This game is so weird!

"Well done!"

Marcus walked over and patted each of the four players on the shoulder. Several consecutive battles had made him feel increasingly favorably toward these extraterrestrials.

Resourceful and quick-witted, able to find solutions to break the deadlock in battle.

More importantly, like him, they are fearless and adventurous. Even if they were placed in the Gears squad of the Security Government Alliance, as long as they do not suffer any unexpected casualties, they would definitely become elites fighting on the front line.

The group observed the cave, which had become a hatchery for the orcs, for a while. After the collapse had just stopped, a few rocks were still vibrating slightly, and the orcs that hadn't been crushed or the larger larvae were struggling to crawl out from under the rocks.

However, the vibration of the stones stopped not long afterward.

The collapsed rocks and the biological fluid from the crushed insects and their eggs blocked the gaps between the stones. As a result, no gas could pass through this liquid membrane to reach the area beneath the rocks, and countless beastmen and larvae that were still struggling to survive were suffocated to death.

Seeing that the cave had returned to calm, Little Black took the lead and led several players back into the cave to check it out.

Except for a few egg pods hanging on the rock face that survived, all the other insect eggs placed on the ground were dead beyond any hope of survival, and even many of the unknown machines set up by the Orcs were damaged.

Wooden Fish, who came with the team, took out his scanning gun and scanned the area. He could only see the biological slime-like insects and could not identify the species. On the contrary, several orc machines were successfully scanned.

Most of them are biological incubators that can maintain the temperature and humidity of the surrounding environment, and there are also a few larval feeders with specially formulated feed.

No equipment for insect egg production or orcs was found. Either these insects were produced naturally, or the relevant facilities are not located here at all. This is just an incubation factory built on the front line to supplement combat power.

However, the descriptions scanned by the machines surprised Muyu; they were all biological research instruments from the Security Government Alliance.

With that in mind, Muyu squinted and pondered for a while before catching up with the main group along with Xiaoxiaohei, who had finished dealing with the remaining egg pods, and heading towards the deepest part of the mine.

The rest of the journey was unusually smooth, without any danger, and we arrived at the deepest mining pool on the map without any problems.

At the end of the passage is a cliff in the middle of the cave where the ore pool is located. Standing on the edge of the cliff, you can look down at the entire ore pool.

Night Rain walked to the edge of the cliff and, like Marcus, leaned on the railing and looked down.

Em energy, emitting a yellow glow, spewed from several dragon holes in the rock wall, flowing slowly through cracks in the ground at the bottom of the cave like underground magma.

Under the yellow light emitted by Im Energy, the entire cave turned golden. The flowing and changing light reflected on the bizarre cave ceiling, making Ye Yu feel as if it were a developed and illuminated karst cave landscape on Earth, giving her a dreamlike feeling.

"It's beautiful, isn't it?"

Marcus glanced at Night Rain's expression and slowly said, "We fought a 79-year civil war for these beautiful things. The war had just ended when the orcs began their invasion on the day of the incident."

"In the 93 years since the mining of Im energy began, there has not been a single moment of peace on Sera."

Ye Yu's expression was a little stiff.

This stuff is like oil on Earth; wherever it's present, mold will grow, and then a great battle will break out, leaving only humans injured, right?

"Doesn't Sera have oil?"

Upon hearing this, Muyu asked curiously, "The train we rode before didn't seem to burn Im energy; it was more like a steam train that used both coal and diesel."

"Oil? It used to exist, but I heard it disappeared before I was born. Apparently, it was used up by various countries."

"Ultimately, it's just a special kind of underground mineral, and like this Im energy, it will eventually run out. After the oil runs out, this Im energy will appear underground..."

Before Marcus could finish speaking, Bard chimed in. After inspecting the mining pool, he felt something was amiss and walked over to the group, saying, "Friends, how about we go down and activate the resonator before we talk?"

"The situation below is a bit strange. Apart from a few oddly-looking beastmen laborers, we haven't seen any enemies."

"Does he look strange?"

Night Rain stepped forward, picked up the corpse of the beastman laborer from the ground, and examined it.

On the way down, these conscripted soldiers launched a fierce attack on them, charging through a hail of bullets as if they didn't care about their own casualties. The closest one even rushed in front of them.

This is quite different from the previous situation where orc laborers would actively flee and lie in wait to attack when at a disadvantage.

Just as Bard had said before he came down, these conscripts looked rather strange; their eyes and mouths were filled with a bright yellow light that did not disappear even after they died.

"Could this thing be used as an angel of light in a church, haha?"

Little White used its pry open the mouth of a laborer and shone it around like a flashlight, while Little Black, standing nearby, laughed so hard it almost fell to the ground.

"You know what, given the prevalence of cults over there, you might actually be able to become an angel in some small sect."

They piled up the corpses of several conscripted soldiers together, preparing to take them back to the guild for research. The group followed Marcus and Bard all the way to a riverbank on the edge of the underground Im Energy River.

Below was the endless expanse of Im Energy. Unlike the pungent smell of gasoline or paint that Ye Yu had imagined, a strange, almost sickly sweet aroma wafted over.

Under the watchful eyes of Marcus and the others, Night Rain and the players took out various bottles from their bags, leaned over the edge of the cliff, and filled the bottles with their hands. They did this several times before stopping.

"What are you going to do with all this?"

"Haha, this is the first time I've seen this. I'll take it back and study it..."

Before Muyu could finish speaking, he peered into the river and suddenly saw a huge shadow approaching him from the not-so-transparent bottom.

"Um, by the way, are there any living things in this Im Energy?"

"Im energy is highly exclusive; no living organism can survive in it."

The wooden fish swallowed hard, slowly withdrew its hand from the river surface, and said slowly:

"Then... what's in this water?"

"Gah!"

Eight enormous shield claws burst from the water, swung through the air, and then grabbed at the rocky embankment on the shore. The giant claws, covered in Im energy, shimmered with the same yellow light as the conscripted soldiers.

"Run! It's a burrowing beast!"

Seeing the beast's claw leap out at his face, Mu Yu was startled and ran backward while shouting. When he passed Marcus and saw that he didn't move, he reached out and pulled him back.

When he looked back after running far away, he realized that what he thought was a burrowing beast lying in ambush at the bottom of the river was actually trying to struggle to climb ashore. Its shield claws completely ignored the humans on the shore, weakly sliding and leaving marks on the bank. Finally, under Marcus's gaze, it fell back into the Im Energy and sank.

"It's been corrupted by Im energy, a rust disease. Even the beastmen aren't immune...?"

Marcus, unfazed by the danger, had already noticed that the Burrower was not in good condition. He remained standing on the shore in his original posture, his eyes revealing a deep thought.

A moment later, after the players tentatively filled the bottle with Im energy again, Marcus turned to Bard and said, "Activate the resonator, then retreat."

Bard, who had already found a suitable position, nodded.

"I set the countdown to 45 minutes, let's go!"
