Shui Han stood there blankly. Now Richu's clothes turned out to be black. When he just came out of the bushes, Shui Han had been following Richu, so he could see that they were clearly blue. If Richu hadn't changed instantly If he was pretending, there was only one explanation. This open fire, which he had always ignored, changed color. To be precise, it changed from blue or white to red. Such an obvious change actually gave Ignoring it, Shui Han really wanted to slap himself.
The reason is very simple, it can be said to be common sense. The object itself does not emit light. The reason why we can see objects with the naked eye is because they reflect the color of light. Objects of different colors can only reflect the light corresponding to their own color. Under white light, all objects can reflect their own light, because white light is the aggregate of all light.
The reason why he now sees that the color of Richu's clothes is black is because blue clothes cannot reflect red light. That is to say, light that is not the color of the object itself will make the object turn black when it shines on it. This effect is here This is especially true under conditions of pure darkness and no interference.
Shui Han looked at the red door and the surrounding black rocks again, and suddenly realized that this was the case.
Zhong Luan showed a smile that he hadn't seen for a long time. He originally planned to give this guy some advice, but he discovered it himself. It seemed that his combat power had degraded to five, but his IQ and insight were still there. If you think about it carefully, this kind of thing is innate. Well, it's so easy to lose.
"Pah." After being hit on the forehead, Richu said:
"What are you thinking about?"
Shui Han immediately woke up and expressed his thoughts to Richu.
There is another special case in the effect of light, that is, black objects cannot reflect any color of light, so no matter what light shines on them, they will only be black. And this mountain does not get sunlight all year round, so the mountains are covered with It's Black Rock. In such a pure black environment, such an abnormal door was built. Moreover, the open flame happened to be red at this time. Just imagine, if the open flame at this time turned blue, what we would see would be what is it then?
After listening to Shui Han's description, Richu seemed to understand something and said:
"You mean, this red color can only appear under a red open flame. If it is illuminated by other lights, it will turn black and be hidden in the rocks?"
"That's right."
This can also explain why the carvings on the door are so shallow. If the carvings were too obvious, it would not be difficult to spot them after all, given the light. Shui Han took a closer look at the huge red door. If it turned black, it would indeed be integrated with the surrounding rocks. In this way, his guess was correct.
Shui Han continued:
"Since the open flame changes color, it means that there are other doors hidden in the valley, but their color cannot be displayed under red light, and they are integrated with the black rock, so we cannot detect it."
Richu looked at Shui Han and listened carefully. Suddenly, he felt that this guy was quite handsome when he was thinking and analyzing seriously. She had felt this way before, but only once, and only for that person, the person who had disappeared.
"Okay, let's go find them."
Shui Han was full of confidence. Fortunately, he didn't enter the door rashly just now. The door must be a trap. If he entered rashly, he would definitely be trapped. It seems that we need to find those doors and compare them to determine which one is the real entrance.
Shui Han was just about to take action.
"Snapped."
The forehead was flicked again.
"Idiot, don't you realize how big this valley is and how obscure the doors are. You have to look for them one by one and when will you find them. Besides, if you guess wrong, it will be in vain."
I couldn't stand it at the beginning of the day. I thought he was handsome just now, but he was suddenly brought back to his original state.
"What should we do?" Shui Han returned to his cute state.
"Here." Richu pointed at the bright fire and said:
"I just found a mechanism on the pillar supporting the open flame. It should change the color of the open flame. If it is true as you said, then we only need to change its color to find out the locations of the other doors one by one."
"oh."
Shui Han responded. It seemed that Richu was not idle either. This way, he saved a lot of effort.
Shui Han immediately ran under the pillar and found that there were three button-like things on it. There were only three. Could it be that there were only three colors of light?
Shui Han wondered, if it was a cover-up, three would be too few. Could it be that there were insufficient funds?
I really can't stand those people in Rashomon, they are so stingy even in setting up a trap, they are destined not to become a big deal.
The leftmost button among the three buttons has been pressed, and the open flame shows red.
Shui Han pressed the button in the middle again, and the fire turned yellow. Shui Han turned around and saw that the place where the red door was originally was now only mountains and rocks, and as he expected, on the other side of the valley, At one end, another yellow door appeared. The style was exactly the same as the red door. Shui Han was a little excited and pressed the third button. The fire light turned purple. As expected, another purple door appeared on the rock wall.
"So it's just these three doors."
Richu said, watching Shuihan operate from the side.
"probably……"
Shui Han was not sure. Three was too few after all.
"Idiot, didn't you notice that all three buttons have been pressed now?"
Chong Luan's voice rang in his ears. Shui Han was about to curse back, but then thought about what he just said. If that's the case, if three buttons represent three colors, then why don't they correspond to each other? When Shui Han pressed the middle button, the first button did not lift accordingly. In other words, Shui Han pressed two buttons for the first time, and pressed three buttons at the same time for the second time. Button, could it be...
Shui Han pulled out the first button corresponding to the red light that was pressed. Sure enough, it could be pulled out. At the same time, the fire light turned into cyan. When Shui Han pressed it in, the fire light turned back to purple. So, if that's the case, if If the three buttons are like this, then there should be seven colors. If the prediction is good, they are probably red, orange, yellow, green, blue, cyan, and purple.
Shui Han experimented one by one, and it turned out to be good as expected.
"What's going on? How come there are seven colors?" Richu looked puzzled.
To better explain this problem, we label the buttons with numbers 1, 2, and 3 respectively. Under normal circumstances, we would think that they correspond to three colors respectively, but the buttons are flexible, which means that these three numbers are randomly combined, then there will be 7 situations, namely
1, 2, 3, 12, 13, 23, 123, then they can correspond to seven kinds of light.
Richu seemed to understand and said with a smile:
"I didn't expect you to be quite smart."
It seems that this guy has a strong learning ability. No, it's not so much learning ability, but more driven by curiosity, just like that guy.
Indeed, driven by curiosity, Shui Han knew a lot about these miscellaneous things even though he was not good at reading and often got beaten up in fights.
"You don't look stupid." Zhong Luan looked at Shui Han silently, with a hint of interest in his heart.
"No, you're still far away!"
Chongluan and Richu said in unison, Shuihan felt awkward. It was not easy to deal with imaginary partners and real partners at the same time.
"Now seven doors have been found, but which door is the correct one?"
Richu's words brought Shuihan back to reality. He had just been looking for a door, but there were seven of them. What should he do?
"Huh?" Richu seemed to see some clues.
"What's wrong?"
"Have you noticed that this valley is circular, and the doors are evenly distributed on the mountain wall, and the distances are even, but there is only a gap between the purple door and the red door."
"You mean..."
Shui Han's heart suddenly beat rapidly.
"There's another door!"
The two of them shouted almost at the same time.
Eight doors, eight doors in total. As I was thinking about it, a word suddenly came out:
Qi Men Dun Jia.
