The old man's eyes were already sharp, and he raised his fingers, as if he was about to do something.

But after seeing this metal seal clearly, the old man was stunned.

The movement of his hands also stopped.

"Strange, how do you have something from our Tower Guardians."

The old man muttered.

He looked at Gu Qingshan with a strange expression.

Gu Qingshan looked at the seal and gradually remembered what had happened on his way to Huangquan.

He explained: "I saved — no, it shouldn't be a save, someone gave me such a seal anyway." ”

In the dark cavern, the man ended up dead.

But looking at the way that person looks, he looks very glad about it.

He seemed to have a spare body in another world.

The old man listened to Gu Qingshan's words, and became even more confused.

The old man took out a seal and handed it to Gu Qingshan.

"Look, this is my badge, it's exactly like yours, so can I test your badge?"

Gu Qingshan glanced at the badge, it was indeed exactly the same.

In this way, the man did mention it at the time, saying that he was a member of the Tower Guardians Association.

Gu Qingshan said, "Please." ”

"Thank you."

The old man picked up Gu Qingshan's seal and put it in the firelight to study it carefully.

"Separate the false from the true." He muttered.

The flames flew down, wrapping the badge in it.

After a crackling and fierce fire, the fire dissipated.

And the badge was unscathed, shining in the dark.

"It's the real thing."

The old man spoke, his tone becoming serious.

If the other party can get this badge, he is the benefactor of the association, and he cannot use rude ways to probe the other party.

As soon as he thought of this, the old man bowed elegantly and said softly, "I take the liberty of asking, what happened?" If you would tell me the origin of this seal, I would reciprocate. ”

At this moment, a young man ran down the stairs of the tower.

"Teacher, all the guests have arrived, and the time to sail has arrived." The young man said hurriedly.

"You go up first, let them wait." The old man said succinctly.

The young man looked at the old man, then at Gu Qingshan, and reluctantly turned around and left.

Taking this opportunity, Gu Qingshan thought about it for a while.

At the beginning, I was trying to save people, and combined with the attitude of the old man now, it seems that it is nothing to say what happened at that time.

Gu Qingshan organized the language and told what happened.

The old man listened, and looked at the metal seal again.

"Sealed." He said.

The metal seal suddenly emitted a burst of soft light, enveloping Gu Qingshan.

The old man smiled and nodded slightly.

He returned the seal to Gu Qingshan.

"It turned out to be the benefactor of our association."

The old man said, reaching out and pulling hard in the void.

A miniature bookshelf appears out of thin air.

But there were only three books on the shelves.

Their covers are red, yellow, and blue.

"The Six Realms are very special beings, and the Dark Cave is the most worth exploring among them, they show us what an incredible circular structure the magical world of the Six Realms has." The old man talked.

"In the face of the Demon God's modified weapons, although the scholars of the Association have wisdom beyond ordinary people, they are also the most vulnerable existences, and we have always worried about their souls being captured."

"And you saved the soul of a great scholar, which is very commendable."

The old man said, pushing the miniature bookshelf in front of Gu Qingshan.

"Please choose one of these three books as my reward for your heroic deeds."

Gu Qingshan looked at the three books.

There is nothing special about the three books, they all look thick, but the covers are different.

"It's too expensive, and I didn't do anything." He politely declined.

"It's okay, please pick a copy, you're a friend of our Tower Guardian, and if you're polite, it's going to be a dilemma for us." The old man laughed.

Gu Qingshan no longer refused, and said, "But I don't know what these three books are for. ”

"I would venture to say that the murderous aura in you is extraordinary—you should be a person who has killed the souls of hundreds of millions of sentient beings." The old man said cautiously.

"That's right." Gu Qingshan nodded.

In Hell, the dead were disobedient, and he killed entire layers of hell to deter them.

Seeing that he was so calm, the old man also relaxed his tone: "The book with the red cover records some divine skills that are famous for shaking the world of the 300 million layers, if you want, you can take this book now." ”

Gu Qingshan looked at the book with the red cover.

He thought for a moment, and then set his eyes on the other two books.

Three books can be placed side by side, and the other two books are presumably not too bad.

When the old man saw him looking at the other two books, he immediately understood.

