"This is our secret weapon to defeat the space team!" Klopp said, pointing to the mysterious square building behind him.

Hearing the head coach's words, the doubts in everyone's eyes are even stronger.

How can you defeat the secret weapon of Barcelona in this seemingly ordinary house?

This is a house with no windows. Everyone can't imagine what this kind of house can do besides being used as a warehouse.

The answer was revealed later.

When Klopp led the players into this "big" black house, the first thing that caught his eye was a huge iron cage.

Inside the iron cage is a piece of artificial turf. There is a circle drawn by a white line in the artificial turf, just like the middle circle of the stadium.

There are many lights above the roof into the cage, so although it is in a dark room with no windows, the cage is as bright as the day.

The middle part around the iron cage has two square holes on the upper and lower sides, and there are four holes on the four walls, a total of eight holes.

All this looks very confusing and strange.

Everyone looked at what they saw with curiosity, and didn't quite understand what it was for.

Zhou Yi thought of an advertisement that Nike once shot, the iron cage scorpion, so he asked: "Coach, do you want us to be one-to-one in it? The losers will be thrown into the sewer and rushed into the Rhine ..."

The teammates burst into laughter.

"I really want to do this, kid." Klopp also smiled.

Just kidding, he clapped his hands and pointed to the iron cage to introduce to everyone here: "Welcome to'footbonaut'!"

Hearing this name, everyone was still confused: "What is that stuff?"

"As you can see, in front of you is a square area that is 14 meters long and 14 meters wide. The walls in this area are composed of 72 special wall panels. Have you seen this?" Clo Pu pointed to the white hole and asked.

Everyone nodded.

Klopp asked again: "Does anyone play table tennis?"

Some people in the team raised their hands, and Zhou Yi raised the highest-as a player from China, this aspect must be confident.

Klopp saw him and asked him: "Zhou Yi, have you been in contact with the table tennis ball machine?"

Zhou Yi shook his head: "No, but I have seen it. It is a machine that continuously shoots table tennis, and then the table tennis player catches the ball on the opposite side..."

"The explanation is very good." Klopp nodded. "And this." He pointed to the white hole and said, "That's our serve machine!"

Hearing this, Zhou Yi could guess how this mysterious and strange thing was doing...

Klopp continued to explain to the players: "You need to receive the **** from these servers in this white circle, stop the football, and then kick the football towards the randomly lit grid. Sounds simple. wrong?"

Zhou Yi nodded habitually, then Klopp stared: "Hey, Zhou Yi."

"Ah?" Zhou Yi didn't think he would be named, he was a little confused.

"Come on, let's make a demonstration for everyone!"

"Oh!" The teammates next to them blew their excitement in excitement, and they wanted to see Zhou Yi's appearance. Obviously, when Klopp asked "very simple", the answer he wanted was definitely not "yes." Zhou Yi was equal to hitting Klopp's muzzle himself.

Zhou Yi was rushed into the iron cage. After entering the cage, the door was closed.

"Go to the middle circle," Klopp said outside, pointing to the white circle.

Zhou Yi walked in obediently, and then started looking away, his head swaying from side to side, printing everything he saw in his mind, this is his habit, in a strange place, he will continue to observe Scan and record every detail of this environment.

"Are you all right?" Klopp asked outside.

Zhou Yi gave Klopp his thumbs up.

The teammates outside stood smiling, waiting to see Zhou Yi and the machine duel.

"Okay, count down three seconds." Klopp finished.

The seventy-two grids in the cage suddenly turned on red lights at the same time, which surprised many people.

Next, after one second, the red light turns yellow, and after another second, the yellow light turns green.

After the green light goes out, two sounds similar to the prompt sound when the car locks the door.

Zhou Yi heard the sound coming from behind him, so he turned his head and looked back, and saw a football burst out of a tee with red light!

Zhou Yi quickly turned around and turned halfway, and the football hit his supporting feet!

A stagger, he fell to the ground!

There was coquettish laughter among the teammates.

"Get up!" Only Klopp yelled at Zhou Yi. "Get up!"

