Chi Xue knew Ling Tian extremely well. He knew that Ling Tian had profound attainments in formation runes and restrictions, as well as exceptional comprehension. So it was hardly surprising that he suspected Ling Tian could master runes—which came from the same source as formation runes and restrictions—after observing Rune Cultivators use them. From there, he could work out Ling Tian's plan to stop them from attacking the Rune Cultivators.
If Ling Tian couldn't comprehend the runes, then it wasn't impossible that Feng Xi, the God Realm's foremost formation master, could learn how to use them through observation. That was why Chi Xue believed Ling Tian was trying to stop them from attacking the Rune Cultivators.
It made sense. With Ling Tian and Feng Xi among them, Ling Tian's side had a good chance of mastering the way of runes. That was why they were stopping other God Realm cultivators from attacking the Rune Cultivators. Ling Tian's main goal was to prevent Chi Xue's group from learning how to use runes, so that when the two sides clashed in the future, his side would have better odds.
By now, cultivators throughout the God Realm knew that runes could increase their strength. If Ling Tian's side obtained them, their overall strength would naturally rise considerably, giving them an even greater advantage over Chi Xue's group, who had yet to obtain them.
Even if Ling Tian and Feng Xi failed to comprehend the way of runes, it wouldn't matter. Ling Tian's side still had one last move: attack the Rune Cultivators and seize the knowledge of how to use runes.
Given the chance to monopolize the way of using runes, Ling Tian would naturally choose to do so. What was more, there was almost no risk involved.
