Big engineering tower.

63rd floor.

Living quarters.

Deng's office.

A Deng, a great engineer, was dressed neatly. There was no secretary or female student inside. He was happily making black tea.

Suddenly.

"Why was the name cut out?"

"Poof - cough..."

A mouthful of tea that Deng had just drunk was so frightened that it gushed out.

Almost choked.

After coughing for a long time, Deng turned his head in shock and stared at the "explosion student" Yilin who ran behind him at some time. His expression was like seeing an unscientific existence.

"You, you, you, when did you come in?"

"Just now."

"But I locked the door..."

"You didn't lock it."

"But I know..."

Yilin sighed: "I don't think you want to see the message, 'a Deng, a great engineer, suffers from Alzheimer's disease and brain disability', spread all over the College of engineers in an hour?"

"Oh, I remember. I forgot to lock the door."

Deng looked at the door that had not been opened at all not far away and said against his heart.

Yilin didn't continue to tangle with such details. He slowly circled around and walked in front of Deng and got stuck between "Deng" and "door".

This is the only door to leave the office.

There is also a hidden exit under the crystal ornament on the right.

Yilin knows everything and blocks all the routes in case ah Deng doesn't talk about martial morality and runs away.

"Pa."

Yilin photographed the shabby world history with few words and paragraphs on the table, smiled kindly and repeated the problems that Deng didn't hear clearly not long ago.

This time, Yilin's tone was very polite.

"Excuse me, my respected tutor, why is this name all cut off?"

Deng wiped the tea at the corner of his mouth.

He looked down.

After seeing the book in Yilin's hand, he suddenly drew his eyebrows and whispered: "the book is on the 54th floor..."

"Huh?"

"Well, I mean, why are you suddenly interested in 'world history'."

Yilin shook his head, stared into the eyes of a Deng, the big engineer, and said slowly, "I'm not very interested in 'history'. What I'm interested in is that there are two words on it that I didn't have time to cut out."

"Evil gods."

Deng was stunned and became silent.

A few seconds later, Deng wiped the sweat from his forehead and said to himself, "it's not clean..."

Yi Lin: "

"Ah --" Deng suddenly smiled, stretched out his hand and quietly wanted to take the book from the table. He said, "in fact, this book is too old, and there's nothing to say. Why don't we..."

Yilin didn't stop Deng from taking the book, but narrowed his eyes and showed a kind smile.

"If you let the Dean know that you secretly watch 'Bunny portrait'..."

“?”

"If you let the vice president's wife know that you often peek at the tight buttocks of female students' engineering clothes in the yard during the day..."

"Sleeping trough?" Deng suddenly became angry, patted the table and got up. He was so angry that his beard rustled and trembled, and his voice trembled into a wave: "you, you, how dare you peep at me? Where do I look at my bag, my hips? I look at my legs!"

Yilin sighed again, "you even the dean's wife --"

Pop.

Deng held Yilin's hand tightly. The movement was fast and the handshake was tight, which was very like a lover who never left for generations.

"Let me talk carefully."

……

……

Deng was helpless.

We can only start the class again for the "explosion students" who have avoided for many days.

This section is "world history".

He touched his face subconsciously.

It's just healed.

This class, without any loop practice, should, may and may not have any accidents again.

Deng drew a "circle" on the blackboard.

Wrote a string of words in the circle.

——[Uranus].

"Although I have always made you believe in science, you should know that there are 'gods' in this world."

Yilin raised his hand and answered, "Uranus."

"The answer is correct," Aden said approvingly. While drawing seven dots in the circle, he explained: "at the beginning of the creation, the God 'Uranus' created the world with seven giant beasts above the clouds. The seven giant beasts are Gaia, Eros, poros, pagos, Aurora and Poseidon."

Yilin kindly reminded, "mentor, you only said six giant beasts."

Deng suddenly became silent.

"The dean's wife..."

"Cough, forget it. In fact, there's nothing to hide. The seventh giant beast is the two words that haven't been removed in time in 'world history', which represents the evil god of 'the extreme darkness of the world'."

At the moment when he said that even one word, Deng subconsciously looked around and didn't know what he was looking at.

"Why did you pull it off?"

"Because," Aden saw that there was no special situation after saying those two words. He breathed a sigh of relief and continued, "two thousand years ago, that is, in 1333, it is said that there was a 'Divine war' in the world. The seventh giant divine beast was dissatisfied with the rule of the God Uranus over the world and launched a war against the God."

"The specific situation of that war has been annihilated in history. But the only thing we can know is that before the 'Divine war', there were no 'demons' in the world, but the blood of the seventh giant beast scattered all over the world and turned into all kinds of demons."

