A hill, inside a hill, a cave.

No wind, no stars, no moonlight.

The thumb-sized crystal shimmered in Ye Feng's hand, looking extremely dazzling, reflecting the entire cave.

Brighter than the flames, but not hot, but cold.

"That's why I spent so much time in the pothole, this thing, it's interesting. Ye Feng suddenly smiled.

His eyes were like stars, and when he smiled, he shone brightly, like a wolf in the middle of the night, and he looked at the crow.

The black crow and the others looked puzzled.

"Did you know that you were almost discovered by the group of skeleton soldiers just now, and now you have alarmed the skeleton soldiers, and they are searching for them with all their might. Wu Xie frowned slightly.

"It's okay, it's okay to get this thing, it's okay to take some risks. ”

Ye Feng didn't have much to worry about.

"By the way, Big Brother Crow, you have a good look. ”

After Ye Feng finished speaking, he slammed the thumb-sized crystal into his arm, and blood burst out.

As soon as the crystal touched the blood, it immediately melted into Ye Feng's arm like a drop of water.

Suddenly, Ye Feng's body slowly became illusory, and then disappeared.

"What's going on?" The hundred and ten people in the cave were extremely surprised, they looked towards the cave, and they couldn't find any breath from Ye Feng.

Ye Feng seemed to have disappeared from this world.

The crow's eyes sparkled, and he suddenly understood something.

A wicked smile appeared at the corner of Wu Xie's mouth, "Ye Feng, I finally know the reason why you stayed in the pit." ”

As soon as Wu Xie's words fell, Ye Feng's figure reappeared, and a heavy smile still appeared on his face.

"That's right, that's why the skeleton soldier can be stealth, I was puzzled before, why the skeleton soldier can be invisible, so I tried it, but I found that there was a very strange thing in their bone marrow, so I extracted it, it was this crystal. ”

Ye Feng's palm was floating with spiritual qi, and then the thumb-sized crystal just now appeared again.

"This thing can hide all the cultivation and aura on their bodies, so this is the secret of the hermit skeleton soldiers. ”

On one side, Xiao Huang was at the entrance of the cave, staring outside, motionless, as if an old monk had settled down.

"We've studied skeleton soldiers before, but we've never discovered the secret of this hermit skeleton soldier, Mu Feng, how did you find out?" asked Black Bull with a puzzled expression.

And the others also looked at Ye Feng with this expression, with a strange expression.

As for the black crow, he looked at Ye Feng with dead eyes, hoping that Ye Feng would give them a satisfactory answer.

"Well, it's mainly me as a monkey, I'm a monkey, you should find something unusual in him, this thing is very sensitive to souls and things like that. ”

Of course, Ye Feng wouldn't say that this crystal was something he got by absorbing the skeleton bone marrow through the Northern Pluto Divine Skill, so he could only come over to cushion his back.

Xiao Huang was still outside the cave, but everyone's eyes suddenly shifted from Ye Feng to Xiao Huang.

"Your pet is indeed very evil, from it, we can feel the threat, the threat from the depths of the soul, and along the way, this monkey is excited when he sees something like a soul, if this is the case, it is easy to understand. ”

The black crow looked at Xiao Huang outside the cave, Zhuge Jinxiu told himself that this monkey beside Ye Feng was very evil, and he must not annoy it, although he didn't know why Zhuge Jinxiu would say this to himself, but from Xiao Huang, the black crow did feel a trace of throbbing from the soul.

"I didn't expect this monkey to be so powerful, wouldn't it have helped us a lot?" The black bull opened his mouth and smiled happily, but he looked a little silly.

Wu Xie looked at the black bull on the side, this big black man is just a fool, he is a hanger when he laughs and cries.

If you have the chance, you must have killed him, in Liancheng, this guy has bullied himself a lot, you bullied me, I remember it, and I must settle accounts with you one by one.

Wu Xie's thoughts, no one could understand, and no one paid attention to them, they were all attracted by Ye Feng at this time.

"Since let my monkey discover this secret, then I have a plan, if we get all a hundred people to get this crystal and put it on us, we are an elusive killer, and we can definitely disrupt the plans and pace of the hermit skeleton soldiers, so that for the battle in the base camp, it will definitely be beneficial and harmless. Ye Feng's eyes flashed with a glimmer of light, and he was extremely excited.

"Ye Feng, okay, I agree with this plan, I didn't expect you to bring us such a big benefit the first time you came here, it's just a stroke of genius. After hearing Ye Feng's plan, the black crow thought about it for a while and felt that this plan could definitely be implemented.

slapped his thigh suddenly and gave Ye Feng a thumbs up.

The others also looked at Ye Feng very excitedly, because once this plan succeeded, it would not only be able to reduce the casualties of this hundred people, but also better contain this group

"Since, Brother Crow, you agree with my plan, let's hurry up and carry out the plan, but the most important thing now is to find the skeleton soldiers, kill them, and seize the bone marrow crystals in their bodies. ”

Ye Feng's eyes narrowed and he looked at the black crow.

