Lin Jingque, the heir to the summoning technique of the Zhengdao family, always went wrong during his practice - every time he summoned, what appeared in the formation was not the spiritual pet beast, but Ye Wujiu, the sworn enemy of the Demon Sect. This absurd binding originates from the ancient "soul-drawing technique", which is designed to lock generations of enemies into fateful companions. What's more terrible is that every time they are summoned, their body parts must be randomly exchanged.
When her right hands were swapped, her sword-holding hand would uncontrollably condense demonic energy, and his sword-wielding palm would suddenly perform sword techniques; on the day their left eyes were swapped, she had a glimpse of his forbearance in the dungeon, and he had a glimpse of her tenderness under the peach blossom tree. When the hearts exchanged, she heard that the heartbeat hidden in his chest was not just murderous.
A century-old feud follows them everywhere, but the brand of soul-drawing is getting hotter day by day. From being forced to share their senses to facing enemies back-to-back on the battlefield, from the mutual exclusion of "devils" and "hypocrites" to the tacit understanding of "now we are a complete combat force". When the key to unlocking the contract appeared, they understood: Those misplaced spiritual orifices had already caused the two hearts to quietly grow roots of bondage in the cracks of hatred.
This is a call that began with a mistake and ended with a destiny.
