Little Xue slightly opened her mouth, staring dumbfoundedly at her father, "Are... Are you kidding?"
She stammered, "Ten... ten fingers, huh?"
Su Yu nodded slightly, explaining, "The ten fingers are connected to the heart, and only with the blood of all ten fingers can the hearts connect and complete the contract. If he ever intends to harm you, just a mere thought from you will rend him with immolation. Even if you want him dead and he's cultivated an Immortal Body, he will still be turned to ashes by your will. But as long as he always remains loyal to you, he will be safe and sound. The power of your bloodline can also help him mend the last remnant of his soul quickly. When one day you reach the Divine Level in cultivation and wish to end this contract, you may choose to dissolve it automatically. Once the Blood Covenant is formed, his life and death will be in your hands."
