"This book can't be written with an ordinary pen. The Emperor of Heaven has a pen dedicated to writing the rules of the sky. If you defeat him and grab that pen, you can write the rules of the sky."

Hearing this, Tang Guo returned the book: "Then wait until I defeat the Emperor, and then go to Senior to get it. If it is robbed, it would be no good to destroy it."

"It doesn't matter, I want as many as I want for this thing," he said, and the old man flicked his sleeve, and there were many books on the ground with the word "Heaven" on the cover.

The old man is surrounded by books like this, just like a big money, if it wasn't for the other party to look unfathomable, Tang Guo would think he was just a wholesaler.

"Why didn't the senior **** the pen back by himself and write the rules?" This is something Tang Guo doesn't understand. This old man doesn't seem to be tied here.

The old man seemed to know that Tang Guo would ask this question, stroked his beard, shook his head and said: "I can't write, I can't hold the pen, can't touch it, can't get it."

"At the moment you walked into the underworld, I had calculated the future direction. The first line of life in this world lies with you. If you can't succeed, you don't know how long it will take to change the rules of the sky. Maybe, wait until this. If Fang Tiandi is destroyed, that day may not happen. Fortunately, you are here."

Seeing that the old man was reluctant to say anything, Tang Guo didn't ask, and left with a blank book. This old man has so many, he is not afraid of destruction.

In fact, it fell into her hands and it was basically impossible to destroy. She just thought that something so important fell into her hands suddenly.

Tang Guo smoothly returned to the former site of the Sea Dragon Palace without any obstacles.

"How's it going?" Seeing her safely back, Ao Yan heaved a sigh of relief, "Is there anything troublesome?"

"No, everything went well." Tang Guo simply said what he had heard in the past, "The Hades from the underworld may have discovered me, but he didn't say anything. He knows about the abnormality in Tangjia Village, listen to him. It means I don’t plan to manage."

Ao Yan was not surprised at all. Instead, he said: "The King of Yan will not participate in the battle of the immortal world. He only cares about ghosts and the underworld. This is his style. My friends and seniors are able to spend nourishment in the underworld, thanks to the care of the king. However, I am not very familiar with him."

These things were actually found by Ao Yan in the memories of the Dragon Clan seniors.

One of the reasons why the dragon clan was jealous of the emperor was that the inheritance of the dragon clan was simply beyond the control of the emperor.

"You said, that 18th-floor strong man, let you go to the emperor to grab a pen and write the rules of the sky?" When Ao Yan heard this, he was particularly surprised. The flames in his eyes seemed to burn even more. Exuberant, "You really have a silver lining."

"Ao Yan, do you know who the senior on the 18th floor is?" Tang Guo was a little curious about the identity of the other party, and vaguely guessed, but still not sure.

Ao Yan shook the dragon's head: "I don't know, he was there before the accident happened to the dragon clan. I have heard the predecessors of the dragon clan mention him. I only know that he is very powerful. I don’t know why he was locked up on the 18th floor of the underworld. I didn't even plan to come out. In short, it is an unprovoked existence. As long as he does not appear, even the Emperor of Heaven will not do anything to him."

"Why, do you have any guesses?"

"Some, not sure, but it's not important. Ao Yan, practice."
