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

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

His movements also stopped.

"Strange, how could you have something from our tower guardians."

The old man murmured.

He looked at Gu Qingshan with a strange expression.

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

He explained: "If I have saved me, that should not be considered a rescue. Anyway, someone gave me such a seal."

In the dark cave, the man died in the end.

But looking at the person's appearance, I was very grateful for it.

He seems to have a spare body in other worlds.

The old man became even more confused after hearing Gu Qingshan's words.

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

"Look, this is my badge, it's exactly the same as yours, so can I check your badge?"

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

In this way, the man did mention that he was from the Tower Guardians Association.

Gu Qingshan said, "Please give me some advice."

"Thanks."

The old man picked up Gu Qingshan's seal and placed it under the flames to examine it carefully.

"Get rid of the false and keep the truth." He murmured.

The fire flew down violently and wrapped the badge in it.

After a crackling and violent burning, the fire dissipated.

The badge was unscathed and shone in the darkness.

“This is the authentic product.”

The old man said, his tone becoming serious.

If the other party can get this badge, it is the benefactor of the association. You cannot use rude methods to investigate the other party.

As soon as he thought of this, the old man bowed gracefully and said softly: "I'll ask you, what happened? If you are willing to tell me the origin of this seal, I will be rewarded."

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

"Teacher, all the guests have arrived, and the time for the boat has come." The young man said hurriedly.

"You go up first and let them wait." The old man said concisely.

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

Taking this opportunity, Gu Qingshan thought about it.

At the beginning, I was trying to save people, and combined with the current attitude of the old man, it seemed that it was nothing to tell the matter at that time.

Gu Qingshan organized the language and explained the story.

After hearing this, the old man looked at the metal seal again.

"Certify." He said.

The metal seal suddenly emitted a soft light, covering Gu Qingshan.

The old man smiled and nodded slightly.

He returned the seal to Gu Qingshan.

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

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

A miniature bookshelf appeared out of thin air.

But there were only three books on the bookshelf.

Their covers are red, yellow and blue.

"The Six Path World is a very special existence, and the dark cave is the most worth exploring place. They show us what an incredible circular structure does the Six Path World have," the old man talked.

"In the face of demons' modified weapons, although the association scholars have wisdom beyond ordinary people, they are also the most vulnerable existences. We have always been worried that their souls will be captured."

"And you saved the soul of a great master, which is very appreciated."

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

"Please pick one of these three books as my repayment for your heroic behavior."

Gu Qingshan read the three books.

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

"It's too much, and I'm not doing anything," he declined.

"It's okay, please choose one. You are a friend of our tower guardians. If you are polite, you will be a dilemma for us." The old man smiled.

Gu Qingshan stopped refusing and said, "But I don't know what these three books are for."

"I'll say it a prudently, I think the murderous aura on you is extraordinary. You should be a person who has killed the souls of hundreds of millions of sentient beings." The old man said carefully.

"That's right." Gu Qingshan nodded.

In hell, the dead were disobedient. He had killed a whole layer of villains from hell to shock them.

Seeing that he was so calm, the old man relaxed his tone: "The book in the red cover records some magical skills that are famous in the 300 million levels of the world. If you want, you can take this book now."

Gu Qingshan looked at the book with a red cover.

He thought about it and turned his eyes to the other two books.

If the three books can be placed side by side, I believe the other two will not be too bad either.

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

He pointed to the book with a yellow cover and introduced: "Traveling to all worlds is an extremely lonely thing. I see you are here alone again. I don't know if you have a girlfriend. I took the liberty to prepare this yellow summoning book for you."

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

"Yes, this book contains contact information for some beautiful girls. You can call them as partners within a certain time to chat, travel, fight, or do something else interesting. Of course, these have been paid in advance and there will be no financial disputes."

"There are ninety-seven beautiful beauties in total. They usually walk between the six hundred million levels of the world. Each has countless fans and everyone desires to see their beauty."

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

Gu Qingshan listened to the old man's introduction and looked at the last book.

Book in blue cover.

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

"How to say it?"

"I think you only master a very remote human language, so you have prepared this dictionary of universal languages ​​in all worlds."

"As long as you hold it, it will tell you that the language we know so far is too many languages ​​in the 900 million levels of the world. It takes about a hundred breaths to master billions of languages."

"Then, please pick one." The old man said last.

Gu Qingshan's eyes swept across three books.

He suddenly remembered the various languages ​​he heard from the waiting crowd outside the tower.

There is no sentence you can understand.

Thinking of this, Gu Qingshan pulled out the book with a blue cover without hesitation.

"I will accept this book thanks to your kindness." Gu Qingshan politely expressed his gratitude.

He held the book, and whispers suddenly popped up in the book.

After listening for a moment, Gu Qingshan felt that he naturally understood dozens of languages.

"It's so magical." Gu Qingshan murmured.

The old man's expression changed slightly, but his eyes showed a hint of admiration.

"Why don't you choose the other two?" he asked.

"Communication between sentient beings is the most difficult time. As long as we can understand each other, some things will become simple." Gu Qingshan said.

The old man kept nodding and said, "It is true. This blue book is a great invention that our scholars in the tower have exhausted their efforts to complete."

"This book of language knowledge in all worlds is an extremely precious thing to put outside, and it is not a problem to buy a new level of the world. Of course, this book is only limited to one person."

Gu Qingshan was startled and couldn't help but say, "So expensive?"
