This system is a bit cold, a technological powerhouse

[No pretentiousness, no brainless writing, unreasonable early stage, mid-term answer]
[The protagonist needs to grow up, and if I give you 1000 billion, you won't have the thinking and cognition of a boss]
System is not a system?
When the technology tree is full and the map is fully open, can you be able to dominate the universe?
What secrets are hidden in the universe?
Humanity is perishing again,
Or to glory?
Electromagnetic guns, aerospace planes, super aircraft carriers, super mechas, space ports, interstellar warships, and the romance of men are all here.
(An old bookworm for more than 20 years has never read a book. I wrote it myself. The writing style may be poor, but the story is definitely a good one. Xiaobai detours, wants to see the detour, the unreasonableness in the early stage is the pit dug.)
