a man in the midst of a battle, a doctor was treating a patient right on the battle field. With a calm expression.

a person noticed in the battle and angrily yelled "you arrogant little bastard! Come face us!" pointed his sword at the doctor.

"please be away...I am still treating a patient." The unknown doctor replied calmly.

the person was about to move but he felt a sword at his neck

"my hyun is treating a patient. Go."
