But at this time, Zhang Desen discovered that the light in the string window was fluctuating to a certain extent. The hacker guessed that an alien might be coming to the porthole to see the outside scene.
Sure enough, it wasn't long before the alien was able to go to the window and look outside. Zhang Desen had no choice but to climb down the climbing area and enter the blind spot of the porthole to avoid the detection of the alien who was peering out.
However, the alien didn't stay too long. When he saw everything was normal outside, he went back. Then, after Zhang Desen confirmed that everything was safe, he climbed to the string window again and looked inside.
However, this time he looked up at the shadowless lamp hanging from the ceiling. This was a bit surprising to him, because those shadowless lamps were different from those Zhang Desen had seen in the past. Their light was emitted from some small holes. The light emitted is very soft, but the brightness is also very high.
Moreover, most of its shadowless lamp styles are mainly flat-panel.
By the way, surgical shadowless lights are used to illuminate the surgical site for optimal viewing of small, low-contrast objects at varying depths in incisions and body cavities.
Since the operator's head, hands and instruments may cause interfering shadows on the surgical site, surgical shadowless lights should be designed to eliminate shadows as much as possible and minimize color distortion.
In addition, the shadowless lamp must be able to operate continuously for a long time without emitting excessive heat, which can cause discomfort to the operator and dry out the tissues in the surgical area.
In fact, the shadowless lamp does not "shadowless", it just lightens the umbra and makes it less obvious. Shadows are formed when light hits an object. Shadows are different everywhere on Earth.
If you carefully observe the shadow under electric light, you will also find that the middle of the shadow is particularly dark and the surrounding area is slightly lighter. The particularly dark part in the middle of the shadow is called the umbra, and the surrounding gray part is called the penumbra. The occurrence of these phenomena is closely related to the linear propagation of light. If a cylindrical tea cylinder is placed on the table and a candle is lit next to it, the tea cylinder will cast a clear shadow.
If two candles are lit next to a tea cylinder, they will form two shadows that overlap but do not overlap. The overlapping part of the two shadows has no light at all and is completely black. This is the umbra. The place next to the umbra that can only be illuminated by a candle is the penumbra, which is half-light and half-dark.
If you light three or even four candles, the umbra part will gradually shrink, and the penumbra part will have many layers. This is also the case when an object under electric light can produce a shadow composed of an umbra and a penumbra. Obviously, the larger the area of the luminous object, the smaller the umbra.
If we light a circle of candles around the tea cylinder, the umbra will completely disappear and the penumbra will be too faint to be seen. Scientists have made a shadowless lamp for surgery based on the above principles. It arranges lamps with high luminous intensity in a circle on the lamp panel to form a large-area light source.
In this way, light can be irradiated onto the operating table from different angles, ensuring sufficient brightness for the surgical field without producing an obvious umbra, so it is called a shadowless lamp.
Looking at these shadowless lights in front of him, Zhang Desen had to say that the technology of alien civilizations is indeed much more advanced. Because if you don't look carefully at these shadowless lamps, or if they are on, you won't be able to tell that they are the same lamp. They are almost completely integrated into the ceiling, and when the lights are not on, they even feel like they are just part of the wall.
However, Zhang Desen suddenly thought of something. The high technology of aliens is not necessarily something completely different from ours. Some things may be the same scientific and technological achievements that we all have as humans. Just outside
The Xingren application is more mature, has higher technological content, and has more comprehensive functions.
However, Zhang Desen may not be able to rescue these humans inside now. We had to complete the mission first and figure out the aliens' intentions. Then, Zhang Desen continued to walk towards the upper part of this huge cigar-shaped space carrier.
But at this time, Li Longfang called Zhang Desen again and said:
"Captain, captain, what happened just now? Have you been discovered?"
Zhang Desen replied:
"Don't be so surprised, okay? I've already hid in the blind corner, they couldn't see it at all, and now I'm going to keep going up. If you continue to be surprised like this, I won't Be careful it's possible
I will fly into space. In that case, do you know how to fly a spaceship to rescue me? "
Li Longfang was startled and immediately replied:
"Sorry captain, I thought they had discovered it for a moment. So I asked."
Zhang Desen replied helplessly:
"Okay, Brother Long Fang, just don't be so surprised. Just guard the spaceship. I'm going to go to their upper main control room."
After hearing this, Li Longfang said:
"clear!!!"
Then, Zhang Desen continued to walk up, but although he saw a few windows along the way, they were not of much interest.
