So Ciri is stuck in a life of two busy tasks, electives and labs, no, it should be three, because now there is another college database to add.

Ciri's teaching is still going well, those observers have increased every class, but for some reason they didn't disturb Ciri's lecture, seeing that a group of them were sweating profusely but had the appearance of wanting to speak and stopping, Ciri felt that he would give them a brief explanation when he had time in the future. However, he doesn't have this time now, although the progress of [Numer Profiler Type II] is very smooth, and the workload has gradually decreased, but he has encountered a lot of problems in the study of summoning spell materials.

Many spells involving time and space are incredibly profound, especially the parts that involve time.

What time is, no one can really say clearly, no one can even know the answer, let alone say it clearly.

Although time can neither be heard nor seen, everyone can feel its presence, or rather, we do not feel time itself, but its influence on everything.

Although there are a lot of summoning spells, they are actually different variants of the same summoning spell (the random summoning spell mentioned earlier, because the creatures it summons are relatively weak and does not need the support of time talent, all mages can use it after studying spatial knowledge, so it is classified as a general auxiliary spell. Although the random summoning spell bears the name of a summoning spell, it does not belong to the ranks of regular summoning spells), this summoning spell is to summon a time mirror, sign a contract, and then summon it during battle.

It's just that due to the different objects of the contract, the summoning spells with different names developed by different mages have not changed in essence. Nor were any humans who developed this spell, and even the goblins, who were unique in their ability to conduct experimental research, only developed this spell on the basis of others, and they were not able to create a truly new summoning spell.

Why have so many geniuses failed in this aspect, and who is the real inventor of summoning?

Quite simply, there is a connection between these two issues. So many geniuses have been defeated on the road of researching new summoning techniques, because this kind of spell requires extremely strong space-time talents, and the guy who invented the summoning technique is naturally the most powerful guy in the Colin plane, at least once belonged to the dragon clan of the Colin plane.

That's right, summoning is indeed one of the oldest spells in the world, even dating back to the distant time of the dragons. It's just that it was discovered by humans much later, so summoning mages is not a long-established profession now.

Legend has it that a dragon with an unusually strong talent for time and space sensed the deepest secret of the Colin plane--- time, and he used his knowledge of time to create many extremely powerful and strange spells, but these spells could only be used by him with a strong talent for time. Eventually, he created a spell that could be used by any other intelligent creature with a gift for space, and while it wasn't as powerful as the spell he had first created, it was finally able to be used by sapient beings other than him. This spell has been handed down to the present, and with only one spell, it has formed a whole class of summoning, the full name is called space-time summoning.

While any mage with a space-time talent can learn this summoning spell, it must be learned in order to use it. It's easy to say that the learning of space-time summoning is as easy as it is difficult to say. Because you only need to learn one summoning spell to be able to bypass other summoning spells, but this summoning spell is more difficult to learn than all spells in other mage schools.

Take, for example, the runes needed to summon the special circle used in the Time Mirror. This particular rune is called a time rune, but it doesn't actually belong to the category of runes, but is just named after the time rune. Every thing known as a rune of time is actually a special kind of law. Unlike other magical runes, each of which is a special image that is constantly changing.

To master a time rune is to master the characteristics and laws of its appearance, and because the changes of time runes are disorderly and non-repetitive, the requirements for mastering it are infinitely higher. All the carved time runes are also naturally in a state of flux, which makes this special rune more difficult to learn. Only those who have a certain degree of natural ability in time and space can complete this learning process under the guidance of other people or materials. In contrast, this particular method of arrangement is also a special rule, unlike other magic circles, which are fixed in a fixed position.

In addition to the difficulty of learning the magic circle, the summoning mage must also establish his own clear view of time, otherwise even if he completes the depiction of the magic circle, he will not be able to feel the existence of the time mirror image at all, let alone summon it.

What exactly time is a question that has been highly debated since time immemorial.

Some people think that there is no such thing as time at all, it is just a parameter that people use to describe the process of material movement or the process of events, it is just a concept, and it is the change of things that gives meaning to time itself.

Some people think that time is a real thing, and it can control the change of things in some magical way. Time itself is the master of existence beyond all things, it can control everything in the world, and it itself is not affected by any external factors, at least no one or anything can do this. However, it is said that the space-time dragon that originally created the summoning spell can affect time through spells, but no one knows the truth of this now.

The space-time dragon left the Colin plane shortly after creating the spell, and no one knew where he went, and he never returned. In fact, if it weren't for the departure of the space-time dragon, the elves would not dare to start a war against the dragons. Because in the legend, the ability of that space-time dragon has reached an incredible level than the strength of the entire dragon race, and if he is still in the Colin plane, the elves will not even have the courage to resist.

Today's summoners generally regard the latter idea as the true form of the existence of time, believing that time does exist and can control all things. At the same time, they divide time into many different categories. The two main categories are ultimate time and ordinary time
