This wind tunnel of the Ministry of Magic combines the elements of technology and magic, which can do things that ordinary wind tunnels cannot do, and simulate various complex airflow conditions, such as ** explosion waves.

This wind tunnel is half the size of a football field, built with cement, and the whole is rectangular, with round curves at the corners.

Zhou Zhou was holding a sword in his right hand, standing in the middle of the wind tunnel, looking around, and saw detergent, newspapers, seats and other debris on the ground in front of him.

Rachel believes that to simulate the real situation, it is best to put some things that will be found in the real situation. In some special situations, these miscellaneous things are powerful tools for killing people.

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

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

Rachel's voice came from the magic loudspeaker in the corner: "OK, target: reach the target, now start the mind power mode."

"Hey! I'm not ready yet!" As soon as he finished speaking, Zhou Zhou fell into trouble by the strong wind coming towards him.

He was half-kneeling, landing like a beast in all limbs. He grabbed five fingers with his left hand into the concrete floor, and almost lying on his face and rubbing forward little by little. His face was facing the ground and he couldn't look forward. The strong wind blew him so hard that he couldn't open his eyes.

"Are you a turtle? If the enemy was Carrie, you would have died long ago!" Rachel's loud accusation came from the loudspeaker.

Zhou Zhou reluctantly raised his head, and a bottle of detergent hit his face head-on, and many small bubbles were blown out. Zhou Zhou was surprised to find that some of the bubbles were actually retreating in the opposite direction under the strong wind and flying towards the target!

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

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

The wind stopped and the buzzing of the big fan engine on the wall quieted down.

"Retreat twenty meters. Continue."

"Come back!" Zhou Zhou was startled and quickly stood up. He rushed for 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 would not be firm and would be easily blown away.

But if you stand firm, the speed will be very slow.

In this way, he advanced ten meters and retreated ten meters. He practiced for a whole morning without any progress.

Zhou Zhou got up from the ground panting and made a pause gesture.

Rachel's voice came from the corner: "I'll let you rest in the last group. It's too boring to use the mental power mode all the time. Now I'll have a little internal power mode, and the eighteen palms of the dragon subduing, and the Kanglong regrets it to start."

Then a dragon sounded in the wind tunnel, and Zhou Zhou was once again squeezed into the wall by the airflow, and a mouthful of blood was spurted out.

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

"Eighteen Dragon Subduing Palms?! What do you think? Have you seen it? Just do it." Zhou Zhou said weakly.

"Didn't you take a picture of you on the wall at once? I studied various explosive explosions and calculated and simulated them based on the descriptions in Jin Yong's novels. The dragon's mind is exactly the same as in the TV series." Rachel argued.

"you…………."

"Shut up!" Laura angrily said, "Let's go for a meal."

Zhou Zhou practiced for one morning and felt his stomach empty, so he raised his hands to agree.

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

"I suddenly thought of one thing, why don't we get the interstellar spaceship from the movie world, but we have to build it ourselves? For example, Star Trek, Interstellar Travel, Alien Series, Iron Man, and Galaxy Guardians all have interstellar spaceships, and the technology inside is also very good?" Rachel said with a small mouthful of fries.

Zhou Zhou swallowed a mouthful of hamburger and said, "Actually, we have been doing what you mentioned. Collect magic biotechnology and magic space technology. But we have not yet encountered a movie with a starship. If we encounter one, we will collect one, and if we encounter two, we will collect two. But because we may encounter alien movies or Iron Body in the future, we will give up collecting magic biotechnology and magic space technology?"

"I don't mean that. Of course, these technologies need to be collected, but since you can get a starship from the movie world, why do you have to spend so much effort to build this magic spacecraft, and this plan to build your own starship. Isn't it a bit unnecessary? Are you right? Laura." Rachel suddenly looked at Laura who was eating chicken nuggets silently on the side.

"This——If we had no plan to build a starship, would we still think of building this wind tunnel? Will we think of collecting magical biotechnology and magical space technology?" Laura asked and answered himself: "I think it probably won't. Zhou Zhou couldn't have an idea out of thin air."

Zhou Zhou continued: "We will definitely not let go of any interstellar spacecraft that appears in the movie world, but I will not give up the idea of ​​building a spacecraft on my own. Because this is a very beneficial thing. Just like a big country will invest in aerospace engineering, it seems that there is no use besides throwing satellites and various probes into the sky. However, these studies can indirectly promote scientific and economic development, which is much more meaningful than demolishing houses to build houses. The meaning of our construction of spacecraft is for these indirect benefits."

"Well, I hope the harvest will be greater than the energy we put in." Rachel said with a wrinkle: "But there are seed banks in movie worlds such as Harry Potter. Why do we need to collect seed banks in the main world?"

Laura looked at Zhou Zhou.

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

"So you're sure you want to collect the seed bank of Harry Potter World?" Rachel stared at Zhou Zhou with big brown eyes.

"The world's seed bank is not spared, and the seeds from the wizard world must be collected. After the shamans and the others obtain space technology, they will start collecting them." Zhou Zhou said.

"There is also a gene bank that is so close that we forgot to collect." Laura suddenly said.

Zhou Zhou and Rachel both looked at her.

Laura said: "The genes of the wizard.

Two days later, the Ministry of Magic employees went to St. Mungo Hospital for a medical examination.
