It's obvious.
These two wormholes are one-way random wormholes created by the Insect Race Civilization. Eggs will emerge through the wormholes and fall onto planets, thus bringing Doomsday.
Logically speaking.
There should also be a wormhole nearby Water Blue Star from the Insect Race Civilization.
But the Doomsday of Water Blue Star lasted more than 212 days, so it might have been that Water Blue Star experienced Doomsday first, and then after a certain period, the wormhole automatically dissipated, so the duration of a one-time wormhole is about 300 days?
The duration of this one-time wormhole is already quite long.
The resources consumed to create wormholes, from most to least, are as follows—
Bi-directional Stable Wormhole, Bi-directional One-time Wormhole, One-way Stable Wormhole, One-way One-time Wormhole, One-way Stable Random Wormhole, One-way One-time Random Wormhole.
The "One-way One-time Random Wormhole" is the cheapest.
