He gave orders to that end at once, and the cart was laid hold of and drawn out of the square and down the street, Olox accompanying it. "I had no idea," the king drummed on his word-box, "that there were any people in the solar system with so much wealth and so little power with which to guard it. I’ve got the other three kingdoms of Njambai pretty well under my thumb, and the regent I leave behind to boss things will have an easy time of it. Quite possibly I may conclude not to come back to Njambai. This other star has natural advantages which we do not seem to have here, and may prove a more comfortable place in which to live." Professor Quinn was shivering, like a man with an ague. He proceeded to use his talk-machine, and the words shook under his unsteady fingers. "What you are thinking of, your majesty," ran the professor’s words, "is only the wildest of dreams." "I have had dreams before, and wild ones," the king’s word-box rattled off complacently, "and I have made them come true. It shall be the same with this. I am a conqueror, and I come of a line of conquerors." "There are millions upon millions of people on our planet," persisted the professor, despairingly. "They could hurl these countless numbers against you faster than you could slay them with your zetbais." Key 7 of the royal word-box gave a screech of contempt. "Suppose we draw a line of zet," the box added, when the derision had died out, "imprison groups of those countless numbers and then wipe them out by detachments? How would that work?" "The atmosphere of Earth is different from that of Mercury," continued the professor. "You cannot draw zet from the air of our planet." "Thanks for the hint," replied the king. "We will take an ample supply with us and charge the atmosphere with it. Then we shall have a store at hand whenever the need develops." While the king was using his word-box with two of his hands, he was rubbing the other two together with ill-concealed delight. "Conditions there are absolutely unknown to you, your majesty," persisted the professor in a frantic endeavor to turn the king from his designs. "You will be brought face to face, at every turn, with situations that will puzzle you and be fraught with danger. All the nations of the Earth will combine against you." "Let them combine!" was the monarch’s answer. "I hope they will display sufficient strength to make the campaign exciting. I will capture this Earth of yours and rule over it! From one end of it to the other I will make it mine! I have long felt that Njambai was too small for the proper exercise of my wide abilities." "This is your world," the professor thumped angrily on his word-box, "and you have no right to meddle with any other planet." That caused the king to turn his keen eye on the professor, and to keep it there for a full minute.
