Dual identity: Physics professor Ke Yuan appears to be an ordinary scholar, but is actually a core member of the "Gate Project" that secretly studies parallel worlds. There is a quantum device hidden in the laboratory that can open the passage to parallel worlds.
· Unexpected discovery: During a routine experiment, Ke Yuan accidentally received a distress signal from the parallel world "Ke Yuan" and discovered that he in another world was facing a doomsday crisis.
· Mirror World: Ke Yuan traveled to the parallel world Alpha-7 and found that the technology there was more advanced but the society was more repressed. The most shocking thing is that "Ke Yuan" in this world has sacrificed, leaving behind his wife Lin Xia and daughter Xiaoxing.
· Emotional entanglement: Ke Yuan was forced to play another role of himself, and developed real feelings while getting along with Lin Xia day and night. At the same time, he worked with the "Gate Project" team in this world to find a way to save the two worlds.
· Doomsday truth: They discovered that the two worlds are eroding each other at the quantum level, and all channels must be closed to prevent the collapse, and the only way is for someone to stay in the channel forever to maintain balance.
