The Rabbit and the Door

Four rabbits stumble into an alien ruin and, after drinking a mysterious liquid, are transformed by runes into two humans—Li Guomin and Wu Meng—along with two undeveloped embryos. They are cast into a simulated world of a 'fake Earth,' living under forged identities in Taiwan's Alishan, waiting for their tickets to the 'real Earth' to activate. Over twenty-two years, they raise twins Li Jie and Li Xiaoyou, hiding the secret of their origins. As the children grow, 'fragments' from different worlds—Simon, a heart surgeon who travels through dreams; Theo, a fugitive carrying a galactic anchor; and Oliver, who awakens from a vegetative state—converge. When all fragments resonate, the 'Door' separating the two Earths finally appears. Li Guomin and Wu Meng must face the ultimate choice: continue existing as fake humans or pass through the Door to become truly human. This is a long vigil of homecoming, memory, and identity. — Description from novelcodex.org
