Klaus had no idea when the egg housing the jade ant queen would hatch. However, he knew everything would happen in the vicinity of the Jade Vault.
Of course, since he knew that, it meant the Heavens Court also did, and as such, they would head over to that place. So he wanted to get there first and take what he could before they arrived.
To do that, he needed Crux's speed.
She is an aerial-type beast, so speed in the air is her speciality. Aside from that, she is a demigod, so aside from the other three gods, no beast in the Jade Nest would dare cross her.
Of course, there are those who just can't take a hint—those who are left to suffer for their own idiotic reasons. However, he doubted they would face much resistance on their journey.
Thankfully, it took them three days to get to the vault.
This was even more so because Crux had to take some detours just to evade the domains of the other three gods.
As Klaus expected, they were the first to get there.
