I Entered a Different World with My Country

The protagonist accidentally opens a space-time gate, and then turns it over to the state in an emergency. After the state takes over, it vigorously develops construction, builds railways, connects high-speed rails, and builds highways! The toll station is erected at the gate of the palace in another world! The demon king who collects angels, destroys beasts, and bombards with energy screams! Zhang Xiaofeng's wise words! I said this is mine, then this is mine, don't you agree? Come on, come on! Look up and see what that is? You first ask me if I agree to the modular space carrier?
