Li Guanghan and Chen Aili gently slipped out of the secret room, intending to withdraw through the back door. But the rear door has been locked from the outside, and an infrared alarm has been installed. It is estimated that when Wei Jiajun came in through the back door, he found that the precautions at the back door were too weak, so he immediately took remedial measures. The two of them groped in the dark, Chen Aili quickly put on night vision devices, and infrared alarms were also installed on the door, and it seemed that the gate could not get out. Li Guanghan was shocked and anxious, and his autumn clothes and pants were all soaked with sweat. Chen Aili told him that it seemed that he could only pry open the flat window in the basement leading to the street, and let himself climb out first and then open the back door to save him.

Leaning on a little light from a street lamp on the street, the two men found an axe and an iron chisel in the dimly lit basement. Li Guanghan was about to move a chair over to pad his feet, but who knew that he couldn't move it, it turned out that a switch was connected to the chair legs! A door slowly opened behind the tool shelf, and it was pitch black inside, and the sound was deep. Chen Aili turned on the lighting rod, it was a straight tunnel, the ground was paved with smooth stones, and the walls and vaults on both sides were also neatly repaired, which could be seen to be old, not hastily excavated. The two of them were stunned, could it be that this was one of the famous secret passages built in the war-torn European Middle Ages? They carefully restored the basement furnishings to their original shape, and walked into the secret passage by the light of the light rods.

The secret passage is basically straight, except for a small turn, the general direction has not changed. Li Guanghan followed Chen Aili closely, both nervous and excited, he didn't know what would happen in a while, his life had changed dramatically in just a few days, his head was numb, and his thinking was stagnant. And Chen Aili has always been calm and calm, and she looks very angry when she is in danger, except for her expression when she sees the secret passage. It is certain that with her skills and equipment, she is by no means as simple as a small graduate student, and he even feels fortunate to have her by his side, and he is now very dependent on her. The two of them walked briskly for about half an hour, and finally smelled the fresh air!

A cool and sweet wind blew from the vent in the distance, and the two of them suddenly became more energetic and quickened their pace. There is a ready-made iron ladder under the vent, which is intact, and it seems that the secret passage is still in regular use. Li Guanghan struggled to push open the ventilation manhole cover, and when they completely climbed out of the ventilation shaft, they were greeted by the statue of the Hindu god on the lawn of the research center's garden, the metallic luster of the idol glowing a faint green light in the night. The two men looked at each other in amazement, it turned out that the tram on the ground had made a big bend, and this medieval secret road underground was the shortest distance in a straight line. Li Guanghan had thousands of question marks in his head at this time.

9 Deng Lao is missing

Chen Aili knew what Li Guanghan wanted to ask, but she motioned for him to rest first, she had other things to do, and she would be back soon.

It was late at night, and Li Guanghan's stomach was already rumbling with hunger, but his heart could not be calmed for a long time. He tried to calm himself down, intending to use rigorous scientific reasoning methods to sort out the events of the past few days.

What is certain is that for some reason she has been targeted since she was in China, and Chen Aili has always known about it, so she came prepared. At present, it seems that she can be trusted and relied on. And Wei Jiajun should be in the same group as "those people", he is too easy to trust people. The function of the apparatus and computer next to the black velvet recliner was supposed to be to hypnotize him after giving him the drug in order to read the memories and subconscious of his deep cerebral cortex. But are these memories and subconscious minds so important to "those people"?

Li Guanghan brewed a cup of green tea from his hometown, sat by the window, smelled the warm and familiar fragrance of tea, and looked at the green buds in the glass, his heart calmed down a lot, and his thoughts flew back to his hometown, when a light snow fell silently outside the window.

In 1973, Xiangxi, a remote mountain town. It was also such a cold snowy day. My father brought back from outside a tall, white uncle with a pair of thick-lensed glasses, a bloated cotton coat, and a white-washed satchel on his shoulder, which was full of books. 4-year-old Li Guanghan thought that there was a villain book, so he hurriedly went up to rummage through his uncle's satchel, and was scolded by his father and ran into his mother's room. My uncle lived in their house. Uncle Beijing loves to read, but those books are not understood by children. Adults also always say that Uncle Beijing reads books from heaven.

Half a year has passed, and Uncle Beijing has worked during the day, and after reading books at night, he tells Li Guanghan and them all kinds of interesting stories, which in today's words is scientific common sense. He can explain all kinds of phenomena and proverbs in ordinary life in scientific principles and simple language, which is pleasing and convincing. For example, why do you only hear their voices and not see their people? That's because the wavelength of sound waves is longer than that of light waves, so sound waves can go around high walls, while light waves cannot; Why is it said that one day in the cave has been in the world for a thousand years? That's according to Einstein's theory of relativity, in a spaceship close to the speed of light, time passes much slower than on Earth, and a few days in such a hole, hundreds of years have already passed on Earth; In the poem, "sitting on the ground and traveling 80,000 miles a day" also means that the earth rotates in a circle, and the objects on its surface are equivalent to walking 80,000 miles, revealing the relationship between motion and rest. Every time Uncle Beijing speaks, he will stand up and demonstrate to everyone, or do some small experiments on the spot, so that everyone can find the answer together. At a time when material and spiritual life was scarce, these interesting and warm scenes were deeply engraved in Lee's mind. It was the first time he had heard so many unfamiliar words, and these anecdotes and experiments sparked his intense curiosity. Inspired by Uncle Beijing, he was able to grasp faster and more thoroughly than other children, and the questions he asked were often to the point, and he could understand them with just a little touch. This also surprised Uncle Beijing.

On summer nights, everyone sits on the threshing floor to cool off. The adults would also tell a lot of strange legends that had been circulating in Xiangxi for a long time, and he always listened carefully, sometimes asked questions, and always smiled but did not answer in the end. Looking at the sky full of stars, Uncle Beijing said that in ancient Chinese mythology, there is a saying of "clairvoyance, ears to the wind", and now people can use electromagnetic waves to transmit sound and images, which has turned the myth into reality, and in the future we will also realize "Chang'e to the moon", "Sun Wukong somersault clouds", a heel fight is 108,000 miles. There are many secrets in the vast universe waiting for us to unravel, and many resources waiting for us to develop and utilize. The little guy is so talented, Li Guanghan will change his name to Li Guanghan in the future.

Many years later, after Li Guanghan was admitted to the Department of Physics of Huajing University, he went to visit Professor Deng, but he never expected that he would always remember this extraordinarily smart child in the mountains. He even half-jokingly said that it was because he laid a good foundation for Li Guanghan and changed his name well, so that this good seedling stood out in the mountains. Li Guanghan also lamented that if it were not for Professor Deng's enlightenment education and interest in physical science, he might still be farming in the mountains.
