Ximen Tiesuan was stunned for a long time, unable to react.
Sasa and the others did not disturb Ximen Tiesuan. After all, this was something Professor Ximen had researched for most of his life, and he was an authority in this area. Suddenly, a few youngsters came to tell him there were errors in his research. It's something hard for anyone to accept.
Fortunately, Ximen Tiesuan wasn't one of those stubborn old folks stuck in the past. After digesting the news for a moment, he composed himself.
"Just now you said... Yan Luo can fly?" Ximen Tiesuan looked at Yan Luo in disbelief.
In the ancient texts passed down the generations, there was no mention of the Saints among their ancestors being able to fly. To Ximen Tiesuan, 'Saints can't fly' was common knowledge.
