Chapter 926: Another disturbance

When Coach Arong arrived at Shou'an City, the sun was already shining high, and in the blue sky, strands of light clouds as thin as cicada wings were wandering freely and comfortably.

Different from other cities on the border, the walls of Shou'an City are exceptionally tall, and the city gates are densely covered with sharp maces? !

Coach Arong used a monocular to see clearly the giant thorns that looked like maces, and almost cursed.

Holding back a bellyful of curses and continuing to look at it, Commander A Rong turned the telescope and pulled the city wall closer. Only then did he realize that he had just seen it right: three feet down from the top of the city wall, it was covered with a copper and iron skin of unknown thickness!

"Are the people in this city sick?!" Commander A Rong looked into the distance in surprise, unable to believe his eyes.

He led his troops to fight in all directions, and he had never seen such a city wall, oh, let alone such a city gate!

Whose copper and iron mines are you robbing?

"Your Majesty, from what I've seen, this slave must be guarding against us!"

With a bald mouth, Commander A Rong spoke out his slanderous words. Immediately, a nearby servant came over to answer.

"Is this king's brain just a show-off? I need you to tell me!" Coach A Rong felt a little unhappy. He whipped him and roared angrily, "You think this kind of little trick can make it difficult for me to catch this king?!"

Iron-cased fire mines are quite similar to modern hand grenades. They were made by the Imperial Iron Bureau based on earlier iron-cased mines.

"Come here, hurry up and ask for the military advisor! I will crush this Shou'an City before lunch!"

"How did we get it?!" Anyu, who finally looked at Rufa, couldn't help but exclaimed.

Looking at the entire basket of ammunition, Qi Rong looked extremely ugly: "Then the formula drawing must have been leaked!"

A sharp weapon like that should be classified as the lowest level of confidentiality. Not only is it known to the local people, it is also known to everyone in the cabinet.

It is said that the prototype of the fire thunder appeared as early as the Xiaoyan period. Because the proportions of saltpeter, sulfur, charcoal and other ingredients used in the gunpowder were exactly right, the performance of the fire thunder was very stable. When used, it occasionally killed two enemies and injured two others. It is very practical, so it has been used in actual combat.

"Sister Yuan, you look at the scene and it seems like a pair! Look, there are no siege beams or trebuchets. How will Sheng Yuan attack the city? We are full and ready, so come and give us our heads!"

Anyu had already guessed the opponent's means of attacking the city, and Gu Shide said less and hurriedly ordered Dayao and others to pass on the message: "On one hand, he informed General Chai and Commander Cen of this gaffe, and on the other hand, he ordered all the students who were hiding from the government to do something bad." Prepare to evacuate."

Anyu adjusted the focus of the monocular before pulling the chariot closer. You heard A Rong take a deep breath: "Sister Yuan!"

"Sister Yuan! Sister Yuan! Look!" Anyu had been wandering between General Chai and Commander Cen before. Now he hurriedly came to look for Shengyuan. He opened his mouth and asked Anyu to use a telescope to take a look.

With a solemn look on his eyebrows, A Rong pointed to the back and said, "Look, this coach-looking Shengyuan man is following behind this chariot filled with bamboo baskets!"

It was not until the year after that, when the Ordnance Bureau was adjusting and perfecting the iron gun gun weapon that it accidentally discovered the ingredient ratio that made the mine more stable, so it was ready to continue to refine the formula of the annealed mine.

From then on, until last year, there was no result.

…

"If I had known, we would have stripped out all the copper and iron outside the city and stuck it under the city wall!" A Rong patted the built city wall and murmured to himself, "I also knew that the city wall could withstand grenade bombing."

My voice was slightly trembling, and I quickly shook Anyu's shoulder with one hand: "This is the iron shell fire thunder that the imperial court developed last year!"
