The group did not dare to slack off, and quickly returned along the same road.

However, just as he was about to come to Sui City, the eyes of the leader of the border area suddenly widened, and a look of horror appeared on his cheeks.

Because of the front, Huyan Hammer had already taken many barbarian soldiers and began to attack the city.

"Oh no!

Under the fright, the voice of the leader of the border area couldn't help but tremble a little.

"Now in Sui City, the army is empty, I'm afraid it won't be able to resist the attack of the barbarians at all! It's just that this Huyan Hammer got the news, how could it be so fast!"

At the end, the fists of the leader of the border district clenched suddenly.

Nie Yuantian on one side seemed to understand the border leader's concern, he smiled slightly, and said softly: "You don't have to worry, before I came here, I guessed that such a thing might happen. ”

"So as early as yesterday, it was ready. ”

"Ready?

The leader of the border area was stunned, and his eyes also showed a hint of hope, and he looked at Nie Yuantian.

"I asked people to bury ** in front of the gate of Sui City. ”

Nie Yuantian smiled slightly, and said softly: "If these barbarian soldiers don't come to attack the city, it's fine, if they come...... It must be that they can't eat, so they will go around!"

As if confirming Nie Yuantian's words, when his words fell, a shocking noise suddenly broke out in front of the gate of Sui City.

At the same time, the flames filled the sky, and a huge mushroom cloud rose up.

Huyan Hammer, who was besieging the city, obviously never expected that such a change would happen.

When he came back to his senses, he only saw that the many barbarian soldiers who had just attacked the city had already been killed and wounded.

"Damn, how could this be!"

Seeing this scene, Hu Yanhammer couldn't help clenching his fists, and his eyes contained anger and resentment that could not be concealed.

"My lord, it's not good!"

Just as Huyan Hammer was about to gather people and continue the siege, a soldier rushed over with a panicked face.

"My lord, someone from the Xia Kingdom has appeared behind him, and he is launching a fierce attack on us!"

"Not good!"

Hearing this, Huyan Hammer's face changed wildly.

"Attacking from the front and back, if we are encircled, we can't run away if we want to!"

A look of panic appeared in Hu Yanhammer's eyes, he didn't dare to hesitate, and hurriedly said: "Retreat now to avoid falling into the encirclement!"

When the words fell, Hu Yanhammer dared to hesitate, turned around and left.

Even the leader and the main general left, and the many barbarian soldiers around him, where did they dare to continue to stay here, just a few moments later, many people before Sui Cheng had disappeared without a trace.

Seeing that the crisis in Sui City had been resolved, the face of the leader of the border area instantly showed a touch of relief.

He turned his head to look at Nie Yuantian beside him, and there was a look of gratitude on his face that couldn't be concealed.

"This time, I really thank General Nie. ”

The leader of the border area arched his hand at Nie Yuantian and said softly: "If it weren't for your strategy, I'm afraid that today, Sui City would have been lost." ”

"It's just what I'm supposed to do. At the time, I was just in case. I didn't expect it to really come in handy. ”

Nie Yuantian smiled slightly, paused, and said again: "It's just that the most important thing now is to find out the traitors in Sui City." ”

"Mole?"

As soon as these words came out, the leader of the border area was stunned.

When he came back to his senses, a flash of anger immediately appeared on his face.

"What does General Nie mean is that there are traitors of the barbarian kingdom in our Sui City?"

"Not bad. ”

Nie Yuantian nodded, and his face became extremely serious.

"Think about it, how long have you been away from Sui City, it stands to reason that it is impossible for Huyan Hammer to reach Sui City one step ahead of us!"

"But he seems to know that Sui Cheng is empty, and after seeing you come out, he immediately attacked Sui City, can't this be a problem?"

"And what are you going to do?"

The leader of the border area nodded slowly and said in a deep voice.

"If you gather everyone, you will say that you will take advantage of the fact that Huyan Hammer has just failed and the army's morale is unstable, and attack the enemy army and let everyone gather. ”

A smile appeared on Nie Yuantian's face, and he said softly.

Naturally, the leader of the border district would not refuse, and immediately agreed.

And just when Sui Cheng gathered everyone, Huyan Hammer had also returned to the barbarian station.

A look of anger that could not be concealed appeared on his cheeks.

He clenched his fists and cursed angrily: "What kind of bullshit traitor, there is a ** ambush, and it was not investigated in advance, it is really not credible!"

"This matter is indeed my negligence!"

Just as Hu Yanhammer's words came out, a voice suddenly sounded.

A figure walked in from outside and said softly: "This **, I didn't know in advance, and even not only me, but the entire Sui City, there are very few people who know about it." ”

"If my guess is correct, it should be Nie Yuantian's plan. ”

If there is someone from Sui City here at this moment, I am afraid that he must be able to recognize it, this so-called traitor is the deputy staff officer!

"This Nie Yuantian is scheming and calculating. ”

The deputy staff officer took a deep breath and said in a deep voice: "Just now he has already summoned us and is preparing for a sneak attack, you must be careful." ”

"What a daring to sneak up on me!"

Hu Yanhammer snorted lightly, and there was murder in his eyes, "I'm just believing you once! If Nie Yuan is innocent, I will definitely let him come and go!"

"That's good. ”

Seeing Hu Yanhammer's reaction, the deputy staff officer nodded, "I can't stay long now, I'll go back first." ”

When the words fell, the deputy staff officer didn't hesitate at all, turned around and left.

Moving forward like this, the deputy staff officer soon came to the front of Sui City.

But in the next second, his brow furrowed.

Because at this moment, he was shocked to find that the gate of Sui City was tightly closed.

"Open the door!"

The deputy staff officer shouted loudly.

"Oh, want to come in?"

A voice full of ridicule suddenly sounded.

Nie Yuantian slowly walked out of the gate with many soldiers.

His eyes were fixed on the deputy staff officer, and he sneered.

"It's so late, deputy staff officer, you are still going out, are you going out to admire the moon?"

"What nonsense are you talking about!"

The deputy staff officer shouted loudly, but between his eyes, he couldn't help but have a look of panic.

"I didn't clean the battlefield carefully, I just wanted to take a good look and figure out the enemy's strength!"

The deputy staff officer said in a deep voice: "Now you get out of the way immediately, I'm going back to rest!"

"Go back and rest?"

Nie Yuantian laughed, "Okay, naturally it's no problem." However, you can go in, but you can't go back to the barracks!"
