"That's it?" Dawn was stunned for a moment before saying, "No problem." According to the previous agreement, Jiufeng Mountain will share the treasures found in this ruin with the official. Since these books and materials are left over from prehistoric civilizations, they are part of the agreement. Even if you don't mention it, after this knowledge is translated, Jiufeng Mountain is qualified to consult and possess. ”

"That's good." Luo Yun nodded.

These days, Liming's status in the government has been promoted again and again because he is responsible for the excavation of the remains of prehistoric civilizations. Here, what he said and what he made made were recognized by the government after he went out.

Besides, Luo Yun is not afraid that they will not recognize it.

Opening the dimensional bag, Luo Yun took out a large number of Yuan Spirit Stones from it.

"How do I use these?" Dawn picked up a piece of Yuan Ling Stone and studied it over and over in his hand.

No matter how you look at it, it's like an ordinary stone, and you don't see anything like an interface.

Taking a step back, even if the stones have interfaces on them, the 'computers' in the ruins have no physical ...... At least people haven't found where its chassis is, like plugging in a 'USB flash drive', they can't plug it in......

"It's easy to use." Luo Yun taught Liming and the scientists the use of the Yuan Spirit Stone.

After the scientists memorized the usage, they rehearsed several times with the Yuan Ling Stone, and after determining that they had mastered the method, they did not rush to 'download' the books and materials, but numbered these Yuan Ling Stones one by one, and numbered the tall bookshelves in the ruins at the same time, and finally used the Yuan Ling Stone to download and save the books on the corresponding numbered bookshelves.

This thing looks simple, but it is very time-consuming to actually do.

Because there are so many books and materials in the ruins!

Of course, there is another reason, that is, although everyone has learned the method of using the Yuan Spirit Stone, they are not proficient, so they have been delayed for some time. However, with the increasing number of 'downloaded' book materials, everyone is becoming more and more familiar with the use of Yuan Ling Stone. The speed is also gradually accelerating.

In the blink of an eye, another seven days passed.

After seven days of busyness, all the books and materials left in the ruins of the prehistoric civilization were copied into the Yuan Spirit Stone.

Just after the last book turned into a point of light and flew into the Yuan Ling Stone, in the ruins, the tall bookshelves suddenly collapsed, disintegrated, and dissipated.

The cave, which had been illuminated by the light emitted by the books, immediately plunged into darkness.

This scene came very suddenly, so that people did not react at all in the process. By the time they reacted, the bookshelves and the collection of books had all turned into specks of light and then disappeared.

"What happened?"

"How did this 'library' left over from a prehistoric civilization be destroyed?"

"Is there an enemy attacking? Is it an extraterritorial demon? Or an unknown creature hiding in a cave? ”

After a brief moment of astonishment, the people came to their senses, exclaimed and asked questions, activated the lights, and looked around vigilantly.

Even Dawn wondered if an extraterritorial heavenly demon had infiltrated here and destroyed the library left by the prehistoric civilization, and hurriedly shouted: "Prepare to fight!" No matter how much sacrifice you make, you must ensure the safety of the scientist and the Yuan Spirit Stone! Make sure they can get out of here without any problems! ”

Luo Yun was also taken aback by this sudden situation.

He immediately released his spiritual sense and explored the surroundings, but he did not find the breath of the extraterritorial heavenly demon, nor did he find any powerful unknown creatures in the vicinity. Immediately afterward, he gave the spirit sense access to the 'computer' in the ruins, and then learned the truth of the incident.

After sighing lightly, Luo Yun said: "Don't be nervous, it's not that an enemy is coming, but the 'computer' in the ruins, after completing its real name, self-destructed." ”

"Self-destructed?"

Everyone was stunned when they heard this.

For Luo Yun's words, they still believe it very much. Immediately, many people recovered from the panic. But the soldiers and the cultivators of the Security Bureau were still highly vigilant and watched around.

"Why did it self-destruct?" A scientist asked, puzzled.

"I don't know." Luo Yun shook his head, "Perhaps, the survivors of the prehistoric civilization had already set this command for this 'computer' when they left it." Rather than being destroyed by extraterritorial heavenly demons, it is better to self-destruct. ”

Another scientist asked, "How does this 'computer' determine that we are not extraterritorial heavenly demons?" Does it still have judgment and intelligence? ”

Luo Yun shook his head and said, "I don't know about this, maybe it has a way of judging, right?" After all, extraterrestrial heavenly demons and humans, although they are similar in many ways. But there are a few things that are not quite the same...... The most important thing is that we human beings, in a sense, are the lives created by prehistoric civilizations! In this 'computer', perhaps, there is also our genetic data. ”

The scientists said thoughtfully: "It's not impossible, didn't we see the genetic map of human beings when we deciphered the metal door before?" ”

Luo Yun swept his eyes and fell back into the dark cave, and sighed: "This knowledge can be regarded as a legacy given to us by the 'parents' of mankind. ”

Everyone nodded in unison, and then bowed deeply towards the cave together.

Thanks to the gift of prehistoric civilizations.

Luo Yun also bowed and said, "Your civilization has been destroyed by the Extraterritorial Heavenly Demon. As your heirs, we will pass on your civilization in another form. Knowledge continues, and the flame is never extinguished! ”

Then, he turned around and said to Liming, "Take the Yuan Spirit Stone, let's go." ”

"Take the Yuan Spirit Stone and get out of here!" Dawn immediately conveyed this order.

The team was quickly disengaged.

Unlike when they came, now, the size of the team, the number of people, and all kinds of equipment are much stronger than when Luo Yun and the others first came to explore.

The procession marched towards the cracks in the ground.

Luo Yun floated in mid-air, condescending, protecting the team.

However, there was no danger along the way.

After arriving near the cracks, the communication equipment returned to normal, and Dawn used them to contact Shi Peng in the frontline camp.

Soon, there was a loud noise, and the surrounding ice and snow were shaken off.

Several lifting platforms appeared in front of everyone's eyes.

It turned out that in the past few months, Shi Peng and others in the front-line base have not been idle. In addition to transporting scientists and various equipment to the cave, several lifting platforms were built here to facilitate the transportation of personnel and equipment.

Every day, dedicated technicians come to clear the snow and check the situation to make sure they are ready for use.
