Because Cang Nan had not entered the Immeasurable Secret Realm before, he could not provide any help to Du Yu.

At this time, Du Yu could only rely on himself.

"My sole purpose in entering the Immeasurable Secret Realm is to understand the mysteries of light and darkness. The immeasurable light, the radiance, the mystery of the light, illuminates all beings. ”

Du Yu secretly thought to himself that if he wanted to understand the mystery of light, he must know what the true essence of the mystery of light was.

The gold of the five elements represents slaughter, sharpness, and killing.

The water of the five elements, the water is soft, moisturizing all things.

The wood of the five elements, endlessly, represents the scheming of life.

The fire of the five elements, burning a qiē, an inextinguishable flame.

The land of the five elements, the virtue of carrying things, and the tolerance of one qiē.

"Master, if you want to understand the mystery of light, you must first visualize the first ray of light in the universe. The empty and infinite dark void, after the universe first opened, suddenly, a light was born, illuminating the dark world. Since then, there has been light in the world. ”

With Cang Nan's narration, in Du Yu's purple mansion, suddenly, a visualization map appeared.

Purple Mansion in the center of the eyebrows, all the light is gone.

Suddenly, the Purple Mansion in the Heart of the Eyebrows turned into an empty and lonely dark void.

The Dark Void represents eternal loneliness, the absence of hope.

Darkness means nothing, and suddenly, Du Yu felt something in his heart.

And eternal darkness represents hopelessness and despair.

Just when the soul was about to sink forever, suddenly, Cang Nan turned into a light and suddenly appeared in the purple mansion in the heart of the eyebrows.

"Hope, light represents hope!"

In the purple mansion of the eyebrows, the primordial spirit revealed gold, and the light on the merit lotus platform flickered. The golden primordial god suddenly shouted loudly.

A light represents hope, and darkness represents despair.

In the depths of despair. There will be hope.

Suddenly, Du Yu, who had come to his senses, suddenly felt that in the immeasurable secret realm, these lights had become very kind.

Du Yu seemed to turn into a ray of light and melt into the light.

"One foot of light!"

Suddenly, in the purple mansion of the eyebrows. A shone of light.

The light is one zhang thick, and one zhang of light wraps the golden primordial god thickly, and in an instant, Du Yu suddenly found that under the immeasurable light, there are many heavenly and earthly treasures.

And at this time, the center of the underworld was bloody, and Du Yu sensed that this layer of immeasurable secret realm was ten thousand zhang thick. Thousands of lights.

The immeasurable secret realm is ten thousand zhang high, and at this time, Du Yu saw that there were many figures in this sea of light.

At this time, some figures have not yet understood the mystery of light, and are still wandering on the sea of light. Some people have already understood part of the mystery and stepped into the sea of light with a part of their body.

And more figures, holding secret treasures. These secret treasures seem to have the same origin as the sea of light.

And in Du Yu's eyes, these figures have many heavy colors.

The sea tribe is blue. Demons are black, monsters are gray.

And in the Pure Land of China, all kinds of people show different colors.

"Master, you are the first to fully integrate into the sea of light. In their senses, you are nothing. Cang Nan's keen spiritual sense emanated.

Hear that. The corners of Du Yu's mouth rose slightly, but his smile was a little cold.

"In that case, wouldn't it be that in this sea of light, I am an invisible assassin. Out of sight, coming and going without a trace. ”

Du Yu turned into a part of the sea of light. This qiē is naturally all due to the scene of the first opening of the universe and the first ray of light simulated by Cang Nan in the Purple Mansion in the eyebrows.

In an instant, Du Yu turned into a sea spirit of light, and suddenly ran towards a demon.

At this time, this demon's cultivation was the peak of the Extraordinary Ninefold, and his combat power was very strong, because his whole body was filled with terrifying aura.

This earth-shattering aura means that he has gone through countless killings, and being able to survive the endless killings is absolutely extraordinary.

But unfortunately, it was Du Yu who he met. Du Yu's combat power could not be compared to that of ordinary transcendent realm geniuses.

In an instant, without using any supernatural powers, relying solely on the terrifying physical power of physical sanctification, the terrifying power of the terrifying power hit the demon's back like a mountain of seas.

In an instant, this demonic genius who had experienced a hundred battles, and his extremely powerful demonic body suddenly turned into a cloud of blood mist.

The demon was directly defeated, and an elixir that was about to be picked by him fell into Du Yu's hands.

To kill this demonic genius, he just used a knife to kill chickens.

And at this time, Du Yu completely let go of his divine thoughts.

Because Du Yu's body seemed to be turned into a part of the sea of light, Du Yu's divine thoughts covered the entire sea of light in a single thought.

"For maximum training, I still don't kill them all. Otherwise, there would be no enemies. Anyway, these Huaxia geniuses won't die, but in order not to waste time, then this so-called secret treasure can't be let go!"

Du Yu secretly thought to himself, although with Du Yu's supernatural combat power, he could completely kill all the geniuses of the three clans of the Demon Sea in this layer, but in that case, the Huaxia genius would have no opponent.

In this case, the intention to exercise is lost.

Du Yu shot one after another and captured many secret treasures, and then these secret treasures were cleverly sent by Du Yu to the side of the Huaxia genius!

With the help of these secret treasures, the Huaxia genius instantly merged into the sea of light.

After doing this qiē, Du Yu still has one last trick.

Du Yu turned into a part of the sea of light, and in an instant, the sea of light shook slightly!

Then, the genius of Huaxia was with the genius of the three clans of the Demon Sea, and he was a prison of light.

As for some evolutionaries of alien civilizations who were deeply hostile to Huaxia, they were driven by Du Yu to be with the geniuses of the Pure Land of Shenzhou!

In this case, the entire sea of light will become two huge prisons of light.

After doing this, Du Yu took one last look at this layer of the sea of light, and then turned around and headed to the next layer of the sea of light's teleportation array!

Just when the divine thoughts covered the sea of light, Du Yu discovered the teleportation array in the center of the sea of light on the first layer.

Du Yu's figure suddenly submerged into this teleportation array, and in an instant, a light rose from this teleportation array, and then Du Yu disappeared on the first floor!

At this time, Du Yu had already guessed.

The Immeasurable Secret Realm must be divided into many layers, the first layer of the Sea of Light, the highest cultivation is no more than the Transcendent Ninefold, and none of them have entered the Holy Realm.

Through the guò teleportation array, he came to the next layer, that is, the second layer of the sea of light, under Du Yu's divine thought, in this layer of the sea of light, all of them were first-order powerhouses!

It's just that at this moment, Cang Nan suddenly reminded: "Master, when I was on the first layer, my spiritual sense detected that half of the geniuses in the first layer of the sea of light were black, and the other half were red. At that time, I guessed that the chance of survival in this layer of light was 50%. In other words, in the end, the Infinite Secret Realm will be closed, and half of the geniuses of the first layer will die!"

"At first, I thought this speculation was an illusion, but now, in this layer, all genius cultivation is a first order, and among the five geniuses, only two geniuses can leave alive. In that case, the survival rate is 40 percent. ”

Hearing Cang Nan's words, Du Yu immediately said: "If this is the case, then the survival rate of the next layer is thirty percent!" (To be continued......
