Located in the very center of the entire Northrend continent, the Crystal Song Forest is a proper place for the four wars, and it is not so easy to gain a foothold here.

Fortunately, with the relationship between Salian and the Dragons, the city of Shinsudara does not need to worry about the threat from the Southern Dragonbone Wilderness.

Through Stellagosa, Salaen enlisted the Blue Dragons to help the High Elves who had resettled in the Lattice Forest for thousands of years to readjust the structure of the local magic web.

Back in the days of the Night Empire's existence, this area, which was then known as the Moon Song Forest, was the inherent territory of the elves, and the ancient city of Sandara, one of the six major cities of the Night Empire, was located here.

Due to a series of subsequent events, the Moon Song Forest triggered an arcane explosion of unprecedented scale under the death of the upper elves, and a large area of the forest was crystallized by the raging arcane magic, evolving into the current Crystal Song Forest.

Years later, Druyin, led by Vandal Deerhelm, planted a rune tree in the western part of the Crystal Song Forest, where the structure of the web had changed dramatically due to the impact of an arcane explosion.

Originally, Vandal intended to use the Rune Giant Trees planted throughout Azeroth to supplement the growth of the World Tree Andahir, the crown of the Snowy Plains, and to curb the spread of the Saron Evil Iron Vein.

Unfortunately, Andahir's roots were too deep into the land of Northrend, and they accidentally touched the prison of Yogsaron, providing the perfect opportunity for the Elder Gods to invade the Emerald Dream with the help of the World Tree network.

As a last resort, Vandal and the others could only endure the pain and cut down Andahir.

Although Andahir was cut down, the few rune trees planted by the Druyin were retained, and were later taken over by the Green Dragons.

That's right, the location of these rune trees later became the node that connected the physical world to the Emerald Dream, and the Shade of the Gray Valley, which is now being watched by Manolos, is one of them.

Vandal Deerhelm is a stubborn man who has caused great harm to the Emerald Dream because of his hasty and reckless behavior.

Even thousands of years later, Vandal still haunts it.

There is a good saying that where you fall, you must get up.

During the time he was commissioned to explore the Soracha Basin, Vandal realigned the World Tree Network plan, which had been developed thousands of years ago.

Akandol, the miracle tree that Salian and the Valley Walker Farodin cultivated in Sulama, gave Vandal a lot of inspiration.

With the help of Akandol's ability to reconcile different energies, Vandal enthusiastically carried out a variety of experiments on the Miracle Seed, and successively obtained some results.

It is thanks to the efforts of Druyin such as Vandal and Farodin that the production of Akandol dishes, which had an impressive yield, has been able to increase year after year.

Today, with the full popularity of Akandol, the harm of the magic addiction that once made the elves talk about it has long disappeared.

After solving this major problem that plagued all the elven sub-races, Vandal was still dissatisfied and turned his attention back to the World Tree Network project, which had suffered a huge failure many years ago.

The original Akandol reconciled arcane and the forces of nature, and in theory, it should be able to use the gentle forces of nature to reconcile other energies after modification.

For example, the power of the Void.

Objectively speaking, the World Tree Network plan formulated by Vandal back then was not a complete failure, and Andahir did effectively curb the brutal expansion of the Saron Evil Iron Vein.

Thousands of years ago, the Council of Cenarion conducted an in-depth analysis and study of the composition of the Salonite Iron Ore.

This ore is not native to Azeroth, but contains a trace amount of the power of the Void, a deformed byproduct of the power of the Elder Gods escaping from their cages.

To this day, there are still some Ssalonian iron ores growing sporadically on the land of Northrend, but they are far less harmful to Northrend than they were back then.

That being said, in Vandal's words, these Salonite Ironores are essentially the "eyes" of the ancient gods imprisoned in their cages to observe the outside world.

When he failed to do his best, Vandal never forgot it.

Last year, Vandal made a deal with Sarjan, and the Druins were given permission to enter the Crystal Song Forest to improve the Rune Tree.

Vandal's experiments are also of great use to Sarjan, and Queen Ayshara is still waiting for the Druyin to develop a new type of Akandol that can reconcile the power of the Void, which is a win-win deal.

Vandal is a pragmatist through and through, and Marfurion and Tyrande fear that Queen Azhara will take control of the Night Elves upon her return, but Vandal doesn't care.

He didn't care who the Night Elves were at the helm, only that person had the ability to lead the race and the nation to continue to grow.

After more than a year of hard work, Vandal has succeeded in improving the Rune Tree in the Crystal Song Forest, forming a network that resonates with the improved Akandol he planted in other parts of Northrend.

After months of observation, Van Dahl can now proudly pat his chest and announce that his World Tree Network project has finally made phased progress after thousands of years.

Within the resonance network of the improved Akandol, the Saron Evil Iron Ore, which is the Eye of the Old God, quickly lost its activity, and the trace amount of Void power contained in it was also transformed into mild non-attribute energy under the harmony of the power of nature.

