Unexpectedly, the tunnel was far from being really exposed, and the dragon army suddenly made a commotion, and some of the soldiers jumped from one side of the trench to the other.

The Secret Retreat took it for granted that this was a clear sign that the enemy had sensed the location of the tunnel. So, instead of waiting for the hole to be exposed before launching a surprise attack, it is better to take advantage of the enemy's distraction and act in advance to have a better chance of winning!

So, in a narrow trench, the two sides clashed for the first time.

One side is on the ground and one is under the ground.

One side uses a hook and sickle with a horizontal knife, and the other uses a super long spear made of two guns spliced together.

Separated by more than half a meter of soil, they stabbed each other, and no one knew how many people had died on the other side.

In the trench, the Broadsword Warrior in charge of digging fell to the ground, blood spilling and seeping into the dirt with a grunt.

On the trench, the spear head of the pikeman was also covered with bloody dirt.

The two sides stopped moving, separated by a thick layer of soil, and confronted each other with bated breath.

"Hurry up and save people!" Dugu Wen inspected the trench at his waist, and initially estimated that there were about 200 soldiers killed in the battle, and the wounded soldiers were several times more than the soldiers killed in the battle.

Gotta get them out first!

Hearing the order, the wounded soldiers carefully moved their steps, left the stabbing point, and with the help of their comrades, returned to the ground from a safe section.

The paramedics picked up the wounded and rushed to work.

Long Yuandong's chest was stuffy, he gritted his teeth, and shouted, "Keep digging!"

When digging again, it is natural to avoid the spine section accordingly.

Two meters five.

Three meters!

"Stop!" until the trench was four meters deep, and there was no movement from the secret art retreat. Obviously, the area that has been fought before is the location of the dark ditch tunnel.

"Fill up the explosives!" Long Yuandong decisively ordered. In the ground of the first encounter, the pikemen poked several deep holes with his spear, then ignited the explosives and placed them in the holes.

Boom! Boom!

The earth is splashing everywhere, the road surface is collapsing, and the tunnels are finally revealed! The pikemen did not say a word, but scattered their guns to avoid being preempted by the enemy.

Then, the Broadsword Master unceremoniously threw thousands of grenades into the tunnel!

More than 200 tunnels were completely torn apart by the violent air current!

Unfortunately, the enemy has long since left the tunnel entrance, and even if there are some shocks, I am afraid that it will be very limited. They are not stupid, knowing that the Dragon Army has explosives packs, they naturally will not wait there to die.

"What about people, come out to Lao Tzu!"

"What kind of skill is hiding inside!"

"If you don't come out again, I'll blow you up in one piece!"

The warriors shouted loudly, and as soon as the enemy showed his head, he slashed them into meat sauce with swords and guns!

In the tunnel, there was silence, and no one responded.

It seems that there is a need for more force!

When it comes to hunting, humans have infinite wisdom.

"Let go of the smoke!" Dugu Wenjiao had already ordered someone to clean up hundreds of piles of dry grass and firewood, push them into the tunnel, sprinkle chili powder after wetting, and fan the wind to ignite.

The smoke poured back and quickly poured into the tunnel.

This smoke is so choking that as long as you smell the slightest bit, you will sneeze non-stop. Even the people on the trench were smoked with tears, not to mention the enemies stuffed in the tunnel!

As long as they are not iron-clad, sooner or later they will have to come out!

Unfortunately, the enemy seemed to have been prepared, and a quarter of an hour passed, and the dry grass burned out, and nothing but a faint cough was heard.

The secret art retreat march did not come out in life and death, but the dragon army did not dare to rush in rashly.

Once again, the situation is deadlocked.

Long Yuandong sneered: "If you don't come out, then continue to dig!" casually compared a cross and said, "This time we will dig in the middle!"

The 16,000-strong army was divided into two parts, the inner and outer parts, about 10,000 inside and 6,000 outside. After the tunnel was blown up, the 10,000 people inside were trapped three meters below the dragon camp, unable to move.

