Chapter 690: Chapter 690: The 1000th

Hearing Master Ding say that the person inside the magic formation could last at most three years, Yang Xiaotian's heart sank.

It was almost certain that the person inside was Yuan Wei.

But three years—such a short time.

It would pass in the blink of an eye.

How could he rescue Yuan Wei?

Yang Xiaotian asked Master Ding if there was any way.

"To break the Desolate Primordial Black Tortoise Demon Formation is almost impossible, however, to save someone, there's still some hope," Master Ding said, "Two hundred flasks of Ninefold Heavenly Tribulation Thunder Water, and I can help you bring the person out."

Two hundred flasks of Ninefold Heavenly Tribulation Thunder Water!

Upon hearing this, Yang Xiaotian immediately shook his head.

This method was unworkable—he had been struggling to find any Ninefold Heavenly Tribulation Thunder Water for years without news. Where could he find so much in three years?
