Soon, their two competing representatives were chosen.
Four mechas were pushed out. To ensure that the competition was fair, Li Lanfeng asked the people from the Disciplinary and Investigation Committee to board the mechas and enter a command for some changes and then hide the command. The competitors would find the command and make changes to the mecha according to the command.
This was the debugging skill of a mecha engineer. Before the mecha operators boarded their mechas, the mecha engineers must debug the mecha so that the mecha was in optimal condition. Any mistakes in the system must be found and be deleted.
Debugging was a common work done by the mecha engineers. The best way to assess how good a mecha logistician was was to see how fast one could change the weapons and equipment of the mechas during a battle.
