Fang Yuchen grabbed the protruding rock with his hand, shook it hard, tried the firmness there, and then climbed up with a turn over.

On the steep slope is the source of an underground stream. The cold stream water flows out from the darkness and gurgles. The stream water is covered with fluorescent moss, plump and green, and a little burnt yellow. With a press of your hand, some insects living in the dark crawl out from under the lichens.

Most people may feel their scalp numb, but Fang Zhu learned this, so it is not surprising that he is common. Those bugs are common categories, living in a dull environment, a kind of larvae of a cave beetle.

This insect lives deep underground in Etaria, which may even be close to the "cavity rock formation", which is a geological hypothesis that the air and land in Etaria is not solid, but there is a crisscrossing hollow world deep underground.

There is a Guy crystal source that is enough to support the entire floating continent, which is called the "Great Crystal Veins". Some Guy crystal sources may even last thousands of miles. In the 1064th year of the Esolin Calendar, people have actually discovered the surface of this rock formation world, in the pillars of stars in Rotao.

Subsequently, the underground world was discovered by people, and this hypothesis became a real theory. However, the "cave rock strata" of different floating continents are all connected to the soil element layer. There are elemental creatures that don't like outsiders. There are some other difficulties, which have led to no one who can thoroughly investigate these underground worlds.

Fang Zhu was not the first person to penetrate deep into this rock formation world. As early as seven years ago, a Dwarf Association expedition team funded by the Cast Iron Hall went deep into the underground. The mountain dwarfs were most familiar with the underground world, where they were like returning home.

That expedition ran through the entire underground rock formation world of Elderon, and for the first time people discovered a branch of the legendary "Great Crystal Vein" underground.

Since the star gate opened, this magical world has gradually revealed its mind to people. Explorers from different worlds have pushed open doors to see the reality of this world. Now, their steps are no longer limited to this old world.

A voice came from behind him. He looked back and saw Miss Mayi climbing up from there with a shield on her back, and a long war halberd hung behind her, but Miss Knight was not clumsy at all. Fang Zhu stretched out his hand, took the other party's hand, and pulled Mey up from below.

"Mr. Ed, your hands?" May looked at the red blood stains on Fang Zhu's magic gloves and asked with some concern.

Fang Zhu shook his gloves and didn't care much, "Don't worry, it's just a fluorescent substance on lichens, a mineral. Dragon Blood Moss likes to draw this mineral from rocks, and hence the name."

He had a headache about how to clean it. This thing is natural mineral dye and is quite difficult to clean. If he had known it, he wouldn't touch those mosses, or if he was wearing the pride of the Lone King, he wouldn't be afraid of dyeing the metal.

Now everyone takes turns to clean clothes on the boat, only he and Silvede's clothes were done by the maid. Miss Xieshita would probably roll his eyes.

"This place is mostly the hollow layer where the 'Great Crystal Vein' is." Fang Zhu looked up at this place, and after coming up from the narrow tunnel opened by the Elemental Monarch, he arrived at this underground world.

The underground world is dark and empty tunnels, but some scenery is magnificent. They walked along the way and saw many magnificent wonders. The interlaced hollow layers intersected with each other and hung upside down in the air.

Fang Yu retreated his gaze, "The surface of the great crystal vein is usually one thousand meters underground. I don't know how deep we are, but the elemental monarch named Alphons asked us to leave. This road can most likely lead to the surface of the earth, but I don't know how long it will take to go."

He couldn't help but feel a little grateful that the original foresight had prepared extra rations before he came down, otherwise he and Miss May might have starved to death below before they even walked out.

The Elemental Monarch probably cannot understand the biological needs of mortals, so it is impossible to prepare food for them.

May looked quiet, and only looked up at the strange underground world, blinking his eyes lightly.

In fact, it is not that the food source cannot be found in the underground world. Although most of the tall mushrooms are poisonous, a large part of the insects that feed on them can be enjoyed.

But no matter how familiar he is with these things, he cannot overcome his psychological discomfort. After all, it is not that he has no choice. He would rather choose to resurrect in a certain temple than he would.

As for May, Fang Ling knew that she was terrible and she said in person that she had eaten insects more than once during the training of the ancient knights. "The roasted insects actually have no taste and tastes very tiring," Miss Knight shared her experience with others seriously. "As for eating raw, it is mostly the taste of the contents in their bodies, mostly astringent and bitter."

Except for the box being a little interested in this, most people in the group were embarrassed about it.

Fang Zhu shook his head and threw these meaningless memories out of his mind.

Because they used a lot of physical strength to climb up the cliff, the two of them rested by the stream for a while before continuing to move forward. On the way, the pulp tore some dry lichens in their pockets, because they didn't know when they would stop and camp. These things were just right to attract fire.

