This man is none other than El Ro.

Bird and Mia saw that Erno was covered in blood and hung everywhere, as if he had just experienced a great battle.

"What's going on?" Bird looked at Elro's state in amazement, such a wolf Bèi Elro, the last time he saw it was when the red-robed wizard attacked.

"Let's go back and talk about it" Erro's attention was not focused on Bird at this time, but in the puddle in front of him, the wizards who had kept the circle running.

"These are the apprentices of the Rainbow Oss Academy?", Bird glanced at Elro in surprise, it seemed that El Ro should have something to do with the Rainbow Oss Academy now.

"What are you going to do with these people?" asked El Ro in a low voice.

"Of course, this formation is broken, and then the strength of the Rainbow Oss Academy is consumed as much as possible."

"Let's do it now, Naos had just returned to the academy when I first came over, and if I waited, it would probably be too late" Erro said at this time.

Bird stared at Erro, then at the recovery of the crowd, nodded and asked, "How are you?" "Yes" "Okay, up"

Several wizards from the Rainbow Oss Academy were following Oss's orders at this time, maintaining the operation of this formation one by one in order.

That's when the rotation comes in.

One person stood up from the front of the formation, and suddenly the whole person softened weakly, and the person behind him hurriedly supported him and let him slowly stand firm.

"It seems that the foundation has been damaged" The one who was about to be replaced couldn't help but shake his head as he looked at the wizard who had retreated and was already weak.

"Talk less, do more" One of the guards standing next to him scolded the man, then pushed him twice, telling him to hurry up and not let the water in this puddle flow backwards.

That person didn't dare to say much at this time, and hurriedly put out mana to maintain the operation of this formation.

"Why is there a fire on the other side?" The man had just sat down and saw the fire flashing on the other side, although his hand did not stop outputting mana, but he looked at the fire on the opposite side curiously, and he didn't know what it was.

The firelight became a little bigger, and the man suddenly saw what was in front of him clearly, "That's a series of fireballs", the man hurriedly cut off the magic power in his hand, and hurriedly rolled back with a crawl.

At this moment, dozens of fireballs suddenly appeared in front of everyone's eyes, only to hear a few 'bang bang' sounds, countless fires flashed, and everyone quickly squinted their eyes to prevent this firelight from stinging their eyes.

The trio centaur wizards were assigned by Bird to deal with the surrounding guards, as these centaurs had just recovered much mana, but it was enough to deal with these ordinary guards.

The target of Bird and the other three was the several wizards who maintained the operation of the circle, and the three of them fired several fireballs in succession, and then jumped up to prepare to attack.

But just when the fireballs were about to hit the wizards. A curtain of water appeared in front of those wizards, and it actually blocked the fireballs one by one alive without the slightest trace of damage.

Bird was dumbfounded, he hadn't had such a step in his plan. But now we have to move on and see if this light curtain can be broken.

The wizard who had just been rolling around and crawling couldn't help but breathe a sigh of relief when he saw several fireballs under the water curtain at this time, and he was glad that the dean had attached such a small magic circle when he built this magic circle.

"Continue to attack the water curtain," Elro said at this point, it seems that Erro has found a solution to this water curtain.

Bird Mou threw several fireballs and cutting spells towards the light curtain with all his might, and at this time, on the periphery of the puddle, the centaurs killed the guards on the periphery one by one like cat and mouse, and the screams were endless, obviously these centaurs were venting their own experience and dissatisfaction just now, and by the way, they were testing their magic Willy.

The wizards in this water curtain had already been awakened by countless roars at this time, and seeing the tragic scene outside the light curtain, some people were full of anger and tried to come out of the water curtain to fight against Bird and others, but they were helpless because of the lack of mana in their bodies.

"Everyone, rest assured, the dean is on his way back at this time" Someone seemed to have contacted Oss, so he began to comfort the panicked people in the water curtain.

"The dean said that as long as this water curtain is not broken, that person can't do anything about us"

"The water curtain is going to be gone!" someone in the crowd suddenly shouted, only to see that the water curtain turned from dark blue to a thin layer of white under the impact of Bird and others.

"Hurry, come on, continue to maintain the operation of the formation," the wizard who had fled in a hurry before hurriedly stepped forward.

However, his mana was too little, and the running water curtain could not withstand the consumption of the three of Bird, and after a while, he saw that the man's face was pale, and then another person with a little mana recovery continued to give it to the top.

But Bird and the others couldn't afford to be consumed, and Naos might come back when.

"The core of this formation should be in the middle of there," Bird pointed to a whirlpool that appeared in the puddle at this moment.

At this time, the group of wizards were running the circle alternately, and saw that the water column no longer continued to rise from the huge pit, but a whirlpool appeared, and the water was constantly flowing down.

Seeing that the light curtain deepened and turned blue again, Bird gritted his teeth and said, "I'll go down and have a look." At this time, the scene on the water must have Erro, who is a formal wizard different from Bird and Mia, and his magic power, willy, and recovery are far superior to those of Bird.

And I don't know when Oss will come, so I have to hold the scene on the water, so that I can respond to all changes with the same thing, and at the same time, I can consume those wizards, so that the water of this puddle does not flow out as much as possible.

As for Mia, Bird didn't want her to risk going into the puddle, because he didn't know what would lie beneath the puddle.

Moreover, if Bird and the others give up destroying this formation now, with the speed at which water continues to bubble in this puddle, Bird doesn't know what this forest will become in the end.

The decision was made, and Bird fell into the puddle with a 'poof'.

Everyone in the water curtain thought that Bird had run out of mana and fell, and they all immediately laughed, and shouted loudly, "If you don't have this strength, you will honestly wait for our Dean Oss, maybe the dean will be happy to let you join the academy", the voice in the water curtain suddenly laughed even more.

And Erro and Mia didn't speak at this time, but just accelerated the casting speed, so that the formation took less time to run, so that Bird could enter the center of the formation smoothly.
