Then there's the T2 Reward Library, which is filled with the creations of second-level civilization technology.
The rewards are abundant, featuring cosmic battleships with fifty percent light speed, space plasma towers, space stations, and so on.
He Xingzhou wanted every item, but in the end, he exchanged for a set of "stellar system automatic patrol satellites."
This set consists of a thousand satellites, capable of traveling at thirty percent of light speed, able to patrol within the range of a star system.
Their main functions include intercepting detection signals from alien civilizations, promptly discovering alien fleets and alien civilization attack weapons; or, within the star system, detecting the movements of the space insect race, etc.
When He Xingzhou discovered that the Solar System was surrounded by so many hostile civilizations eyeing them covetously, he became vigilant.
