"Dan, you continue to attack, Adil immediately rests and recovers!"

"Melissa, you must not leave the team more than three meters, pay attention! Your responsibility is to protect Sophia and them!"

"Sophia and Luna, are you feeling better, and if you can still hold on, try to heal everyone's injuries!"

"Keep back!" and enter that alley, and there will be no enemies on either side of us!"

One order after another was issued, and Caterina slashed away the enemy in front of her with a sword, escorting her companions backwards.

Just ten minutes ago, the protective circle bloomed with its last brilliance, and exploded outward with a powerful impact, shaking the dozens of undead creatures around them into a blur of flesh and blood, and barely had the strength to fight again. And one of the palms of that ancient mummy was also strangely twisted, leaving only the other hand to attack.

However, the number of undead who rushed out of the darkness did not decrease at all, and when they saw that the golden wall of light that had been holding them back finally disappeared, they immediately frantically swarmed up to tear these humans to pieces.

Kaka was rushing over, he had just removed one of the leg bones of Doom, and the tall skeleton warrior stood unsteadily and fell to the ground, although he was still wielding a mace, and the remaining hands and feet were trying to support his huge body to crawl on the ground, but he couldn't keep up with the speed of the alchemist.

But Kaka was also hit - once the mace was swung a little slower, and the left shoulder was slashed by the spikes on the mace, and the blood oozing out had already stained half of his body. However, the alchemist poured a bottle of potion down, rushed under the opponent like no one, punched a big hole in the connection between the two leg bones of Doom's left leg, and then he held the calf bone and pulled outward, destroying the enemy's center of gravity and directly knocking Doom to the ground.

The tall skeletal warrior crashed down, killing a few hapless ghouls by the weight of his body alone, and then more elite ghouls and mummies swarmed him and used his body to "bury" Kaka and an entire left leg of the tier 4 class.

After more than ten seconds, a bulge appeared in the middle of these huddled enemies, and then dozens of undead creatures seemed to be sprayed out, flying into the air before they began to fall, continuously slamming to the ground.

The alchemist stood up from the ground, carrying half a leg bone in his hand, chasing after the "miscellaneous soldiers" who dared to press him to the ground, and for a time this leg bone became his sharpest weapon, beating the nearby undead creatures to broken bones and tendons.

The undead creatures did not feel pain, so whether the calf bones were removed or the bones on their bodies were broken, they would not stop attacking, and the huge mace swept over against the ground with a "buzz", and the alchemy master hurriedly used the bones in his hand to support the ground and dodge this attack.

"Believe it or not, Lao Tzu......" Kaka was halfway through his cruel words, when he suddenly saw that the protective circle he had laid had failed, and the undead creatures were rushing towards those young people in a swarm, his face immediately changed, and he rushed over with a "weapon" more than a meter long.

In the first hundred years, this alchemist almost never worried about the life and death of others other than himself, but he didn't expect that after spending a few months with these young people, he suddenly felt a strange feeling in his heart, as if the future of these children was closely related to himself, and he would rather break his own muscles and bones than see any misfortune between them.

Especially Leon, this "stupid and stupid" human for the alchemist can sometimes make him half angry, but I don't know why, the more this way, the more Kaka invests in the apprentice, at first he still has a long-term investment plan for Leon, but now, especially to Campbell, this thought gradually dissipates from his mind, and he can hardly remember it anymore.

Because in Campbell's Redfield Manor, although there is only a simple temporary workshop in Kaka now, the alchemist actually feels a "home" atmosphere in it, which has not been felt in Ash Town, not in Chaos, and not even in his decades of travel.

So Kaka would rather give up his alchemy research for the sake of their safety, as long as he brought them all back safely, wouldn't his heart be at ease?

"Hold on, I'll be here soon!"

The alchemist rumbled over like a bulldozer, but before he had run ten meters, his body suddenly froze, and immediately raised his leg bones in front of him, and after a sharp beep, the entire white and solid bone turned into hundreds of pieces in his hand, and Kaka took a few steps back, and several shallow blood marks flowed from his nostrils and ear holes.

"I didn't expect there to be an alchemy master of dwarfs, it's really rare!"

The mysterious man's dry voice appeared on the left, and Kaka tilted his head and looked at it coldly, "Don't talk nonsense, a dual professional of a revenant master and an undead summoning master is much rarer than a dwarf alchemy master. ”

"Oh no, we don't need to discuss this, if you're in the mood, join me in watching these humans' expressions of fear before they die," the mystery man smiled, "but I'm afraid you're not too interested." ”

Although Kaka faced the mysterious man with an indifferent attitude, there was a glass bottle hidden in the palm of his hanging right hand, and at the same time, he sighed in his heart, "There is only one bottle of the Sacred Sea left, this potion is indeed the most effective against undead creatures, but the materials are too difficult to obtain!"

