Seeing that this huge obsidian level was about to be dragged from the air to the ground, the unexpected happened again!

"Hiss......"

The two holes in the head of the obsidian class suddenly emitted a thick white gas, and a cloud of turbid strong acid dispersed and fell to the ground like raindrops, and the corrosive liquid that was smashed towards Mu Fengye was mostly blocked by Rodt's obsidian, but Claude's team was not so lucky.

"Sioske, get out of the way!" Claude dodged the liquids at Claude's speed, and Ceciriel had been hiding in the distance since the beginning of the war, out of the range of acid rain.

"Whew-"

The hot acid engulfed the helpless Siossk, and everyone began to panic when they watched him be burned to bones from head to toe in an instant.

"Save me ......" As he was dying, Siosk relied on his last instinct to ask for help from the others, and he stretched out his acid-stained hand bones and grabbed the nearest Federmont!

"Uhhh

"Fedmund, cut off that hand!" Claude knew that if Fedmund couldn't bear it, the acid would keep on swallowing until he was swallowed to bones like Sioske.

"Uh-uh...... Uh-ah, I can't!" Federmont's right hand trembled and clenched the dagger, hesitating but still not daring to move, even though the arm had been reduced to bones, "Don't...... I don't want to die!"

"It's useless. Claude shook his head and gave up Federmon's life, the acid ran down his shoulder to his chest, he was no longer saved, if he had cut off that arm decisively, he might not have died, "Signas, I Ministry, are you two okay?"

"It's fine. ”

The Obsidian class seems to have regained some of its strength, and quite a few of them disconnected from Obsidian when Siosque and Fedmund died, causing the memory to be unable to continue suppressing its power.

"Oh no, that guy is fighting back. Gao Zhi looked up at the obsidian-level giant beasts in the air, the limbs that grew around the body were shaking wildly, and the silver carapace secreted a large amount of acid, quickly corroding the obsidian of Rozter and Mu Fengye, and it didn't take long for the obsidian rope to break in the middle.

"Shh

The obsidian-level roared angrily, and a black circle of light seemed to appear above its head, and countless spikes surged out of it, shooting quickly into the ground!

"Spread out, everyone, and hide in the forest!"

"Whoosh Whoosh ......"

Rozt unfurled his obsidian shield to cover the students' retreat into the nearby forest, the spikes soaked in strong acid, and even Rozt's shield began to corrode.

"Cut, trouble guy. ”

As a last resort, Rozter had to gather more obsidian crystals around him to repair the weak points on the shield, once the shield was penetrated, the compressed obsidian crystals would immediately disperse, and the spikes of the rainstorm would shoot everyone!

"Shhh

"Click......

"Oops. The defective obsidian didn't have time to replace the new crystals, Rozter had done his best, but he still couldn't prevent the fact that the shield was pierced, looking at the spikes in the sky after the obsidian collapsed, he was unwilling to condense more obsidian crystals to resist the attack, "Damn......"

"Whoosh-"

The moment the shield was propped up, two spikes shot straight at Rozt on the ground through the hole!

"How could I die here......"

"Huh!"

When all thoughts were lost, a sharp sword slashed towards the spike, instantly cutting it in two, and the other spike was blocked by Gao Zhi even if he held up the shield, and the two worked together to save one of Rozt!

"You ......"

"Excuse me for a while, Sakuruma has already figured out a way. Mu Fengye bypassed the obsidian shield and looked carefully at the obsidian-level monster in the air, the black aperture above its head still existed, that thing was equivalent to a small wormhole, as long as it was destroyed, these spikes would not continue to fire.

"Sakura, as you think, what should I do next?" After some reconnaissance, Mu Fengye returned to the forest and told Sakurama everything he saw.

"Sirina, can you throw your spell to that height?" Sakuruma asked, turning her head.

Serina frowned, and said firmly: "If you can't do it, you have to work hard, this is a matter of everyone's life!"

"Very good, Gao Zhi, after Rozt withdraws the shield, protect the Sirina behind you, that side is outside the attack range of the obsidian level, Mu Feng, do you still have the power to condense the obsidian?" Before Sakurama could analyze the battle situation, she had already asked the others to move to the other side of the forest.

"Wait, since it's outside the range of the obsidian-level attack, why don't we all go over?" Mu Fengye asked.

"You must leave behind the people who lure the enemy, the obsidian level can see your ability, if you evacuate all of them, you will definitely be discovered, although they are monsters in this world, but they still have a certain ability to detect, only here is the most suitable to launch a raid. Sakurama explained.

