Among the three options presented, only the third one aligned with Lin Xun's plan for a sneak attack.
As for the aerial combat, the second option, Lin Xun speculated that the 'Black Thorn Demon' also possesses the ability to fly.
If he were to choose aerial combat, the Valkyrie would not be able to attack while riding, which would essentially reduce the DPS and hamper his attack.
With this in mind, he issued an order to the Valkyrie to attack, subsequently pressing the third option.
[You lifted your staff, murmuring an incantation...]
[The 'Combat Angel - Valkyrie' drew her longbow, gently humming a melody, characters flowing over the arrow's surface, shimmering with white light...]
[She released the bowstring, a streak of white light piercing the darkness, the arrow swiftly aiming at the warm light.]
[With a flash of white light, a dreadful howl echoed from the Abyss Underground to your ear]
[You pronounce the final syllable of the spell.]
