Olivia tapped her fingers on the wooden table, as if thinking about something.

"How many humans do I need to sacrifice for a piece of philosopher's stone as large as mine?"

Edward muttered for a moment.

"About a dozen."

"So much?"

"Yes, this is still a conservative estimate, I have studied the information of the Philosopher's Stone in detail."

Olivia continued: "What if it's the size of an egg?" ”

"What!"

Edward looked at Olivia in horror.

"Don't be surprised, I did see that big piece two days ago, and this piece was detached from it."

Knowing the origin of the Philosopher's Stone, Olivia began to feel the weight of the red stone in her hand.

"If it's such a big piece, I can't imagine who is holding such a large piece of the Sage's Stone?"

“……”

Ovellia didn't say that it was Su Xiao, she had a vague feeling that the other party was indeed here to form an alliance with her.

If you really want to fight against the Central Army, then the alchemist is particularly important, and the alchemist of Metal in front of him is also a combat force.

"I have a general understanding, tell me the purpose of your visit this time."

Ovilla's tone was calmer.

"We're here to ......"

The Elric brothers recounted their purpose of coming to find a little girl with a red panda and ask the little girl for alchemy.

The Elric brothers had already seen the Bottle Man, the man who looked like their father.

In front of the villain in the bottle, their brother's alchemy failed, no, they couldn't use alchemy at all.

On the other hand, in alchemy, the little girl and Scarface are in full swing with alchemy and androids.

Edward already had a vague sense that the man who looked like Hohenheim might be the mastermind of everything, and the androids called him his father.

"I see."

Olivia looked at the portrait in his hand, which depicted a red panda.

"We're just going to find its owner."

Just as Olivia was talking to the Ellik brothers, a soldier slammed the door in.

"Major General, something is wrong!"

"What's the matter, don't panic."

"Yes...... In this way, a monster suddenly sprang out from the ground and was in the lower base. ”

"Monsters?"

"Yes, monster."

Olivia's brows furrowed, and trouble appeared one by one.

"Where is it?"

"Near the arsenal."

As soon as the soldier finished speaking, Olivia stood up and rushed to the lower level of the fortress.

The arsenal is the foundation of the fortress, and if you lose your weapons, the surrounding enemy countries will immediately attack.

The Ellik brothers followed behind Olivia.

"You two don't have to come along."

During the run, Olivia turned to look at the Elric brothers, who were friends and foes.

"We can help, don't forget that we are alchemists, and we will not sit idly by if there is trouble in the fortress."

Edward grinned.

"Obey the command then, and if you act without permission, don't blame me for being unkind."

"No problem."

Olivia nodded secretly, the two brothers showed no ill will.

The group quickly rushed to the lowest floor of the fortress, which has been more than ten meters underground, and the entire fortress has dozens of floors above ground and three floors underground, which is used to store weapons, food, etc.

……

Inside the underground building of the fortress, in an empty square.

This is a weapons testing facility, the fortress develops weapons, and this is the testing site for weapons, surrounded by steel structures, which are very strong.

A strong man with a height of three meters and angular muscles all over his body is under siege.

Bang, bang, bang......

Dense bullets hit him, but the strong man didn't even break his skin.

"It hurts, it's troublesome."

The strong man spoke slowly and slowly, showing a very lazy appearance.

"It's so big here."

The strong man only has one eye, and the position of the other eye is a red node, just by looking at the appearance, you know that this is not a normal human.

The Elric brothers rushed out of the staircase, and at a glance they noticed the red pattern on the strong man's shoulder, which was a round Ouroboros.

"It's ...... Android! ”

Edward immediately recognized the identity of the strong man, and his heart was a little uneasy, the two brothers had come here to find a way to deal with the androids, and his first reaction was that the androids had seen through his plan.

"We're just here to find a way to recover."

Edward's explanation was a bit weak, he had been threatened by androids before, and if they dared to act rashly, his childhood sweetheart's life would be at risk.

"Who are you?"

The identity of this strong man is self-evident, Lazy Sloth.

Unlike other androids, Sloth Sloth has a low IQ and is dull by nature, and his dream is to sleep all the time.

"By the way, dig a hole...... Trouble is dead. ”

Sloth's mission was to dig a circular passage beneath the subterranean realm, and what he was digging was the energy channel of the Territory's refining array.

"I want to sleep...... Trouble is dead. ”

Lazy Sloes walked slowly to the side, roaring with every step, this guy was not lightweight.

"Get out of the way!"

A woman's shout was heard, followed by a roar.

Olivia stood inside a tank, half of her body exposed.

"Ready."

The muzzle of the tank began to turn.

"Fire!"

Rumble!

Olivia is not interested in communicating with Sloth, the other party has already invaded the arsenal, and Olivia will not listen to the other party's explanation.

A cannonball slammed directly into Sloth's face, and the cannonball exploded.

The flames and smoke enveloped Sloth, and the soldiers present breathed a sigh of relief, the enemy had been dealt with, and no one could resist this shelling.

The smoke cleared, and Sloth's figure appeared, only a slight injury appeared on his cheek, red lightning flashed, and his injury recovered.

"How is this possible, the shells actually didn't work."

The morale of the Northern Army was frustrated, and no matter how brave they were, they were a little at a loss in the face of such an inhuman monster.

Ovilla was stunned for a second before reacting.

"Don't be stunned, reload!"

A dozen seconds later, the tank opened fire again, this time with solid shells for more lethality.

Boom, the muzzle of the tank burst into flames.

A dark red cannonball struck Sloth in the lower abdomen, and Sloth only took a slap in his body, and the solid cannonball was bounced off, smashing a small crater in the ground.

"It's painful, it's painful, it's troublesome, by the way, you have to work."

Lazy Sloes simply ignored the shelling, he was too lazy, too lazy not to fight, not to talk.

Boom, boom......

Solid cannonballs hit Sloth.

Sloth's body shook, as if he had been beaten impatiently, and he easily lifted the steel pipe pile to the side and smashed it into several tanks.

With a bang, one tank was smashed into a chunk, and several other tanks immediately retreated.

"Don't stop shelling."

Olivia was a little helpless, this inhuman monster was the first time she had encountered it, and she couldn't think of an effective countermeasure for a while.

"Olivia, as an ally, why didn't you notify me if something happened in the fortress."

A voice came, and Olivia looked up at Su Xiao sitting on the iron fence on a high place, with a smile on his face, a cigarette in his fingertips, and a dog behind him.

"Do you have a way to deal with this monster?"

Olivia's eyes narrowed slightly, she had already felt that this Flame Alchemist was not simple.

"I was wanted by those guys for killing humans."

Su Xiao jumped down from the railing.
