Dawn of the Grey Tower

Originally, Cheese didn't think that the gray tower had a similar energy core, because the spells in the gray tower were higher and more restrained than the city of magic, which meant that this tower could use less magic power to operate the magic in the tower. All kinds of inconceivables also mean that it requires almost no additional energy supply.

But if the gray tower actually hides some functions and systems that he hadn't expected before, then the situation will be different. In the case of the greenhouse in front of us, it needs a stable temperature, in other words, heat. This is an overly extravagant resource on the ice sheet. Even the forts and shelters built by the gray robes themselves are unable to build a system that can provide constant heating.

The difficulty is on the one hand, and on the other hand, there is no material on the endless ice field that can be used as a basis for heating. Unless, the gas of the gray tower sinks, no geological activity occurs.

Then the energy source of this greenhouse is likely to be similar to the City of Laws, using sunlight or wind to operate. It's simple to say, even for mages, if they want to use the invisible energy of light and wind on a large scale, they need to lay complicated equipment to ensure the conversion efficiency and consumption.

At the same time, it is better to preserve this energy in a flexible intermediate state that can be accessed at any time, rather than like a windmill, which cannot be ground without wind. After converting this set of requirements, it is impossible to say that there is no energy furnace or energy core in the gray tower. But in what form and where does the core exist?

"There are also returning things here. Somewhat abnormal." Curse Crow held a few fresh fruits in his hand and said with a strange expression. These red fruits are delicate and lustrous, with some dew hanging on them.

But the strange thing is that in the place where the Cursed Crow found them, the main body of the plant that should have bred them had already died of being plundered by other plants in the cruel competition in the greenhouse, withered and rotted, leaving only barely recognizable remains. The rotting remains do not produce such healthy fruits, and they must have been produced by Afsan while tending the greenhouse and returned only recently.

"Even the fruit will return? The teacher will not do such a thing even if he is casual." The collection of books in the library has a certain value. The medicines in the medical room are of high value.

Fruit in the greenhouse? Both the cheese and the cursed crow couldn't figure out why they were cast the same spell as the above two. If the first gray robe purposely hid certain things in the tower, then there should be no place for these fruits in his purpose.

Unless the regression phenomenon in the tower is not completely controlled, the right to choose the hidden things is not restricted by the caster.

"If so many things in the tower can be split into different realms, the spells used must be difficult to be perfect. The aftermath of magic is likely to randomly generate victims within a certain range."

Cheese tried to construct a similar spell in his mind, but concluded that it could not be simulated. It is one thing to know the principles, but it is another thing to be able to penetrate multiple realms and accurately split the different characteristics of a thing into corresponding parts. Today's cheese lacks both an understanding of multiple realms and the means to conceptually separate things. Therefore, what he said can only be guesswork after all.

"Maybe so. But there is another thing that confuses me." Cursed Crow said and took a bite of the fruit, which of course would not bring danger.

Although this fruit has theoretically matured for too long, all its parts have been disassembled, like arrows flying in the air. The shot arrows seem to be moving for granted in the eyes of others, but if the time is sliced, from the extremely slow time periods, the arrows in each period are still in the air.

Of course, this discussion is not really to prove that the arrow does not move in the air, but to illustrate the divisibility of time and the non-absolute relative relationship between stillness and movement. The fruit in Cursed Crow's hand is another version of this discussion, but through the intervention of magic, it has really achieved a certain sense of immobility. The pulp chewed in Cursed Crow's mouth is no different from that before it was split.

"If there are more than dead things returning, right? It's reasonable to think so. If the teacher used this spell not to hide, but to exile some enemies who entered the gray tower, what we see now is just the aftermath of the spell. As for the effect..."

Cheese followed the idea of ​​the cursed crow and thought that splitting magic could affect living creatures, and then considered under what circumstances the first gray robe would use it. Enemy invasion was the most possible option he could think of, because he couldn't or didn't want to defeat the invaders head-on, the first gray robe chose to banish them to the future at that time.

"Is there anything worth doing for him? If he can dismantle his opponents into fine slags that can't even affect time, why doesn't he just destroy them?" Curse Crow weighed the fruit in his hand , raising doubts about the cheese conjecture.

Indeed, with the means of the first gray robe, he has placed his opponents in a position where he can handle them at will, why not directly eliminate them, or simply banish those intruders to some other place, but instead use them completely The undamaged state remains in the gray tower? Is there any benefit in doing this?

"Exam. Just like what he did to us before, what if this is an exam? He uses various arrangements to ensure that we will gather at the Gray Tower at this time, and then release opponents from the past to assess adulthood Whether we are qualified in the future."

"What is qualified? We are already independent gray robes, he has nothing to teach us, and there are no skills we must master."

The conjurer frowned, feeling a little helpless at cheese's increasingly outrageous thoughts. Ever since they became adults, the first gray robe has indeed never asked them anything.

The cheese didn't go on. In fact, in his heart, there is one thing that is worth the effort of the teachers of the gray robes to test the students, and that is the gray tower.

This mage tower, which is still surprising them today, can only be controlled by the most outstanding spellcasters. An Lina is already a vampire of the true ancestor level, even in the age of mythology, she can gain a place, but she is not far behind the gray robes in the way of magic, and she is even neglected in the study of magic because of her original power.

If not, she would not be unable to leave the stargazing room now, and instead be bound by the gray tower as the controller.

"No matter what the teacher's purpose is, we still have time to continue the investigation. The first step is to find out where the greenhouse gets its energy from."
