"This is the writing on the wall of that cave, look at the handwriting, that is, the level of elementary school students. Pen & Fun & Pavilion www.biquge.info" Professor Yang took out a stack from the pile of photos and handed it to Ling Ke. He laughed and said, "It's just a joke that God played on us!" ”

Ling Ke looked through it and saw that these photos were taken in parts, and they were composed of twenty wall photos that together constituted the entire text content of the entire cave wall.

He saw that one of the photos had the word "Lingke" in its handwriting, and he felt familiar. And he stretched out his hand, and said,

"Professor Yang, please give me paper and pen."

Without waiting for Professor Yang to make a move, the little girl happily ran to the bookcase in front of the window, brought a brush and a book inkstone, put them in Banlingke's hand, and said:

"Little brother, here you go."

Ling Ke looked at the brush and inkstone for the first time, smiled, and shook his head.

"Yuange, you are in the first elementary school in Yichun, and your brother Lingke is in the second elementary school. He's in the first grade of primary school like you, and he doesn't use a brush. ”

"I'm sorry." Yuan Ge stuck out her tongue, shook her pigtails, went out of the house, found a pencil from another children's room of her own, and sent it over.

"Little brother, I'm so sorry to make you 'embarrassed'." Yuange's words are very jerky, which makes everyone laugh. Even Lu Ge, who was hiding on the side, laughed like a foreign devil watching a play.

Ling Ke took the pencil and smiled at Yuan Ge and said, "I don't blame you, I'm stupid." Then he wrote two words on the blank paper: 'Lingke'.

He took the photo and compared it with the handwriting that had just fallen on the paper, and said, "It's a bit like that!" ”

Professor Yang took out a magnifying glass, put the handwriting on the paper close to the word Ling Ke on the Zhao tablet, observed it carefully, and exclaimed in a low voice: "Yes, it's the same handwriting!" ”

Ling Ke hurriedly copied the magnifying glass from Professor Yang's hand, and after comparing it through the lens, he was stunned.

"What's wrong, isn't it just writing two words? What's all the fuss! Rugo leaned forward and asked, a little unimpressed.

"Rugo, it seems that in a few days, we have to complete a mission." Ling Ke said.

"What task?"

"Go to your world and find this cave. Let me see, this is supposed to be the place where your father came out of hibernation 5 million years ago. ”

"What are you looking for?"

"I'm going to see if there's any of these words on the cave wall, and if not, I'm going to have to write them so that this cause and effect relationship can be formed."

"What if you don't write?" Rugo had no idea.

"That would offend the gods!" Ling Ke originally wanted to talk about God, and wanted to tell him more about the paradox of cause and effect, but he felt that using the concept of gods was more intimidating to him.

Sure enough, when Rugo heard this, he immediately squinted his eyes and folded his hands in front of his chest.

Professor Yang saw that Ling Ke and an invisible being beside him had finished the ink, so he took out another piece of rice paper, on which Juanxiu's words were densely written in block letters.

"This is what I transcribed based on the photos in the cave. - I've corrected the typo. Professor Yang said to Ling Ke, a slight smile on his lips.

"Professor Yang, my typo has been corrected, but what's going on with these circles?" Ling Ke pointed to the rice paper spread out on the table, and found that between the lines, six or seven out of ten were not words, but were replaced by circles.

"Oh, it's not your fault, it's only the time that goes by. Five million years is enough to perish a short-lived star, and the handwriting on the walls of this cave is even more reasonable. ”

"What should I do?" Ling Ke's curiosity was dispelled at once, and he was anxious to understand the content of the handwriting on the rice paper.

"Don't be discouraged just yet. Fortunately, I still have a chip here, which is the origin of the frozen man in the sarcophagus inside. Through the results of decades of decoding, and comparing it with the content on the cave wall, the tip of the iceberg in this huge mystery has finally been revealed. ”

"Then, Professor Yang, you can reveal the secret." Ling Ke's gaze returned to an excited look.

"Of course. I've been waiting for thirty years. Professor Yang opened a computer on his desk.

"Grandma, I'm going to play Super Mario." Yuan Ge snatched the mouse and said as she jumped.

"Yuange, I have something to do with your little brother, and you can play again in a while." Professor Yang gently pulled away the little girl's reluctantly retracted hand. She said, "Hurry up, it's even more important to play Super Mario." ”

Professor Yang opened an electronic file and said: "Unfortunately, only part of the data is binary, and the rest of the code is written in quantum mode, and can only be decoded after the invention of quantum computers." ”

"Why not all binary encoding, what's the point of secrecy?" Ling Ke asked puzzled.

