After My Rebirth, I Protected the Entire City by Relying on Substitute Marriage Contracts.

In my last life, I was the only descendant of the Tianzong, but I was tricked by my stepmother and step-sister into marrying into the Lin family on my sister's behalf. Eventually, I had my meridians cut off, watched the whole city being swallowed up by the blood evil, and died miserably on the night of the blood moon. When I opened my eyes, I went back to the day of my wedding. In front of me was Lin Mochen, the abandoned son of the Lin family who was rumored to be violent and cruel, and who married for his brother. Behind me was my original family who planned my life. Above my head was the blood moon catastrophe that was about to come in seven days. Everyone thought that marrying into the Lin family would lead to a dead end for me, a loser who had been kicked out of the house. But no one knows that I hold the inheritance of the Tianzong in my hand, can draw evil spirits, solve centuries-old problems, and break bad debts. Stepsister Bai Lian is pretending to be pitiful? I directly revealed the trump card that she was manipulated by the magician and let her suffer the consequences. The evil stepmother is playing dirty tricks? I ended her dream of wealth and made her pay for the evil deeds that killed my mother. Stabbed in the back by a trusted master? I have a righteous heart, clean up the door with my own hands, and take back everything that belongs to Tianzong. Only that paranoid man, who was trapped in a surrogate marriage contract just like me, became my only fellow traveler. He blocked all the evil knives for me, protected me with his direct lineage from the Lin family, and held my hand tightly when I collapsed: "If the sky falls, I will carry it with you." The seven-day blood moon counts down, and a century-old feud is dead. We use marriage as a contract and unity as a seal to change our fate against the will of heaven and suppress evil spirits. Later, when the blood moon disappeared and the sun rose, someone asked us where we wanted to end up. He held my hand and walked through the world: "Wherever she is, my home will be. If she wants to protect the common people, I will accompany her for the rest of my life."
