After eating, Qi said that he would take turns to keep vigil, and Wen Ding said that he would come first, but he deliberately did not wake Qi, so that he slept until dawn.

Wen Ding took Qi to the place where the metal was found last night, it was still buried deep in the earth, waiting for Wen Ding to arrive.

"Will you have a blue sun today?"

"I don't know, but I'll feel it in advance."

The two of them began to dig down the protruding piece of iron, and in Kai's baggage was a wooden hoe, the hoe was made of copper, and like the first metal element used by humans in the early days, the metal used here was still copper, the easiest metal to refine.

After digging for a long time, I didn't see this thing completely exposed, and I could vaguely see that it was a curved metal piece, as if the chestnut was split in half vertically from the middle.

After Wen Ding stood firm, he grabbed it with both hands and pulled it hard, the iron piece was pulled out of the ground, and Wen Ding fell backwards heavily.

Getting up from the pit he had dug, Wen Ding looked at the metal plate in his hand that reflected the sunlight, which was taller than Wen Ding, Wen Ding remembered that his height was about one meter ninety-five, and this thing should be two meters long.

The strange thing is that although this metal plate is large, it is not heavy, it is white all over, and it is very smooth, but Wen Ding grasps the edge and can lift it with only one hand.

Cracks in the corners indicate that this is part of the remains of an object, and that there are many of these metal pieces buried underground.

Kai tried to take it, and he picked it up easily, beating it with a hoe, but he couldn't leave a trace.

"Aluminum?" Wending said suspiciously, light weight, high hardness, very consistent with the properties of aluminum alloy.

Wen Ding suddenly realized that this should be an extremely significant discovery, which was obviously not the technology of this world.

Qi naturally recognized that this thing was by no means something that could be made in the tribe, so he began to dig again, and if all the pieces were put together, it should be possible to restore it to an object.

With Qi's excavation, more and more glass slags and metal pieces were excavated, all of which were of different shapes and sizes, and the one that Wending pulled out was the largest one at present.

It wasn't until the moon lifted off that all the debris was excavated.

The piled up parts were like a small mountain, and Wen Ding saw that there were screws, nuts, and wires inside...... It's all something I know.

It's a pity that many things have been deformed, even if they want to splic, the two of them can't start, this is obviously some kind of precision instrument, and the white thing in Wen Ding's hand is the protective shell.

"Do you know what this is?" Kai asked.

"I can't see it, it's terrible." Wen Ding replied, but at the same time, in Wen Ding's mind, everything in front of him moved, looking for the vacancy that he could fill, and put together a tree, a house, a well, and a bridge......

Qi saw that Wen Ding was thinking, so he stood aside silently, waiting for Wen Ding.

In my mind, I don't know how many times I simulated disassembling and reorganizing, and in the end I only came up with two possible things - this is a small house, if you want to use all the materials, glass can be used as windows, and in my hand is the door.

Another possibility is that the aircraft that are very common in the world of Wending, this kind of thing with an external color looks some years old, and there is no rust, much like alumina, which is the main material for aircraft and rockets, and of course, high-strength plastics, but alumina is easier to make.

Wen Ding told Qi about these two possible things, and after Qi listened, he suddenly remembered that he had told himself that Wen Ding had fallen from the sky, and at that time, Wen Ding was riding on a vehicle that shattered into wreckage after landing.

"Could this be a spaceship?"

"A spaceship is a flying machine."

"The day we brought you back, there was a pile of wreckage around you, and although I haven't seen it, could it be the same thing you used when you came? Because our tribe doesn't make these little parts. Qi held a screw in his hand and spun the nut.

"I don't remember, but if it is, then whose flying machine is this?" Wen Ding pondered and said, "Are there other foreigners like me?" Wu An? ”

"Wu An is a native of his own people, at least the legend is like this."

"Who could that be?"

Kai didn't answer, he also wanted to know whose flying machine it was, this piece of wreckage was buried deep underground, it seemed that it had been some years, if there was another person like Wen Ding, then where was he, or her? And if someone came before Wending, then he said she was the prophesied warrior?

Wen Ding thought for a moment and grabbed the piece of metal: "Let's go back to the camp first." ”

This is Qi suddenly had a strange feeling, and said loudly: "The blue sun is coming!" ”

"But it's night, where does the night come from......" Before Wen Ding could finish speaking, the moon flashed twice, and then a blue sun took the place of the moon, shining on the earth.

Before Wen Ding could react, the metal piece in his hand had already been snatched away by Qi and covered himself.

The surroundings were as bright as day, everything was illuminated, snakes and insects were running around, and there was an unknown wail in the distance. The wind cried, and all the things in the darkness were revealed, and everything was out of control under the blue sun.

Wen Ding stood in place, squinting his eyes and staring directly at the sun.

After about half an hour, the blue sun disappeared, still for a moment, and the night was lifted by the blue sun, breaking in like a robber, and some were lifted up, leaving like a thief.

