635 Chapter 338: Unexpected Harvest

Call Heaven Scripture?

Hearing Su Nan's words, the middle-aged man in the lead finally came to his senses after being shocked by the instant kill of the demon, saying:

"Great God, to obtain the Call Heaven Scripture, one needs to sign a contract with the Destiny Society. The method is directly imprinted in the mind using a special method by the Destiny Society, there is no secret manual, and we can't even write it down if we want to."

"There are such protective measures?" Su Nan frowned.

He thought that the Destiny Society deliberately spread the ancient scriptures, naturally choosing an easily spread method, such as providing a rubbing copy. Now it seems he thought too simply.

Could it be that the Destiny Society was trying to prevent others from researching the Call Heaven Scripture like he was?

Or was it that the Call Heaven Scripture itself had no problems, but the issue was with the contract that was signed?
