Without much hesitation, Gu Yun slashed his finger and dripped a few drops of blood into the mechanism. Blood flowed down a small hole into the inside of the mechanism, only to hear a heavy gurgling sound that spun and opened, opening the stone wall against which the skeleton was resting.

"I am really a descendant of Emperor Zhenwu!" Gu Yun watched the stone door being opened, and felt incredible, how many stories were hidden in it? He looked behind the stone door, and behind the stone wall was a stone passageway.

Gu Yun walked into the passage, the surroundings of the passage were polished very smoothly, and the walls on both sides were also lit with oil lamps. Gu Yun walked along the passage, and it didn't take long for him to come to the end. Here another stone gate appeared, and there was also a small hole in the stone door, and in the hole was inlaid with the same mechanism as the previous one.

Gu Yun pinched the wound of his finger again, squeezing out a few drops of blood into the mechanism. Sure enough, the stone door was opened smoothly.

Gu Yun walked in. This is a stone hall with a width of more than 10 meters, a length of more than 20 meters, and a height of 7 or 8 meters. In the middle of the stone hall, a sarcophagus is settled.

Gu Yun didn't dare to open the sarcophagus, and he didn't know if there was the body of Emperor Zhenwu in the Dao. However, since it was his ancestor, he immediately knelt in front of the sarcophagus and kowtowed respectfully three times.

After making a big salute, Gu Yun began to look at the entire stone hall again. On the side facing the door, there is a portrait on the stone wall. On the left and right of the stone hall, there are shelves full of bookshelf, which seem to be bookshelves, and on the shelves are scrolls of books and ancient books.

Gu Yun came to the portrait. The portrait is an old man with a majestic face, and he thinks it is Emperor Zhenwu himself. He was wearing a Taoist robe and was sitting cross-legged, as if he was practicing an unknown practice.

Underneath the portrait is a stone table, on which is a letter with the words "Descendants of my descendants" written on it.

Gu Yun picked up the letter, which he didn't know what material it was, then pulled out the letter paper, shook it open, and looked at it.

"My descendants: When you read this letter, you think that the Great Wu Dynasty has perished, and this mausoleum is one of the backhands I have prepared for you. Both I and the inverse astrolabe are from the Han Dynasty...... Most of the bookshelves in the stone hall are some ancient books that I brought with me at the beginning...... In the wall in front of the portrait, there is a spatial ring, obtained from a strange world...... There is a more advanced version of the Book of Dragons inside the ring, which can replace the one that has been passed down by the royal family...... I have prepared three back roads...... The way to go to the other worlds is in the last pages of the Book of Dragons...... The opening method of the Space Ring is ......"

"It turns out that the astrolabe is called the inverse astrolabe! Well, I'll take out the space ring first! Gu Yun muttered to himself, and then looked at the stone wall where the portrait was. After careful searching, I found that on the stone wall behind the table, there was indeed a mechanism, which seemed to be a place for blood to confess.

Gu Yun did not hesitate to drop another drop of blood into it, and after a while, the mechanism opened, revealing a ring. The ring was unpretentious, and he guessed it was the spatial ring.

Gu Yun took out the ring, followed the steps mentioned in the letter, first dropped a drop of blood on the ring, and after the ring lit up with a dazzling light, he put the ring on the index finger of his left hand. As soon as the ring was placed on the finger, the light on it began to die out quickly. Then, Gu Yun chanted a spell, and the ring disappeared.

Gu Yun touched the position of the ring on the index finger of his left hand with his right hand, and recited the incantation, and the ring immediately came out. He recited the incantation, and the ring disappeared again.

"Sure enough, it's a space ring!"

Gu Yun was overjoyed, just now he recognized the ring according to the method of the letter. Then, he probed his spiritual power into it, and sure enough, he found that there was a cave inside. The whole space is roughly spherical, with a diameter of about 25 meters, and there is already something floating quietly in it.

"But now is not the time to look into this. What if my sister returns suddenly and she can't see my people? I need to get back to the stone hall. Gu Yun reacted, threw his things into the ring, looked at the ancient books around him, put them away, and then strode towards the door.

……

"Hey, where's Gu Yun?" Liu Ruyan heard a scream just now, and thought it was one of her father's gang, so she ran over to take a look, but found that it was not, and then she ran back again. But when he returned to the stone hall, he found that Gu Yun had disappeared.

"It's a passage over there, it looks like it's gone!" Liu Ruyan had already arrived at the stone wall where the abnormality was found, and a hole had been opened in the stone wall, she looked at the entrance of the cave and said to herself, "I'll go over and take a look!" ”

Liu Ruyan climbed over from the entrance of the cave, looked at both sides of the passage, chose the direction to the right, and looked for the past.

……

Gu Yun came to the stone gate, and the stone gate closed automatically after he entered. He looked next to the stone door, and sure enough, he found a control mechanism. As soon as he swirled the mechanism, the stone door opened.

Gu Yun walked out of the stone hall, entered the passage, and then ran quickly towards the stone room in front of him. Now that he had the space ring, the sword in the stone chamber in front of him, he didn't want to leave it to anyone else.

……

Liu Ruyan followed the passage to find a stone hall, and as soon as she cautiously stepped into the door of the stone hall, there was a cry from inside: "Who?" ”

Liu Ruyan followed the prestige, and a young man stared at the door vigilantly. He was about twenty years old, white and clean, dressed in a white suit, giving people the feeling of a jade tree facing the wind.

"Ha Lu Ha Who am I saying, I didn't expect you little beauty to send it to the door by herself!" When the young man saw that it was Liu Ruyan, the crazy Ha Lu Ha Da Lu laughed, and his eyes were full of greed.

"Who are you?" Liu Ruyan's eyebrows were upside down, obviously angry at the young man's light words.

"Little baby, your brother Shiren will love you well!" The young man licked his lips and walked over to Liu Ruyan.

"Phew, nasty embryo! If you dare to come over again, your aunt and grandmother will not be welcome! Liu Ruyan scolded and guarded carefully.

"Hahaha, it's still a fierce horse. Tsk, it's really getting more and more likeable! Shi Ren laughed even more, and hurriedly walked towards the place where Liu Ruyan was.

Whew—

Liu Ruyan pulled out the gentleman's sword and stabbed it at Shi Ren. She is trying to rely on profit and kill her opponent by surprise.

That Shi Ren didn't know where to find a folding fan, and pressed it against Liu Ruyan's sword.

Jingle, the blades of the two people were handed over, and Shi Ren's folding fan was not damaged at all, and it seemed to be some kind of amazing magic weapon.

Liu Ruyan saw that her sword couldn't help Shi Ren's folding fan, so she began to fight slowly, no longer greedy for merit. Shi Ren didn't know what kind of kung fu Lu Dao learned, so he made the folding fan, which seemed to be at ease, and he soon gained the upper hand. But Liu Ruyan has also practiced martial arts since she was a child, and she has already had a little heat, and she can still support it at this time. And so the two men fought.
