You damn filthy piece of shit

Lin pulled out the sword from Oren's heart as Oren's body fell limp to the ground and the energy blade disappeared.

The Teachers rushed infront of Lin as they all gasped at the limp laying body of Oren. A teacher rather slim with golden glasses looked at the scene in horror but the horror soon turned into anger, immense uncontrollable anger as energy started to flow out of his body uncontrollably. The teachers beside him turned their attention to him as they were ready to apprehend him.

Lin looked at the slim teacher as their eyes met all hell broke loose as the slim teacher disappeared from his place and appeared infront of Lin using his immense speed of mid 5th ranker. "Teacher Dam wait" Several of the teacher shouted but The slim teacher or Dam ignored their voice.

Dam raised his hand and made a fist as his energy surged into the fist. Lin looked at the punch coming towards him as he forwarded his punch towards Dam. As both of their fist met, A huge force swept out pushing out the crowd of students tens of meter and the teachers some feets away as only the late middle aged man stood his ground as he looked at Lin with a smile and a glint of flash in his eyes.

From the force of the punch, Lin was pushed back some meters back but Dam slammed into the wall behind him coughing out blood. "Uhahaaaaaaa" Dam cried out in fury as he said "you damn filthy piece of shit" and used the back of his hand to wipe the blood. Dam took a stance and he said "Gale fist 2nd stance: Fury of the winds" as he punched the air infront of Lin. The air started to tremble and converge as several invisible wind blade rushed towards Lin.

Lin raised his hand as he opened his palm towards the rushing wind blade as the energy around Lin converged and 7 layered energy shield was produced. The winds blades hit the shield as a massive forced was released from the collision. The crowd of students and teachers shielded themselves from the dust and debris as the limp body of Oren was thrown away from the force but before the body could hit anything the middle aged man caught it.

As the dust and debris settled, The figure of unharmed Lin was revealed as the wind blade only broke through 3 out of 7 energy shield. Lin closed his palm forming a fist and pulled back the fist to his side as the energy shield liquified and became a giant energy fist.

Lin threw his fist to Dam as the energy fist rushed and hit Dam in a small matter of seconds throwing Dam out of the building breaking the walls as Dam lay on the ground of the High school in pain with several bones broken and several parts of his internal organ damaged but not to the point of killing.

The crowd was left in shock, fear and bewilderment. The first time Lin defeated Oren it was surprise but when Lin plunged his sword into Oren's heart it was shock and fear for the crowds but now when Their teacher/ their colleague was left almost dead their dread, fear and shock amplified leaving them all frozen except one in the crowd.
