I have indeed heard of this incense valley before, at that time, their incense was at its peak, and it could be said that it was the first alchemy cave heaven in the fairy realm. Their valley master burned the sin, and his alchemy was unparalleled. There are even rumors that this person is able to refine the Heavenly Rank Spirit Pill, and the reason why the Burning Incense Valley has changed is most likely related to his alchemy. Legend has it that a mysterious person found Burning Sin and wanted him to refine a mysterious elixir for him. The mysterious man said that he would provide all the medicinal materials needed for refining the medicine, and that he only needed to use the hands of the burning sin and the furnace. Moreover, the mysterious man also told the burning sin that his refining of medicine must be kept secret from everyone, otherwise, the entire incense burning valley would be buried for the burning sin. The world seemed to have heard of the Incense Valley, and when he saw Ling Yu's shocked face, he recalled for a moment, and finally remembered the matter of the Incense Valley, so he said to Ling Yu.

"Then, what about later? Who was the person who found the Burning Sin Refining Medicine in the first place? He actually dared to order the Burning Sin in such a threatening tone, and as the helmsman of the First Refining Medicine Cave Heaven in the Immortal Domain, he shouldn't be afraid of the mysterious person, right?" Ling Yu had never heard what the Realm said, so Ling Yu asked the Realm.

"You're wrong, Burning not only promised the mysterious man, but also cut out his own tongue in front of him! According to my guess, the mysterious man was too powerful to refuse him. But no one knows who the mysterious man is. Kai shook his head and sighed.

Hearing Jie's words, Ling Yu swallowed fiercely. He didn't expect that the Burning Sin would actually yield to the mysterious person, it stands to reason that the Burning Incense Valley, as the No. 1 Refining Medicine Cave Heaven in the Immortal Domain, should be an existence that all the forces in the Immortal Domain want to win over. As long as the burning sin raises its arms, it will echo in all directions. But he didn't, he chose to give in, and even cut off his tongue in front of the mysterious man to show that he would keep his mouth shut. In this way, I am afraid that there is only one result, and that is that the mysterious man is too powerful. It is so strong that it is not afraid of the heritage of the Incense Valley, and even, it is not afraid of any force in the Immortal Domain. So, who is he? He has such strength. Moreover, through this incident, Ling Yu felt that the mysterious man was by no means a good person. Obviously, he had a request for others, but he forced the other party to cut out his tongue to show his loyalty, and it was impossible for the cultivation of a mysterious person to have no time to stop the burning of the crime, but he didn't do it, it was really vicious.

Thinking of this, Ling Yu suddenly remembered another thing, since the mysterious man had a cultivation against the sky, and he couldn't refine the kind of pill he needed, it also meant that the pill he wanted to refine for him was definitely not an ordinary pill, and it might even be contaminated with some cause and effect.

Ling Yu frowned slightly, and asked softly, "So, what kind of elixir did the mysterious person let Burning Sin refine for him? Using this kind of almost persecutive way to make Burning Sin refine his medicine, I'm afraid that kind of elixir is not an ordinary elixir, right?" Or, that kind of elixir is beyond the scope of normal elixir?"

Hearing Ling Yu's inquiry, a hint of approval appeared in the eyes of the world, he nodded lightly, and said with a solemn face: "Yes, although no one in the world knows what kind of elixir the mysterious person wants to refine for him, but several of the medicinal materials in that medicine list have flowed out. One of the most frightening things is the three flavor medicines, which are called Heavenly Tears, Earth Marrow, and the Ninth Evil Heart! I have not heard of Heavenly Tears and Earth Essence, nor do I know about them, but I know the Nine Evil Hearts. Because to be precise, it is not a medicinal herb, but a real flesh and blood heart. The heart of the nine evildoers can only be obtained from the human body, the medicine is as its name suggests, the heart of the nine evildoers is the reincarnation of the ninth life, each life is the heart of the heinous wicked, in the ninth life, he has committed all the sins in the world. Only this kind of human heart can be called the heart of the Nine Worlds of Evil, and the way of obtaining this kind of Nine Worlds of Evil hearts is also extremely cruel. ”

"Whoever wants to gain the heart of the wicked of the ninth world must be imprisoned, and the first nine days he must be fed the blood of a boy who is nine months old, the second nine days he must be fed the blood of a girl who is nine months old, and finally he must be starved for nine days, thirsty for him for nine days, and trapped for nine days. Forty-five days later, the blood of the boy and girl in the body of the Ninth Wicked had also been incorporated into his blood. At this time, cut off his hands and feet again, and let his blood drip out. He was also very particular about cutting off his hands and feet, to ensure that he would not die within nine days, and if he died in the last nine days, everything he had done before would be in vain. It took fifty-five days for the sword-wielder to be able to take out the heart of the wicked of the ninth generation. This kind of practice can no longer be called simple cruelty, it is simply cruel and unreasonable, and it has lost all conscience!" When the world talked about the hearts of the nine evildoers, his eyes were filled with complexity.

