At present, most of the energy mines used in exoskeleton armor come from the academic wonders controlled by humans in various outer spaces.

The Academic Spectacle is an interesting place with all sorts of bizarre things going on.

The biggest disadvantage of the Reiki Energy Mine is its large size and low available energy.

For a person like Liu Fei who can easily use the triple aura formula, the energy mine can't even last for three minutes.

Even after the magic reform, the power furnace that depicts the formula of the 'spirit' field has only increased its energy efficiency by several times, barely able to support a skirmish.

If something like essentia can also be used as an energy source, how much energy can it provide?

Liu Fei came back to his senses, and the matter of the essence of truth could not be known until he got out alive.

There are more important things to do.

He turned around just in time to see a sneaky figure leaving.

Liu Fei smiled: "It seems that our 'teammates' have been paying attention to our safety." ”

Ginny snorted coldly: "Let's go on the road, it's convenient for them, and all the good things are taken by them." ”

Cantor was also dissatisfied: "There are many of them, there is enough time to complete the answer at the same time and then cross the stone bridge, if you are with us, you don't have to be so passive just now." ”

Liu Fei waved his hand: "Don't say anything useless, our purpose is the same, solve Horus and then talk about other things." ”

The castle is right in front of you.

Standing below, you can see the huge oppressive force of this ancient castle everywhere.

The entire castle is at least 300 meters high from the highest point, which is comparable to a human skyscraper.

But its size is much larger than a skyscraper, and there is no end in sight to the huge castle from any direction, and it is hard to imagine how much manpower and material resources would have been required for such a huge structure to be built by humans.

Downstairs is a small mottled bronze door.

It's actually from the perspective of the entire castle, but in terms of this gate, the bronze gate, which is more than four meters high, is just as imposing as it is in front of you.

The gate is covered with delicate and realistic reliefs, depicting all kinds of horrific scenes that look like hell.

The castle is permeated with a twisted and tyrannical aesthetic that is uncomfortable.

Liu Fei gently pushed the door down, and opened it very casually.

He had expected that Horus guy would set up a few more puzzles here.

The bronze door seemed to have not been opened for a long time, and there was a constant unpleasant grinding sound.

Inside is a corridor with no end in sight.

"Who has the lighting?" asked Liu Fei.

A few people shook their heads, and all the extra things before entering the secret realm were handed in, and they had nothing but a pair of clothes.

Liu Fei sighed and looked at Canto Tesla: "Lend me your lighter." ”

"Hit, lighter?" Cantor Tesla's face turned red all of a sudden, "I'm not, I don't, what do I want that thing for." ”

"Come on, pretending to be a good boy with me, the whole school knows about your secret smoking, except for what you think is a secret, and even my neighbor's dog knows how hellish you look like smoking. ”

Cantor Tesla was dumbfounded, and he said with a certain expectation: "That...... Ms. Mercer knows, too?"

Liu Fei rolled his eyes and took out Cantor's lighter directly: "I just said, everyone in the school knows about it." ”

"Woo, I'm not alive anymore, I'm healthy and handsome. ”

Liu Fei went in directly with a lighter, and Li Xin followed closely.

Li Xin asked in a low voice: "Brother Fei, why don't you smoke and have a handsome and healthy image?

"Hi, Ms. Mercer's enemies love to smoke, so she hates all people who smoke, especially men. ”

Li Xin suddenly realized.

He knew who Liu Fei was talking about, and the contradiction between Master Tao Zexuan and Ms. Mose was known to everyone in the entire school of mathematics.

I didn't expect that Cantor, this kid, was quite ambitious, and he dared to think about the Supreme Lord.

I really admire.

The faint flame of the lighter actually can't illuminate much space, and this light is more of a psychological comfort.

Liu Fei could have been illuminated in a simpler way, such as aura radiance.

But sin 9 is hidden in the darkness, and I don't know what conspiracy is planned, and the aura can be saved.

Just now, after killing the aura creatures outside, Liu Fei's stored aura was a third less.

A big family and a big business can't be a loser.

The dark corridor is so large that when you walk in, you find that the top of it is at least twenty meters above the ground.

On both sides are rows of tall columns, and there is no end in sight.

Liu Fei found that the sinners liked to build this kind of living space that only giants needed, wasn't this the style that only the huge demon clan needed?

There is an air of antiquity in the corridors, as if it existed here dozens of millennia ago.

On the delicate marble slabs, there are also paintings of hell.

The sound of footsteps echoed in the giant corridor, and for some reason, Liu Fei actually felt a sense of confusion.

It seems that something important has been forgotten.

What is it exactly?

……

"There's another lovely batch of new students. ”

"Hey, hey, my classroom can't wait. ”

"Tell the kitchen that tomorrow's meat dish can be increased. ”

Whispers came from Liu Fei's ears.

Who am I, where am I, and what am I going to do?

Liu Fei's mind reverberated with a philosophical trilogy.

He struggled to open his eyes, and for a moment, he froze.

In front of me is a classroom full of books, and on one side of the blackboard in front of it is written, "There are 100 days left until the college entrance examination." ”

He sat by the window and looked out, a big river was flowing slowly, wasn't this the big river in his hometown?

River...... Liu Fei came back to his senses suddenly.

Are you back in the world before you traveled back in time?

"Yo, a good student can't get distracted while studying. ”

A voice that spoke in an eerie tone, sometimes high and sometimes low, sounded like a whispered chant behind the ear.

Liu Fei got goosebumps.

He turned his head slowly.

A face with a weird smile happened to stay right in front of him.

Liu Fei's face was expressionless, is it interesting to use the same routine many times?

Really...... This is not the original world.

Liu Fei was a little disappointed.

He looked to the side and saw Cantor lying on the table, seeming to be asleep.

Liu Fei took a half step back.

I can finally see the whole picture of the person in front of me.

This person is a large figure, with a zombie-like face with only a skeleton left, and his whole body exudes a strong evil aura.

Liu Fei clapped his hands and exclaimed, "I've seen you!" Who are you, Pierdan, no! Luther, no! Hey, what's your name?"

Liu Fei crossed his arms: "Forget it, the rebellious dog leg next to Horus, I don't care what the your name is." ”

Carl's smile gradually disappeared, and he looked at Liu Fei coldly: "Jiang Han's road is narrow, and some words are still rotten in the stomach." ”

Liu Fei sneered: "You still want to sink me into the river? Your boss Horus has to abide by the rules, what can you do with me?"

Carl smiled maniacally.

"What can I do with you, get ready to start our game, kid, you're going to love the feast I've got for you. ”

Rumble!

One of the walls of the classroom suddenly collapsed.

Liu Fei's eyes shrank, and the person sitting across the wall turned out to be the team of men in suits.

This gang is coming in too?

Karl let out a maniacian grin: "Expect, my children, the name of this game is only one of the two, and you can only live." ”

Syllable!

Liu Fei's hand smashed the corner of the table, he looked at the zombie-faced Karl coldly, and said, "Have you ever taught at Haifu Experimental High School?" ”
