"This was already the third anomalous fluctuation this week."
Hearing that, the other researcher immediately placed the core sample on the analyzer, causing the display to fill with dense spectrograms.
"In the basalt I collected from Shinjuku Gyoen, I detected periodic gravitational disturbances—like someone was tapping out Morse code underground."
In response to this information, Su Wen directly brought up a 3D geological model of the Tokyo area.
Having gained a clearer understanding of part of the future's course, the Scholar's slender fingers naturally circled the location of Shibuya Station.
"Do you remember the theory I proposed while observing [Permanent Magnet-Lannabodu]?
When two underground cavities of comparable mass form a particular angle, they trigger localized changes in spacetime curvature."
He suddenly picked up a steel ruler from the table.
"Like this..."
With the compression of invisible light borrowed from the Many Gates instruments, the steel ruler abruptly bent into a parabola before their eyes, then instantly returned to its original shape.
Jiang Menghan noticed a faint electromagnetic pulse when the ruler recovered, and the monitor's needle jerked sharply.
"Curvature resonance."
"As expected of top student Miss Jiang. Research is so much more efficient with you around—I don't even need to explain the basic principles."
Su Wen praised her.
In return, she gave him a beautiful eye roll. "Mr. Su, what is the point of this experiment?"
"When the gravitational gradients of two spatial regions reach a harmonic frequency, they form a temporary 'spatial passage.'
It's based on research data from a previous civilization."
He paused, then put it more clearly.
"Ancient documents in the [Many Gates-Alijos] library archives concerning Third Era research recorded similar technology."
"You applied to Dean Elda for C3-level reading access?"
The girl immediately countered, sharp as ever.
She knew that information concerning civilizations of previous eras
