Shui Han stood in place, now Richu's clothes turned out to be black, when he just came out of the bushes, Shui Han has been following Richu, so he saw that it was obviously blue, if it wasn't for the instant change of clothes at the beginning of the day, then there was only one explanation, this open flame, this open flame that had been ignored by him, changed color, to be precise, it changed from blue or white to red, such an obvious change, it was actually ignored, 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, and under white light, all objects can reflect their own light, because white light is the collection of all light.

The reason why he now sees that the color of the clothes at the beginning of the day is black because the blue clothes do not reflect red light, that is, the light that is not the color of the object itself shines on the object and causes the object to turn black, and this effect is especially prominent in this condition of pure darkness without interference.

Shui Han looked at the red gate and the black rocks around him, and suddenly realized that this was the case.

Chongluan smiled on the side after not seeing him for a long time, and he was going to point out this guy, but he actually found out by himself, and it seems that his combat power has degenerated into five, but his IQ and insight are still there, and if you think about it carefully, this kind of thing is innate, where is it so easy to lose.

"Smack. "The door of the head was flicked, and the beginning of the day said:

"What do you think?"

Shui Han immediately came to his senses and said his thoughts to Richu.

There is a special case in the effect of light, that is, black objects, they cannot reflect any color of light, so no matter what light shines, it will only be black, and this mountain does not shine sunlight all year round, so the mountain is full of black rocks, in this pure black environment, it is such an abnormal door, and this open flame happens to be red at this time, just imagine, if the open flame at this time turns blue, what will we see?

At the beginning of the day, after listening to Shui Han's description, he seemed to understand something, and said:

"Are you saying that this red only appears under a red open flame, and if it is illuminated by other rays, it becomes black and hidden in the rocks?"

"That's right. ”

This can also explain why the carving on the door is so shallow, if the carving is too obvious, after all, there is light, it is not difficult to find. Shui Han took a closer look at the red giant gate again, if it turned black, it was really integrated with the surrounding mountains and rocks, so his guess was correct.

Shui Han continued:

"Since this open flame changes color, it means that there are other doors hidden in the valley, but they do not show their color in the red light, and they merge with the black rock, and we cannot detect it. ”

Ri Chu looked at Shui Han and listened carefully, and suddenly had a feeling that he felt that this guy was quite handsome when he was seriously thinking about and analyzing. She'd felt this before, but only once, and only for that person, the one who had disappeared again.

"Okay, let's go find them. ”

Shui Han was full of confidence, fortunately he didn't enter the door recklessly just now, that door must be a trick, if you rush in, you must have fallen into the trap. It seems that it is necessary to find out which doors are the ones to determine which one is the real entrance.

Shui Han just wanted to act.

"Smack. ”

The door of the head was bounced again.

"Stupid, you don't look at this valley so big, and those doors are so inconspicuous, you have to look for them one by one, when you want to find them, besides, if you guess wrong, it won't be in vain. ”

I couldn't stand it at the beginning of the day, and I just thought he was handsome, and he was beaten back to his original shape at once.

"What then?" Shui Han returned to his cute state.

"Wow. The beginning of the day pointed to the open flame, and said:

"I've just found a mechanism on the pillar that supports the flame, and it's supposed to change the color of the flame, and if that's what you say, then we can find out where the other doors are by simply changing color. ”

"Oh. ”

Shui Han responded, it seems that he was not idle at the beginning of the day, so he saved a lot of effort.

Shui Han immediately ran under the pillar and found that there were three button-like things on it, only three, could it be that there were only three colors of light?

Shui Han wondered, if it was a trick, three was too little, was it not enough to have enough funds?

I really can't stand those people in Rashomon, they are so stingy to be a trap, and they are destined to not become a big climate.

The leftmost of the three buttons has been pressed, and the flame is red.

Shui Han pressed the button in the middle again, the fire turned yellow, Shui Han turned around, and saw that the original red door was now only a mountain rock, and as expected, at the other end of the valley, another yellow door appeared, the style was the same as the red door, Shui Han was a little excited, and pressed the third button, the fire turned purple, and sure enough, another purple door appeared on the rock wall.

"That's all there are three gates. ”

At the beginning of the day, he watched the water cold operation on the sidelines and said.

"I guess it'......"

Shui Han is not sure, three, after all, it is too little.

"Stupid, didn't you notice that all three buttons are pressed now?"

Chongluan's voice sounded in his ears, Shui Han just wanted to scold back, and then thought about what he just said, if this is the case, if three buttons represent three colors, then why not one corresponds to one? When Shui Han pressed the button in the middle, the first button was not raised accordingly, that is to say, Shui Han was equivalent to pressing two buttons for the first time, and pressing three buttons at the same time for the second time, could it be ......

Shui Han went to pull out the first button that was pressed corresponding to the red light, and sure enough, it could be pulled out, and at the same time, the fire turned cyan, and the water cold pressed in, and the fire changed back to purple, so it was, if all three buttons were like this, then, there should be seven colors, if it was expected, it was probably red, orange, yellow, green, blue, cyan, purple seven colors.

The water cold experimented one by one, and it was really good.

"What's going on, how can there be seven colors?" Richu looked puzzled on the sidelines.

To better explain this, we have labeled the buttons with numbers 1, 2, and 3. Normally, we would think that they correspond to three colors, but the buttons are flexible, that is, the three numbers are randomly combined, so there will be 7 cases, which are

1, 2, 3, 12, 13, 23, 123, then they can correspond to the seven lights.

Richu seemed to understand, and said with a smile:

"I didn't think you'd be quite smart. ”

It seems that this guy has a strong ability to learn, no, it's not so much the ability to learn, but the curiosity driven, just like that guy.

Indeed, driven by curiosity, although Shui Han can't read books well and fights are often blown up, he knows a lot of these miscellaneous things.

"You don't look stupid. Chongluan looked at Shui Han silently, but there was a trace of interest in his heart.

"No, you're still far away!"

Chongluan and Richu spoke in unison, Shui Han was embarrassed for a while, and it was really not easy to deal with fantasy partners and reality partners at the same time.

"Now seven doors have been found, but which one is the right one?"

At the beginning of the day, the water cold was beaten back to reality, and I just patronized the door, but there are as many as seven of them, what should I do?

"Huh?" said that the beginning of the day seemed to see some clues.

"What's wrong?"

"Have you noticed that the valley is circular, and the gates are evenly distributed over the mountain walls, and the distances are even, but there is only a gap between the purple and red gates? ”

"You mean ......"

Shui Han's heart suddenly beat fast.

"And a door!"

The two shouted out almost at the same time.

Eight doors, there are eight doors in total, thinking about it, a word suddenly popped up:

Qimen Dunjia.
