The roar in the purple mist shook through the engineering room, swaying up along the smashed crack, and the roar shook the sky. Green turned around abruptly, staring at the black figure in the purple mist, and subconsciously shuddered.

The voice sounded familiar, and Green held on to the slate, almost throwing his hand back into Blake's lap.

Corrosive, dragon-like, pig-like, purple mist......

He furrowed his brow, the hints rushing through his mind, and with even a flash of inspiration, he might have to remember what was in the mist.

"Green!"

The dark elf, who had been pounced on by Green, suddenly rushed up and waved his hand with a knife. But Green didn't dodge, and although Miree had a cold personality, she was not ungrateful, so when he looked up, he saw the short blade in the female assassin's hand slashing at another falling rock, and the strong pressure instantly bent the blade.

But she had already bought enough time, and the reacting boy raised his hand and stabbed through the falling stone from the very center, and the flame dragon burst out and immediately scattered all over the ground.

"Thank you." Grimm thanked him sincerely, only to be surprised to see Mirei skimming her head. If it was usual, this indifferent dark elf rarely showed a shy appearance, and Green would definitely have to take a good look, but at this time he didn't have so much leisure.

Removing the slate, he could clearly see the injury on Blake's leg, which had to be treated immediately.

"Mirey, come and help."

Green had a commanding tone, which made the dark elves a little angry. But she also confirmed that Grimm had a good heart, otherwise she wouldn't have saved the strange self and this human. She hesitated for a moment, not mentioning the destruction of the Ancestor's building, but finally chose to help Green take Blake by the arm and lead him all the way to the wall of the engineering room.

"Thank you, young man." Blake took a breath, tore open his clothes and bandaged his wounds, and thanked him, but as soon as he raised his head, he saw the cold face of the female dark elf, and he was stunned for a moment and then smiled bitterly.

But when he thought about it, he was even more grateful to Green.

"May I ask you ......" "Get down!"

The bearded Blake had just finished halfway through his words, when Green, who was looking back as he walked, was suddenly startled, and pressed down Blake and Milley with all his might.

Purple blades of wind with blade-like pressure shot out of the mist, and one of them suddenly swept across the backs of the three of them, smashing into the walls of the dark elves with a snorting sound, like hot water pouring ice into it, stirring up thick white smoke. When the smoke and dust cleared, the three of them looked up sharply, and were stunned to find that the indestructible stone wall had actually left traces of corrosion up to half a meter deep.

Corrosive - or poisonous!

"You're aiming for this thing?"

Green asked incredulously, pointing to the monster behind him that was starting to get restless.

The bearded man gasped for breath and shook his head without hesitation: "No! The Roaring Mist Lands were indeed their map targets, but the obvious evil was a far cry from the image of the relics he had made his journey.

Green breathed a sigh of relief, if he faced such a monster and then went to war with the Hidden Bone Gang at the same time, he would really have to consider a strategic shift, "It seems that I won't be an obstacle to you - call me Grimm." He quickly got to his feet and pulled Blake by the arm with Millet and retreated into the corner.

Green's tone made Blake a little curious, "Do you know who I am?" ”

"I don't know, but I know you're a group of bones." He pointed to Blake's shoulder armor, which was very clearly marked with the skull of the Bone Group.

Blake showed a sudden expression, "Mr. Green is well-informed, it is really rare at this age. He remembered Green's previous superb swordsmanship, which looked like a swordsman who had been immersed in kendo for decades, but had only just honed his skills and strength, although it was strange, but Blake had not seen anyone with the most talent, so he added, "Your swordsmanship is just as amazing." ”

Green nodded, not overly proud of Blake's admiration, even if it was the supreme honor of any soldier to be praised by the military commander of the Hidden Bone Clan.

The three of them managed to retreat to the wall, and Green found a place where the rocks had collapsed to settle Blake. He turned his head, his gaze falling on the black-purple mist. At this time, the "filthy thing" spun faster and faster, almost like a small tornado, but Green knew very well that the black shadow inside was the main body, and this was just a precursor to its burst. Only this time, when Green's eyes intersected with the black shadow, a deep light suddenly shone directly in front of him, and a hideous meaning was choked in his throat.

Green's eyes widened suddenly.

