As soon as it was dawn, Lester, Margaret, and Meredith arrived at the mouth of the mine beyond the Shining Silver Mountains.

Excluding the more than fifty young and middle-aged lords in charge of logistics and transportation, with ten Black Guards as the vanguard, five Nightblade Killers as the pathfinders, ten Black Rose Mages as the core, and a hundred mixed teams composed of Noxian Black Iron Guards and Shadow Crossbowmen equipped with some magic steel equipment officially entered the underground world.

The blazing torches illuminate the underground space and dispel the oppressive darkness,

After the mage unlocked the entrance to the underground world blocking the entrance of the third mine, everyone's expressions began to become serious.

Wrapped in rocks, no one knows what lies ahead.

Above the rock formations, several mages with black roses cast illumination magic, illuminating some of the empty caverns below.

Black-gray, dark brown sedimentary rocks are the only color.

Lester looked at the almost vertical rock wall beneath his feet, as if he saw the miner calling out to his 'lordship'.

The miner, 'Gerald', was shot by the crossbow of the Redskin Demon Rat and killed on the rock wall after calling for help, but now the rock wall was so clean that not a single bone could be seen.

I couldn't see the rat droppings everywhere as expected, just like those rats never excreted.

In the darkness, there are hidden evil beasts that eat people and do not spit out bones, and this underground journey is the first active counterattack against the evil beasts.

Thinking that at this moment, there were nearly two hundred people waiting for his order, Lester took a deep breath and said in a deep voice.

"Shadow Crossbowman Crossbow Force Alert, Maurice, begin to set up the rope ladder."

Receiving the order, the five masked Nightblade Killers took down the steel rope ladder that had been prepared long ago from their backs, unfolded the folding steel frame, and drove four steel nails into the hard rock with a hammer, and then drove four steel nails into the rock wall through the characteristic cowhide rope, and the cowhide rope was tightly attached to the steel frame.

After adjusting the angle of the steel claw and fixing the ladder frame, the iron rope ladder is inserted horizontally on the steel frame by means of tenon connection, and the upper and lower are connected together in turn, and gradually lengthened, becoming a semi-permanent ladder structure.

There are two rope ladders on each level of the rock platform, which is convenient for climbers to go up and down, and because it is mainly made of steel, it has a good pressure bearing capacity to allow the Black Guard in magic steel plate armor to go up and down safely.

After Nightblade Slayer went down first, the five men with the Magic Glow Stone scattered to explore the terrain and route, while Lester once again arranged for the rest of the soldiers to go up and down in turn, establishing the first improvised stronghold on the bottom flat ground.

More than three hours later, more than 200 people, including wooden piles and other construction materials, crossed the rock platform of more than 20 meters and came to the top of the flat ground safely, and there was no tragedy of non-combat attrition.

"Margaret, set up a guard camp here, we have to camp step by step, gradually compressing the living space of rats, the situation in the underground world is unknown, the enemy is dark and I am clear, we must not venture in."

"Understood."

Seeing that Margaret had already begun to arrange defense and construction matters, Lester called Northles, a handsome man who had come back first to report the situation.

"Tell me, what did you find?"

Nosles got down on one knee and saluted, then took out a pale yellow linen from his fanny pack, on which he drew a simple map of the terrain with a black dye quill.

Mapping, pathfinding, weapon mastery, and basic assassination principles are all necessary skills that Lester has specially taught and assessed, and they are the skills that every Nightblade Killer must master.

That's why, until now, there were only five Nightblade Slayers.

Sometimes the cultural test is much more difficult than the other tests.

"Look, master, this is a simple map of the area that has been explored."

After handing the linen to Lester, the Northroyce began to explain.

"We are in the very center, with a faulty rock wall leading to the outside world, two naturally occurring underground passages in the upper right and upper left, and a rat tunnel with heavy excavation marks directly above, the height and size of which do not allow us to pass through smoothly."

After a pause, Northles, guessing that Lester might have absorbed his information, pointed to the line on the upper left and continued.

"The passage on the upper left is a little narrow, about two hundred meters away from here, the terrain is gradually lowered, it seems to be a natural cave, stalactites and some other natural underground crystals have been found in the deeper underground Morris, except for some bite marks left by mice, no traces of biological activity have been found, and this passage is currently being further explored by Morris and Didister."

The Nors-Royce pointed to the line to the right, and Lester noticed a strange symbol on the linen.

In Dimaster's description, the passage on the right is open and smooth, and in front of the three-way intersection, he found several black human-faced stone pillars standing on the side of the wall, and the stone pillars have obvious traces of artificial carving, which is the figure he saw on the stone pillars, and he drew them when he communicated with me, and now they can only explore a branch road because of lack of manpower......

Master, are we going to explore the passage on the left first, or the passage on the right? ”

There was a deep groan, but Lester pointed to the rat path directly above.

"Show me this side first."

There was some doubt in his eyes, but the Northles bowed his head respectfully.

"Yes."

……

Any normal person walking in the dark and cramped underground world without the slightest life will experience the depressive despair that makes people crazy.

Unless, that's not a normal person.

More than 500 meters underground.

As Maurice walked ahead, the sound of footsteps echoing through the underground caverns, and the ethereal drops of stalactites in his ears, surrounded by pink and pale blue mica and crystals, the man felt fit to live here.

If it weren't for the master's orders, it would have to be passed on to future generations......

"There is no doubt that many creatures in the underground world have been killed by those rats, and this small hole in the shape of a sharp claw is definitely not something that a big mouse can dig out, and it will not be a small mouse."

Shaking the magic glow stone in his hand, and no longer looking at the fist-sized cave wall, the man stood up and walked over to the crystal, staring at the missing crystal.

"Why are these rats gnawing on these crystals? Teeth grinding? Or is there something else? What's in it for them? Can I take advantage of this? ”

Touching the beautiful sword-shaped sappher, Morris said softly.

“……”

Naturally, he wouldn't answer, let alone answer a question he didn't know how to answer, so he stood still, sensing his surroundings.

Soon, the sound of small footsteps and whispers came from multiple large holes.

"Here we are."

Stuffy gourd said.

Morris put his ear to the ground, closed his eyes, and opened them in an instant.

"It's time for us to go......"
