The Wet Nurse Takes Away the Child, and I Come Back from the Ashes.

In her previous life, Shen Lingyi married into Uncle Anyuan's Mansion, supported her husband Xiao Chengyou to become a nobility, took care of the family, and raised a pair of children. However, she became terminally ill before the age of thirty-five. Before she died, she found out that she had been chronically poisoned by her husband and their children's nanny, Liu. The so-called children were not her biological children, but the illegitimate children of Liu and Xiao Chengyou. Her two biological children were exchanged at birth, and their lives and deaths are unknown. Unwilling to have her dowry divided by her enemies, she set fire to her house before she died, burning herself and all her life savings. When she opened her eyes again, she returned to the age of sixteen, when she was looking at Xiao Chengyou, the eldest son of Uncle Anyuan's Mansion. Unable to completely refuse the marriage, she turned her attention to Xiao Chengjing, the second young master who died early in her previous life. In the previous life, Xiao Chengjing was originally the underappreciated second son of the uncle. He was a naughty boy. Later, he joined the battlefield and earned a marquis for the Xiao family with his military exploits. However, he died in the battle against the enemy. In his new life, Shen Lingyi will marry him, support him, protect him, and also borrow his sword to cut off all the bad ties in the previous life.
