When Chen Cheng returned to the dormitory, he looked at the broken wooden bed board that Fini had left in the corner.
Chen Cheng moved the dilapidated bed board from the corner, then drew the iron sword from his waist. After gesturing with his hand to roughly determine the size he needed, he began to chop.
Don't be fooled by the pitted and unappealing appearance of the iron sword; it had been sharpened when Chen Cheng left the cave where he lived.
With a few swift swings of his iron sword, wood chips flew, and the plank was soon cut to the size he needed.
After blowing off the remaining wood shavings and placing the plank on the wooden table beside him, Chen Cheng took the brush he had "borrowed" from Isabel and began to write the symbols for a vision chart on the board.
Actually, the moment Chen Cheng thought about making a pair of glasses for Melinda, he had remembered this bed board in his dorm. It was perfect for making a vision chart to determine Melinda's actual eyesight.
The idea of making glasses for her came about after he learned that Melinda was nearsighted, and it was the kind that even magic couldn't cure.
Perhaps magic in this world had developed too powerfully in certain aspects, leading to less emphasis on simpler auxiliary tools, like these nearsighted glasses.
Although Chen Cheng didn't know what a real vision chart looked like, he managed to draw one based on his memories and his current vision during the lunch break.
Looking at the rather unstandard vision chart in his hand, Chen Cheng still revealed a happy smile. This was the second item from his previous life that he had made himself, besides the firearm that Scorpio had taken.
Looking at these familiar items, it felt as if they were constantly reminding him of where he came from.
It was precisely these reminders that prevented his memories from getting lost while his body was still young.
He put the wooden board away, and at that moment, a knock sounded from outside the door. Fini's voice came from outside: "Lazy pig, get up! Class is about to start."
Chen Cheng tidied up the wood shavings in front of him, then hurried to open the door, only to see Fini standing at the entrance with a pout.
"I really don't know who's the master between you and me. I have to bring you food, and I have to wake you up to get out of bed. Honestly."
As she spoke, Fini let out a slightly aggrieved hum.
Chen Cheng felt quite awkward hearing this. He then looked around at the other students and the servants by their sides. The servants were cautiously doing their duties next to their masters, carrying their still groggy young masters to class.
Although he was a servant, he truly hadn't fulfilled the duties of a servant to Fini.
While this might sound a bit demeaning, when he put himself in that position, he felt quite embarrassed.
Seeing Chen Cheng's slightly awkward expression, Fini, the little loli, quickly calmed down. She then urged Chen Cheng to go to class.
"It's good that you know you were wrong. Hurry up, I don't want to be late."
As they were leaving, Chen Cheng suddenly asked:
"Which teacher is teaching our afternoon class?"
"Oh, that. I forgot to tell you, the afternoon class is Magic History, and the teacher is also Teacher Melinda."
Upon hearing this, Chen Cheng immediately returned to the dormitory, found a tattered curtain, tied the vision chart to it, and slung it over his shoulder.
This way, after class, he could directly test Melinda's vision, saving him the trouble of going to her office and being gossiped about by certain people.
As for these "certain people," Chen Cheng was naturally referring to Isabel, who had always disliked him.
In fact, the misunderstanding that morning had truly hurt Chen Cheng. Although his mental age was over thirty, because more than twenty years of his previous life had been spent mostly on studying and research, his psychological state regarding external emotions like love was still akin to that of a teenager.
Due to his mental age and Melinda's previous intimacy with him, his youthful heart had indeed been somewhat touched. However, the words from Isabel and Melinda afterward had delivered a harsh reality check.
His heart, which had just begun to flutter, was abruptly halted.
Fini saw Chen Cheng carrying such a wooden board and wanted to ask about it, but thinking that class was about to start, she merely glared at Chen Cheng, telling him to behave himself and not to cause trouble that would anger Teacher Melinda, then urged him to hurry to the classroom.
The two arrived at the classroom, and when the others saw Chen Cheng return completely unharmed, they were all astonished. In their eyes, anyone called away by Isabel never came to any good. Although this teacher seemed very gentle during class, she punished those who disobeyed very severely.
They had heard that Isabel once taught a senior class where a student, relying on his father being a viscount, acted recklessly in class. In the end, this student fell into Isabel's hands, and she directly ruined his future path of magical cultivation.
Then, looking at the broken wooden board Chen Cheng was carrying on his back, they wondered what this peculiar slave was up to. However, they were certain that Teacher Melinda would scold him severely when she entered.
It would be best if Teacher Melinda became disappointed in him and sent him away.
