As soon as Zhu Lang's question fell, the light screen flashed, showing four questions in a row:

1. How many pairs of fins do freshwater fish have? Where does it grow?

2. What kind of creatures do ants belong to? How many pairs of feet are there?

3. What is the difference between the front and rear legs of a hare? Why is the tail short?

4. Why can't I see the stars during the day?

Seeing everyone contemplating and thinking, Zhu Lang's old face was hot, and he secretly said in his heart: "Lao Tzu has to rely on these questions to complete the task and get points, but Lao Tzu is actually not sure about these primary school science knowledge...... Don't show your stuffing, otherwise when we meet today, we should say that we are only 7 years old, not 15 years old. ”

After the partners thought about it, Zhu Lang spoke first: "First the corresponding observer will talk about the idea, then everyone will discuss and supplement, and finally I will summarize." The first problem is in the river, and I have looked closely, and the small fish has a pair of fins under the gills (thorax) and a pair of fins near the vent of the abdomen, so it is two pairs. Do you have anything to add? ”

The three of them looked at each other with strange expressions, and Kiki tilted her head and said, "Who doesn't know, you still need to observe carefully?" There are two pairs of fins, and the role of the fins is to control the direction of the fish as it swims in the water, as we learned in science class! ”

Zhu Lang Zhengse said: "The knowledge in the books is a theory, we still have to verify it in practice, no matter how simple it is, seeing is believing!" ”

Everyone nodded, raised their eyes to look at the light screen, and a smiling face appeared after the first question. Everyone understood that the first question was answered correctly.

Yanyan stood up and said softly: "The second question is mine, I have looked at the ants carefully, there are a bunch of antennae on the head, 3 pairs under the body, 6 feet, one pair on the chest, and two pairs on the abdomen. Do you have anything to add? ”

"You haven't said what kind of insect it belongs to, it's an insect." Kiki added.

Zhu Lang looked at the expressions of the three people and said, "Ants belong to insects and have 3 pairs of legs. ”

The voice fell, and a smiling face appeared after the second question.

Kiki immediately jumped out and said hurriedly: "The third problem is mine, I can see clearly in the woods, the hare has short front legs and long hind legs, and like a frog, it jumps and walks. After speaking, he also learned to walk like a rabbit and jumped up.

Yeon-yeon: "Why is the rabbit's tail so short?" ”

Kiki said as a matter of course: "It's born like that, it's all short!" ”

"Did you get bitten off?" Yeon-yeon was a little unsure.

"No, I've read popular science books,...... But it doesn't seem to be said in the book, anyway, I don't think it's right. Captain, you say! Kiki retorted.

Zhu Lang knew the phrase "the tail of the rabbit can't grow", but why "can't grow", he really didn't think about it. He remembered Kiki's bouncing appearance just now, and a flash of inspiration flashed in his mind: "The rabbit's tail is too long, and it has a big tail like a squirrel, isn't it inconvenient to jump?" ”

"Aren't squirrels jumping too?" Bin Bin was entrusted with his chin to raise an objection.

Yanyan frowned and muttered, "Are all the long-tailed rabbits eaten?" ”

Kiki retorted again, "No, I've never seen a rabbit with a long tail!" Or rather, there is no rabbit with a very long tail. ”

"Unless the rabbit is trying to escape from predators, control its tail not to grow!" Zhu Lang had a whim.

"Haha, laugh at me, can you control your body from growing?" Bin Bin pointed at Zhu Lang and laughed so much that tears flowed out.

Zhu Lang was surprised that this 'Mu Mu Nan' seemed to be a little aimed at himself, so he asked rhetorically: "Tell me, what is the reason for the 'short rabbit tail'?" ”

"Uh~...... It's because of genetics...... Naturally, I agree with Kiki. Binbin didn't know the real reason, so he squeaked for a while, and finally supported Kiki.

Zhu Lang saw that there was no unified answer, but he couldn't help but answer, he gritted his teeth and said firmly: "Beibei, our answer is: the rabbit has short front legs and long hind legs, jumps forward, and in order to escape, he doesn't let his tail grow long." ”

As soon as Zhu Lang's words fell, a smiling face appeared behind the third question on the light screen.

"Yay~ Answer correctly!"

"Huh?"

"Oh~!"

