It's obvious that this is an advanced rune transformation mastered only by the noble families. It's very mature and perfect.
Although Gao Xuan has perfectly integrated the Five Elements Runes, he hasn't done much in deducing the changes of the rune seed. Because this requires time accumulation, requiring countless experiments to polish.
He doesn't need to do this at all, as long as he analyzes the essential secrets of the rune seed. Whoever uses high-tier rune power transformation, he can learn it just by watching once.
Just like now, before Yu Hong'en has even drawn his sword, Gao Xuan has already completely seen through his divine soul and rune seed.
It should be said that the opponent's sword seal is very clever, much stronger than the Ice Seal that Gao Xuan deduced himself.
Gao Xuan didn't hold back, and first copied the opponent's sword seal entirely.
Yu Hong'en was completely unaware of this. He stopped twenty steps away from Gao Xuan.
