To be honest, for these invaders from the Otherworld, the most valuable thing about them is probably the knowledge of the Otherworld, which is completely different from the wizarding world. 『』

It can be seen that these invaders should come from a plane world far higher than the wizarding world, where there is a far more comprehensive and profound system of spells than the wizarding world. This can be seen only by the remnants of their undead transformation witch array and cursed witch array.

Among the major wizarding organizations in the wizarding world, except for the Northland Witches and the Silver Alliance, who sincerely want to completely eliminate these invaders, the rest of the wizarding organizations and forces want to capture these invaders and extract the most valuable knowledge from their souls.

It's a pity that these invaders are all as cunning as foxes and cautious as rats, and they are actually running around under the pursuit of major forces, fanning the flames everywhere. I heard that the terrible plague that ravaged the Kthlinburg region some time ago was their handiwork.

Now that this notorious singer of death had run to the Rock Castle, needless to say, it must have come for the burning plains. This could not help but amaze Josahi in great amazement.

Inside the Burning Plains is a forbidden ancient battlefield, where there are many spatial rifts and the living environment is extremely harsh, but there are still some remnants of demon descendants. What does this death carol singer want to run to there?

Go to the abyssal world with the help of a spatial rift? That's just a joke!

According to the conclusion of the great witch god's personal investigation of the Nether, the spatial rifts there have been shattered, and there is no way to find a safe passage through the space. If this death singer really wants to break through those spatial rifts, he is purely looking for death. Not only will he not stop one or two, but he can't wait to hold a farewell party for him.

He will definitely be crushed by the dense space fragments in a certain spatial rift.

Knowing this, Yosahi's heart suddenly moved, and he couldn't help but ask curiously, "What kind of knowledge can you provide?" ”

The weeping grimace glanced at Yosahi's body covertly, and replied in his cold and gloomy tone:

"Taboo on Transplantation of Superior Organs of Magical Energy", written by the legendary mage Joseph 1200 years ago.

"Human Body Modification", the work of the great ** teacher Wimball 700 years ago.

"The General Guide to Otherworldly Creatures", the basic monster theory that the master needs to master.

"Astral Origins", the great work of the legendary mage Blair 900 years ago.

……

……”

The 8-ring Great Wizard Yosahi instantly held his breath, his eyes narrowed into a slit, and his body, which looked like an ordinary person, unconsciously expanded a little more, and a certain part of the consciousness hidden inside the body actually had a tendency to activate.

Not only him, but even Halvers, who was lying on the ground silently, suddenly brightened his eyes, and all kinds of anxious and contradictory expressions of struggle appeared on his face.

Although the other party has not been exposed to the profession of mage and great ** master, the word legend is still common in all plane worlds. The value of the experiences written by these legendary professionals is far greater than what their level can reach.

After all, the wizarding world is a primordial, obscurantist primary-plane world, far behind the Klein plane in the process of induction, combing, and systematization of knowledge. The Crane Plane has gone through three spell eras, mage, arcane and then mage, and the current mage system has been born after several ups and downs. Compared with the wizarding world that has just escaped from the era of totem and ancestral spirit confusion, in terms of the precipitation and popularization of knowledge, one is indeed heaven and the other is underground.

The world has been precipitated for six or seven thousand years!

In the Crane Plane, this knowledge is precious and rare, but only if you have enough resources and financial resources to take it all into your pocket. In the wizarding world, all kinds of rare knowledge are usually only exchanged in a small area, and it is impossible to circulate on a large scale among the major regions where wizarding organizations are numerous. As for those legendary-level knowledge, it is the core of the monopoly and hoarding of major organizations, and it will not circulate outside at all.

Although the 8-ring wizards like Halvers and Yosahi are affiliated with a large family in Tallinn in the east, they are not affiliated with any large wizarding organization, so the level of knowledge they can obtain is becoming more and more limited. Unless they are willing to give up their freedom altogether and allow the large wizarding organizations to plant contracts in their souls, such core knowledge will never be accessible to them.

At this moment, hearing such a gripping knowledge of the other world in such a remote and desolate wilderness, the two 8-ring great wizards couldn't help but snort a little.

If at this moment, the Karthus body was in front of the two of them, the two great wizards would not help but say that they would take out all their abilities and take it completely, and then squeeze all the knowledge out of their souls. It's a pity that what is now revealed in front of the two of them is just a strange and unspeakable crying grimace, and that Karthhas has also revealed a terrifying strength that is enough to make the two of them awe.