"Sir!"

Not far away, there was the shouting of soldiers, and the non-commissioned officer captain who had been following Blake fell to the other side, and at this moment he had gathered several soldiers of the Hidden Bone Group and ran in the direction of Blake. The beard gestured back, signaling that he was not threatened in any way and that he did not need to remain hostile.

Mi Lei snorted, she didn't have the slightest affection for these intruders. She turned her head away from looking at the silver armor, but suddenly found Green's unnaturally distorted face, and couldn't help but be startled, "Green! ”

The boy turned his head a little mechanically, his godless eyes met the dark elf, and in the darkness, an invisible flame suddenly flashed on his forehead.

"It turned out to be your ......"

The glow returned to Green's eyes. It was as if he had gone through a big battle, and he was drenched in sweat, but there was a look of clarity on his face, just panting, which inevitably attracted Blake's attention, "Mr. Green?" ”

Green leaned on his knees, letting beads of sweat run down his sideburns. His expression was surprisingly revealing of unspeakable confidence, and he looked up in the direction of the mist.

The greatest fear of human beings lies in the uneasiness of the unknown. Once you know what you're up against, it's not so scary.

What's more, this is still an "old friend".

"I—I know...... What's that......"

Compared with Blake, who doesn't know why, the female dark elf is obviously more concerned, but before her words can be asked, the situation on the field has changed suddenly!

In a few sentences, the non-commissioned officer captain had already walked over with the team. The purple-black mist that swirled into the air was behind them, perhaps in the eyes of the non-commissioned officer captain, it was just some kind of dangerous dark elf magic device, and the safety of the beard was the first priority, so he didn't pay attention to the mist. But when the soldiers of the Hidden Bone Group gathered their ranks, that obvious threat suddenly made the monsters who were committed to it fierce. It didn't hide anymore, and the wind and tide collapsed, and the aura like smoke and fog instantly enveloped the few soldiers at the back.

"Something!"

The whistling finally alarmed the captain, but when he turned around and raised his two-handed greatsword, it was too late to take precautions.

The power of the black shadow broke away, pushing the black-purple smoke to radiate in all directions, and the soldiers of the Tibetan Bone Group who fell at the end were entangled in the breath before they even had time to react, and let out a suffocating "ho, ho" sound in horror, and in a few seconds, the whole person was eroded to a thousand holes, and even the iron sword on his body was corroded, leaving only the white bones and a sticky lump of tissue.

"Don't touch it! Get down! ”

Seeing that the non-commissioned officer captain was subconsciously about to swing his sword, Green hurriedly shouted. Out of inexplicable trust in him, Blake also hurriedly shouted, "Everyone get down!" ”

The sound of the beard finally made the soldiers of the Tibetan Bone Group who had ordered the ban to react, including the non-commissioned officer captain, no one raised any objections, even the soldiers who had already swung their swords halfway, regardless of the risk of spraining their wrists, forced themselves to fall to the ground.

He did hurt his wrist, but he saved his life.

The purple gas emitted was extremely fast, but it only floated in one layer, and after the soldiers lay on the ground, the three Grimm also quickly crouched down. Looking at the engineering room that had been slashed and devastated before, and now it was as if it had been scalded by a ring soldering iron, everyone shuddered.

"Thank you, Mr. Green." Blake stood up with the help of the stone, and saw that the non-commissioned officer captain and some of the soldiers behind him were safe and sound, and once again thanked him heartily. But Green didn't say anything unkind, this time he wasn't a good man for free.

"Bone Swordsman Legion, Silver Bone Formation?"

He looked at the uniform of the captain of the non-commissioned officer and recognized it at a glance by the light from the hole above.

Blake's breathing slowed a beat. He took a deep look at the young man beside him, then nodded, "It seems that Mr. Green is more than just knowledgeable. ”

Green shrugged, "Understand." ”

At this time, some of the soldiers of the Tibetan Bone Group in front of them got up and looked back, and immediately exclaimed, "What is that!?" This shout immediately attracted everyone's attention.