As soon as his voice fell, two more prompts sounded.

As Zhou Yi raised his head, he saw a football shot from another server and flew towards him. He reflexively blocked his face with his hand. The football hit his arm and spread out.

Seeing Zhou Yi so embarrassed, the teammates outside laughed back and forth.

However, Zhou Yi also realized that the machine did not seem to be suspended because of his fall, so he quickly jumped from the ground this time, and he already knew how the machine worked.

The two beeps are to remind the player that the football is to be fired from the hole in the direction of the beep, which will be about a second earlier than the pass, allowing the player to turn ahead and prepare.

So this time when the beep sounded again, Zhou Yi immediately determined that the football would come from his right side, so he quickly turned around and faced there.

Sure enough, the red light outside the tee below the right side turned on, and a football was launched.

Zhou Yi raised his leg to stop the ball. He stopped the football obediently and raised his head. He found a green light around the grid on the left wall.

Zhou Yi quickly passed the football, the football accurately hit the grid, turned the grid up, and rolled out.

Then the grid automatically flips back.

Immediately after that, there were two cue sounds again. This time from Zhou Yi's back, he turned around, the football flew over and raised his leg to stop the ball. After stopping, he looked up and saw a light on a grid facing him. Zhou Yi kicked the football over and the football hit the ball again accurately.

The third time, after Zhou Yi passed the ball, the football bounced back on the grid and the green light turned into a yellow light.

Zhou Yi ran out of the circle and kicked the football towards the grid again. When the yellow light turned into a red light, the football finally successfully hit the correct goal.

In this way, every time there is a prompt sound, Zhou Yi will quickly turn around to complete the catching action, and then repeat the whole set of catching and passing actions.

In the process, he found that the speed of the target grid changing from green light to yellow light and then to red light is very fast. It may be two seconds after the three lights are turned on. He must kick the football to the goal in such a short time.

After playing at the same time, the pass tone will sound immediately. Zhou Yi hardly gives Zhou Yi any chance to take a breathing break. He must circulate this set of movements without interruption, and the whole person can't stop or stop.

However, this fast-paced training makes Zhou Yi have an addictive feeling in the process...He has completely ignored it and considered other things. He is fully absorbed, and all his energy is concentrated on finding goals, receiving and passing.

And the teammates outside the cage gradually stopped laughing, and the expression on their faces became more and more serious, because they also discovered that this thing is not a fun toy, the content and training shown in Zhou Yi's demonstration The intensity makes many of them have to take this strange iron cage seriously...

They are all professional players and they know exactly what this series of quick passing and receiving means.

Just when Zhou Yi had entered the state of ecstasy, the two beeps did not sound again.

Zhou Yi turned around and looked around. The eight white serve machines never lighted up.

"Huh?" He hadn't figured out what was going on.

Klopp opened the door and came in: "It's over."

"It's over?" Zhou Yi's unbelievable expression, he hasn't been addicted yet.

"Well, one and a half minutes of a single training," Klopp explained.

"Ah, can I come again? Coach?" Zhou Yi begged.

"Do you think this is for you alone? They can still wait!" Klopp pointed to the players outside the cage.

Zhou Yi looked at ~lightnovelpub.net~ and found that the eyes of his teammates were as excited and eager as he was. Everyone seems to be deeply attracted by this novelty!

Of course he could not dominate the training facility, so he had to leave the cage with regret and unsatisfaction, and gave the position to other teammates.

Watching the teammates excited and awkwardly adapting to this brand new training facility in the cage, Zhou Yi felt itchy.

He couldn't help but wonder how good it would be to have a training facility of his own...

On this day, the Dortmund team, except for the goalkeeper, all had a total of ten minutes of "footbonaut" training.

Zhou Yi is also the same, but at the end of training, he still bid farewell to this "big" black house with a reluctant mood.

As he walked out with his teammates, Zhou Yi looked back at the building with white windows and no windows.

He is seriously thinking about whether he can sneak back at night for special training... (to be continued.)
