Double-Sided Cultivation: Blood Shadow and Nightingale

"A little red between the eyebrows means a heart that will last for thousands of years" - this is the evaluation of Lin Wan'er, the senior sister of Immortal Sword Peak, in the world of immortality cultivators. No one knows that this unparalleled iceberg beauty is actually the full-level killer "Blood Shadow" Chen Xinyu. Her figure is as tall as a green bamboo, her skin is as good as snow, and her eyebrows are like a painting. When the moon-white flowing cloud skirt dances in the wind, even the most delicate peonies are eclipsed. But under such an alluring appearance, there is hidden strength that makes the entire world of immortal cultivation tremble: the invisible flying blade takes people's lives while talking and laughing, and the immortal sword changes the color of the world and kills it. When Chen Xinyu woke up, she found that she had traveled to a world of immortal cultivation where the weak and the strong preyed on the weak.

During the day, she accepts assassination missions, harvesting lives in the name of "Blood Shadow", and looting the target's secret treasures, magical spells, and treasure maps; at night, she transforms into a "Nightingale" and sneaks into major ancient tombs and forbidden areas in search of lost skills and magical artifacts. Relying on the Immortal Flying Blade Technique, the Immortal Countless Clone Technique, the Immortal Disguise Technique and the Immortal God Walking Technique, she walks on the edge of life and death, and every mission is a huge gamble. But when she discovers that her assassination target during the day is mysteriously connected to the ancient tomb she explores at night, a bigger conspiracy gradually emerges... In this world full of calculations and killings, can Chen Xinyu use his dual identity to play with the world of immortality and become the ultimate winner? In this world,
