My Sister Was Killed, I Transformed into Shura to Take Revenge

"Xiaochuan, save me..." "Xiaochuan, I'm so scared, where are you?" That day, Shen Chuan saw his sister's desperate blood letter before she died! On that day, Shen Chuan had no way to redress his grievances. Not only did his sister who depended on each other die unjustly, but she also had to bear all kinds of infamy! Hatred and anger filled every drop of blood in Shen Chuan's body. He stepped into the feared restricted area alone, just to seek a possibility of revenge. Seven days later… A scimitar, a cloak, and a solitary shadow. He transformed into the Demon King Shura who was feared by everyone! Since there is no justice in the world, then I will seek justice myself! He cut his enemies to death with his sword, and those who used to be superior knelt neatly in front of his sister's grave, just praying for a chance to live! "When my sister begged you? Who gave her a chance?" "My sister died unjustly, who will give her justice?" "What did my sister do wrong to deserve to be treated like this by you?" "If I forgive you, can my sister survive?" "Don't forgive, never forgive..."
