Lin Sinan, a geographer, unexpectedly discovered that the slight beat of the magnetic needle's declination caused ripples in time and space while observing Gu Sinan. The degree of change strangely corresponds to the shift in topological dimensions. He joined hands with the stubborn physicist Gu Xianyin, using the theory of geomagnetic reversal as a spear and topological manifold mathematics as a shield to build a "Geomagnetic Space-Time Management Bureau" to bring disordered travel into scientific orbit. Faced with the prediction of magnetic pole reversal and the challenge of space-time folds, they weaved a stable path, guarded order, and finally used a "Space-time Topology Protection Convention" to reshape the rules of space-time exploration, and set the course of the universe in the geomagnetic rhythm and topology mystery.