He mostly learned his survival skills in the wild at the Star of Dawn, and later he was on the way to adventure and never missed it.

The two of them were picking up lichens while moving forward, but after a while, May suddenly let out a 'huh' sound. She stopped and stared at the spectacular miracle in front of her. There was a cliff in front of it, which was actually the exit of a long cave.

Fang Yu couldn't help but put down the lichen in his hand and also stared at the scene in front of him. The canyon was like a knife, deep and unseen. The huge crystal veins spreading there exuded bright light, like a river of light, winding to the end of his vision.

Great crystal vein.

Although Fang Yu had heard of this for a long time, he was still shocked at this moment. He had seen the huge elemental monarch as mountains, but it seemed almost small under this scene.

In front of such a great existence, mortals are like dust to the vast sea, like sand to the stars.

His chest slumped, as if there was a roaring sound inside, but the sound came from the bottom of the abyss, the sound of the earth, and the sound of the long river of Ether passed through the crystal veins of Sinta'an.

Rumble, surging.

A huge lightning was passing through the crystal groups, spreading several kilometers before it was another, and the magic turned into a flash, almost substantial. If the floating continent had a heart, then this was its blood vessel.

Sintaan is worthy of the name of the sun's giant. It is the most complete and oldest of all existing floating continents. It is the place where God is watching, just like a giant god who sleeps here forever.

Standing for a long time before this canyon, Fang Zhu almost felt that he was about to be assimilated by it, and his will and blood were integrated. He took a step forward, and then he was shocked and hurriedly took back his steps.

Then he turned his eyes away from looking at the wonder scene. It was not because his mind was attracted by it, but because of the resonance of magic. Although mortals have weak perceptions of elements, they are still part of this world after all.

"What a pure ether," May also took a step back and sighed. She stopped looking at the huge crystals. "Mr. Ed, what is this?"

"Great crystal vein, but this place is far from the source of ether." Fang Yu looked at the environment here, and suddenly thought of something. He turned around and took off his backpack and placed it on the ground.

He took out several instruments from his opened backpack and said, "I have read the documentary records of the Geographical Association of Cast Iron Hall. The crystal veins underground in Elderon are more spectacular than here. This should be just a branch of the great crystal veins. The good news is that we should not be more than one kilometer from the ground..."

May listened quietly to his description, but did not interrupt.

Fang Yu talked about it a bit endlessly, "The ubiquitous Ether Sea of ​​Aitalia formed a river of light on it. Several of them passed through these crystal veins to form these huge Guy crystals, thereby supporting the floating continent. The deepest of these crystal veins will extend to the deep center of the earth and merge into the elemental realm there."

"It has been hundreds of years since the mortal world developed the Guy Crystal, but it has never really involved great crystal veins. Many Guy Crystal veins in the surface world tend to be exhausted, so some people have put their abacus on this place. After all, if mortals can use the great crystal veins, Guy Crystal may be inexhaustible."

May then spoke, "But why did Maye never hear about it?"

"Because no one has succeeded," Fang Rong replied, "It is a very costly thing to go deep into the hollow world, let alone mining. What's more, we can stand here and get Alphonse's approval. Don't forget that this is actually the home of earth elements."

If you want to force yourself to go deep underground, just think about the Aoshu people outside and you will understand.

But May suddenly thought of the huge equipment of the gray underground imperial people.

"The Empire came for this, too?"

Fang Zhu nodded, "Yes, those are the past tense. Now the Empire may have been half successful."

"Mr. Ed, half of it?" May asked, "Are the Ossey pulling the power of the underground Guy Crystal Vein?"

"Take it?" Fang Yu shook his head, "I'm afraid it's not, but I already have some guesses." He said, while rummaging through the backpack and finally finding what he wanted from it.

It was an instrument, and it looked like a vertical magic furnace.

The square purse took it out of the backpack, and there was a tripod under it. The square purse supported it and fixed it on a solid rock layer. Then it was equipped with a crystal brazing, about one arm long and connected to a metal rod.

The metal rod is composed of three iron tubes. Square plucks tighten them one by one and combine them together, then stand up, raise your hands and insert the crystal brazing downwards and forcefully into the solid rock formation.

There was also a copper cable on it, and he connected the other end to the small instrument. This set of instruments is very valuable, and it is definitely impossible to afford it in terms of Fang Yu's wealth. This is the set Bai Jia lent him to survey crystal readings.

To be precise, it belongs to the military—

He has to return it after using it.

A clattering reading came from the magic furnace. He covered the magic gloves on its interface. Originally, Su Changfeng asked him to use this instrument on the crystal tower, but the crystal tower was deep into the Ethernet vein, but what else is there in Aitalia closer to the etheric source than here?

