Granddaughter Was Killed? in My Nineties, I Transformed into Shura Demon Armor

[Armor] + [Kamen Rider] + [Blackening to kill all the way! Chen Xiu traveled to a world where everyone could awaken armor and destroy monsters. After awakening the Shura Armor, he upheld justice and fought countless monsters for seventy years. His son and daughter-in-law all died in the battle, and he even retired with a lot of pain, just when he was about to be dependent on his only remaining granddaughter. In the morgue, he saw his granddaughter, who was cold and majestic in the freezer. Just when the desperate Chen Xiu was silent, someone from the Armor Alliance came over and advised him to be more open-minded, not to seek revenge, but to focus on the overall situation! Just as Chen Xiu caressed his granddaughter's tender face, the Shura armor inside his body quietly turned black. [Since justice cannot be stretched, so what if we embrace darkness! The light faded at this moment, and the endless darkness officially descended. "Those who kill will always be killed!" "The overall situation, don't talk to me about the overall situation. What is your identity? Do you deserve it?" "Since light can't give me what I want, why not fall into darkness?" "My heart and my actions are as clear as a clear mirror, and everything I do is righteous!" From this moment on, a Shura Demon Armor who upholds justice in his heart officially arrives! Those sinful and powerful people don't know it yet! A ninety-year-old man is about to let the whole world taste destruction.