After all, the Crystal Song Forest and the island of Queldanas where the Sunwell is located are far away, and even if there is a magic network pipeline that has been transformed by the blue dragon to transmit energy, there will still be a lot of loss in the process of energy transmission.

As a result, the simplified version of the Bandy Norrell Barrier that shrouded over the Crystal Song Forest was much lower in terms of output than the original one in the homeland.

With the Transformation of Saron Evil Iron...... In other words, the large amount of non-attribute energy obtained by Yugsaron infiltrating the void energy of the land of Northrend has been greatly enhanced by the simplified version of the Bandi Norrell Barrier centered on the city of New Shandara.

To this day, the entire Crystal Song Forest can be covered by enchantments, including the Iron Wall Dam built by the High Elves on the border with Icecrown.

Due to the difference in topography, there is a large waterfall on the border between Icecrown Glacier and Crystal Song Forest.

Before the High Elves settled in the Crystal Song Forest, the waterfall would return to its normal flow during the relatively warm summer months in Northrend.

The formation of this waterfall has created a small lake on this side of the Crystal Song Forest, and a stream that flows through most of the Crystal Song Forest, bringing valuable water resources to the crystal grid forest.

In winter, the upper reaches of the waterfall are frozen by the extremely cold climate of the Icecrown glacier, creating the spectacle of a frozen waterfall.

Influenced by a simplified version of the Bandi Norrell Barrier, the Crystal Song Forest is like Quel'Salas itself, and the climate has become spring-like.

The original spectacle of frozen waterfalls never existed again in warm climates, but with it came the problems.

In order to defend against the possible attack on the Crystal Song Forest after the rise of the Scourge Legion, Sarian proposed several years ago to build a strong dam on the upper reaches of the waterfall before the Scourge began to expand externally, transforming it into a military base capable of garrisoning a large number of troops.

After the proposal was approved by the Sun King Kael'thas and the cabinet, and thanks to the efforts of the two successive Lords of Shin Sandara, the increasingly strong iron-walled dam made Naozu, who was interested in expanding his territory, feel like a fish in his throat.

From the topographic map, Icecrown Glacier is bordered by the Soracha Basin, Dongyong Lake, Jingge Forest and Storm Cliffs at the same time.

But in reality, Naozu's options for the route of external expansion are quite limited.

At first, he planned to take the nearby Crystal Song Forest, which was located in the center of Northrend, and then he could attack and retreat.

However, the High Elves who arrived in advance to occupy the place did not give him any chance, whether it was digging a hole from the ground or sending a gargoyle to raid from the air, the High Elves were impregnable under the command of Wen Lessa.

So Nao Zu changed his mind and planned to go south to take Dongyong Lake, and then unsurprisingly he was beaten back by the High Elves who had been prepared for a long time.

In desperation, Naozu had no choice but to try in the Soracha Basin in the west.

For a while, Neozu thought that his plan to invade Soracar had succeeded, and that the Night Elves, who were busy exploring the territory, failed to detect his small operations underground.

However, just as Naozumo was about to make more efforts, Sarian jumped out in time and slapped him in the face to tell him......

"No, you don't."

What? Why not head to the Storm Crags to the east?

Although Naozu has a worrying big picture, he is at least not a complete idiot.

Anyone who is begging for a living in Northrend should have the most basic understanding - Storm Crags are the inherent territory of the Titan Guardians, and unless you are extremely confident in your own strength, you should not easily enter this Guardian's own territory.

Otherwise...... Lorcan, who turns on the Creator Engine Riot with all his might, will give you a sense of what it means to be made by Titan.

There is no hope of external expansion, and the incompetent and furious Nao Aozu can only go all out to develop within his own one-third of an acre.

Compared to when Neozu was first thrown into Azeroth, Icecrown is now a much different glacier, and there are man-made facilities built everywhere by the undead who are not afraid of the cold and heat.

"Hiss~"

Standing on the top of the iron-walled dam shrouded in enchantment, Solas, who had long been out of breath, subconsciously gasped.

"This ...... Can such a majestic fortress be built on a glacier with no roots underground? ”

The Icecrown Fortress that towers over the southwest of Icecrown Glacier is almost complete, and the steel required to build the fortress is from the Saron Iron Mine, and the cold steel façade is all blue and black.

The Frozen Throne where Neozu is located is still an open-air structure, but it won't be easy to climb up, requiring you to break through the Lich King's carefully placed defenses.

At this time, the demonic army under the command of Tikdios is attacking south from the secret base of the Burning Legion in the north of the glacier, showing the defenders of Azeroth for themselves how strong the defenses that Neozu has spent years building.

Winresa was accustomed to this, but the expressions of Soras, Daelin, and Alonsos, who saw this scene for the first time, were very solemn.

"Ahem...... Dai Lin coughed lightly for a while and then asked with some distress, "Although this demon army is not the main force of the Burning Legion, it seems to be very strong. ”

"Even the Burning Legion can't break through this impregnable line of defense in a short period of time, how can we quietly send Solas to the depths of Icecrown to challenge the Lich King?"
