"Why?" Zhao Heng was puzzled.

"The artillery is powerful, I am afraid it will hurt the people by chance. I hope the emperor can find an empty place."

"Oh?" Zhao Heng became happy when he heard this.

The general said this indirectly proved that the cannon was indeed very powerful.

This time he rejected the envoy of Beidi and was always worried.

Now, he finally felt much more at ease.

Dou Wei and Liang Kai looked at each other with a serious expression.

"Since that's the case, go to Royal Linyuan." Zhao Heng raised his voice octave.

In the afternoon, the Liang family's fleet arrived at the foot of Jinling City.

Upon learning the news, Zhao Heng boarded the Luanyu and headed northeast.

When the two artillery families arrived, the artillery generals of the King of Yan and the artillery generals of the Liang family commanded their respective soldiers to adjust the artillery, and then waited for Zhao Heng's order.

The Sixth Prince was next to the cannon early in the morning, with a proud look on his face.

This is an opportunity to show your face in front of the emperor and the ministers.

"Let's start, who will come first!" Zhao Heng had been itching along the way.

Seeing that he was ready, he immediately ordered.

At this time, the sun shone with no clouds in the sky, and the vision was very clear.

"Let's try the King of Yan's artillery first." Liang Kai's eyes swam back and forth on the King of Yan's artillery and his own artillery, with an awkward look.

But in terms of appearance, the Liang family's artillery lost to the Yan King's artillery.

The outer wall of the King of Yan's cannon is smooth and flat, like the mirror surface of a bronze mirror.

However, there are holes like honeycombs on the outer wall of the Liang family's cannon.

The barrel of the Liang family artillery deviates from the center line, while the barrel of the King of Yan artillery is very standardized, just on the central axis.

The most important thing is that even such artillery was a good product selected by the Liang family from a hundred failed products.

If Zhao Xu was here and witnessed the Liang family artillery with his own eyes, he would have sneered.

Because he could tell at a glance that the Liang family must have used clay molded cannons.

This mud mold casting gun has three disadvantages. First, the mud mold has low breathability and is difficult to dry thoroughly. After being baked by charcoal fire, it is often dry outside and wet inside, and moisture is generated during casting. This is the origin of honeycomb holes.

For this reason, mud mold casting cannons often have defective products. In the late Ming Dynasty, the book "SiFrench Divine Machinery", there is even a saying that "if you get one hundred casting, you will be a national player."

Second, after the casting of the cannon is completed, the mud mold needs to be broken and taken out. This is extremely time-consuming and labor-intensive, and it is difficult to standardize the artillery manufacturing.

The third is that when the iron is poured into the mold, the core will often disturb, so that the cast gun chamber is not on the central axis of the gun body.

The Liang family's artillery has three disadvantages.

"Then let's try the King of Yan first." Zhao Heng glanced at the Liang family's artillery in disgust.

Just as people say that ugly and beautiful things are said, he didn't like the Liang family's artillery at first sight.

The artillery general received the order and asked the soldiers to remove gunpowder and shells from the two wooden boxes.

First, use a strip to clean the barrel, and then fill the gunpowder and shells one after another.

Finally, he gave the torch to the Sixth Prince.

"Your Highness, just ignite this lead." The artillery general looked dull.

No one in the royal family wanted to come to Jinling. They only recognized the King of Yan and were unwilling to pay attention to the others of Dasong. He was chosen and could only admit that he was unlucky.

"The cannon is powerful, and it is best for His Highness to cover his ears after ignition." The general reminded him again.

The sixth prince snorted and ignored the general.

He wanted to see how powerful the King of Yan's artillery was.

Taking the torch, he lit the lead.

"Sizi..." The lead burned quickly, and the flame drilled into the small hole in the cannon.

"boom……"

At this moment, a fire broke out with a thunderous explosion.

The sudden loud noise made Zhao Fang sit on the ground.

Excessive fear and fainted.

Zhao Heng and the ministers, standing thirty meters away from the cannon, were also very embarrassed.

Many ministers were trembling, their legs could not support each other, so they could only support each other.

There was even a water stain on the place where the minister stood, which was urine.

"It's so terrifying!"

Zhao Heng grabbed Liang Cheng's arm tightly and tried not to expose his trembling legs under his long gown.

In order not to let his voice tremble, he yelled.

Liang Cheng was very unbearable, his legs were half bent due to weakness.

But he felt the strength of Zhao Heng's hand on his arm, and he held on.

He can be embarrassed, but the emperor cannot be embarrassed.

After Dou Wei, Han Zheng and others' initial fear, their hearts were filled with shock. It took them a while to recover.

Immediately, their eyes looked at the cannon full of desire.

Previously, they were just guessing.

But now that they saw with their own eyes, they finally understood why the Yuan family's 150,000 troops were defeated by the King of Yan.

But this thunderous loud noise would scare the soldiers on the battlefield.

"Congratulations to the Emperor for obtaining this magic weapon!" Dou Wei stepped out his legs and came to Zhao Xu with difficulty, lowering his body deeply.

Han Zheng, Liang Kai, Xie Duan and others reported it and hurriedly followed up to congratulate him.

"Hahaha..." The obedient appearance of the ministers made Zhao Heng feel unprecedentedly happy, just like when the cannon burst out.

The third prince looked at the sixth prince who was still unconscious on the ground.

Originally he thought he would be very happy, but now he can't be happy no matter how hard he is.

Indeed, he made the Sixth Prince look ugly.

But this proves the great power of the King of Yan artillery.

And such a powerful firearm was made by King Yan.

There is no doubt that artillery will become another important bargaining chip for the King of Yan from then on.

After all, his father did not seem to have the intention of asking the King of Yan to hand over the artillery casting method.

And even if his father wants it, will the King of Yan give it?

After all, King Yan has now formed a considerable force.

"All my beloveds are exempted from courtesy." At this time, Zhao Heng's laughter stopped, and now he was completely relieved.

With such a country's important weapon to guard the frontier, what can he do to Da Song?

Now, he no longer regrets the matter of handing over the King of Yan to Beidi.

Otherwise, if the King of Yan destroyed the cannon-making method in anger, it would be a huge loss for Dasong.

Dou Wei noticed Zhao Heng's expression and felt a slump in his heart.

He had never seen Zhao Heng feel so confident.

However, the prince of the King of Yan has artillery, and their clan also has artillery, so the scenery cannot be taken over by the King of Yan.

So he said to Liang Kai: "Shangshu Liang, it's time to try your Liang family's artillery now."

"Start the cannon test." Liang Kai swallowed and yelled at the Liang generals.

In terms of appearance, Liang's artillery has lost.

Now he hopes to beat the Yan King's artillery in range.

Zhao Heng also wanted to see the Liang family's artillery, so he sat down and watched again.

"Boom!" Another cannon sounded.

However, the cannon is obviously not as clear as the cannon of King Yan.

As the smoke dissipated, Zhao Xu glanced at the ministers, "You are here to find where the shells have flew away? See whose cannons flew far away."

After saying that, he went straight forward and ordered the imperial guards to ride horses in the forest garden.

When the sunset has a little red left, it will sink into the skyline.