Night fell again, and Qi stood up: "This is indeed rare, but sometimes there is a blue sun at night, so in the tribe, we will pull down the connector at night to prevent the reflected sunlight from shining after falling asleep." ”

"I can't see it at all, it's too fast." Wen Ding said that he still didn't blink this time, but he still didn't see clearly, the sun and the moon, the two are simply seamless.

"If it was so easy to see through, Wu An would have led us to overcome the sun a long time ago."

Qi didn't mean to be sarcastic, Wen Ding could also hear it, indeed, the previous saints of this tribe couldn't see through it, he had only been here for less than a year, how could he see the mystery of this world at a glance?

"Let's go back to camp." Wending proposed.

Qi followed Wen Ding, holding the piece of metal in his hand.

"Why are you still carrying it?" Wen Ding saw that Qi had been holding the piece of metal that he had picked up, and he was reluctant to let go like his childhood Xinhai holding a doll.

"Do you know why wood is not affected by the rain, but we don't use wood as umbrellas? It's because it's too heavy and not conducive to carrying, the thing you found can isolate the sun, and it's very light, about the same weight as a bamboo umbrella, and it hasn't been corroded by rain for so long, which proves that it is not affected by raindrops and can completely replace bamboo umbrellas. Qizheng took out a bamboo umbrella from his baggage and threw it on the ground, "I have this, I don't need these umbrellas anymore, leave them here for the next team to use." ”

Wen Ding watched Qi take out five or six umbrellas, and his baggage was suddenly empty.

"When we get back to the cave, I'll tell Elder Bing that there is this kind of thing here, and ask him to send someone to bring all the pieces of iron back."

Qi was obviously a little excited, like a child who got the New Year's money, and almost jumped up.

"So what do we do next?"

"The exploration in the west has been put on hold due to the river, so there will be no follow-up team, but if we find a way to cross it this time, then the umbrella I left will be useful, let's continue walking, find the river you want to see, and then try to find a way to cross, and draw a new map, build a camp, broaden the scope of our exploration, and maybe find a new tribe......"

"Why did you just wake up and dream again?" Wen Ding asked teasingly.

"It's a reasonable assumption that assuming we can find a way out, it opens up more possibilities for the future."

"Alright then, I'm kidding, when is it going to go?"

"Early tomorrow morning."

"Okay, go to sleep, but looking at your appearance, I guess I can't sleep."

Kai nodded and fell asleep on the metal piece that looked like half a chestnut shell, it really looked a bit like a pillow, with a bulge in the middle.

Wen Ding pillowed his hand, lying on his side with his back to Qi, and was about to fall asleep, when he suddenly reacted that Qi didn't say anything about the vigil.

"As for being so excited?" Wen Ding sat up and slowly added grass to the fire, which was very resistant to burning, like a wooden block.

I don't know if it's because I'm too tired or because of Qi's snoring, Wen Ding felt that his eyelids were very heavy, and after holding on for a while, he closed his eyes and fell asleep.

At this time, a memory quietly appeared, turning into a dream to fill the vacancy of Wending's memory.

......

"To save them? And then what? Wen Ding asked ignorantly, his father's words were a bit informative.

"But I couldn't find the entrance anyway, I bought a ticket and flew to Australia, but no one knew about the Celestial Tomb there, only the homeless and the drunks in the bars were willing to listen to my stories, because these things were more like gibberish."

"Later, I met Li Gui, it's that old man, heh, he's still alive now."

"I met him in the bar, and I was telling the story of the Celestial Tomb at that time, and he suddenly rushed up and said that he knew about the Celestial Tomb and that he had just come out of it, so I pulled him out of the bar, and he said that he knew something about the Celestial Tomb and asked me to go home with him."

"His house is full of all kinds of experimental instruments, as well as mountains of drawings, he showed me a painting like a child's graffiti, a very flat black oval is drawn in the middle of a leather ball, he said that there is a black hole in the middle of the earth now, but for unknown reasons, it has not swallowed the surrounding matter, but has always existed in the center of the earth, and will have an external attraction, coupled with the gravitational pull of the earth itself, more and more people on the earth have spondylosis."

"He said that the tomb of heaven is in a black hole, and I said that you fart, because I drifted from the sea, and I didn't float out of a black hole, if I can physically get out of the black hole, the future Nobel Prize will be all mine, it's a medical miracle."

"He said he had a way to prove it, so he shot a rocket into the sky, okay, I admit that he is still quite rich, in stark contrast to a poor scientist like me, and then let me look at the time and the speedometer by myself, let me do the math myself, but it has reached the first cosmic speed, but the rocket still hasn't been able to fly out of the earth."

"Later, I checked, all the equipment was not manipulated, and the gravitational pull of the earth was stronger, but no one found out, and we later changed to different regions, and we got almost the same results."

"But I did drift from the sea, and he said he didn't know, but he had a way to get back to the Celestial Tomb."

"I thought he was going to dig an ultra-deep well like a certain country before, but he told me that it was to launch a spaceship into the sky, and I just wanted to scold him, but he said that it was told to him by the manager of the Heavenly Tomb, and then I compared the Heavenly Tomb with him in my impression, and found that it didn't match at all, but we were all sure that we saw it, so there was only one possibility, there were two Heavenly Tombs."

