In September 2030, a translucent white tower appeared above the Devil's Triangle. At first, people thought it was a mirage, until numbers appeared on the tower.
With 1,752,000 hours left on the countdown, Earth was safe and sound.
With 1,576,800 hours left, the White Tower became solid, and its countdown was clearly visible. Disasters erupted around the world, the land began to dissolve, and sea levels started rising faster.
Humanity realized that the White Tower was behind the disasters and sent its first exploration team toward it. The assault on the tower had begun.
In September 2180, with 43,800 hours left before the countdown reached zero, the White Tower's exploration progress had only reached 50 percent over the past 150 years, while humanity's living space had shrunk to one-third of its original size.
[Time is running out. A frenzy to assault the tower is sweeping the world.]
A heterochromatic-eyed boy arrived at the foot of the tower, and a deep, mechanical prompt sounded in his ear.
The White Tower welcomes every challenger. Before entering, please remember the rules:
1. All intelligent life inside the tower is equal. No bloodshed.
2. Each person may make three choices on every floor. If you exceed that number, the White Tower will make the choice for you.
3. Please do not use any form of cheating. The overseers are watching you.
Now make your choice: retreat, advance, or... stay.
