Seeing the scene after the test, all the officials were amazed.

"It's not just incredible, it's simply a miracle!"

"What is this called...the cement wall is so awesome!"

"What kind of brain does Luo Zhang have? How could he come up with such a thing?"

"No wonder he is so confident, he probably knows the result early in the morning!"

"That's inevitable, otherwise he wouldn't dare to come here for the test, and we would be fooled by him!"

Li Shimin looked at the intact wall in front of him, raised his eyebrows, and had a smile on his lips.

He knew that Luo Zhang would not act without aim, let alone let him down.

Sure enough, the results of this experiment made him very satisfied.

But this is not the end yet. When everyone thought it was over, Luo Zhang said again: "Let's try the last thing again, bombard it with artillery!"

Hearing Luo Zhang's words, many people were stunned. Artillery? Boom?

Is there something wrong with Luo Zhang's brain? Everyone knows the power of artillery. No matter how strong the city wall is, it cannot withstand his bombardment.

I didn’t look at the city wall of Liaodong County, but half of it was destroyed by artillery fire in just a few rounds. If not, how could it be so easy to capture Gaoguli’s Liaodong County?

Li Shimin thought it was over, but Luo Zhang actually came again, and he couldn't understand Luo Zhang.

Is it possible that this city wall can really withstand artillery bombardment?

Impossible, how is this possible.

At the first moment, the reaction of everyone and Li Shimin was that it was impossible.

When a cannon was pushed up effortlessly, everyone realized that Luo Zhang was not joking, he was serious.

"Everyone, cover your ears, I'm afraid it will be noisy for a while!" Luo Zhang glanced at everyone and said with a smile.

Some relatively low-level civil servants followed Luo Zhang's advice and covered their ears.

As for the military attaches, they were so carefree that they didn't even cover their heads. They had long been accustomed to hearing the sound of artillery, and now the artillery has been slowly distributed to each military camp.

Even the Qianniu Guards have begun to be equipped with artillery. Although there are not many, they have a few. Whether it is defense or launching a small-scale attack, the artillery can come in handy, greatly improving the overall strength of each military camp.

As for the wooden knots, they have long been the standard equipment of the Tang Dynasty soldiers. Basically, each person can be equipped with two wooden knots. As for direct descendants such as the left and right military guards, each person is equipped with five wooden knots.

This was also due to the increase in production in Yushan's arsenal. At this time, except for Luo Zhang's land, many caves had been dug in Yushan, and a large number of people were stationed in them, all of which were engaged in the production of wood knots.

The demand is too great, and production has to be expanded. Otherwise, the previous production will not be able to meet the demand.

These are just digressions. Luo Zhang had already arrived in front of the artillery. The artillery was thirty meters away from the concrete wall. Luo Zhang did not adjust the angle, but chose to shoot flatly.

If the distance is short, there is no problem in flat firing. If the distance is long, the flat firing shells will fall halfway and have no effect.

As Luo Zhang took over the torch, everyone held their breath and stared at the artillery and Luo Zhang.

When a gunshot was fired, a burst of smoke also spread.

A loud bang was heard as the shell came into close contact with the concrete wall.

Without any delay, the ministers quickly ran towards the concrete wall, wanting to see it clearly for the first time.

Everyone was shocked to see that the cement wall did not fall down. As they looked closer, they saw the shells falling to the ground.

The cement wall in front of me was not intact this time, but had a small crack. However, this small crack did not affect the overall cement wall.

After some calculations, if you want to blast through this concrete wall, you will have to fire at least a dozen rounds in a row.

This made everyone's expressions change slightly. You must know that this is a city wall one foot thick. If it is three feet thick, wouldn't it mean that even if the artillery is damaged, it may not be able to blow through the city wall.

You must know that artillery cannot bombard continuously. If the artillery bombards continuously, the temperature of the artillery will be too high and it will be easily damaged. Generally, it has to stop and cool down after bombarding for a while.

A question lingered in everyone's mind, and they looked at Luo Zhang in confusion.

Now that you have created artillery and built such a strong city wall, what is the use of artillery?
