After the tiger and leopard rode two rounds of arrows, Dong Zhao ordered it to stop, obviously, he had realized that archery alone would not have any effect. We can only wait to see what further actions the Shu army has, and then take targeted countermeasures.

He is not very worried about this, the so-called fire comes to flood, water comes to the earth, no matter what the trick, there is always a way to crack it. He had not seen this tactic of using a tower shield to form a shield wall and slowly advance slowly, as far as he knew, this tactic was usually that the shield wall slowly advanced in front of the enemy's line, and then another soldier hiding behind the shield wall was responsible for attacking the enemy.

Soldiers hiding behind tower shields are usually pikemen or spearmen, so that they can use their long spears to reach out from the gaps in the tower shield and stab the enemy on the opposite side, and the enemy wants to attack them, but the weapon is blocked by the tower shield.

This tactic is good, it can protect the soldiers well, and they will not be damaged by the enemy's bow and arrow until the two armies meet each other, and even when the two armies are close to each other, your own soldiers can still be protected by the shield wall, which greatly increases the chance of victory.

However, any tactic is not omnipotent, each tactic has its advantages, but also has disadvantages, Dong Zhao, who is familiar with the art of war, naturally knows how to break this kind of tower shield spear formation. Even if it can't be broken, it doesn't matter, just let everyone turn over and retreat.

These tower shields are so bulky, they can't run fast at all, even if they abandon the tower shields to pursue their own side, they don't have to be afraid, the enemy is infantry, it is impossible to catch up with their own cavalry, this battle, they can be said to be invincible.

The shield wall did not stop, braving the rain of arrows until it was about twenty meters away from the tiger and leopard cavalry camp, and at the whistle of an officer, Qi Qi threw the tower shield to the ground, and suddenly, a neat shield wall appeared in front of the people.

There was silence, and the soldiers on both sides waited silently for the shield-bearers to perform. The difference is that the tiger and leopard riders in front of the shield wall are confused, they know that these tower shield soldiers of the Shu army will definitely have follow-up actions, but they don't know anything about what they want to do. The Xianbei cavalry, who was behind the shield wall, saw clearly what the tower shield bearers were doing.

They could see very clearly that there was not just one person behind each tower shield, but two people, except for a strong tower shield hand who was holding the tower shield with his shoulder~ and another person was busy.

The busy soldier took out two short iron rods with the thickness of his arms, and screwed them into the two holes in the top of the tower shield.

The two iron rods were only a foot long, with threads at one end and a deep groove at the other. And those tower shields were obviously specially made, and at the top was a palm-wide and an inch thick piece of iron, which extended downwards on both sides and became an iron sheet.

The outer surface of the shield was covered by an iron sheet on the outside, and because the inner side of the shield did not need to resist the bow and arrow, the iron sheet only extended down about a foot to help fix the large iron block at the top. There are many nails on the inner and outer iron sheets, so that the iron sheets are closely connected to the shield sandwiched in the middle.

The so-called shield is a thick wooden plank, and the iron sheet is nailed to the board with many nails. There are several iron cones that can be folded up at the bottom of the tower shield, the ground is muddy, and these iron cones can be stretched out, and when the tower shield is on the ground, these iron cones are inserted into the ground, firmly grasping ~ the ground, helping the tower shield hand to better resist the impact of the enemy.

The shield body, the big iron nails, and the wheels (bearings) that are also conducive to dragging, plus such a large piece of iron and iron sheets, the weight must not be light, in addition, there is also the weight of the handle, which makes each tower shield weigh dozens of pounds, no wonder each tower shield hand is a big man.

Now these tower shields have walked a distance of hundreds of meters with shields in hand, their faces are not red, and they are not panting, which shows how strong their physical strength is. Their physical fitness is not strong, walking hundreds of meters with a shield is just a pediatric, and withstanding ~ the impact of the enemy is the real test for them.

To get back to the point, there are two holes separated by a certain distance on the iron blocks on the top of these tower shields, and the threads are opened in the holes, and the two iron rods can just be screwed in and fixed. After securing the two iron rods, the soldiers wound and hung their arms around the deep groove at the other end of them.

The function of the deep groove is to prevent the hanging boom from slipping. The boom arm is made of springs and cowhide, and in the middle of the two boom arms is a pocket made of cowhide, and in less than five minutes, a small "Angry Birds" is installed.

It turns out that this is an "Angry Birds" that works with the tower shield, and the soldier who hides behind the shield with the tower shield hand is a bombardier. Since its invention, there have been many variations of Angry Birds, and it has been used in many ways, but this is the first time it has been used with a tower shield.

After the tower shield version of the "Angry Birds" was built, the bombardiers lit a torch and stuck it in their pockets, and then took out black "duck eggs" and put them on their leather pockets. At this point, preparations for the launch have been completed and the Angry Birds are ready to be launched.

These duck-egg-sized objects are the smaller versions of the Thunderbolts, and since the Tower Shield version of the "Angry Birds" has only one person responsible for firing, the power is insufficient to fire too large objects, otherwise the range will be greatly affected.

In order to solve this problem, the only way to solve this problem was to reduce the size and weight of the bombs dropped. As a result, this miniature version of the duck egg-shaped bomb came into being, and the official name of this small bomb is the Thunderbolt Zero, in fact, many people in the military jokingly call it "duck egg". The bomb was small, but it looked like a thunderbolt, and the iron shell was cast into a grid, like a pineapple.

Once it explodes, this one-grid structure will form countless fragments and fly everywhere, although the lethality and killing range are much lower than the authentic thunderbolt, but within three or five meters, there is still a lot of lethality, and it can even be fatal within two or three meters.

In the unified command of the officers, the tower shield version of "Angry Birds" officially appeared on the stage. I saw the bombardier wrap the "duck eggs" in the leather pocket, pull the leather bag back with both hands, retreat to the back, and the whole person fell backwards, using his weight to pull the bullet arm to the extreme.

In fact, the hardest part was the tower shield hand, who had to put their shoulders on the tower shield in order to prevent it from being pulled down, and struggled to keep the tower shield upright. This is the equivalent of the tower shield hand and the grenadier pulling a bowstring together.

The tower shield hand is equivalent to the left hand of the archer, he plays the role of fixing the bow, and the grenadier is equivalent to the right hand of the archer, and he is responsible for pulling the strings. The "duck eggs" that are shot out ~ with the power of two people can be imagined how much power it contains.

I could only hear the sound of "whooshing", and countless "duck eggs" flew into the sky, black and pressing, like a flock of crows, flying straight to the camp of the tiger and leopard. The tower shield hand and the tower shield in their hands all shook for a while, but they quickly recovered, and still straightened the tower shield and stood upright.

It is not the most difficult for them to resist ~ the tower shield, the most difficult thing is that the moment the grenadier lets go of the bullet arm, the tense strength suddenly loses, and it is easy to fall due to the reaction force if you are not careful. They have obviously trained to get to where they are now.
