Robot was not a conventional term, but Pasanin's excited description of Yang Yi as a robot was indeed spot-on.
In many ways, Yang Yi was really like a robot. His memory was extraordinary, his computational abilities powerful. Parameters and calculations that normal people might take a long time to remember, he could grasp in a short period.
For shooting, "robot" was actually not a complimentary term.
Shooting with a sniper rifle was complex, certainly not just aiming with the crosshairs in a scope at the target and then firing. In fact, unless the target was exactly in line with the bullet's flat trajectory, aiming with the scope's crosshairs was not possible.
The further the distance, the lower the aiming point needed to be, and then adjusted left or right according to the wind direction. In short, direct aiming was hardly possible.
