Chapter 482: Light and Shadow

An hour has passed, and Uncle Lu, Yun Ximing, and I are almost about to turn this tomb upside down, but let alone the mechanism, we haven't even found a single extra brick.

"It is said that even if there is any mechanism, there must be some traces, but it is really strange, how can there not even be a suspicious place in this tomb, could it be said that the mechanism in this tomb is actually a dead pass, and there is no desire to let the people trapped here go out at all?" Yun Ximing said.

"What? Brother Childe, what do you mean? Are you saying we can't get out? By... Stuck here? Dazhe asked.

"I don't think so." Uncle Lu said.

"Uncle Lu, when you say that, do you think of something?" I asked.

"Think about it, what kind of place is this, and who else will come here besides Zuo Ci? Or who does Zuo Ci want to come? Uncle Lu asked.

"You mean to say... Protoss? Yun Ximing asked.

"That's right, according to Zuo Ci's epitaph and what Lao Zuo told us, what is hidden here is an ancient artifact, so from this point of view, the descendants of Zuo Guo inherited the will of their ancestors, guarding the artifact here, and at the same time waiting for the arrival of the gods. Since they knew that the Protoss would come, they would definitely not design any mechanism that would endanger the lives of the Protoss. Uncle Lu said.

"What Lao Lu said is not wrong, but if the person who comes is a descendant of the Protoss, then what kind of mechanism will Zuo Ci design, so that the descendants of the Protoss can find the mechanism, but others can't find the location of the organ?" Yun Xian said.

"Then you have to ask Yin Yin, Yin Yin. If you were Zuo Ci, what kind of clues would you leave for yourself, which only you know and others can't find? Uncle Lu asked me.

"If it's me, it's just... Ghost text. I walked to the place where the stairs were originally located, and I carefully examined them, but I was a little disappointed that I didn't see the ghost text, but only a notch on the ground, which was a pattern carved into the stone bricks on the ground. It is also a three-legged golden crow. In this burial chamber. The bronze carvings on the furnishings and the murals on the walls all have a three-legged golden crow pattern, and it is not surprising that there is such a pattern on the ground. What's more, Yun Ximing and Uncle Lu had already inspected it in detail just now. There is nothing wrong here.

"How about Yin Yin? Are there any clues on the ground? Yun Ximing asked.

I shook my head. "No, and I realized it when I was checking it just now. There won't be any ghost texts on this earth, because the ghost texts are all clues left by the ancestors of our Kui clan to the descendants of our clan, even if we know that we are the gods who can understand ghost texts and know yin and yang, Zuo Ci will not leave me such clues, because he himself doesn't know how to use ghost texts at all, and he doesn't have yin and yang techniques, so our speculation just now is incorrect. I said.

"That's really strange, could it be that this Zuo Ci, in addition to resenting his own clansmen, even the Protoss is also disgusted, so he doesn't want the Protoss to be able to find the artifact at all?" Yun Xian said.

"It shouldn't be, Zuo Ci is a person who knows right from wrong, and is upright, the reason why he hates his own people is because the descendants of Zuo Guo are really ignorant, but the gods and artifacts are all very important to the whole world, and Zuo Ci will never be so extreme." I say.

"It's weird..."Yun Ning's voice sounded behind me, and I turned around and saw Yun Ning looking at the ground and saying strange.

"Yun Ning, what's wrong, what did you see? Talking weird all the time. I said.

"Sister Yin Yin, look at the ground, there doesn't seem to be much light in this room, but we don't even have any shadows." Yun Ning said.

I looked down and saw that there was no shadow of anyone on the ground.

"It's these lampholders in this burial chamber, because the distribution is very scientific, so we don't leave a shadow on the ground." I say.

"Is this the principle of the shadowless lamp used during surgery?" Sister Wang Na asked.

"yes, that's what it means." I say.

"No, what's that... What is a shadowless lamp? Dazhe asked.

"Surgical shadowless lamps, which are used to illuminate the surgical site for optimal visualization of small, low-contrast objects at different depths in incisions and body cavities. Since the head, hands, and instruments of the surgeon may cause disturbing shadows to the surgical site, the surgical shadowless lamp should be designed to minimize shadows and minimize color distortion. In addition, shadowless lamps must be able to work continuously for long periods of time without emitting excessive heat, which can cause discomfort to the surgeon and dry out tissues in the surgical area. Sister Wang Na said.