"Well, I see. ”

"Come with me. ”

The battle plan has basically been deployed, Gao Zhi took Silina to the back of Rozte, with Rozt's ability to protect himself at the moment of removing the shield, the key to this battle is whether Sirina's spell can successfully bombard the wormhole above the obsidian level after Rozte removed the obsidian shield.

"Gao Zhi, are you ready?" heard Sakura's voice in his ears, and Gao Zhi set up a black shield and half-crouched behind.

"Rotzt!"

Upon receiving the signal, Rozter immediately shrunk the obsidian shield and quickly retreated to the forest, using the dense trunks of the trees to fend off the spikes in the air.

"Whoosh-whoosh-"

In the blink of an eye, the ground that was extremely empty just now was suddenly filled with black spikes, and Sirina's heart beat to the extreme, carefully peeking her head out from behind Gao Zhi, and forcefully throwing the charm on her waist into the wormhole in the air.

"Boom !!"

The spell was shot through by dense spikes just a few meters after it was thrown, and it detonated early, which is also a point that Sakurama overlooked, and now it is almost impossible to retreat, and the next thing is up to Sirina to deal with it.

"Hmm......" Gao Zhi could feel a huge impact in front of him, and his body was constantly retreating, and the ground under his feet was almost stepped out of the pit, but this momentum still continued to strike! "Miss, hurry!"

Serina grabbed all the charms and threw them into the sky!

Different spells had different effects, with layers upon layers of thick ice blocking most of the spikes falling from the sky, while also providing perfect cover for the explosive spells in the rear. Countless ice flowers burst through the air, and eventually several black explosion spells were sent into the wormhole above the obsidian class.

"Boom-"

The blasting sound was incessant, and after an obsidian scream, the spikes stopped firing.

"Mu Feng, it's now!"

"Drink!"

A black hand grasped the obsidian level that Yu cut stabbed from the ground to the air, and the sharp blade was unstoppably inserted into the obsidian-level armor, leaving a lot of bloody cuts on the body with the swing of the big hand!

"Yes! Well done!" Gao Zhi excitedly put away his obsidian at the sight, surrounded by spikes soaked in strong acid, and had to be very careful to get out of here.

"Hey, Gao Zhi, how are we going to get out?" Seeing that Mu Fengye over there had already controlled the situation, Serina hurriedly looked for a way to leave, but the spikes inserted here were too dense to get their feet down.

"Miss, come up. Gao Zhi suddenly picked up Sirina, and she trembled violently in fright.

"What are you doing?!"

"If I accidentally step on those things, at least you can step on my corpse and get out. ”

"Gao Zhi, you ......" Serina suddenly felt her nose sour, and tears couldn't help but roll in her eyes.

"There's no time, maybe that guy has the next round of attacks, and standing here will be a living target. Gao Zhi was about to step into the pile of spikes, but his front foot was just about to touch the acid, but he was picked up by an invisible palm and sent to the safety of the forest before stopping.

"Rozt?" Gao Zhi looked at Rozt behind the tree in surprise and said in surprise, "Why do you want to save us?"

"I don't want to owe anyone a favor, there won't be a second time. "Rozt's stamina had been drained, and everyone seemed to have done their part to defeat the obsidian in the air, and although they had met on the battlefield as enemies before, they were now friends with each other.

"Hurry up and help, it's not good for us to drag on too long. ”

……

"Phew!"

The sword and the silver blade collided I don't know how many times, and it was the first time Takagi had encountered such a strong opponent, it was even more powerful than the obsidian Iroh, and each knife had a purpose, not like it was wielding it indiscriminately.

"Uhhh

The wind blade swept through the Sky Tree, but the Obsidian class once again escaped into the trunk, waiting for Takagi's attack to end before catching him off guard from a strange angle!

The silver blade stabbed out diagonally and slashed towards Takagi's head!

"Ding!"

"As an obsidian-level monster, the strength is not bad. Takagi flicked off the blade and jumped down from the Sky Tree, and when Obsidian thought that Takagi was going to flee and pursue, his left hand suddenly buckled the spiral pattern of the Sky Tree, and he twisted behind Obsidian!

"Die in peace. ”

The knife stabbed hard through the back of the obsidian-level neck, but as soon as he stabbed half a centimeter, Takagi sensed that something was wrong, and the stab didn't feel any real at all, as if it had directly passed through the obsidian-level body!

"Damn ......"

Obsidian dodged the deadly threat and turned around and punched Takagi in the chest, smashing him off the tree!
