During the flight, Li Kongqing lost the packet and consulted Welling:

"I wonder what Brother Welling thinks about the goals and tasks of our squad?"

Welling replied immediately:

"I think Brother Li's main target should be to put some larger strongholds on the original front line of the Xixuan Federation, investigate the situation first, send it back to Iasi, and then continue to the west."

"Yes, it seems that we are on the same page."

Affirmed by Welling, Li Kongqing also made a slight analysis:

"The other side will definitely not complete the demolition of the original forward stronghold, but we also have to think about safety."

Welling nodded with a smile:

"What Brother Li said is extremely true, safety first, merit second.

If you want to talk about military merit value, in fact, if you can join the advance team of the Western Expeditionary Army, you have already obtained a good harvest, and everything else is secondary. ”

Li Lingyou couldn't help but nodded, but then looked at Wei Ling's smiling expression, and felt a little ashamed:

"Brother Welling, in fact, the children of the gate lord family are not all silverfish who only know how to compete for military merit value, and there is a limit when they encounter the enemy......

Welling did not refute, in fact, he also agreed with Li Lingyou's statement in his heart.

In this way, every dozen kilometers, the "totem pole" on the ground and the "Di Ting" relay system in the air are laid down, which indirectly realizes the extension and coverage of the "Jianmu" enchantment system.

Crossing the turbulent Tongtian River, there are still traces of the temporary stationing of the Xixuan Federation a few days ago, flying over the cloudy and mist-churning Mangyun Mountains, crossing the raging Lanjiang River, reaching the rocky Shennu Mountains, and finally camping on the banks of the Mengshui River.

Along the way, no defeated army of the Western Xuan Federation was found, and all the information found was successfully sent back to Iasi.

The Mengshui River was hazy in the night, the sound of the water was roaring, and the Gaoli Bosu Mountains in the distance left a black silhouette in the night sky covered with stars.

Welling offered to be on duty for the night, which made everyone in the advance team feel a little good.

Welling and Shougong placed the cordon farther away, walking around a kilometer radius around the camping place until a complete holographic topographic map was formed in each other's divine senses.

At midnight, Li Kongqing walked to the periphery and replaced Welling.

"Tomorrow after crossing the Gaoli Bosu Mountains, we will soon arrive at the No. 1 target stronghold, Brother Welling had better rest and conserve enough physical strength."

"Okay, I'll go rest by the campfire."

Welling did not refuse the kindness.

Li Lingyou happened to be sitting by the bonfire and did not rest.

Seeing Welling and Shougong coming back, he smiled and lost his bag:

"Brother Welling, don't worry about the fifth brother, he is a wood spirit warlock, much more powerful than me, let's bake the fire, this damn river valley is quite humid."

"Well, I don't worry about anyone but you."

Welling's joking response made Li Lingyou a little annoyed:

"It's just that a genius like me can't touch the side of a mid-level warlock for a long time, it's really depressing!"

"What's so depressed, there's not enough time!"

Welling smiled and comforted:

"Tomorrow to Target Stronghold No. 1, it's closer to me."

Li Lingyou nodded, realized that something was wrong, and became angry:

"Why did you protect me as if you were protecting me, and when I saw the threshold of the middle level, you activated the mind body!"

"Haha!"

Welling couldn't help but laugh.

In the gap of the hat, Shougong also smiled and squinted.

……

The next day, set up the relay system and move on.

Soon after crossing the steam-filled Mengshui River, the terrain gradually rose, and the Gaoli Bosu Mountains were already under the feet.

The Blue Bird vehicle lowered its altitude and moved almost close to the terrain.

From the holographic wartime system data of that day, it can be determined that after crossing the mountains, it will soon arrive at a large stronghold, and the advance team will be named the No. 1 target stronghold.

At the beginning, the Xixuan Federation had deployed a lot of troops and defense systems here, but now it is estimated that there are no large forces, but there should be a small group of enemies.

The vehicle glides lightly over a pass in the mountains.

A few kilometers away, in a valley, a large Federal-style stronghold came into view.

The Blue Bird immediately landed in a col that could not be seen from the stronghold.

Everyone walked down and set up a "totem pole" at the landing site.

Li Kongqing, just in case, preset a call password for the vehicle.

In the event that a quick evacuation is necessary, the vehicle can quickly reach the side of the personnel and transfer in time.

"Brothers, I'll make an explanation first. In front of it is a large stronghold in Xixuan, which we call the No. 1 target, and now the preliminary judgment is that there should be no large troops and heavy weapons in the stronghold, but it cannot be ruled out that there is a small group of enemy troops. ”

Seeing everyone nodding, Li Kongqing continued to add:

"We also don't have heavy firepower and immediate support, if there is a situation where we can't beat it, everyone immediately withdraws and calls in Iasi's long-range strike."

"Why don't you call the remote strike first and then we get in?"

A brother inserted a message.

