Of course, the situation had already been reported back home. Compared to their side, detection there was actually much easier. On the other side of the Star Gate, right up against it, there were X-ray machines and all kinds of scanning equipment.
Those devices could see straight through the human body. Even if it hid inside someone, it would not escape detection.
The concern was that these things might silently infiltrate people from Jiang Yan Hai's world and then lie dormant in their world. The Americans had naturally notified them as well.
The Americans understood the seriousness of the matter, of course, and would not take it lightly. They had done a fairly good job in this regard.
There would be all kinds of large-scale detection equipment on the other side of the Star Gate, and there would be many different types.
But there was no need to be overly nervous. These micro-robots were also a type of Octopus Machine. In other words, whether it was these micro-robots or the self-replicating robots produced by Octopus Machines, even if a tiny component passed through the Star Gate, the gate would expand.
So they only needed to monitor the Star Gate's condition at all times. This was the difference between mechanical objects and biological organisms. Biological creatures like Red Mad Wolf had to squeeze their entire bodies through bit by bit before they could expand the Star Gate.
Mechanical creations were different. As long as a mechanical object could be divided into countless tiny units, each unit crossing over individually could increase the Star Gate's diameter.
A micro-robot might only increase the Star Gate's diameter by a few millimeters, while an Octopus Machine could increase it by several dozen centimeters, or even one or two meters.
