She pulled out a piece of metal from her inventory, a round piece, the size of an adult's palm, covered with tiny and dense elements, some so small that they could barely be seen.

The system beep sounds again.

[Ancestral Map of Mechanical Civilization: From the ancient mechanical civilization, recording all the scientific and technological information of the ancient mechanical civilization. System Rating: Perfect Orange]

Ding Xuan was so shocked that he couldn't speak, the rating given by the system was actually Perfect Orange, Innate Spirit Treasure! That's the highest level in the system!

But it's right to think about it, this piece of metal records all the civilization materials in the mechanical civilization, it is a whole civilization, including countless science and technology, if all of them are developed, maybe the entire earth will be brought to a higher level of civilization, and interstellar travel will not be a dream at that time.

Such a treasure is in her hands, how can she not be excited?

This is probably the thing that Wang Lao wants to snatch.

She sank her consciousness into the metal and was bounced out, wasn't it driven by her divine sense? She injected her spiritual power into it again, and she sank into the sea like a stone, and there was no reaction. She frowned, remembering that many things needed blood to recognize the owner, so she bit her index finger and dripped a drop of blood on the metal, but still nothing happened.

She put the metal into the jade space, and when she returned to the trial space, she would ask Gis.

She looked at a few passages around the atrium, and the road where Wang Liao and Zhou Bing came probably didn't have anything good, so let's choose another one.

Choosing the middle road, Ding Xuan walked over quickly, it was a tall building, the door was carved with a handsome young man, the upper half of his body was bare, and his delicate body was entangled by beautiful vines.

Ding Xuan touched the door. The door opened quietly, and the moment the door was opened, Ding Xuan was so frightened that she almost screamed, and at the last moment she covered her mouth, feeling so dangerous.

Inside the building's lobby lies a monster, covered in black scales. But it was like a leopard, with a pair of elephant ears and two wild boar-like tusks that hung up from the depths on both sides of the mouth, as big as a hill, and it was very frightening.

Eighth-Order Great Perfection Beast!

The monster was asleep, snoring deafeningly. On both sides of the hall, a bookshelf is inlaid on each wall, filled with a variety of books.

She slowed down. Gently approaching one of the bookshelves, there were a variety of books, and she gently pulled out one, the words on it were very unfamiliar, some like cuneiform, some like ancient Egyptian, very obscure, fortunately the trialists have been systematically strengthened. Gained the function of language and text reading, and can read any text.

Alchemy. Volume 1!

This book is actually "Alchemy". She opened it and looked at it, the alchemy in this book was not the same as the "General Outline of Refining" she had studied, it was another civilization's refining method, which was based on magnetism. Its weapons, equipment, and even the tools used for daily clothing, food, shelter and transportation are all driven by magnetic force, while the "General Outline of Refinery" that Ding Xuan studied before is driven by spiritual power. Including the Alien Beast Gem, it is also a kind of spiritual power.

And magnetic force and spiritual power, in the final analysis, can be regarded as a kind of energy. But magnetism comes from magnets, and there are countless magnets on the earth. Countless magnetic weapons can be crafted, and even technology will be a big step forward.

It is estimated that these books are the essence of civilization in this ancient ruin, representing all the achievements of this city.

She immediately quietly put the book into the jade space, and then glanced at the monster, it was still sleeping, secretly relieved, and began to search for all kinds of books, refining, alchemy, medicine, science and technology, culture, and even some of the methods of people in ancient times to practice the body, used in various martial arts now, it is a big progress.

"Smack." Because she was too excited, Ding Xuan didn't pay attention, and a book slipped off the bookshelf and hit the ground, making a dull sound.

Her heart immediately rose to her throat, and she secretly turned her head to glance at the monster, and when she saw that it didn't react, she breathed a long sigh of relief, and was about to continue searching, when suddenly the light in front of her dimmed, her face changed suddenly, her body reacted faster than her spirit, and she instinctively jumped up, and a Nine Heavens Divine Thunder slashed directly at the monster's head.

Boom -

The earth-shattering loud sound exploded in the hall, Ding Xuan borrowed his strength on the arched roof beam, and landed steadily on the ground, the light of the divine thunder dissipated, and the monster let out an earth-shattering roar.

Ding Xuan's face was as white as paper, she struck with all her strength, but it only scorched a piece of its head, how strong this monster's body was!

No matter, run!

Ding Xuan exerted all the strength of his body, and even took out a bottle of purple speed potion, poured it down, and ran away.

"Roar-" With the roar of the monster, a huge flame roared, Ding Xuan just rushed out from behind the building, who would have thought that there was a river below, the river was rippling with blue light, and it was bubbling with bursts of cold air.

