Ye Haixuan looked forward along Liao An's hand, and sure enough, the fire in front of him was much brighter.

"All of you, stay where you are, don't move, wait for my orders!"

The 10,000 men continued to keep their eyes open and look at the firelight in the distance, when suddenly the commotion in front of them stopped, and there was a sound of banging.

"Great Commander, this ......" Liao An's face was surprised, and he looked back at Ye Haixuan inquiringly.

"Wait. ”

After Mo Yue's time of sticking incense, the sound of striking iron in front of him became regular, and Ye Haixuan also moved his body, ready to check it.

"Liao An, you take a few people with me, and the rest are on standby!"

Liao An followed Ye Haixuan forward quickly, and when he reached the Hengduan Mountain Range for about a mile, Ye Haixuan stopped.

"The Grand Commander?"

"Shhhh......h

"This time, the task is to find out what the hell they are doing here. Find out where the sounds of striking iron came from and what's in them. Don't expose yourself, and definitely don't let them know we've been here!"

These people all have rich experience as spies, and they are all brothers who were born and died in the Tiger Ben Camp with Ye Haixuan before, and now their skills have also come in handy.

"Guaranteed to complete the mission!"

After the two dispersed, Ye Haixuan and Liao moved forward quickly, and the closer they got to defend the city, the more careful they became.

Liao An suddenly noticed that there were two soldiers patrolling in front of Ye Haixuan, the two looked at each other, and tacitly went around behind the two soldiers, Ye Haixuan and Liao An stretched out their hands on the soldier's head at the same time, and when they broke to the side, the soldier fell softly.

The two dragged the soldiers into the grass, changed into their clothes, and patrolled the doorway.

Suddenly, there was a voice ahead.

"Grand Commander!"

"Well, nothing is out of the ordinary. ”

"Archon, nothing unusual, as usual. ”

After the voice left, Ye Haixuan and Liao An found themselves in a cold sweat.

"Wan Yan Fei?"

"Yes, he's here too. Looks like we guessed right. You'll have to sneak in and see what they're up to. It's just that we are not familiar with the offensive and defensive map of the Hengduan Mountain Range, which is a little difficult to do. ”

Ye Haixuan's words, Liao An agreed very much, and the two could only wait for the opportunity to move, otherwise they would likely be exposed.

The other soldiers were in a similar situation, waiting for their opportunity.

"Boom!"

A loud bang suddenly erupted from the defending city, Ye Haixuan and Liao An tensed, staring at the direction of the voice coming from the defending city: "Great Commander!"

"It's now!

Taking advantage of the panic inside, the two grabbed two handfuls of mud on the ground and smeared them on their faces and rushed in.

It was already a mess inside, everyone was running, and the two of them didn't know why, so they grabbed someone at random.

"Brother, what's wrong!"

"Hurry up and bring the water! there's an explosion in the cave!"

After the man finished speaking, he rushed into the team, Ye Haixuan and Liao An glanced at each other, and followed to carry the water, heading in the direction of the flow of people.

As far as the two of them could see, a huge cave appeared in front of them, and Ye Haixuan was stunned on the spot.

"What are you doing here! Don't go in and put out the fire!"

With a fist on his head, Ye Haixuan looked back and saw that it was a person dressed as a centurion, and quickly nodded: "Yes!"

Liao An and Ye Haixuan rushed into the cave regardless of the danger, and it was so dark that they couldn't see the edge.

"Are you stupid to stay outside for a long time!

With another punch on his head, Ye Haixuan held back his anger and deeply remembered the man who had a mole on his face who had beaten him twice.

After splashing the water in their hands and dragging out a few more construction people, Ye Haixuan and Liao An were exhausted.

"Commander, let's go. Liao An saw that the fire was already small, and said to Ye Haixuan.

After the discussion was made, the two returned to the outside of the city, returned their clothes to the bodies of the two city guards, and set a fire to burn the door clean.

"Centurion, there's a fire at the door!"

"Why are you still stunned!

Ye Haixuan and Liao An hurriedly ran to where the army was, and when the two arrived, they found that all the people sent out had returned, and there were quite a few.

"It's really hard for everyone today, let's hurry back to the camp, don't let them find our traces!"

The group sneaked back to the Celestial Empire camp again.

"Oh, my commander, how did you become like this!" After His Royal Highness the Crown Prince slept comfortably, he originally planned to go to Ye Haixuan to discuss the next matter.

Unexpectedly, he was told by the people around him that Ye Haixuan went out to do a task.

Finally, when Ye Haixuan came back, the sun had completely set. And Ye Haixuan was also dirty and tired, and His Royal Highness the Crown Prince almost didn't recognize it.

"Don't talk about it, let's go put out the fire. Ye Haixuan beckoned, and those spies followed him into the camp of the Grand Commander, and His Royal Highness the Crown Prince immediately sent someone to find the prefect to come over.

"Brothers have worked hard today, take a break, and then summarize all the news you hear one by one. ”

When the prefect arrived, he was shocked to see that they had just returned from the refugee camp.

"Commander, let me start by saying that this place seems to have been turned into an old city by the neighbors, and the tents are ready-made and in good order. ”

Ye Haixuan nodded: "You come." ”

"There was a fire in the middle, probably caused by a firecracker explosion. ”

Ye Haixuan said suspiciously: "Firecrackers exploded, and firecrackers were still set off in the barracks?"

"This subordinate doesn't know......"

After asking one by one, Ye Haixuan probably understood what the neighbors were doing here, sighed deeply, and sat down on the chair.

"Why do you look like this? I don't know, I think you've lost a battle. "His Royal Highness the Crown Prince doesn't know why, these news sound very ordinary, and have no reference value, I really don't know what the neighboring people are doing there.

"If I don't take action, I'm really going to lose the battle, or a big defeat!"

Everyone was puzzled, Ye Haixuan supported his tired body and came to the sand table map.

"This is the Hengduan Mountain Range, and this is the Shangjing of the Celestial Empire, the distance between the two is in a straight line, and it can be reached in ten days by a rapid march. ”

His Royal Highness the Crown Prince nodded: "We all know this, but the Hengduan Mountain Range is covered with snow all year round, and they can't take this road." ”

"No, they have a way to go down that path now. Ye Haixuan hit the sand table model of the Hengduan Mountain Range with a fist: "The piece of land they circled has opened a bottomless cave. They didn't think about going over the hill in the first place!"
