"It's coming, it's coming! The water is coming again! It's really like a tide! Let me see, it's thirty-seven minutes apart."
Mu Yi held her watch this time and enjoyed the scene of the second wave of "water overflowing the golden mountain". Fortunately, the top wave barely wet their calves, and then it quickly receded, and - ——This also happened to be the time when the rope ladder disappeared——all extraneous attachments were removed.
"This is the interval between these two times. We need to measure it at least twice more. With three sets of data, we can judge how to proceed or whether to proceed."
Wenzi gave new suggestions, which are still in line with the principles of statistics: the minimum sampling size, the sample size must be sufficient, at least more than thirty, so that the measured results can minimize the sampling error and have a high degree of confidence. Of course, assuming that each interval is 37 minutes, if we really want to complete thirty sets of data, and each interval is about the same length, it means we have to stay here for 1110 minutes, which is 18 and a half hours, which is obviously unrealistic. ; So we will shorten it to three times and make a rough judgment.
"Look, these hollow dark cloud domes, those empty parts, I really want to fill them with something! Haha, do I have obsessive-compulsive disorder? I can't see that there are holes here."
Muyi obeyed and continued to look at the watch, continuing to wait for the second sample "tide" to rise. She was bored with waiting, so she stood up and discussed with Wenzi the dark clouds filling the "sky".
"Well, you have the ability. Draw something, shoot it in, and see if it can pass through those holes." Wenzi also smiled in a nonchalant way, knowing clearly that the dark clouds are loose gas, but encouraged Mu Yi to actually penetrate. Virtual.
"Of course, let's shoot the whole laser pointer in first and see. Maybe it can hit a star inside the cloud cover!"
Muyi did as she was told, and soon, her magic weapon, the wooden hairpin, drew a very small laser pointer in the air, and then handed it to Wenzi's hand. She said with a smile: "You come to test fire, I have to watch." Here’s the watch!”
"Okay! How far can this pen shoot?" Wenzi took the laser pen and played with it with great appreciation.
"Don't point the pen at people!" Muyi saw that he was clumsy and almost pointed the light into his own eyes, so she quickly helped him correct the way he held it, "Look, the pen is pointed at the cloud, and the button is at the thumb position, yes. Just click here.”
When she was very young, Fumiko's favorite thing to do in winter was to stand in the yard on a snowy night, holding the lantern in her hand and raising it to the sky. The light could still illuminate a large area at the beginning. The snowflakes falling and flying towards the ground can follow this inverted cone-shaped light column upward. The snowflake particles in the light column become smaller and smaller, and darker and darker. Not far away, they can no longer be illuminated.
He was very curious, where did that light go?
In order to study the light, he also covered the mouth of the lampshade with the light on with his palms and fingers. Only the red little hands could be seen, and the general shape of the bones could be seen inside. The color was so red and black, especially the The little finger, a pointed end bone, has a rounded end, which is all interesting.
And now, the laser pointer given by Mu Yi in his hand is much more powerful than that lantern, and its range can definitely hit the hole in the hollow cover of the dark cloud above his head.
Fumiko grabbed the tree trunk with one hand and raised the laser pointer to the sky with the other hand, just like he was a child on snowy winter nights in his childhood, shooting in an unknown direction.
As far as the eye can see, a green laser shot from Wenzi's hand accurately swept into a hole in the hollow dome of the dark cloud closest to them in the sky. In the part where it entered, the green light was still moving forward, straight. It shot into the inner lining of the cloud and was reflected back by the clouds inside, colliding back and forth. Within the dark cloud cover, a network of green light beams suddenly appeared. The brightness gradually attenuated from the end of the injection, and the color of the light decreased. , these linear green light nets present a unique visual effect, and the slight vibration caused by Fumiko's breathing can make this light net change shapes in a wide range, like a hard-brush sketch, with hard brush strokes Underneath, it showed a dynamic feeling like a swimming dragon.
Moreover, Fumiko pressed his thumb lightly, and the dragon disappeared suddenly, as if it had suddenly disappeared among the stars. When he pressed it again, the green dragon reappeared, which was very wonderful!
"Wow! It's so beautiful!"
Muyi was also fascinated by this artificial beauty. She never thought that the thing she made would bring about a "light show" - of course, it would still be to the rhythm of Wenzi's "Dragon Dance" Good control.
"It looks good, but since we can't go up, we have to find a way from below!"
Fumiko played for a while and then returned to the business of solving real problems.
The two squatted together, one looked at the watch, and the other tried to shine the laser pointer down to see how far it could shoot. Wenzi saw that the densely covered black stick leaves where he shot his menstruation were burned by the laser pen. The green light entered the bottom. In the center of the black circle, there was not a small green dot as imagined, but the green light column gradually decreased. , also gradually disappeared into the bottomless black spot.
"Look, the part that's shooting down has no bottom! We thought it was a tree, but it doesn't look like it! It's more like a bottomless shrinking black hole! I think the direction we're going down is , it’s definitely not right. Otherwise, let’s find a way from the water coming over! Could this water take us out of this black stick jungle?”
Wenzi analyzed it and found that the dark clouds and stars above were so empty and loose, and the trees below were rootless and bottomless. If the vertical direction didn't work, then he had to find a way out horizontally.
"Wait a minute, I still haven't figured out where this water comes from!"
Muyi glanced at the hands on the watch again, and continued to look around under the tree: there was almost no movement here. It was so quiet that there should be no other creatures that could survive here.
"It stands to reason that if there is a jungle, there should be small animals. These sap-filled leaves should also provide some nutrients for some creatures to eat! Otherwise, there is no need to be so strong on the outside, but they are so fragile on the inside!"
Muyi used the earth theory to apply it here, but she always felt that something was wrong.
"Or, the tree we are standing on is not a 'jungle' at all, but something else? Therefore, the 'law of the jungle' cannot be applied."
Wenzi put forward a new idea. After all, photosynthesis is also the specialty of chlorophyll, not the function of black rubber skin.
"If it's not a plant, would it be an animal? A microorganism? Is there something else in the belly of the algae?" Muyi began to imagine the cross-section of the algae creature.
