Crystal skeleton.
After Lu Sheng learned about this strange thing from his father Pang Yuanjun, he immediately made all preparations for going to the Gray Realm.
If it is said that at the beginning, he had a certain exploration mentality that he could go or not, then after learning about the crystal skeleton, his interest in the gray world became much greater. In addition, the gray world actually has a time flow difference, which made him have slight doubts about whether the gray world belongs to this world.
In his many experiences of coming to other worlds, only in different time and space in different worlds can this kind of abnormal flow of time occur.
Time and space, in the normal universe, often go hand in hand. Changes in space also cause distortions in time.
After more than three days of preparations, in order to prevent the closure of the gray world, Lu Sheng followed the relic cave recorded by the half-demon organization, went deep into it, and went to the gray world for the second time.
call! !
The second time he jumped down from the cave exit, Lu Sheng looked far away in mid-air.
Before entering the pool, there is a large expanse of plains around, and these plains do not seem to belong to this world, but more like a transitional environment.
If he didn't have enough time, he would like to explore the surrounding world where this plain is located.
Boom! !
His body fell into the bone-chilling water, and Lu Sheng released a scorching hot breath all over his body. This is the terrifying heat that his extremely powerful heart naturally radiated with the beating of his heart after he was promoted to Emperor Wu.
The current him, if he doesn't deliberately restrain himself, is basically a fierce monster exuding huge energy and blood heat.
This is the supreme state of the Martial Emperor in this world.
Not only can he exude this terrifying aura, but he can also freely manipulate the stream of hot air escaping from his pores.
Lu Sheng quickly swam back into the underwater honeycomb channel amidst the rumbling bubbles.
Going all the way along the channel, after swimming for a few minutes, he suddenly accelerated upwards.
Soon, with the sound of splashing water, he jumped up from the pool, stepped lightly on the water surface for a few steps, and landed on the edge of the pool to stand still.
"It's still the same." Lu Sheng looked around, but found nothing, except bones.
Biting cold wind poured in continuously from the surroundings, and there was no breath of the living in the wind.
Lu Sheng's body was hot, and a large amount of white water vapor quickly evaporated from his clothes.
After drying his clothes, he didn't rush in the previous direction, but followed another direction, running with all his strength at will.
The heavy footsteps of bang bang bang continuously smashed terrifying deep pits with exaggerated diameters on the ground.
Lu Sheng was wearing the wide hard cloak specially prepared this time. After jumping up, he grabbed the edge of the cloak, and he could fly forward a certain distance quickly like a glider.
This is the simple equipment made by Lu Sheng recalling the principle of the earth glider.
Saved him a lot of energy.
After sprinting at full speed for hundreds of kilometers, the sea of bones, which had been monotonous, finally had a new change.
Large swaths of gray whirlwind, do not know when to start filling the surrounding sky.
As soon as Lu Sheng entered this whirlwind, he immediately felt a subtle poisonous powder mixed in it that would cause hallucinations and stupor.
"Poisonous wind?" He couldn't help speeding up, and it took more than half an hour to pass through this gray air current.
After another hour of tedious rushing, Lu Sheng planned to set up the magic circle and return to the Heavenly Demon Realm as he planned to see nothing more valuable.
Staying here is definitely a waste of time.
puff!
Suddenly, there was a faint popping sound from the large pile of bones in the distance. This sound sounded like a thick quilt slapping on the hard concrete floor.
It was getting late at this time, and as the afternoon approached, the pale sun's light also dimmed a lot.
Lu Sheng quickened his pace and hurried forward, and finally found a new change, so of course he had to hurry up and take a look.
After turning around a hill of bone piles, he quickly saw clearly where the weird popping sound came from.
Right in front of him, there is a tall bone mountain surrounded by gray-white mist.
On the surface of the mountain, there are countless giant moths lying on their stomachs. Each of these moths is several meters long, and the longest one can even reach a size of more than ten meters.
They flapped their wings slowly, crowded together densely, and all stood on the bone mountain.
From a distance, the entire Bone Mountain seems to be completely covered by moths.
These moths emit a large amount of moth poison powder all the time. The poison powder drifts with the wind and is swept away by the passing gray air current from time to time.
"Is this how the poison in the wind before Ganqing came from?" Lu Sheng moved closer, and quickly discovered the trickiness of the bone mountain.
The bone mountain below these moths is not a mess of ordinary bones, but a complete, weird giant skeleton with many tails on its head.
The giant half-kneeled on the ground, with its head bowed. There were dense tentacles like octopus tentacles on the back of its neck, and gray-white membranes connected the bones on its body.
Lu Sheng got closer, and suddenly some moths were startled, and they slowly flapped their wings and flew up.
It was only after this flight that Lu Sheng saw clearly that each of these moths had a large gray cocoon tied to their abdomen, and humans of different sizes were curled up in the cocoon.
