My understanding is incredible, I built a floating city in Hogwarts

In order to avoid the front lines heavily guarded by demons, Levin set out from the Vanguard Camp and embarked on a tortuous detour. He spread his wings and flew for three consecutive days and nights without stopping until he reached the border between the northern territory of Zandalar and Nazmir, then adjusted his direction and resolutely advanced northward.

Although the journey was full of hardships, it also allowed him to successfully bypass the iron wall-like defense line set up by the Burning Legion in the east of Sin Azshari.

Compared to the main battlefield in the east, the south and west of Sin Azshari seemed relatively calm. Although there were garrisons, they were mainly moon guards deployed by the upper elves themselves, and the traces of demons were almost impossible to find.

Most of these moon guards gathered around the city gate. Levin flew all the way until he arrived at the outskirts of Sin Azshari, and he never encountered any form of obstruction or questioning.

Then, he landed steadily on the branch of a towering ancient tree, maintaining the agile posture of a flying eagle. When he looked over the sky of the city with his extremely sharp eagle eyes, he found a thorny problem.

I saw a faint purple light curtain, covering the entire city of Zin Aishali like a veil. This is obviously a defensive barrier, and its existence makes Levin's next move extremely difficult.

"This is a bit troublesome." Levin thought to himself, frowning slightly, "How can I hide from Zin Aishalin's defensive barrier and enter the city?"

In the Dark Night Empire where the arcane civilization is prosperous, the ancient and primitive way of guarding the city gate with manpower and distinguishing the identity of the entrants with the naked eye has long been eliminated by the times.

Instead, the upper elves led by Xavius ​​carefully constructed an extremely grand magic barrier with the help of the endless energy of the Well of Eternity.

According to the rules of the world of Dungeons and Dragons that Levin had heard of, the real scientific name of this barrier is [Mystery Lock].

[Mystery Lock] itself has a simple consciousness, and is given the task of protecting cities or holy places by its creator - their lifespan can be hundreds or even thousands of years.

The literal meaning of barrier is a protective shield, but the function of [Mystery Lock] is more than that. The design purpose of [Mystery Lock] includes but is not limited to protecting certain creatures within its range, expelling certain creatures, detecting creatures within the range, etc. Its operating principle is to infuse and maintain a series of spells in a huge field. In addition, each [Mystery Lock] also has some unique abilities that cannot be directly described by spells.

And the function of Isaline's [Mystery Lock] includes detecting every creature that attempts to enter the city. Whenever an unqualified person rashly approaches the edge of the barrier, its built-in early warning mechanism will be instantly activated, and the piercing alarm will echo over the entire city, announcing the arrival of the invader.

It is worth mentioning that the detection capability of this magic system is not limited to humans. It can even see through the disguise of druids in animal form, thus completely eliminating the possibility of them trying to fish in troubled waters and sneak into the city.

Before setting out, Levin had learned about these crucial intelligence from Malfurion and Jarod. Their detailed description gave him a deeper understanding of the city's defense system and enabled him to formulate countermeasures in advance.

However, although the existence of the magic barrier made the city's defense seem impeccable, a certain number of elite soldiers were still stationed at the city gate.

After all, although the barrier is powerful and has simple intelligence, it is ultimately a dead object and lacks the flexible adaptability unique to humans. The existence of these soldiers is to deal with possible emergencies and ensure the absolute safety of the entire city.

At this moment, in front of the gate of Isalin, a bleak and desolate scene is presented.

Years of war and turmoil have made this once prosperous city deserted, and people have avoided it and are unwilling to easily set foot in it.

Occasionally, a few merchants come, and they hurriedly shuttle between the city gates, with nervous and solemn expressions. Levin noticed that when they stepped into the range of the barrier, a subtle white light would instantly pass through their bodies, as if the barrier had verified their identities in some mysterious way.

Levin observed all this quietly, his mind racing.

Suddenly, an idea flashed through his mind, and a meaningful smile appeared on the corner of his mouth.

He thought of a person, an "insider" in the city of Isaline.

This insider was none other than the other of the two victims he had ntr, Malfurion's younger brother, Illidan.

After Levin left the barracks and looked for reinforcements, Illidan soon disappeared mysteriously, and was mistakenly believed to be dead by everyone. However, Levin knew that Illidan did not disappear, but chose another path.

