Shadowwalker of Itopia

A sudden fire destroyed the plague-ridden city. As a time traveler, Eduardo became the only survivor with the help of the "system" and embarked on the road of revenge. However, as his enemies fell one by one, he began to discover that those who had hurt him were not necessarily evil. On the contrary, those on his side, even the system that claimed "absolute neutrality", seemed to have ulterior motives. "We come from the darkness, speak our hearts with daggers, and seek justice with crossbows. But we must remember that no matter how many times we are bloody, we will always be our original selves." ——The only oath of the first generation Shadow Church
