No. 105

One early morning in 2026, the 105th decimal place of pi changed from 9 to 0. Not a hack. It's not a calculation error. Someone—or something—is rewriting the underlying code of the universe. Theoretical physicist Lin Lan discovered that all supercomputers in the world calculated the same "wrong answer" simultaneously. Immediately afterwards, the speed of light slowed down by 0.0003%, Gravity occasionally failed, and a city's cars collectively levitated for three seconds. And outside the cantilever of the Milky Way, an originally blank area began to emit regular pulses, like the universe reporting an error. She was forced to form a team: a retired old professor, a chatterbox from the observatory, an internet-addicted graduate student, a deep space communications engineer who was partially deaf in the left ear and completely deaf in the right ear, and an ex-boyfriend in military uniform. They discovered a fact even scarier than the end of the world - our universe may just be the product of a "mathematical test." When a clerical error occurs in a fundamental constant, the only way to correct it is to click "Backspace" on the entire three-dimensional space. 72 Hours countdown. Find the real answer to that number before it is deleted. But that answer may not be 9 or 0. In a sentence: There is a bug in the universe, and the price of fixing it is to delete the entire reality.
