When the Huns attacked again, it was a very common sunny day.

After the signal of the siege reached everyone's ears, General Xie immediately organized manpower and prepared to go to the city to supervise the battle.

At this time, Su Hengyu proposed to go to the wall with General Xie and them, saying that he wanted to see with his own eyes how his plan went.

She and Xie Jing and a group of female soldiers didn't know what to do when they went out of the city, and Xie Qingxiao kept hearing people tell him these days that the female soldiers were led out of the city by Xie Jing for a while, but when others asked, they didn't say a word.

Xie Qingxiao was also very curious when he learned about this, and took the initiative to find his daughter and Su Hengyu several times, but both of them looked confidential, and half of the extra words were not leaked, which made Xie Qingxiao curious.

But today, Su Hengyu proposed to go up to the city tower to check the effect, but Xie Qingxiao naturally refused to agree.

He explained to Su Hengyu: "This is not a trivial matter, there will be stray arrows flying on the city tower, and there is a risk of injury if you are not careful." If we don't hold it, the Huns below will climb the city wall. The ferocity of the Huns, we may not be able to protect you. ”

Su Hengyu said very indifferently: "General Xie doesn't have to worry, if our previous arrangement has worked, then this time the Xiongnu will never be close to the city wall." ”

Not only did she say this, but even Xie Jing followed and persuaded: "Dad, you promise Hengyu, we are not messing around, we know what the results of what we do will be, as long as you follow us to the city wall to see, everything will be understood." ”

Both of them had serious expressions, as if everything was under their control.

Xie Qingxiao still had some scruples in his heart, but he knew what kind of character his daughter was, and she might be willful in other things. But in matters related to the safety of Great Wei and the survival of the soldiers, she would never dare to take the slightest risk, and would not joke about such an important matter.

He said, "Since you are so confident, I will believe you for the time being." Suzhi County needs to put on armor and go up with us with weapons. And you can only stay there for half an hour, and if the fighting is fierce later, you must obey my orders and leave the danger zone immediately. ”

"Okay, just do what General Xie said." Su Hengyu agreed without fear.

She knew very well how powerful the magic weapon she had spent nearly a year to get was powerful, if it weren't for the fact that she could intuitively see this battle that changed the fate of Great Wei, she would not have left the affairs of Nanyi City alone and stayed here for so long.

You must know that in the days that Su Hengyu stayed in Luoyanguan, there were constant letters from Nanyi City, all of which asked her to solve the matter here quickly and go back to work quickly.

But she didn't pay any attention to it, and before she came out, she had already assigned everything at hand.

In the past year, she has unearthed a lot of capable people, and many officials have long grown up to be able to take charge on their own. She didn't believe that if she left for a few days, Nanyi City would be in chaos.

There is no armor suitable for Su Hengyu in the barracks, although she is considered tall and strong among women of the same age, she is still far behind the generals in the army.

Fortunately, Xie Jing also had the armor that he had changed in the past, so Su Hengyu could wear it first.

Xie Jing is a lot taller than her, and after she grew taller, her armor as a teenager was kept at home and well maintained by the nurse who took care of her.

Now that this armor is worn on Su Hengyu's body, it really has a bit of the heroic spirit of a female general.

Su Hengyu quickly chose a short knife, and then followed behind Xie Jing with a shield and climbed the city tower.

Looking into the distance, the place where the smoke and dust were billowing was the large army of the Huns rushing towards Luoyan Pass.

"How, are you sure?" Xie Jing asked Su Hengyu in a low voice.

Xie Qingxiao, who was on the side, also heard this, and he paid attention to the conversation between the two with a little attention.

Su Hengyu: "According to the distance, they can trigger it in half an hour ago." Before that, you take someone to set up the things I brought, and when it is triggered over there, you can do it here. ”

Xie Jing nodded yes, turned around and left the city tower.

Xie Qingxiao saw the back of her daughter leaving, and the doubts in her heart were even worse: "What are you two tossing, why can't I understand what you are saying?" ”

"It's okay, the general doesn't need to understand, you just need to watch, and soon you will understand." Su Hengyu smiled but did not speak.

Xie Jing, who left, quickly found the people Su Hengyu brought over this time, and this time in addition to the grain and grass they brought over, they also transported a bunch of cumbersome iron lumps.

After these things were transported out of the tunnel, they were closely guarded by these people, and no one was allowed to look at them.

It wasn't until now that Xie Jing took the jade pendant that Su Hengyu handed over to her in advance, and whispered to each other again, that the group followed Xie Jing to transport the iron pimple to a suitable place.

The thick black cloth was lifted to reveal the cylindrical tube inside.

"Alright, let's start assembling!" The middle-aged craftsman commanded to everyone.

Everyone took action at the first time, and combined these parts that Xie Jing looked strange and strange one by one, forming something she had never seen before.

Everything is ready, just wait for an earth-shattering sound to sound outside, she will lead people to transport these big black guys outside the city gate and launch a blow in the direction of the Hun army!

On the city wall, Su Hengyu looked at the Hun army that was getting closer and closer to them, and waited until their team came within his range, and then secretly breathed a sigh of relief in his heart.

But this is only the first step to achieve the goal, and the most important step is still underway.

The soldiers on the city wall raised their bows and arrows one after another, and the polished arrows were pointed straight at the Hun army in the distance, waiting for the general to give an order, and they were going to take the lives of the other party.

But before that, Su Hengyu's voice sounded: "The general doesn't have to be so nervous, they ran over, or rather, the show is about to start." ”

Su Hengyu's voice fell, and before Xie Qingxiao could ask the meaning of her words, as if confirming her words, there was a change from the Huns.

I don't know where it started, and I don't know what caused it.

After the first loud "boom" sounded, a series of sounds continued to be heard, like thunder falling from the sky.

Everyone only saw the fire erupting from the Hun team in the distance for no reason, and the smoke and flames in the sky swept away like ocean waves, occupying half of the sky.

Even from such a distance, the screams were clearly heard in their ears.

The rumbling sound was accompanied by the vibration of the soles of their feet, which surprised everyone, and if it weren't for the obvious shaking under their feet, they would have thought that the earth dragon had turned over.

And in such a terrible scene, Xie Qingxiao only heard Su Hengyu's cold voice: "Yes, more than a year of hard work has finally been in vain." ”
