Crystal skeletons.

After Lu Sheng learned about this strange thing from his father Pang Yuanjun, he immediately made all preparations to go to the Gray Realm.

If at the beginning, he had a certain exploration mentality that he could go or not, then after learning about the crystal skeleton, he was much more interested in the gray world. In addition, the gray world actually has a time flow speed difference, which makes him have subtle doubts about whether the gray world belongs to this world.

In his many experiences of coming to the other world, only different worlds and different time and space will have this abnormal time flow rate.

Time and space, in the normal universe, often coexist in harmony. Changes in space can also cause time to distort.

After more than three days of preparation, in order to prevent the closure of the Gray Realm, Lu Sheng once again went deep into the ruin cave recorded by the Half-Demon Organization, and went to the Gray Realm for the second time.

Call!!

Jumping down from the cave exit for the second time, Lu Sheng looked into the distance in mid-air.

Before entering the waterhole, there are large expanses of plains around it, which also seem to be less of this world, but more like a transitional environment.

If he didn't have enough time, he would have wanted to explore the world around the plain first.

Boom!!

The body smashed into the icy biting water, and Lu Sheng's whole body released a hot scorching breath, which was the terrifying heat that the incomparably powerful heart naturally emitted with the heartbeat after being promoted to the Martial Emperor.

Now, if he doesn't deliberately restrain himself, he is simply a fierce monster that exudes a huge amount of qi and blood heat.

This is the supreme realm of the Martial Emperor of this world.

Not only would he exude this terrifying aura, but he would also be able to manipulate the hot air flowing from his pores.

In the gurgling bubbles, Lu Sheng quickly swam back into the underwater honeycomb channel.

After swimming all the way down the passage, after a few minutes, he sped up sharply.

Soon, there was a sound of water, and he jumped up from the waterhole, lightly stepped on the water for a few steps, and landed on the edge of the waterhole with the help of his strength.

"It's still the same..."Lu Sheng looked left and right, and found nothing, except for white bones or white bones.

The biting cold wind continued to pour in from the surroundings, and there was no breath of the living in the wind.

Lu Sheng's body was hot, and quickly a large area of white water vapor steamed up on his clothes.

After steaming his clothes, he did not rush in the previous direction, but followed another direction, running with all his might at will.

The sound of heavy footsteps continued to smash terrifying pits with exaggerated diameters on the ground.

Lu Sheng was wearing a hard cloak that was specially prepared this time, and after jumping up, he grabbed the edge of the cloak, and the person could fly forward as quickly as a glider.

This is a simple piece of equipment made by Lu Sheng recalling the principle of the Earth glider.

It saved him a lot of effort.

After sprinting for about hundreds of kilometers at full speed, the sea of bones, which has been monotonous and boring, finally has a new change.

A large gray whirlwind, I don't know when it began to fill the surrounding sky.

As soon as Lu Sheng entered this whirlwind, he immediately felt that there was a subtle hallucinogenic poisonous powder mixed in with it.

"Poisonous winds?" he involuntarily sped up, and it took him more than half an hour to pass through the gray air current.

After a boring journey for more than an hour, Lu Sheng planned to see nothing of value again, so he was ready to set up a magic circle and return to the Heavenly Demon Realm.

Staying here is undoubtedly a waste of time.

Burst!

Suddenly, there was a faint popping sound in the distance from the large pile of bones, which sounded like a heavy quilt lapping on the hard concrete floor.

It was getting dark, and as afternoon approached, the pale rays of the sun were much dimmer.

Lu Sheng quickened his pace and hurried forward, and finally found that there were new changes, of course, he had to hurry up and take a look.

After turning around the bone-heaping hills, he quickly saw where the strange popping sound was coming from.

Directly in front of him, there was a tall mountain of bones surrounded by gray-white mist.

The surface of the mountain was full of countless giant moths lying on their stomachs, each of which was several meters long, and the longest could even reach more than ten meters in size.

They flapped their wings slowly, huddled together densely, and all stood on the mountain of bones.

From a distance, the entire Bone Mountain seemed to be completely covered with moths.

These moths exude a large amount of moth poison powder all the time, which is scattered by the wind and swept away by the gray air currents passing by from time to time.

"That's how the poison in the wind came from before daring to love?" Lu Sheng got closer, and soon discovered the cattiness of this bone mountain.

The mountain of bones beneath these moths is not a mess of ordinary bones, but a complete skeleton of a strange giant with many tails on its head.

The giant was half-kneeling on the ground, with its head bowed, with dense tentacles like octopus tentacles on the back of its neck, and gray-white membranes connecting the bones on its body.

Lu Sheng got closer, and suddenly some of the moths were alarmed, and they slowly vibrated their wings and flew up.

With this flight, Lu Sheng saw clearly that each of these moths had a large gray cocoon tied to its abdomen, and there were humans of different sizes curled up in the cocoon.

