Starfall City
A bald old man was teaching his students.
He was in a classroom. Standing in front of his 24 students, he introduced Mana to the children.
"Mana is a very strange and mysterious energy that is around the world around us. It's not known when Mana first came to our world or if Mana has existed since the dawn of time. But one is clear. Without Mana, there would not be any cultivators. Our entire world will become completely unrecognizable."
One of the students from his classroom raised her hand. Seeing the face of the student who raised her hand, the old man's expression softened.
"Yes.....!!"
The little girl excitedly stood up and asked. "Fa....I mean, Teacher, is it true that Mana enters our body when we breathe?" The girl little almost let everyone know of their secret. But she was able to correct herself.
