章 815: Advancing By Leaps And Bounds

Time became a blur as several months passed. The better part of a year had now passed since Bai Xiaochun came to the Underworld River Restricted Area, and most of that time, he and his apprentice had been completely immersed in their flame conjuring research. In fact, neither of them really had any idea how much time had passed.

During the day, they would discuss nineteen-colored flame, and during the evening, they would hurry over to the bank of the Underworld River to continue their discussion in the presence of the gravekeeper, making sure to emphasize all of the difficult areas they had been unable to resolve earlier.

Sometimes the gravekeeper wouldn't help them with a certain issue. But when that happened, they would continue to chatter about the matter until he gave in and offered some advice.
