"Hey, why are you back so soon?" Professor Dongdong came to the window, and the location in front of his tree house was conveniently located under the window. "The idle people who started the gambling game have all scattered. Could it be that someone has hidden it and is it about to make things difficult for you?"

"Professor, I came back because of a question." Dagon took out the "Book of Names", pointed to the handwriting inside and said, "Is this book compiled by Dogolin Tiemo?"

"Yes, it was him. He went crazy in the end. This incident made me feel very sorry. Why, do you know him?"

"I am now living in the 14th pothole, which is the residence before Dogolin Tiemo. He dismantled all the things in the pit, and I found his library card in the corner." Dagon pointed to the number on the nameless book and said, "Professor, this number is a book called "Infinite World Mana". Dogolin borrowed it over and over again and returned it, as if he was particularly nostalgic for it."

"Is that true? Have you brought his library card?"

Dagon has always put Dogolin's book loan proof Ainshi with his own book loan certificate, and he thought that he might be able to get away with the book loan certificate with higher authority. He took out Ainshi and handed it to Professor Dongdong, who carefully checked the records of previous years.

"Well, your opinion is good. Dogolin's behavior is indeed very abnormal, and it may be related to this book." Professor Dongdong said, twisting his beard and said, "You want to find out how crazy Dogolin is?"

Dagon shook his head and said, "I don't know Dogolin and his family, no one entrusted it, and I'm not good at investigating such things, so I didn't want to investigate this. I just happened to find out the connection. Then Dogolin is my fellow tribe and has a talent in spells. I looked at his book, so I wanted to ask a few questions."

"Okay, you're still giving me a face and knowing what to say and what not to say. But I'll say it clearly: I didn't let him read that book, I won't frame my own students, you won't and shouldn't be the next Dogolin, first of all, I disagree. And for me, although it seems crazy and "Infinite World Mana", you may also have a reverse relationship. If it's mental abnormality first, because of this abnormality, he made the move to borrow "Infinite World Mana" repeatedly?"

Dagon nodded in shame and said, "Hehe...Professor. You are right, there is indeed that possibility."

"Well, if you know the embarrassment, there is still a way to save yourself. Most of the people in the Jiangu tribe would rather be stubborn than admit their mistakes. It would be fine if they didn't admit their words, but they were most afraid of not admitting their hearts, and even if they knew they were wrong, they would go on the wrong path - you are not allowed to do that." Professor Dongdong finished speaking, sighed and said, "Dogolin is very talented in spells and works very hard. I feel relieved to let him learn and develop by himself, for fear that he might inadvertently hinder his active thinking and have adverse effects on his development. I'm a little too letting him go, so there is my fault in his crazy thing."

"professor……"

"No need to say anything, it's wrong." Professor Dongdong shook his head and said, "He spent a lot of time on his own, especially in the later stages, and he basically didn't come to class anymore. I thought he could pass the exam anyway, so he didn't care much about this. Later, I heard that he was crazy and I went to see him, but he was completely incoherent at that time and could no longer recognize me."

"Oh, what a pity. I heard from other students that Daogolinn could become a very rare spell master in the Jiangu clan."

"There is indeed that possibility. If you work hard enough, it might be possible. In fact, I think the Jiangu people do not have innate disadvantages in spells. Rune magic is also a good system, and they are not inferior to divine arts, spells, magic arrays and alchemy. Dagon, you have to work hard!"

"Yeah." Dagon nodded vigorously, but he was still a little worried. "Professor, is there really no problem with this book "Endless World Mana"?"

"The stubbornness of the Jiangu clan has appeared again. The book is full of problems and has no reference value." Professor Dongdong explained with a smile: "I have read that book, and you see, I'm not crazy either. The book put forward an amazing idea, trying to make the magic cycle generate infinite mana. In connection with it, it put forward many new ideas in calculation, craftsmanship and formation, but its foundation is wrong. In the end, the person who wrote that book already thought that his theory was wrong, but he refused to admit it. He was particularly stubborn in the book and bewitched others to continue calculating."

"The illusionists pay great attention to details. When I saw that book, it was all wrong. Well... If you say this today, the author of the book might be a little crazy, otherwise he shouldn't have had so many mistakes. Dogolin may have been sick by that book. I should write a letter to the Academic Affairs Office and ask them to investigate."