He pointed to the book with the yellow cover and introduced: "Traveling in the worlds is an extremely lonely thing, and I see that you are coming alone - I don't know if you have a girlfriend, and I have taken the liberty of preparing this yellow summoning book for you. ”

"The Book of Summoning?" Gu Qingshan said strangely.

"Yes, this book contains the contact details of some beautiful chicks, and you can summon them as companions for a certain amount of time to chat, travel, fight, or do something fun with you - of course, these are paid upfront and there will be no financial troubles."

"There are a total of ninety-seven stunning beauties, who usually walk between the 600 million layers of the world, and each one has countless fans, and everyone is eager to see them."

"These ladies have signed contracts with our tower and are willing to accompany our guests on a wonderful journey." The old man said triumphantly.

Gu Qingshan listened to the old man's introduction, his eyes moved, and he looked at the last book.

Book with blue cover.

When the old man saw this, he continued to introduce: "As for the last book with a blue cover, it is used for communication. ”

"How?"

"I see that you have only mastered a very obscure Terran language, so I have prepared this dictionary of the common language of the Ten Thousand Worlds."

"As long as you hold it, it will tell you all the languages we know so far - there are so many languages in the 900 million layer world, you need about a hundred breaths to master billions of languages."

"Then, please pick a copy." The old man finally said.

Gu Qingshan's gaze swept over the three books.

He suddenly remembered that he had heard the various languages of the waiting crowd outside the tower.

I don't understand a word.

Thinking of this, Gu Qingshan took out the blue-covered book without hesitation.

"Thanks to Your Excellency's kindness, I will accept this book." Gu Qingshan politely expressed his gratitude.

He held the book in his hand, and bursts of whispers came out of it.

Gu Qingshan listened for a moment, and felt that he naturally understood dozens of languages.

"It's amazing." Gu Qingshan muttered.

The old man's expression changed slightly, but there was a hint of appreciation in his eyes.

"Why don't you pick the other two?" He asked.

"Communication is the hardest thing between beings – a lot of times, as long as we can understand each other, things get easier." Gu Qingshan Road.

The old man couldn't help but nod his head and said, "Indeed, this blue book is a great invention that the scholars of our tower have worked hard to complete. ”

"Such a handbook for the knowledge of the languages of all worlds is an extremely precious thing to keep outside, and it is not a problem to buy a layer of the world - of course, this book is only limited to one person."

Gu Qingshan was taken aback, and couldn't help but say, "So expensive? ”

A World Layer......

In one world, there are billions of worlds.

The old man said proudly: "Just like you said, many peerless powerhouses will only discover the importance of language after they step out of their own world. ”

"They can't even talk to each other with others, and that's the most painful thing."

"There are language books for sale in all world layers, and even in extradimensional worlds, but if you want to say that you know the most languages, it must be this blue book of our Tower Guardian."

Gu Qingshan said: "It is also the most expensive." ”

The old man laughed: "A penny, a penny, this is very natural." ”

Gu Qingshan also smiled.

He was actually thinking about something else.

The Tower Guardians Association can collect all kinds of languages in the hundreds of millions of world layers, and what a great strength it requires.

In comparison, what are those so-called peerless powerhouses?

Seeing that Gu Qingshan had already chosen the language of the Ten Thousand Realms to be proficient, the old man put away the other two books.

He led Gu Qingshan down the steep steps all the way to the top of the tower.

The view here is open, and you can see the entire sky and the sea.

There were already three passengers waiting here.

At this time, seeing a new passenger appear, the three passengers couldn't help but look at each other.

"Teacher, the time has passed." The young man walked out from the side and said.

"It's okay, let's destroy the world now."

"Yes."

The young man pulled out a grenade.

He pulled out the pin on the grenade, raised his hand, and threw it into the open sea.

The young man looked at his pocket watch.

"The world has a hundred breaths left before it will be destroyed."

He reported.

"Okay, it's time for us to start the ship, you go get ready first." The old man said.

"Yes."

And the young man took the command and departed.

The old man saluted Gu Qingshan again: "I'm going to be busy, Your Excellency has that badge, and you will be our honored guest in the future, and you can enjoy all the preferential treatment after you get on the ship." ”
