"Is this still a human weapon? Isn't this an immortal method? A group of people looked at each other.

Even Lei Hao, who is the best at military affairs, was dumbfounded.

What would happen if such a weapon could actually penetrate iron armor?

As a result, the lethality of this weapon is enough to kill all the current swords, guns, and halberds in an instant. And once the army is formed, it is a typical person who sees who second, who sees who kills.

"A river of blood...... Bleeding! The monk on the side muttered. He was the presiding officer of the Tenryu Temple, and he had never seen anything, but now he was so frightened that his face was bloodless.

What does the appearance of such a weapon mean, even Wang Lu, who does not understand military affairs, understands. "Congratulations, Your Majesty, our Daying Dynasty has another artifact of Zhenguo!"

Zhenguo artifact? Li Hang smiled, he didn't laugh at Wang Lu's shallow knowledge, but laughed at the fact that the word artifact was really worthless.

Pointing to the larger artillery on the side, Li Hang smiled and pointed to the temporary city wall not far away. "Several, this is the temporary section of the city wall built yesterday, it is a by-product of the production when paper is used as a weapon, if you don't believe it, you can go over and have a look, you can also ask the soldiers who defended here yesterday, this wall was just dried last night, the main use is that kind of cement material, now you can go over and see how hard it is!"

Hardness is a sign to check whether the wall is qualified.

At least you can't use a trebuchet to smash it open, that's the last word.

Therefore, many of the walls in these years were made of masonry.

Most of these brick walls are made of fired bricks and large stones, which is why they are hard, which is rare in the world.

Some of the walls have stood for thousands of years thanks to the cheap leather of this material.

Can cement be made?

Li Hang prepared another thing.

This is the trebuchet.

That's the good stuff that the royal family made.

The key components of this trebuchet are made of iron, which can be said to be powerful, and it is effortless to smash some small city walls.

But in the face of such a large thickness of the wall, it is also a little weak.

The reason why Xiongguan, which is rare in the world, is so awesome, because of its actual large thickness and hardness, which makes many siege engines dumbfounded.

Because of this, they have survived for thousands of years, and even in 194X, they could use their residual heat to stop the invading army of the Japanese devils.

It is precisely because of this setting that this situation occurs.

Now the craftsmen of the palace are assembling trebuchets, and now they are aiming for another identical section of the city wall over there.

"At this time, you can go over and see this kind of wall." Li Hang took them over to take a look, while the emperor's personal guards on the other side were also monitoring the movements of the people here.

When this large group of people walked to the edge of the newly built city wall, Emperor Yingwu asked the people on the side to prepare the common things used to build the city wall.

In those days, the tall walls were basically incomprehensible, and it was difficult to destroy them. But if there are gaps in the walls......

Looking at this new city wall, a group of people were speechless and choked, this is too smooth.

Although many city walls can do this, but most of their walls are adobe, those walls built with bluestone and stone bricks, inevitably have some gaps, even if it is filled with rice milk mixed with some other fillers, but as long as you use a knife to insert it, you may be able to find a "road to the wall" for a day, but this will be very dangerous.

After all, some city walls are more than ten meters high, almost three stories high, and some even hit about fifteen meters and four stories high.

If this Nima wants to climb up, I'm afraid that he will have to have special training, or this kind of person is the kind of person who is a master of art and bold.

It is certainly not an easy thing to climb on, and to suffer the blows of those soldiers.

Modern special forces are easy to do, that is because there is no such wall in modern times, and a large wall in ancient times could block most of the enemy.

Unless you are very "ingenious" to dig tunnels from the ground, but ancient times also guarded against this.

This subtle gap between the walls can be seen. "Smash me!"

Emperor Win Wu waved his hand and asked those soldiers to go up with some simple demolition tools.

Even those strong city walls can't withstand such demolition, because these soldiers have steel things in their hands, although it is a waste to smash the city wall, but this can quickly make some seams or some weak links in the city wall visible, of course, this kind of thing can't be played on weekdays, otherwise, do you think those soldiers above are dead?

Picking up the tools, the soldiers began to smash them.

For them, there was no pressure to tear down a section of the wall.

The tools in their hands could easily break through the parts of the mixture of rice milk and the mixture, and they could climb up as long as they could make some footholds.

But when they started to do it, there was a "ding" sound when the tool landed on it.

This is definitely something that has not been done before.

Seeing that they have been working under the ground for a long time, if they follow the habits of those troops in the past, they all want to be powerful.

It can be said that they can easily climb the wall that is not well-made in the earth, and even if it is a high-quality wall, with their ability comparable to that of a professional rock climber, it can basically be done.

"What's going on?" It's no wonder that Emperor Win Wu frowned, this kind of force is basically the most elite force in their hands, and it is not an exaggeration to say that it is a special force.

Wouldn't it be trivial if they did go up and build these walls?

But now?

These soldiers under the city wall were almost out of incense, and they didn't go up.

There's no place to climb.

Inside the city walls, there are some vents or outlets to prevent thermal expansion on the one hand, and a lot of damage caused by water seepage on the other.

But these places that can be climbed are all inside.

So no matter how hard they knock, they have to pry open the cement layer.

Pry open the cement layer...... Hehe, you still have a chisel and a hammer handle, otherwise you will use brute force just by manpower.

The result?

As a result, no matter what they do, they will always end up with one thing, and that is that their violent methods will make a loud noise, and then they will be discovered by the soldiers on the city walls.

"The cement only takes a few days to dry after pouring and paving, creating a rock-hard surface that is a good choice for building walls and paving roads."

But this is not the most important thing, the most important thing is that the weapons of these people could not cause damage to the walls.

That's the worst thing.

This problem of not enough harm is the most troublesome.

"The pavement formed by this cement will not have a problem for decades, and the formation of this kind of city wall can also last for a long time, although it is not as good as the city wall made of bluestone and bricks, but the surface of this city wall can be brushed with cement, to ensure that the surface will not appear that kind of easily appeared cracks to be climbed, it can be said that it is a very good material, if Your Majesty is interested, we can talk in detail, see the hardness of these city walls, let's take a look at these weapons! After all, they're the protagonists! Li Hang said with a smile and looked at the trebuchet that was ready over there.
