Cheng Zhong looked up at the endless metal bookshelves and the thousands of books in uniform on the shelves, and for a moment he had mixed feelings.

First of all, he could not understand where the contents of these books were collected.

Secondly, regardless of Lao Fengniao's own creations, he couldn't believe how Lao Fengniao could have such an incredibly powerful memory ability.

Third, it was hard for him to imagine how many days and nights it would take to copy and create the vast volume of books in this vast hall.

In the small circle of people living on Earth, almost everyone praised Cheng Zhong for being clever.

After entering the wolf domain, it is even more amazing, almost all the Wusun people think that he is a little prodigy, an all-knowing and omnipotent angel.

But at this moment, standing in front of these tall bookshelves, Cheng Zhong felt as small as an ant and as ignorant as a mosquito.

His own little cleverness and cleverness, compared with the old phoenix bird of his master, is like the waterlogged dam in his hometown is better than the boundless ocean, and the grass on the ground is more than thousands of feet of green pine.

Once again, he truly experienced the ancient adage that "there are mountains outside the mountains, and there are people outside the people".

He was ashamed of his ignorance and that he had always felt good about himself.

He was also very fortunate and proud to be able to meet the great old phoenix bird and worship him as a teacher.

To tell the truth, the shock and excitement that this vast underground library brought to Cheng Zhong far exceeded the unity of a pocket of RMB in the snow, and it was far more than the room full of gold, silver and jewelry in Xu Shoujun's underground secret room.

He vaguely felt that God had really shown an immeasurable opportunity in front of him this time.

Here, the mysterious universe seems to have opened a bright window to him, through which he can understand the truth step by step and approach the truth step by step if he wants to.

Understanding the universe and exploring the truth has been his yearning and pursuit since he was a child, and it is the greatest meaning of his life.

Thinking of this, Cheng Zhong's breathing accelerated, his heart beat faster, his blood surged, his face was red, and his lips trembled involuntarily.

He knew he was too excited.

Suddenly, I remembered what the old phoenix bird had just said, and I silently recited in my heart:

"No matter how much you like it, nothing is ultimately your ......"

After repeating it ten times in succession, I felt that my heartbeat gradually stabilized, my head became clear, and my body returned to normal.

The old phoenix bird was silent, and watched coldly there.

Cheng Zhong's series of reactions seemed to be as he expected, but also as he expected.

He had just analyzed Cheng Zhong's reaction in the Ecstasy Array, and felt that power and fame should be the highest pursuit of this Terran boy.

Now seeing his reaction to the massive number of books in his library, I feel that the previous analysis is actually not accurate.

His analysis of reactions in the ecstasy is aimed at the desires of ordinary people and living beings, but simplifically divides complex desires into three types: power, fame, wealth, and beauty.

The reaction of his own disciple shows that he should belong to the first category.

But judging from his current reaction, it seems that his pursuit of knowledge and the truth of the universe is more persistent than his pursuit of power and fame.

This kind of pursuit is the highest level of pursuit in the universe.

The creatures who have this kind of pursuit are the most cherished creatures in the universe.

Ask yourself, since the old phoenix bird has self-awareness, in addition to the pursuit of "love" that the old phoenix bird will never give up, the highest yearning and pursuit is also the truth of the universe.

It was because of this pursuit that when he was on earth, He asked the two immortals to find all the human books they could find for Him to read, and the two immortals gladly fulfilled His request.

The old phoenix's brain has a function similar to that of a camera device, which makes his memory invincible in the world.

He left Earth for the Wolf Domain more than a thousand years ago, and all the books he had read and memorized before that.

The Wolf Domain is ten times faster than the Earth, so he has spent more than 10,000 years in the mantle layer beneath the volcano of the Wolf Domain.

In the long years, in addition to completing the tasks assigned by the two immortals, he used his supernatural powers to create an underground world of knowledge.

He wrote diligently every day, copying down all the books He had read on earth.

He thought carefully and studied it, and wrote about his knowledge and insights in various fields.

