Although he promised to help the lich, he couldn't just leave. At the very least, there must be some preparation, especially for mathematical tools.

The previous time, in order to calculate the outline of the space warp and related data, I had to use some stupid methods to calculate it improvised, and the result was particularly brain-burning. This is still a simple calculation, no need to be distracted in other aspects, in order to get the calculation results safely and securely.

If you want to fight while fighting, or other things, this level of computing power occupation is likely to be a small life. Therefore, Lin made special preparations for the mathematical tools that may be used on this trip.

Of course, it is impossible to be completely prepared. Because we are going to a strange place, how can we be prepared for everything we can when we don't know what will happen or what problems we will encounter. Besides, if you are entangled in this point, you will not even be able to set off. So it's enough to prepare for seven or eight points, and the rest is still up to the moment.

In addition to all kinds of preparations, things at home are well arranged, anyway, from the beginning it was those apprentices in charge, and it was not a problem whether someone was there or not. On the side of the academy, Lin pondered another question and found Fen, who was also a teacher in the academy.

The lich asked, "Is there anything going on at the Academy?" ”

"I'm thinking about whether I should ask someone else to substitute for the courses at the academy. What do you think? ”

It has been two or three years since the Math course at Kabambai College was launched. In the original plan, I wanted to teach everything I knew about mathematics in five to seven years, regardless of whether the person who learned it really understood it or not.

But plans don't always keep up with changes. The practical mages have no interest in continuing their studies in the field of pure mathematics after the mathematical methods they have learned are enough to transform and revise the spell model. Only a few young people who have not been deeply involved in magic have shown an interest in pure mathematics. But it's just an interest, but it's not a good enough talent.

Although Lin continued to teach them advanced mathematics, he did so slowly. No one has ever thought about improving this situation. After all, if mathematics continues to go down, the less dry goods you will have in your stomach, and it is not impossible to be asked.

Not long ago, the direction of mathematics teaching was similar to that of the life course taught by Fin, and it became a group research project, and the content of the research content was of course mathematical problems at the practical application level. The most approved group project is, of course, the optimization of spell models for apprentice-level magic from one to three rings.

The formal course time is the time for everyone to brainstorm and find solutions when the existing mathematical tools are unable to solve the problem.

In addition to the group-based project research, the second round of teaching was also carried out in the mathematics class. That is, to re-teach the old, publicly available mathematics. The target is, of course, a group of new students, after all, the class of the previous grade is full of more than 100 people; Compared to the number of magicians who want to learn mathematics, it is not an exaggeration to say that it is a drop in the bucket.

In addition to Lin's second math course, many of the old students of the first math course also stayed at Kabanbai Academy, and were invited by the academy's elder magician Kabanbai to open the same math course. In the hope that more people will have the opportunity to learn mathematics systematically at the same time.

The old head of the academy did this, of course, with Lin's consent. On the road of promoting mathematics, the more people who are recruited to preach, the more advantageous it is to fight alone.

But the after-effect of this is that someone's importance has diminished. Now, in addition to serving as an advisor in the old cadet class that no one will ask about, it is to bring a new class and start teaching the basics of mathematics again.

However, the diminished importance is not without its benefits. That is, Lin can take a long vacation, and he will not be eaten alive by those lawmakers who are thirsty for knowledge. And now there are people who can substitute for the teacher, anyway, only basic and intermediate math are taught.

If it weren't for the fact that someone didn't want to feed the aristocracy completely, he would have relied on the monthly allowance of the Marquis de Balan, and the salary of a consultant in the automobile manufacturing center. Keeping a teaching position at Kabanbai College is really just someone who avoids going back to his home where he has nothing to do all day.

Before today, someone could go back and forth in an instant, no matter how far away they were, with the convenience of flashing. Therefore, most of the arrangements for long-distance trips are to deal with some personal matters in the morning, and go to the college in the afternoon to teach mathematics. But the downside of this is that you usually have to finish your morning work halfway through; Then after teaching the math class in the afternoon, the rest of the work continues tomorrow.

Although the time seems to be fully utilized, in fact, the effort spent on finishing and starting again the next day is not known how much more progress can be made if the work can be carried out consistently. So Lin pondered whether to take a long vacation this time, take a good job, and concentrate on getting Fen's affairs right, so he had such doubts.

Instead of directly agreeing with someone's idea, Fen asked with a slight surprise, "What are your considerations?" ”

Lin replied, "I'm quite new to the elemental world, and I can't guarantee that anything will happen. According to you, you should be similar to me. Therefore, in the process of exploration, there is no need to worry about returning to the college to teach at a certain time, which should be conducive to our exploration. And if we want to stay among elemental beings and negotiate with them, how can we explain or conceal that we disappear at certain times of the day? At least for a while, as long as I am out and about, not only do I have to take time to go back to the academy, but also hide my whereabouts at this time, which is a very troublesome thing. That's why I thought about whether to take a leave of absence and suspend the teaching at the college. Anyway, now there are other people who can substitute for the class, and I don't need to be there every day. ”

"Indeed, if you are stuck in the middle for a time, it is really not very convenient to act." After thinking for a moment, Fen said, "It seems that my life course has also been suspended for a while. Now it's all group research, and I don't have to check it every day. ”

Although she didn't answer positively, since Fen had the same intention, it could be regarded as a side explanation that she agreed with someone's approach. After discussing for a while, the two found the old head of the academy, the great magician Kabanbai, together the next day, to explain the matter of asking for leave.

The old man didn't have any embarrassment, and agreed in one bite. Including the substitute candidates recommended by the two of them, they also have no opinions.

Speaking of which, in the Lost Land, the magician occasionally leaves his base. or engage in adventurous activities so that you don't stay away from actual combat for so long that your hands are raw; Or it is normal to look for magic materials that you need, but are relatively special and rare. This is just like the change in appearance, which is not a big deal for the magicians of the Lost Land.

Otherwise, someone's appearance has changed dramatically twice since he came to the holy city of Estali. First, he was baptized by the eight powers and became skinny. Then there is the demonic transformation, and he regains his youth. If it were placed on Earth, some people would have wondered if they had been impostored. But in the Lost Land, this will not arouse any interest and attention from the masters at all.

Should I say that the magicians in the Lost Land are very big and have turned into them, or should I say that the people here have long been surprised?
