After all, the people piloting these planes are all robots.
That's right, Lin Yi doesn't use real people. Considering real people have thoughts, it's hard for them to keep things hidden or stop them from spreading information.
But robots are different. Once you assign them a task, they follow through without deviation, and if you don't expose them to certain things, they won't record them.
Because of this, as more planes were pulled in, Lin Yi didn't stop; you could say that for every plane that arrived, he dismantled and rebuilt it.
By evening, all these planes had vanished, and the promised number from Ouyang Lei had been completely fulfilled. Presently, Lin Yi's System Space stored 200 brand new planes.
Of course, bringing all these planes to the ancient society might seem plenty for now and definitely sufficient, but one hundred years from now, their quantity might not be enough.
