There is actually a reason why luminous sand is so rare, in all bats and their secretions, there is luminite sand.

However, there are very few that can really be used as luminite sand, because only monks above the Golden Immortal Realm can use its secretions as luminite sand.

If the bats reach the Golden Immortal or above, they almost do not need to excrete, and even if they do, they need to wait for 10,000 or even 100,000 years to excrete once, and this time there are very few luminous sands that can be born, at most only a few dozen grains, it is conceivable that it is not enough to even give it to one person.

The reason why luminous sand is so precious is not only because it belongs to the innate spiritual objects of the world, but also has another wonderful use, it can open up the life of the double pupils and derive the mysterious pupil technique.

From ancient times to the present, the birth of any pupil technique is nothing more than a few conditions.

The first day is born sacred, and when he is born, he carries pupil techniques, such as innate yin and yang eyes, ancient double pupils, golden eyes, etc., and some pairless eyes.

The second is to cultivate oneself and create a pupil technique, which is the most energy-consuming and time-consuming, because creating a pupil technique is no less than creating two or three divine channel techniques of the same level.

It's not that the pupil technique is difficult to create, but the eyes are the most difficult part of the human body, and if you are a little careless, you can only change a pair of pupils, so there are few people who create the pupil technique, after all, the gains outweigh the losses.

The third is Luminous Sand and a small number of spiritual objects that have the ability to open up the life of the pupil technique, they can give you some kind of pupil art!

And the luminous sand is one of the best, the pupil techniques opened up by the luminous sand are all different, they are based on the laws of the Great Dao that they have cultivated, and the Heavenly Dao is naturally opened up, and they are closely related to themselves, so they are so precious.

However, one eye needs at least thirty grains to open up the pupil technique, and if you want to open up the most suitable one, you need one hundred grains for each of the two pupils to perfectly open up a natal technique!

If it is a chance encounter, it is rumored that you can have two different pupil techniques, such as the space-time divine pupil, the innate yin and yang eye, the causal extinction divine pupil, etc., some specific pupil techniques.

And looking at this yellow treasure chest, there are at least three or four hundred grains of luminous sand, which is enough for Tang Long to open up a complete pupil technique by himself!

"Start with a drop in each of the two pupils!"

Tang Long didn't hesitate, he directly picked up the luminous sand and dripped it into his pupils, and in an instant, the luminous sand naturally turned into a small drop of water, dripping into his eyes.

In the depths of the pupils, there was a portal that seemed to be slowly opening, and a thread, a wisp of origin blood gradually flowed into it, and then I felt it at all.

"It's no wonder that luminous sand takes a long time, dripping in every day, and this is the key. Tang Long sighed slightly.

I feel quite clearly that in my eyes, the wonderful runes and dense runes are changing, ever-changing, and at the same time, a drop of origin blood, like nourishment, is constantly nourishing these runes and runes, so that they can evolve faster and evolve into mysteries.

It is as if there is a space in the eyes that is slowly opening up to people, opening bit by bit, not in a hurry, not in a hurry, as if to take it slowly, bit by bit to stabilize the space, nourish the space.

Therefore, the first to give the space a cleaning and paving, this process is slowly moving forward, is a huge project.

"Whoa......

With a wave of his hand, Tang Long sent the luminous sand into his own cave world, because the cave world was the safest, and no one could open the cave world without his permission.

Dare to forcibly break open the Cave Heaven World, the Cave Heaven World will destroy itself at the moment it is broken, and no means are required, so the protection is quite in place, and it also reassures Tang Long that he is not afraid of any thieves, and he can put all the innate spiritual objects and rare treasures into it with peace of mind.

"This dream is about to collapse, why don't you fulfill my Cave Heaven World, and let the Pangu World go further on the road of the Cave Heaven World. Tang Long thought to himself.

After the death of the true master of the dream world, the dream will face the danger of collapse, this collapse refers to all the power of the dream, in addition to the dream power contained in the dream master himself, there is also the vast majority of the dream power in the dream, otherwise it is difficult to form a completed dream.

In the dream realm, the master of the dream realm is equivalent to a key, or the needle of the sea god, as long as there is the master of the dream realm, survive, the probability of the dream collapsing is quite small, of course, there are, such as destroying the cornerstone, the great supernatural person will take action.

In addition, there is also the power of the dream that is absorbed by the dream world, and the continuous extraction of the power of the dream will also collapse.

And these dreams after the collapse will fall down, evolve some strange objects or creatures, and even reflect reality.

But in a quarter of an hour when the dream realm collapsed, a massive amount of dream power burst out, which can be said to give Tang Long a great opportunity.

His Pangu world and Hongmeng Heavenly Emperor diagram can both absorb all things as nourishment, whether it is the power of dreams or others, they can be turned into nourishment and nourish their own bodies, which is a rare treasure.

This is also one of the reasons why many monks on the Flood Desolate Continent who possess the Cave Heaven Treasure are willing to enter the Void Battlefield.

Because, the cave world can turn the corpses of the exotic demons it kills into nourishment, and constantly nourish its own cave world.

This is also the reason why on the Flood Desolate Continent, some Heavenly Masters accumulate so fast, they can directly plunder the exotic demons, so it is almost rare to see the corpse of the Eternal Night Hengsha on the Void Battlefield, because within the first time, it has been incorporated into its own Cave World for decomposition.

"Boom ......"

With a loud bang, the entire dream space seemed to be caught in a storm, the world was turned upside down, the universe was reversed, the mountains were everywhere, the rivers were collapsing, the space collapsed, and pieces fell downward.

At this moment, a vast and boundless colorful brilliance burst out, like rain, spreading out to all directions, like a sea king who was surging endlessly and setting off stormy waves, and fluttered the whole world one after another.

"Whoa......

Seeing this scene, Tang Long was not pretentious, nor polite, with a wave of his hand, the Natal Treasure Hongmeng Heavenly Emperor Diagram immediately shrouded out, turning into a Origin Black Hole, continuously absorbing the power of dreams, and finally being decomposed by the chaotic qi.

Like a tsunami in the Hongmeng Heavenly Emperor diagram, a steady stream of majestic aura of creation poured out, opening up the array space and linking them together.

In addition, Tang Long's Pangu world opened, and a huge attraction was instantly drawn, directly pulling the power of the dream realm within a radius of dozens of miles, turning into a huge vortex.
