Wow——

The fixed ladder was thrown from the top of the cliff. Konano, Yoshimura and Yamazaka all hung up safety ropes and prepared to use the ladder to climb down into the pit.

It is worth mentioning that perhaps the red smoke in the pyramid has been exhausted. After the sun rises, no more smoke continues to emerge. Throughout the night, it was so condensed that people could not even see clearly in front of them.

The red mist on the road has almost dissipated.

The pungent smell is gone in the air, leaving only the feeling of negative oxygen ions produced by lightning ionizing the air after a thunderstorm.

Even so, the three of them still put on gas masks in their backpacks just in case.

"This cave is too deep." Konno glanced down at the height of more than ten floors. He would definitely be dead if he slipped and fell. Even he, who has been training in the tac team for many years, felt a little guilty.

Because the entrance of the cave is not very big, if you use a helicopter, it will easily scratch the rock wall. Once the propeller scratches, the aircraft will be destroyed and everyone will be killed.

So the tac team chose to climb with a ladder.

It feels a bit like extreme sports rock climbing, but for the tac team members, this is nothing.

"By the way, Beidou rescued someone from down here yesterday? How did he get down and back up again? I remember that there should be no climbing equipment on the Aero."

"Because Beidou has the spirit of not admitting defeat. This is the perseverance of a man!" Yamanaka waved his fist.

No, what does this have to do with perseverance? Is it completely unscientific?

Shanzhong didn't wait for him. After ensuring that the safety rope was fixed, he climbed down the ladder first.

Five minutes later, Yamazaka's feet touched the hollow ground. Followed by Konno and Yoshimura.

Contrary to expectations, the bottom of the cave is very dry, with a structure of weathered sand and gravel, making a rustling sound when you step on it.

The base of the pyramid occupies most of the space, and it looks dark. Although the size can be determined visually from the top of the cave, standing in front of the tower now, I feel even more silent oppression. The contrast between smallness and magnificence, and the ancient time

The heaviness it brings.

Looking around, there is nothing else here, no animals or plants.

"Wait a minute, Konno, don't be too careless!"

Yamanaka shouted, because Konno had already stepped forward and knocked on the wall of the pyramid with his hand.

"Not sure if this thing is dangerous yet!"

"Ah, it doesn't matter. Could it be that this ancient building could be the enemy's base and a super beast pop out? Haha." Konno said with a smile, "But is this really a pyramid? The body of the tower seems to be made of metal. It's so big.

A lump of metal, where did such technology come from in the past?"

Not to mention the past, even now, it is not easy to build such a pure metal building dozens of meters high.

"There are no doors, no windows, not even a gap. Is this thing solid?"

"Let's test its ingredients first."

Yoshimura took out a simple cutter from his backpack, preparing to cut some metal fragments and take them back for analysis. The sound of the cutter echoed in the cave, and the loud noise made Konno and Yamazaka couldn't help but cover their ears. Sparks flew everywhere.

However, after a while, Yoshimura stopped.

"What's going on?"

"What's wrong, Yoshimura."

"The cutter is broken! This metal cannot be cut. Look, there are no traces at all!"

Sure enough, the gears of the cutter had been completely worn out, but not even a trace was left on the walls of the pyramid.

The three of them looked at each other. This metal is probably stronger than any alloy on the earth. And it is not a piece, but such a huge mountain.

There is nothing we can do now, prehistoric civilization, this is too scary. Humans can’t even do sampling?

"The scanning results of the spectral analysis have come out."

Half a day later, Dr. Mu Kaji came to the TAC team headquarters with the analysis report.

Because the pyramid could not be cut and sampled, the base sent Nan Xizi to send a spectrometer for on-site analysis.

"Let me tell you the conclusion first. This is a metal that does not exist on the earth."

"Doesn't exist?"

"Yes, I'm not talking about the formula of the alloy, but the metal element itself is not in the periodic table we know."

"So, I can understand that it comes from outer space?" Captain Long asked.

"It can be said that its physical and chemical properties are very special and cannot be produced naturally on the earth. However, although the pyramid itself cannot be sampled, after investigating the surrounding environment, we found that this ruins indeed have a long history.

