"Bichen moves under my spiritual power. You are still fighting me."

With that information coolly delivered, Bichen descends on Magnus, still with those quick, brisk sweeps through the air, inexorable. The glow of its blade is growing brighter, and frostier, as Lan Wangji continues to prevent any slicing qi or damaging sword glare from releasing itself. When Magnus blocks or parries, he will likely note the absolute firmness of Bichen in the air, the way crossing blades with it feels like crossing blades with a statue. That said, Lan Wangji is enjoying the dance of this enough to be focused more on the beauty of each swing than on specifically trying to disarm Magnus.