"Of course I know this, I mean, why is there no shadow in the scene illuminated by this shadowless lamp, I didn't think about this problem before, but now that you are so many capable people here, who can explain it to me?" Dazhe asked.

"I learned about this when I was studying medical knowledge. A shadowless lamp is not actually shadowless, it just fades the umbra so that it is not obvious. Shadows are formed when light hits an object. The shadows are different everywhere on Earth. If you look at the shadows under the electric light, you will also notice that the shadows are particularly dark in the middle and slightly lighter around them. The particularly dark part of the shadow in the middle is called the umbra, and the gray part around it is called the penumbra. The occurrence of these phenomena is closely related to the linear propagation of light. If you place a cylindrical tea tube on the table and light a candle next to it, the tea tube will cast a clear shadow. If two candles are lit next to the tea tube, two shadows will be formed that overlap but do not coincide. The part where the two shadows overlap is completely black, and this is the umbra, and the place where there is only one candle next to the umbra is the half-light and half-dark penumbra. If you light three or even four candles, the umbra will gradually shrink and the penumbra will appear in many layers. The same is true for objects that can produce shadows composed of umbra and penumbra under electric light. Obviously, the larger the area of the luminous object, the smaller the umbra. If we light a circle of candles around the tea tube, the umbra disappears completely, and the penumbra fades into obscurity. According to the above principle, scientists have made a shadowless lamp for surgery. It arranges the lamps with great luminous intensity into a circle on the lamp panel to form a large area of light source. In this way, the light can be irradiated to the operating table from different angles, which not only ensures that the surgical field of vision has enough brightness, but also does not produce obvious umbra, so it is called a shadowless lamp. We used to do this experiment in class, and it was really interesting, and these lamp holders in this room are in a circle, so just like the principle of shadowless lights, naturally there is no shadow. Sister Wang Na said.

"I see." Dazhe said.

"But from this point of view, the design of these lampholders does not seem to be arranged randomly, if it has not been accurately measured in advance, it should not achieve such an effect, could it be said that Zuo Ci has any intention in doing this." Min Lan said.

"I'm afraid it's obvious, because these lampholders may be the way to unlock the mechanism." I say.

"No wonder we checked the lampholders just now, but found nothing, and now it seems that it has nothing to do with the lampholders themselves, but with the location of these lampholders. But what's the use of knowing this? Yun Ximing said.

"That's what I'm saying, there are twenty or thirty of these lampholders at random, so could it be that you blow them all out, right?" Dazhe said.

"Fatty, what you said was light, all blown out, it was pitch black, how can we walk." Yun Ximing complained.

"No, this time, you guys are really wrong, what Dazhe said this time seems to have some truth. If you think about it, why did Zuo Ci design this house like this, why would there be no shadow after everyone came here? I asked.

"Because... Yin Yin, you mean, has something to do with the shadow? Yun Ximing said.

"At present, this is just my speculation, Zuo Ci's design, obviously because if there is a shadow on the ground, it may trigger a mechanism, so in order to avoid such a situation, let all the people have no shadow. In other words, as long as we destroy the current environment and extinguish a few lampholders, a shadow will appear on the ground, and we will be able to set off to the next level. I said.

"So, it does, but which ones do you want to extinguish?" Yun Xian asked.

"According to Sister Wang Na, when there is only one lampholder, the umbra is presented, and the shadow is the clearest, I guess Zuo Ci may have intended for us to leave only one lampholder and get the shadow he wants." I say.

"Okay, we have another direction, so the question is, which one of the many lampholders are we going to stay?" Dazhe said.

"Fatty, let you come, it's for you to think of a way, but it's not for you to come here to sort out your thoughts and ask questions, which will add to the blockage." Min Lan said dissatisfied.

"I think—" I hesitated, then looked around, "don't you think it's possible that I'm wrong." I said.

"What error?" Yun Ximing asked.

"If you are worried that someone will come in and inadvertently trigger the mechanism, then it can only be said that the design of the mechanism is still unreasonable and not rigorous, which is not like the practice of the ancients. Maybe there's something that doesn't move at all, and as long as it has a shadow, it will definitely trigger the mechanism, so that's reasonable enough. I said.

"There are only things that don't move here..."Uncle Lu said and looked at the platform with the bronze sculptures.

I turned my head to look at the lampholder facing the platform, and drew in my mind the situation where the lampholder was lit alone, and then looked at Uncle Lu, "Uncle Lu, you are the most sure of the direction, you see, what is the direction of this lampholder?" I asked. (To be continued.) )