.Probably more than ten thousand years."

This is a length of time that humans cannot imagine. Ancient Egypt, the oldest of the four ancient civilizations, can only trace its remains back to more than 7,000 years ago. There was no record of civilization before that, and we can only rely on the unearthed skeletons.

Fossils prove the existence of humans.

"Wait, if I remember correctly, the one recorded in the file was also ten thousand years ago?"

"Yes, in the sealed Omega archives, the Nongmart people recorded in it should have been in a similar era when they were still living on the ground."

"So this is a relic left by the Nongmart people?"

"Maybe, but according to the contact records of the Ultra Guard at that time, there is no record of the Nongmart people building pyramids. Their architectural style is not like this."

The only things that can survive thousands of years in terms of clothing, food, housing and transportation are those buildings, so architectural style can often be used as a symbol to identify civilization.

"So, that means this is another super-ancient civilization?" Captain Long rubbed his chin, feeling a little headache.

What is the history of the earth? What kind of planet was it before humans?

No one can ask. Captain Dragon's mind popped up with the image of a little girl, but he quickly put it aside. Now it is mankind's own problem.

The earth is obviously the homeland of mankind, but mankind still knows too little about it.

Because human history is too short, the evolution of any species will take at least tens of millions of years.

For example, dinosaurs evolved from small dinosaurs like Coelophysis in the Triassic Period to powerful Tyrannosaurus Rex and Triceratops in the Jurassic Period. This evolution took 100 million years.

Until the last extinction in the late Cretaceous period, species called dinosaurs lived on the earth for more than 200 million years.

However, human beings have created today's scientific civilization in just a few thousand years.

It's better to say that you are a nouveau riche, let alone win the lottery jackpot in one night. There is no struggle at all, and it feels as if a large period of time is missing.

"Could it be that the problem is actually us humans?"

For some reason, Captain Long had such an idea in his mind.

The sunlight outside the window was a bit dazzling, and Sakura opened her eyes in a daze.

This is her bedroom. She had been waiting for her father in the living room last night. Although she confirmed from Lingya that her father was indeed fine, she was still worried. Her father should have come back in the middle of the night. At that time, she fell asleep on the sofa in the living room, fascinated.

I was confused and didn’t know how I got back to the room.

Sakura glanced at the alarm clock beside her bed, it was seven o'clock now.

She didn't change into pajamas and was still wearing her school uniform from yesterday. She was a little sticky after sleeping all night, which made her want to take a bath. But if she took a bath now, she would be late for school.

Pushing open the door, Sakura smelled the fragrance coming from the living room. It was the smell of breakfast.

"Dad!"

"Good morning, Sakura."

The kitchen and living room on the first floor are connected. When Sakura went downstairs and walked to the living room, she saw her father frying eggs in the kitchen.

"Sorry, Sakura, I made you worry yesterday. You should go wash up first. Besides, I asked for leave from school for you."

"Are you asking for leave?"

"Yes, I took a day off. You didn't have any rest last night, okay? You can take a nice bath. Your friend is also worried about you and didn't go back so late last night. I originally wanted to keep her here overnight."<

/p>

"My friend?"

"Yes, when I came home last night, wasn't she with you? You should thank her properly."

Sakura then remembered that it seemed to be true. Ling also came to her house late last night and told her that she had confirmed her father's safety.

She was still very anxious at first, but with Lingya accompanying her, she gradually relaxed and fell asleep on the sofa.

Ah, it's so embarrassing. It's so rude of me to leave guests here but I fell asleep.

Tenglong came home after 1 o'clock in the morning. At that time, the girl named Reiya was still with Sakura. Although he offered to stay overnight, the Kinomoto family did not have any spare guest rooms, so he took the initiative to let others sleep with Sakura.

The room is indeed a bit disrespectful.

Moreover, the other party said that there was a private car waiting, so Tenglong did not force it.

The child of the famous Oshima family in Tokyo is closer than expected. Regardless of his family background, it is really a blessing for Sakura to make such enthusiastic friends. Tenglong is also glad that he agreed to let Sakura participate in the TV series.

choice.

Sakura is much more cheerful now than before.

"Dad."

"Huh? What's wrong, Sakura."
