Rocks kept falling overhead, explosions were still heard around them, and the entire interior of the Nexus was in chaos.

Su Chen nervously rushed to Teresta's residence, but he didn't see her, which made his worries even more serious.

However, when he arrived at the site of the explosion, he was slightly relieved to see a group of High Elf mages desperately resisting the attack of a large number of blue dragonmen, led by a tower dressed in blue mage robes.

The blue dragonmen were so angry at the High Elves' betrayal and destruction that they would rather abandon their defenses against the entrance to the Nexus than run to kill them.

It's just that the interior of this hub is now filled with a large amount of arcane energy, and the magic power of the mages is almost endless, and all kinds of arcane missiles are wildly unleashed towards those dragonmen like rain.

When Su Chen appeared with a large number of paladins and dragonmen of the Dragon Sleep Alliance, the battle quickly turned in their favor, and the troops of the Blue Dragon Legion quickly collapsed under the front and rear attacks.

Of course, the collapse of the Blue Dragon Legion's troops so quickly should also have a lot to do with the chaos of the Demon Hub at the moment, and with the internal destruction of the Demon Hub, these Blue Dragon Legion's troops have no intention of fighting at all.

"You guys have done too much damage this time, the demon pivot is estimated to collapse soon, everyone get out of here quickly." Su Chen hurriedly said to Teresta.

"I didn't expect it to be so serious, we just blew up a section of arcane energy transmission pipe, but we didn't expect it to cause a series of explosions, it is estimated that we accidentally blew up a more important magic network node." Teresta smiled wryly and looked overhead, apparently she herself had not expected the damage to be so severe.

Su Chen followed her gaze and looked up, only to see that a huge collapse crack had appeared above, and he could see that the huge arcane energy was surging upwards like a tide.

"It should be the magic ring from here...... Su Chen thought secretly, and at the same time, he couldn't help but worry about whether the attack on the magic ring by Crassus and the others could save Chromie.

At this moment, a high-pitched and angry dragon moan suddenly came from above.

"Teresta, you dare to betray the Blue Dragon Legion!"

Immediately, a huge black shadow swooped down from the collapsed crack above, and even completely destroyed many of the already broken buildings along the way, and a large number of stones fell from above, and the arcane energy that had originally escaped upwards was also washed away.

"It's a dragon!" Su Chen was shocked in his heart, he originally thought that this time the battle of the Demon Pivot was very easy to solve due to the internal response of Telesta, but now it seems that the real enemy has just appeared.

The dragon swooped down at a rapid pace and began to retract its wings, and the fierce wind immediately filled every corner, making it almost unsteady to stand.

It was a huge blue dragon, and with its appearance, the already frosty Nexus became even colder, and everyone even found that the soles of their shoes began to freeze together with the ground so quickly that they had to keep moving.

"It's Elegos!" Beside her, Teresta instantly showed a look of horror, and although her power had been elevated to the rank of archmagister within the Nexus, she still had a psychological fear of the dragon.

"Elegos, Guardian of the Web...... Isn't this guy guarding the magic ring? Su Chen couldn't help but be stunned, the giant dragon Elegos was quite trusted by the Blue Dragon King Malygos, and had been guarding the highest part of the magic ring, and now he should be fighting with Crassus and other dragons.

"Celesta you damned elves, you dare to betray the Blue Dragon Legion, I have long known that weak elves cannot be trusted, rather than let you guard the Nexus, it is better to let those constructs come." Elegos roared, and a large gulp of frost breath spewed down from midair, enveloping almost the entire space.

Everyone had to try to dodge immediately, Su Chen had already turned on the anti-magic shield, but the ice crystals that came with the breath hit the armor, and they still kept making a sound like a golden stone.

The armor on some paladins was even dented directly by those ice crystals, and they could barely resist it with the blessing of the power of holy light.

Celesta and other elven mages were also completely suppressed by the dragon, the blue dragon was already extremely talented in magic, and Elegos, as the guardian of the magic net, seemed to have a great ability to manipulate magic, and could even directly control the flow of those magic in the surrounding space.

The strength of Teresta and the others originally came from the Blue Dragon Legion, and now they had no power to fight in front of this blue dragon.

And although the paladins and dragonmen of the Dragon Sleep Alliance brought by Su Chen would not be affected in terms of magic, they would not be able to fight a giant dragon at all due to the difference in strength.

In order to reduce the senseless casualties of his subordinates, Su Chen ordered everyone to retreat on the one hand, but rushed forward with frost in his hand on the other.

According to the analysis of Zhi Brain, the dragon named Elegos is no worse than the black dragon princess Onexia, and he can only fight against it when he uses demon transformation.

However, the time for the demon's transformation was too short, and now it was in the territory of the Blue Dragon Legion in this demon hub, and once the time for the demon's transformation came, he would be extremely vulnerable to danger when he fell into weakness.

Therefore, Su Chen decided to use his magic immunity, which he had never used in front of others, to fight against him.

"Damn humans, you actually did it to the noble blue dragon, I want to make all of you into ice sculptures, and make you the best ornament of the Demon Hub!" Elegos roared under his breath and spewed a breath of ice dragon breath at Su Chen, his huge dragon eyes full of contempt and mockery for Su Chen.

Su Chen once again turned on the Death Knight's anti-magic shield and white bone shield, but these two skills did not have any substantial defensive effect under the dragon's attack, and he was completely relying on his strong physique to resist.

However, these skills also confused the dragon in front of him, causing it to let Su Chen approach unsuspectingly.

It wasn't until Su Chen jumped up and stabbed him in the abdomen that the blue dragon let out a huge roar containing pain and horror.

The Frost Sorrow was still sharp, and with a single sword, it pierced the thick dragon scales and sank into the hilt.

It's a pity that the current length of Frost Sorrow is still too short for a dragon tens of meters long, and even if a sword pierces it, it is still difficult to inflict fatal damage on it.

In the next moment, Su Chen had been completely annihilated by all kinds of magic, and all he could see was endless flames and frost in his eyes.

"How dare you hurt me! I'll make you turn to ashes in magic, I'll ......" The dragon's roar came to an abrupt halt, and it turned into a huge scream. (To be continued.) )
