After lunch, Patrick happily left Li Xuan's Maple Leaf Manor with the mages.

Li Xuan escorted Patrick and his party to the door, and then turned back to the manor, and walked towards the place where Wright the carpenter and his group were.

"Sir. When Wright and a group of people saw Li Xuan coming, they hurriedly stopped what they were doing and saluted Li Xuan.

Li Xuan waved his hand to signal them to continue working, and he said to Wright, "Wright, I need some tools, I hope you can help me prepare them." ”

"Yes sir, please command. Wright replied respectfully to Li Xuan.

"I need a chalkboard, and some lime chalk, and then I'll have some glass beakers with better clarity and some stained sand. Li Xuan slowly opened his mouth and said the same.

After hearing this, Wright said with an embarrassed face: "Sir, can you explain more clearly on the blackboard, and there are lime pens." ”

Li Xuan patiently explained: "The blackboard and lime pen are used together, which can be a thick wooden board dyed black, fixed on the wall, and then used the lime pen to write and draw, to be able to erase it. ”

Wright thought for a moment and continued to ask, "Sir, you said that you may find a lime pen in a tailor's shop, where there are white lime cakes for marking on fabrics. ”

"That's right, it's that white lime cake, and I need to make it the shape of a finger. Li Xuan said to him.

"Yes sir, I think it should be fine. Wright said stiffly.

"These things, where you need gold coins, go to Boris and tell him, these things are what I want. By the way, by the way, Boris said to clean up another room on the third floor to make a classroom, and the blackboard was moved to the classroom and fixed on the north wall of the room. Prepare some more chairs and put them in the classroom. Li Xuan said.

"Yes sir, I'll go to Butler Boris. Although Wright couldn't quite understand Li Xuan's reason for doing this, he still responded.

Carroston, in Stanlini Castle.

Evening soon came, and the Stanlini family gathered in the dining room to eat dinner quietly.

Orin looked at Vivien, who was absent-minded, and asked her: "Vivian, I have been absent-minded since I saw you today, can you tell Dad, what happened to you today?"

Vivien didn't seem to hear Orin's culture, still holding a piece of baked wheat cake with a fork in a bit of distraction.

"Vivien. Orin asked her one more time.

"Ah, father, did you call me?" Vivien replied to Orin as she regained her senses.

"You've been absent-minded today, has something happened?" Orin asked.

Vivien thought for a moment and asked Orin, "Father, do you know that there is something around us that we can't see, touch, feel, and real? ”

"I can't see, I can't touch, I can't perceive, and I don't know there's such a thing. Orin shook his head.

"I know, Vivien, it's the wind!" Luma replied to Vivien, putting down her knife and fork.

"The wind can't be seen, can't be touched, but it's real, Vivien. Luma said with some smugness.

Noah thought for a moment and said, "Light and shadow are also real, we can see them, but we can't touch them. ”

"Time is invisible, intangible, and intangible, but real. "It was Cole who spoke.

Orin had a happy smile on his face when he saw everyone talking so enthusiastically, he hadn't been so happy in a long time.

Viscountess Mandy smiled and asked Vivian, "Vivian, it's time to give the answer." ”

Vivien shook her head: "You're all right, there's another thing that the teacher said today, called air." ”

Mandy looked at Vivien quizzically and asked, "Air?"

Vivian frowned and said, "The teacher said that the air is all around us, and that we can breathe without suffocating because of the air, and that the flame can burn because of the air, and he also mentioned a word called 'gas'. ”

Orin frowned and asked, "Gas?"

Vivian nodded: "The teacher said that many things have three forms, just like water, it freezes when it's cold, and it turns into steam when it's hot. ”

Orin said thoughtfully, "Mercury comes in these three forms. ”

Vivien nodded: "The teacher mentioned mercury, and he also talked about things related to temperature, water becomes water vapor to heat up to 100 degrees, and mercury needs 350 degrees. ”

"350 degrees?" Orin was a little surprised, he thought he knew a lot about mercury as he often went to the mercury refining room, but he didn't know how much mercury had to be heated to turn into mercury gas. And Li Xuan has already quantified the temperature. Using water as a standard is a great theory.

"Vivien, why are you so distracted?" Mandy asked her gently.

Vivian said a little aggrieved: "The teacher said that the magic element is like air, it can't be seen, touched and not easy to perceive. If you want to become a magician, you must be able to perceive the magic element, and perceiving the magic element requires talent. Mage Sid can sense air elements, Mage Diribair can sense water elements, Mage Binge can sense fire elements, and Vivien can't sense any element. ”

Mandy glanced at Orin, who smiled and said to Vivien, "Vivian, didn't you know about this before? When you were ten years old, didn't we take you to the Magic Guild to try? And have you forgotten? Master Li Xuan said that as long as you learn, even a farmer can become a magician, isn't Vivian as good as a farmer?"

Vivien pouted, looking still very unhappy and dissatisfied.

"By the way, it seems that Knight Egger also went to Master Li Xuan's Maple Leaf Manor today. Orin asked Vivien.

Vivien nodded and said, "Uncle Egger is also taking a class with Master Li Xuan today, and he, like Vivien, is also a person who has no magical talent. ”

As if she had suddenly remembered something funny, Vivien suddenly laughed happily, then looked at everyone mysteriously, and slowly asked, "Do you want to play a game? Let's guess the age of the teacher? Dad, you guess first." ”

Orin smiled, thought for a moment and said, "30 years old?"

Vivien shook her head.

Luma said, "25 years old?"

Vivien shook her head, then looked at her mother, Mandy.

Mandy smiled slightly: "I'm only 35 years old Master Li Xuan?"

Vivien continued to shake her head.

Several people guessed several times, but they didn't guess correctly, and finally Luma asked Vivian anxiously: "Vivian, just say it quickly, how old is Master Li Xuan?"

Vivian put away the smile on her face, slowly opened her mouth and said seriously, "466 years old." ”

Everyone looked at Vivien in disbelief.