Then he flicked his fingers, and the glass bottle tumbled and flew into the distance, exploding near Caterina and them, spreading a rich divine aura.

"Hehe, it's just the battle of the trapped beasts," the mysterious man did not stop the alchemist's movements, and seemed to have no concern for the survival of dozens or hundreds of undead creatures.

Kaka's shirt had already been torn off to arrange the magic circle, so he was naked, with six glass bottles between his fingers, and said with a smile: "How can there be so much nonsense, I have confidence in those young people, not to mention that you think it will be okay to trap my apprentice with a maze technique?"

"Hehe, so if it's not a trapped beast fight, you have to fight it first!"

......

The alchemist seemed to have full confidence in the apprentice, but the apprentice himself was sitting helplessly on the ground in an underground library no more than five hundred meters away.

"Your sister is unscientific......"

Leon couldn't help but mumble as he looked at the empty space around him that had been destroyed by him.

"Isn't the trigger here?" he stood up again, walking around the surrounding wall, lest he miss something.

Still nothing has been found.

Leon went to the secret door again and punched and kicked him, and then returned to the cabinet with his body that was sore from the shock - he couldn't shake the secret door with his strength, which meant that no one could come.

I can only continue to study this cabinet one more time.

"It's over, it's definitely not here," Li Ang grabbed his hair, his heart was simply depressed, "Think about it, too!

"There's no substitute for something like this, right?" Leon crouched in front of the bookcase, looking at the missing spot with a pensive expression, while his hand unconsciously rubbed the cover of one of the books, muttering, "Even if I could replace it with other books, I didn't, didn't, didn't...... No, I have!"

"That's right...... I said why this cover is a little familiar to the touch!" Li Ang stood up, "Although I feel when I think about it, but dead horses can be used as live horse doctors, so what's wrong with me giving it a try!"

The Book of Heroic Souls appeared in his field of vision, and Leon looked at the patterns on it, feeling more and more that his judgment might really be right.

"Go!" Leon ordered.

The Book of Heroic Souls floated silently, without any reaction.

"Turn on!"

"Trigger the trap!"

"Transform!"

"Fit!"

......

Tried a dozen of what Leon thought was the starting phrase, but they were all ignored by this mysterious and magical book.

Li Ang was stunned for a while, then suddenly raised his hand and slowly grabbed it, and when he really felt the real touch, he grabbed the Book of Heroic Souls in his hand.

"I've never tried it before!" Leon was so annoyed by his previous negligence that he flipped through it casually, and found that he could only see the patterns and descriptions of the Traveler's Lodge and the Barbarian Sapa, and everything else was blank, and after a cursory count, he found that the number of blank pages was nearly a hundred.

"I don't care about this for now, I believe that a good start is the prelude to victory!"

The Book of Heroic Souls was easily inserted in the middle of several books, and after a long few seconds, there was a soft sound in the distance, and the secret door on the ground gradually opened, revealing a pitch-black space below.

“...... I'm most annoyed with puzzle games!" Ang complained happily, picked up the super torch inserted in the ground nearby, and walked down the winding stone steps of the dark passage, although he was curious about what was hidden in it related to the Book of Heroic Souls, but the disappointment still rose little by little with the continuous downward footsteps, because this place obviously did not lead to the ground.

He wanted to turn back several times, and find another way to get to the ground when he had time!, but in the end he walked briskly, for Leon had a hunch that there might be something in it that would get him out.

Ten minutes later, he was standing on the gentle ground, and in the perception of the battlefield map, there was a dead end not far away, but the light of the torches reflected a wooden door in the stone wall on the other side. Leon walked over and knocked on it, and the sound that came back from Guò could tell that the back of the door was empty, which meant that even the perception of the map could not penetrate the ordinary-looking wooden door. Then he pushed hard inside, and found that the door didn't move under his force.

The young man took a few more steps back, took a closer look, and then picked up the Book of Heroic Souls again and pressed it into a groove in the middle of the wooden door.

With a "click", the wooden door slowly opened by itself, and a burst of light came out, showing a qiē inside the door in front of Li Ang.

It was a small space, and in the middle of the space was a semicircular stone platform, and a long sword was inserted on the stone platform.

"It's been a pleasure to wait for you, Lord of the Covenant. ”

A voice burrowed into Leon's head.
