Steel and Spike: the Rise of the Lords

Erikson, a fifteen-year-old mixed-race boy, lost his parents, had his property taken away, and was bullied in a border village. In an accident, he broke into a secret deal between his enemy and the nomadic prairie cavalry, and was hit by an arrow. When he was about to die, he merged with the knowledge and memory of a different world soul - a college student majoring in metallurgical engineering. After surviving, he was no longer willing to be slaughtered by others. He used a hunting bow and his father's retirement documents to disrupt the earl's trial; he used wood and clay pots to distill spirits to save his arm; he used leather strips and wood chips to make simple stirrups and mounted his horse. He does not believe in God or destiny. He only believed in the temperature of the hammer in his hand and the hardness of the ground beneath his feet. From a miller to a militia captain, from one village to a six-village fiefdom. From a small lord to a king; in this medieval continent with backward productivity, separatist aristocracy, and the struggle between the Holy See and royal power, he has to do more than just survive - he has to set off the torrent of history to crush the ruins of the old era, and use technology and order to reshape the future of this continent. This is an alternate history without magic, system, and Long Aotian. Some are just a young man, using the most solid method to climb up inch by inch in the mud, rust and blood.
