The 600 people who had been taken out of the city by Langdon had not seen what they were when the batches of supplies were supposedly for screening and training them, and when they had assembled some of them by hand, they still didn't know what they were for.

It is a large frame made up of countless large squares, the large squares are not exactly the same, there are squares, there are rectangular, 6 large squares can be put together into a completely hollow cuboid.

The cuboid is large enough for 5 to 10 people to stand in it without feeling cramped.

And then these cuboids are further spliced together to form this huge framework that presents the box.

Of course, this huge frame is not completely hollow, in fact, except for a small number of large squares, the vast majority of the large squares that make up the frame have things embedded in them.

To the 600 candidates, it was nothing more than a fist-sized ball of iron tied to two ropes connected to each end of the box.

The 600 candidates were of course full of doubts about the huge shape of the frame, which was not strange but still confusing, and some people were trying to figure out what it was used for, and some even took those things and joked with others.

However, this behavior soon stopped with Langdon's words, "I advise you not to be too curious about these things, otherwise, when you scream and wail and cry in here, and think of what you have done now, you will hate yourself very much, and hate yourself for having completed it." ”

Langdon's tone was lighthearted, like a joke, but no one thought he was really joking, it was a soldier's job, and there was no room for half a joke.

Soon, as Langdon ordered the first candidates to enter the frame, they finally understood the purpose of the frame, and at the same time, they finally understood the meaning of Langdon's words.

The 600 candidates were divided into 12 groups of 50 each, and under Langdon's orders, the first group quickly entered the frame, and according to Langdon, they did not try to stand in a queue again, but dispersed and found a place that they felt was good.

Langdon then picked out a few more groups from the remaining candidates and scattered them around the frame to stand.

Until this time, both the people inside and outside were still confused.

Then, as Langdon walked over to a box, grabbed the iron ball that was suspended by two ropes in the center of the box, and pulled back.

He pulled the iron ball out of the box, and pulled it out of a long distance—the two ropes turned out to be elastic.

Then, Langdon said to the person closest to him in the frame, "Be careful. ”

Before the man understood what Langdon meant, he was about to ask with a confused expression, when he saw Langdon suddenly let go.

With a soft buzz, I saw the iron ball come out of Langdon's hand and fly out at an alarming speed!

And the direction in which the iron ball flew out was exactly the direction where the man was!

The man was shocked and hurriedly ducked to the side, but the iron ball was so fast that he only moved half a position before the iron ball reached him and smashed his arm.

"Ahh

A scream, of course, came from the person who was hit, the iron ball was not small, and the speed was so fast, of course the damage caused would not be weak.

The man clutched his smashed arm, and was about to pull up his sleeve to see how he was injured, but at the same time, the iron ball that hit him did not stop, but was pulled out by the bungee cord, until it was close to Langdon, and turned again, and threw it at the man again.

"Ahh

Another scream, but this time it wasn't a scream, but an exclamation, the man was also clever, and he didn't really stand in place to see the injury, and at the same time he kept an eye on the iron ball, and at this time he saw the iron ball flying again, and hurriedly spread his steps to escape, and finally he was not hit again.

The ball smashed into the air and returned again, this time Langdon didn't let it bounce away, but reached out to catch it and put it back in place.

"So, now you understand what this thing does?" Langdon asked.

"Understood!" replied in a voice that was not as loud as before, and a little weak.

There were no fools who could be chosen, after such a demonstration, they already understood the purpose of this thing, and hearing the scream just now and seeing the man's smashed red and purple arms made them all nervous.

"Very good, since you understand, then I will not have to explain, then, the first stage of screening preparation begins, 200 people, 200 balls, the iron ball every 3 times back and forth, or hit the human body twice to stop and recharge, time, first tentatively set for 3 minutes. So, let's get started!" Langdon said the rules briefly, and then, with a command.

The frame was large enough to accommodate 50 people, but when the 200 iron balls on the periphery were also added, the space suddenly became insufficient!

When there is only one iron ball, most people only pay attention to the lethality of the iron ball, and almost everyone thinks that it is not difficult to dodge the ball, but when the number of iron balls suddenly increases to 200, the situation is completely different.

The design of the frame is very exquisite, no matter where those people choose to stand, there will definitely be an iron ball that can hit him, and most of the time, there will not be only one iron ball flying towards the person, but several iron balls from different directions, and this alone is more difficult to dodge than a single iron ball.

In addition, 50 people stand in the frame, because they want to dodge the iron ball, almost all of them are moving, but the movement trajectory is different, and it is very likely that there will be a collision, and once the two people collide, their dodge will inevitably be affected and hit by the iron ball, so while dodging the iron ball, they also have to avoid other people, so the difficulty increases again.

What's more, at this time, the person who serves outside is not Langdon, but other alternatives, and there is a direct competition with the person who dodges inside, of course, they will not show mercy, every serve almost uses all their strength, and specifically aimed at people, which virtually raises the difficulty of dodging a big notch.

Just the superposition of these difficulties is enough for the people in it to drink a pot, not to mention the problems such as the change of direction caused by the impact of the iron ball, because the frame is large enough, so in the case of only 200 iron balls, this change of direction is not much, and it is not obvious, but will Langdon be satisfied with 50 people to dodge 200 balls? Obviously not!

So, in less than 1 minute after the screening began, the screams had become the only sound left in the area, and as time went on, the screams became more and more miserable, and even could be heard by people in Yuanwang City, which was not far from here.

And the people who heard these screams were not close and had doubts.

Didn't they go out to screen the soldiers? Listening to this voice, where is the screening? It's clear that they are being abused!
