Survival for All: Cave Diving, One Gold Entry Per Level

National survival + cave diving + upgrade + gold entry + decisive killing + Cthulhu + invincible style + multiple female protagonists When they woke up, seven billion people around the world were thrown into the underground abyss at the same time. Each person starts with a sealed cave, a set of broken diving gear, a guide rope, and 24-hour oxygen. If you can't find new oxygen, you'll die. If you go into the water without tying a line, you will die. Running around in the water will still kill you. This is not island survival. This is something that will leave a psychological shadow on countless netizens just by looking at it - the hole-in-hell mode. The channel is full of large-scale security breaches every day: Some people can't find their way home just ten minutes after entering the water; Someone's guiding line was broken by the tide, and "the person is still alive, but the soul is gone first" was performed on the spot. And Lin Yuan, when everyone was still tortured by lack of oxygen and darkness and doubting life, he picked up the most unreasonable plug-in in the world - [Rule Modifier]. As soon as the rule entries are bound, the painting style suddenly changes. Oxygen bottle binding [unlimited]; Backpack binding [space]; Workbench binding [Synthesis]. From that moment on, others are trying to survive; Lin Yuan is purchasing goods. But the abyss never talks about mercy. If someone else's daily life is: "I'm responsible for stirring up the mud, and you're responsible for panicking." Then Lin Yuan's daily life is: "You are responsible for crashing the market, and I am responsible for clearing the abyss."
