Aircraft breaking the sound barrier and reaching subsonic or even supersonic speeds was easy to understand.
Because whether it was Xu Ruoxi or the other commanders, they had long since grown accustomed to such things.
Back when Earth still existed,
there had been no shortage of aircraft capable of reaching supersonic speeds.
Some Intercontinental Missiles could even reach dozens of times the speed of sound.
As technology advanced, the flight speeds and launch speeds of weapons and equipment reached Sub-Light Speed, or even Superluminal Speed.
Xu Ruoxi and the others could understand such phenomena as well. They had all witnessed them firsthand.
Of course, everyone was also very clear about the price that had to be paid.
Greater speed often meant greater energy consumption.
It also placed extraordinarily high demands on the power structures and construction materials of the relevant aircraft, weapons, and so on.
A speed approaching one light-year per second.
At this moment, it had clearly exceeded the imagination of Xu Ruoxi, Dang Zhongcheng, and even Chewy Candy, Mo Yue, Megatron, and the others.
They were not merely covered in question marks and exclamation marks right now.
Deep down, they even began to feel vaguely worried.
Xu Ruoxi was not the only one to raise concerns about energy consumption.
At this moment, Megatron raised another concern as well.
"Master, if we are to travel at such a high speed, our Star Destroyer Motherships, spacecraft, large Interstellar Mining Transport Ships, and so on will all need to be redesigned and rebuilt."
"Otherwise, given the structural characteristics and material properties of our current ships and aircraft, I am worried they will be unable to withstand the pressure brought about by such high speeds..."
Megatron's concerns, as well as Xu Ruoxi's, were perfectly reasonable.
But Li Chen was fully confident.
"Don't
