After I Was Released from Prison, I Relied on the God-Defying System to Kill Across the City

After fifteen years of unjust imprisonment, he returned, his sister disappeared, and his enemies sat high. They took everything away from me, but they didn't know that I worshiped a Tongtian master in prison and was bound to the Heaven-defying System! From today on, I will pave my way home with the blood of my enemies! They say that forgetting memories will make you lose your humanity, but for my sister, I am willing to transform into Shura and kill through this city! I must fight through this city before I forget everything!
