The Witcher: Son of the Planes.

After seeing his daughter Orianna off, Colin first stopped by the base in Uxu City to check on the operation of the law enforcement team. After a brief exchange with Vincent about the latest situation, Colin went to the national library of the former Principality of Denton - the Selnarin National Library.

What surprised Colin was that the librarian was actually his old acquaintance, Magician Brian. More than a hundred years had passed, and Colin had been promoted to level two. No matter how bad others were, they would have been promoted and were already top-level magicians.

All the prominent figures in the Victoria Islands have seen Colin's portrait, as he is a "legendary" figure from the former Duchy of Denton. Moreover, Brian had seen Colin frequently for a period of time before.

Brian used to be stronger than Colin, but he didn't think much of it. But now that Colin came over, Brian suddenly felt the gap, the gap between level two and level one. He respectfully applied for a library card for Colin.

After all, whether it is Colin's current identity as an elder of the Magician Council or his recognized status as a duke of the three principalities of the Victoria Islands, it is not something Brian can neglect.

Entering the Selnarin Library again, Colin felt as if he was in another world. He always felt that Selnarin was very large and had a large collection of books. But after visiting the libraries of the three duchies, the contrast became obvious. Although the Caroline family attached great importance to the reserve of knowledge within the former duchy, its foundation was far inferior to that of the three duchies.

But since Colin is here, he still has to check it out carefully. There are still many knowledge points in it that Colin has not seen before. Although the inheritance of a magician is different from that of a wizard, they both apply the rules and have great reference value.

Wizard Vincent was a little surprised that Captain Colin had been staying in the library reading books recently. At first, he didn't care, thinking that Colin wanted to read a lot of books and would leave after a few days. As a result, Colin stayed there for more than a month. For this reason, Vincent specially sent a secret information to Griman College.

Mario appreciated Colin's eagerness to learn. He received Vincent's information but didn't say much. Although he was a little annoyed by Vincent's fuss about the information, it was arranged like this when the academy set up the security affairs division, so he naturally couldn't say anything.

In his impression, Colin has always had his own ideas. When he was in college, he always aimed to be promoted to the next level, and finally achieved this goal. Later, after leaving the college, he joined his mentor Lina and experienced the plane wars many times. Although his strength is not top-notch, he is not a novice in the academy. The only thing he lacks is the accumulation of knowledge. Now he can calm down and study, which shows that Colin is still aware of his shortcomings.

As for the wizard Vincent, if he does not focus on improving his strength and accumulating knowledge, he will fall behind sooner or later. Level two will be a hurdle he will never be able to overcome in his lifetime. However, this is his own choice, and Mario will not care about him.

Colin's one month of study in the Selnarin Library was like returning to the short semester in college in his previous life. There was no need to consider any supernatural powers, and there was no interference from senior and junior students. Although it was boring, he gained a lot.

As for the origin of the Victoria Islands (small world), he only took a cursory look. Under the current circumstances, he has not yet discovered the plane coordinates of the magical world. Moreover, even if he did, what good would it do? If he wanted to have "friendly" communication, he must have equal strength to guarantee it.

Colin spent more of his time understanding some basic spells and having a superficial understanding of the rules. Magicians, like wizards, also attach great importance to knowledge and are pursuing the true laws behind things, but there are differences in the process of mobilizing basic elements to cast spells.

Wizards of other categories are naturally different from magicians. As for elemental wizards, they are more likely to directly and "roughly" mobilize and use the elemental particles that exist in the material world, and use them directly according to certain rules to cast witchcraft.

Magicians use mental power to communicate with the elemental particles of the material world and use certain rules and specific arrangements of elements to release spells.

One is to use it directly through one's own mental power, which is a model of leveraging the rules by oneself. The other is to communicate through one's own mental power, using one's own understanding of the rules to borrow "other people's" things to use.

There is a common point here, which is the understanding and use of rules. Although there are not many book categories in the Selnarin Library, the simple introduction makes Colin understand that the proficient mastery and application of rules is the direction that Colin needs to work hard in the future. A wizard or magician who can be promoted to level four should be someone who has mastered certain rules. Only by mastering a certain rule can he be called a "god".

While reading in the library, Colin also communicated with Brian about some magician knowledge and spellcasting principles.

Although he had been promoted to level two, Colin was still not as good as Brian in understanding this knowledge. To express his gratitude, Colin gave him three drops of the Fountain of Life.

Seeing that the Selnarin Library could no longer be of any help to him, Colin finally left reluctantly. His next stop would be the national libraries of the three duchies, which would surely bring Colin something.

Walking out of the Sernarin National Library and looking at the Fina Garden across the street, Colin found that this once famous den of money-spending was still as lively as ever. However, Colin was no longer a young man in his twenties. He had seen everything and naturally would not go in to look for anything new and exciting.

Colin planned to revisit old places in order of distance, first going to the library of the Principality of Huiyao, then the Principality of Haoyue, and finally the Principality of Zhanlan.

Colin did not inform his relatives on the Cavendish side when he came, so naturally he would not do so when he left. Vincent only learned of Colin's departure two days after he left.

In terms of the control of the personnel stationed in the Uxu City Law Enforcement Team, although Vincent is the specific person in charge and is from the Griman Islands, and of course there are people who take the initiative to come over, more substitutes and non-staff personnel still recognize Colin as the captain.

After all, the county magistrate is not as good as the current manager. Colin is the captain and a second-level wizard. Vincent is a wizard sent by Griman College and is only a first-level wizard. When it comes to arm wrestling, everyone naturally knows how to choose.

Since he didn't dare to actively monitor Colin, Vincent's channels for information naturally became much fewer. He got the news when someone inadvertently said that Captain Colin had not been seen in the library for two days. Only then did Vincent get the news.

Vincent did not get a response from Mario in his last report. This time, Vincent learned to be "smart" and finally did not say much in the secret report. Instead, he reported the situation of the law enforcement team in the Victoria Islands normally.
