In three days, Ye Qing was not in vain, in order to capture Tsing Yi City at the lowest cost, Ye Qing racked his brains.

After all, Tsing Yi City is a small city, with the harvest of more than ten zhang high city walls, and there are hundreds of thousands of troops urgently summoned by Lan Yu, although most of them are rabble, but they can also bring huge resistance to the siege.

Moreover, Tsing Yi City will be under Ye Qing's rule in the future, if this battle slaughters all the young men in Tsing Yi City, then how can Ye Qing rule Tsing Yi City, which is not in line with his original intention.

The best thing is to let the defenders of Tsing Yi City lose the protection of the city wall, and in the case of a field battle, the Ye army is more able to exert its strength and it is easier to recruit the other party.

Not to mention, there is really such a way, to make the soldiers of Tsing Yi City lose the protection of the city wall, first, they go out of the city by themselves, and second, the Ye army goes directly into the city

Then the method of attacking the city is about to come out, it is impossible and unrealistic to ask the defenders to go out of the city by themselves, then only Ye Jun ran to the city, if you want not to be discovered by the defenders of Tsing Yi City, then there is only a tunnel.

Yes, the method that Ye Qing thought of was tunnel warfare.

Tunnel Town has always been loved by soldiers in the Earth War, and has created countless classic battle examples through tunnels.

In the past three days, Ye Qing had already asked someone to dig the tunnel secretly, and now he was almost close to the moat of Tsing Yi City, and he was discovered by the defenders of Tsing Yi City recently.

Although tunnel warfare has not been used in the desolate world, if you dig tunnels under the noses of the defenders openly, people will find out.

In order to cover the excavation of the tunnel, Ye Qing had to gather the army to launch a feint, on the one hand, to train the recruits, and on the other hand, to cover the excavation of the tunnel, killing two birds with one stone.

After another three days, Ye Qing's tunnel has been successfully excavated, the tunnel is not wide, it can only accommodate two people in parallel, but it is enough for Ye Jun's soldiers to pass.

At night, the sky was so dark that I could barely see my fingers.

In the school yard of Ye Jun's camp, there were 10,000 troops standing solemnly, and Bai Yue had just seen blood, and the murderous aura of these soldiers was still there.

Even if he stood so simply, a murderous aura spread in all directions.

Although these days are a feint, but it is also a real sword, tens of thousands of recruits turned into battle, siege the city, veterans pressed the formation, just a few days, the recruits have faded the original youth, began to approach the veterans.

Tonight, these 5,000 people are all dressed in the service of the soldiers of Tsing Yi City, and the spears in their hands are the standard spears of Tsing Yi City. If you want to dress up decently, you can't ignore anything, after so many battles, Ye Qing's army has also collected a large number of Tsing Yi City soldiers' uniforms and weapons, and now it is just in handy.

Ye Qing did not hesitate to abandon the crossbow with amazing lethality for this reason.

In front of the 5,000 army, there were Qin Fei and other officers. It's all armor and ready to go.

"Remember to enter the city, talk less, if you encounter the patrol army in the city, Qin Fei will open your mouth to deal with them. Ye Qing said again.

As the commander of the army, it is impossible for Ye Qing to go to steal the city in person, and his subordinates will not be willing to go to Ye Qing, so Ye Qing has no choice but to let Qin Fei lead the team, and he is becoming a receiver, ready to attack the city at any time.

"Let's go. Seeing that the soldiers all had an understanding expression, Ye Qing nodded with satisfaction, and said to Qin Fei beside him, a group of five thousand people, silently heading towards Tsing Yi City.

In the camp, all the soldiers are ready to fight, just wait for Qin Fei's sneak attack and open the city gate, these troops will directly attack and seize Tsing Yi City.

Composed of 5,000 veterans, the small army of sharp knives led by Qin Fei quickly approached Tsing Yi City after leaving the camp.

Soon after, they arrived near Tsing Yi City.

In Tsing Yi City in the dark, the city gate was closed, and a large number of torches were lit at the head of the city, and by the light of the fire, Qin Fei could vaguely see the patrols moving around the city.

I couldn't help but sink in my heart, it seems that even if the army has been constantly harassing for days, it seems that it will recuperate. The defenders of Tsing Yi City did not relax their vigilance and tightened their vigilance as usual.

It's just that.

Qin Fei would not give up because of this, turned his head, glanced at the five thousand soldiers, and said softly: "Go." ”

With Qin Fei's order, this group of troops began to turn around and head to a remote place.

At the head of the city, it is indeed brightly lit. But the city of Tsing Yi City is tall and long. This length is dozens of miles, so it is naturally impossible to light too many torches.

All, some of the middle of nowhere is very dark.

And the tunnel exit that Ye Qing dug through was precisely in a remote place.

Tsing Yi City originally had its own moat, but after several days of fighting, the places that should have been filled in were filled. Therefore, after Qin Fei and the others approached the city wall, they passed the moat smoothly.