These cocoons are wrapped and attached to the moth's abdomen by a large number of spider silk-like threads. The people in the cocoon all looked pained and strange.
A large number of moths covered the sky, almost covering the sky with light, and rushed towards Lu Sheng.
Lu Sheng grabbed a few bones on the ground with his backhand, and his muscles burst out suddenly. The bones in his hand shot out like a giant boomerang.
Puff puff! !
A bone pierced through three huge moths in a blink of an eye, smashing them into a ball of minced meat.
Lu Sheng stomped hard on the ground.
Boom! !
A large number of bone fragments were stepped into the air by a huge force, and then Lu Sheng punched them in the head, hitting them with a bang, and the fragments exploded and scattered.
The broken bones were like a rain of hidden weapons, hitting the moths in the sky densely, and felling a large piece in an instant.
A large amount of gray-white slurry rained down, corroding the bones below into pits of various sizes.
Lu Sheng followed the same pattern and killed all the moths in the sky three times in a row.
He didn't dislike the air full of poisonous powder, so he jumped up in one step, borrowing strength from the gap where there was no slurry on the ground, and soon reached the tall bone mountain covered with moths.
Lu Sheng stomped his feet, and the ground made a solid and thick sound.
"This bone mountain is quite strong."
Walking up the bone mountain for a few steps, soon at the top, Lu Sheng found a metal block that looked like a box.
The surface of the box is full of corroded rust, and a silver winged figure is carved at the keyhole, which looks like a suffering sinner, with a large number of pendant chains engraved with skulls wrapped around its body.
Lu Sheng stood beside the box, looking around, the surrounding area was still desolate and endless sea of bones.
"I can't finish exploring here in a short time... It's a pity." Time is running out, and he has already spent a lot of time here. It's time to arrange the return array, and staying here will only be a waste of time.
Reaching out to grab the edge of the box, Lu Sheng pulled it hard.
Bang.
The lid of the box was pulled back, revealing the contents.
On a layer of black velvet-like black cloth, there is a delicate dark gold three-pronged fork that looks very gorgeous.
The three-pronged fork looked more like a dagger or a short thorn, only the size of a palm, and the handle was inlaid with a large number of diamonds and red 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 delicate vine-like patterns, adding a lot of mystery to the whole weapon.
"There seems to be something down there." Lu Sheng picked up the three-pronged fork and sensed it. This is just a very ordinary weapon. Maybe there were faint traces of special energy left, but now, the long years have made it completely It lost its original power, and only degenerated into an extremely ordinary weapon.
Lu Sheng reached out and took out the black velvet cloth from the box, and suddenly saw a booklet hidden under the velvet cloth.
He reached out to pick up the booklet, and it was obvious that the booklet was not made of paper, it seemed to be made of some kind of animal skin.
The paper is soft and delicate, with a slight hint of the toughness of leather paper.
The paper is densely packed with ghostly symbols, which are completely incomprehensible. Lu Sheng simply threw it into the Fuhai Pearl, and kept it temporarily, and then slowly translated it when he had time.
The box was empty, and he was in no mood to continue wasting time here.
Immediately, he simply took out the formation materials from the sea-covering pearl, and began to arrange a simple formation on the top of the bone mountain.
The black crystals pierced into the ground of Bone Mountain continuously following Lu Sheng's movements, and soon formed a simple psychedelic formation.
With the cover and protection of the formation, he began to truly describe the return formation.
Under the optimization of Ban Sai, the returned array was divided into many parts, and he only needed to describe the lines linking the combinations of these parts.
Compared with before, the efficiency has more than doubled.
This is also the key reason why Lu Sheng attaches great importance to Ban Sai.
About half an hour later, the array arrangement was completed. Lu Sheng reached out and inserted the last black crystal into the ground, completing the last energy supply for the entire array.
After that, he slowly breathed a sigh of relief, and checked the next four weeks again.
The corpses of the moths he killed just now were covered with a layer of off-white silk screen at some point, and these screens formed a film-like thing that completely covered the corpse.
For some reason, Lu Sheng could faintly feel that all these corpses seemed to have shrunk slightly.
"It's like digesting..." He couldn't help thinking of the abyss. The huge living body is also like this, quickly digesting the life that died in its body.
"Forget it, don't care about it for now."
Lu Sheng sat cross-legged in the middle of the formation, and he also left behind in the Qinglu altar. Even if he is not there, the subordinates who are inspired by his personality will spare no effort to protect Pang Yuanjun and Tang Qingqing.
What's more, he also arranged several additional secrets, as long as there is no problem in the Qinglu altar, there will be no enlightenment.
Before entering the gray world, he had already unexpectedly sensed that Tang Qingqing had a new pair of life breath in his stomach. According to his preliminary judgment, it was very likely that they were twins.
