The Dark Zephyr raced across a large volume of empty space and showcased the full speed and agility of the mech. It danced back and forth as it tried its best to evade hundreds of invisible energy beams.
At this stage, the Larkinson Army and more specifically the Hall of Heroes had refined Venerable Tusa's training regime.
The power of an expert mech was so great that the normal intensity of routine practice was completely inadequate.
Over multiple months, the live training sessions became increasingly more intense, systematic and professional.
For example, in order to conveniently provide a huge practice space where the Dark Zephyr could show its paces without exposing anything, the Black Cats specially procured and modified interference bots in huge batches. Thousands or tens of thousands of them could jam and mess up most forms of detection in a volume that stretched out for plenty of kilometers!
