The movements of the two mysterious people in black robes were the same, one stretched out his left hand, and the other stretched out his right hand, and the middle of the two hands emitted violent fluctuations of demonic energy.

The demonic qi rose into the air, and several big black characters appeared in the air on top of the two black vortices - the Xuanmen of Life and Death!

Just when Wang Yuan was surprised, a divine sense sounded in his mind.

"Fellow Daoist, you must be able to break through the previous formation, your cultivation has reached the realm of the Great Perfection of the Void Netherworld. An old voice rang out, a little muffled.

Wang Yuan didn't dare to move, but he was surprised in his heart, "Could this voice be the master of the Cave Mansion? That Void Netherworld Demon Dao Master? And why does he say that my cultivation is the Void Netherworld?"

The old voice continued, "I don't know if future generations will remember the name of my Red Blood Demon Lord. ”

In Wang Yuan's memory, he knew the level in the demon world, and he was a master at the level of the demon lord, but the demon lord he was talking about was not the demon lord of the demon realm, but a title.

"Before building this cave, I met a person!" said in an old voice, "He doesn't belong to the mortal realm, but from the other five realms!"

"The people of the other Five Realms want to enter the mortal realm, except for the special passage, only the arrogant strength can break through the barrier between the two realms, but the passage is in the hands of the super forces of the Five Realms, this person is not like a person in those forces, so his strength can be seen!"

"At that time, I was a cultivator of the Great Perfection of the Void Netherworld, and the title of the Red Blood Demon Lord was also what outsiders called me, when I met this mysterious person, I saw that he was extraordinary, and I wanted to follow him, but I didn't succeed!"

Wang Yuan stood there, listening carefully to what the Red Blood Demon Lord said, this was a secret, and Wang Yuan also wanted to know what was going on.

"It wasn't that the man didn't agree to my request, but he gave me a chance, he asked me to answer a question in one breath, but I didn't think of a way until three breaths!"

Wang Yuan was stunned for a moment, and thought: "The Red Blood Demon Lord is a Void Immortal Great Perfection cultivator, and the calculation is already very terrifying, but that question made the Red Blood Demon Lord two breaths late to answer, what kind of question is that?"

Let Wang Yuan be in reverie, but the Red Blood Demon Lord is still talking to this "Taoist friend".

"By the time I answered after three breaths, the mysterious man had already left, and I missed the opportunity!" sighed the Red Blood Demon Lord, one can imagine how frustrated he was at the time, the opportunity to follow a super strong man is not available to everyone.

"I lamented that opportunity, but that problem was reserved for me, and I built this cave for that problem. The Red Blood Demon Lord continued, "From the Demon Infant Stage, if you want to break through, you need to comprehend the Demon Source, this is just a wisp of my divine sense, I don't know what the Demon Source of your comprehension is. ”

"Demon source, isn't that the source of immortals for cultivating immortals, the demon infant stage is also the Yuan infant stage, it turns out that what is needed to break through after the Yuan Infant stage is comprehension!" Wang Yuan learned that only those who belonged to the Yuan Infant Stage masters and above could know the secrets.

It's just that this secret is not a big shocking secret, and it is called a secret to this news with the status of the Linyuan faction.

"After the construction of this cave mansion, because of that strong man's test of me, it resonated with my demon source, and I broke through to become a Dacheng stage realm!"

Wang Yuan was also stunned, it was rumored outside that the land of the Demon Pool was an abandoned cave mansion of a master of the Demon Dao of the Void Underworld Period, but he didn't expect the Red Blood Demon Lord to break through and become a Dacheng Stage, so it means that this Cave Mansion has also become a Dacheng Stage Master's Cave Mansion!

This series made Wang Yuan suddenly enlightened.

"The Donghua faction is a second-class sect, I now understand why the land of the demon pool has not been destroyed, this is already a cave of masters of the Dacheng period, presumably with the heritage of the Donghua faction, it is impossible to send a few masters of the Mahayana period for an abandoned cave, in case of a loss of a few, then the status of the Donghua faction will be shaken!"

The Red Blood Demon Lord said again: "I have set up a formation here, and only those who have cultivated to reach the Great Perfection of the Void Netherworld Period can pass through this hall, and there have been people who have come here before, but they died because I didn't answer the questions I asked. ”

Wang Yuan's mind was like being struck by a thunderbolt, and he roared, exclaiming: "Question, is it dead? Could it be that this Red Blood Demon Lord is here to ask the mysterious man's question, and if he can't answer it, he will die here!!"

First of all, according to what the Red Blood Demon Lord said, Wang Yuan was seventy percent sure that the problem of the Red Blood Demon Lord was related to the Demon Source, that is, the Immortal Source, but Wang Yuan was only in the Qi cultivation period, how could he answer the question of that realm!!

"Could it be that Wang is going to die here again!" Wang Yuan's heart plummeted, "Alas, the Demon Dao master Red Blood Demon Lord must be a murderous person, I didn't expect to build a cave mansion just to ask people questions, and if I couldn't answer it, I was blown into slag by this master of the Dacheng stage!"

