Xia Jinhuan is a blind pianist and the most dangerous experimental subject of Nova Technology - his nerves can invade other people's consciousness. Shangguan Weiyu is a top killer, and his mission is to silence him, but he can hear his rusty heartbeat in the music of the piano. When the military activates the control protocol for three hundred "humanoid weapons", one uses music to encode neurotoxins, and the other uses bullets to calibrate piano key coordinates. Their kiss is a vulnerability in the system, and love is the only virus that can stop the killing.
Intention: One of them uses musical notes to write viruses, and the other uses bullets to debug programs - in this human laboratory, falling in love is the most advanced system invasion.
