"You're awake..." Hao Zhigang came back from the boiling water room with a thermos. He saw song Xiaojia sitting up from the bed vaguely. He hurried over, put the thermos on the head of the hospital bed and helped her lean against the head of the bed.

"I... how did I sleep? Where is this? The hospital?" Song Xiaojia looked around the ward. Although it was clean, it was a little old. The white paint of the old iron shelf hospital bed and the bedside railing had peeled off. The white wall in the ward was painted with a circle of green dados, which looked very rustic.

"You've been in a coma for several days..." Hao Zhi sat down, picked up an apple from the head of the bed and cut it with a knife.

Jia Jia scratched her scalp with her thumb. She couldn't remember what had happened before. A piece of her memory was empty, as if she had been picked out by life.

"Let's go down to the cave to explore, and then it collapsed before long... Fortunately, I had the ability to bring everyone out!" Hao Zhi cut off a peeled apple and stabbed it with the tip of a knife and handed it to Jiajia.

"Oh..." Song Xiaojia took a bite and said, "that's strange. I don't remember at all!"

"Don't think about it if you can't remember it. Anyway, everyone is fine. OK!"

"Yes!" Jiajia continued to play her silly nature, never being more serious with herself. If she couldn't remember, she wouldn't think about it. It doesn't matter. As long as Hao Zhi is still around and feeding herself apples, it's better than anything.

"What about them, professor?" she asked suddenly as if she remembered something.

"The professor woke up yesterday, and there was nothing wrong with his body. Everyone else was still in a coma. He may have been a lot frightened." Hao Zhi replied with a pretentious ease, "Fortunately, you wake up. The professor has taken the first step and brought the Crystal Skull back to the underground palace laboratory. He said he asked me to go back together when you wake up and continue to study the skull. If you're all right, let's go this afternoon."

"Oh..." Jiajia chewed two apples and suddenly his stomach growled. He was unconscious for three or four days. He was only maintained by infusion. He felt that he couldn't stop it, so he whispered to Hao Zhi shyly, "I'm so hungry..."

Hao Zhi looked at Jiajia in front of her and saw her pale little face when she just woke up from a coma. She suddenly felt that if she didn't have the usual domineering female man temperament, she would still be very cute. She leaned against the head of the bed like a sick seedling, soft and weak.

"OK, OK! Snacks!" Hao Zhi clapped his hands and stood up. "What do you want to eat? I told you in this small county. Everything tastes terrible!"

"That's not afraid!" Jiajia lowered her voice, as if afraid that the wall has ears. "Don't you have that ability! Jump, what do you want to eat?"

"I made a song! Boss, you took me as a courier?" Hao Zhi looked unhappy, but sighed, "come on, what do you eat?"

"American hot dog!" Jia Jia narrowed her eyes and giggled mischievously.

Alas! Hao Zhizhao knocked her on the head and waited!

After a few seconds, the brush appeared again, holding a steaming bread with sausage in each hand, taking advantage of the bottom with a light green paper bag.

"Wow, ha ha, really!" Jia Jia grabbed one, took a whimper and chewed, "this food is delicious, authentic American!"

At the same time, on the street of New York, in front of a hot dog car, the young black guy's eyes were straight. He didn't wake up from the scene just now. It seemed that a yellow man suddenly fell from the sky, took two hot dogs and left

In the black boy's hand, there was a crumpled RMB, black, yellow, black and yellow, with a steelworker on it, clutching a steel rod tightly!

In the evening, Hao Zhi and song Xiaojia sneaked out of the hospital. It's convenient to have Hao Zhi. They don't need to take a train or ship. It's a blink of an eye to go anywhere. The Ming Tombs and underground palaces, which they have visited before and many times in the future, are still a laboratory in the initial stage of construction.

Professor nado and a group of scientists gathered around the platform of the laboratory to analyze the secret of the crystal skull.

Hao Zhi and Jia Jia silently appeared behind them, startling everyone. Fortunately, the door of the laboratory behind them was wide open, and no one thought much.

"The underground cave investigation failed, and the clue to the crystal skull was broken. What a pity!" many professors seemed to be talking to themselves. "We used various methods to analyze it, but we couldn't find any clues. Hao Zhi, do you have any ideas?"

Hao Zhi smiled: "we have to say this..."

"Oh?" the professor looked at the scientists around him, showing an apologetic smile. Everyone was literate and naturally knew how to avoid suspicion, so they dispersed one after another. In the laboratory, there were only Hao Zhi, Jia Jia and Naduo professors.

"I think even if I don't say it, you will notice the missing paragraph in your memory sooner or later!" Hao Zhi looked at them and said.

"Well, I feel that my memory seems to be hollowed out for a period, blank and fuzzy, but I don't know what happened!" the professor leaned in front of the experimental platform with a calm look, "what happened? You seem to know?"

From the beginning, Hao Zhi said how to enter the cave, what he saw, what he found, the battle with giants, and how to talk with Adam when he met the prophet in the Blue Cave later

"Adam said that people without historical responsibility don't need to know these things, but I thought for two days. Professor Naduo is the leader of human science and technology, and Jiajia you are the God of doomsday war. You should have the right to share these information!" Hao Zhi's words have a lot of mature thinking, At the age of twenty-eight, he is no longer the rough child.

Professor nado pondered for a long time, as if digesting the details of his story.

Suddenly, he filtered out the last key words of the prophet: "the secret of acquiring knowledge lies in light!"

Hao Zhi is not a professional scientist, but he is a well-informed person here. Life experience is an invaluable wealth. He remembered what Lin Tao said. At that time, the Tianhe Super Brain Computer established by Professor Naduo obtained alien knowledge from light!

"Aliens hide advanced scientific knowledge in the light, and then launch it into the whole universe, so that the races who obtain knowledge can learn!" Hao Zhi approached the crystal skull, "maybe the secret of the crystal skull is also hidden in the light!"

Professor Naduo thought for a moment: "transmitting information with light... This technology is not a new invention. Since the British physicist Dindal discovered the principle of total reflection of light in 1870, the experiment of light as an information transmission medium has been improving. In 1966, Dr. Kao Kun, a Chinese scholar, published a paper" dielectric fiber surface waveguide of optical frequency "in piee magazine , the possibility of using optical fiber as transmission medium to realize optical communication has been analyzed and proved theoretically... "

"Optical fiber?" Song Xiaojia said, "that's not broadband. The Internet used in our era was optical fiber to transmit network signals!"

"Oh?" Professor Naduo felt very excited when he heard the news. "I can't imagine that this technology has been applied to the whole country in decades. You know, the year before last, that is, 1982, the" August 2 project "of the Ministry of Posts and telecommunications was opened in Wuhan..."

"Well, we had put forward a new concept of optical broadband at that time. As long as there is light, we can connect to the Internet wirelessly and obtain information in the network. It seems that it is very similar to alien technology!" Jia Jia said with big eyes.

It does mean that there is a ancestor... Hao Zhi thought about it. At present, it seems that the optical network has been popularized in the whole universe long before mankind entered the industrial revolution. Aliens have spread signals to every corner of the solar system in order to contact other civilizations

This further proves that my guess is correct

Professor Naduo and Jia Jia turned around at the same time. What did you guess?
