Hearing these words, Ji Canghai beamed with joy. The next moment, he took out a black-grey scroll and threw it to Gu Yuan.
"This is a Heart Demon Blood Oath, a special magical artifact refined by predecessors of the Demon Dao. It has a strong binding effect. You only need to write down the agreement on it and then drip your essence blood onto it to make a pact."
"Unless you are a Yang Spirit expert who excels in the Divine Soul, or a Primordial Spirit True Immortal, once this oath is broken, even a Yin God Giant cannot resist it. You'll be tormented as though by five fires burning your heart, heart demons will breed, and life will be worse than death. Have you heard of it, fellow Daoist?"
Gu Yuan had indeed heard of such a thing, a niche magical artifact within the Demon Dao, extremely rare and uncommon. As for its effects, they were just as Ji Canghai described.
He wrapped his palm in True Qi, caught it, and opened it to find a series of agreements already written on it.