Fang Yu closed his eyes. He had been trying to verify that point since he went deep into the ground, but at this moment, it happened to be the most suitable time. But just as he closed his eyes, he suddenly heard a slight sound coming from behind him, and a muffled groan of May.

Fang Yu was alert and was about to turn around, but a cold touch came from his neck, and a sword blade was already pressing there. He looked back, and then Mayi covered his arms and retreated aside, with the long halberd and the big shield falling aside.

A tall, silver-gray humanoid structure blocked her and the attacker, who was holding a cage-handled sword around his neck.

And Fang Yu actually knew that person.

It was the Prometheus dragon knight he had once dealt with in Istaña. Fang Zhu remembered that the other party was called Irs, and it sounded like a code name or ID.

It is hard to have any friendship with him as an enemy but not a friend. At the time, in the consciousness space of the Blind Eye God, he and Miss Tata teamed up to teach the other party a lesson. Afterwards, the man disappeared, but he didn't expect to meet him here.

"Mr. Ed, be careful..."

Miss Knight frowned and looked at the person, obviously judging by the opponent's strength.

But Fang Yu seemed calm, as if he was not facing an opponent from that level, but just an acquaintance who had met once, and this was not a space of consciousness.

This chapter is not over, please click on the next page to continue reading! He only looked at the other person's expression, looking like he was crying but not laughing, and was speaking to him in a hoarse voice: "...I didn't expect that she was indeed with you. I was a little suspicious..."

"You mean," Fang Zhuan asked, "Margaret, the Dragon Queen?"

"Who else except her..." Irs didn't know what he had experienced in the past six months, but he looked like he was in a daze. "The daughter of Livgard, the Dragon of the Origin, the second dark dragon king... I shouldn't have let you go in Istaniya..."

May looked at Irs quietly. She had seen Alessa and naturally knew her identity. However, she joined the team after the completion of the Qihai Traveler, and officially boarded the ship after the Northern War.

She has heard of the incidents between Istaniya and the evil god, but she has not experienced them personally after all.

So she just listened to the conversation between the two carefully.

Fang Zhu directly interrupted Irs' words, as if there was nothing Prometheus's dragon knight in front of him: "It's hard to say who released him in the Silver Swift Sea. I think you must not have had a good time at that time, but it's a pity that you didn't throw you into the prison of the Kingdom of Sands... What you did in the Sea of ​​Sands was far away from the criteria that the candidates should have."

Irs chuckled twice in a hoarse voice, "But I am the caller, and the laws of the natives cannot judge me."

"That's just the usual situation," Mey said, "but it's not within this that you are engaged in terrorist activities, joining cults, destroying Star Gate, subverting the country, and killing the indigenous peoples. What you do in Istaniya, Mey has heard of, it's horrifying and outrageous."

Irs glanced at the two of them, "Okay, but most of them are... what the Empire does, I am just an executor, and I was not involved in it, I only attacked you in the end. Many things in Istaniya happened more than ten years ago, and you should be able to see... More than ten years ago I was just an insignificant unknown lord..."

He suddenly realized something and waved his hand with some anger, "What do I explain to you? Now the initiative is in my hands. Listen, you'd better act according to your order."

"I'm afraid it won't work." Fang Yu refused directly, and looked at the sword blade in the other party's hand as if nothing had happened.

"What? Are you not afraid of me killing you?"

"Not mentioning what if I kill me, I'd be afraid that we wouldn't have entered the consciousness space of the evil god at that time, the situation at that time was no thousand times more dangerous than at this moment," Fang Yu looked straight into the other party's eyes and replied, "And, are you really going to kill us? But I didn't feel the murderous intention from your sword."

"Killing intention?"

Irs was stunned for a moment. Can the illusory thing like murderous intent be felt? He couldn't help but glance at Fang Yu in a strange way, thinking that this guy was a little bit too hard.

But Fang Yu's confidence comes from his own dark blessings. The prediction of death can allow him to completely avoid the opponent's attack once a day, whether the opponent is a mortal or a god. But that omen has no movement at all, which only means that Irs did not come for him when he set out his sword.

This is just evidence.

Fang Zhu looked at the Prometheus's dragon knight in front of him. Of course he was not a fool. The Seven Seas Brigade had investigated Prometheus in detail before heading to the empire. After all, no one wanted to bump into a hostile dragon knight head-on.

But judging from the news I received, it seems a bit strange. If the rumors are true, since Irs returned to Prometheus, it has been widely rumored that he has become a bit weird. Not only do he often stay away from home, but he also imposes great restrictions on Prometheus' members.
