After saying that, before Barrick and the others could react to the meaning of his words, Uther suddenly raised his hand and raised his staff towards the undead lords in front of him.

A layer of dark blue death suddenly erupted on the tip of the staff, dyeing the entire hall of the Audience with a layer of blue light, and an extreme chill spread.

"You ......" Barrick and the others just said a word with a sudden change in their faces, and they were hit by the faint blue cold light, and everyone's movements couldn't help but fall into stiffness, as if they were frozen.

But after all, the strength of these undead lords is not weak, even if it is only a soul thought incarnation here, and they can't exert 100% of their strength, they will not be directly imprisoned by Uther's casual ice spell and become completely immobile.

"Bastard!"

All the undead lords burst out all the power in their avatars at this moment, and the terrifying death aura even burst the air, shaking the four walls of the floor of the Hall of Hearing to the point of cracks.

But just when the undead lords wanted to make more moves, the ground, ceiling, and four walls of the Hall of Insight suddenly lit up with dense spell formations, and more faint blue light filled every corner of the entire Hall of Vision, and there was also a cold air emerging from under the floor, like a fountain, it happened to burst out from under the feet of dozens of undead lords, engulfing them in an instant.

After a few breaths, when the cold stopped erupting, the center of the Hall of Insight had been occupied by a huge translucent blue ice crystal, and the dozens of undead lords were too like insects frozen in amber, and their expressions mixed with horror and anger were vividly frozen in the moment when the emotions erupted.

"Truly...... Do you think a lich mage's abode would have been unpre-programmed with a spell trap?" Uther smiled at the work of art in front of him, then shook his head regretfully and sighed in a low voice.

"It's a pity that such a rare masterpiece of ice crystal art can't be preserved for a long time. ”

Click, click...... Only a crisp crackling sound could be heard, followed by Uther's sigh in the Hall of Hearing.

After a few seconds of silence, the huge ice crystals that trapped dozens of undead lords began to emerge one after another, and the speed of the cracks spread faster and faster, and gradually, the entire ice crystal faintly trembled.

Obviously, even such an ice crystal still can't completely trap those undead lords inside, even if this is a high-level spell released by Uther with the help of the magic circle engraved in the ancient castle, and the power has the increase of the local formation, it still can't completely seal these undead lords in one go.

There is no way, although these undead lords are only soul thoughts incarnation, and their strength is not as good as the main body, but the number is too much.

If it were only a few, or even a dozen, Uther would be able to directly seal them completely with a single ice spell, but now there are forty or fifty undead lords present, and the power that they have combined to explode in a short period of time is already qualified for Uther to pay a little attention to it.

Seeing that the seal of the ice crystal was about to collapse, Uther was still very calm, because there was no need for it to give special orders, and the more than ten high-ranking death knights guarding the hall of the meeting had already surrounded and launched a charge towards the undead lords in the ice crystal.

When they rushed in front of the undead lords, the pressure on the entire ice crystal also reached the limit, and after a bang, it directly exploded into countless broken ice and shot out in all directions.

Some of the ice splintered directly hit the oncoming Death Knights, but they were firmly blocked by their heavy black armor, and the impact on the armor caused no other damage than a clanging crunch and shattering into finer ice particles, and it didn't even slow the Death Knights' charge even a bit.

Although the undead lords were frozen in ice, their own thinking consciousness was still awake, and they could also sense the situation in the outside world through the ice crystals, so they naturally noticed the approach of the death knights for a long time.

Under normal circumstances, even if these undead lords were only soul incarnates, their individual average strength would still be stronger than that of this group of death knights.

But now, in order to break free from the seal of the ice crystal as soon as possible, the undead lords have just used all their strength to carry out an explosion.

The undead lords who had just erupted with all their might would inevitably decline in their state in the short period of time after that, and in order to quickly break free from the seal of the ice crystal, they actually did not pay any price.

The ice spell that Uther cast with the help of the amplification of the spell circle engraved in the castle was not so easy to bear. Even the deities of these undead lords have to deal with this spell seriously, let alone just their soul incarnation, especially when they are attacked by sneak attacks and have no intentions.

In the short few seconds that this group of undead lords were sealed by the ice crystals just now, they had actually been severely eroded by the ice energy, although this erosion was no longer fatal after being distributed to dozens of people, and it could not even directly seriously injure them, but it was enough to attach a layer of debuffs called 'frostbite' and 'slowdown' to them in the next period of time.

The limbs were stiff, and the energy operation state in the body was also infected and hindered by the power of ice, and it was no longer possible to control it easily.

Unless these ice powers that invaded the body can be eliminated immediately, otherwise, the incarnations of the undead lords at this moment can exert half of their strength.

On the contrary, the Death Knights were not only in good condition, but even Uther intimately cast a group buff spell, adding an extra layer of ice energy to the Death Knights' broadsword that could reach the level of legal concepts, making their combat power directly increase by a large margin.

And the Death Knights, regardless of the state of this group of enemies in front of them, did not have the slightest sense of glory and shame to take advantage of the danger, and faithfully carried out the orders given by Uther, directly brandished their big swords and began to slaughter the incarnations of these undead lords with great efficiency.

When the incarnations of the undead lord finally came to their senses, dispelled the power of ice in their bodies and sorted out the power in their bodies, there were only a dozen incarnations of the undead lords who could still stand.

In just about ten seconds, they were directly reduced by half of their personnel under the siege of the Death Knights!
