In fact, the large group of underground immigrants led by Fischer was not the first echelon to arrive.

Construction workers who were building the Beiyou Tunnel had already started using their steam locomotives to build a temporary stronghold in the mountains almost as soon as Li Wei and the others left the Griffin Mountains.

So when those underground immigrants who originally thought they would see desolation just walked out of the portal, they saw the first scene, which was in front of a dangerous mountain peak, more than 300 steam locomotives of various types were spewing white columns of air into the sky.

, working together to level the land at the same time!

This is what Li Wei means. In his impression, since the floors in Corel Continent are generally not high, there are no high requirements for the depth of the foundation.

But what he wants to build now is a majestic city that relies on the Griffin Mountain Range and is as high as five giant trapezoidal platforms that rise in sequence.

And considering the orc offensive and defensive battles that may be faced in the future, don't just place a row of catapults in a circle and then collapse. It will become a black joke throughout the entire continent of Corel.

Therefore, Li Wei's requirement for this city to resist beatings is directly based on its ability to withstand the invasion of the abyss.

That is, the kind of person who can persevere even if the demon lord summons a hellfire meteor shower to hit him.

This made Tiger, who was the chief technical engineer at the time, very worried. He said that even the gray dwarves' original Ironforge Castle did not have such perverted requirements.

But he didn't dare to say this, because he would probably come to a reasonable conclusion:

"This is probably the reason why your Ironforge Castle fell into the hands of the illithids."

What else could they say? Could it be that the illithid does not capture the city by force at all?

Instead, just use psychic control to turn the city lord into a puppet and gradually corrode it from top to bottom.

By the time the gray dwarves at the bottom realized what they were doing, the illithids had already taken control of the entire city.

But can he argue with his boss like that?

Isn't that because the old dwarf hanged himself because he thought his life was too long?

For this reason, Tiger did not hesitate to try to find a solution with the Moon Elves and Eagle's battle magic group who had experience in architectural design in this area.

In the end, he did find it, which was the blueprint for the construction of the capital of the Moon Elf's Erlan Ancient Empire in the Supreme Forest.

If it were more than 400 years ago, when the Erlangu Empire was still alive, such a good thing as pie from the sky would be unthinkable.

But with the establishment of Hellgate Castle and the massive invasion of Abyss Demons, the Erlangu Empire was destroyed.

Before this behemoth was about to be lost, the nobles of the Elf royal family were also preparing to transfer important items.

In order to prevent the design drawings from being lost during the transfer, the elf who was responsible for taking care of the drawings at that time used magic to make several copies of the drawings and gave them to his children respectively, so that even a few of them could be passed down over the years.

If it is lost, it can be preserved as long as there is a possibility.

As a result, this preservation, and the person in charge of it, was preserved in the Underdark along with its owner who was kidnapped by the drow.

I believe many people have already guessed who this unlucky guy is.

He is Lucifer's poor old father who worked himself to death.

But Zhuoer disdained things like design drawings.

They don't even expect to see the drow unite to counterattack the surface continent in their lifetime, so this kind of thing is basically useless to them.

Of course, if it is an original hand-drawn drawing by a high elf, it may still have good collection value.

But a fake like this that was engraved on parchment using magic? It’s too rough to even wipe your butt!

Therefore, this blueprint has been kept in the library of Madam Benjier, and no one has ever cared about it.

After Tiger communicated this problem to Lucifer, the latter remained silent for a long time. The next day, he got the blueprint and solemnly handed it to Old Tiger.

In his own words, he said: "This may be my father's unfulfilled wish. If it can be passed on and let Ye Erlan bloom in Corel again in another way, it must not be possible.

The father of the Kingdom of God, when he is in hell and looks up to the sky, he can feel relieved for the rest of his life. For him who has been fighting for his whole life, this is another situational victory."

At the same time, Lucifer also handed over the seeds of an ancient elf tree to Tiger.

That is the seed of the Grandfather's tree.

The spiritual symbol of the Erlan moon elves.

According to the details on the drawings, the capital of Yeerlan was built directly on the Lost Peak, which was also called the Sky Peak back then.

It's just that many of their design concepts and reinforcement methods are based on the roots of the Grandfather's Tree, plus the seeds of various ancient trees that are catalyzed by the Druid's magic.

They don't have the Grandfather Tree, nor the seeds of the ancient tree, nor the druids, but they still have a group of mages!

Some engineering problems that are usually difficult to solve can be solved cleverly through various magic spells.

This is why the various solid fortresses among humans are not the capitals of various human city-states, but the various mage towers where mages are full of fantastic ideas and put them into practice!

The high elves also used this idea in the two main elven cities before the Battle of Dragonfall.