…
However, at this time, outside the Liu Family Trading Company Airport outside Hezhou City, the northern important town where mankind is flourishing on earth. The father and his daughter, General Feng Yucai of the Daxing Kingdom, who were guarding outside this storage point, felt that they were being ignored by others, which made them very dissatisfied. At this time, Feng Linger said to his father Feng Yucai:
"What's going on with this Zhang Desen? Our father and daughter came to help him with good intentions, but he turned out to be so ungrateful. I'm afraid time has passed by this time, right? I didn't see what he was going to do?"
Feng Yucai also felt a little unhappy and said:
"Yes, Zhang Desen is actually a very nice person. Isn't this a bit too arrogant now? It seems that there are any problems that my army can't solve? Now he only wants to rely on the joint generals of Zhang and Liu's mansions To solve the problem, isn’t that too conceited?”
Then, Feng Linger immediately stood up and said:
"I can't wait any longer. I'm going to go to him now and ask him what he thinks of us? Don't think that he's a big deal just because he broke the sword in my hand. That's because I'm not prepared. I have to do it next time we meet. I want him to have a taste of my swordsmanship."
But Feng Yucai suddenly thought about it and said:
"No, wait. Maybe Zhang Desen has a deeper meaning. After all, the things he did before have shown his wit. He may not be the kind of person who is too conceited. I think we should wait and see, how about? "
But Feng Ling'er couldn't wait any longer, and she said unhappily:
"Humph, I have never been looked down upon by anyone. And this Zhang Desen himself has actually left me out in the cold. I must tear him into pieces."
After hearing this, Feng Yucai was a little surprised and said:
"Hey, don't you have a crush on him? If you are always like this and can't change your temper, how can you get married? Besides, even if Zhang Desen is really a little arrogant, after all, he is still young, he is still It can be changed.”
However, Feng Linger was a little reluctant and said:
"Huh, at worst, I just need to accompany daddy.
Lifetime. Not getting married anymore. "
However, Feng Yucai couldn't help but smile a little and said:
"Yes, yes, you always said in the past that the husband you were going to marry in the future must be a man of great talent, superb swordsmanship, and an all-rounder who can kill enemies on the battlefield. But after you heard the appearance of the 'Weird Doctor', Even others say that the "hero in strange clothes" may be just a guy, he may not necessarily be a talented person, he may even always cover his face, and he may not necessarily be very good-looking, but you say you won't marry anyone other than him. And you still stand for He made a lot of excuses, but now you say this, can you do it now?"
After hearing this, Feng Ling'er couldn't help but blush and said:
"Oh, daddy, I'm not convinced now. Besides, that Shang...Miss Liu Yuting can fall in his eyes, why can't I fall in his eyes? No, I must go in and see what he is doing. ?”
Then, Feng Ling'er suddenly thought of something again. said:
"Dad, get me another sword. I will never let Zhang Desen underestimate me, and the sword was cut off so easily last time, so I must get a better one next time."
However, Feng Yucai said:
"I'm afraid this can't be done, because your 'Qingyu' is a unique sword. It ranks absolutely high in the rankings of all swords. But now Zhang Desen cuts it off when he says it. I'm afraid no one can deal with Zhang Desen's portable weapon. You are putting your father in a difficult situation. "
Then, Feng Yucai changed his tone and continued:
"Besides, you don't know where most of the weapons in your world come from. So where do you want dad to get you another sword like this?"
Feng Linger thought for a while and said:
"Forget it, we'll have to deal with Zhang Desen in the future about the sword. Now let's go in together and ask him what he is doing? Now we are all here to help him with good intentions, why are we so ignored? Let's go!"
Feng Yucai thought for a while and then said:
"It just so happens that we are not far from the gate of the Liu's store outside the city. It's only twenty or thirty steps away. Let's go over and ask now."
Afterwards, General Feng Yucai and his daughter immediately stood up and walked towards the gate of the Liu Family Trading Company's stocking point.
…
And at the same time. In the office of the head of state in Basin City, the capital of the Terrifying Galaxy Empire, the chief of staff of the Galaxy Empire, Mor Ross, said to his head of state, Goba Shaw:
"My head of state, in my opinion, it is better for us to directly deploy our thunder array."
After hearing this, the head of the Galaxy Empire, Goba Xiaofu, immediately asked:
"Why? I think we can complete our mission ourselves. After all, our country does not have such a strong Tianlei logistics reserve. Once too many are deployed, our logistics will be under double pressure. It is better to leave it entirely to Yuri. The Gortner Group will take care of it."
However, Moore Ross immediately said:
"But, my head of state. If it is completely handed over to Yuri Gortney, they may be full of loopholes. We have received corresponding intelligence. The space pilots Carl Wade and Dar Jin of their Yuri Gortny group De was captured by the Gomars, and a lot of information was leaked.”
Upon hearing this, Goba Shaw immediately asked More Ross to explain the detailed process, and More Ross immediately gave a complete report to Goba Shaw.
