Interstellar Sign

Because of the beginning of the energy mine, a small civilization has reached unprecedented heights after more than three hundred years of development. When the bad news came, tens of thousands of interstellar civilizations attacked. They defended it, but because they were too strong and more advanced civilizations were afraid of their development speed, they began to feel that they could defend this civilization.
