The runes on the altar are indeed complex, but Agilia is a knowledgeable arcane mage herself, and she is quite skilled at these decryption tasks.

And it seems that these runes are not profound, so it quickly allows Angelia to crack them completely.

Zhang Yuanhang took Flora to her laboratory with Angelia, and saw the altar placed in a clearing.

At this moment, a burst of dark red light began to emerge on the altar, completely enveloping the entire altar.

"Is it up now?"

Zhang Yuanhang pointed to the altar and asked, no matter how it looks, it doesn't look like it can be teleported.

"Of course not." Angelia shook her head, "I've only activated part of the power of the altar, and now a sacrifice is needed to open the teleportation passage and allow us to go to another destination." ”

"Sacrifice?" When Zhang Yuanhang heard this word, he felt a little unhappy and frowned.

"It makes me extremely uneasy, and behind the altar there seems to be a great sin." Flora said in a deep voice, she is a swordsman of judgment, and she is the most sensitive to these.

"Sin?" Zhang Yuanhang was silent, "Is it because Sky City is too dangerous and has devoured the lives of many people, so it is evil?" ”

"Maybe it's just because it's going to be the enemy of the master." Angelia spoke on the side, her expression steady, "For Flora, the justice she stipulates is exactly all the actions of your master, and you are the enemy, and the crime cannot be punished!" ”

"In other words, the other side is likely to be my enemy?" Zhang Yuanhang touched his chin and thought for a moment, "Flora, can you detect whether the evil is a single one or a scattered?" ”

"I'm sorry, no, I can only perceive the sin." Flora bowed her head in shame.

Zhang Yuanhang looked at Angelia: "Then, go on, I'll see what kind of enemy can make Flora feel troubled." ”

Flora's appearance means that the other side is not good at it, and its strength should be very strong.

Otherwise, there are so many people who are hostile to Zhang Yuanhang, and Flora can't take care of them at all, only the kind of enemy who is qualified to threaten him, Flora will show such an attitude.

"I see." Angelia nodded, then clapped her hands.

Dozens of her assistants came in streams, carrying huge iron buckets in their hands.

At that moment, Zhang Yuanhang couldn't help but cover his nose.

In those iron buckets, the bloody smell and stench made him think of retreating.

"What is this?" Zhang Yuanhang frowned and looked at the assistants who came over, pointed to the iron bucket and asked Androlia.

"Flesh, fresh flesh." Angelia didn't look back, keeping an eye on the altar, "I slaughtered hundreds of cattle and sheep, mixing their flesh and blood with everything. ”

Zhang Yuanhang's face changed, and he said in disbelief: "This is the sacrifice?" ”

It definitely can't be a city in the sky on the other side!

This was the thought that suddenly jumped into his mind, the city in the sky was a holy place for spellcasters, and even if any sacrifice was needed, it would definitely not be flesh and blood!

And soon, Zhang Yuanhang saw the changes that had taken place in the altar.

As the buckets got closer, the dark red glow on the altar grew brighter and stronger, and finally it seemed to be about to form substance, turning into winding tentacles that stretched towards those buckets.

Angelia clapped her hands and told her assistants, "You guys put your things down and get out of here now." ”

"Yes." The assistants put down the iron bucket and ran as fast as they could.

Obviously, they were also scared when they saw the change in the altar, and when they heard Angelia's words at this moment, they breathed a sigh of relief in their hearts and immediately ran away.

These assistants are not ordinary people, each of them is an extremely good student in the academy, and after getting permission from Androlia, they came to her laboratory and became her assistants, and through her words and deeds, they gained a lot of hidden knowledge that was unique outside.

Even they left in fear when they saw the changes in the altar, which shows that the altar is indeed very unusual.

"I'll give it a try." Angelia reached out and made a move towards the buckets, and the spell of the mage's hand was unleashed, pulling all the buckets to the altar.

"Be careful." Angelia nodded at Zhang Yuanhang and Flora, and then turned the bucket over.

There was a loud bang, and a large amount of blood mixed with the pieces of flesh poured on top of the altar.

The altar is not large, according to Zhang Yuanhang's eyesight, about seven or eight buckets can cover the altar.

But with the pouring of fresh flesh and blood, the entire altar was like a bottomless black hole, and countless flesh and blood were poured on it, and it was soon swallowed up by a dark red light, until dozens of barrels of flesh and blood were consumed, and there was no flesh left on the altar.

"It seems that the problem with this altar is really big." Zhang Yuanhang muttered to himself, now he absolutely didn't believe that this altar was leading to Sky City.

However, in the news about the castle in the sky, there is indeed an altar.

Either there is an altar that is difficult to distinguish between the real and the fake, or someone has stirred up muddy waters in it, deliberately pulling the altar and the city in the sky together.

So at present, Zhang Yuanhang is indeed interested in this altar.

It's just that I went from trying to find the city in the sky through the altar to finding the secret behind this matter.

"What's next?" Zhang Yuanhang saw the flesh and blood, oh no, the sacrifice had ended, and looked at Androna, "Has the portal opened?" ”

"Nope." Angelia shook her head, "According to the instructions on the altar, after the sacrifice is made, after waiting for a certain amount of time, the path to the coveted destination will be opened. ”

"Dream?" Zhang Yuanhang sneered, "Hmph." ”

Angelia didn't say much, and Flora raised her sword and looked intently at the altar in front of her.

Within two minutes, the door to the lab was opened, and several elemental heroes arrived.

This is the reinforcement that Flora secretly called for after feeling that things seemed to be getting out of hand.

With them on board, even if there is a problem, there will be no problem.

After Zhang Yuanhang turned his head to look at the elemental heroes, he looked back at the altar again, and saw that there was a mutation born.

The dark red glow that gathered together became more and more substantial.

They are tangled together, and they all converge in the center of the altar.

The brilliance was deep, and the dark red light revealed an ominous meaning.

Zhang Yuanhang's expression was gloomy, and he watched as this light gradually turned into substance, forming a circle of light.

Dark red aperture!

In the center of the aperture, there is a faint shadow, but the shaking is so strong and blurry that it is impossible to see what it is.

"This is the portal."

Angelia said to Zhang Yuanhang, "I just don't know what kind of thing is behind it." ”