It is precisely because of his continuous study and research and continuous communication with the old phoenix bird that the more than 10,000 years of time will not be too bitter, so that he and his beloved wife will not go crazy due to emotional disorders.

The greatest scientist of mankind may catch up with or surpass Lao Fengniao in the level of research in a small field of his own, but when it comes to the overall understanding of the universe and the comprehensiveness and comprehensiveness of the discipline, there is absolutely nothing beyond it......

I don't know how long it took for Cheng Zhong to come back to his senses, look at the old phoenix bird with adoring eyes and say:

"Oh, Master, everything you have here shocks me, my eyes are not enough, my brain is not enough, my mouth is open and I want to ask questions.

Why don't you lead me to find a weapon that I might use, and then tell me about your situation here?"

"Okay, let's go forward and give you a brief introduction as a teacher.

But don't be too impatient and try to figure everything out at once. ”

The master and apprentice walked side by side along the passage in the middle of the bookshelf, talking as they went.

It turns out that the bell is now located in the transition zone between the mantle layer and the crustal layer.

With his magical powers, Lao Fengniao has built a long hall of about ten kilometers here, and his various research and production results are placed in turn.

First there is a library about a kilometer long, then a metal warehouse about five kilometers long, then a gem warehouse about two kilometers long, then a chemical experiment warehouse about a kilometer long, and finally a new goods warehouse less than a kilometer long, where weapons are stored.

Entering it, the feeling of Cheng Zhong is a hundred times more amazing than the feeling of "Grandma Liu entering the Grand View Garden".

All kinds of metal classification codes in the metal library are neatly placed, gold, silver, copper, iron, lead, zinc, aluminum, all common metals are available.

The largest block is against the ceiling, like a shipping container on a ship, and the smallest is the size of a finger.

"The two immortals asked the teacher to keep a part of the pure metal that was replaced by the chemical reaction, and soon filled the five-kilometer corridor hall, and I felt that it would take up too much space in the future, so I no longer kept it.

If you can use it one day, as long as you have a way to take it away, take it as you like, ho ho. ”

The old phoenix bird waved his hand disdainfully as he walked forward.

As Cheng Zhong walked, he heard a voice in his heart say:

"With so much metal, if you get it all out to build weapons, I don't know how many troops you can equip yourself. ”

Before the words could be spoken, another voice said in a loud voice:

"Don't be so petty, why admit death, you have to build any sharp weapons, as long as there is a way to eliminate the 'Flying Dragon Gang', wouldn't it be more labor-saving if you don't make weapons!"

He blushed and shook his head, shook off the messy thoughts, and followed the old phoenix bird without saying a word.

It was a full hour before they entered the treasure store.

The gems are also of all kinds, the big ones are like houses, and the small ones are like birds' eggs.

In the front of the ecstasy array, Cheng Zhong was tempted by the gems, and almost delirium, this time he simply didn't look at these gems as if he was angry, and they were all stinky stones next to the toilet in the back of his old house.

Don't say it, when people's minds change, the world is completely different.

The gems were piled up, and the mystery of their scarcity was lost, and Cheng Zhong thought of them as stinky stones, and the original mesmerizing jewels were gone.

"Hehe, the reason why gemstones are precious on earth is because the possibility of relying on nature to form such pure quality stones is very rare and scarce.

In this case, the rock needs to be constantly modified to extract the metal.

The number of gemstones formed in this process is beyond measure.

I started to love all kinds of gemstones, so I left some here.

Now it's not very common, and it doesn't take up space, so I don't collect it anymore, and I mix it all into the lava. ”

The old phoenix bird said.

After that, the master and apprentice entered the chemistry experiment bank.

This is where the old phoenix bird conducted experiments to remove metals from ores on a large scale, and it is also the place where he made chemical creations.

Because considering that Cheng Zhong did not understand chemistry at all, Lao Fengniao did not make any explanation, and directly led Cheng Zhong through quickly.

After a long journey that could almost be described as a long journey, the master and apprentice finally reached the warehouse where the weapons were located.
