At this moment, he is already utilizing the 'Spirit Light Communication' inherited from the Sunbird to coordinate tactics with Anfa and 'Ian' for the upcoming siege on Ian.
It sounds as if Aina indeed knows The Unyielding Fortress very well. The Unyielding Fortress that Hiliard passed down to Ian does have some weaknesses and flaws that can be countered by the techniques he mentioned.
This Imperial Grandson Aina is truly honest; he really dares to trust his allies.
This is what Ian's core is thinking at the moment, and within a breath, Anfa and 'Aina' move forward together with Aina, forming an inverted triangle position, protecting Aina at the rear, as a sharp aura rises.

Known for their ever-changing strategies, Yanjiang and the City of Knowledge are now observing, which actually places more pressure on the Ghost Valley Knight.
