Michelle had climbed up the ruins to get a vantage point to shoot from. However, she had very little openings, as the Taijitu was rather well armored. She waited for a moment to strike, then found it when its scales melted. She set her "fire" setting on Artemis to max, then fired a bullet at the exposed weak spot, intending to use the resulting explosion to split the head. If it landed, the explosion wouldn't be strong enough to take it out in one shot, but that didn't mean she couldn't shoot more bullets. She intended to keep firing until her goal was complete.
