Back to Terraria,
The human king and the Oni king were busy decoding the message sent by Sam. That was the immediate thought about going to his planet, but after that, they decided that they should first decode the message.
If he requires their help, then he can ask directly for that. At this time, he does not need to send that kind of message to them. Naturally, this is related to other things. This is also a reason that, before doing anything, both of them wanted to decode the message.
They had already told their commander, then every high official, that for a few days, both of them would be busy. Well, if there is only a serious matter, both of them should be informed.
Like this for almost one week, both of them continuously focused on decoding the message. Finally, both of them can read the message sent by Sam.