Professor Yang glanced at Ling Ke's right palm and said, "If my guess is correct, just like the chip in your palm, it is gradually revealing its function. Therefore, it can be concluded that the content in the chip is also gradually decrypted with the development of human civilization. ”

After a dense stream of numbers flashed across the computer screen, a large section of Chinese characters was revealed. Ling Ke took a closer look, he had only studied elementary school for a few days, and he seemed to think that the decoding of Chinese characters through vision and then in the palm of his hand was too slow, so he simply pasted it directly on the screen with the palm of his hand and read it quickly.

Time is pushed back 300 million years. Earth has been attacked by aliens. As the head of the United Earth government, Sue Zhankun fought a desperate battle with the alien leader Umakong and his vast space fleet, but eventually lost the country and led the Earth's armed forces to flee into deep space.

Fleeing from the earth with him, there is also the "Holy Maiden" who is the representative of the religious beliefs of the earthlings. However, a small number of humans from these prehistoric civilizations remained on Earth, and they were armed forces led by Yan Qiong, who were rebels against the rule of Umakor, so they were sentenced to life imprisonment by the international tribunal, frozen in sarcophagi and buried in the ground.

It is important to note that in the later stages of the war, the earthlings finally knew the true purpose of Uma Kong's invasion of the earth. To be precise, he is not an alien, but an intelligent life in the outer universe, on the surface, the physical characteristics are no different from humans, but the body can be inhabited by poisonous snakes, so he is called a mutant by the earthlings.

They did not come to Earth with the intention of occupying, but only for one person, the captive of the Holy Maiden, to save their dying universe.

When Ling Ke read this and was about to explore the reason, a garbled text appeared on the computer screen.

"What does the fate of their universe have to do with the Holy Maiden's Shadow?" Ling Ke asked Professor Yang for help.

"That's what I've been thinking about all these years. The answer is up to you. ――Do you know who you are now? ”

"yes, I see. I am Yan Qiong, the leader of the rebels of the prehistoric human government, who was pressed under the stratum by Uma for 300 million years, and Rugo's father is my subordinate, who woke up 5 million years ago, and I saw the light of day again in the twentieth century. Ling Ke knew everything about Professor Yang, and from her eyes, she saw another side of human beings, that is, persistence, clarity and sincerity.

"Huh? Ling Ke, you are too arrogant, why did you become my father's leader? Rugo was a little reluctant.

"It's more than that. I think that at all stages of the history of the earth, there will be my subordinates who have awakened in different eras, and your father is only one of them. If you don't believe me, you can see what is written on this rice paper. Ling Ke said thoughtfully.

Rugo squeezed over, overwhelmed by the mass of square words, and Ling Ke helped him read it in his synaesthesia.

Rugo's father was discovered during a burrow digging in a northeastern ape, and he became one of the Homo erectus. Because of his courage and good fighting, he repeatedly made meritorious achievements in battles with other races, and was favored by Rugo's mother and married to him, and later gave birth to Rugo.

Later, he was murdered by the mutant leader Zhan Halberd and the traitors among the Homo erectus. And Puke wants to cut down the grass and eradicate the roots, and kill Rugo. His mother had to send him to a neighboring tribe for a few years to take refuge, and only then did he return to the clan after the turmoil subsided.

Later, it is the description of Ling Ke and Rugo who establish synaesthesia in order to grab a piece of ore, and Ling Ke teaches him to use fire to defend against enemies. and detailed the life experience of Ling Ke. His predecessor was Yan Qiong, a leader of government rebels in a prehistoric civilization, and he belonged to the same frozen people as Rugo's father. Together with the frozen people of all eras, they shoulder a great and arduous task, that is, to save the cosmic civilization, protect the Holy Maiden, and repel the attack of the Outer Universe people.

Next, there was a string of ellipses, and only the illegible words remained on the broken cave walls.

"What's next on the cave wall?" Rugo asked.

"The words on the walls of this cave seem to be mottled and peeled, but let me see that there is a mystery hidden in it. What hasn't happened yet, isn't shown on it, and needs me to write it down with you. ”

When Rugo heard this, he touched the top of his head as if he didn't understand, and said, "What worries me most now is that someone will drill a hole out of me here, and I don't know when it will happen." Can you escape this catastrophe? ”

"I think I can. Eventually, one day, I'm going to write this future-defining text on the cave wall, and when the time comes, I'll just skip your fate? ”

These words made Lu Ge confused, and he pondered for a while before he came to his senses: "This bad luck, if you don't write it, may not happen." In my opinion, the most important thing is to be more vigilant against mutants harming me. ”
