclement, Arthur discovered the ancient sadness and secrets hidden in the eyes of the pirate leader Serena Chaoge. No longer satisfied with destruction, he is determined to uncover the truth that the pirates are actually descendants of exiled Atlantis. Faced with the iron laws of the navy and the whispers of the deep sea, Arthurs used ballistics as his pen and tactics as his ink to write an unprecedented path in the stormy seas - prompting the navy and pirates to sign the "Deep Sea Channel Co-Governance Agreement", using wisdom and courage to quell the millennium feud and become the true "Stop the Waves".
