Ding Xuecheng walked to the console, calmed down, raised his right hand, pressed to the "shock position", and the question that emerged under the palm of his hand was: "What is hidden in the picture?" Immediately after the 4 pictures appeared, the friends opened their eyes wide and searched carefully.

Kiki glanced at it and said with a smile: "Bobo~ Your luck is so good!" Isn't that simple? Leaves, flowers, dead grass, fallen leaves. ”

Yanyan pulled Kiki's arm and whispered, "Look closely, there are insects in the dead grass...... It seems like there are bugs in every picture......"

"Yeon-yeon is right, these are magical camouflage methods for small animals in nature to protect themselves or to hunt." Binbin added.

Kiki exclaimed, "Huh? Really yes~! I see it...... However, in the other three pictures, I didn't see the bugs~...... Also, what are their names? ”

Bin Bin held his round chin, pondered for a moment, and said: "I only know the insect in the dead grass, which is a kind of stick insect, and I don't know any other insects. ”

Yeon-yeon stared at the picture for a while, shook her head, and said to Kiki, "I don't know either." ”

When the three friends were discussing, Ding Xuecheng was communicating with Beibei: "Beibei, fortunately, I learned this part of the content in advance and checked the information, otherwise it would be over, it's so dangerous!" ”

"In this kind of activity, I strictly prohibit prompting, otherwise, you will directly fail, and I will finish playing...... Obliterate! ”

"I understand~ If you can't participate, don't respond, I'll understand what's going on!"

Ding Xuecheng gave his friends a reassuring look and said loudly: "The answer to the seismic question: In the first picture, the insect that looks like a leaf is called a leaf insect; In the second picture, the petal-like bug is called the orchid mantis; In the third picture, the worm that looks like a dead grass is called the stingy-footed stick beetle; In the fourth picture, the insect that looks like a dead leaf is called a dead leaf mantis, and it may also be a dead leaf butterfly. That's it! ”

The friends listened nervously to Ding Xuecheng's answer, recalled the appearance of the insect in the picture in their minds, and stared at the stone gate with their eyes. It wasn't until the earthquake position was lit up that the three of them let out a breath that they had been holding for a long time, jumped and cheered, and shouted one after another: "One step closer to success, there is still one last hexagram...... Bobo, come on! ”

Ding Xuecheng withdrew his right hand and pressed his left hand to the last hexagram - "out of position", and the question that emerged was: "Where does the white fog on the popsicle come from?" ”

Kiki spread her hands and said, "Of course it came out of the popsicle." ”

"Is it true?" Yeon-yeon didn't believe it would be that simple.

Bin Bin pointed to the side of the test bench and exclaimed, "What's that?" Just rising! ”

The three of them ran over to inspect it together.

Kiki was the first to make a discovery, saying, "Isn't this just a stone cabinet?" Look, here's the doorknob, open it and see? ”

"Is there any danger?" Yeon-yeon reminded.

"I'm coming!" Binbin forcefully opened the door of the "stone cabinet".

Kiki: "Wow~ It's a refrigerator~!" There are also popsicles inside, crisper bags. ”

Yeon-yeon: "You're going to do the last experiment for us, right?" Popsicles need to be kept in the refrigerator, so the refrigerator came into being. ”

Kiki: "Makes sense! But doesn't it mean that there is no electricity here? How to use the refrigerator? ”

Binbin: "It can save popsicles, don't worry about it!" Let's hurry up and do the experiment. ”

Kiki: "Oh~ too! We took out the popsicles and the crisper bags. ”

The three of them came to the experimental table and tore open the packaging bag on the popsicle, only to see that the "white mist" on the popsicle was misty.

Kiki said proudly: "I'll just say it~ 'White Mist' came out of the popsicle!" ”

"What is this bag for?" Yeon-yeon asked, tilting her head.

Ding Xuecheng pressed his hand on the stone platform, kept paying attention to the movement here, and hurriedly reminded: "Wrap the popsicle in a fresh-keeping bag, if there is no 'white mist' appearing, it means that Qiqi's statement is right; ”

Bin Bin thought for a while, and according to Ding Xuecheng's instructions, the two little girls stared with wide eyes.

Waiting for Binbin to wrap the popsicle tightly with a fresh-keeping bag, after a while, the "white fog" outside the fresh-keeping bag was still there.

Kiki said in annoyance: "Wrong~ This 'white mist' didn't come out of the popsicle, where did it come from?" ”

Yeon-yeon muttered to herself, "In the air? ”

Kiki: "I can't see it when I don't have a popsicle~"

Binbin: "This shows that the formation of 'white fog' is related to the low temperature of popsicles. ”

The three of them were still discussing, and Ding Xuecheng's voice came from there: "The answer to the question of detachment: There is water vapor in the air, and when the water vapor encounters the low temperature of the popsicle, it will liquefy and condense into very small water droplets, and a large number of small water droplets gather together to form a 'white mist'." That's it! ”

As Ding Xuecheng's voice fell, the last hexagram on the stone gate was lit. The light of the entire stone gate flickered, the runes flowed, the brilliance gradually faded, and finally, the center of the gossip pattern lit up, and it was a pair of rotating yin and yang fish. The black eyes of the "yang fish" flicker, while the white eyes of the "yin fish" do not react.

The crowd waited for a while, but there was no sign of the stone door opening.

Yanyan pointed to the "gossip" pattern on the operating table and said to Ding Xuecheng: "Bobo, you are the team leader, do you need to click on that flickering black dot?" ”

Kiki hurriedly nodded in agreement, and said thoughtfully: "It seems that the activity is not finished yet, maybe this is the last step." ”

Ding Xuecheng thought for a while and felt that it made sense, so he pointed his finger at the flashing black "fish eye" according to his words.

As Ding Xuecheng nodded, another question emerged under his fingers: "What is science?" ”

Ding Xuecheng suddenly realized and said to his friends: "This is a scientific illusion, of course, to answer questions related to science." There are two 'fisheyes' here, one is science, and the other may be 'metaphysics' that complements science. And what we are about to open now is the 'door of science', and we must know 'what is science'. ”

Ding Xuecheng didn't care whether the three friends were entangled in the "metaphysics" he had concocted, and replied loudly: "The answer to the question: Science is to observe and discover problems, ask questions, and ask 'why'; science is to use your brain and hands to study problems, answer questions, and explore 'why'." To be inspired by nature and life, to imagine, to create inventions, so as to serve the practice of life, this is science! That's it! ”

As Ding Xuecheng's last sentence fell, the black "fish eyes" on the stone gate no longer flickered, but emitted a dazzling light, and then the stone gate slowly rose, and a huge portal of 10 meters * 6 meters appeared.

The back of the stone gate was pitch black, and the friends hesitated, and they didn't dare to come forward to check.

Everyone was speculating in their hearts: maybe there was a deep tunnel behind it, and they didn't know where it leads; Maybe it's a huge stone chamber again, and inside the stone chamber is ......

(It's Christmas Eve, I wish my friends a safe year, everything goes well, and fortune and fortune!) …… In a few days, it will turn the moon and turn the year, and I am ready to apply for signing a contract on the first day of the new year, and it depends on everyone's help, hehe~ I wish us good luck together! ）
