Although it is said that Kil'Gardan was very powerful before the siege, and directly destroyed half of the Celestial Dynasty's counteroffensive plan, Kil-Gardan did not expect that Shirai Moon would use the peculiarity of this world to repair the Frost Grief and use it to rapidly expand the scope of the undead disaster.

Using the few planes and the Queen's fleet in the academy city, the coalition forces gathered inside the academy city were divided into six parts.

Two of the sections are made up of most of the undead, fighting the Burning Legion head-on, in order to constantly attract the attention of the Burning Legion and create a large number of corpses by the way, and these two parts are led by Lola and Aresta respectively.

That's right, it's Aresta, although Aresta's power has weakened after becoming an undead, but this does not affect the fact that he was once the greatest magician in the world, and it is normal for him to lead an army.

As for whether Aresta is willing・・・・・・ if nothing happens to the Lich King, the Lich King's power is absolute, especially now and not the same as in the past.

In the past, the Lich King used Frostmourn as a device to connect his souls with Arthas, and it was his own power to control the undead, but Shirai Moon used a ritual unique to this world to give this power to Frostgrief and the Lich King, respectively.

When there are more and more undead, the stronger the power of Frost Grief becomes, and the stronger the control over the undead.

However, Shirai Moon doesn't pay much attention to this, after all, his goal has always been to protect the things he cares about.

There are also two parts of the elite troops of the Misaka sisters who guard the network that forms part of the artificial celestial realm, and they are responsible for the early expansion of the power of the undead natural disaster, in any case, the current frost grief has only been recognized by the artificial celestial realm, although it is okay to move to the current world, but it is not sure that all the undead are controlled, and once the undead are out of control, who knows what will happen?

Therefore, it is necessary to rely on the artificial celestial realm to expand the realm of the undead natural disaster to increase the number of undead.

The last two parts are Shirai Kuroko and Yuki Tamki.

The two of them are each equipped with a part of the formation cultivation, and there are also the flying Emperor Gengaki and Zuotian Tears as a means of insurance.

Emperor Negaki followed Yubiao Tanxi, while Satentearko and Shirai Kuroko, two parts of the men and horses went to the interior of the enemy-occupied territory to destroy the portal.

Because the action has a certain degree of danger, the two Level5 of Negaki Emperor and Satian Tears are the last guarantee when the situation changes.

After receiving the task, Mikoto Misaka and the others were still a little worried about Shirai Kuroko, Shirai Moon didn't want Shirai Kuroko to perform such a dangerous mission, but before Shirai Moon failed to support the undead natural disaster covering the world alone, Shirai Moon couldn't act on his own, he had to stay in the artificial heavenly realm, and feel the new power of Frost Grief, and control it!

However, in this case, the expansion and stability of the artificial celestial realm is necessary, and within the artificial celestial realm, the existence of the portal is a threat, and the destruction of the portal is a necessary action.

And those who can destroy the portal without attracting attention are the two spatial abilities who are already infinitely close to Level 5.

As for those formation cultivators, although they can also destroy the portal, they can't complete the goal quietly and silently, and if the formation is destroyed before the formation is completed, they won't be able to complete the set goal.

However, the spatial ability is indeed very powerful, and in just one month, the portals in Australia and North America have all been closed.

After the portal was closed, there were no constant reinforcements, and under the tireless and life-and-death undead scourge, these areas were quickly reclaimed, and the number of undead legions increased explosively.

And a month also made the form of the Celestial Dynasty stable, and with the efforts of countless people, it was finally solved that big guy was raging in the territory, and successfully stabilized the battle line.

Although there are many demons in the Burning Legion, during the Kyushu Barrier, the Celestial Dynasty arranged a large number of formations on the border just in case.

And because of the efforts of the academy city troops, the attack intensity of the Burning Legion on the south side of the Heavenly Dynasty has decreased a lot, after all, even the portal has been closed, and without the replenishment of the follow-up troops, the Burning Legion is a little unable to withstand it after a long attack.

This is just the beginning, and when all the portals in the world are closed, the Burning Legion here will be like a turtle in an urn.

Of course, this is in the case of being able to solve Kilgardan.

Another half a month has passed, and as the field of the Undead Scourge has become wider and wider, the speed of recovering the lost territory has become faster and faster, and with North America and Africa being resolved, the Burning Legion's attack on the Celestial Dynasty has decreased a lot.

Taking advantage of this opportunity, the forces of the Celestial Dynasty also invaded the territory of the former Russia on the northern side, and closed the portal in Russia.

At this point, only the portals in Europe and South America are still in operation.

On this day, Shirai Kuroko and several array cultivators came to a mountain cliff, and in the distance was a portal. The scorched earth is so much that you can't imagine the original prosperity here, and the invasion of the Burning Legion has wiped out a lot of things.

Beneath the cliff are the remains of a large number of buildings, and from inside the portal, the troops belonging to the Burning Legion continue to emerge.

"How many troops are there in the Burning Legion・・・・・・" Shirai Kuroko muttered, until now, the Burning Legion is still expelling troops from this world, and it has never stopped.

"No one knows, just as no one knows how many worlds the Burning Legion has ruined. ”

Even at this moment, when the world is about to recover, Satian Tears is still full of sadness, and to this day, the bee-eater Cao Qi and Satian Tears are still worried about Shirai Yue's "death period".

After the monks who followed him here attached a lot of invisibility and breathing spells to Shirai Kuroko, Shirai Kuroko began to use his superpowers to approach the portal.

The method used by the Celestial Dynasty Formation to destroy the portal is to use the leylines to interfere with the flow of magic in the portal and make the portal ineffective, while the other method is the one that Shirai Kuroko is doing.

The portal of the Burning Legion itself has a certain defensive ability and can resist certain attacks, which is the power of the space itself after the portal is formed.

The cornerstone of the portal is the inconspicuous purple crystals at the edge of the portal, which are crystals made of magic, and the magic of the portal passes through these crystals before forming the portal.

In other words, as long as the purple crystal can affect the portal and cause the portal to be unstable, the portal will collapse, and considering the portal's own defenses, the person who can also affect the spatial ability of the space is the best candidate to destroy the portal.
