Wren would never have dreamed that two people would be crooked like this after a word was heard.

The so-called layer by layer is nothing more than this.

In the four-kilometer tunnel, there are a total of six large passages and 41 small branch roads. In this kind of place, even if the entrance of the passage is built with bricks and stones of the city wall, it is not very safe.

After all, there are really many races in this world that have the ability to make holes. It is as strong as a mountain dwarf, and can only divide troops to guard this situation.

Wren was so busy that he didn't notice the slight fluctuations in the [Physical Network] and the small increase in daily mana consumption.

Triggered magic traps have this characteristic, and it takes a lot of mana to start carving runes, but once the magic trap goes into standby, the consumption is very small.

Seriously, Harry knows magic runes. Wren didn't teach either.

However, when the entire cave was engraved with the names of Joules, Archimedes, Heiko Onnes (the one who proposed the concept of absolute zero) and other physics bigwigs, and then used [Anti-Chaos Circle] and [Anti-Evil Circle] as triggers, Harry was stunned to make a process of ignorance and still achieve the effect of the goal.

Ahem!

Anyway, maybe that's what Wren did when he made Towns an assistant coach.

No, this also has Wren's pot.

Wren was punished for copying the book, but Harry was able to comprehend (double casting) and create his own supermagic specialty (modular casting). Harry doesn't dare to cheat with these two things, but now he is working for his master, so why not?

Harry became more and more energetic, except for eating and sleeping, and soaking in this matter for 18 hours a day.

In just one week, the cave complex was completely transformed.

What's more, the temperature in this cave is low, and many places will freeze. When the walls of the cave were covered with frost, it was impossible to see what had been carved into the stone walls.

Interestingly, Wren didn't know what his second disciple was up to.

The Earl of Lamancho and the Archduchess Sophia had actually asked him separately.

"Archmage, can you really guarantee the safety of this tunnel through the mountain?"

"Of course! I had already made arrangements. Here, Wren is talking about the system helping to monitor the conditions around the tunnel. In Wren's opinion, the tunnel was stopped when necessary. He himself and his disciples went into the caves around the tunnel to clean up, and that would be enough.

Wren is not focused on defense enough, mainly because he has more important things to do.

As the system said before, the first round of exploration of the system was completed after the entire Duchy of Marino became a legendary physical land.

Wren was disappointed that he didn't detect any fragments of the net.

Wren was a little distressed.

The real upper limit of the [Physical Network] is 5 people, such as the enhanced power obtained by the likes of Saunders, which is all incidental.

Without the assistance of the [Physical Network], the ordinary mages he taught in the future would be really ordinary.

This is not in Wren's interest.

He knew it wasn't going to happen.

Unexpectedly, on the 10th day after the cave was opened, when the adventurers of Raman Cho City handed over one after another, saying that they had completed the exploration of the cave and submitted a detailed map of the cave within a five-kilometer radius of the tunnel, Wren received an intrusion alert.

The territory was so large that Wren had to classify the alarm system of the Academy's security department. If something happens in the small valley, it must be a red alert, and the main city of Marino and the surrounding towns will be orange, and only the recently specially marked Ma(Rino) La (Mancho) tunnel will use a yellow alert.

Now it's yellow.

"Huh?"

The large number of red dots in the topographical map of the cave woke Wren to his senses.

There are thousands of them.

Even if the other side is full of miscellaneous soldiers, this is a large-scale invasion.

Wren was furious: he couldn't use fire bats in this frozen cave.

At this moment, in a fairly spacious cave 10 kilometers northwest of the tunnel and minus 150 meters above sea level, a group of dark elves were cautiously moving forward.

The leading woman, Drow, covered her slightly aching head and said, "It's probably safe here." Those bastards won't chase this side. ”

The other female Drow smiled wryly, "They're not chasing, but we should be very close to human territory." ”

"Be careful, don't go any further southeast, if I'm not mistaken, a little more than ten kilometers in a straight line will be the human city of Lamancho. At this distance, we should be careful not to be detected by humans. ”

"Humph! Blame Lisan Chases Shambhala for that idiot! Even if she dies herself, she'll put that thing in the rebuilt 'cobweb of the mind' to plague us. ”

It all started with an accident nearly three months ago:

Very nonsensically, a portal opens in the dark underworld.

If we put the time back a hundred years ago, although this kind of bad thing was rare, it was not uncommon.

Before the end of the era, there were too many half-buckets of water, and the mages liked to use space magic to die. When these guys, who have some strength but are obviously not enough, open the portal to the underworld and catch the dark elf mastermother, the most normal outcome is that the mastermother takes control of the souls of these mages, drags them into Drow's territory, and turns them into outright slaves.

Drow will also gain a new spatial coordinate, allowing them to capture more human slaves.

This accident was very different from the previous ones.

In the past hundreds of thousands of years, the similar outcome of this kind of event is basically - even if the mistress can't get it, she won't suffer anything.

After all, in a drow group, none of the daughters who can become the main mother of the drow are simple goods. Not only are they scheming and ruthless, but they are also the most loyal followers of the Spider Goddess, and can use a vast amount of dark magic to destroy or enslave their enemies.

Things didn't change dramatically until the fall of the goddess of magic a hundred years ago.

In order to fight against the goddess of magic and steal her divine power, the spider goddess made a [shadow demon net] for herself through means such as white prostitution and stealing the laws of the magic web.

This Shadow Magic Web is a distorted dark replica of the real Magic Web, which enhances the power of shadow magic, enchantment, necromancy, and illusion magic.

The price of the seemingly very powerful Shadow Demon Web is that whoever accesses the Shadow Demon Web will be under the mind control of the Spider Goddess.

Not to mention lowering IQ, even the soul will be corrupted by the Shadow Demon Network.

As the last generation of magic goddesses hit the streets, the magic net collapsed, and the shadow demon network that adopted the same law was also affected.

It's like two databases using the same source code, and the main database is deleted, can you, the sub-database that has been connected to the main database, still run?

The spider goddess was implicated and hit hard.

I don't know whether she lives or dies, some people say that she has fallen, and there are also a large number of believers who insist that she does not.

Anyway, she hadn't answered the prayers of believers for a hundred years.

In order to maintain their dominance in the dark underworld, the Drow hostesses teamed up to create a [Soul Cobweb] that weakened N grades. It no longer has the ability to grant magic, and is left with only one function - to control the minds of the rest of Drow.

In the accident three months ago, the housewife surnamed Shambhala missed and was driven crazy by the enemy. Before committing suicide, she was in line with the concept of pitting goods with disaster, and transmitted a [ideological and political] to the spiritual network......