"No matter which one I go, I need to go, because I want to take advantage of it, but if I want to go, I need to be a young man, but he doesn't know why."

"Later, he said that I really wanted to go, so he simulated it with an instrument, and then he put me into a pool, which was supposed to be the deep-sea liquid used in the high-speed operation of the spaceship, used to balance the pressure, and then inserted two jars, and he told me that my body was not suitable for going to the Heavenly Tomb, saying that my body was too bad, and there were still problems with my lungs, and if I wanted to go, I didn't dare to guarantee that I would live, and at that time I always wanted to take someone else with me, so I asked all the people I could think of to go to the test, and no one met the standard, As a result, he saw you who were only more than two years old, so he took you to the test, and you passed, of course I didn't agree with you to go, the old can't die the young, so he insisted that he should go, in order to run in the indicators, I slowly became haggard. ”

"Alas, it's a pity that I have a handsome face, and I'm telling you now because, I'm going to go to the Heavenly Tomb, not because I don't want you, it's because I have to." Father said a little hesitantly.

Wen Ding obviously heard that he didn't finish speaking, if it was just to save people, his father would never go, but Wen Ding felt that his father had his own reasons, so he didn't ask too much.

"So what? You tell me you're my father, and then my father is leaving? ”

"I can't help it, oh yes." The father's face was a little flustered, "Don't ask again, I'm going anyway." ”

"How long will it take to be back?"

"Sixteen hundred years from now."

“......”

Father's expression was obviously not joking, Wen Ding was a little overwhelmed, but he still pretended to be calm: "I... I've long been used to being alone, and I'm used to it in an orphanage. ”

"Hmm" the father no longer smiled, and his voice was a little low and choked.

"But come back early if you can, 1,600 years is too long, I think a year and six months are about the same." Wen Ding said expressionlessly, "I'll wait for you." ”

"yes, okay." Father's eyes were a little red, and he turned around and said, "Let's go down, we can have another drink." ”

......

The picture changed suddenly, Wen Ding was in a small spaceship, waiting for the final ignition, Xinhai was beside Wen Ding, holding Wen Ding's hand, and Li Gui was standing in front of the console.

The three of them looked at the middle-aged man in the launch capsule together, he was very thin, and his hair was already a little gray.

Through the glass, his father looked at Wen Ding: "It's no problem, you see, I'm fine now." ”

The father tried to wave his hand, but his hand was fixed to the seat and his neck was fixed, and he could only blink.

"Sorry, these fixations are necessary to prevent you from breaking bones." Li Gui spoke to his father through the microphone on the console, and his father shouted loudly: "I understand the small problem. ”

Then he turned his head to look at Wen Ding: "I will come back as soon as possible." ”

Wen Ding nodded, Xinhai grabbed Wen Ding's arm beside him, his eyes widened, looking at his father-in-law.

"Xinhai will help me take care of this kid in the future! , my son of Wu An, you can't learn badly, if you learn badly, you will beat him, he will not dare to fight back against you! The father said with a smile, but his voice was a little choked, "You have grown up together, I believe you can go far, far away, Wen Ding don't give up on other girls!" At least... It's farther than me and Wen Xin..."

Wen Xin is Wen Ding's mother, and Wen Ding takes his mother's surname.

"Come on, good son, hehe, call dad again."

Wen Ding turned his head and looked at Xinhai: "Come with me?" ”

Xinhai nodded timidly: "Dad... Dad..."

"Dad, come back early, don't wait until your grandchildren are grown up to come back."

Wen Ding felt that his father's state was very strange, as if he was explaining what was going on, which made Wen Ding a little flustered.

Wu An smiled, stopped talking, and nodded.

"Li Gui, it's okay."

The blue liquid suddenly filled the spaceship from nowhere, and the water quickly covered Wu An's ankles, knees, and chests, and when he was about to pass his mouth, Wu An suddenly spoke: "I remember that there is one more thing I haven't said, Wen Ding, Dad..."

The water flooded Wu An's mouth, but Wen Ding saw the shape of the mouth of the next two words - love you.

Daddy loves you.

After saying that, Wu An was relieved, and the deep sea liquid flooded his eyes to the top of his head.

Wen Ding suddenly realized something, and wanted to rush over and grab Li Gui, but his intuition told him that his father would never come back if he went.

Wu An closed his eyes, leaving two lines of tears, but no one could see it, because his whole body had been submerged in the water.

When the fish weeps, only they know.

Wu An didn't dare to open his eyes, he was afraid of exposing the fact that he was crying, and he wanted to leave a strong impression on his son before leaving, so that his son would learn this spirit of himself in the future.

"3-2-1-ignition."

Li Gui pressed the button, and the spaceship slowly lifted off and disappeared into the sky.

"Where's Daddy?" Xinhai asked ignorantly.

"Daddy..... Dad will turn into a star, and when the time comes, he will be back. Wen Ding touched Xinhai's head and repeated as if cheering, "I'll be back..."
