Binbin didn't interject, as if the questions were too simple, and he didn't bother to rush to perform.

When the critical time came, seeing that everyone couldn't answer, it was time for him to show his 'basic skills', and explained loudly: "The wing of the fixed-wing aircraft is designed to imitate the bird's wing, the front edge is thick and then thin, and the lift is generated when the height is thrust forward. ”

He paused, looked around proudly, and continued: "Airplanes were developed on the basis of bird flight, and compared with the two, each has its own advantages. Aircraft have advantages in speed, altitude, persistence and load capacity. And the agility of birds is incomparable to that of airplanes. Birds can take off and land in more situations, can turn at any time, and perform a variety of difficult maneuvers, and hummingbirds can fly upside down, which is incomparable to airplanes. So, we have more to learn from birds, they give us more inspiration, they are our mentors and friends. ”

", there is this knowledge in physics in the third year of junior high school, but I haven't reviewed it yet, so I forgot it! was given the upper hand by the 'sour wood man'......" Zhu Lang secretly blamed himself, but he still had to give fair praise to the performance of the 'sour wood man': "Well, Binbin said it very well. One last question, when the sun comes out after the rain, sometimes you can see a rainbow. ”

Kiki raised her hand: "You can see it next to the fountain when the sun is out." ”

Yanyan followed: "At noon when the sun is out, go to the fountain in front of the building or square, and you can see it there." ”

Binbin questioned: "Then why can't you see it sometimes?" ”

Zhu Lang and the two girls, you look at me, I look at you, I don't know very well. Kiki thought for a moment and said, "Angle......

With a look on his face, like a singing actor, he shook his sleeves and said: "Rainbows can usually be seen in the sky after rain or in places where there are waterfalls, because there are many small water droplets in the air at that time, and this phenomenon is more obvious. Since the small water droplets gather to form a Mitsubishi mirror structure, the white light of the sun is refracted in the water droplets, causing it to disperse into seven monochromatic lights, so a seven-color rainbow appears. And because the refractive index of red light is smaller than that of violet light, the outer layer of the rainbow is red and the inner layer is purple. One must stand between the sun and the rainbow and face the rainbow in order to see the rainbow, i.e., the rainbow appears on the opposite side of the sun—the morning rainbow in the west and the evening rainbow in the east. ”

……

"Okay, I'll summarize the answers to these questions, turn in the quest items and pollen exchange, and this event is complete."

Zhu Lang sorted out the answers to the three questions, and then answered them one by one, and this time he won 50, 10, and 30, for a total of 90 team points. A bionic insect detector was also awarded.

Several teammates were depressed when they saw that they had won so few team points this time. But when I saw the 'Bionic Insect Detector', my eyes lit up, and when I heard that I had to hand over mission items and exchange pollen, I hula and all of them gathered around.

Zhu Lang instructed: "Beibei, hand in the mission items." ”

Bei Bei took out six lockets and placed them on the stone platform. The light curtain is swept over, the items disappear, and the result is displayed on the task light curtain: collect the task items, overcomplete, and add 20% team points reward, a total of 720 team points; A bottle of hallucinogenic potion will also be rewarded.

Zhu Lang instructed again: "Beibei, exchange the pollen for points." ”

Bei Bei took out six more lockets and placed them on the stone platform. Everyone stared at the light curtain, and immediately saw the results: collect materials related to mission items, exchange them for 6,000 team points, and contribute 6 points; A bottle of hypnotic potion will also be rewarded.

The teammates cheered for the 6,000 team points and a bottle of potion for this event, and the two girls praised the 'Captain Wise', and the 'Sour Wood Man' also died down, after all, his team contribution this time was not great.

Zhu Lang announced that at the end of this event, Bei Bei projected two lines of large characters on the light screen:

"Curiosity is a valuable psychological quality for teenagers."

"I have no other talents, I just have a strong curiosity; I don't have any other talents, but I like to get to the bottom of things. - Albert Einstein. ”

After the consciousness of the three teammates returned, Zhu Lang immediately checked his character attributes.

Zhu Lang was about to complain to Bei Bei that "points are difficult to obtain" because of the small number of personal points he gained this time, and when he saw the final reward, he almost cried with gratitude: "Ah~ Tracking!" It's another universal skill, super practical, and it doesn't consume luck points! …… Nima, it shows 'inactive' again, and Lao Tzu's personal points have to be 'high diving' again! Bebe, how much will it cost this time? …… Hey? How can a clan skill be used without activation? ”

"This skill is not very powerful, it is just a minor technique, and it takes 10,000 personal points to activate the 'tracking technique'. Clan skills are clan benefits and do not need to be activated. Bei Bei looked very indifferent, as if he was disgusted with Zhu Lang's sluggishness, and it took so long to find this difference.

Zhu Lang felt that 10,000 points was far lower than his psychological expectations, so he spent 10,000 points to activate the 'Tracking Technique' skill. He secretly slandered to himself: "Dead dog, there is no point commission to take, this time I only got the 50 points promised by Lao Tzu, no wonder it is like a frosted eggplant!" …… Made, this dead dog is too much, and he didn't even ask, and he settled the account......"

Suddenly, Zhu Lang saw the team reward and became excited: "Beibei, do I have the authority to use the team's equipment?" The bionic insect detector and those two potions are super useful! ”

Bei Bei said with certainty: "You are the captain of the clan, and the entire clan is yours, so you are naturally qualified to use it." The vast majority of consumables will appear in the redemption list as soon as they appear. When you want to replenish your consumption in the future, you can redeem it here. ”

"Hurry up and take it out and transfer it to me, be prepared. …… Lao Tzu's storage bag is a bit small, so I have to find a way to repair some of the orbs and use them to store items. Zhu Lang was overjoyed and complained impatiently while collecting the items.

Bei Bei reminded: "The space of the orb is unstable now, it's best not to put things in it, lest the orb collapse and the things you put in it will also be gray." ”

Zhu Lang was shocked: "So serious? To what extent can I use it? ”

"I don't know. But I guess that the orb no longer emits a faint golden light, but the golden light has become stronger, and it will probably be ready to use. ”
