In the first year of Jingkang, the Jin army trampled through the Central Plains, the mountains and rivers were broken, and the people were displaced. Shen Yan, a modern social animal, accidentally traveled through time and became the most unworthy son-in-law of the Su family in Bianjing. He was treated with cold eyes. In a desperate situation, he awakened the golden finger of Western magic. The fireball technique can burn the enemy's armor, the shield technique can block sharp arrows, and he can also integrate Chinese magic to give birth to heaven-defying supernatural powers. Shen Yan has an optimistic personality and never complains about others. He relies on magic to counterattack step by step and protect the Su family. The gentle and virtuous Su Qingwan was the first person to stand beside him, and the couple joined hands. When Western magicians were living in exile in the Song Dynasty, when magic collided with gunpowder, Shen Yan, as a son-in-law, turned the tide from collapse, helped the building to collapse, rewrote the shame of Jingkang, and created the iron-blooded glory of the Song Dynasty!