They didn't want the matter of their noble sons studying alongside a slave to be spread, which would be a disgrace to them.
These noble youths harbored various thoughts, none of them wishing Chen Cheng well.
Soon, the class bell rang. Melinda, with her usual gentle smile, walked into the classroom. Her gaze was then drawn to Chen Cheng, sitting at the back with the wooden board on his back.
She wanted to say something, but after thinking for a moment, she didn't speak and continued with the lesson.
The students who were eagerly anticipating a spectacle were all disappointed when Melinda said nothing.
The most disappointed among them was Coles, who wished he could go up and kill Chen Cheng, to wash away the humiliation of being insulted by this lowly slave.
Especially after being mocked with duck calls by those people in the cafeteria at noon, the memory of that scene intensified his killing intent towards Chen Cheng.
This Magic History class greatly broadened Chen Cheng's horizons. He wanted to truly understand the development of magic in this world systematically and comprehensively, and this class was an excellent choice.
After Melinda finished recounting the life of Peron, the first legendary mage known in the continent's records, the class ended. For these young ones, their formal classes for the day were over.
From then on, they could go to the library to read magic books that interested them or go to the magic laboratory to practice the basic introductory magic they learned that morning.
At this moment, Chen Cheng stood up and called out to Melinda.
"Teacher Melinda, please wait a moment."
At the same time, Melinda also had something to say to Chen Cheng.
She nodded at Chen Cheng, signaling him to come over. The two stood at the front of the classroom.
Chen Cheng unstrapped the wooden board from his back and put it down, then revealed a happy smile and said:
"Teacher Melinda, this is part of the surprise I prepared for you..."
However, before he could finish speaking, Melinda's pretty face flushed with anger and she reprimanded him:
"Brown, is this the time for you to be thinking about these things? I don't need any surprises. The reason I gave you this opportunity is because you are diligent and eager to learn, do you understand?"
Well, with that, Chen Cheng realized that Melinda had truly misunderstood him. She really thought he was trying to pursue her, a younger person pursuing an older one.
Although Chen Cheng's mind was that of an adult, he was still a little hurt by being misunderstood like this.
He showed Melinda the front of the vision chart and said:
"This is a vision chart I made. With this, we can determine your eyesight. Then, I can grind corresponding lenses from transparent crystals to restore your vision. This is also my way of thanking you for your guidance and cultivation of me."
Chen Cheng's words were quite polite and formal now, and he no longer mentioned any surprises.
Fini, who had been watching from the side, now understood why Chen Cheng had asked her in the morning if he could take the magic crystals. It turned out he wanted to repay Melinda.
This little loli was still young and didn't understand what Melinda had just said. She was happy to have a slave like Chen Cheng who knew how to repay kindness.
The other classmates who stayed to watch were wondering what these lenses Chen Cheng mentioned were. Could this thing possibly cure Teacher Melinda's eyes, which even magic couldn't heal?
However, Melinda regretted her words after she said them. Hearing Chen Cheng's formal and somewhat stiff words made her little heart ache even more.
Chen Cheng didn't say anything else. Holding the vision chart, he stepped back to a sufficient distance, propped it up, and asked:
"Teacher, are you ready?"
Melinda only then snapped back to attention. She knew it wasn't a good time to say anything else, so she could only nod to indicate she was ready.
Then, Chen Cheng had Melinda cover her left eye and use only her right eye to point out the direction of the 'E' he was indicating.
After the left eye, it was the right eye. After repeating this a few times to confirm, Chen Cheng roughly calculated the myopia degrees for Melinda's left and right eyes.
Although the results might have some deviation, the glasses could be adjusted after they were made.
After Melinda's test, Fini's playful side emerged. She stood in the same spot Melinda had, covered her eyes, and asked Chen Cheng to test her as well. Chen Cheng readily agreed.
The onlookers, who hadn't seen Melinda scold Chen Cheng, became interested when they saw this somewhat amusing vision chart. They all expressed their desire to be tested.
After all, this was the first time they had seen something that could assess a person's physical condition without using magic.
But Chen Cheng didn't have that much time to play with them. He gave the vision chart to them and briefly taught their nearby servants how to use it before heading to the library with Fini.
However, after Chen Cheng left, a short, young boy sitting on the shoulders of a large man looked with a sinister smile at the departing Chen Cheng and Melinda, who still stood on the podium with a somewhat sad expression.
Coles then had his large companion carry him through the crowd. Although he wanted to kill that lowly slave Chen Cheng, he was also very interested in the vision chart Chen Cheng had created.
