"Camp Commandant, how did humans explore such stable wormholes in the past?" Ling Jiu could not help but ask.
"Just like the past!"
The camp commandant looked at Ling Jiu. "We will send a robot over first to test the stability and compatibility and the environment on the opposite end of the wormhole."
"Whether the wormhole is really stable?"
"Whether we can pass through it?"
"Is the other side of the wormhole on a planet, or in space?"
"If it's an alien planet, what is the environment of the planet like? Does it allow human survival? Are there any intelligent and high civilizations on it?
"So on and so forth!"
"This series of questions all needed to be carefully explored, you can't be too careful about it."
"After all, compared to the vast universe, humans are just too fragile!"
