Chen Yan, the adopted son-in-law, was humiliated by the Su family and was scolded as a waste by his mother-in-law Zhao Yuhua in public every day. No one knows that he once defeated an enemy of 30,000 with 3,000 cavalry at the border, and now he is just waiting for an order. His wife Su Wantang watched with cold eyes, the housekeeper Lin Su secretly informed him, and Huo Wujiu, the Minister of War, regarded him as an ant. Until the beacon fire in the north was ignited, millions of cavalry marched together, Chen Yan wore black armor, and crushed the lintel of the Su Mansion - this time, it was their turn to kneel and listen to him.
