The Horrific Dragon-Class Warships!

Asura spent several hours being briefed on the situation before taking a moment to rest in the unoccupied room for the lord. 

He slept apart from Mu Xue as Lucretia and the Princess stole her from him on the way to the room. Instead, he passed the time reading the shadow elemental tactics.

Occasionally, a shadow version of Asura would appear and perform the book's martial movements, while Asura continued reading as he used the parallel thinking skill to its limit.

'That's not right. Adjust the hip and leg elevation...' 

'Put more force into the movement rather than the blow itself?'

'Can these shadows use my other elements?'

Until exhausting himself and suffering intense pain in his mind, this was how Asura trained before feeling a sense of accomplishment when his shadow emitted ice from the fingertips, creating sharp claws for a moment.