Yilin bowed his head to think and whispered to himself, "it turns out that the final boss is such a setting."

"Huh?"

Deng didn't hear clearly: "what are you talking about?"

"No, I said so..." Yilin scratched his finger, opened the panel, stared at the current target of the "main task", and continued to get the information of the main task from Deng: "where is this giant beast that is forced by cattle now?"

"No more."

Yilin was stunned.

What?

Boss is gone?

Who am I going to brush?

"You're gone?"

Deng glared at the explosion student Yilin, smoothed out the subject, predicate and object of the whole sentence, and said again: "the seventh giant beast fell!"

“……”

After this class, Yilin asked repeatedly that old Deng didn't change his confession.

Yilin even threatened to build 108 large "amplification circuits" in each floor of the corridor and sing all Deng's secrets a hundred times. But Deng said directly: that's the truth. Kill me!

The answer of this broken jar was stunned, which made Yilin uncertain whether he really wanted to let the poor old man die socially.

It's not easy to fall in love at dusk.

What a pure spiritual partner.

In fact, Lao Deng just secretly chatted with the president's wife.

Yilin thought and decided to let ah Deng go for the time being.

After all, Yilin still has a lot of knowledge and needs to find a Deng to answer.

"Is the boss really dead in the end?"

"Wait a minute..."

Yilin opens the [task] panel again.

The content of the main task remains unchanged.

In other words, the information he currently obtains is not enough to complete the current task.

[current mission objective: find more clues about "evil gods".]

Yilin rubbed his eyebrows depressed.

For more clues, the system makes the task clear. How many clues can you find to complete the task?

Isn't it a long way off?

Although Irene now enjoys the game.

It's not unacceptable that I can't leave here for a while and a half.

But Yilin didn't forget that he didn't know what kind of situation his body was in the "reality".

In case the life support module doesn't have enough energy.

In case of power failure in reality.

Or what natural and man-made disasters have happened in his "real" home.

Isn't he cool?

Returning to the real world is the only "main task" that Yilin urgently needs to complete.

……

……

Knowing that the time was pressing, Yilin compressed the rest time and squeezed out more spare time as much as possible. He soaked in the 54 floor library and deeply remembered the various books of "crystallography" and the examination key points, difficulties and sites of various crystallography.

It doesn't matter if you can't fully understand it for the time being. He believes that in practical application, as long as the knowledge is firmly remembered, everything will soon be integrated.

Erin sat on the bare floor of the library.

The floor was spotless.

Yilin stretched out a finger, thinking and subconsciously gesticulating on the floor, simulating the construction of various functional circuits.

For a moment, Yilin recalled that standing at the top of the Vatican branch in port isita, in the center of the seven huge white crystals, he witnessed the whole process of the mysterious and complex circuit from start to stop.

At that time, Yilin saw it and only felt some meaning. After systematically learning "crystallography", he recalled that "circuit", but he had different ideas.

"It's strange that many places seem to understand that 'loop', but they are connected together, but they don't know how it works. With only that loop, a defense shield can be generated out of thin air that can cover a large port city?"

"If I'm right, that circuit is composed of seven main cores and 56 sub cores, supplemented by countless' nodes' and 'patterns'. But normally, seven main cores and 56 sub cores alone can't completely provide the' energy 'required by the defense shield."

"Complete?"

Yilin's brain was like a flash of light and chewed these two words carefully.

Yeah!

That circuit is incomplete.

Always give Yilin a feeling of "what's wrong".

"In crystallography, the most fundamental principle of building a circuit is the 'tightness' and' integrity 'of the circuit. For an incomplete circuit, crystal energy cannot flow. By the way, it is like' electricity ', which does not form a closed' circuit ', and there is no way to generate current."

"Although crystallography is a black technology in the game world, it should also be a similar principle. Wait, what is this..."

Erin was sitting on the floor.

Each smooth floor tile on the ground is engraved with some decorative patterns.

"This is..."

Yilin's face was frozen. He carefully pushed away several bookshelves nearby, cleared an open space, and then carefully figured out the texture on the floor tiles.

"I remember the map of isita port seems to be..."

Elaine closed her eyes.

Not long ago, because it was convenient to move, the map of isita port recorded in his mind was turned out again by Yilin and afterthought carefully.

Yilin sat alone in the library.

There is no one here except him.

Yilin did not move, just like a sculpture.

If it weren't for Yilin's chest, which was still fluctuating with a fixed rhythm, maybe someone accidentally broke into the 54 storey library at this time, and would mistakenly think that the legendary "explosion student" who blew up several floors of large engineering towers died suddenly in the library because of exhaustion.

I don't know how long it took.

Yilin suddenly opened his eyes and smiled.

"I see."
