The System's Little Mistress

Shen Yue, a top modern-day researcher, opens her eyes to find she has become the young madam of the Marquis of Jing'an’s household, with a newborn baby and a portable laboratory System to boot.

Her husband, Xiao Yunchen, may have been forced into the marriage, but he is upright and dependable, and cares deeply for her and their child. Her long-lost parents, the Chancellor and his wife, have also given her the familial affection she had sorely missed. She thinks she can settle down and raise her child in peace, until her precious son, Tuanzi, starts calling his father at just four months old and can even understand the System’s voice!

The System assigns missions that earn points, which can be exchanged for medicine or used to analyze anything. Tuanzi has “superpowers” of his own, making him both her sweet little comfort and a “troublemaker.”

With a traitor poisoning people in the household, political enemies making things difficult at court, and a plague sweeping the capital, Shen Yue uses her System and foils their schemes, making waves in ancient times with her modern knowledge:

“Marquis, there’s poison in this tea. Shall I get you a cup of ‘immortal water’ instead?”

“Tuanzi, stop messing around in the System shop! I’m nearly out of points!”

From the inner courtyards of the manor to the imperial court, she protects her baby, takes down villains, and builds a career, all while enjoying sweet moments with her cold-faced marquis. But one day, Xiao Yunchen watches her and Tuanzi recite the periodic table, then asks in a low voice, “Just how many secrets are you two hiding?”
