What does the last line of Fall of the Moon mean?

My understanding is to fight back. The last line is the dialogue between kc and kc’s mother, the incarnation of lunar consciousness: “Let’s get started.” My understanding is that it is a counterattack against the nano-swarm. At the end of the film, it is also stated that the nano-swarm is not invincible. The film also stated that this is only a small number of nano-clusters that discovered the moon. It does not mean that other nano-clusters will not discover the earth. Their existence is still a threat to human existence. And the film studio also said that there will be a sequel. My understanding is that it will fight back in the sequel like "Independence Day".