The tunnel was very intricately designed, with multiple hidden compartments and baffles, so not only could the grenades not hurt them, but the smoke could not penetrate deeply, except for the hundreds of dead and wounded in the first encounter, they did not suffer much after that.

However, if Long Yuandong is allowed to keep digging, they will be finished sooner or later.

So, they had to save themselves.

The so-called self-help is, of course, not rushing out of the tunnel and fighting the enemy knife to knife and gun to gun. When it comes to hand-to-hand combat, they are no match for the Dragon Army at all. Otherwise, what kind of tunnels are you digging in Rausch?

You must know that the secret art of escaping the march is not as simple as just digging tunnels.

They got this name because they had mastered a stunt:

Desertification of the land!

This is an extremely domineering group attribute fusion technique, which can quickly decompose any nature of mud and stone within its control range into soft fine sand.

And this decomposition process is irreversible.

In other words, the soil that has been sanded by them can no longer be restored to its former state.

This is completely different from the earth attribute skill "Quicksand". The quicksand generated by the "Quicksand" skill is made from the transformation of soul power, and when the soul power disappears, everything will return to the original state.

And the fine sand produced by "land desertification" is real sand!

With the skill of "Land Desertification", the Secret Art Escape March can naturally easily travel underground.

Now, their way to save themselves is to desertify all the land within the boundaries of the trench!

When Long Yuandong had just adjusted his troops and started digging the cross trench again, he suddenly felt a void under his feet, and his whole body fell downward involuntarily.

I saw an area of several square kilometers within the rectangular trench, and suddenly sand and dust rose into the sky, and in the loud bang, tens of thousands of soldiers of the dragon army fell into the ground in an instant.

The land is desertified, why do the people above sink down?

Even if you walk in the desert, you will only sink half a foot at most!

Someone once experimented with three two-meter-high vats filled with fine sand, and on top of the fine sand, an ordinary adult stood on top of each of them. Among them, the person with the first bucket drills with his feet, the second bucket digs with a shovel, and the person with the third bucket does nothing but let people drum into the hole reserved at the bottom of the barrel to see who can step on the bottom of the barrel first.

The answer is that the third person falls to the bottom of the barrel first.

Because the sand in the third bucket, after being poured in by a strong wind, is instantly suspended, and there is no force on each other, and people stand on it, as if they are standing on the void, and naturally fall downward.

When the Arcane Retreat uses the fusion technique of "Land Desertification", a huge amount of energy overflows, enough to cause a terrifying tornado storm that will briefly lift all the sand and soil!

Therefore, all the soldiers of the Dragon Army were buried in the sand, and none of them were spared!

In the sand, you can't see, you can't speak, and outside your ears, it's noisy, and everyone can only fight on their own.

Fortunately, after all, the soldiers of the Dragon Army were well-trained and fearless in danger, and even in such a defenseless situation, they still maintained enough calm.

Some of them first used soul skills or attribute skills to strengthen their defenses;

Some people are full of tacit understanding, and at the moment of falling, relying on the memory of the direction, they form a back-to-back formation of two or three people with their comrades-in-arms;

There are also some people who are earth attribute soul masters, and their perception ability in the sand is no worse than when they are on the ground, so after standing firm, they are not in a hurry to make a move;

There are even some people, as soon as their feet are solid, they immediately fly to their bodies, soar into the air, and drill out of the sand. When it fell again, the storm had stopped, and it no longer fell into the sand, but only on the sand, and was covered by the dust, and there was nothing to do. Long Yuandong and Dugu Wenjiao are representatives of the last type of people.

However, this sandy bottom is not a calm harbor. Inside, there are more than 10,000 elite enemy soldiers who are accustomed to living underground, sharpening their knives and preparing to kill!

Within a few square miles, the Dragon Army has more than 40,000 warriors and thousands of mounts.

The secret art of escaping marching is to stand still, raise your hands and stab randomly, and someone will be automatically shot!

What's more, they themselves have special methods that allow them to distinguish allies in the sand, perceive enemy situations, and act quickly!

The killing officially begins at this moment!