The flames roared overhead, Ding Xuan gritted his teeth, and rushed into the river, the monster seemed to be unable to leave the hall where the books were stored, standing on a high place and staring at the river below with hatred, and finally turned back unwillingly, and continued to sleep.

When Ding Xuan fell into the river, what she felt could only be described in one word: extreme cold.

The river was so cold that she was determined to resist it, but she still felt the cold penetrate into her bones, and every bone was frozen and painful.

Her autumn water flow firefly suit had been broken before, she had never found the material to repair it, and now she had no ice defense equipment, her whole body was frozen, and she couldn't even move her fingers.

Wrong! She thought to herself, this is not ordinary cold, this is a kind of yin cold, it is the cold air emitted by something of yin nature, so even if it is so cold, this river is not frozen.

But there is certainly no living creature in the river, and all living creatures freeze instantly when they enter it, even the hardy fish that live in the Arctic and Antarctic all year round.

Ding Xuan had to decide to protect his body one day, so he was able to persevere until now, but it was limited to this, he sank stiffly to the bottom of the river. Looking at the glimmer of light on the surface of the river, she suddenly wanted to see Xue Helei again, she hadn't said to him that she loved him, she hadn't said that she wanted to be with him for the rest of her life, if she was going to die, before she died, let her shake his hand.

She sighed helplessly, and then her consciousness sank into darkness.

I don't know how long it took, but she felt that her body was warm, as if she was soaking in a warm hot spring, every meridian was nourished, and her body was extremely comfortable.

In a daze, she reached out and felt two thick pectoral muscles, his skin was like a velvet soldering iron, so she couldn't help but touch two more handfuls. Then, she heard a patient murmur.

"Ah Lei?" She arched into his arms, raised her head and leaned to his neck, "Ah Lei, is it morning?" ”

"Sister Xuan, wake up, it's me." A hand reached over and patted her cheek gently, she frowned, how wrong was this voice, struggling to wake up from her daze and see a handsome face.

"Yan Yuan?" She gasped sharply and jumped up, only to find that she was naked, and Yan Yuan was wearing nothing.

Her mind was blank, she looked around, and found that her clothes were thrown aside, so she rushed over and grabbed them and hurriedly put them on: "You, you ......" She originally wanted to scold Yan Yuan, but when she thought of Albert's incident last time, she suddenly lost her temper again, what if she took the initiative?

"Sister Xuan, don't be nervous." Yan Yuan methodically began to dress one by one, "Your whole body is frozen, I will use this method to transmit true qi into your body to help you warm up." Seeing that her face was flushed, she quickly explained, "Don't get me wrong, nothing happened to us." ”

"Does this need to be the case for teleporting true qi?" Ding Xuan asked with a red face.

"When I found you in the river, your meridians were frozen and solidified, and the true qi could not flow smoothly, so I needed to directly contact my three dantians and your three dantians, as well as my limbs, in order to transport the true qi into it." Yan Yuan said frankly, "To be honest, Sister Xuan, your body is really strong, if you change to someone else, your meridians will be frozen and you will definitely die no longer dead, but you can wake up so quickly." ”

When Ding Xuan heard this, she sank her divine sense into her body to check, although the meridians were not broken, they were still damaged, and I am afraid it would take a long time to fully recover, and now her strength is only one-third of what she used to be.

"Where is this?" She looked around, and it seemed to be some kind of palace, with a beautifully made clay chandelier hanging overhead, but no wires could be seen.

Magnetic light!

The surrounding walls are painted with colorful pictures of the world in this ancient city, as well as heroic hymns, painted in some era, and the colors are as bright as ever.

"This is the tomb of the King of Atlantis." Yan Yuan said, "This city is Atlantis, which sank in ancient times. ”

Ding Xuan was stunned for a moment: "Isn't Atlantis far away in the Atlantic, how could it suddenly appear in the mountains of Yun Province?" ”

Yan Yuan smiled mysteriously: "Who said this is in the mountains of Yun Province?" ”

Ding Xuan's heart chuckled, the size of the misty forest he saw from the satellite was only a dozen kilometers, and the size of this secret realm was unknown. If you think about it, that fog may just be a passage to the secret realm, and as for this secret realm, it may be anywhere on the earth, or even not on the earth.

Ding Xuan looked at the paintings on the wall, in the first painting about the origin of Atlantis, there was a round object in the sky, a figure appeared from the round object, and the aborigines all lay on the ground and knelt down. The painting in the back tells the story of how this man educated the aborigines, helped the aborigines build a city-state, practiced physical arts, and developed science and technology, and Atlantis was once very prosperous. Years later, the first king of Atlantis left in a flying machine, promising to come and take the natives to heaven, where they have been waiting for him to return. (To be continued......)
