Nacien was full of curiosity about the black sword in Twilight's hand at this time, and at this moment, he wanted to teleport to the young man immediately, kill him and get the black sword in his hand, but then he thought about it, he had just summoned such a large number of demon spiders through the demon insect array, and he had already consumed a considerable amount of his magic power. Although he was confident enough in his own strength, he could easily kill Twilight and them, and get the black sword in Twilight's hand.

But if you are not afraid of 10,000, you are afraid of what happens, and you back then, it was because you were too confident in yourself that you would be killed by others in the end, so this time, if these people work together, even if you don't kill him, he may lose a layer of skin, so he still decided to restore his magic power to almost the same, and then go to their side, anyway, there are those demon spiders, which should consume a lot of their energy, and if the demon spiders kill them, it is naturally the best.

However, after thinking about it, he decided to regain some of his magic here, and then slaughtered the men and captured the black sword.

At this time, Twilight, Tian Weiwei, Zi Mingyue, Avrila and Elthea were still killing those demon spiders, but in the face of the powerful magic and the number of human-faced demon spiders, they also began to be a little powerless, although there were also some students who ran out of the classroom and helped them deal with these monsters, but it was still only a drop in the bucket.

"There are too many of them, damn ......" Although relying on Twilight and a few people, they killed a lot of demon spiders that entered the academy, but in the face of the continuous flow of demon spiders that were teleported in, at this moment Avrila and Elsia were already a little tired.

At this time, the teleportation of the magic array had stopped, and now even the demon spiders that were destroyed by Twilight and the students added up to only about two thousand, and at this time, there were at least seven thousand demon spiders in front of them. At this time, these demon spiders suddenly stopped moving, and then, from their mouths, they all spit out silk threads towards the top of the people at the same time. And the silk threads spit out from the mouth of the demon spider kept scattering, wrapping these demon spiders, and slowly forming cocoons one by one.

At this time, Nacien, who was watching this scene through visual sharing, showed a smile instead, he didn't expect that these facial demon spiders would feather at the same time at this time.

Human-faced demon spiders have a characteristic, that is, when their magic is so strong that they can no longer bear it, they will wrap their bodies first by spinning silk to form something similar to a cocoon, and in that cocoon, they will adapt to this powerful magic by changing the form of their bodies, and after completely changing their body form, their own magic will be improved again, so that they can complete this task without making a move.

Twilight Kui and they can also feel at this time, from those cocoons, they can feel extremely powerful magic, although Avrila and Elthea both tried to destroy those cocoons, but these cocoons are extremely hard, their magic, can not destroy those cocoons at all, Twilight Kui used the black sword to destroy, and also failed.

And at this time, those cocoons began to produce cracks one after another, and from the cracks of those cocoons, powerful magic power was emanated, and then, the cocoons burst one after another, and from those bursting cocoons, one after another three-headed monsters came out.

The monsters that emerged from the cocoon had 3 heads like the demon spiders, but at this time, the 3 heads all had human faces, and their bodies were no longer the bodies of spiders. The hands on the body have also become closer to the appearance of humans, and the sharp claws on the hands have become sharper at this time, and at first glance, they look like sharp blades.

The magic power emanating from these monsters was even more powerful than when they were spiders just now, and Tian Weiwei, Zi Mingyue, Avrila and Elthea even broke out in a cold sweat, their feet trembled uncontrollably, and it was extremely difficult to even stand.

And even Twilight Kui felt a trace of danger at this moment, the academy at this time had been completely occupied by these monsters, no matter what, no matter how strong his strength was, he couldn't defeat such a large army of monsters alone.

At this time, these monsters finally began to move, and the monster closest to Twilight Kui attacked Twilight Kui with its scorpion-like tail at this time.

Although Twilight Kui escaped the blow by jumping away, but this monster relied on the claws that could already match the blade, and launched another attack on Twilight, and this time, Twilight Kui hurriedly protected his chest with the black sword, blocking this blow, and then, one of them flipped back to the ground, and at this time, the monster had moved to Twilight's side again, and the blade-like claws swung down at Twilight Kui again.

Although Twilight Kui once again blocked this attack with a black sword, at this time his hand holding this sword began to feel a little numb, and what was even worse was that this group of monsters had also begun to scatter at this time, and among them, some of the monsters had even come to Tian Weiwei's side.

"Damn, damned, damned, damn spider."

Twilight didn't hold back any longer, and hurriedly summoned a shadow warrior.

In addition to summoning the shadow warrior, Twilight Kui also shouted hoarsely to the sky, and the black sword in his hand, the black and gold decoration on the hilt at this moment, actually began to show a flickering light, and then, the black sword in Lu's hand actually began to change its appearance.

The original black sword blade became even darker at this time, and the sharp blade also became sharper at this moment, and even reflected the light on the sword body, and the pattern of the black gold decorated sword hilt at this time also slowly changed, and then, the decorative pattern actually began to climb up the sword body, and then, slowly integrated into the sword body, and it looked as if the pattern appeared on the sword body.

The black sword, which had changed its appearance, returned to Twilight's hand, and he immediately raised the sword aloft...... Then...... Swing it down!

The sword swung down, as if connecting the surrounding time and space...... Everything was cut off by this sword! Even the space around him was cut off, and then restored in just a second.

An extremely powerful terrifying force enveloped the entire academy in an instant, and this blow actually wiped out many monsters in the entire academy in an instant! And even the students in the academy felt a powerful force sweep through their bodies.

In fact, about this black sword, Twilight Kui has studied it many times.

In the end, he discovered that there were many unknown powers swimming in this black sword, and I am afraid that this black sword was actually an extremely terrifying killing weapon! If not, why is there such a terrible power now?

"This sword...... What is it exactly? Twilight looked at the scene in front of her and uttered the words from the depths of her throat.
