The archipelago is surrounded by ruins, and thousands of islands are separated. Pirates plunder, aliens parasitize, and civilization hangs on a thread. Lu Chenzhou is just a small bookkeeper at the Xingyue Port Terminal, but unexpectedly he can pick up "time fragments" - predict three seconds in the future, or look back five seconds in the past. He used this ability to save a drowning sea-born businessman, but was told that every time he saved a person, he owed a cause and effect. When the debt reaches one hundred and eight, everything about him will be wiped out by natural disaster level karma. To make matters worse, the people he rescued were mixed with phantoms that feed on emotions, which led to the secret society "The Ruins Keepers" coming to visit - all supernatural beings must maintain a triple bunker, and if their identities are exposed, they will be hunted down by both humans and aliens. Lu Chenzhou was forced to deal with the docks, associations and pirates. He used prejudgment to avoid assassinations, relied on "ghostwriting myths" to tamper with prophecy scrolls, and reversed the plan to make the smuggling leader who framed him suffer the consequences. But the number of causal debts was approaching one hundred and eight day by day... During a certain rescue, he found that every time he paid off a debt, the estimated time would increase by one tenth of a second. If you want to stay alive, you must continue to save people. But the next person to save may be an enemy, or a friend who is destined to die.
