Jiang Chen didn't know how to react when Lin Lin used the word insurmountable to describe the gap between the two civilizations.
Fortunate? Of course, there was no sign of life activity on the flying object, and it had clearly already been abandoned by its owner for a long time. At least he didn't need to worry about some higher civilization knocking on his door. A colonization ship from 20.5 lightyears away was already giving him a headache. If another unfriendly neighbor dropped by, he wouldn't be able to play this game anymore.
Confused? Perhaps a little. He didn't understand why the flying object was abandoned. If they could create strong interaction force materials, there shouldn't be anything that could threaten them in this universe, at least in his view.
