The Soul Penetrates the Remaining Gate and Guards: King of Soldiers System to Build a Dynasty

[Introduction to the opening chapter] Lin Chen went from being a modern soldier to the Great Yan, and became the down-and-out guard of the Qingyan Pass in the Great Yan. Outside the pass, Beidi is watching eagerly, and the cavalry can break through the pass at any time; inside the pass, the food and grass are running out, the soldiers are disengaged, and the prince is lurking in secret, hoping to use the hands of foreign enemies to get rid of him and then hurry up. In a desperate situation, the King of Soldiers system is activated, making iron, training soldiers, setting up formations, and healing wounds, and it can do everything. He burned mountains to open mines and smelted cold iron weapons; he improved military discipline and built an iron-blooded army; he captured messengers at night and uncovered the prince's conspiracy; he fought decisively at Qingyan and defeated the main force of Beidi. From guarding a remaining pass to controlling the entire northern border, from a guard general to the founding emperor. Lin Chen ended the war with war and settled the situation with planning. In this war-torn world, he found his own dynasty path!
