Light Flash Student Vs Master Possession

As the sun rose and illuminated a field, there were three people spectating from a distance. A disciple and his master could be seen a few feet away from each other as they readied their stance with their daggers in hand. One was a young boy, while the other was a young lady. 

As the pebble which was thrown into the air slowly descended, the pressure being emitted by them increased. 

The instant the pebble touched the ground, there was a flash, and they clashed. 

The lady won the class in terms of power and pushed the boy a few meters back. However, he maintained his balance and pushed back. He leaped at her swinging both daggers in irregular unpredictable patterns. 

As she paired some and avoided other swings, she began to chant. Seeing this, in a near-instant, he froze her legs, then swung both daggers simultaneously. She raised both daggers to parry them. The moment she did, he sent a kick straight at her open belly. The original swings were fake.
