The Tenth Book by Fu Sheng Meng Ying

The heroine was an ordinary modern woman who unexpectedly transmigrated into Perfect World. Having died with a grievance in her previous life, she was reborn here and met Shi Hao, growing up alongside him. However, in order to maintain their rule, certain forces in the Immortal Domain continued to oppress the lower realm. The heroine and Shi Hao faced a difficult choice: should they rely on the power of darkness to grow stronger quickly, or stand by their principles? Meanwhile, the heroine was still weak and burdened by the emotional wounds of her past life, struggling in both love and battle. The vast gap in power between the Immortal Domain and the lower realm, along with the unequal distribution of resources, held back their progress. Just as their feelings for each other deepened, a rival suitor appeared, and the villain stirred up misunderstandings that made Shi Hao doubt the heroine. With the Immortal Domain's attack on the lower realm growing ever more imminent, they had to become stronger in the limited time they had to protect it. Drawing on the wisdom she gained through rebirth, the heroine supported Shi Hao as they cleared up their misunderstandings and overcame their trials. In the end, they successfully protected the lower realm, established themselves in the Immortal Domain, and won love and the admiration of all.
