Shen He transmigrated to the cultivation world and became a disciple with the most useless mixed spiritual root. Spiritual energy dissipated on the spot before it could travel even three inches. In the depths of her frustration, she happened upon Introduction to Basic Formations and discovered that the energy pathways in its formation diagrams were remarkably similar to the wiring diagrams of military weapons systems from her previous life.
Others used spiritual energy to inscribe formations. She had none, so she had to carve them by hand. Stroke by stroke, she carved her first incomplete Spirit-Gathering Formation into a discarded spirit stone, and the useless Shen He embarked on a path of formation cultivation unlike any that had come before.
At the end of that path stood her senior sister, Ji Xiyue, who sheltered her from every storm. Shen He swore she would protect her, and not a single person would be lost.
