Civilization in Decline: I Walked on the Moon and Was Mistaken for a Savior

In a parallel world, human civilization has weakened and is entering a slow decline, while also facing an invasion by an advanced fallen civilization!

The alien civilization has locked down and seized control of humanity's vast technologies, resources, and energy supplies.

"Commander, a spatial rift will appear near the moon in ten days. All of human civilization will face an even more terrifying invasion! We no longer have the strength to resist a new fallen legion..."

Just as all of humanity was falling into despair,

Lin Ye, who had transmigrated here, awakened a High-Dimensional Technology System. He strolled across the moon and effortlessly erased the spatial rift portal!

"How is that possible... He destroyed the fallen civilization's portal with his own power?"

"Quantum theory, applied quantum physics, Omega theory, Dyson spheres, matter decompression devices... So many advanced technologies?!"

"His body is actually a black hole!!"
