The difficulty in forging the appearance isn't too high; Xiao Moshan can manage it himself, but the core… that's significantly more challenging.
Fortunately, Qu Jianlei's mechanical manufacturing competence isn't low, and he has plenty of tools, so he tried his best to imitate.
The slots on the arms of these mecha warriors are for reading the core, and they'll sound an alarm if fake documents are detected.
There are three types of alarms: basic ones with light and sound alerts, advanced ones where the mecha warriors actively trigger a base alarm.
However, just with sound and light alerts, these guarding warriors can take action.
The red light flashed a few times and then stopped. Qu Jianlei sighed in relief: finally, no sound went off.
Xiao Moshan was quite clear about the process and also felt relieved.
The two mecha warriors exchanged glances, "Why did it look like a red light at first… and then like green?"
