At this time, the spell that the old mage was about to release had already taken shape, it was the three-ring spell ice spear, but with the blessing of the magic circle, the ice spear that was originally a child's wrist was now as thick as an adult's thigh, and the cold air emitted was also amazing.

With a wave of the old mage's hand, the thick ice spear flew down the staircase.

Under the amplification of the circle and the powerful mental power of the old mage, the Ice Spear not only increased its power, but also flexibly turned and flew down the spiral staircase.

To be honest, the ice spear can turn this strange painting style Ye Qing felt weird, thinking that he was wrong, but the fact is that it happened, he really turned around and flew down the stairs, and he also shocked his glasses... If only he had glasses.

The ice spear entered the back of the stairs, and Ye Qing couldn't see the situation behind it, only heard a bang, and an angry roar, and then a large amount of cold gas erupted from the staircase, which should be the cold air emitted by the explosion of the ice spear that was shot.

An ice spear can't help the Dark Overseer, of course, but what if it's continuous?

With the blessing of the magic circle, the spells cast by the old mage were almost uninterrupted, as if they were instantaneous, and the thick ice spears were condensed and shot downward.

Especially when the entire staircase was demolished by the Dark Overseer, the thick pillars fell, and a large hole appeared in the original staircase where the boss could be seen, the spell cast was faster, and almost a second was an ice spear condensed and formed.

Without stairs to block it, Master Amanda doesn't need to control the spell corner, he can save a lot of energy and concentrate on casting spells, and the frequency of strikes has increased several times, and more than a dozen ice spears shot down in one breath, knocking back the Dark Overseer on the spot, and falling directly to the next floor.

Fighting hard with a mage with the blessing of the magic circle, this is purely death, as long as the old mage has made up his mind, the tower is seriously damaged, and he can easily drown the boss with spells.

In fact, if the old mage activated the magic circle on the tower at the beginning, he could directly knock the Dark Overseer down, but he was reluctant to destroy the tower at first.

Although the Dark Overseer has a strong physique and super vitality, it can't withstand this kind of non-stop spell bombardment, you must know that the lethality of this random strengthened ice spear is more than a thousand, and it will not last long if it is continuously bombarded.

The Dark Overseer was pinned to the eighth floor with a blast of ice spears once in a second, covering it with a flood of cold air that nearly froze it in place.

Ice spells are like this, when ice spells are used so uninterruptedly, the cold will accumulate, and when it accumulates to a certain point, the cold can affect creatures with strong physiques, even if they were previously strong enough to be exempt from the cold slowdown effect, they will be affected by the cold under the continuous accumulation.

Now this is the case with the Dark Overseer, a large number of ice spears close to the four rings have been bombarded on its body, a large amount of cold air has accumulated, and if it can already reduce its speed significantly, some places where its body meets the stone face have begun to condense thin layers of ice.

If this continues, there is a possibility that the accumulated cold will forcibly freeze the boss in place.

Seeing that the teacher was so powerful, Ye Qing was very excited, which meant that he could be so powerful in the future, if he could muster enough resources, he could also build a mage tower, and it would be great at that time.

Every mage is qualified to build a mage tower, and if he can switch to the mage profession, he will have this qualification.

A mage with a mage tower and a mage without a mage tower are completely different concepts, and this is a building that is even better than the current circle of Mage Amanda.

In fact, the circle of Teacher Amanda is the prototype of the Mage Tower, but the level of this dungeon is too low, and there are not enough resources to build the Mage Tower, if this is a Bronze-level dungeon, there is a possibility that the Mage Tower will appear.

Think that a weakened version of the circle has such power, if it's a complete mage tower, what is the concept?

Watching the old mage condense one ice spear after another, beating the previously invincible Dark Overseer to the brink, Ye Qing's eyes moved slightly.

A one-star boss-level boss head, this is very tempting, he dares to guarantee that if he kills it, he will definitely be able to burst out a yellow rare equipment, which is extremely tempting for him, you must know that even the infinite magic ball is only a yellow grade equipment at this stage.

It's just that he didn't have a chance to start, although he was beaten like a dog by the teacher, it doesn't mean how weak this guy is, if the teacher stops attacking, it won't be long before this guy can recover some of his strength.

Of course, this is not the reason why he doesn't do it, the main reason why he doesn't do it is because he can't do it.

He was next to the old mage, in the circle shroud range, where he couldn't use any spells, and if he wanted to do it, he had to leave the circle range, but out of the circle range, he didn't dare to guarantee that the boss would not kill him.

Although he was beaten to the point of death, it didn't take much effort for the Dark Overseer to deal with him, and he could tear him in half with a single claw.

Therefore, although he was very envious of a BOSS head, Ye Qing still put away his greed sensibly, dripping blood in his heart, and silently watched the teacher beat the BOSS into a dog.

If all goes well, it won't take long for the Dark Overseer to turn into a corpse.

However, the world is full of all kinds of accidents, and at this time, two figures appeared from the skylight outside the tower, it was Yu Xinghai, the tutor of the elite class who led the team this time, and an elite class student.

The two of them actually climbed up along the tower from the outside, and touched in when the old mage used all his strength to mobilize the energy of the magic circle to shrink, and the aura disappeared from the skylight.

The strange noise alarmed Ye Qing, he turned around and immediately saw Yu Xinghai, and immediately said:

"You are a tutor, how can you participate in the student's plot? You are violating the rules set by the school. ”

Yu Xinghai didn't talk to him at all, his eyes glanced at him, and he put it directly on the old mage, and immediately took it out of his pocket, took out a scroll and tore it open, and immediately an illusory female figure flew out of it, and her arms opened her mouth to let out a silent cry.

"Banshee Howl!"

Ye Qing was shocked inexplicably.

But soon he reacted:

"No, it's a ghost scream, what do you want to do?"

Yu Xinghai didn't speak, but the elite student on the side replied with a sneer:

"Of course it's to kill the boss!"

The ghost scream is not as famous as the Banshee's Howl, but it doesn't mean that the power will be weak, the effect of both spells is the same, emitting a terrible scream, so that all the targets who hear it need to undergo a will immunity test, and there is no effect if the test passes, if the test is not passed, there is only one consequence, that is, death.
