There are eight of these small cars, which is not much different from the type of wheelbarrow used by farmers in front of the fields. They are just tied to the bottom and left and right sides of the small car.

This kind of unicycle is extremely convenient to use and is most suitable for use on narrow roads. Even if it is a field or a rugged mountain road, it can be like walking on flat ground. Therefore, as long as it is a place where a single person can pass, these unicycle can pass through.

Moreover, although these unicycle are not large in size, their load capacity is also very amazing. They can easily load five or six hundred kilograms. Therefore, on rugged mountain roads, using a unicycle to transport grain is much more efficient than carrying a horse.

It was obvious that these small cars were not used to carry heavy objects. The Wei army quickly transported the small cars to the front. Xu Lin ordered eight single-wheeled small cars to line up in two rows, so that the Wei soldiers who were pushing the cart would walk slowly.

This action made the cavalry deeply feel inexplicable. Logically speaking, there was a horse-piercing nail in front of him, so the Wei army needed to dismount and pick up these horse-piercing nails before they could get on the horse and chase after it was cleaned up.

Xu Lin did not send anyone to pick up these horse-drawn nails, but instead sent several wheelbarrows, which naturally made the cavalry feel incredible. Could it be that these horse-drawn nails would jump to the wheelbarrow by themselves?

The cavalry all widened their curious eyes, wanting to see what the wonderful uses of these wheelbarrows were.

A magical scene happened indeed. As the wheelbarrow advanced forward, the horse-stapled nails hidden in the grass and thorns would fly out automatically, sticking tightly to the black stones under or on the side of the wheelbarrow. The adsorption force was very strong, and with a bang, many horse-stapled nails were sucked up, gathering more and more, and one of them had not fallen.

The cavalry was stunned. He actually had such a magical operation! It was really incredible.

Although the wheelbarrow is moving slowly, its ability to absorb horse nails is really powerful. As long as the wheelbarrow passes through, these hidden deep horse nails that cannot be seen with the naked eye will not hide, and they will all fly out of the grass automatically.

The four unicycles basically fill the entire mountain road, and they run side by side, so no matter how many unicycles are hidden on the mountain road, they will be cleaned up by these unicycles, and basically there are few missing.

Even if there is any omission, I am not afraid. Behind the four cars in front, there are four identical wheelbarrows arranged in the wrong way with the four cars in front, which is specially designed to make up for the missing items. After two sweeps, the horse-stapleds that were not sucked up were basically completely cleaned up.

Although Xu Lin used these unicycle sucking trucks for the first time, he was not surprised. After all, when these unicycles were sent to various battalions, Xu Lin personally tried them. Not to mention absorbing a small horse-drawing nail, even larger knives and swords could be firmly sucked, and it would take a lot of effort to pull them off.

The black stones tied to the bottom and sides of the wheelbarrow are not ordinary stones, but magnets that specifically absorb iron. The Wei army first entered the camp and used them on the battlefield many times. However, this magnet wheelbarrow that specializes in tackling horses was the latest developed by the Wei army to put them on the battlefield.

It is said that this magnet wheelbarrow was invented by His Majesty Cao Liang himself, which made Xu Lin secretly admire him. When he used it, he also felt more respect.

Although this was the debut of the magnet wheelbarrow, the effect was still great. Wherever it passed, all the horse-stabbing nails were absorbed, and there was almost no trace of it. The cavalry followed the wheelbarrow and never stepped on the horse-stabbing nails again.

Although the speed of cleaning the horse-stapled nails by a wheelbarrow is not too fast, it is not too fast than searching by human means. If you search by human means, you have to carefully dig open the grass and thorns inch by inch, or put on long wooden shoes and deliberately trampling them to let the horse-stapled nails penetrate the wooden planks.

No matter which method is, the efficiency is destined not to be too high. After all, the purpose of the Shu army's launch of the Madding was to delay the pursuit of the Wei army and create time for the Shu army to escape. As long as the Wei army was a little slower when cleaning the Madding, the Shu army had already achieved its goal and fled.

Therefore, if you want to crack the horse nail, the only way is to increase the speed of cleaning. No matter how many horse nails the Shu army deployed, the Wei army could clean up the ground as soon as possible, so as not to give the Shu army a chance to escape.

It can be said that this magnet wheelbarrow is really a magical tool to clean up the horse nail. As long as the wheelbarrow passes by, the nearby horse nail will fly out by itself and firmly absorb it on the wheelbarrow.

After the wheelbarrow advanced for a distance, the bottom and sides of the car were densely covered with horse nails. You need to stop and clean up these horse nails before you can continue moving forward.

Looking at the piles of horse-drawn nails, the Wei army soldiers couldn't help but secretly say that they were indeed one thing to surrender. This magnet wheelbarrow is really the nemesis of the horse-drawn nail. With this magnet wheelbarrow, why is the Wei army afraid of the horse-drawn nails of the Shu army? No matter how many horse-drawn nails the Shu army threw, the Wei army can accept them all.

The Shu army, who were throwing horses in front, became more and more frightened as they looked at it. Although they threw it quickly, the speed of the Wei army cleaning was really amazing. They were simply lingering and chasing the Shu army to death. The Shu army had already thrown a lot of horses in the air, and still could not stop the Wei army's advance.

Seeing that there were fewer and fewer horse nails in their hands, the cleaning speed of the Wei army did not slow down at all. What should we do?

蜀兵们立刻禀报给了姜维,姜维此刻正在队伍的中军位置,并不在后队,所以对身后魏军的情况并不太了解,按理说只要蜀军沿路抛洒一些扎马钉,魏军必然需要花费比较长的时间去清理,等他们清理完毕之后,蜀军早就影都没有了.

But unexpectedly, the Wei army found a way to deal with the horse-drawn this time, and actually used a common wheelbarrow to suck out the horse-drawn that fell to the ground. This was what the Shu soldiers in the back team saw with their own eyes. The horse-drawn that were originally thrown into the grass actually flew up and flew onto the wheelbarrow when the wheelbarrow passed by.

If it weren't for the daytime, those Shu soldiers would have thought they had met a ghost.