Hearing the explanation, Ling Yu swallowed his saliva fiercely, and cold sweat seemed to rise from his spine and rushed straight to the heavenly spirit. This practice of winning the hearts of the Ninth Evil Soul made Ling Yu feel cold all over his body, he thought that killing people was not too much, but he never thought that there would be such a vicious method in the world to obtain the heart refining medicine.

"Actually, it is not for nothing that the mysterious man found the burning sin, the people in the entire sea of stars know that there is an incense valley in the fairy realm, and they also know that the burning sin is the valley master of the incense valley, and the alchemy attainment is unmatched. So, sometimes, it's not always a good thing to be in the limelight for a while!" Jie sighed lightly.

"Burning sin is not a fool, he shouldn't do this kind of thing that goes against the way of heaven! Because when he cultivates the elixir that the mysterious man needs, even if the mysterious man doesn't kill people and kill his mouth, the cause and effect contaminated by this furnace of elixir may not be something that Burning Incense Valley and Burning Sin can bear, right?" Ling Yu asked tentatively.

"In that case, a lot of things were no longer justified by burning. As far as I can guess, the mysterious man is so powerful that he can wipe out the entire Incense Valley with a single force, and he has no choice but to put the lives of his clan and disciples on the line. The Burning Incense Valley is the number one alchemy cave heaven in the immortal realm, and no one can practice that mysterious elixir except for burning sins. Everyone knows that there are three major backgrounds in the Incense Valley, "Incense Burning", "Forgetting the Furnace and Burning Sin". And these three major backgrounds are also the biggest guarantee for the success of this furnace pill. "Incense Burning" is the most holy book of the Incense Valley, recording all the alchemy secrets in the world, and the Forgetful Furnace is also known as the first furnace in the fairy realm. Someone once asserted that the alchemy of burning sin was the best in the world before and after, and his alchemy was incomparably profound, and his skills were close to the Tao. Whether it is the control of the heat, the grasp of the medicinal effect, or the degree of refining of the herbs, they have all reached an unattainable realm. Even if future generations can give birth to a Dan Dao genius, they will not be able to compare with Burning Sin, let alone surpass him. Jie recalled the burning sin in the Immortal Realm and explained.

"What about later? Is the furnace elixir refined?" Compared to the past of the Incense Valley, Ling Yu wanted to know the final result of the turmoil. Since Sin Burning is not qualified to refuse the mysterious man, then he will definitely go all out to refine the elixir. In his heart, the clansmen of Incense Valley and his disciples were extremely important, and he couldn't choose who to be, otherwise he wouldn't have chosen to succumb to the mysterious man. However, Ling Yu also knew that the furnace pill was by no means an ordinary holy medicine, and it was not even an elixir to heal cultivators. Not to mention the miraculous materials such as the Heavenly Tears and the Earth Marrow, the Ninth Evil Heart alone is not something that normal people can take.

Later, Burning Sin promised the mysterious man and decided to help him refine the medicine. However, since he started the furnace, strange things have happened one after another. As I told you just now, the Incense Valley has three major heritages, "Incense Burning", "Forgetting the Furnace" and "Burning Sin". However, when Sin Burner placed the first herb given to him by the mysterious man in the Furnace of Forgetfulness, the flame in the furnace was extinguished. No matter how much the burning sin poured the grease of the beast, and no matter what kind of flame he used, the fire could not be lit. In desperation, he had no choice but to invite the Forgotten Life Furnace to a magma and bake the walls of the furnace with the magma fire, hoping to refine the herbs. I thought that if the problem of the furnace fire was solved, he would be able to refine the medicine smoothly, but unexpectedly, on the second day of the furnace, another accident occurred. The alchemy method in "Incense Burning" is actually ineffective against the herbs in the furnace, and the flames cannot melt the herbs. The burning sin went through the entire "Incense Burning Record", but in the end it was to no avail. ”