"What if it's an empty city? Do you think the Empire's long-range artillery preparation costs nothing? ”

Li Lingyou retorted angrily.

"There's no need to argue, just according to the current decision, the advance team will investigate first."

Li Kongqing made a decision.

So everyone didn't say much, turned on various armed scanning and detection systems, and sneaked towards that stronghold in a relatively scattered formation.

Beyond the many cluttered bushes and stumps that had been cut down, the advance party gradually approached the metal fence covered with dark green camouflage lines.

Shougong followed Welling closely, and those autumn-like eyes were all kinds of over-the-horizon detection terminals.

"Childe, through infrared, ultrasound, and laser images, no life has been found in the vicinity."

"Childe, there is an electric current running in the base, and only small electronic devices work on electromagnetic fluctuations."

Welling nodded slightly, his eyes slightly closed.

The world of the source spirit is unobstructed in front of you.

Within a few hundred meters, even the vital features of a mouse could not escape Welling's detection.

The base is a large circle with a diameter of about 500 meters, which is made of prefabricated alloy curved plates and spliced together by mortise and tenon structures.

The height of the fence is also not high, about three meters.

Tall "warriors" and "rangers" are armed, and you can even see the situation inside the walls.

The floor is not hardened or treated with sheet metal, and the prefabricated metal barracks are neatly laid out in the size of ordinary shipping containers.

Hundreds of barracks were neatly arranged, the doors were almost open, and the floors were littered with garbage.

In some barracks, there will be a surveillance camera in a certain corner, swinging slightly towards the passage formed by the barracks.

Most of the small electronic devices detected by the palace are these monitoring devices.

As the crowd drew closer, each armed with its own detection function, it seemed that everyone had found that the stronghold was almost abandoned.

And obviously, this size is at most a medium-sized stronghold.

But holographic data shows that it was originally a large stronghold.

Looking around the wall, there are many bases on the periphery, it seems that it should have been equipped with a lot of military equipment, but now it has all been demolished, leaving only the inner ring layer of the core.

Li Kongqing also reacted, knowing that the team had actually entered the interior of the stronghold, and it was separated from the core area by a wall.

The entire stronghold was silent, and there was no one in the dead city.

Just when Li Kongqing was disappointed and was about to lead everyone to jump into the wall to find out, Wei Ling had a faint warning in his heart, and then a message was thrown to everyone:

"Don't rush in, you feel dangerous!"

All at once everyone looked at Welling.

Welling looked around and found a discarded cannon barrel about six or seven meters long, hidden among the lush vegetation.

"Go to the two powerful brothers, smash one end of that cannon barrel flat, and then poke it into the soil layer and nail it into the ground for a few meters!"

Although everyone was puzzled, based on their trust in the warlocks, especially the intelligent warlocks, they still kept not moving blindly.

Immediately, two "brave warriors" dragged the barrel of the cannon over and placed it on a gun mount that had been discarded from the artillery equipment, and went around to find a huge metal base to use as a hammer and hit one end of the barrel.

"When—when—"

A dull loud bang rang out in the silent valley, and echoes could be heard in the distance.

In a few strokes, one end of the barrel was flattened, and the two of them erected the barrel, smashed the flattened end, and slammed it into the ground, about half a meter deeper.

Immediately, a sergeant carried the metal gun mount, jumped high, and smashed it on the upper part of the barrel.

"Poof—"

The barrel of the cannon went a lot deeper into the ground at once.

After a few successive blows, only half a meter remained on the ground from the barrel.

Welling walked over to the barrel tray and gave Shougong a look:

"Guarding the palace, ultrasound imaging!"

Then with a thin steel pipe, the barrel was struck a few times.

Immediately, Welling lost everyone again:

"Around this wall, again at different distances, the same test data is collected!"

Li Kongqing suddenly realized:

"Brother Welling is so smart, we only see that there is no danger on the surface, but we don't know underground!"

Everyone understood Welling's thoughts and nodded in approval.

In a moment, with the power of two or three "brave warriors", they pulled out the barrel of the cannon that had been smashed into the ground, and smashed it down again in different places at a distance of 100 meters, close to the wall.

The images of the three points coincide to form a three-dimensional structure underground.

In the end, Shougong threw a clear image of the underground to everyone.

The different levels of armament in the empire basically have this ability, but the accuracy may not be as high as that of the palace, and everyone compares the images generated by the palace with their own.

Welling digitizes the data of each detailed point of each sound wave sampling in three dimensions and converts it into an image.

This requires a strong brain numerical memory and synthesis capacity.

After the comparison was correct, Welling affirmed the image of the palace guard:

"The image is correct!"

Looking at the sound wave image, Li Kongqing broke out in a cold sweat.

The image map clearly shows that there are hundreds of small black dots about five meters underground, forming a neat matrix, covering most of the area within the wall.

These black dots are connected by thin lines, forming a kind of interconnected relationship.

Zooming in on any of the black dots reveals that it is a large combined federal anti-infantry and mech mine.
