"The Abyssal Vein of Starfire City is a very special place, it existed in the magical world long before the Cataclysm. Pen ~ Fun ~ Pavilion www.biquge.info"

"At that time, because the magic guide machine technology had not yet developed and spread, people only collected ordinary iron ore in small quantities on the first layer of the abyssal vein. ”

"Later, after the development of magic guidance technology and card making technology, the various rich mineral deposits of the abyss vein were recognized and explored. Along the way, Ye Yu slowly told the two on the side about the history of the abyss vein.

"Then why is it special?" asked Fei Ye curiously.

"Because of its renewability. ”

"Huh, what do you say?"

"There are some ores in the Abyss Vein, every time you have collected them once, and come back after a while, you will find that the ores have reappeared in the places where you were collected, although it may be different from the last time it was collected, but after all, it is equivalent to regenerating it. ”

"There is such a wonderful thing!" Fei Ye exclaimed, and even Youlan was a little sideways when she heard it.

"Yes, no one knows what the reason is, the upper echelons of Spark City even sent someone to investigate, but there is no result. Ye Yu smiled.

"But there was one person who went to observe this phenomenon. ”

"There was once a magician who found such a place and stared at it every day. Later, he discovered that the ore slowly grew out of the rock and soil like a plant would grow, and finally became a place to collect again. ”

"Like a plant growing?" Fei Ye whispered, "It feels like it's funny." ”

"Oh, of course, there are some wonderful things. It is said that ......"

In fact, Ye Yu is a very talkative man, perhaps because of his personality, he is not like most card makers, giving people a deep and introverted feeling.

Along the way, Ye Yu kept telling about the abyssal veins or strange or strange things, interspersed with some precautions, and the group talked and laughed, but they also quickly reached the second layer of the abyss veins.

Unlike the first floor, the second floor is a dark brown soft mud floor, and the soil here is soft, and if you step on it, it will be like stepping on sand, and your feet will sink slightly unconsciously.

"It should be on this layer, although this layer has been cleared by Starfire City, there are still some small monsters, but they shouldn't cause us much damage. ”

"I'll collect some black rocks in this place first, and you can search around here a little and see if you can find a gate made of black iron. Saying that, Ye Yu also gestured, indicating that it was a wide giant gate, "There will be things we want in there." ”

"Hmm. When it came to the task, Fei Ye would become very serious and listen carefully to Ye Yu's instructions. And Youlan is an iceberg face that has not changed for thousands of years, but there is also a little vigilance in his eyes.

"Let's do it. After saying that, the three of them slowly dispersed.

Black rock, a pitch-black rock found in abyssal veins, is found in almost every layer.

"Hey, portable miners. Ye Yu took out the portable miner from his backpack with difficulty, although it was said to be portable, its actual weight was not light.

The heavy miner is placed on top of a black rock, then a magic card is inserted, the relevant data is entered, and the miner is up to work with a bang.

In a short time, a large chunk of black rock had been collected, and after a rough removal of the magazine, several small pieces of black rock were spat out from the large mouth at the front of the miner.

Ye Yu casually packed these black rocks and put them in his backpack.

This time, I want to make a costume card for Yulan, and before that, I need to make a whole set of armor first, so I don't need a lot of black rocks. Just the material of black rock is estimated to cost more than ten kilograms.

"Hey, I'm going to be tired. Looking at the increasing number of black rocks, Ye Yu said to himself with a bitter face.

In a short time, Ye Yu had already collected a full ten kilograms of black rock, and Youlan and Fei Ye also returned to their side, and after asking a little, they had successfully found the black iron gate.

Putting away the miner and carrying his backpack, Ye Yu followed them towards the black iron gate.

After turning several passages, the bright magic guide crystal lamp above his head slowly became dim, as if he had walked to a secluded path, and after turning a corner again, a huge black iron gate appeared in front of Ye Yu.

Near the silver-white life-saving table, a huge iron door flashed simple, all black, and a red warning sign was hung on the door, and the bright red "Danger One" indicated that this was a first-class danger area in Spark City.

"There are many of these dangerous areas in Starfire City, and most of them are enclosed, and if you want to enter these areas, you must have a badge issued by the Card Maker Guild or the Wizard Technician Guild. ”

As he spoke, Ye Yu took out the black iron badge he had obtained through the card maker trial from his pocket and slowly put it in the depression of the black iron gate.

The size of the Black Iron Badge was just right, and Ye Yu embedded it and turned it hard to the right, and then pushed the gate hard.

Listening only to the sound of "squeaking", the door was slowly pushed open, revealing a dimly lit passage, dark with no end in sight.

"Huh-" Casually taking off the black iron badge, Ye Yu gasped and said softly: "Let's go." ”

Tick, tick.

The passage was quiet, deathly, with the occasional sound of water dripping, the footsteps of several people, and even the sound of leisurely breathing.

Unconsciously, the three of them felt a depressing atmosphere permeating, as if they were about to force people to breathe.

Suddenly, Ye Yu suddenly found a pair of blood-red eyes on the top of his head not far away, and then he also found countless blood-red eyes behind him.

"Hula. ”

"Flutter flutter. ”

A palm-sized bat fluttered its wings as if it had begun, and then countless small bats flapped their wings and pounced violently from the dark passage.

"Ahh The pale blue knife danced instantly, like the bright moonlight in the dark night, dispelling all darkness.

Bang bang bang.

It was raining, and countless bat carcasses fell overhead. Like chopping melons and vegetables, under the protection of the pale blue knife, Ye Yu and them are like reefs in the tide, standing still.

After all the bats flew away, Ye Yu breathed a sigh of relief and said, "Huh, I didn't expect there to be such a group of bats here." ”

You Lan didn't answer, but slowly raised the Oriental Blade in her hand, the blade only pointing to the front of the dark passage, with a hint of vigilance in her eyes.

Seeing Youlan's look as if she was facing a great enemy, Ye Yu and Fei Ye instantly understood something, Fei Ye activated her [Archer Bow], and Ye Yu tightly held a card.

The eyes of the three people were firmly fixed on the depths of the dark passage......