"Don't worry, let's take action, although they have already noticed it, but with Wu Xie here, we are still very easy to do, besides, don't you have a crystal now, give me this crystal first, you stay here, I will go out with Wu Xie, and kill the skeleton soldiers first." ”

After the crow finished speaking, Ye Feng did not delay, and directly forced the crystal in his body out.

The black crow's cultivation is the highest among all the people present, he is in the early stage of the cave void, with his shot, it will definitely be easy to deal with those skeleton soldiers, even if he can't destroy so many at once, but he can always hunt a small part.

After distributing these crystals to the soldiers, the soldiers can go out to fight together until they find all the crystals needed by a hundred people, and then this vanguard can be like a sharp sword, inserting into the army of skeletons and disturbing the opponent invisibly.

......

In a blink of an eye, three days passed in the blink of an eye.

It's still the same cave before, and at this time, a hundred people have all the crystals in their hands.

However, in the course of these days, Ye Feng also discovered some secrets, or problems, about the crystal.

Once the crystal leaves the human body for three hours, it will disappear without a trace, turning into nothingness.

"Within a thousand meters ahead, there is a hermit skeleton soldier, they are marching in the direction of Liancheng, should we kill them?" Wu Xie as a scout, his nose is extremely magical, just like a sudden pat of his nose, you can find the traces of the skeleton soldier.

"Of course we want to kill them, we must make them mess up, right, Brother Crow!" Ye Feng grinned, Xiao Huang, standing on his shoulder, also looked impatient, extremely excited.

"Of course, what Brother Mu Feng said makes sense, we are going to kill them, and now we are invisible killers. The black crow laughed, let out a long whistle, and waved his hands, so the group of people immediately disappeared and disappeared in an instant.

There was only a strong wind and footprints left on the ground, but the wind in this Tempest Mountain Range was extremely violent and dusty, and soon the footprints disappeared.

A thousand meters away, a group of more than 100 skeleton soldiers, riding fiery red bone horses, galloped through, their direction was the north gate of Liancheng, where the defense was the weakest, because the north gate mountain range was towering, easy to defend and difficult to attack.

Relying on natural hazards, the soldiers on defense are not so nervous.

The speed of movement was very fast, and wherever they passed, the ground immediately burst into flames, and the flames soared into the sky.

In the blink of an eye, the flames were extinguished as soon as they were gone.

The ground was scorched and blackened with traces of flames.

Suddenly, before they moved, the ground collapsed.

There was a sinkhole more than ten meters long, which looked like a cliff.

Shout......

A bony horse let out a long roar, and the skeleton soldier sitting on the horse grabbed the reins and reined in the precipice.

At the same time, a sword net appeared in the sky.

The black sword nets, more numerous than the stars, were intertwined, and suddenly fell from the sky, completely surrounding more than a hundred skeleton soldiers.

Chirp, a huge crow more than ten meters long and wide, black, the size of most of a sword net, suddenly burst out from the edge of the cliff of the pit.

Directly opened his mouth and swallowed the more than ten soldiers closest to the cliff, the soldiers with bone horses, people and horses.

Ka Cha Ka Cha, Bone Horse and Skeleton Soldier, before they could attack, were chewed to pieces.

"Xiao Huang, let's kill them without leaving a piece of armor, so many soul fires, see if you can endure it. ”

As soon as the hundred ghost flags in his hand came out, Ye Feng's entire body was shrouded in layers of black qi, and the black qi covered the sky and the sun.

From the edge of the cliff, it also emerged, like a gust of wind, swept by.

Whoa.

Inside the Hundred Ghost Banners, hundreds of ghosts rushed towards the skeleton soldiers with their teeth and claws.

The skeletons suddenly encountered the enemy, and they lost dozens of skeletons in a lightning speed, but they reacted quickly.

Standing in the center, a skeleton soldier in the late Yuan Infant period, shouted loudly and became invisible.

The group of skeleton soldiers disappeared out of nowhere, but the fiery red bone horses they sat on did not disappear with them.

A wicked smile appeared at the corner of Ye Feng's mouth.

"It seems that this group of skeleton soldiers didn't get the news that we have found their secret, haha, Xiao Huang, now, we can do it. ”

In Ye Feng's eyes, the skeleton soldiers who were hidden just now could still be seen.

Because these people also have invisible crystals in their bodies.

This is another secret of the crystal he discovered.

"How can this be?" When the stealthy skeleton soldiers were about to go on a killing spree, they found that a group of human ghost cultivators in black robes and battle armor on the opposite side ignored their stealth at all.

"No way, how can they be invisible???"

The skeleton soldier in the lead looked surprised, completely unconvinced. The soldiers behind him were also stunned.

But the killing doesn't stop because they're stunned.
