Arcane Lord

There are two difficulties -

First, the Elan region itself is not small, and the specific location of the Underdark passage is unknown, so it can only be checked one by one. Even with geological experience, the workload of the check is still quite huge.

Secondly, the Illuminati will definitely not let the Alliance find their location easily, and they will inevitably cover up or mislead the key Underdark passage.

Combined with these two difficulties, it is almost impossible to find the Underdark passage in the Elan region in a short time.

Now on the ground of Elan, the Yeerlan army originally stationed here has been searching inch by inch, but the efficiency is pitifully low and the progress is pitifully small. No matter how many soldiers come, the area of ​​nearly two square miles cannot be filled.

What's more, not all soldiers are good at spells, let alone detection spells.

So now, only Shado can come here in person to challenge the impossible.

He used [Wide Area Detection] right away. The robe of thoughts is indeed more advanced than that of Yongle City, but the spell of [Wide Area Detection] itself is no different, just like 1+1 written with atoms and 1+1 directly unloaded on paper, there can be no two different results.

As long as the specific implementation scheme of the war spell [Wide Area Detection] does not change, no matter what carrier it is loaded on, the effect is the same. However, because it is loaded on a single-person magic weapon, the actual operation will be more complicated than the multi-person operation of Yongle City.

But in any case, as a war spell attached to a single-person magic weapon, it is still stronger than the spell cast by any individual caster.

In terms of detection, although Xia Duo came alone, the data fed back by [Wide Area Detection] can still be synchronized to the Lingsi network for other mages to analyze.

He himself plays more of a role as a detector. Originally, he could also control the robe of thoughts to detect the Elan area at the alliance headquarters. The effective range of [Wide Area Detection] is very large, enough to cover the Elan area.

But he still came in person.

The main purpose is to personally feel that the subconscious of intelligent creatures has an almost miraculous ability to process perceived information, and thus things such as [intuition] and [inspiration] are born.

Just looking at the feedback data of wide-area detection, this spell itself will not process the data, and the caster still needs to analyze and summarize.

Since the feedback of spells and the feedback of the caster's own perception ability are different, although the former includes more information, covers a wider range of dimensions, and has higher precision, it is still a machine after all.

Before establishing a sufficiently good data analysis algorithm, the caster's own [intuition] may sometimes be more effective.

Xia Duo does not blindly believe in intuition, and often does not even believe in intuition at all, but will directly trace the most fundamental subconscious information, but he also has to admit the value of intuition.

Especially in the current situation, it is better to have intuition than not, and it feels a bit like a last resort. This is the main reason why he came to Elan in person.

...

After debugging the various parameters of [Wide Area Exploration], Shado stopped caring about it. All the feedback data will be synchronized to the Alliance mages in the rear, including experts in the field of geology and even elven mages who have been to the Underdark.

Of course, this kind of work cannot be done without the dwarves who have been dealing with land and rocks for many years. In fact, the dwarf mages are the main force in this analysis. They can analyze the possible location of the Underdark passage from the geological direction.

Thus breaking through the disguise or misleading that the Illuminati may set up.

Confirming that [Wide Area Exploration] is in the activated state, Shado found a suitable place in Elan by feeling, and used the [Stone Walk] learned in the projection plane Underdark to transform into earth and stone, and continue to dive underground.

The total area of ​​the Elan region is nearly 20,000 square new miles, which is approximately equal to a rectangle with a length of 200 new miles and a width of 100 new miles. It does not seem to be particularly large, but if this distance is placed underground, it is quite deep.

You should know that the deepest mine on earth is only more than 4,000 meters, and it is just a well that gets smaller as you go down.

The depth of the Underdark is generally thousands of new meters underground (new meters are approximately equal to meters, new miles are approximately equal to kilometers, and Xiaduobi uses the measurement unit based on the feeling of one meter).

In other words, if the smallest span of 100 new miles in the Elan region goes down, it is enough to reach the Underdark, but can the difficulty of detecting one thousand meters underground be equal to one thousand meters on the surface?

Obviously not.

Underground, there is not only the barrier of the earth itself, but also the ubiquitous ground vein radiation, which is mixed in the background fluctuations of the magic network. This radiation is different from the radiation of the Underdark, and the characteristics are not obvious, and ordinary people can't perceive it at all.

Especially on the surface, even in the area where the ground vein nodes are located, almost no ground vein radiation can be felt, but underground, it is different. The deeper you go underground, the stronger the sense of the presence of ground vein radiation.

Perhaps this is also the reason why Richie the Divine Envoy believes that the radiation of the Underdark is a special ground vein radiation.

This shows that the difficulty of exploring the underground world is by no means comparable to that of the surface or the sky. If we can fully understand underground exploration, perhaps the magic civilization will not be far from penetrating the essence of the plane.

There is a saying on Earth, which is actually a fact, that is -

The so-called deepest mine on Earth has not even penetrated its surface, let alone penetrated the core of the earth.

This is similar to the magic world. The Underdark is almost infinitely deep. Of course, this is just a description. The shallowest layer of the Underdark is about thousands of meters below the surface, and the deepest may be hundreds of miles.

So far, no wizard has really reached the deepest part of the Underdark. Often after reaching a certain depth, either the way forward is cut off or it falls into eternal annihilation. Not only is there a lack of survival supplies such as food, water, and light sources, but even the magic network will change and become vague, but this is still not the limit of the Underdark.

Even if you reach the deepest part of the Underdark, it may only be a layer of skin compared to the entire underground world of the main plane.

However, with Xia Duo's current research on the plane field, he can still make a certain judgment on what the deepest part of the underground world is like.

It is roughly similar to the deep and even undetectable depths of the trench. In those places, the form of elements is no longer limited to matter or energy, but is in an intermediate state.

Or it can be said that there is the surface of the real elemental plane.

Just like flying from the surface to the sky, after breaking through that plane barrier, you enter the [boundary between existence and non-existence], and if you continue to go out, it is pure nothingness, which is the so-called [etheric layer].

Or the surface of the etheric plane.

By the same logic, if the boundary between matter and elements goes a little further to the element side, it should be the surface of the elemental plane.