The huge black shadow has revealed its fierce face at this moment, its eyes slightly closed and its head bowed to the ground, more like the accumulated strength before the rise than surrender. It looked bloated like a giant boar, and occasionally exhaled foul gases into the air above. But the two strangely shaped horns on its forehead stretched out to its spiky back, and the two corrupt wings seemed to be hollowed out, which seemed to add an extra domineering spirit that belonged only to the proud race.

"Undead Dragon?"

Blake looked at the huge black shadow and muttered to himself in confusion.

"Nope." Green took a deep breath. He stared at the black shadow, holding the Flame Shadow Sword in his hand, his mood was complicated and a little excited, "Mr. Black, no matter what your goal is this time, I think it will be related to the Fountain of Youth in the end, right?" ”

This time Blake was not too surprised, since he knew the reputation of the Hidden Bone Group, he naturally would not be unaware of their core purpose, so he nodded, "Exactly." ”

"I don't have any interest in the Fountain of Youth, you don't need to worry about me, I'm afraid I'm here for the reason I'm going to be the enemy of all of us soon." He raised his Flame Shadow Sword and pointed it at the huge black shadow that was prostrate on the ground, "So, Mr. Black, can you lend me your power for the time being?" ”

He looked at the stunned non-commissioned officer captain, then looked at Black, "It's just this battle, Mr. Black, can you give me the command of this squad?" ”

The bearded man motioned to the captain with his eyes to calm down, and then looked at Green with a stern expression.

He and Green looked at each other, as if trying to see his intentions in the boy's eyes, "We are first acquaintances, Mr. Green, although you have saved my old life, but one yard is one yard, and I can't promise you lightly - but maybe you can give me an answer, Mr. Green, you seem to know what it is, can you sue me?" ”

At the sound of the monster's heavy breathing, everyone fell silent and looked at the young man standing with his sword raised.

Green nodded, then replied in a clear voice, "It's a phantom creature." ”

Hearing this answer, everyone was stunned. The so-called phantom creatures are generally some kind of creatures with real identities, which are divided by the body of great strength, or the energy separation caused by the effect of force majeure factors, and finally form a creature similar to a clone. This creature has some of the characteristics of the ontology and even some of the memories, but compared to the real body, most of the strength declines, and even weakens over time and finally fades to nothing. Under normal circumstances, if a level 100 B-rated monster produced an illusion, the situation in its heyday was only a level 60 D-rated strength, so as soon as Green's voice fell, the non-commissioned officer captain immediately raised a voice of opposition.

"If it's just a phantom creature, we don't need your help at all, and the strength of our Hidden Bone Group is enough to solve it! My lord, please give me orders. ”

The captain's voice sounded confident, but Blake was not blindly optimistic, he looked at Green's solemn expression, and knew that it would not be so simple.

"Perhaps." Green nodded casually, and he walked forward step by step around the rocks, meeting the unkind gaze of the non-commissioned captain, walked up to them, raised his head, and met the two dim rays of light.

Those are the eyes of "filthy things."

"I wouldn't have believed we'd meet again if I hadn't seen it with my own eyes, but rest assured, I won't treat you with the slightest scorn like an idiot, no matter what." Green's words weren't too loud for the monster, but they were clear to everyone's ears. The non-commissioned officer captain's face suddenly darkened when he heard this, and the pride of the silver-bone swordsman swordsman made him unable to tolerate any insults from others, and he was about to attack when he pressed the hilt of the two-handed big sword, but he heard Green's fluttering question.

"I mean, you've been awake since someone stepped into the underground drain, haven't you? So far, you don't plan to do it, could it be that you want to wait for me to get closer to you? ”

The young man's voice paused slightly, and he grasped a qiē confidence back into his chest, and his tone was actually a little bantering.

"- Then I'd be an idiot. Oh, by the way, Mr. Captain, you say 'just phantom creatures'? I don't know if you've ever heard the name 'Plague of Erosion', but in my opinion, it's another more colloquial term. ”

As he spoke, the flame shadow in Green's hand flashed, and the flames swept the blade of the sword, falling with him with a word, catching up with the monster that suddenly spewed out a large number of black spots.

"Vanguard of Chaos - Fourth Apostle Nidhogg."

(P.S.'s recently bookmarked...... It's very rhythmic, lingering for several days, and finally at the urging of Maruko, I decided to ask everyone, does anyone know what's going on? ）
