Cygnus Invasion: Summon a Secondary Civilization at the Start

Cygnus invades the earth, and mankind faces destruction. Cygnus Level 2 Civilization and Earth Level 0.7 Civilization are impossible to fight. They are not on the same level. Fortunately, Lu Yu summoned the second-level civilization system at the beginning, and he was tied with Cygnus Technology at the beginning. Prince of the Swan Kingdom: Impossible, this is absolutely impossible. Doesn't the earth only have a level 0.7 Civilization? Where are the people from the Intelligence Bureau? Take him out and shoot him. Emperor of the Swan Kingdom: Could it be that the First Emperor of the Xia Kingdom was resurrected? It turns out that he pretended to be dead for thousands of years to build the earth into a level 2.5 Civilization. The Supreme Emperor of the Swan Kingdom: No, son, this is definitely not just a level 2.5 Civilization, this is a proper level three civilization or above. Everyone: It's over. I thought the earth was a little brother, but unexpectedly, it became our big brother thousands of years ago. We can't afford to offend, we can't afford to offend...
