Two years after departure, in Earth Calendar year 11502.
For human civilization, which had mastered level four curvature and could travel at 10,000c, the Andromeda Galaxy was indeed a little small.
In just two years, human civilization and the Silicon Stingray Civilization had traversed a region spanning over ten thousand light-years.
During this process, human civilization's brand-new micro-universe gradually filled up-an entire fifteen hundred medium- and large-scale stellar systems gave human civilization the confidence to undertake its coming journey across 54 million light-years.
The long journey had yet to truly begin, and the fleet had yet to leave the Andromeda Galaxy, but research at the Human Federation Academy of Sciences had already made a significant breakthrough.
To ensure the stability of the micro-universe itself and the densely packed celestial bodies within it, many research projects at the Academy of Sciences had stalled.
This was not difficult to understand.
Even the cutting-edge technology of level five and level six civilizations could cause quite a stir, let alone that of a level seven civilization.
After their advancement to a level seven civilization, research into dark matter and spacetime was even less straightforward.
Take the Dark Matter Cannon alone.
With enough power to destroy an entire large-scale stellar system, could they really mess around with that thing inside a micro-universe?
How was that any different from detonating a nuclear bomb in their own home?
For precisely this reason, under Lü Yongchang's orders, research during the voyage focused primarily on theories and branch technologies.
Five hundred years of grueling research had allowed human civilization to unlock nearly the entire trunk of the level seven technology tree-the current tree resembled a bare trunk, with barely any branches, let alone leaves.
To dispel the fog at the top of the level seven technology tree and advance
