A sudden, world-changing event plunges adults aged 18 to 35 around the globe into the sandbox world of Survival War. Chen Bu'er is swept along with them, landing on a desolate island.
Here, survival is the only lesson: by day, he must traverse the jungle and coastline, struggling to find scarce supplies such as water, wild fruit, and ore. When night falls, hungry beasts prowl through the darkness, and the claws of vicious werewolves could tear through his defenses at any moment. Worse still, people on nearby islands launch frequent attacks to seize resources, putting trust and the rules of survival to the test.
Faced with dire odds, Chen Bu'er refuses to back down. With grit and ingenuity, he uses crude tools to build a shelter, gradually reinforcing its defenses and planning its layout. He is determined to turn this barren little island, fraught with danger, into a sturdy fortress capable of withstanding every threat, giving himself and the other survivors a glimmer of hope.
