This wind tunnel of the Ministry of Magic combines elements of technology and magic, and can do things that ordinary wind tunnels can't do, simulating all kinds of complex air flow situations. For example, the blast wave.

Half the size of a football field, the tunnel is made of concrete, and has a rectangular shape with rounded curves at the corners.

Zhou Zhou, holding a sword in his right hand, was standing in the middle of the wind tunnel, looking around, only to see that there were detergents, newspapers, chairs and other miscellaneous items on the ground in front of him.

Rachel thinks that in order to simulate the real situation, it is better to put on something that will be in the real situation, and in some special cases, these miscellaneous objects are murderous weapons.

Directly opposite Zhou Zhou, past these debris, about fifty meters away from Zhou Zhou, stood an iron rod, and on the upper part of the iron rod was a concentric iron target.

"Don't you need to put a model to test first?" Zhou Zhou said loudly.

Rachel's voice came from the magic speaker in the corner: "OK, goal: to reach the target, now activate telekinesis mode." ”

"Hey! I'm not ready yet! As soon as the words fell, Zhou Zhou was blown away by the oncoming strong wind.

He was half-kneeling, on all fours like a beast, and the five fingers of his left hand were caught in the concrete floor, almost lying on his stomach and rubbing forward a little, his face facing the ground, unable to look forward, and the wind blew so that he could not open his eyes.

"Are you a turtle! If the enemy was Carrie, you'd be dead! Rachel's voice was heard over the loudspeaker.

Zhou Zhou barely raised his head, and a bottle of detergent hit him head-on, blowing up a lot of small bubbles. Zhou Zhou was surprised to find that some of the bubbles were actually retreating in the opposite direction under the strong wind, flying in the direction of the target!

Zhou Zhou immediately adjusted the scarce internal force in the group, trying to build an arc-shaped qi wall outside the body, but his internal force was really pitiful, and he could only barely send it out of the body, and then immediately dissipated.

Zhou Zhou was blown away, like a fly, and was slapped against the wall by the wind.

The wind stopped, and the hum of the big fan engine on the wall fell silent. "Twenty meters backwards. Go on. ”

"Come back!" Zhou Zhou was startled, quickly stood up, and rushed twenty meters while the wind tunnel had just started and the wind was not strong, and then was blown back. Gradually, he found that if he wanted to run fast, his feet were not firm and he could easily be blown away.

But if you stand firm, it's slow.

In this way, he went forward and backward ten meters, practiced all morning, and there was no progress.

Zhou Zhou got up from the ground out of breath and made a pause gesture.

Rachel's voice came from the corner, "Let's let you rest at the end of the group." It's too boring to use telekinesis mode all the time. Now let's take a little internal force mode, descend the dragon eighteen palms, and Kanglong has regrets to start. ”

Then the sound of a dragon roaring sounded in the wind tunnel, and Zhou Zhou was once again squeezed against the wall by the air current, and a mouthful of blood spurted out.

Seeing that something was wrong, Laura outside the wind tunnel immediately stepped forward to close the wind tunnel, rushed into the cave, and helped Zhou Zhou out.

"Eighteen Palms of the Dragon?! What do you think, have you seen it? Just fool around. Zhou Zhou said weakly.

"Didn't you slap you on the wall all at once? I studied all kinds of explosive explosions, and calculated and simulated them based on the descriptions in Jin Yong's novels. That Long Ming is exactly the same as in the TV series. Rachel argued.

"You're ............."

"Shut up, y'all!" Laura angrily retorted, "Let's go eat." ”

Zhou Zhou practiced all morning, and just felt that his stomach was empty, so he raised his hands in approval.

They came to the ground together, found a McDonald's and sat in, and ordered a family bucket.

"One thing suddenly occurred to me, why don't we get a starship from the movie world, but build it ourselves? For example, Star Trek, Interstellar, Alien series, Man of Steel, and Guardian of the Galaxy all have starships, and the technology in them is also quite good, huh? Rachel said as she took a small bite of her fries.

Zhou Zhou swallowed a bite of hamburger and said, "Actually, we have been doing what you mentioned. Collect magical biotech, magical space technology. It's just that we haven't come across a movie with a starship yet. If we come across one, we will collect one, and if we come across two, we will collect two. But because you may encounter an alien series of movies or Man of Steel in the future, will you give up collecting magical biotechnology and magical space technology? ”

"That's not what I meant. Of course, these technologies have to be collected, but if you can get a starship from the movie world, why do you need to spend so much effort to establish this magical space department, and this plan to build your own starship, isn't it a bit redundant? Are you right? Laura. Rachel suddenly looked at Laura, who was silently eating chicken nuggets.

"If this ——— hadn't had a plan to build a starship, would we still think of building this wind tunnel? Would you have thought of collecting magical biotechnology and magical space technology? Laura asked herself and replied: "I don't think so, Zhou Zhou can't have an idea out of thin air." ”

Zhou Zhou took up the conversation and said: "We will definitely not let go of any interstellar spaceship that appears in the movie world, but I will not give up the idea of building my own spaceship." Because that's one of the things that is very beneficial. It's like the big powers will invest in space engineering, and it seems that there is no use for anything other than throwing satellites and various probes into the sky. But these studies can indirectly promote science and technology and economic development, which is much more meaningful than tearing down houses and building houses. The purpose of our spacecraft is to build these indirect benefits. ”

"Alright then, hopefully the harvest will be greater than the effort we put in." Rachel paused and said, "But there are also seed banks in the movie world, such as the Harry Potter world, why should we go to the seed bank of the main world to collect them." ”

Laura looked at Zhou Zhou.

Zhou Zhou raised his eyebrows and said, "Look at what I'm doing!" Didn't you think of it either? ”

"So you're sure you're going to collect the Harry Potter World Seed Bank?" Rachel's big brown eyes stared at Zhou Zhou.

"The seed banks of the world are not spared, and the seeds of the wizarding world must also be collected. When the shamans have acquired space technology, they will start collecting. Zhou Zhou said.

"There's also a gene pool close at hand, which we forgot to collect." Laura said suddenly.

Zhou Zhou and Rachel both looked at her.

Laura said, "Wizard's genes.

Two days later, the Ministry of Magic employees all went to St. Mungo's Hospital for a medical check-up.

The Ministry of Magic has also invested a sum of money in St. Mungo's Hospital to encourage wizards to come for free medical check-ups.
