Returning from His Own Father Who Died in Battle? I'll Change My Mother's Husband for Her

Forensic doctor Pei He returned to the Qian Dynasty and became a sickly peasant boy. Just after he was born, his biological father died in battle. The best grandpa, greedy for the pension, decided to sell her beautiful mother-in-law to a country gentleman as her concubine! Pei Hegui bound the technological deduction system and decisively separated the family and divorced his mother. Five years have passed, and on the surface, he is a sick young man who will collapse in the wind. Secretly, he made firearms, established a chamber of commerce, and became the richest man in Daqian. Even the current prince had to call him Emperor Master! His own mother was also raised by him to be graceful and noble, and was about to marry the chief minister of the dynasty. Just before the wedding, the biological father who was rumored to have died in the war for five years came back alive! Not only did he not die, he also made military achievements and was granted the title of Marquis of the country. He was surrounded by the enemy's and his own little princess. The scumbag father said: "Remembering the past friendship, I will reward your mother with the position of concubine, so you can reluctantly join the house and become a concubine." Princess Xinhuan covered her mouth and smiled sweetly: "You country bumpkin, please don't soil the floor tiles of the Marquis' mansion." Pei Hegui smiled. He turned around and tore up the sickly disguise, took out a divorce note and slapped the scumbag father hard on the face. "The Marquis has recognized the wrong person. This is the wife of Ming Yuan, the chief minister of the dynasty, who is marrying." "By the way, the entire Marquis Mansion under your feet is my property." "Now, take your little princess and get out of my territory!" When the master of Emperor Daqian, the master of Dark Night Pavilion, and the richest man in the world made mistakes one after another. The arrogant scumbag father completely collapsed and knelt in the heavy rain, crying and begging for forgiveness.
