A group of six people slowly walked towards the interior of the mountain.

The mouth of the cave is like a long, narrow and smiling mouth, swallowing everyone into their stomachs little by little.

Standing on this huge hollow ground and observing carefully, several people easily found a lot of valuable clues.

First of all, there are no traces of moss or shade-loving plants growing on the top, around and bottom of the cave, indicating that this place was originally a natural space inside the mountain, and there was not enough water, light, and other conditions for the growth of shade-loving plants.

Secondly, there are no traces of cave life on the ground, such as bat feces, indicating that this huge cave was originally isolated from the outside world.

In the end, several people could tell that there was a faint smell of sulfur in the air, which indicated that the bottom of the cave was quite deep, and there were even traces of volcanic and magmatic activity.

At the beginning, Wei Ling and Li Lingyou, Shougong and Xiao Duhuo went to the bottom of the abyss of sighs, and there was magma activity that had not solidified, and the breath of the abyss was very memorable.

Of course, due to the large number of rebels and pursuing sergeants and mages trampled on it, there were a large number of intricate footprints and a small number of corpses between the sharp and chaotic stones on the ground.

A few people were unmoved and moved forward cautiously.

The light grew dimmer and darkened.

Shougong still lit a small lamp on his forehead to give the rest of the people a little basic light.

As the few people went deeper, the space inside the cave became more and more empty, and the occasional sound of the stones under their feet being stepped on would bring a long-lasting reverberation.

The cavern was deep downward, dry and silent, with no sound except for the slight breathing and footsteps of a few people.

As he walked, Welling found that the ingots had subconsciously pulled the corners of Welling's clothes.

It's still the child's heart back then, Welling laughed secretly in his heart.

It's really interesting to say, although Yuan Bao is a mid-level powerful warlock and a fierce beast, his heart is not calm, like a half-grown boy, and he is still a little timid.

As they moved quickly, they felt that the distance had left the mountain and entered the ground, the air pressure and temperature were rising, and the sulfur content in the air had increased significantly.

However, the strange thing is that the underground cavern space has become even larger, and the ground under your feet has become no longer rocky, but covered with various rock fragments, just like the Gobi Desert outside.

Many of the sergeants killed in the pursuit and counterattack still glowed from the lights on their armament and supply platforms, shooting beams of light in all directions, strong and weak, cutting the darkness of this vast underground space into a dim outline.

It wasn't until the six of them walked for two hours that they had gone nearly 20,000 meters underground, and what they saw made several people a little incredible.

The underground space can no longer be said to be magnificent, it is simply another world.

The dome, which is made of rock formations, has no supporting columns in sight, but there are no signs of collapse.

The ground had turned to flat gravel, soft and hot to step on.

The temperature of the air is quite high, and natural people can no longer live in such a world for a long time.

The most bizarre thing is that in the distance slightly downward, there is a slight scarlet light.

Welling looked closely, and these glimmers were naturally emitted by some ores at high temperatures.

Wang Mantuo was already a little dumbfounded, and wiped a handful of beads of sweat from the corners of his forehead:

"It turns out that there are huge holes in the ground in some areas of the home planet, and it turns out to be true."

"Brother Wang still switched to an energy body, otherwise it would be too hard."

Yuan Bao gave Wang Mantuo advice.

"No, Yuanbao, I'm a fire spirit warlock, and I'm not afraid of this high temperature."

"Look at that huge rock!"

Welling spotted a stone dozens of meters high in front of him, outlined by the distant glimmer and peeled out of the darkness.

Several people quickly ran to the boulder, and the scene in front of them was stunning.

This is not a boulder dozens of meters high, but a huge figure with an ancient and minimalist shape, with only a head, and its body cannot be seen.

It is also unknown if the stone statue only has a head, or because the body is buried under the gravel.

At this moment, Shougong used over-the-horizon images to throw more forward images to everyone.

The space underneath has become a plain with no end in sight, still stretching downward, and there is no end in sight.

Similarly, there are many huge stone statues of heads in the distance, scattered irregularly in the distance.

In the distance, a scarlet mist swirled.

In addition to the conventional atmospheric composition, there are methane, ammonia, sulfide gases, and some unknown gases and dusts.

Just over this vast plain, there are all sorts of crashed small vehicles, some of which are still emitting black smoke.

The Helbon sergeants who entered this place, the federal mages who helped in the battle, and the armed men who defected, almost all became dead bodies, and died in different directions in all kinds of strange appearances.

The most bizarre thing is that none of these corpses are facing the direction they came, they are all facing the distance.

Faced with this nightmare-like scene, Welling's face became very solemn:

"You can't go any further!"

"However, my seventh brother is still inside......"

Wang Mantuo's face became ugly, and he had a sense of foreboding.

"Let's go look at the two bodies and analyze the cause of their deaths."

Li Lingyou also energized his body and floated into the distance.

A few people followed, taking a closer look at the Helbon police officers who were next to each other.

The dead sergeants seemed to be dying very quickly, and there was no sign of struggle on the ground around them.

They all have federal-style weapons on their bodies, which are supposed to be effective in protecting their fragile bodies, but there are a few holes in the body, which attract the attention of Welling and others.

