Possibility
"I'll do it if there is a chance that I could, I will." Mu Yue said seriously.
Looking at Mu Yue's determination, the principal was moved. He then said," Alright, I'll have to look at your body using my spiritual energy."
Mu Yue hesitated. If the principal did it, her Extreme Yin Constitution will be exposed.
"Is there something you don't want us to know?" Looking at Mu Yue's expression after saying this, the principal then added, "Your expression tells me even if you don't answer the question. Well, you can trust us I guess… I'm only interested in spells not on other people's secrets. I could kick out Xiao Yan if you want."
"What?! Don't kick me out!" Xiao Yan shouted. Uncovering Mu Yue's secrets were interesting to her. Now that an opportunity was shown to her, she will hold on to it.
"Little brat, secrets can be dangerous to a person. Besides, Mu Yue will not gain any advantage if you know it. As for me, I have to check her body in order to determine the chances of her learning both professions." The principal explained.
"I promise I will keep it to myself. Only we will know and will never say it to anyone. I swear it on my life!" Xiao Yan said.
The principal shakes his head and faces Mu Yue, "I'll be the one who will check your body. Unless we talk about it, she will not know the results."
Looking at Xiao Yan, Mu Yue was thinking if it was fine for her to know. Her secret can be said to be life-threatening to her but hiding it to Xiao Yan will show that she doesn't trust her.
"It's fine for her to know. She was my first friend, I could trust her with this. Besides, she will surely know in the future as we are always together." She decided to trust Xiao Yan. When breaking through, she has to have Xiao Yan by her side to help her. A little bit of research on Xiao Yan's part will surely make her come to a conclusion.
She went near the principal and let him check her body. The principal said, "So this is why. Indeed this is quite dangerous if known by the populace. Having Extreme Yin Constitution is a blessing and a curse."
Xiao Yan's eyes widened, now knowing why Mu Yue's body was always cold. She now knew why Mu Yue's body almost froze when she absorbed a Frozen Yin Spiritual Gem.
"This is interesting! Your Ice affinity originated from your body constitution. Theoretically, you could be a sword cultivator with ice spells, but it will be dangerous. What I'm proposing is that your cultivation base will be the one to convert your spiritual energy to Sword qi while your body will be the one to convert it to Ice elemental energy."
"I have read records about your constitution. When doing a minor or major breakthrough, their body turns cold, and they have to endure it or else they will fail, be a cripple or their body will be frozen. Of course, heaven wouldn't be that unfair. Once they succeeded, their cultivation speed will be higher than anyone's and their spiritual energy are denser than normal."
"You will use the cold generated by your body to form ice spells but this is dangerous! Spell Cultivators have no problem as they will not feel anything when they use spells but you have to endure the cold. Although the pain will be lesser than normal, using it excessively will damage your body."
Hearing what the principal said, Mu Yue, contemplated. Seeing this, the principal then said, "It's fine for you to start learning the basic ice spells. All of the things I said can only happen after you reach the foundation establishment. You have time to think if you wish to continue it. As someone who studies spells and elemental energy, I find this interesting."
"I'll research more about this topic and tell you my findings before the end of the month. I can teach you two for a month before I have to go back. If you wish to still be my student, you must reach Foundation Establishment within a year! I also want you to be one of the students to represent the school six months later in the school tournament."
"You two can leave for now. Look for me tomorrow after lunch as I still have to get some teaching materials."