In the previous protracted war, Illidan deeply realized one thing, that is, the mage has its limits, so he made an amazing decision-he will not be a mage!

In pursuit of unparalleled power, Illidan made an amazing choice - he decided to "throw himself" into the arms of the Burning Legion.

For this, he did not hesitate to offer his eyes in exchange for the power of the fel energy from the dark titan Sargeras. In this way, he became the world's first demon hunter, a lone warrior walking on the edge of darkness and light.

However, from the name of "Demon Hunter", Levin could see Illidan's true thoughts. His betrayal was not out of sincere surrender, but to go deep behind the enemy, understand all the secrets of the Burning Legion, and find a way to completely destroy this evil force.

In other words, he is an undercover, a traitor lurking in the heart of the enemy.

After all, as a licker, Illidan always cares about his goddess Tyrande in his heart. As long as Tyrande is still resisting and fighting against Queen Azshara, Illidan will never really betray his fellow night elves.

WhenOf course, the Burning Legion is not so easy to fool. They will not easily believe Illidan's surrender, let alone let him rise to the top and directly enter the core layer.

Even if he is favored by Sargeras himself, Illidan must prove his loyalty and value by completing a series of arduous "field missions" as a token of his surrender to the Burning Legion.

And this is exactly the opportunity Levin wants to take advantage of.

He knows Illidan's situation and thoughts very well, and also understands the unique position of this demon hunter in the Burning Legion, which is exactly what he can take advantage of.

In the lonely and deserted night, Levin quietly launched the prophecy spell - [Higher Exploration].

At this moment, he no longer needs to hide the fact that he can do magic, and all his mind is focused on finding the location of that important person.

[Higher Exploration] is not a simple spell. To be accurate enough, it requires the caster to not only have excellent casting skills, but also have a deep understanding of the detection target.

The more the caster knows about the target, the better the effect. At the same time, the closer the relationship between the caster and the target, the stronger the effect.

In order to further enhance the effect of the spell, Levin also specially prepared items that Illidan had used. These items still have the breath of Illidan and can be used as important props for casting spells.

In the complicated ceremony, Levin felt the power of the spell gradually condensing. Finally, from a perspective that only he could see, an invisible beam of light penetrated through the layers of fog and shot into the distance, accurately locking Illidan's position.

In the next two days, Levin did not act rashly. He patiently monitored Illidan's every move and gradually figured out his activity patterns.

He found that Illidan would always choose to set out from a certain gate of Ishalin at a fixed time to perform his "field mission".

So, Levin decided to take action. He spread his wings and flew high, rushing and hurrying, crossing the vast 007 territory of Ishalin and heading straight for the south gate. There, it was the place where Illidan had been frequenting recently.

Ishalin was so big that Illidan couldn't run in every direction of east, south, west and north when he was on a field trip. For convenience, he would always choose a fixed direction.

Soon, Levin arrived at his destination.

The latest detection showed that Illidan had another "field mission" and was on his way back to Ishalin.

Levin immediately decided to stay in a forest at the city gate and block Illidan on the road he had to take.

In order to ensure that his actions were foolproof, he cast the two spells [Control Animals] and [Control Plants] in succession, and at the same time supplemented by the ability of [Asking about Nature], instantly mobilized the animals and plants within a few miles around, making them his eyes and spies to detect the dynamics around him.

He himself lightly jumped onto the branch of an ancient tree a little further away from the city gate, and quietly looked down at the movements below like an eagle.

Druid spells are indeed effective in reconnaissance.With the unique advantage of nature, these spells can use the power of nature to let Levin know the surrounding environment.

However, he also knew in his heart that although these spells were powerful, they could not be compared with the alchemical products made by magic, such as the Secret Eye, in terms of accuracy.

Although animals and plants can provide him with certain information, their intelligence is limited after all, and they are not competent for overly complex reconnaissance tasks. In contrast, the Secret Eye is like a drone with a high-definition camera, which can transmit clear images in real time and provide more intuitive and comprehensive intelligence.

It's a pity. The Azeroth he is in now is far away from the world of Harry Potter. He can't summon the magic pet Aiwu or the artificial maid in that world to assist him.

If he were in that world, he might be able to deal with the situation more easily. But even so, he still has to make full use of the resources at hand.
