He favored his concubine and I cut off my wealth. Everyone in the mansion was in a panic.

[House Fighting + Power Stratagems + A Cool Story with a Strong Female Lead + Two Clean 1v1s]
Shen Qing followed her mother's dying words and married into Yangling Marquis' Mansion to become the mistress of the house. She abided by her duties and did not fight or compete. However, her husband brought his sweetheart into the mansion in a high-profile manner less than a year after the marriage. The ceremony was even more grand than that of her, the legal wife.
Shen Qing, who had always been obedient since she got married, suddenly realized: her mother was wrong. A woman's gentleness and kindness may not necessarily bring respect and understanding from her husband's family, but may also bring endless demands and unscrupulousness.
Since this is the case, there is naturally no need for her to be a gentle and virtuous mistress of the Marquis' Mansion.
If a concubine is spoiled and arrogant, and does not know the difference between high and low, then give her a few more slaps to let her know who is the master.
If the husband is two-faced and two-faced, then expose his true colors and make him no longer pretend to be a glamorous and bright man.
The mother-in-law is cold-hearted and only cares about money, so she should be cut off from money supply so that she can no longer maintain her airs as a noble lady.
As for Shen Qing? Of course, after she has completely cleaned up the whole family, she will take a million family fortune and marry Bai Yueguang in a grand manner!
