Survival Game from the Start: Starting by the Sea

A tsunami and earthquakes sweep across the globe without warning, submerging every bit of land. Everyone is trapped in a survival game. Players must upgrade their shelters and improve their abilities, avoid attacks from native races and other humans, and struggle to stay alive. Every map is full of hidden dangers and opportunities. Grasslands, deserts, hills, rainforests, swamps. Everywhere you look, there are monsters that can kill you and creatures that will eat you. Zhong Zixu starts alone on an island, surrounded by seawater, with a huge sea creature below him eyeing him hungrily. Just as he is at a loss, rows of prompts suddenly appear before his eyes, like cheat codes, showing him where supplies are and warning him when danger is near. Players can obtain large amounts of resources by clearing dungeons, and can even upgrade their shelters by killing one another. Troubles within and dangers without. Everyone is on edge. Many races have survived here. They keep invading and assimilating other races, building civilizations of their own. Humans are like their prey, with no room to fight back. [Update schedule: This story updates daily, with 3,000+ words per day, usually around 11 p.m., sometimes earlier. Extra weekend updates whenever the stars align.] Things to know before reading: 1. The protagonist's golden finger is bound to his shelter. Upgrading it expands the range in which he can search for supplies. [Once the shelter reaches a certain level, it can move.] 2. A progression story. The protagonist is weak from the start, but later the shelter's restrictions are lifted and his abilities improve rapidly. 3. Any similarities between the game maps or items and those in other games are purely coincidental. The other races and native humans will build cities, and humans must reach a certain level before they can go there. 4. The land has many different types of terrain, as does the sea floor, with many resource zones. Sea creatures do not follow real-world depth ranges; the game setting takes precedence. 5. There are built-in dungeon storylines. Clearing them yields large amounts of resources, and each dungeon includes monsters and a plot. 6. Low-level creatures have low intelligence. The more advanced they are, the more humanlike they become. 7. One-on-one romance, with a secondary couple. The secondary couple has a plot twist, so be careful not to ship the wrong pairing. Includes a substitute trope. The seme and uke both have secrets, revealed in the middle and later parts of the story. Please add my new story to your reading list!
