Ding Xuecheng shouted loudly: "Beibei, the rules of projection activities." ”

……

The main light curtain lights up, and lines of text are displayed.

Main quest 2: [Intermediate] Scientific Inquiry.

Side quest 1: Prologue

Quest Activity: Open the door to science.

Activity rules: Select the two hexagrams of the "Gate of Science", and press the selected hexagram positions on the left and right palms respectively to activate the question; If you answer the question correctly or the experiment is successful, the hexagram will be opened and you will receive the corresponding reward; When all the hexagrams are opened, the "Science Gate" of the intermediate activity space is activated.

Qiqi blinked her eyes wide, looked at the stone gate, and screamed: "Such a high stone gate, you can't reach the hexagram on the pattern~ What should I do?" ”

The eyes of the other friends were also between the words of the light curtain and the stone gate, scanning back and forth, a little dazed.

Ding Xuecheng could only ask Bei Bei for help: "Bei Bei, we can't reach the desks and chairs~ How can I press it?" ”

"Hey, no need to climb up! As soon as the activity time came, an operating table rose in front of the stone gate, and the handprint was pressed on the screen of the operating table. Countdown: 10, 9, 8, 7...... 3, 2, 1, on! ”

With the sound of Beibei's "opening", a stone platform slowly rose in front of the stone door, the size of a desk. The friends "hula" and surrounded them.

Kiki touched it curiously and said, "Isn't this just a stone platform?" How to use it? ”

Yanyan walked around the stone platform and said in surprise: "There is no display, how can it be called 'operating table'?" Where to press the mudra? ”

Bin Bin tapped everywhere on the surface of the stone platform, wondering, "Is it a central computer?" It's just made of stone. ”

"Where's the electricity here? Certainly not a computer! I'll give it a try. Ding Xuecheng said, pressing his right hand on the stone platform.

The moment Ding Xuecheng's palm was pressed, the stone platform seemed to be electrified, and a light blue light flashed on the surface; Bagua patterns appeared on the countertop, exactly the same as the patterns on the stone door, but they were many times smaller.

Ding Xuecheng hurriedly withdrew his hand, looked at the three stunned friends, and explained: "Hehe, maybe I'm the team leader, so I can activate the console." Let's think about which two hexagrams to choose. ”

"I don't know where to start~ There is no problem prompt above, I don't know if the problem of choice will be. What should I do if I choose the wrong one? ”

"You see, there is no rule in the rules of the event that you are not allowed to communicate and discuss, you won't, we will teach you."

"Didn't you say there were experiments? There's no lab equipment here! ”

"I remember a little bit of 'Bagua' knowledge, Qian represents the sky, Kun represents the earth, Xun (xùn) represents the wind, Zhen represents the thunder, Kan represents the water, Li represents the fire, Gen (gèn) represents the mountain, and Dui represents the ze. We have two men and two women, Qian, Zhen, Li, and Gen are yang, suitable for men; And Kun, Xun, Kan, and Dui belong to Yin, which is suitable for women. Everyone's personality is different, and their attributes are also different, for example, Kiki and Yeon-yeon are both female, but Kiki is lively and Yeon-yeon is quiet, then, Kiki chooses Xun and Dui, while Yeon-yan chooses Kun and Kan; In the same way, I choose Zhen and Li, and Bin Bin chooses Qian and Gen. What do you guys think? ”

"Isn't 'Qian' the starting point? You're the team leader, you should choose 'dry'......"

"I think like that, I don't know if it makes sense, the key is to answer correctly or the experiment is successful, it doesn't matter how you choose."

"Oh~Then let's try it~"

After Kiki finished speaking, she raised her hands and pressed them against the "Xun" and "Du" positions. A question appeared on the left and right palms of her hands: "Curiosity is the starting point of science, try to ask 3 questions like a scientist." "How does the Internet help us learn about science?"

Qiqi looked at the problem and said embarrassedly: "It's not difficult to ask questions, but I'm afraid that the question of 'network' will not be good~ You teach me!" …… Bobo, can I withdraw a hand? ”

Ding Xuecheng said angrily and funny: "Who told you to put your two hands up at once?" Come one by one~ I don't know what to do. Babe, what now? ”

"You can't take your palms away, otherwise you're a failure! …… Say the hexagram first, and then answer; When you're done, say 'Answered'. ”

The four of them asked in unison, "What happens if you fail?" ”

"Failed, of course, this event ended here, I couldn't open the 'door of science', and the intermediate activities in the back couldn't be carried out, and the 200 points this time were also spent in vain."

When the three friends heard this, Kiki was startled and blushed for her recklessness.

Ding Xuecheng shouted: "Beibei, intermediate activity, isn't it 50 points once?" How did it become 200? ”

"Aren't they your buddies? 'Tickets' are also required! ”

“……！ There are pits everywhere~ It's too treacherous! …… 200 is 200, I endured it and confessed it...... Give me points to earn, the days will be long in the future, 'the landlord's family has no surplus grain'......"

Ding Xuecheng took a deep breath and said to Qiqi: "I have studied all these contents, I said the answer, you heard it clearly, and then repeated it." Make no mistake, otherwise, if someone answers incorrectly, the points will be wasted. ”

The three friends looked at Ding Xuecheng in a daze, and asked in unison, "What did you and Bei Bei say?" What is a 'ticket'? What is a 'Credit'? ”

Ding Xuecheng regretted discussing this issue with Bei Bei in public, and blamed himself in his heart: "Bei Bei, I shouldn't have said it." Now what? Do you want to be honest with them? ”

"There's no need. They can't earn points on their own, and they can't use them. You can deal with the past casually, and compensate them later, for example, if there is a surplus of points in the future, or they are in urgent need, you can exchange it for enhancement liquid, culture solution, etc. for them to use. ”

Ding Xuecheng patted his forehead, took the opportunity to organize the language, and said to the three friends: "Every time you complete the activity task, according to the evaluation, there will be corresponding points reward, and use the points to open the activity task, 50 points per person each time, so if you fail this time, 200 points will be spent in vain." ”

Binbin asked without giving up, "How many points do we have?" ”

"Uh~...... It used to be a low-level task, and the points obtained each time ~ were very small...... It's enough to buy a 'ticket'...... In the future, when you have enough points, you can exchange them for some items that enhance your physical attributes and use them for everyone, so you have to work hard to earn points in the event. ”

"Bobo, let's solve my problem~ My arms are sore!" Kiki screamed.

Ding Xuecheng was afraid that Binbin would continue to ask, so he hurriedly told Qiqi the answer.

Kiki cleared her throat and said solemnly: "Answer the question of the exchange of positions: Scientists are people who love to think and ask questions. Great scientific discoveries often begin with questions, and curiosity is the starting point of science. There are many, many questions in the world of science, such as why do birds fly freely in the sky? Why do people feel lighter in water? Why does the sun always rise in the east? Why can geckos crawl freely on smooth glass windows? …… That's it! ”

As soon as Qiqi's words fell, the "exchange" on the huge stone door lit up, the runes flowed, and the colored light shone.

Kiki withdrew her left palm, cheered with everyone, and immediately said: "Answer Xunwei's question: On the Internet, there is a 'Primary Science' website, which has a variety of multimedia resources. Here, we can collaborate with children from all over the country and even the world to learn, explore independently, and interact with each other...... This is the world where we can gallop freely. That's it! ”

Everyone was pleasantly surprised to see that the "Xun position" on the stone gate was lit up again.

Kiki stuck out her tongue, withdrew her right hand, breathed a sigh of relief, and secretly warned herself: "You can't be so reckless in the future, if you don't get it right, you'll drag everyone down!" ”
