What Ves needed to do was to find the root programming and sneak in a few extra codes.
However, Ves faced a huge issue at this juncture. He wasn't adept in the special programming language used to instruct a neural interface on how to manage the man-machine connection. He couldn't just write something like 'make the mech pilot unflinchingly loyal to the 6th Flagrant Vandals mech regiment, oh, and also forget about your past loyalty to Prince Hixt-Klaaster'.
The phrase described the desired outcome, but to get there Ves needed to manipulate the machine language into an exact set of code that specifically resulted in such an outcome. To do that from scratch, Ves needed to develop an extreme amount of expertise in the inner workings of the human mind in order to be able to target the specific brain sections related to loyalty and recognition of specific individuals and groups.
