Seeing that Mei was paying attention, Tang Ming continued: "Now, the Machine Empire is basically broken down into divisions. The lowest of these divisions are the numbers. They are mass produced machines in human form. Although they are mass produced they are not to be taken lightly since they are very strong and smart. They are called numbers because they are all given a number for their names. Then there are what they call the names. They are machines that used to be human that have slowly turned their body into machines. Their power is much stronger than the numbers but as they add more cybernetics to their bodies the stronger they become.
