Hua Country was already an interplanetary civilization in the prime of the Nano Era when it came to aerospace.

Yet it was not a normal interplanetary civilization. Its development was severely lopsided.

After all, time was pressing. They had to focus on advancing the long-range voyage project and constructing defensive works within a limited timeframe, draining enormous national strength in the process.

They had gained none of the benefits of space development, pouring everything into the construction of the Kunlun Mirror and almost single-handedly trying to salvage Earth's fate.

This could be seen from the fact that although they had invented Mirror Steel, a material at the pinnacle of nanotechnology, they could not even mass-produce the High-Temperature Superconductors that should have appeared during the prime of the Nano Era.

The observers from various civilizations, despite their advanced technology, still had a mentality of "why don't they just eat meat?"

A Dark Wing Clan official asked a self-righteous question. "Why didn't the Earthlings build the Kunlun Mirror in low Earth orbit? That would greatly reduce the cost of the entire project."

From a god's-eye view, Earthlings' choice did indeed seem strange.

Deploying the Kunlun Mirror in low Earth orbit would have made it easier to transport materials and energy.

Placing it so far away was far less effective. Diffraction of electromagnetic waves would allow some rays to bypass the Kunlun Mirror and bombard Earth.

Seeing that he was evaluating the matter purely from a physics standpoint, Mu Yuan sighed. "Then have you considered... that building such a magnificent project nearby, visible whenever people looked up, would cause panic in other countries?"

"What?" The Dark Wing Clan official was stunned.

Then he understood. The Gamma-ray Burst would arrive at light speed, and Earthlings had no way to learn of it in advance.
