If it were the Demon Sutra of another beast, he naturally wouldn't exchange it for contribution points. But the Dragon Turtle was different. It belonged to the twelve Auspicious Beasts of ancient times. If he went to the Tiangong Pavilion to purchase it, he would likely attract unnecessary trouble.
300 points of contribution didn't sound like a lot, but it certainly wasn't little either.
If he exchanged it for an ordinary Demon Sutra, it would definitely be a loss. Only the Demon Sutra of an Ancient Fiend would be worth it.

"No? How could that be?" Su Nan couldn't help but feel despondent.