These cocoons are wrapped around the abdomen of the moth by a large number of spider-like silk threads. The people in the cocoon all looked painful and looked weird.

A large number of moths were overwhelming, almost obscuring the sky from the light, and they rushed towards Lu Sheng.

Lu Sheng grabbed a few bones on the ground on the side with his backhand, and the muscle power in his body suddenly exploded, and the bones in his hand exploded like a giant boomerang.

Puff puff!!

In the blink of an eye, a single bone pierced through three huge moths, breaking them into a mass of minced flesh.

Lu Sheng simply stomped on the ground.

Boom!!

A large number of broken bones were trampled up by the huge force, and then Lu Sheng punched him in the head, and he was hit with a bang, and the fragments suddenly exploded and splashed away.

The broken bones were like a rain of hidden weapons, densely hitting the moths in the sky, and a large piece was laid in an instant.

A large amount of gray-white slurry rained down, corroding the bones below into holes of various sizes.

Lu Sheng concocted the same method, and three times in a row, he killed and shot down a large number of moths in the sky.

He didn't dislike the air full of poisonous powder, so he jumped up directly, borrowed from the gap where there was no slurry on the ground, and soon arrived at the tall bone mountain covered with moths.

Lu Sheng stomped his foot, and the ground made a solid, thick sound.

"This mountain of bones is quite strong. ”

After a few steps up the mountain of bones, Lu Sheng soon found a metal block that clearly looked like a box.

The surface of the chest was covered in corroded rust, and a silver winged man was carved into the keyhole, which looked like a suffering sinner, and a large number of skull-carved charm chains were entwined around it.

Lu Sheng stood on the edge of the box, looking around, and the endless sea of bones around him was still desolate.

"There's been a lot to explore here in a short time.... It's a pity. "Time is running out, he has already delayed a lot of time here, and now that he can't find the divine power and has fulfilled his karma wish, it's time for him to arrange the formation to return, and it will only be a waste of time to stay here.

Reaching out and grabbing the edge of the box, Lu Sheng pulled hard.

Syllable.

The lid of the box is pulled open, revealing the contents of the box.

On a layer of black, velvety black cloth sits a delicate dark gold three-pointed fork that looks very gorgeous.

The three-pointed fork looked more like a dagger or a short thorn, the size of a palm, and the handle was inlaid with a dense mass of broken diamonds and ruby sapphires, which looked dazzling and vulgar at the same time.

The rest of the place, such as the side of the blade, is carved with a delicate vine-like pattern, which adds a lot of mystery to the whole weapon.

"There seems to be something down there. Lu Sheng picked up the three-pointed fork and sensed it, this was just a very ordinary weapon, maybe there were faint traces of special energy left, but now, the long years have made it completely lose its original power, and it has only degenerated into an extremely ordinary blade.

Lu Sheng reached out and took out the black velvet cloth from the box again, and suddenly saw a booklet hidden under the velvet cloth.

He reached for the booklet, and it was evident that it was not made of paper, but seemed to be made of some kind of animal skin.

The paper is soft and delicate, with a hint of parchment toughness.

The paper is densely packed with ghost-like text symbols, which are completely incomprehensible. Lu Sheng simply threw it into the sea pearl, kept it for the time being, and looked back and translated it slowly when he had time.

The box was empty, and he wasn't in the mood to continue wasting time here.

Immediately, he simply took out the formation materials from the sea bead and began to arrange a simple formation on the top of this bone mountain.

One by one, the black crystals continued to pierce into the ground of the bone mountain with Lu Sheng's movements, and soon formed a simple psychedelic formation.

With the cover and protection of the formation, he began to truly portray the return formation.

The returned formation was divided into many parts under the optimization of Bansai, and he only needed to depict the lines that linked these parts together.

The efficiency has been doubled.

This is also the key reason why Lusheng attaches great importance to the class competition.

After about half an hour, the formation was arranged, and Lu Sheng reached out and inserted the last black crystal into the ground, completing the last energy supply of the entire formation.

After that, he slowly breathed a sigh of relief and looked around again.

The corpses of the moths he had killed just now had been covered with a layer of gray-white silk nets, which formed a film-like thing that completely covered the corpses.

I don't know why, Lu Sheng can faintly feel that these corpses all seem to have shrunk slightly.

"It's like digesting....", he couldn't help but think of the abyss. That huge life form is also like this, quickly digesting the life that died in its own body.

"Forget it, don't worry about it for the time being. ”

Lu Sheng sat cross-legged in the middle of the formation, and he also left his back hand in Qinglutan. Even if he is not there, the subordinates who are inspired by his personality charm will spare no effort to protect Pang Yuanjun and Tang Qingqing.

What's more, he also arranged several additional dark lights, as long as there is no problem with the Qinglu Altar, it will not be inspired.

Before entering the Gray Realm, he had unexpectedly sensed that Tang Qingqing had a new pair of life breath in his stomach, and he preliminarily judged that it was very likely to be twins.
