Sephiroth War

An exploration spacecraft sent back a text before it disappeared: We are in a cage. An army sent a text back to the world before disappearing: We found a way out, But the enemy was also found. We can't see the enemy, we can't touch the enemy, physical attacks are ineffective, repeat physical attacks are ineffective... Cui Qianzhong, commander of the Chakna 2257 Group Army, telegraphed to the headquarters: The enemy will not die, the enemy keeps polluting the space, the enemy keeps resurrecting corpses, the enemy is not a god, and we can win. Our troops destroyed the crossing gate. Beware of the living.
