The Demon Hunter standing in the main control room of the Well of Eternity looked dazed, he did learn some basic ancient elven language with the half-elves, but this knowledge only allowed him to read the words written on the door plate.

Xu Yichen guessed that there was originally an independent protective magic circle here, but now this room where the floor, ceiling, and walls were covered with magic patterns had almost been destroyed.

A large number of scorched black marks, artificially destroyed magic lines, and maliciously applied magic paint all made it completely lose its original effect.

The core of the Locking Circle had been similarly damaged, an open field the size of a football field, thirteen slender metal pillars supporting the weight of the all-metal room, and dense patterns engraved on the metal surface that made it a headache to look at.

Xu Yichen couldn't tell what kind of metal was under his feet, but he knew the metal that was filled in the grooves of the magic pattern and used to solidify the magic circle - Mithril, the metal known as the best magic material.

This metal hall alone can give people an idea of the power of the elven spellcasters in the era of the Elven Court.

The vast and intricate star-like magic pattern engraving on the ground was almost to the level of miniature carving technology, and the enhanced eyesight of the demon hunter could only barely distinguish the interlocking intricate patterns.

If under normal conditions, the magic pattern hall where the core of the magic circle is located is completely forbidden to mobs, any stampede may cause problems with the operation of the circle, and there is a special cleaning magic to keep it dust-free, because the slightest dust particle may also cause a change in the conductivity of magic energy in the circle locally, which will eventually evolve into high temperature and fire.

In fact, no elves can use magic in this pure metal hall while the Locks are in operation, and the sheer power of the Locks Circle can completely interfere with the caster's control over the magic, and all repairs and cleaning operations rely on manpower.

Because long-term exposure to the Mystery Lock Circle will inevitably lead to a regression in the caster's strength, the maintenance of the entire Mystery Lock Circle is handled by non-transcendents.

They must have a considerable reserve of magical knowledge, be able to understand the magic pattern circle, etc., in addition to not being able to sense magic power, the maintenance personnel of the magic lock circle are equivalent to a solid foundation mage, such elves are generally called scholars.

Xu Yichen had already seen them, seven or eight elves dressed in robes similar to spellcasters, but with differences in details, lying inside the metal hall, their corpses being a silent mockery of the elven system.

Beside the entity were carved knives, solidified Mithril nuggets, magic paint used to block the path of the magic pattern, and so on, and it was clear that they were responsible for the damage to the Mystery Circle.

These elven scholars, who were exposed to supernatural powers on a daily basis, but could never become transcendental, became Tzeentch's most loyal followers, and they were among the first members of Julius to corrupt.

In the center of the hall was a bird's nest-shaped object woven with precious metal, and with Xu Yichen's shallow knowledge of magic, he could see that there was something that should have been placed in the bird's nest, and that thing was used to drive the Lost Lock Circle, and even the energy source of the entire Silver Moon City.

The Demon Hunter didn't rush into the metal hall, he didn't want to aggravate the damage here, maybe in the future, the scientific officers from the Loess Region would be able to restore the complete Mystery Lock Circle through the rest of the circle, and he borrowed the corpse near the nest to determine the approximate volume of the contents of the nest.

Whatever it was, it was at least larger than a main battle tank, and a few Elven Scholars couldn't have disassembled something that big.

Xu Yichen finally gave up using his camera-style memory to record all the information of the magic circle, which would most likely blow up the memory space of his brain.

With this level of magic circle, I'm afraid it will take several months of research for Shuma Crane to determine which ones are the main magic patterns and which ones are the 'useless things' attached by the elves.

You may not believe it, but the Mystery Circle not only provides protection for the elves against chaos and other external threats, but also provides the elves with a mess of functions such as lighting control, temperature control, traffic command, and more.

The devil knows what the spellcasters of the Elven Court were thinking back then, with the precarious war situation on one side and the twenty-four-hour hot water for the residents of the war fortress on the other.

It's really elf.

In the spirit of the thief's obsession, the Demon Hunter swept through all the paper materials, magic scrolls, and small items that seemed valuable he could find, and completely filled his space equipment.

As for the rest of the things, it can only be decided when the army of the Loess Region enters the country in the future, if Silver Moon City can hold out until that time.

On the way back, Xu Yichen found two headless corpses, one of which was dressed and figured exactly the same as that of the elven archon, based on the current situation, the demon hunter was quite sure that this was the corpse of Kael'thas.

He used [Pure Fire] to purify two corpses, which was considered a recognition of him.

Xu Yichen is accustomed to seeing death, and he has no superfluous emotions about it, and the death of Kael'thas will help the Loess District to fully control the city from the perspective of the overall situation.

"Boss Yang, we are now sure that the enemy is fifty meters underground under our feet, but the only way to enter there is inside Silver Moon City, and an elven mage has entered the city before, and there is no news back so far." The swordsman Wang Yue reported upwards: "The head can't be contacted, are we waiting here for the opportunity to fight?" Or hurry up and retreat? ”

"How did the elves dig fifty meters deep and then fill in the hole?" Yang Yuefan had to take over the command remotely, and the interference behavior of the chaotic forces on the player's communication plagued players all over the world.

"It used to be a natural underground cavern, and the elven mages detected it through sonic spells, and then used teleportation spells to transport the workers there, expanding it from the inside out, and all people and materials, including air, entered and exited through portals." Warrior Monk Feng Wuyi explained: "Now the portal there should have been destroyed, we have destroyed the ventilation system, but the elves have set up an oxygen-related circle underneath, and they have also fixed the underground space with dimensional anchors, and it is impossible to enter through the teleportation circle again." ”

"Didn't they think about this today?" Yang Yuefan began to feel a headache: "It's just that I can't get along with myself, these elves." ”

"Dig down from above, we still have sixty hours." The news of the Demon Hunter suddenly appeared in the channel.
