Originally, the soldiers thought that cleaning was not a difficult thing, but after they really did it, they sent it, and it didn't seem to be so simple! It has been going on for more than an hour, and it seems that it has not yet reached the standard set by Sun Ce before. What to do? What else can I do? Only keep up the good work!

As for Sun Ce, now he has asked Chai Meng to find a group of farmers who are working, digging and planing in an open space in the school field, and he doesn't know what Sun Ce wants to do.

Soon, according to Sun Ce's design, five piles, wide trenches, low slabs, high benches, high and low platforms, ladders, single-plank bridges, high slab walls, and barbed wire (barbed wire is not yet available, Sun Ce can only ask the carpenter to make a wooden grid, which is regarded as barbed wire). The most common 400-meter obstacle in the military camp in later generations was laid out!

Seeing so many working people, the corners of Sun Ce's mouth rose slightly, and he nodded, this is exactly what he wanted: "Chai Meng, you must remember that today's salary cannot be less, everyone is, you personally supervise!" ”

"Yes!" Chai Meng nodded, and then asked with some confusion, "Lord, what exactly do you want to do?" How...... Why does it look a little awkward! ”

"It's a runway!" Sun Ce smiled slightly.

"What? Runway? Chai Meng was dumbfounded, he never thought this was a runway! Lord, this is the runway? ”

Looking at Chai Meng's surprised appearance, Sun Ce secretly laughed in his heart, it was normal for ancient people not to recognize this thing, even in the later life, if an ordinary person was brought here, I am afraid he would not be able to recognize anything, right?

"Yes, it's a runway!" Sun Ce nodded and explained, "Here I name it Wulian Piles, here it is called the wide trench, this is the low slab, this is the high bench, the high and low platform, the ladder, the single-plank bridge, and this high slab wall, and the wooden fence net. From here, we soldiers sprint to the obstacle track in 100 steps, then cross these obstacles in turn, and when we get there, turn back, and after passing the obstacles, sprint back in 100 steps, all this is done, and we need to complete it in a cup of tea! ”

"That's all? A cup of tea? Chai Meng said with some disdain, "I don't need it at all!" ”

"Oh?" Sun Ce raised his eyebrows, although Chai Meng had some force, but for the first time he came into contact with such an obstacle track, Sun Ce didn't think that Chai Meng had the ability to complete it in the time of a cup of tea! Anyone who has ever been a soldier knows how difficult it is to run a 400-meter obstacle course, and there is even a saying in the barracks: "It is better to run 5 kilometers than 400 meters"!

"Why don't you try it when you're done?" Sun Ce asked.

"Just try!" Chai Meng couldn't wait for a long time, he wanted to see what kind of reputation Sun Ce was making.

"Well, if you can finish it in one cup of tea, I'll get a reward!" Sun Ce smiled slightly.

"Good! Deal! Chai Meng didn't pay attention to this runway at all, through Sun Ce's explanation just now, he was full of thought that he would be able to complete it in one cup of tea or even half a cup of tea!

However, it is still very laborious to complete this obstacle course, and it took more than two hours for the people to finish the seemingly simple work!

"Go up and try it? I'll clock you! Sun Ce smiled slightly and pointed to the runway over there.

"Hmm!" Chai Meng nodded, and came to the starting point with confidence.

"Let's go!" Under Sun Ce's order, Chai Meng rushed straight to the obstacle track like an arrow off the string.

Rub and rub......

Chai Meng ran very fast, not a few steps to the first obstacle "five piles" in front of the side, five piles basically not too difficult, very easy, Chai Meng passed, then, Chai Meng shook his head disdainfully, this five piles, what's the use? It's a person who can pass it, right?

In the wide trench of the second level, Chai Meng jumped easily and crossed it directly, without feeling the slightest pressure!

The third level is a low board, not much high, Chai Meng easily jumped over with his hand!

The next high board, also called the Irish wrench, Chai Meng encountered some difficulties, he did not expect to be so high, to the board, he did not cross in time, but grabbed the board with both hands, and then struggled to make the body up, this came to the high board.

"Whew!" Chai Meng let out a long breath, this obstacle running didn't seem to be as simple as he thought!

Some of the projects that followed, such as high and low platforms, such as high slab walls, did not put too much pressure on Chaimeng, but such as ladders, single-plank bridges, and even wooden fence nets, all caused a lot of difficulties to Chaimeng! Moreover, although the route when he came back was the same, the way he passed through the obstacle was different, so this caused a lot of trouble for Chai Meng! Especially the low board when I came back, it turned out to be drilled over! And the hole is so small, how did Sun Ce come up with it?

"Whew! ...... "Chai Meng finally returned to Sun Ce's side. Before and after, Chai Meng spent nearly a stick of incense!

"How? How does it feel? Sun Ce asked with a slight smile.

"I throw in the towel! Admit defeat! Chai Meng didn't think about it, and directly admitted defeat.

The corners of Sun Ce's mouth rose slightly, and later generations used this 400-meter obstacle run to train, mainly because 400 meters was the ultimate range of assault rifles in later generations. Therefore, on the battlefield,. 400 meters is a tipping point for death! In the process of training, soldiers constantly improve their ability to overcome obstacles, they can quickly find shooting bunkers in actual combat, through the different terrain of the battlefield, so as to ensure their own safety, reduce the mortality rate on the battlefield, for mechanized infantry and other special forces, the 400 meters on the charge road can be said to be a critical moment of life and death! It is precisely because of these that the 400-meter obstacle run has become an indispensable event in the military camp in later generations.

And now, for the army trained by Sun Ce, what they have to face is bows and arrows! And the maximum range of today's bows and arrows is only 100 steps, which is equivalent to more than 100 meters in later generations, so Sun Ce temporarily set 200 meters as the critical point of death! He's going to train these soldiers to be able to pass twice the critical distance of death perfectly!

What's more, training in such an obstacle course can also greatly improve the physical fitness of the soldiers!
