Inside the Wuyagong Palace, Bai Zhongqi saw the request sent by Kentarou and the others. The fact that household robots cannot use weapons is written into the core source code of all robots. If such an override occurs, the robot is directly scrapped and it cannot be simply explained by a bug.
But rewriting the core source code with Supreme Command is not a problem. In this situation, Bai Zhongqi had no choice but to conscript billions of civilian robots worldwide. Many of these robots are not humanoid, such as some cleaning robots, which may be disc-shaped or barrel-shaped. But any human-like ones have arms that can grasp firearms. Controllers can't control robots; they can only use offensive means to take them down.
