A black ball of gunpowder, a pitch-black metal ball, was stuffed into the barrel of the cannon one after the other.

A handful of straw, which was used as a fire-starting thing, was stuffed into the hole behind the barrel, and the torch was handed to Xu Huabiao's hand.

"Cover your ears with your hands and open your mouth slightly." Xu Huabiao looked at the people behind him.

"Yes, my lord."

Although I don't know why, I was very obedient, and the people next to me firmly covered their ears with their hands, and their mouths opened a little.

Xu Huabiao didn't say much, lit the long straw with the torch in his hand, and then immediately took a few steps back to the side, the same, covered his ears and opened his mouth.

The dried straw burned quickly, and almost instantly, the flames burned down the straw into the barrel.

And then.

Boom.

It seemed that the whole earth shook with the barrel of the cannon.

Xu Huabiao, who was tied to a tree in the distance, and their war horses also seemed to be frightened, and they neighed one after another.

And in the eyes of everyone, a flash of fire shot out from the barrel of the cannon, heading towards Tongguan Pass City in the distance.

Rumble.

smashed on the Guancheng of Tongguan.

The entire tower, like a papier-mâché, collapsed directly.

The whole world seemed to be quiet for a few seconds.

Then, from the bottom of the mountain, the cheers of Xu Huabiao's army came.

It's just that......

"It's high." Xu Huabiao touched his chin, "It can't be that I miscalculated, right?" ”

“…… Lord, this ...... What is it!! Pei Zhuhyun didn't notice Xu Huabiao's self-talk next to him, but his face was shocked.

Of course, the other guards didn't necessarily have much better expressions than her.

All of them were pale.

"Here, readjust and fire a second shot." Xu Huabiao looked at the people behind him.

Whether the cannon is not precise enough, or you miscalculated, there is no shame in doing it again.

Anyway, no one here understands it except him.

“…… Yes, my lord. Lin Zhenna nodded indifferently.

Ten minutes of time.

Xu Huabiao's army under the mountain was clamoring, and Tongguan was in chaos.

Xu Huabiao on the mountain adjusted the mound of soil that had just been built.

After finishing up, the angle of the cannon barrel was slightly lowered, and then Xu Huabiao commanded everyone to use snow to cool down the cannon barrel.

Finally.

"Lord, the pipe is no longer so hot, and according to what you said, wipe the inside of the pipe with a cloth."

Li Jiaen said to Xu Huabiao.

"Has the temperature really come down? It's okay to delay a little bit, it's still going to be long tonight anyway...... But this thing is a treasure that Zheng Caiyan has been making for nearly a year, and if it is broken, she is afraid that she will not find me desperately. Xu Huabiao was not in a hurry, sitting on the ground on the side, holding the paper that had just been calculated, updating something.

"Don't worry, my lord, it's completely cool." Bae Joo-hyun also interjected, "You can use it again." ”

"Well, okay, let's do it again!" Xu Huabiao jumped up from the ground, patted his buttocks, took the torch, and walked to the prepared cannon.

This time, Bae Joo-hyun and the others were all more well-behaved, covering their ears and opening their mouths.

Bang.

Another shot.

And this time......

"Damn...... It seems to be too low again. Xu Huabiao muttered again, "Sure enough, the processing accuracy is not good!" And the power is also used to beat wood, it seems that this thing is also used to scare people. ”

It's just that Xu Huabiao said low, but for the soldiers who lined up in front of Guancheng, this is just right.

Because of this cannon, it hit the gate of Tongguan.

Not only the city gates, but even the stones that were blocked behind the city gates to seal the city gates to prevent rushing cars from hitting the gates were blasted open.

The power is actually not as low as Xu Huabiao said, it's just ...... It's really not that high.

So, in Xian Enjing, "Brothers, rush with me!!" At the sound of the call, the soldiers rushed towards the city gate like a tide.

……

"Where's Kim so-hyun?"

An hour later, in Tongguan, which had been completely controlled by Xu Huabiao's army, Xu Huabiao sat on the upper seat and asked Xian Enjing, who reported to him.

"My lord, Kim so-hyun was killed when you first showed your might." Xian Enjing said.

"Kill??"

