[...]

- So much for the effectiveness of your weapons. Now I will demonstrate one of ours.

- So Retik plans to invade the Earth with his army from the Moon.

- As soon as the saboteur's, he already has their finish softening up our defenses.

- Do you think he'll be able to do it?

- I'm afraid he might.

- I don't know how many men or rocket ships he has, but his atomic weapons are so far ahead of anything we have he wouldn't need a very big army.

- What did you find out about the ray guns?

- Only that they use an element called Lumarium instead of uranium as the base for their atomic reactions.

- They apparently can control the reaction so they will work either as a disintegrating ray or as an explosion like our atomic bomb.

- Well, if their weapons are that powerful it would be impossible for our people to attack them here, even if we had rockets enough to transport an army.

- That's right. Apparently they let us land because they weren't afraid of a single ship, but they would undoubtedly blast it at an invading fleet.

- Then hadn't we better go back right away and warn our people?
