The System Ran Away! I Had a Body of Steel in Ancient Times

New work by a new artist, mildly enjoyable writing, sorry for the poor writing style. A steel factory worker wakes up and travels to a different ancient time (the timeline is around the Song Dynasty). The game starts with a collapse of the sky and the isolated city is besieged by 100,000 enemy troops. The system that was finally expected crashed and ran away, leaving the protagonist Zhao Ze with a little golden finger, iron will, and steel body (weakened version). The protagonist uses the golden finger to cleverly break the situation and is rescued, fulfilling the last wish of the aggrieved original body. Let's see what kind of success the steel worker Zhao Ze can make in this ancient time with a different timeline, how much change he can bring to the world, and how many people's regrets he can make up for.
