The white dust mist with a thick pungent smell of gunpowder enveloped the battlefield of blood and fire. With every roar, there would be patches of Mongolian foot soldiers tumbling in wailing, and pieces of human flesh would shoot out in all directions.

Jia seems to say that this thunderbolt is actually a super-large grenade, although they are all grenades, but the power of the thunderbolt may not be as powerful as the fist-sized grenade in later generations, but fortunately, the grenade is large enough, filled with a full amount of simple black powder, plus iron nails, thistles, iron beads and other messy things, the damage caused is also extremely considerable.

What's more important is that this super-large grenade, in this era when firearms have just appeared and cold weapons are still king, for the first time really shows its cold and terrifying lethality, and the movement is also large enough.

Now, even a fool knows that the continuous earth-shattering noises of the Dao can kill people.

On the three walls under the city of Xiangyang, hundreds of thousands of Mongolian siege soldiers had just been aroused by the earth-shattering morale of the mouth and the warmth of the city.

From the moment they put on that armor, they knew that one day they would die in battle. But if it was a face-to-face death on the battlefield of real swords and guns, it was better to say, in the face of the unknown way of death after the explosion, the comrades around them screamed miserably and rolled over as if they were dead, but they were afraid from the bottom of their hearts.

The unknown is the most terrifying.

The Mongol army's tide of offensive was instantly stagnant, and countless soldiers were scurrying around like headless flies, if it weren't for the large number of archers behind the formation, if it wasn't for the huge siege tower cart blocking the way, if it wasn't for the fact that there were tens of thousands of cavalry of the clan of the kings looking down on the road farther behind, these Mongolian foot soldiers who were besieging the city ...... No, these people are not Mongols, they can only be regarded as servants of the Mongols, and they already have a retreat in their hearts.

A long period of power may be able to suppress them for a while, but when this fear accumulates to a certain level, it is the arrival of their total rout.

On the high platform, the mouth temperature did not take place, and he had already found out that something was wrong and stood up as early as the first explosion.

He didn't have a telescope, so naturally he couldn't see the thunderbolts thrown out of the city, but he was also not one of those illiterate soldiers, naively thinking that it was a punishment from heaven. What's more, the rich white smoke produced after the explosion of the thunderbolt can be clearly seen, not to mention that now the sky above the heads of the Mongolian infantry soldiers under the entire Xiangyang City is shrouded in the white smoke produced by the explosion of the rudimentary black gunpowder, and everyone knows that there is something wrong with the Dao.

Although there is no sign of retreat from the siege infantry so far, it is very clear that if it continues like this, it will be a matter of time before it retreats.

Was that a firearm of the Song people? Why haven't I seen Meng Heng use it before?

"Order, all cavalry moves forward, if there are those who cower and do not retreat, behead!"

At this time, it is very clear that once the momentum of the siege is really defeated, then even if the attack can be continued in the future, it will be difficult to take Xiangyang City in one go.

After all, an army without morale is not much different from sheep.

Soon, the retreating Mongol cavalry began to drive their horses, and even pressed away behind the siege towers.

On the upper floor of the south city of Xiangyang City.

The white smoke had already enveloped the entire battlefield, and Jia Rudao and the others seemed to be in the clouds, of course, if there was no pungent smell of gunpowder.

For the first time, Meng Hui knew that he had always thought that the firearm that could only be used to make fireworks could produce such a powerful and powerful firearm. That small projectile goes down, and the damage produced is not much different from the damage caused by a battalion of archers, you must know that there are as many as 500 archers in a battalion.

As for the crossbows such as the Divine Arm Bow placed on the head of the city, not to mention it. First of all, in terms of rate of fire, the two sides are not at the same level, and there is no comparison between lethality and injury.

Looking at Jia Yidao, who was always looking at Jia Nidao who was wailing all over the place with an indifferent face on his face, Meng Heng found that he knew another layer of this young man who had forgotten his old friend.

The killing of robbers in front of Jiafu had already shown him the tenacity of this young man's heart. In this situation, as any scholar, I am afraid that it is extremely difficult to stand still, let alone be as indifferent as Jia Yidao.

The city is full of stubbornness, the battlefield of flesh and blood, and Jia Nidao, who stands tall like a mountain in a cyan Confucian shirt, is majestically independent. Meng Hui also had to sigh in his heart, the future life was terrifying.

"It's still too powerful!"

Jia Yidao's muttering made Meng Hui shake all over, and he couldn't help but widen his eyes and look at Jia Yidao with a frightened expression.

Grandma is a bear, isn't that powerful enough? How powerful would it be?

"Meng Shuai, although the thunderbolt is powerful, but the siege tower car is really not easy to hit, I wonder if there are preparations in the city to deal with the siege tower car?" Jia Rudao looked at the more than twenty behemoths that were getting closer and closer, and frowned slightly.

It's not impossible for a catapult to hit a siege tower car, the target of the siege tower is big enough, but with the level of those foot soldiers who are now operating the catapult, it still depends on luck to hit this big enough thing.

More importantly, once the catapults were mobilized to fight the siege towers, it would inevitably not be possible to ensure that there would be enough catapults to suppress and deter the Mongol infantry from the city, and the pressure on the walls would be very great.

There are less than 100,000 soldiers in Xiangyang City intact, and the tens of thousands of wounded soldiers can barely go to the battlefield, but they can only be sent to death. Jia Rudao didn't want these battered soldiers to lose too much.

I don't know where Lu Dao Sun Lao, Yang Lao and others have gone in developing cannons now, if there is a cannon, even if it is a small iron cannon with a range of only one or two miles, why are they afraid that the mouth will not spend more than 300,000 troops?

It seems that it is time to write another letter to Yu Ci, asking him to raise the level of assistance to those craftsmen in the Ordnance Prison and get the artillery out earlier. With artillery, why fear the million-strong Mongol army?

Jia Rudao had secretly made up his mind in his heart, no matter what, he must make the artillery as soon as possible.

"Siege equipment such as siege tower carts are rarely used, and the Mongols have never used them before, so ...... Isn't it okay to use thunderbolts? Like? With the power of thunderbolts, it is not difficult to destroy these wooden tower cars. ”

Meng Hui was a little puzzled, how could a guy as big as a siege tower car not be able to hit? A single bolt might be enough to make the siege tower a useless thing in an instant.

Jia Yidao naturally couldn't tell Meng Heng, he just didn't want the Mongolian soldiers to get close to the city wall and cause too much damage to the Hundred Battles Song army who were already in his bag who were defending the city.

As the twenty or so huge siege tower carts got closer and closer, the rumbling sound even overpowered the roar of the endless thunderbolts.

These things are the biggest danger in Xiangyang City!

With a hundred thoughts in his heart, Jia Rudao had already made a decision.
