Ten days had passed since the end of the feast, and the sensation caused by the white wolf's fireworks had gradually subsided, and most of the foxes had returned to their daily lives, working at sunrise and sunset, with little interest in rune knowledge.

On this day, in a somewhat cramped room, five foxes were standing on tiptoe to look overhead, and they were making such strange gestures not because they were practicing dance, but because the white wolf was standing on the ladder above them at this moment.

"Fortunately, this lighting circle is not too badly aged, and it will be almost as good as new if it is repaired a little. The white wolf landed on his two hind legs, his two front paws against the ceiling, and returned the part of the stone carved with the illumination circle to its original position, feeling that the stone had been stuck in the internal interface of the ceiling, the white wolf put down the two front paws, and the stone was firmly embedded in the ceiling and did not fall.

"Absinthe, you go and try it, it should work. The white wolf said to one of the foxes gathered below, pointing to the wall in the distance.

That fox was Absinthe, Qingyue was by his side, and the other three new foxes were all young foxes like the two of them, looking at the rune circle on their heads with interest.

Most foxes have indeed returned to their daily lives, but there are still a small number of foxes who are attracted by the white wolf's rune technology and choose to follow the white wolf to learn rune knowledge, and these five foxes are all of this small group of foxes.

The white wolf is now teaching for free, because the foxes provide him with food and shelter, and there are special people to serve him, if he still wants any payment, it is a bit too much, the white wolf does not like to owe others things, he simply takes this knowledge as a return to the foxes.

Today, the white wolf prepared a lighting circle maintenance class for these five foxes, and many of the lighting circles where the foxes live have undergone aging, and the teaching materials are simply sufficient.

Hearing the words of the white wolf, Absinthe immediately walked to the wall, and entered a trace of fire element into the conduction rune on the wall, and the fire element entered the interior of the lighting circle along the conduction rune, and the thunder element output rune was activated, and the thunder element was output, and after passing through other runes, it was stabilized, attenuated, and finally turned into a stable light, illuminating the entire hut.

"It's really lit!"

"It feels so much brighter than before!"

The foxes below saw this scene and were amazed, not long ago, the light emitted by this lighting circle was still a little dim, but now it has become extremely bright, this is not the first rune circle that the white wolf has brought them to repair, the change from dim to bright has often been staged in front of the eyes of these foxes these days, but at present, they still feel that this matter is very fresh.

"The reason why the color of the light output by the lighting circle becomes dim is that the water element erodes the fire element storage circuit, causing the fire element to not be able to excite enough thunder element, and the light will naturally dim, if this goes on for a long time, the lighting circle will even go out, and it will never light up again. Like a teacher, the white wolf patiently explained to his students the principle of aging, which he had explained many times, and seeing that there was no confusion in his students' expressions, he understood that the foxes had mastered this knowledge, and it might be time to explain something more complicated.

"Regarding the concepts I talked about, if any of you don't understand anything, you can ask me, our next step is to go deeper and quantitatively analyze each of the lines on these rune arrays, and then the course will be much more difficult than the previous one, I hope you are mentally prepared, and now the class is over!" The white wolf then waved his hand to a few foxes.

"Teacher~Goodbye~" The foxes bowed to the white wolf, and the white wolf returned the salute, this is the ritual that the white wolf stipulates to be carried out at the end of class, the foxes thought it was very strange at first, but slowly got used to it, the reason why they did this is because the white wolf had to do these things when he was in school, and he had to stand up after class, saying goodbye teacher, this is what the white wolf has been doing since elementary school, and he is moving some of the teaching methods of that world to this side.

"If it weren't for my illiteracy, you would have experienced the fear of being drowned in a sea of work. This is the only thing that makes the white wolf feel a little unhappy, although he can now communicate with the foxes with wind language, but he doesn't know the foxes' words yet, he is now studying hard, in the matter of text teaching, Qingyue and Absinthe are the teachers of the white wolf, and they will come to teach the white wolf to read and write every day.

After class, there is a fox who left directly, and the white wolf also understands his situation, and it seems that he ran out secretly while his mother was not paying attention, and if he didn't go back early, he would encounter some trouble if his parents found out, so he always went first, but another white wolf student would always help him ask questions, so the white wolf was not worried that the fox would not be able to keep up with his progress.

The other four did not leave immediately, but gathered around the white wolf and asked the white wolf their questions.

"Teacher, how does the feedback loop work here?"

"Teacher, what exactly will be the quantitative analysis in the next class, what is the quantitative analysis, why can't I understand it?"

I have to say that these foxes belong to the category that is quite studious, and their comprehension is not bad, and the white wolf patiently explained it to them, and they quickly figured it out.

After a while, the other two foxes also left, it was getting late outside, it was already dinner time, Qingyue and Absinthe did not go to the big house to eat for convenience, they always shared dinner with the white wolf, and after dinner it was the white wolf's literacy night school time.

"Isn't it nice for me to be a light bulb here?" the white wolf looked a little embarrassed, the two foxes in front of him were very intimate, and he always felt that he should not be in their world.

"What is a light bulb?" Qingyue asked lightly, leaning on Absinthe's arm, with some curiosity.

The exact meaning of the word is a kind of glass that can emit light when it is electrified, and by extension, it is a single wolf in the background of a loving couple. The white wolf explained in a tone full of resentment.

The two foxes didn't know the exact meaning of the front, but they understood the extension of the back, the faces of the two foxes suddenly became a little feverish, Qingyue hurriedly moved her head away from Absinthe's arm, and looked at the wall on the right with some embarrassment, while Absinthe coughed twice in embarrassment and looked at the wall on the left.

"Isn't it.... Are you so shy...?" This time it was the turn of the white wolf to be surprised, he didn't expect that the foxes who practiced polygamy were not as open as he imagined, and they were actually stimulated by his words like this.
