As Starfleet traveled through the maelstrom of time and space, flashes of nuclear explosions from seven years ago swept past the portholes. Xiaoman stood on the bridge, the scorch marks on her wrist resonating with the Earth's magnetic field. Chuyun discovers that the mutated nerves of the robotic arm are being repaired in reverse, growing human skin tissue. Dr. Shen stares at the countdown panel - 03:47 on October 23, 2023, the exact moment Dr. Lin initiates the consciousness upload experiment.
The landing capsule lands in the ruins of the Shanghai Quantum Lab, and the crowd sees the young Su Wanqing rushing into the building with her daughter in her arms. The mechanical girl's remaining consciousness suddenly accesses the communicator, "The time anchor must be destroyed or reincarnation continues forever."
The ruins of the lab surfaced in double time: seven years ago, Dr. Lin activated the Hongjun system on the top floor, while the present-day team found the metal ring prototype in the basement. Xiao Man's light pattern energy penetrates the space-time wall and sees Su Evening's husband tampering with the AI code - he's hiding a backup of his consciousness in the Hongjun core.
Chu Yun uses his robotic arm to pry open the safe, which contains baby clothes stained with milk powder. Dr. Shen detects miniature time anchors embedded in the clothing fibers, the very origin of all reincarnation. The Commander of the Resurrection Body suddenly shows up to grab it, and is shot through the energy core by Su Evening's Void.
Dual time and space began to merge, and Dr. Lin's laboratory instruments operated automatically. Xiao Man injects light pattern energy into the Hongjun mainframe, and the screen flashes a global nuclear power plant overload image. Chu Yun disassembles the time anchor points with his robotic arm, each line connected to the sensors of the baby's warming box.
Dr. Shen converted the anti-matter bomb into a time stabilizer, and the moment the countdown went to zero, all the metal rings lit up at the same time. Su Wanqing's silhouette picked up Xiao Man as an infant and gently placed him into the unactivated cloning chamber. The lab dome cracked open, revealing the uncontaminated starry sky from seven years ago.
After the bright light engulfs everything, the fleet returns to present-day Earth. The Shanghai Quantum Laboratory turns into a memorial, with the unactivated Hongjun prototype displayed in the window. Chu Yun's robotic arm is fully restored to a human arm, and Dr. Shen discovers a new plaque on the memorial wall - Su Wanqing's husband's name is engraved at the top of the "Guardians of Humanity" list.
Xiao Man's wrist burns disappear, and the light pattern energy turns into a normal birthmark. The Commander's data fragments are integrated into the Memorial's mainframe, and Dr. Lin's final message is played on a loop: "Please don't ever activate me."
