Then a similarly antiquated piece of paper image appeared next to it with a few lines of introduction written on it:
"The 'Incredible Soglier Conjecture — Arc Light Step Forward Slash' is a charge attack skill uniquely created by Soglier, requiring Mecha weapons to be either a saber or combined sword class."
"During a Mecha assault, it utilizes the Mechanical Master's visual lock-on to perform minute directional changes with the weapon, maintaining the Mecha's front facing the enemy's side at all times. The charge posture resembles the spread of an electric arc, with astonishing uncertainty in position! It is also the preceding move to unlock advanced skills. For detailed records, please proceed to the seventh floor B29 physical bookshelf area and consult the paper version of Soglier's notes, with the code BSG-22195."
