When 28-year-old programmer Lin Yu is chosen by a mysterious System called [Seed of Civilization] during an ordinary late-night overtime shift, he thinks it must be some absurd dream.
That is, until the System informs him in a cold, emotionless voice: in five years, an alien civilization known as the Reapers will arrive in the Solar System. And according to one million simulations, the probability of human civilization surviving is a mere 0.03%.
Faced with this inevitable “civilizational trial,” any one person’s power is as insignificant as a speck of dust. Lin Yu makes the only choice that might change humanity’s fate: he hands over the System and the future to the country he trusts most.
From that moment on, the wheels of history turn with a thunderous roar.
The Pangu Base rises beneath the desert. Controlled nuclear fusion lights an underground sun. The Nantianmen aerospace platform forms a ring of defense around Earth, while Guanghan Palace on the far side of the moon becomes humanity’s eye on deep space. A technological explosion, powered by the whole nation and racing against time, begins in silence.
But this is not a battle China can fight alone. As mysterious warnings save countless lives and revolutionary technologies are gradually put to use, the world’s gaze shifts from suspicion to astonishment. Alongside battle-hardened generals, national scholars, and international partners, Lin Yu and his team struggle amid the undercurrents of global power plays to weave a line of defense for a community with a shared human destiny.
Yet when the countdown reaches zero and the Reaper fleet arrives right on schedule, they discover that the cruelest trial does not come from the stars…