"Yes, we were in battle under the gate, and he went to the city to see the situation, and the result was ...... Died directly in the ruins of the city, with no bones left. ”

“…… What a pity! Xu Huabiao sighed softly.

"It's a pity?"

"Oh, I mean it's a pity to shut down the city. Lord Li Xiuman wants to rebuild Guancheng, and I am afraid that it will cost a lot more. Xu Huabiao looked at Zheng Xiuyan and said.

“……”

Jung so-yeon decided to remain silent.

Just now she was taken away from Xu Huabiao's camp by Xian Enjing, and she originally thought that it was just that Pei Zhuhyun wanted to tell Xu Huabiao something related to Luoyang, and it was inconvenient for her to know.

I didn't expect it!

But after more than a quarter of an hour, Xian Enjing was ordered to prepare the whole army to attack Tongguan, and she still felt that Xu Huabiao was messing around and wanted to stop him.

As a result, I didn't see Xu Huabiao at all.

Not only did she not see Xu Huabiao, but she was also directly invited to the rear army by Lin Yuner in the name of "protection" and taken care of her.

Then, there were two earth-shattering bangs.

Afterwards......

Tongguan was defeated.

This...... What kind of operation is it!!

She suddenly remembered the old story of Xu Huabiao blowing up Moling City with divine thunder in Jiangdong.

Xu Huabiao is this person......

Don't talk about the family, it's the Son of Heaven, what can you do with him??

"However, the soldiers in the pass, who fled for a small part, should all go to Chang'an." Park Ji-yeon next to him interjected, "Please make it public, are we sending troops to pursue?" ”

"No need." Xu Huabiao shook his head, "Let them bring the news of the fall of Tongguan back to Chang'an." Otherwise, if Pei Yongjun in Chang'an City can't come out of the turtle shell like Jin Xiuxian, I will induce the divine thunder to bombard Chang'an again? Where do I have so much life! ”

“…… Be. Park Ji-yeon nodded.

The atmosphere is quiet.

"Okay, now that Tongguan has been captured, let's take a good rest." Xu Huabiao looked at everyone and smiled and said, "After a few days of rest, let's set off and continue to Chang'an." ”

"Yes, my lord."

The crowd agreed.

……

"How's it going, have you taken it back?"

When only Xu Huabiao and Bae Zhuhyun were left in the room, Xu Huabiao's speaking style immediately changed.

"Mrs. Yuna said just now that they have all been recycled. It's just that...... It's not spherical anymore, so it shouldn't be able to be used again. ”

"That's okay, take it back to Luoyang and smelt it again, and you can use it again...... In fact, it's just a piece of iron, and it's not a big pity to lose it. The key is that Zheng Xiuyan and ordinary soldiers can't know what just happened. Xu Huabiao's face was serious.

"Don't worry, this lord, it was Mrs. Yun'er who went to take it back personally, and no one knows." Bae Joo-hyun nodded.

"That's good." Xu Huabiao nodded, "Well, it's not too early, you should go and rest early, tomorrow you have to arrange Jenna and their affairs for me, see if you let them go back to Luoyang, or continue to go to Chang'an......"

"Back to Luoyang? They should also be used to fight Chang'an, right? ”

"I don't think so." Xu Huabiao shook his head, "I don't want Zheng Xiuyan to think that I can release the divine thunder casually, otherwise it will be the Son of Heaven or Li Xiuman...... Well. ”

"That's right." Bae Joo-hyun nodded.

"What's more, the cannon is not too easy to use, when I just fired the second cannon, I still felt that the barrel of the cannon seemed to be a little deformed, and if I continue to use it, I am still afraid of exploding!"

"Explode?"

"The problem with black powder...... Well, it doesn't matter, it can't be used now anyway, otherwise it will be dangerous. Xu Huabiao shook his head, "But it's not useless for them to march with them." If necessary, with them and Yun'er, the nine of us will be able to open a gate of Chang'an at night. ”

"Lord, you don't need to take any more risks, do you?"

"What I'm saying is that if it is necessary, I will definitely not go if it is not necessary." Xu Huabiao shook his head with a smile, "This time, Baolan has also built a lot of siege equipment, appropriate, let the soldiers fight a dozen!" ”

"yes!" Hearing Xu Huabiao say this, Pei Zhuhyun immediately nodded.

……