"Hehe, whether Daoyou has many questions, but with Daoyou's strength, there is still a chance, it depends on Daoyou's understanding of the Demon Source. The Red Blood Demon Lord's voice disappeared here.

The two black vortices in front of Wang Yuan suddenly turned, and they were made of demonic energy.

Under the rotation, both vortices began to change, from the original black to black and white, half black, half white, and the same is true for both vortices.

Wang Yuan looked at the big words "Life and Death Xuanmen" on the vortex, and thought in his heart what the problem of the Red Blood Demon Lord was!

The disappearing voice sounded again, "After the mysterious man asked this question, I thought carefully in this cave, this person's comprehension of the 'source' is very powerful, even if it is caused by the question, it can make people confused, and those who do not have concentration will lose the demon heart (Dao heart). ”

"Don't talk nonsense, hurry up and ask!" Wang Yuan thought that he was dead, so it was better to see what the "source" was.

Perhaps after hearing what Wang Yuan said, the Red Blood Demon Lord explained: "When Daoyou entered the cave, did you go through the teleportation array of three whirlpools, hehe, that is my understanding of the mysterious person's 'source', but the previous efforts were wasted, and I almost lost my 'demon source', and those three whirlpools were also placed there uselessly, and staying there was just to scare some juniors who were not cultivated enough, haha!"

If the ghost invisible, Yan Zhen, and the beautiful young woman of the demon clan knew that the three whirlpools of "life and death", "life and death", and "death and death" were used to scare people, then they would definitely scold this red-blooded demon lord.

"The formation after the whirlpool is the most important, and only when the cultivation reaches the level of cultivation like Daoyou can it be passed. "How could the Red Blood Demon Lord have thought that Wang Yuan was only a solid stage demon cultivator.

Wang Yuan also smiled bitterly, although he came here after real life and death, he took advantage of the loopholes, and he was not a real master of the Great Perfection of the Void and Netherworld Period.

"Daoist friends should adjust their mentality and protect the demon source they have comprehended, and we can't shake the 'source' that the mysterious person led out in the form of a question!

"I'm going to start asking questions. The Red Blood Lord finally reminded.

Wang Yuan also began to concentrate, he didn't comprehend any "demon source", and he didn't need to protect it, staring at the two black and white whirlpools in front of him with wide eyes, with Wang Yuan's keen insight, the problem of the Red Blood Demon Lord might be related to it.

"What you see in front of you are two doors!"

"One is the door of life, the other is the door of death!"

"There is one person standing in front of the door, one who tells the truth, and the other who tells lies!"

"Now you can only ask one of them one question, how can you enter the door of life smoothly! This is the question, the mysterious powerhouse gave me a breath of time, I used three breaths to answer, not the old man is conceited, there are not many people in the mortal world who answer this question within three breaths, now the Taoist friends have five breaths of time, answer this question that is drawn out by the 'source of life and death' in the form of a question, and test your understanding of the 'source', start now!"

As the sound faded away, the place became silent in the here and now, except for two whirlpools divided into black and white, and two people standing there silently.

Quiet!

It's so quiet!

Wang Yuan used the cultivation of the Qi cultivation period to answer the question that even the masters of the Void Underworld Period needed three breaths of time to answer, how could he possibly answer it!?

In fact, after the Red Blood Demon Lord finished saying this question, Wang Yuan had already begun to think about it, and the time of five breaths was turned into six breaths by him!

How short is the time of six breaths? One breath and one breath are one breath, which means that after Wang Yuan can't answer this question, he will have six breaths of time left!

Urgent!

Time is in a hurry!

Not only are the demon clones thinking hard, but the deities and clones of the Linyuan Sect who are far away have already sat down cross-legged and frowning and thinking!

Time passed quietly, and there was no clue about this breath!

"The source of life and death, the door of life and death, two people, one true and one false!" these words flashed through Wang Yuan's mind, these were all the key words in the question of the Red Blood Demon Lord.

If a master of the Yuan Infant Stage comes here, then when he sees this door of life and death, and thinks about this "source of life and death", he will spurt blood more than once, and it is all painstaking work, if he is unlucky, Yuan Ying will return to Jindan, and the realm will fall.

If a master of the Cave Void Period comes here, then the pain he suffers is even stronger than that of a person in the Yuan Infant Period, this is a test of the "source" of comprehension, the higher the realm, the more difficult it is to understand this "source of life and death", and his "source" will be lowered by one level and return to the Yuan Infant Period.

However, if you answer this question, it is to complete a tempering of the "source" of your own comprehension, not only will the "source" be greatly improved, such as the Red Blood Demon Lord will soon break through to the Dacheng stage, this is not a great opportunity!

After a while, after three breaths, Wang Yuan closed his eyes and sat cross-legged, not looking at the whirlpool in front of him.

His strength is low, and he has not comprehended the source of the demon, so he will not suffer any impact, but his face is getting paler.

The brain is clear, only two big words in the mind, one side is the new word, the other side is the dead word, and black and white do not violate each other.

"What is life, what is death?" this question surrounded Wang Yuan's mind, and even he had forgotten the question of the Red Blood Demon Lord.
