Lü Yongchang silently watched the orange-yellow cursor.
This was the second time he had seen a so-called secondary-risk technology.
He had also begun to grasp what that designation meant.
A secondary-risk technology was most likely a technology beyond a civilization's level.
Whether it was the [Thought Imprint] or the so-called incomplete [Four-Dimensional Optical Brain], both were stripped-down technologies from a higher-level technology tree.
The incomplete [Four-Dimensional Optical Brain] needed no further explanation.
Humanity had only mastered the [Thought Imprint] by taking a shortcut with the help of the [Nus Civilization].
Compared with the complete [Thought Imprint] mastered by the Cleaners Civilization, it too was effectively an incomplete technology.
As for the danger... the risks of the [Thought Imprint] went without saying, while those of the [Four-Dimensional Optical Brain] lay primarily in the research process.
Just imagine.
Without the observational data from the Imperial Fortress, how many failures would Human Civilization have had to endure before discovering the underlying principles? How many more would it have taken to build a usable four-dimensional architecture?
Human Civilization could never have sustained research on that scale.
Even the combined resources of the entire Pan-Human Federation could not have withstood that rate of consumption!
In just a few years, Zero's computing power grew by leaps and bounds.
This was undoubtedly excellent news for Human Civilization-its strength had increased across the board!
It was different from other civilizations.
With several cheat-like advantages working in tandem, Human Civilization's development had even begun to accelerate.
In Earth Calendar year 3767, the data and experience gained while researching the [Four-Dimensional Optical Brain] brought another breakthrough in spacetime theory.
That breakthrough also drove advances in grand unified field theory.
Like someone climbing into the sky by stepping on one foot with the other, the Human Federation's technology experienced an
