[Reject AI to be beaten by hand + It's better to have no brains and it's even better to have brains + Survive without suffering + If you don't have a virgin, you won't be a hero + You'll be among thousands of flowers] Without warning, mankind's fate is trapped in the underground abyss. Suffocation, darkness, unknown creatures, seven-day catastrophe... Difficulties come one after another, and every second is a countdown. But the human spirit Lu Feng successfully bound the Earth's Son system, while others dug in the dark and fought to the death for half a bottle of water. However, he has unlocked various miraculous buildings, gathered loyal followers, tamed dangerous creatures, held countless resources, unlocked technology step by step, and revived the glory of human civilization. ———————————— "I feel it.
