Chapter 505 Catching the turtle in the jar

Li Yu nodded.

He stepped forward.

At this time, the Xifan army outside the city was feinting attack, shouting and killing sounds shook the sky, and noisy sounds were everywhere. Without the water tank as a helper, no one could hear the movement coming from the ground.

Li Yu walked to the water tank, lay on the ground, and listened carefully.

Even though the water tank acts as an amplifier, it can expand the underground sound to more than ten times or even dozens of times, the dong dong sound coming from this time is also very weak.

When Li Yu got up, the captain intervened and said, "If His Highness hadn't buried these water tanks in advance and sent a dedicated person to guard them, we wouldn't have heard such a small sound no matter what!"

Li Yu waved his hand to the captain and signaled him that he would stop saying these flattering words, and now he has no time to listen.

He turned to look at Lu Fang and nodded to him.

Lu Fang understood.

He closed his eyes and lay down on the ground, his hands pressed against the ground.

The spiritual energy spread out from his palms and continued to extend to the ground.

The surroundings were silent, and people were staring at Lu Fang with big eyes.

After about half a stick of incense, Lu Fang suddenly opened his eyes.

Li Yu quickly stepped forward and asked, "Real person, how about it?"

"The ground is three feet deep, and it has extended into the city!"

Sure enough, digging authentic tunnels!

And it's digging so deep!

Breaking the city by digging tunnels is also one of the common tricks used in the history of Sino-foreign wars.

But the people of the Espanyol are more cunning.

They used feint attacks to hide their intention to dig tunnels, and used water ghosts to attack fishermen at night to hide their intention to attack the southern city.

What the people of Zupan really want to do is to do a two-pronged approach.

While sending soldiers who are proficient in water to swim across the Qin River and sneak attack the southern city, they also sent elite soldiers to sneak into the northern city from the tunnel to disrupt the defense of the northern city.

As long as this two-pronged approach is successful, not only will the south city be lost, but the city defense of the north city will also be in chaos. At this time, the main force of the Xifan Army will launch a large-scale attack from outside the north city, how can our side withstand it?

Li Yu's brain was running rapidly, and he felt headache and tired from thinking.

Fighting war is really a brain-consuming task!

Not only do you need to think about your own layout, but you also need to infer the enemy's layout.

Then, according to the enemy's layout, appropriately modify the layout you have already made.

Such a back and forth, fighting wits and courage.

After a war, I don’t know how many brain cells are exhausted!

Two days later, late at night, the Xifan Army camp was in motion.

A Xifan army of more than 10,000 people quietly approached the Qin River.

These Xifan troops prepared thousands of cowhide airbags and placed them in the river. The soldiers with poor water properties used cowhide airbags as auxiliary and swam towards Huaian City. The soldiers with good water properties did not borrow assistance and dived forward directly without borrowing assistance.

These people with good water properties can dive underwater for three, four minutes, or even longer after completing the inhalation.

First, their lung capacity is indeed better than that of ordinary people, and second, there are also skills.

Before diving, they will inhale continuously, and the air can only enter and exit, continuously compressing oxygen into their lungs. In this way, their time for breathing underwater can be several times that of ordinary people.

This Xifan army, which had more than 10,000 people, silently approached Huaian City along the Qin River.

Because Qinhe has been making trouble in water monsters recently, many fishermen have died. At night, there are only a few fishermen who dare to insist on fishing on Qinhe.

Looking around, the river surface was empty and there was no sight of a ship.

In this way, it will undoubtedly bring great convenience to the night attack of the Xifan Army, and there is no need to worry about the whereabouts of one's side being exposed.

On the other hand, in the camp of the Xifan Army, a group of undead troops gathered outside a camp.

People come in one after another, only in and out.

It was not long since more than a hundred people had entered the tent, but none of them had come out.

This not-so-large camp seems to have become a bottomless pit, and no matter how many people enter, they cannot fill it.

In fact, in this camp, there was a very big hole in the ground in the center, and the undead soldiers entering the cave one by one.

The cave is a downward slope, very deep, and people have to walk for two or three minutes to reach the end.

The tunnel at the bottom is short and narrow, and can only allow one person to crawl through.

The three thousand undead soldiers crawled forward one by one along the narrow pit.

The tunnel extends southward.

Through the bottom of the moat, it extends into Huaian City.

The authentic exit is located in a residential area close to the North City Wall.

The people living here have long migrated to Nancheng, and many of their houses have been damaged by stone throwers. Either a large hole was exposed on the roof or half of the house was smashed.

It can be seen that there are devastations.

The ground of a yard suddenly arched upwards first, and then the arched earth and rocks quickly sank again. It took not long, and a cave more than a half meters wide appeared in the yard.

A small head poked out from the hole in the ground and quickly looked around. Then, the small head shrank back.

One minute apart, a soldier from the Xifan Army took the lead in climbing out of the pit, followed by the second and third...

Ten people crawled out in a row, and no one appeared in the pit.

The ten Xifan soldiers quickly dispersed. Some people entered the house, and some people climbed up the courtyard wall to check the movements around them.

Confirm that there was no one nearby, then a large number of Xifan soldiers began to emerge from the entrance of the cave.

One, two, three, four...

Gradually, the entire yard was filled with soldiers from Xifan Army.

People are next to each other, people are crowded with people, and people are rushing, and they cannot tell the numbers.

There were so many people in the yard, and they began to spread to the surrounding yard.

It was not long before this residential area was almost entirely filled with Xifan soldiers who had emerged from the cave.

The person in charge is the deputy general of the Immortal Army, named Simien.

After all the three thousand Xifan soldiers crawled out of the tunnel, Ximien looked at the north wall of Huaian City not far away. He nodded, waved his hand to the soldiers around him, took everyone out of the residential area, and headed straight for the north gate.

The first thing they came to was the inner gate of the North City.

The defense here is very slack and there are no military guards.

They opened the inner city gate very smoothly.

Looking forward, it was an empty city.

On the outside of the urn city is the outer city gate.

As long as they open the outer city gate and lower the suspension bridge, they can directly put the army outside the city into the city.

Seeing the city relaxed defense, Ximien couldn't hide his excitement, and the Zhou people were indeed unprepared!

He led three thousand immortal gray soldiers under his command and rushed into the urn city and headed straight to the outer city gate opposite.

Simien took the lead and rushed into the gate hole of the outer city gate.

Perhaps because of his excitement, he didn't notice that there was no Zhou Bing who stood guard at the outer city gate, which should have been strictly guarded.

In the city gate, there are dense wooden stakes, which are used to support the city gate.

Looking inside, there were also huge rocks that were built together, and Luo Qi was so high that it completely blocked the city gate.

Simien took a deep breath and said in a deep voice: "Come off the stones and wooden stakes quickly..."

Before he finished speaking, suddenly, countless torches lit up on the walls around the city city.

Looking around, the light balls and torches and pine trees illuminate the city as bright as day.

"ah?"

Seeing this, Simien couldn't help but change her face and she took a deep breath.
Chapter completed!