The hole was very smooth on the armor that had been pierced by an unknown force, leaving no signs of cracking inside, and there was no sign of metal melting, as if the original material in the round hole had disappeared in an instant.

The sergeant's body, which corresponded to the hole in the vehicle, disappeared as strangely as a small cylindrical body, and then blood spilled out of the hole, filling the body and inside the armament.

This kind of slaughter is a bit like a penetrating wound caused by a high-energy laser weapon.

However, unlike the damage caused by laser weapons, there are no high-temperature burn marks found on the edges of the muscle holes.

According to the height, position, hole location, and fall position of several people's vehicles, Welling instantly deduced the picture before their death:

More than 1,000 police officers marched forward in an extremely scattered formation, but at a certain moment, a dense and unknown attack suddenly issued from afar.

This attack, almost without any divergence, was like a rain of fire, shooting in parallel, all the bodies, weapons, and vehicles, could not stop the moment of the rain of fire, so, in that instant, more than a thousand people died together.

All the vehicles fell, all the sergeants fell together, every mage didn't have time to transform into energy bodies, and more than a thousand people fell silently and fell to death.

Receiving Welling's deference information, several people's hearts sank.

Shougong nodded:

"As Childe guessed, the very bizarre attack method is most likely caused by energy weapons."

Liuxi River Analysis:

"There's a question, what kind of energy weapon can deliver such a dense attack?

As far as I know, all of the Stronghold Energy Cannons, Energy Phalanxes, and Directed Energy Phalanx on large vehicles don't have such a wide coverage, unless they are attacked in batches.

But this brings up another problem, so after the first attack, there will be frightened sergeants who turn around, and then the direction in which they will fall will not be so uniform.

Therefore, Brother Welling's opinion should be correct, and all indications indicate that these men all died at the same time.

Moreover, we are not sure that there will be such an attack.

Therefore, we are not in a good position. ”

Welling commanded:

"Yuanbao, go to the nearest stone statue to see if there are any hollows that have been affected by the attack."

Yuan Bao nodded, and instantly appeared next to a tall stone statue nearby, hovering in front of the stone statue, carefully observing whether there was a similar attack gap on the stone statue.

Looking at the ingots that kept shaking their heads, Welling felt even more miraculous:

"Actually, there are no holes in the stone statues I saw earlier, so can it be said that those magical attacks can actually not hurt these stone statues?

Or are those attacks only effective against organisms and metals? ”

Shougong's view is:

"I think the second possibility of Childe's analysis is greater, and there is no reason to explain that the energy attack still has the reason to let go of the stone statue in a humane way."

Wang Mantuo made a guess based on the existing situation:

"So, can we conclude that all the attacks are against another military system that we have not been exposed to, and are directed at our forces and humanity on the surface?"

Even if the light was so dim, it could be seen that Wang Mantuo's eyes were a little red.

Welling nodded and patted Wang Mantuo's shoulder:

"You're right here, I'll go ahead and see it personally.

I feel that Wang Guangbai and the two of them, under normal circumstances, should have taken a small vehicle with the commander, and you should focus on those vehicles, and you may find them ......

However, I am not optimistic about the results, and I guess they will not be spared! ”

A few people no longer insisted on being stubborn, and dispersed on the spot, going separately to inspect the small vehicles that had fallen, and as for the few ships in the distance, they were handed over to Welling.

Welling's body shook, and he flew over a distance of several kilometers at once, flickering left and right, and quickly inspected several small vehicles.

Inside one of the vehicles, second only to the medium-sized vehicles, Welling spotted Wang Guangbai.

The familiar fierce face, the scar on the forehead is still the same, and the expression has no horror, just a kind of surprise.

There was also a corpse wearing the imperial warlock robe next to Wang Guangbai, which should be Cui Yinchen from the Cui clan in Qinghe, and his young face was full of incredulity.

Wang Guangbai had at least four fatal holes in his body, so he didn't have time to avoid any protection.

Cui Yinchen only has two holes in his body, but the most helpless thing is that there is a hole that runs diagonally through his head.

There were also several commanders of Xixuan on the vehicle, and the causes of death were similar to those of Wang Guangbai and Cui Yinchen.

Although he had an unhappy past with Wang Guangbai, Welling was still a little sad about their sacrifice.

Inside the inclined vehicle, he found the body bag that came standard with the armed vehicle, packed the two of them, clamped them under the flank, and flew back to the place where the men had previously discussed.

As soon as he saw Welling returning and the two body bags he was carrying, Wang Mantuo's tears fell and he choked up.

Putting down the bodies of the two, Welling looked at Li Lingyou and Liu Xihe:

"You go back out at once, send them back to the vehicle and freeze them, I'll take a look deeper, I have to have some useful information to report, I can't really go back like this."

"Master, then I'll go with you."

"Alright, come with me, keep an eye on the body transformation."

Wang Mantuo picked up a corpse and turned around with tears in his eyes.

Liu Xihe also picked up another corpse and walked in the direction from which he came.

Li Lingyou and Shougong looked at Wei Ling, nodded, and then returned.
