"Four or five meters long?"

In the main hall, Xiao Ming paced back and forth.

"No mistake, and the muzzle is very thick. Your highness, the officer thought, this gun must be used to attack the city." Wang Xuan said.

"If it's like what you said, it's really for siege." Xiao Ming's brows are locked.

The urban artillery is a famous siege cannon in history. The Ottoman Empire used this kind of artillery to blow open the wall of Constantinople, but this kind of artillery is very bulky, and it is made by splicing.

In wartime, it needs to be transported one by one and assembled in the battlefield.

However, it's hard to forge such a laborious thing. Moreover, ulban's is a technological product of the mid-15th century. Although it is powerful, its range is also very short.

He did not believe that the barbarians would use this kind of gun as the main gun. After all, Beishan had seen the range of Qingzhou gun on the grassland.

"Only when I sneaked into the test firing range, I saw other traces of shells on the ground. I suspected that there was more than one kind of artillery, so I planned to continue to lurk. Unexpectedly, I was torn down at this time and had to escape." Wang Xuan said.

Wang Xuan said that. He nodded, which was in line with the characteristics of barbarians. He didn't believe that Bei Shan had made something similar to Huihui gun like last time.

It must be reserved for the final siege.

Wang Xuan talked about being betrayed many times. He couldn't help asking, "who betrayed you?"

"It's also a caravan of the state of Dayu, but this caravan comes from Zhaodi. It seems that they are also spying on the cannons of the barbarians. We were discovered by them." Wang Xuan said.

"Zhao di? It seems that it's the person of King Zhao. It's hard for you. Since last time he asked Zhao Yuanliang to go back, King Zhao has always hated him. At this time, it's also the style of King Zhao to put you together. If you show your teeth, you'll be punished. Who doesn't know him? "

"It's just that it's delayed our further exploration of the barbarian artillery." Wang Xuan is not happy.

"No matter, the king has already made a fuss. Since the wuerban artillery appeared, the barbarian's artillery technology is no better." Xiao Ming said confidently.

First of all, through the color, it shows that the barbarians cast bronze cannons, which shows that the barbarians did not master the technology of iron cannons.

In this way, the barbarians had to spend a lot of money on casting artillery, which was a matter of throwing money into it.

Because of the quality of steel and iron mold casting, his artillery can not only be produced in large quantities, but also be of high quality and low price. After all, iron is cheaper than copper, otherwise copper would not be used as ancient currency, just because of the lack of copper.

Wang Xuan nodded, "it's just that the people of King Zhao almost killed him this time, your highness. I can't swallow this tone."

"Hum, since the king of Zhao doesn't give him face, he doesn't have to give him face either. Li San has found out a lot of the whereabouts of Zhao Di's works during this period of time. I'll give them to you and kill them all." Xiao Ming's voice was cold.

Wang Xuan sneered darkly, "Your Highness, it seems that the king of Zhao is going to go crazy for the gun business. Now he sends people everywhere to spy on the gun technology."

"That's natural. The king of Zhao has great ambition. He always wanted to replace the Xiao family. Now when Qingzhou artillery comes out and the imperial army is equipped with artillery, the king of Zhao has to weigh whether his Xuanjia cavalry can capture Chang'an." Xiao Ming said.

"With the lessons of the barbarians in Cangzhou, the king of Zhao was naturally worried." Wang Xuan said with a smile, "however, your highness, although we were exposed in the barbarians this time, the lower officials didn't make them feel better. They also broke down their identities. The barbarians chased them when they chased us. Now the king of Zhao not only cut off the detailed work of Qingzhou, but also cut off the detailed work of the barbarians. In this way, he can only buy artillery from Qingzhou. At that time, his highness should not be merciful."

Xiao Ming can imagine Wang Xuan's danger at that time. Fortunately, the barbarians were different from the state of Dayu. They didn't like to live in the city surrounded by the city wall, otherwise Wang Xuan would not escape.

Squinting, since Zhao Yuanliang left last time, the gun business has been broken.

In addition to the imperial court, only the king of Wei, the king of Chu, the king of Liang, and the king of Yong sent people to contact him. At the same time, they also placed orders. The military workshop was producing export-oriented artillery for them.

And these orders also brought him huge profits. That's why he made so much money in Qingzhou.

"Hum, if he is not benevolent, don't blame me for being unjust." Xiao Ming said hatefully.

This time, Wang Xuan's injury revealed his identity, which will bring a lot of inconvenience to the information collection on the grassland in the future.

King Zhao made it clear that he was trying to make Xiao Mingcheng blind. At that time, he was caught off guard by the barbarians.

In his plan, it is estimated that the barbarians still hope to win the south of Cangzhou City, so that the two pillars of the royal family will fall.

At that time, the king of Zhao would be able to start from the ground.

When he asked Wang Xuan to take a rest, Xiao Ming frowned. After such a long time, it was finally confirmed that the barbarians were forging artillery.

In this way, I'm afraid the decisive battle between him and Bei Shan in Youzhou is not far away.In the last battle of Cangzhou, Bei Shan was humiliated in Shengdu. This time, he will surely come with a large army to recover his lost reputation.

And this time the revenge must be fierce.

But Xiao Ming is also waiting for this opportunity. The array of flint guns will give him the ability to fight with barbarians in the field.

In this way, he and Zhan Xingchang's fortress promotion plan can continue to be implemented, so that he can nibble at the land of Youzhou step by step, until he drives the barbarians out of Youzhou and takes back the former sixteen states of Yanyun.

Thinking of this, Xiao Ming clenched his fist. During this period of time, he had to grasp the production of suifa gun. After suifa gun came out, he had to train for at least three months, which was a long process.

However, this is also a long process for bessin.

Sheng Du, in a silver tent, Bei Shan closed his eyes slightly.

In front of him was an ottoman with curly hair, brown eyes and a high nose.

"Are you sure the urban cannons can smash the walls of Cangzhou?" Said bessin coldly.

"Beishantaiji, please believe me, wuerban artillery once opened the strongest wall, and the wall of Dayu was even more vulnerable." The Osman craftsman looked at beshan in awe.

He was plundered when the barbarians captured the city, where they were forging guns.

Bei Shan nodded. A few days ago, there was a detailed work from the state of Dayu in Shengdu, which was enough to show that Dayu was also afraid of artillery.

"I hope you're right, or I'll cut off your head." Said besan harshly.

Hearing this, the craftsman trembled. Just then, a bodyguard came in and said, "Taiji, the messenger of Korea is here."
