When the Li Xing people's silver-gray spacecraft hovers above the steeple of a small-town church, General Li's military coat is still stained with genetic fluid from the laboratory. They want to take half a mountain of ore in exchange for “environmental modification technology,” but who knows whether the silicon-based lifeforms' “cooperation” is just another form of invasion? Worse still, the young scientist Lin Feng's research log contains a scale specimen belonging to Ailiya. The blue-skinned Li Xing scientist is inserting fragments of silicon-based genes into human DNA, while extremists have already set their sights on the laboratory with a bomb. When the first gunshot pierces the glass of the gene chamber, the future of Earth and Li Xing hangs in the trembling hands of these lovers from different species.