"How is that possible? Can I politely deny it? Cut, you'll only guess, the blind cat meets a dead mouse! ”

"......, why does this baby have such a character? If you don't change in the future, Lao Tzu can't help but ......" Zhu Lang wanted to cry without tears, and shouted wildly in his heart.

Bei Bei commented in real time: "Congratulations to the prodigal son, the answer is correct!" It's good that science is inseparable from conjecture, and bold conjectures that conform to reality are necessary. 'Bold conjecture and careful verification' is also a scientific method. ”

Zhu Lang was a little disgusted with the 'Mu Mu Man', glanced at his 'sour wood' appearance, and said with a smile: "The last one is yours, how is it written in your popular science book?" ”

The three of them looked at Bin Bin in unison, his face turned red, and he stammered: "No, I didn't see this problem~ I think it's because the sun didn't shine on the stars, so I can't see it." ”

The two little girls didn't know the answer either, and looked at Zhu Lang, meaning to let him answer.

Zhu Lang had no way out, his brain turned sharply, "I can't see it, I can see it, I should see it but I can't see it......"

"Cut, I thought you could get it right again, it's not the same, what's the use of tongue twisters? Maybe my answer is right! "Binbin is very proud.

"By the way, do you think the actors in the stage lights can see the audience?" Zhu Lang asked.

Kiki imagined, "The lights don't reach the audience, of course they can't see it." ”

Binbin was even more proud, with the same pointed chin: "yes, it's still my answer!" ”

Yeon-yeon questioned, "Can people who aren't under the lights see the audience?" The audience can see each other~"

"This ......" Bin Bin and Kiki said at the same time.

"Beibei, my answer is: under the sun, the ambient light is too strong, far more than the light emitted by the stars, and the light of the stars is covered by the strong light, so it is invisible."

"Congratulations to the prodigal son, the answer is basically correct. The optic nerve of a person is stimulated by strong light and does not respond to low-light stimuli, so it cannot be seen. When Bei Bei commented, he also showed a smiling face after the last question.

After Bei Bei finished speaking, Binbin's face was flushed and he stopped talking; The two girls were jumping and jumping.

The light screen flashed again, and there were two more lines of words again:

"If the question answering session is completed, 800 team points will be awarded, each team member will be rewarded with a laser gun, and the captain's reward will be calculated separately."

"Submit the quest item."

"Wow~ There are also weapon rewards! Thanks to the captain's two efforts to turn the tide, otherwise he would not have gotten it...... Captain, you won't be able to get through if you answer incorrectly, right? What are the consequences of failure? Kiki jumped for a while, asking a question that made Bin Bin and Yeon Yeon stunned.

When Zhu Lang heard this, he was overjoyed in his heart, and secretly thanked this straightforward girl for asking a valuable question. He thought for a while, and said solemnly: "No matter which link fails, the task cannot be completed, all rewards will be canceled, and the team points will be deducted backwards, and the next trial event will cost points to open; Defeat three times in a row, eliminate the team, erase your memory, impaired consciousness, and become amnesia at least and vegetative at worst...... If you get injured or die in a challenge, the result will be the same! ”

Hearing this, the two girls lost their faces, and the 'sour wood man' was as earth-colored as the face...... They didn't expect that if a trial activity like an outing failed, the consequences would be so tragic, and their lives would be in danger! blamed themselves for their original frivolity.

"Bebe, take out the quest items."

With a wave of Beibei's short limbs, 'colorful coral', 'obsidian', 'azalea pollen', 'dead leaf butterfly', and 'purple coop' fell on the stone platform one after another.

The stone platform shoots out a light curtain to envelop the task item, and the light flashes, the item disappears, and lines of text are displayed on the light screen:

"Upon completion of the collection of mission items, 22,500 team points will be awarded, and each team member will be rewarded with a set of combat uniforms, and the captain's rewards will be calculated separately."

"Complete the event mission for the first time and reward the team skill 'Starlink'. [Note: This skill is a special skill for challenging the space team, which consumes team points, 100 points/time, and lasts for 10 seconds.] The effect is to ignore the signs, directions, and distances of the general barrier to mutual induction, with a range of 100 km. How to open: Mind 'Starlink, open!' ’】”

"The trial is over."

A minute after the last line of text appeared on the light screen, Zhu Lang's three teammates didn't have time to cheer, and they turned into points of light and dissipated, obviously returning to consciousness.