However, their city defense relies more on their unique black magic - Mystery Lock.

On the blueprint, the three major secret lock construction technologies of the Yeerlan Empire were hidden in a single mystery lock. This was the unique capital for the high elves to stand in the world at that time.

I wonder if the drow would regret it and shut themselves up on the spot if they knew that the high elves' secret locking technology had been lying quietly in their bookshelves for nearly a hundred years, and then missed it because it was not taken seriously.

Anyway, after Li Wei learned about this incident, his teeth almost flew out of laughter.

But when I saw the material consumption required to build those mysterious locks, I instantly shut myself up on the spot.

Not to mention the magic materials that can easily consume all the savings of Zelandia for more than ten years. Two of the main materials are actually artifacts. Can you believe it?

He doesn't believe in God at all, so where can he find artifacts and sell himself to Lady Tiamat?

Is it okay to sell your body for less than the price of the artifact?

But after thinking about it, I feel mentally balanced.

Because as far as he knew, the magical mysteries at the top of Corell were indeed driven by artifacts.

For example, the Myth Myth Lock in Silvermoon City has its core from the destroyed Myth Drannor of Cormanthor. Although I don’t know what kind of artifact it is, it is probably related to Mystra and Azuth, the God of Magic.

And the core of the mystery lock of Silver Moon Dragon Mother’s floating mountain range ‘Soft Wings’ is the famous Alpine Crown.

The secret that makes the entire mountain range levitate is the permanent and constant [Advanced Levitation Technique] effect of this artifact.

Li Wei once saw it on the top of the Silver Moon Dragon Mother's head. Its appearance didn't even deserve the name "Crown".

It looks like a rough stone ring studded with spikes.

Its true origin may not even be known to its owner, the Silver Moon Dragon Mother herself.

Some say it was a gift from the dwarf god to his people, while mages tend to believe it was designed and made by the Warlock King of Netheril.

Because the first time it appeared, it indeed appeared in the hands of a great arcanist.

After Netheril was destroyed and lost, it was stolen from a human merchant by two dwarves and disappeared again.

When it appeared again, it became the treasure of the Dragon Queen Merogarland. A priest of Talos used divine magic to hollow out half of the archipelago's ground and stole it.

As for how it fell into the hands of Silver Moon Dragon Mother Vera Marendis, this is still a mystery.

According to some rumors in the North, it seems that the Silver Moon Dragon Mother met a dying dragon king and cast a spell to relieve her pain, allowing her to leave the world with dignity at the end of her dragon life, thus freeing her from the dragon king's death.

He inherited the crown and the territory of the North.

Even if we don't mention the preciousness and rarity of the artifact, just by looking at how many times this artifact has changed hands, we can tell how many powerful beings in the world covet them.

Therefore, Li Wei has basically given up on looking for the artifact, because even if he finds it at this stage, he can't keep it.

But fortunately Lucifer gave him another choice.

That is the seed of the Grandfather Tree.

As long as it is planted and casted, it can be linked to the mystery lock device of the entire city, providing a special enchantment blessing for the entire city.

But what hurts Levi is that before the grandfather tree grows up, the enchantment effect it can provide is pitifully small.

Before it reaches a hundred years old, it can only maintain an effect called [Life Activation], which can probably make the creatures in the entire city healthier and longer, and provide about 100% improvement to casters with healing spells.

10% increase in healing effect.

Even if it reaches the growth stage of the first hundred years, it is just one more spell to summon ten ancient war trees.

Li Wei thought to himself that this ancient war tree was probably not as powerful as the large trebuchets or even artillery they made back then.

Comparing the effect of Silver Moon Mystery Lock, it is simply a weakling, a fighter among novices!

"I don't know if I can use some method to accelerate ripening. I have to get the effect of a thousand-year-old tree to see it, right?"

Levi was floating in the air at this moment, frowning at Ye Erlan's design drawings, rubbing his chin and thinking.

After all, Netheril, the pinnacle of human civilization that was so powerful back then, the ancient elf country of Erlan, and the dwarf kingdom of Danzo, were all lost to the dust of history one after another.

He really had to be on guard.

There are too many threats on the continent of Corell!

For example, after the destruction of Netheril, the phaerimm was sealed by the Saren spirits with the [Wall of Saren].

The abyss demon army that destroyed the ancient elf country of Erlan.

The orc tribes who drove the dwarf kingdom to pieces due to the impact of Denzo gradually left their homes and turned to Cormanthor.

There is also the Dragon Cult, which was founded by Sammaster back then. It is a powerful force that controls at least four legendary dragon lichs.

If Lathander, the God of Dawn, had not come to this world in his incarnation to kill the leader Sammaster, God knows whether Silvermoon City would have survived the dragon disaster.