But in this process, Qin Fei and the others were cautious. Regardless of whether it is a remote place or not, the patrol army of Tsing Yi City must have arranged a patrol army on the entire city wall.

If it's a little louder, you'll definitely be noticed. It means not only that the tunnel war has failed, but also that it means the cost. Because under normal circumstances, if you want to break through Tsing Yi City, you have to pay a great price, and that price is something that Ye Qing can't bear.

At this moment, Qin Fei and his troops had already passed through the city wall, basically lined up, one by one close to the city wall, and under the leadership of Qin Fei, they groped towards the dug tunnel.

Soon, Qin Fei groped his way to the vicinity of the tunnel exit.

After arriving, Qin Fei did not speak. He just stretched out his hand and patted the body of the guard behind him. The guards immediately understood and patted the person behind him.

A moment later, ten people gathered. With the spear in hand, start digging.

During the day, the tunnels were not completely dug through, and the last layer of thin soil was left to cover them, in order to avoid being discovered by the defenders when they were patrolling.

Soon, Qin Fei and the others dug up the tunnel exit and jumped out of the tunnel, Ye Qing touched the darkness and walked forward.

Tsing Yi City, the city is tall and difficult to break. The defenders were again above and below the city walls, piling up a large number of patrols. I thought that there would be fewer patrol guards in the city.

But Qin Fei found out that he was wrong, and he was wrong.

After walking for about a mile, Ye Qing and the others found no less than three groups of soldiers patrolling the city. You must know that Tsing Yi City is a place more than ten miles wide.

Lan Yu even arranged such a close army in such a remote place, which shows that he is also quite desperate in order to save his life. Thankfully, it was too dark tonight.

The soldiers patrolling the city had to light torches, otherwise Qin Fei and they would have leaked out a long time ago.

Qin Fei and the others had to move forward cautiously and carefully. And it's getting closer and closer to the avenue. The avenue is empty, and it is difficult to hide people.

Not far from the city gate, a team of sentry came out.

Another hundred, headed by a thousand-commander.

"Who?" exclaimed the Commander.

"I'm a subordinate of the ** general, I was ordered to adjust the defense and pass by here. Qin Fei was shocked, but his face was not obvious, and his voice was extremely calm, hugging his fists.

"Tune the guard, how come I don't know?" the commander's voice was skeptical.

Qin Fei said that it was to prevent the appearance of surrenderers in the city.

But apparently, the commander was very cautious. Repeatedly asked about the source of the order, and did not hesitate to wake up the general in the middle of the night.

"Someone, go and ask the general if there is such a thing. The commander in front of him ordered loudly.

In fact, in the dark, neither side knows how many people there are on the other side, and it is people who speak. Qin Fei could feel it. There aren't many people on the other side.

In addition, if the other party checks it, there is an error. It will certainly lead to a series of consequences. It's better to kill it now.

Anyway, there are only three or four hundred meters left, as long as you kill these people.

You can rush under the city gate, and when the time comes, as soon as the city gate opens, the rest will be simple.

"Kill. Therefore, Qin Fei's eyes flashed with murderous intent, and he shouted.

One wants to move forward, the other to block.

Originally, this atmosphere was tense, and the whole body of the commander was even more tense, and he was very, very wary of Qin Fei and his party, almost at the same time that Qin Fei shouted a killing word, the commander who stayed in front immediately pulled back, and the soldiers behind him also reacted instantly.

All back off.

In an instant, the commander took out the small horn around his waist and put it in his mouth and played it.

Patrolling the camp in the dark, the fastest thing that spreads is sound. Almost every centurion of a patrolling battalion, or centurion, had one.

Now it works.

"Hateful. Leave them alone and rush straight ahead. Qin Fei scolded and ordered.

The soldiers immediately abandoned the men and horses who were chasing this small group and went directly to the city gate.

In the middle of the castle tower, almost at the same time as the commander blew the little horn. The Tsing Yi City guard on duty tonight woke up, and as soon as there was a stir, he could immediately wake up from his slumber, which is the basic quality of a qualified general.

"Bump. When the guard woke up, someone immediately rushed into the guard's bedroom and reported: "General Qiyu, there is no report." The trumpet sounded suddenly, and very closely. ”

"There must be someone making trouble in the city. Hurry up and send someone to check it out. The guard's expression immediately changed, lifted the futon, and stepped out of bed.

This Gangneung City, although it is Lan Yu's lair, has a deep foundation here, but it is not without forces that want to resist. Especially when the army of Tsing Yi City was defeated again and again, Lan Yu was almost unable to suppress the resistance forces in the city, if it weren't for the tens of thousands of troops in his hands, Lan Yu would have died a long time ago.

Today, all the precautions that Qin Fei encountered in the city were actually all blue rain in the city, and there might be people who took the opportunity to make trouble, so they spent so much money.

As Lan Yu's henchmen, the defenders naturally knew these things very well.

Therefore, the guards reacted at the first moment and judged that someone was causing chaos in the city. I didn't expect that some of Ye Qing's army had already entered the city at this time.
