บท 599: Leaving Closed Door Cultivation

Wang Lin was not concerned with the battle in the Fire Demon Country. He had spent the last 20 years completely immersed in the celestial spell. Celestial spells couldn't be compared to normal spells; it was very difficult to learn them.

Twenty years was just the beginning for Wang Lin. While immersed in studying the celestial spell and celestial treasure, time flowed by like water, and unknowingly more than 50 years had passed!

There were less than 10 years left until the agreement with the Ancient Demon.

During these almost 100 years of time, in addition to studying the celestial spell and celestial treasures, Wang Lin never stopped imprinting on the scattered devil. During this time, the imprint became even stronger!

After several decades, Wang Lin had only touched the edge of the Stop celestial spell. The requirement for this celestial spell wasn't a certain amount of celestial spiritual energy but one's comprehension of the heavens.
