Dad’s Science and Technology Martial Arts Museum

Hearing this, Chen Xuan immediately lifted his spirits, and then asked inexplicably expectantly: "Tell me, what good things can I exchange for now?"

"Currently, apart from 'recharging', you, the host, can also use money to exchange for all the secret art books collected by this system!"

"From the God of War-level secret technique to the super-universe-level secret technique, you have the authority to exchange it directly as the host... Of course, the premise is that you must have enough money as the host!"

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

"So, if your branch library develops smoothly in other civilized worlds as the host, it can also play a big role!"

"In a word, if you work hard as the host, the more branch libraries you will earn, and the more good things you can exchange for!"

…………

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

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

Especially after obtaining the super-cosmic secret technique Huangquan Jishui, he deeply realized how terrifying a secret technique can cause in a battle with an opponent!

In this way, Chen Xuan is naturally eager to learn a few more powerful secret arts...

"Okay, immediately open the Secret Art Pavilion for you as the host."

The moment the system's voice fell, seven circles of light of different colors suddenly appeared in front of Chen Xuan's eyes - red, orange, yellow, green, blue, blue, and purple.

At the same time, the system's notification sound appeared: "These seven apertures correspond to the God of War-level secret art library, the planetary-level secret art library... the universe-level secret art library, and the super-universe secret art library."

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

…………

"Oh? Sounds amazing!"

With a slight smile on the corner of his mouth, Chen Xuan quickly made a choice in his mind to enter the red aperture.

After a moment, Chen Xuan found that everything in front of him had changed drastically, as if he had come to a majestic ancient library.

The vast collection of classics is displayed in this huge library, and there is no end to it at a glance.

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

Because of the large number of classics, he couldn't believe it was true!

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

"Master, please remain calm." At this time, the system calmly reminded Chen Xuan, "As the master of the Science and Technology Martial Art Museum who is destined to be famous in the endless universe in the future, no matter where you are, you should keep a calm expression and maintain a calm attitude. It's just right..."

"Uh..." Swallowing his saliva slightly, Chen Xuan hurriedly looked serious, and then asked seriously, "System, how can there be so many secret arts here to such a terrifying degree? Where did you get so many of them?" God-level secret technique?"

"It's very simple, because since many epochs of our supreme civilization, almost all the exercises (combat and body skills), secret techniques, and secret law classics of almost all peak ethnic groups are in my hands!"

The next moment, the system replied a little arrogantly: "Among them, there are the top two powerful clans recognized by our endless universe—the Wanshen clan and the Huangquan clan!"

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

…………

Hearing this, Chen Xuan was stunned on the spot, too shocked to speak.

He never imagined that his own system could be so powerful that it could collect the exercises, secret arts and secret law classics of almost all peak ethnic groups since the entire supreme civilization in many eras!

This shocked him to an incomparable degree, and made him even more curious about the identity of the system!

"How does the system do it? This, this,

This is incredible, right? "

Although he was full of confusion and shock, Chen Xuan didn't ask any more questions.

Because he deeply knows that even if he asks, the system will tell him that the time is not ripe enough...

Ever since, Chen Xuan calmed down his turbulent mood a little, and then he went straight to the nearest nanmu bookshelf, and picked up a secret art book with a faint blue cover.

This classic book is called "Blazing Fire Dafa", and it looks like the kind of secret technique that can generate flames.

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

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

"Uh..." Hearing this, Chen Xuan shrugged immediately, and replied with some helplessness, "Then can I understand the power of this "Blazing Dafa" first, and then choose whether to exchange it or not?"

"No." The system immediately gave a very positive answer, "All the classics in the Secret Art Pavilion do not provide specific power introductions."

"Is this okay?" Chen Xuan was naturally speechless, and muttered with his mouth curled up, "It seems that if I come here to exchange secret arts in the future, I must be cautious..."

After muttering a few words like this, Chen Xuan straightened his mind, and then asked again: "Then, please tell me, the system, how much money is needed to exchange this "Blazing Fire Dafa"?"

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

"A God of War-level secret technique is so expensive?" Chen Xuan couldn't help but frowned slightly after listening, "Then the secret technique classics in those secret technique libraries behind will be even more expensive?"

"Don't think it's expensive, host." The system immediately comforted, "You have to know that it's not easy to develop a complete secret technique, and it only sells for 20 million yuan, which is definitely a conscientious price!"

"What you said... seems to make sense!"

Concentrating his mind, Chen Xuan casually picked up a secret technique called "Ice Mirror", and asked, "What about this secret technique, how much can I exchange it for?"

"18.5 million RMB!" The system replied again, "Let's tell the host, in the War God-level secret art library you are currently in, the most expensive one is 50 million RMB, and the cheapest is 8 million RMB. ten thousand yuan."

"So, how much is the planetary level secret technique?"

"Starting at 100 million, the highest is 500 million!"

"What about stellar ones?"
