Hearing this, Chen Xuan immediately perked up, and then asked inexplicably: "Tell me quickly, what good things can I exchange now?"

"At present, in addition to 'charging', you can also exchange money for all the secret books collected by this system!"

"From the god of war-level secret arts, to the super-universe-level secret arts, you have the right to exchange them directly from the host...... Of course, only if the host has enough money!"

"The money referred to here is not only the money of your human world, but also the money of all other civilized worlds!"

"So, if the host of your branch library is developing well in other civilized worlds, it can also play a big role!"

"In a word, the more hard you work as a host, the more branches you have, the more you earn, and the more good things you can exchange!"

............

After the system finished speaking, Chen Xuan's eyes lit up instantly, and he said in a continuous voice: "System, let me see now what secret techniques are available for exchange!"

Chen Xuan has always been extremely interested in learning secret arts.

Especially after obtaining the super-universe-level secret technique Huangquan Extreme Water, he deeply realized how terrifying the power of a secret technique can be in a battle with an opponent!

In this way, Chen Xuan was naturally eager to learn a few more powerful secret techniques in his heart......

"Okay, open the Mystic Pavilion for the host right now. ”

At the moment when the system's voice fell, seven apertures of different colors suddenly appeared in front of Chen Xuan's eyes—red, orange, yellow, green, cyan, blue, and purple.

At the same time, the prompt sound of the system appeared: "These seven apertures correspond to the God of War-level Secret Art Library and the Planetary-level Secret Art Library respectively...... Universe-level secret art library, super universe-level secret art library. ”

"As long as you make a choice in your heart, you can immediately enter the corresponding secretary library!"

............

"Oh, that sounds amazing!"

The corners of his mouth raised a slight smile, and Chen Xuan quickly made the choice to enter the red circle of light in his heart.

After an instant, Chen Xuan found that everything in front of him had undergone drastic changes, as if he had come to a majestic ancient library building.

The vast number of classics is displayed in this huge library building, and there is no end in sight.

"This ...... So much!" Looking around, Chen Xuan was really taken aback by what he saw.

Because of the sheer number of books, he couldn't believe it was true!

Chen Xuan only felt that compared with this library building, his Langhuan blessed land was simply incomparable, and there was a world of difference!

"Please keep your hosts calm. At this time, the system calmly reminded Chen Xuan in his ear, "As the owner of the Science and Technology Martial Arts Pavilion, who is destined to be famous in the endless universe in the future, no matter where you are, you should be calm and keep ...... of style."

"Uh......" Swallowing slightly, Chen Xuan hurriedly solemnized his expression, and then asked seriously, "System, how can there be so many secret techniques here to such a terrifying degree, where did you get so many god of war-level secret techniques?"

"It's very simple, because for many eras of our supreme civilization, almost all the exercises (battle methods and body methods), secret arts, and secret law books that exist in the peak races are all in my hands!"

The next moment, the system replied a little arrogantly: "Among them, this includes the top two powerful clans recognized by our Endless Universe - the Pantheon Clan and the Huangquan Clan!"

"So, host, what do you think of the god of war-level secret art here?"

............

Hearing this, Chen Xuan's whole person was stunned on the spot, and he was speechless in shock.

He never imagined that his system would be able to be so powerful, collecting the exercises, secret arts, and secret law books that existed in almost all the peak races since the entire Supreme Civilization for many eras!

This simply shocked him to an incredible extent, and it also made him a little more curious about the identity of the system!

"How the hell does the system work? This and this, this is incredible, isn't it?"

Although his heart was full of confusion and shock, Chen Xuan didn't ask much.

Because he knew deep down that even if he asked, the system would tell him that the time was not ripe......

So, easing his surging mood a little, Chen Xuan took a deep breath, and then walked straight to the nearest Nanmu bookshelf, and casually picked up a secret art book with a dark blue cover.

This classic, called "Blazing Fire Dafa", looks like the kind of secret technique that can give birth to flames.

And when Chen Xuan just wanted to open this "Blazing Dafa" to take a look at the contents, he was surprised to find that no matter how hard he tried, he couldn't open this classic.

"Remind the host, no matter which book is in the Secret Art Pavilion, it is not allowed to open and consult it until the exchange is successful!" Almost at the same time, the prompt tone of the system sounded in Chen Xuan's mind, "So, if the host wants to learn this Blazing Fire Dafa secret technique, then please pay a certain amount of money first!"

"Uh......" Hearing this, Chen Xuan suddenly shrugged his shoulders and replied a little helplessly, "Then can I first understand the power of this Blazing Fire Dafa, and then choose whether to exchange it or not?"

"No, you can't. The system immediately replied in the affirmative, "All the books in the Mystic Pavilion do not provide a specific introduction to power. ”

"Is this okay?" Chen Xuan was naturally speechless, pouting and muttering, "It seems that I must be cautious when I come here to exchange secret techniques in the future......

After muttering a few words, Chen Xuan straightened his mind, and then asked: "So, system, tell me, how much money does this Blazing Dafa need to be exchanged?"

"20 million RMB!" The system replied very directly.

"A god of war-level secret art, it's so expensive?" After hearing this, Chen Xuan couldn't help frowning slightly, "Then the secret art classics in the secret art library behind are not even more expensive?"

"Don't be too expensive, host. The system immediately comforted, "You must know that it is not easy to develop a complete secret art, and it is only sold for 20 million yuan, which is definitely a conscience price!"

"What do you mean...... It seems to make sense, too!"

Gathering his thoughts, Chen Xuan casually picked up another secret technique called "Ice Ling Mirror" and asked, "What about this secret technique, how much can I exchange it?"

"18,500,000 RMB!" the system replied again, "Let me tell the host, in the God of War level secret art library where you are currently located, the most expensive secret art is 50 million yuan, and the cheapest is 8 million yuan." ”

"So, how much is the planetary-level secret art?"

"Start with 100 million, go up to 500 million!"

"What about the stellar ones?"
