Sword of the Dawn: the Last Visionary

Ryan Dawn is dead. After his death, a soul from another world took over his body and stood up from the burning manor. This man named Zhang Chengyuan used Ryan's body to create a cannon that was not of this world, and blasted the attacking Templars to pieces. Ryan's sister Erin recognized the truth immediately. But she didn't run away, nor did she hate it. She said: "If my brother's body is still alive, then he is not really dead yet." She said: "If you want revenge... I will accompany you." From then on, she called him "brother." It's not a replacement, it's a continuation! This is a story about a lost stranger and a girl who lost everything, working together to seek revenge, find the truth, and change the entire world in the process.
