Rebirth in the Soul Street: Becoming a Demon King in Another World

"First, determine how you evaluate magic. All strange phenomena caused by magic are called magic..."

"...Magic has four different names according to different characteristics: common magic, racial magic, forbidden magic, and source magic. They have different magic names, but they are not independent of each other. For example, some magic may be both common magic and source magic, or both forbidden magic and source magic..."

"...consider your magic power as energy, and the magic circle is the key to your application of magic power. The magic circle can be divided into source magic circle and derived magic circle..."

"..."

Cao Yanling did not teach Weber magic directly, but only told him the common sense of magic in the magical world. However, just this common sense of magic was more important to Weber than all the treasures in the world, and it benefited Weber a lot.

The magic users in the human world, except for some ancient or special magic circles, have not conducted in-depth research on magic circles. They mostly just release magic based on magic principles with the help of magic circuits.

The magic circle is to integrate and refine the magic principles to make it more stable, simple and more efficient. In fact, they are not without the ability to construct magic circles through magic principles, but there are three reasons why they have not formed a magic circle system.

First of all, this is a rigid ideology. They think that since magic can be released through magical principles, why should they use magic circles?

Secondly, it is the denial of magic circles. Perhaps because the development history of magic in the human world is not long, their understanding of magic is not deep enough, and the magic circles they construct have defects. Using those defective magic circles is not as convenient as using magic directly according to magic principles, so they deny magic circles.

Finally, it is the advantage of the magic circuits of the Demon Veins that allows them to use magic more easily through magical principles.

After understanding the magic circle system and seeing a magic circle with similar hypnotic power, Weber has completely agreed with the magic circle system and taken a step forward.

Waver Velvet, as the monarch of the modern magic department of the Clock Tower in another time and space, has demonstrated his talent even in this chaotic time and space.

In Weber's hand, a magic circle that condensed almost all of his knowledge emerged. The magic circle shone with a faint light, absorbing Weber's magic power like a greedy buffalo.

Cao Yanling was surprised again that he had actually deduced the magic circle. Although there were still some flaws, it was enough to prove his talent.

Different from the previous contact learning, this is a deduction based on the principles of magic, which even real magicians in the magic world cannot do.

As for Weber, his magic power only reaches the level of a mage.

In the magic world, simply possessing powerful magic is not recognized by others. Those who do so will be labeled as pseudo-mages. Only those who master the corresponding magic and knowledge are true magicians.

Although this magic vein user named Weber did not master powerful magic, he already possessed knowledge beyond his magic level.

Due to the existence of defects, the magic circle was devouring Weber's magic power, and he had no choice but to take back the magic circle.

At the same time, a magic circle very similar to the one in Weber's hand appeared in Cao Yanling's hand, but with a few more patterns.

The magic circle has the uniqueness of the source of magic.

Whenever a new and perfect magic circle appears, this magic circle will be captured by the source of magic, forming a unique magic circle. Subsequent magicians will not be able to create other magic circles with the same effect, and can only deduce this unique magic circle.

But there is also a rumor that as long as the magic circle you create can completely crush the only magic circle, then this magic circle can become the new only one.

However, Cao Yanling had tried it before, and it was almost impossible to accomplish. Because the only magic arrays determined by the source of magic were perfect magic arrays, and the efficiency of using magic power was extremely high, and it was almost impossible to surpass it, so he could only start with the magic effect, and that would only allow him to create other unique magic arrays or deduce other unique magic arrays.

At this time, the magic circle constructed by Cao Yanling is the perfect magic circle deduced by Weber.

——Aura Magic·Eye of Identification

When Waver saw the magic circle, his face, which had been pale due to the massive loss of magic power, instantly turned red with excitement.

At the same time, a magic circle appeared again in Cao Yanling's other hand.

——Puppet Magic·Memory Modification

"Okay, you go out first! I'll call you if I need anything."

After Weber had completely memorized the construction methods of the two magic arrays, Cao Yanling began to drive people away.

"Also, teach me the magic circle of the contract magic you mentioned earlier!"

Weber had been immersed in the study of magic and seemed to have completely forgotten the difference in status between them. He thought that he was just a research subject.

What a huge contrast!

Cao Yanling thought, is this really the boy who fainted from fear? How dare he go even further?

However, before driving Weber away, he still taught Weber the magic circle of contract magic.

Shortly after Weber left, Cao Yanling also went out to wander around, constantly releasing shadow servants to search for a powerful source of magic power.

A quiet place shrouded in darkness, a villa of the Einzbern family in Fuyuki City.

Emiya Kiritsugu and Irisviel responded to the clan leader's call and rushed here.

Ahad, the old man who is the lord of Winter Castle and the head of the Einzbern clan, was waiting for Kiritsugu and Irisviel in front of the fireplace in the living room of the villa.

"Clan leader, why are you here?" Kiritsugu asked in confusion.

In the past, the clan leader's summons were always sent to Einzber Castle, a dark and magnificent ancient city sealed by ice.

Ahad did not answer, but five people walked out from behind him. The powerful aura instantly put Kiritsugu into combat mode.

“Don’t be nervous, Kiritsugu!” Ahad’s words made Kiritsugu relax a little, but he still kept his body in front of Irisviel.

"They are visitors to the Magic Palace, honorable Holy Seers."

The patriarch of the Einzbern clan, an old man who had lived for almost two centuries by continuously extending his life. He was not as ignorant as the modern magicians in the Clock Tower. He had witnessed the power of the Holy See with his own eyes and had great awe and yearning for the Holy See.

He once thought about entering the Magic Palace, but his family's mission made him waste his youth. When he looked back, the Magic Palace had been abandoned and his body had become old.

"The Holy Seer of the Magic Temple, they brought the holy relics we need."

It was an honor for him to be granted the Holy Relic and to be found by the returning Holy Lord. Moreover, the Magic Palace had invited him. Now that the eight Holy Thrones of Magic Lords were vacant, the Magic Palace needed new blood. He accepted without hesitation, making up for his regrets of nearly two centuries.

The Magic Hall has 24 Holy Seats, including the Two King Seats, 11 Magic Lord Seats and 11 Magic Knight Seats. Although it is unknown why there are only three lords and four knights left, this force can still easily destroy the ignorant people in the Clock Tower.

Moreover, the Magic Hall records countless magics, which may allow him to go further.
