The Grand Supreme Taoist Scripture offers a spiritual contract spell for taming Spirit Beasts. He slit his middle finger, and a drop of essence blood flew out. Immediately Su Chengyu recited a spell, formed seals with his hand, and performed the contract magic.
The Little White Cat raised its paw indignantly, expelling a drop of essence blood that fused together with Su Chengyu's blood.
Under the spell, the two drops of blood merged and then split again. One entered Su Chengyu's forehead, and the other entered the Little White Cat's forehead. A mark appeared on both their foreheads, denoting the completion of the Spirit Beast contract.
With the Spirit Beast contract, the Little White Cat would never betray or harm Su Chengyu, else it would suffer equal backlash.
"Done, let's get in the car."