In fact, at that time, Burning Sin had already realized the danger, but his people were in the hands of the mysterious man, and he had no way out. After meditating in the secret room for seven days, he finally thought of a way to refine herbs, and while adding that method to the "Incense Burning Record", he used a new method to refine the elixir. But he didn't know that his nightmare had just begun. Since the fire began to burn and the herbs began to melt, he was awakened by nightmares every day, in which he saw the mountains of corpses and the sea of blood, saw the immortal realm about to fall, and even saw himself and his people turn into powerful ghosts, wandering in the darkness all day long, and could not be reborn. When he refined the elixir to the ninth day, the first deceased appeared in the clan. The dead cultivator was the distant uncle of the Burning Sin, and when the cultivator of the Burning Incense Valley found his uncle, his uncle's eyes bulged out and his pupils dilated, as if he had seen something extremely terrifying. His heart had shattered, but no scars had been found on his body. On the tenth day, another cultivator died, and that cultivator was the distant brother of Burning Sin, and he died in the same way as Burning Sin's uncle, with protruding pupils, bleeding from his seven orifices, and a terrifying death. ”

"And from that day on, every day there will be relatives who have been burned to die inexplicably, and they will die exactly the same. The burning sin thought of giving up, but the mysterious man said that it would take eighty-one days to refine this furnace of elixir, and if the burning sin was refined into an elixir, it would only kill more than seventy people. But if the sin is abandoned halfway, then everyone in the Incense Valley will die. This includes, but is not limited to, his relatives, but also his disciples, and even other sects that are friendly with him. Burning Sin knew that he had been driven to a dead end. He couldn't resist the obscenity of the mysterious man, so he could only swallow his anger, hoping to refine the elixir as soon as possible. ”

However, on the night of the eightieth day, something unexpected happened. That night, the burning sin vanished, along with the mysterious man. In the early morning of the next day, the cultivators of the Incense Valley did not know what had happened or what they knew, and before noon, the Incense Valley was completely reduced to a borderless land. disappeared along with the Burning Sin, the Mysterious Man, and the cultivators of the Burning Incense Valley, as well as the other two major opportunities of the Burning Incense Valley, the "Burning Incense Record" and the Forgotten Life Furnace. As for the various precious herbs in the Incense Valley, they were not taken away. After learning of this, almost all the immortal realm forces flocked to snatch the elixir in the Incense Valley. Since then, the Incense Valley has gradually faded out of the field of vision of the Huaxia cultivators, no one knows where they went, and what happened that night has become a mystery. The Realm Chief sighed and said.

"Such a sect that is revered as the No. 1 Alchemy Cave Heaven in the Immortal Realm suddenly disappeared, can't the descendants really not find any clues?" Hearing the past of the Incense Valley mentioned by the realm, Ling Yu sighed for a while. Unexpectedly, a cave blessed land that was enough to shock the nine heavens disappeared inexplicably, which is indeed emotional.

"No, the whole Van Heong Valley seems to have disappeared into thin air, leaving no clues. Of course, there are also a lot of speculations among the many forces in the Immortal Realm. Some people say that on that night, in fact, the elixir had been refined, and it was the opportunity of burning sin and greed that was enough to change his life, so he fled with the furnace of forgetting life. And after he left, the cultivators of the Incense Valley also migrated and hid into the barren mountains in order to escape the pursuit of the mysterious people. It is also said that when the pill was refined a day earlier, it was a mysterious person who killed people and killed people, so after killing the burning sin, he left with the Forgetting Life Furnace. The cultivators of the Incense Valley were worried that the mysterious man would cut down the grass and eradicate the roots, so they fled. Of course, there is a third version. Some people speculate that in fact, the pill was not refined that night, but because the pill was too rebellious, so it touched the cause and effect that could not be resisted, including the burning sin, the mysterious man, and everyone in the Burning Incense Valley, all because they were contaminated with cause and effect, so they were ruthlessly wiped out by the will of the Heavenly Dao. In the face of different opinions, the truth remains a mystery to this day. Jie recalled the many rumors he had heard in the Immortal Realm, and explained to Ling Yu.

Seeing Ling Yu's thoughtful expression, Jie shook his head, a deep gaze appeared in his eyes, and said to Ling Yu: "However, now that the Incense Valley has appeared here, I'm afraid that the truth of the matter will soon surface!"
