The product of the military's "Twin Gu" experiment - two embryos sharing the same nervous system split into independent consciousnesses "Lin Yu" and "Lin Qiao". Thirty kilometers apart, we can feel each other's pain. We are not brothers, but closer than blood; we are not lovers, but we are more obsessed than love. When separation becomes a luxury and integration becomes a trap, they must find a third way between "mutual devouring" and "common annihilation" - and the final answer is a "fourth way" that even they themselves cannot predict.
Intent: A story about 'how to choose to be a human being in the designed destiny'. Two experimental subjects sharing a nervous system completed the evolution from weapons to humans in twenty-seven years. They are not brothers, not lovers, they are... Each other's destiny. In the end, they chose to burn together, to ashes together, and to become complete ordinary people who no longer remembered each other. This is the ultimate tragedy and the brightest hope.
