Zhang San was studying runes in his room, for he lacked enough cultivation resources to support him, and he worried that when the time came to advance from Qi Flow Transformation to True Core to the Sea, he would need pills and spirit grass and have no means to continue.
Thus, he had no choice but to study runes first.
Besides, Wisdom Immortal Zen Master was a master of runes. Teaching himself runes and consulting Wisdom Immortal Zen Master every evening when he encountered problems seemed an excellent plan!
Today, after having lunch at noon, Zhang San continued his rune studies. He had just discovered through comparative analysis that the runes of the Buddhist Sect bore many similarities to those of Taoism.
Zhang San did not know who had borrowed from whom, but by cross-verifying them, he could understand the runes of both schools in half the time, and this method also enhanced his understanding of the differences between the two schools' runes.
