What should I do?Couffren's gaze swept over everyone's faces one by one, and found that in addition to panic, there was a blank expression, although Rebecca's face looked extremely calm, but judging from the occasional flicker in her eyes, this magician who had recovered a lot of magical strength actually did not have a very good way to deal with the problem in front of him.

As for the other people, who are already intellectually worried, they can't count on it. Maybe the guy who was pretending to be dizzy could provide something effective? Coughren secretly regretted that he should have agreed with Alfie about a way to deliver the message so that he could ask Alfie what he was planning.

It's a pity that when they found out that they were facing the Sorens Demon Grass, which was particularly sensitive to divine magic, Celent hurriedly removed the sacred barrier, and the concealment potion mixed in it naturally lost its effect, which made Coughren not dare to talk to Alfie rashly, in case Cross, who was secretly spying, found any flaws.

Just when Coughren was at a loss, Celent suddenly made a move. He walked over to the cage where Iero was imprisoned, and carefully examined the iron fence in front of him.

"Anyway, let's get Mr. Arrow out first. Sellant explained in a self-to-own voice.

"Be careful, paladin. Those iron fences are self-defending, so beware of them bouncing off the Sorens Magic Grass. Zambit, who has suffered a lot, reminded.

"How do you know if you don't try it?, and although those Sorens magic grass seems to be far away from those cages right now, when it crawls all over the hallway, it will sooner or later spread into the cage, and we need to get him out as soon as possible. Mr. Ayrault can now be said to be powerless. Celent said, flipped his hand and revealed a vial of tan potion.

"It's ...... Corrosive Elixir?" Coughren blurted out as he looked at the familiar color emanating from the vial.

"I guess so. Silent replied without confidence. This is what Alfie took out of the spatial ring and stuffed it into his hand just now, and he is not sure what the specific potion is Serent.

"Do you want to corrode these iron fences with corrosive agents? That's so clever!" Zambit had seen the power of corrosive potions with his own eyes. In the second level, a vial of corrosive potion dissolved in Barnett's bathtub corroded a passage through the frozen pool.

"First of all, I have to make sure that these iron fences are not treated with preservatives. Although the rust on the iron fence was unmistakably unmistakable and unequivocal, Celent did not take it lightly.

In his hand, another dropper made of crystal appeared, the only substance that the corrosive agent claimed to be able to corrode everything could not corrode.

Sellent carefully opened the cap of the corrosive potion, and a pungent smell that everyone was familiar with emanated, which was the purest corrosive potion.

Syrent used a dropper to draw a potion, then closed the cap and gently leaned over to the cage where Iero was imprisoned, dropping the dropper onto the bottom of one of the iron rods in the iron bar.

Everyone held their breath and stared nervously at the potion, whether they could successfully rescue Eero depends on whether the corrosive potion is effective against the iron fence. As for the imminent threat from the Sorens Magic Grass, it was temporarily left behind by everyone. At least for now, the monster seemed to be afraid of Rebecca's defenses against the nets of fire, and the spreading black vines temporarily bypassed the nets of fire that enveloped everyone.

After the corrosive agent dripped on the arm-thick iron fence, the iron rod burst out a small arc of electricity, as if trying to bounce the approaching corrosive agent away, but the unique conductivity of the liquid caused the self-protective arc emitted by the iron fence to twist and pass through the drop of corrosive agent, and did not play its due protective role.

After the drop of corrosive agent passed through the self-protection of the iron fence "unharmed", it dripped on the iron rod, making a sizzling sound, and a wisp of green smoke came out of the iron rod, and at the same time, a special corroded pungent smell came into everyone's noses.

Everyone didn't care about the discomfort to their lungs after inhaling the pungent smell, they were more concerned about the effect of the corrosive agent,—— the effect was very obvious, the bottom of the iron rod, the place where it came into contact with the corrosive agent, was quickly corroded into a large hole the thickness of a finger, so it seemed that only two or three drops of the corrosive agent could completely dissolve the iron rod.

"I'm coming, I'm coming!" Zambit, who was eager to save his friend, almost "snatched" the bottle of corrosive potion and crystal dropper from Serent's hand, and began to repeat Serent's action just now, dripping drop after drop of corrosive potion on the iron fence.

"Mr. Zambit, be careful not to drip too much at once. The power of the iron fence to protect itself seems to be related to the size of the thing attacking it. Celent whispered a reminder that this was exactly what Alfie had inferred from his reaction to the iron fence to defend himself after seeing Celrant's movements, and then telepathically told Celrent.

"Don't worry, I'm measured. Zambit said nonchalantly. However, Zambit is still more trustworthy at this time, after all, this troll warrior is extremely desperate, as long as he has seen it, he will be extra careful.

In the process of operation, Zambit found that the iron rod was corroded a little, and the self-protection ability was greatly weakened, and the arc became smaller and smaller, and after the iron rod was completely disconnected from the iron fence, it completely lost its self-protection ability. This discovery boosted Zambit's confidence.

Zambit carefully dripped the corrosive agent on the upper and lower ends of the iron rod, and after the corrosive agent completely corroded the part of the iron rod connected to the iron fence, before the iron rod fell to the ground, the light Shu ape arm grabbed the iron rod that had lost its ability to protect itself, and gently removed it from the iron fence.

One, two, three, each iron on the iron fence was only about ten centimeters apart, and after Zambit used corrosive agents to remove all three of the iron rods next to each other, Celent stopped Zambit from preparing to destroy the fourth iron rod under Alfie's reminder.

"Enough Mr. Zambit, we don't need to waste precious corrosive potions on these iron fences. This was the reason given by Alfie, and Sellant recited it as it was.

"Precious, do you know how many of these potions are hidden in that kid?" Zambit said dissatisfied. He was so angry at these iron fences that he had just suffered a big loss, and he wanted to use corrosive agents to completely destroy them.

......

"Why, these intruders are so disgusting that they dare to destroy the ancestral dungeons of the castle!, but that's fine, you'll soon regret your actions, and are you ready to tremble under the attack of the Saurens Magic Grass?" Cross's sinister laughter echoed through the chamber, and the smug castle steward seemed to ignore the castle master's displeasure.