In this case, whether they can get what they want or not, the two great wizards are also a little undecided.

True peace can only exist between two evenly matched entities!

In this game, the strong strength of the two 8-ring wizards made Karthas understand that even if he could take this rock battle castle smoothly, he would probably have to pay a lot of sacrifices. And Karthas, who seems to be lonely and has few reinforcements, also used his proud strength to make the two great wizards understand that even if they fight to the death, it is difficult to change the predetermined outcome in front of them. Instead, it is better to use your identity and take advantage of the current good situation to get enough benefits for yourself.

The people behind the scenes of the two sides negotiated in the underground secret room, and near the underground tunnel, an even more ferocious and bloody battle was also going on at the same time.

This is also a tacit understanding between the two sides.

That's the end of tonight's battle. The high-end forces of both sides will no longer be involved in the subsequent war, and all that remains is the battle between the undead legion commanded by Karthas and those middle and low-level wizards and guardians.

If the undead legion breaks through all the defenses of the Rock Battle Castle, then the chips in the hands of the two great wizards will undoubtedly be reduced by half, and the knowledge that can be exchanged will be reduced by half. And if the wizard's side wins, the two great wizards who occupy a favorable position will of course turn all their advantages into bargaining chips and dig out more and more valuable knowledge from the hands of Karthus.

As a result, a life-and-death battle that mobilized all the forces of the Rock Battle Fort and fought to the death between the two sides unfolded under the game-like gaze of the high-level of both sides.

How do the warriors who fought on the front lines of the battle know that they are just pawns on the board of a game. Their heroism written with their lives and blood was eventually replaced by cold numbers from the main messengers behind them, and became simple bargaining chips for chess players to play with each other.

Perhaps this is the sorrow of the weak!

The battle ended in the end.

The guardian wizards who stood firm on the defensive line cooperated with the defenders to finally annihilate the incoming army of the undead, but they also paid a heavy price for it. Even nearly half of the more than twenty middle- and high-level wizards died, and the rest of the people left behind could be imagined. The original 400-strong defender team was left with less than 17 people after the battle, and those low-level wizards were even more dead and wounded, and the entire rock battle fortress was a gloomy fog.

Compared with the miserable desolation of his subordinates, the two great wizards were smiling and earning a full bowl. If it weren't for the possible organizational investigation, I'm afraid they couldn't wait to hide in the secret room to delve into the newly acquired core knowledge of the other world.

It wasn't until after the war that the two archwizards made an appearance inside the Rock Castle. He treated the wounded, comforted the dead, restored basic order in the Rock Battle Fort, and sent people to burn the town of Paran under the pretext of preventing the resurrection of the undead...... One by one, one by one, the two great wizards sat in the center and methodically began to erase the traces that were too conspicuous.

And no one knew that Karthas had gone deep into the Burning Plains at this moment.

……

Crane Plane, Warcraft Continent.

After the most difficult development period, the city gradually gained some popularity.

With the erection of several functional buildings one by one, and the completion of auxiliary facilities such as mission halls, town halls, taverns, markets, etc., some impatient undead mercenaries who can't hold back their curiosity have begun to explore and develop the magical beast resources around Yin Feng City.

I have to say that the Warcraft Continent is worthy of being a continent dominated by Warcraft, and the Warcraft resources here are really far beyond the imagination of outsiders.

Any piece of water with fertile water, any steep peak, any deep valley, you can find traces of demonic beasts in it. From the wind eagles, gale eagles, bipedal dragons, and chimeras flying in the sky, to the ironclad rhinos, earth storm bears, razor boars, and rampaging baboons running on the ground, to the strange and bizarre insects and purple insects, the Fumi ant clan, and the vampire spiders, as well as the extinct owls, sharks, lizards, and griffons in the main continent......

It can be said responsibly that all the Warcraft that can be described in the "Biological Guide" can be found here, and there are even many mutant varieties that are not included above.

However, many undead mercenaries today are not busy hunting, but are reunited near the portal, waiting for the arrival of a new strange creature.

Some time ago, the two Acting City Lords teamed up to destroy a druid village, seized a batch of precious magical materials, and sent them back to the Undercity. I heard that today, some of the new combat members who have been successfully transformed by the many corpses of the Undercity will return to the Underworld and become the Great Graveyard's weapons against those jungle creatures.

Finally, in anticipation, two extremely mysterious Cemetery units appeared in the Windy City.
