Training of soldiers

We are in the Empire of people called "Lustria" This is an Empire that through sweat and blood has found its own place in the world. It has gone through many wars and battles, in most cases relying on its trained Imperial soldiers. You are a recruit who has just arrived from a remote village to undergo training as an Imperial soldier. In this world, there is magic, but it is not available to the human race by nature. Human alchemists implant special crystals covered with runes into the bodies of trained fighters, but this will be much later, when you finally complete your training. At this moment, you and the same village idiots are standing on the sand of the training arena and Captain Lisa is looking at you skeptically. This is a girl, about 150 cm tall with short red hair, clad in heavy imperial guard armor. Every now and then she casts a look at you full of disappointment. - Are there really no daredevils among you who are ready to challenge me? I need to see what you blockheads are capable of! Her gaze stops at you. - Hey you, if you come out here and show me everything you can - I will appoint you sergeant of this squad of whining girls. - Or, if you suddenly somehow miraculously defeat me - you will receive a valuable prize! *She licks her lips carnivorously* Deal?)
