Zhao Yun from Lin'an City has given up on Xiangyang City, so Jia Sidao and Meng Gong in Xiangyang City naturally don't know about it.

In Xiangyang City, military weapons supervision.

"call!"

Amid the creaking sound of the tall catapult cart, a large ball of black things rose into the air with blue smoke. Seeing that things were about to fall, a sudden "boom!" sound of white smoke rose and flames burst into flames, followed by countless shrill sounds of breaking through the air that made people unable to help but cover their ears.

What can be seen from the naked eye are countless dense black dots that explode from the thing, instantly tearing the dense grass people built randomly below into countless tiny pieces and sprinkling all over the ground.

"Hiss!"

Meng Gong, the military weapon supervisors, and many imperial guards, all of whom were taking a breath when they looked at the results of the things thrown out by the catapult.

What is this? How could it have such great power?

Especially the craftsmen in the military weapon supervision team, these craftsmen are not unfamiliar with all kinds of firearms. The Song Dynasty army had all kinds of firearms, but they were basically not very useful in the two counties' battles.

But the things made by the young powerful today made them feel for the first time that before that, they would not have used them, including the craftsmen of the Song Dynasty.

Looking at the straw man who was torn apart in the city, Jia Sidao muttered, "This gunpowder is still not powerful..." Fortunately, he just muttered, not many people heard it, otherwise the craftsmen, including Meng Gong, would have regarded him as a monster.

This is not powerful? A thunderbolt bomb, all the grass men within a radius of dozens of steps were torn to pieces by the fragmented iron nails and other things filled in the thunderbolt bomb. Their power was far greater than any firearm equipped by the Song Dynasty today.

In fact, before this, the Song Dynasty had already had the fireball. It was also thrown by a catapult, but the fireball was made of multiple layers of paper into a hard spherical shell, filled with gunpowder, poisoning agent, smoke agent and other substances, and then sealed. During combat, before firing each time, the shell of the fireball was burned through with a red-burning cone, and then thrown out with a catapult, so that the fireball burst to kill the enemy.

The principle is basically the same, but Jia Sidao's thunder bullet is obviously much higher than the fireball. It uses a lead made of special nitro cotton thread, filled with caltrops, nails, iron beads and other things to increase lethality.

However, it was precisely because there was a fireball in the army of the Song Dynasty that the craftsmen in Xiangyang City could understand Jia Sidao's intention to make this simple cannon so quickly. If it weren't for wasting some time on the production lead, it would be faster.

Of course, the simple bomb thrown by the trencher is obviously far from the cannon that Jia Sidao wanted. However, under the current circumstances, it is obviously too unrealistic to talk about the cannon, not to mention that in Jia Sidao's view, this thunderbolt bullet is already sufficiently used.

"Hahaha! That's great, Sidao. With this thunderbolt, even if he doesn't give a million soldiers, I can still keep Xiangyang City as stable as Mount Tai." Meng Gong, who came back to his senses, pulled Jia Sidao excitedly and said ecstatically.

Indeed, with this thunderbolt, judging from the scope of this thunderbolt, according to the Mongols' siege, if one is thrown down, you will have to lie down dozens or hundreds of people. One hundred, that is tens of thousands. If you make thousands or tens of thousands, who can capture Xiangyang City with such a huge killing weapon?

"Meng Shuai, Sidao has said a long time ago that Xiangyang City will never be lost. Now, do you believe it?"

Jia Sidao touched the little stubble that grew on his chin and said with a smile.

"Believe! Sidao is sincere and does not deceive me!" Meng Gong patted Jia Sidao's shoulder and said excitedly.

"Then the commander can give orders. Now that the war is about to begin, the commander should immediately order people to organize the people of the whole city to assemble the catapult cart for the military weapon supervisor. The catapult cart is very simple, with a range of more than 600 steps. There must be many carpenters in the city. Lord Wang only needs to send dozens of experts from the military weapon supervisor to supervise the craftsmen. As for the remaining military weapon supervisors, they will do their best to make gunpowder, the lead wires and shells for the thunderbolt bombs. As for Lord Wang, he still needs to continue to test the burning time of the lead wires, especially the production of the lead wires must be accurate, otherwise if the lead wires are burned out in advance, he may hurt himself before it hurts the enemy."

Jia Sidao looked at Meng Gong.

"I am the commander and ordered all the craftsmen in Xiangyang City to go to the camp immediately to collect strong timber. All other things must be followed by Lord Jia's arrangements. Those who violate the order will be killed!"

Jia Sidao had already made all the arrangements he should have made, so Meng Gong naturally enjoyed delegating power.

A group of excited craftsmen hurriedly obeyed the orders.

"Meng Shuai, let me talk." Jia Sidao saw that the most difficult thing had been solved, and the rest was to work overtime to make thunderbolts, and whispered to Meng Gong.

Meng Gong was in high spirits at this moment. The mountain that was pressing on his heart had been moved away. All of this was brought by Jia Sidao, so he naturally would not refuse. With the thunderbolt, Meng Gong naturally no longer worried about defending the city. After all, the power was there, it depends on how many people were sent to the city.

In the military weapon supervision office, Jia Sidao and Meng Gong sat opposite each other.

"Meng Shuai, the 60,000 cavalry that Wen Buhua, who restrained Huaixi and Huaidong war zones, was mobilized to the city of Xiangyang to participate in the siege. This is a god-given opportunity for our Song Dynasty."

As soon as the two of them sat down, Jia Sidao said directly.

Just guarding the city is obviously too cheap and not too hot. Jia Sidao wants more. Whether Mongolia has really changed the main direction of the attack or has a temporary intention, in Jia Sidao's opinion, they must be beaten to hurt so that they can realize that if they want to destroy the Song Dynasty, they must first be prepared to pay enough price.

Only in this way can Ogedei divert his attention and stare at the desolate land in Europe that is still far behind the Song Dynasty.

"Si Dao means to ask Huaixi and Huaidong to send reinforcements to catch turtles in a jar?" Meng Gong, who had been through many battles, immediately understood Jia Sidao's intention and said excitedly.

"That's exactly what it means..."

"Report to the Grand Commander, the imperial edict comes from the capital!"

Before Jia Sidao finished speaking, Meng Gong's personal soldiers shouted at the door.

Meng Gong and Jia Sidao looked at each other, and they couldn't help but think of a question in their hearts. Could it be that the reinforcements in the court had arrived?

"Come on!"

Meng Gong took the secret letter from the Privy Council sent by his personal soldiers. When he saw the seal stamped below, his face was first angry, and then he was helpless to hand it to Jia Sidao.

Just from Meng Gong's expression, Jia Sidao could guess a lot of things. However, since Meng Gong had already handed over the secret letter, Jia Sidao naturally would not refuse. After taking the secret letter, he glanced casually and placed it gently on the desk in front of him.

"Haha, it seems that the court is in chaos. The emperor is even harder than us. What a pity that this great opportunity!"

"...The Emperor did not read it wrong, alas..." Meng Gong looked at Jia Sidao who was still smiling and sighed.

"It's really enough to get the rest of my life, and the three armies came out together, haha."
