This is a fantasy world where the Immortal, Demon, and Mortal realms coexist. Cultivators are powerful, while ordinary people struggle to survive. Yun Zhi, the daughter of a family of generals, defended her country in her previous life, only to be betrayed by her fiance and half-sister and die with bitter regret. Reborn at the age of 12, she disguises herself as a foolish young lady and suffers abuse from her own family.
When she was reborn, Yun Zhi unexpectedly acquired the Comeback System and a pocket dimension known as the Immortal Domain of Illusions. The System gives her missions and rewards, while the dimension contains a spirit spring and immortal herbs, allowing her to make pills and artifacts and cultivate spirit herbs.
With the System and her pocket dimension, Yun Zhi can cultivate in secret, refine pills to boost her strength, and complete all kinds of challenging missions.
She may seem meek, but she uses these advantages to break through crises and neutralize poison when her family is in danger, while turning the tables among noblewomen and at court. Others either scheme for power or are fooled by appearances.
In the future, Yun Zhi is destined to rebuild the laws of the world, end the cycle of fate, and become a legend of the Three Realms!
The plot is compact and it's a good read