"Maybe it should." Dagon nodded, he stood up and said, "Professor, I'm sorry to have taken up your time. I have nothing else to do. Let's go to basic learning and make up for the lessons as soon as possible."

"Go!" Professor Dongdong waved his hand and asked the gas servant to come and deliver Dagong away.

After Dagon left, Professor Dongdong sat on the chair, holding his head with his fingers against his temples, frowned, and fell into long and deep thoughts. At this time, a vivid figure of Jiangu tribe appeared in front of him. He was a young man studying at a desk, with a wide and full forehead and focused and lively eyes. He raised his head, smiled at the professor, and asked, "Professor, what are you going to take the exam for me again?"

It was a illusion of Dogolin. He walked out of Professor Dongdong's mind and reappeared in the world with the help of illusions - but unfortunately he would not really come back. After Dogolin's accident, Professor Dongdong tried to repair his brain, but found that there was almost a ball of paste and no sanity was found.

Dogolin was wailing all the time, and the sound of pain lingered around him, deeply piercing the professor's heart and hurting him. The only thing he could do was to create an amulet of illusion, put it on Dogolin's forehead, so that he would always immerse himself in the dream of happiness and joy. If he would be tortured to death by madness, at least he would not suffer.

"Oh, it's really my fault." Professor Dongdong rubbed his temples and came to the desk to write a letter: Dear Academic Affairs Management Office, I discovered during the inspection of past documents that a book called "Infinite World Mana" may have adverse effects on the readers' mental health, and its effects may cause emotional loss, mental loss and brain organ injury. Please send someone to investigate...

The grief cannot be compensated, but it should be prevented. Just as Professor Dongdong was writing a letter to the Academic Affairs Management Office, Dagon came to the library happily and had several more books to borrow. "A proof can improve my borrowing authority." He found the staff in charge of this matter familiarly, and the half-elf from last time, and the annoying eye rolling expression.

From magic class to magic class, Dagon taught two classes for several months, his eye rolling skills did not improve at all.

"You have caused me to lose fifty gold coins." said the half-elf.

Oh, I understand, it turned out that he participated in the bet of "Who can become a professor student in Dongdong" and then bet wrongly. No wonder his face looked so ugly.

"I can win back next time I choose the right one." Dagon said: "I think the feeling of the present is just a prelude to make the future victory sweeter."

"Hey? It's very good." The half-elf rolled her eyes and actually laughed. "What book is this famous quote?"

"The Book of Toby," said Dagon, "Please help me borrow."

"Okay, give it to me. "The Book of Toby", I have to look for it from the library. Is it a reference book?"

"Travel Notes, a very niche book, I also read it by chance."

There is no such book at all, because Toby, a Halfling, has never written it. He often holds card games and gambling activities in the Golden Dog Caravan. Dagon never participates in it, but he often listens to him fooling others. His mouth can make the winner happy and the loser excited. In short, he will participate in it next time.

Compared with Toby, Dagon was not good at "just talk". When he said these words, he was very guilty and nervously stuffed all the books to the half-elf, including the half-elf, because he was in a good mood, and he took all the books that Dagon wanted to borrow and the documents that he had borrowed.

"You don't have to go in. It's just a holiday and there are few staff. If you want to go in, I have to follow you to supervise your authority to prevent you from entering the restricted area. Take these books back and read them."

Dagon nodded and put the certificate in hand first. Only then did he realize that he had taken out two loan certificates. One was his own and the other was from Daogolin Tiemo. When he talked about Daogolin with Professor Dongdong, he turned the loan certificate onto his waist bag and just gave it to the half-elves wrongly.

I don’t know what was wrong with the loan certificate, so the half-elf gave him a copy of "Infinite World Mana". Dagon scratched his head, thinking about whether to return the book. He was still a little curious about the book and wanted to know what happened to Daogolin.

A crazy Jiangu tribe was aware of all Jiangu tribe members in the academy. Dagong hesitated for a few seconds, but decided to leave the book and stuff it into his backpack.

On the way back, Dagon was very nervous and hesitated several times to look back. He always felt that this was not done openly enough, and it was not what he was used to. Although he was not a thief, it could not get rid of the word "sneaking". Until the door of the pit, he was increasingly inclined to return the book, as if the book would cause unknown information when it returned to the pit No. 14.

"Dagon, have you done something bad?"

Dagon was shocked and realized that he had lost his vigilance and did not notice that there was a long-legged elf woman sitting on the pit gate.
