"My nephew said so. As an uncle, I will accept your great gift. Alas, it's a pity that what you need is the True Nether Spirit Liquid and the True Nether Spirit Stone. If it is the True Nether Spirit Qi,

If so, it will be easier to handle. Although the money I got from Guiyuan Cave is not much, I can still collect some." Dugu gave such a big gift, so Qi Heng naturally couldn't be stingy with the Zhen Mingzhi in Guiyuan Cave.

Angry, but it was really a pity that he had arrived. This was not what Dugu needed.

"The Qi of the True Netherworld." Dugu couldn't help but feel moved. He has the Netherworld Spirit Space and can compress the spiritual energy into liquid. "I just don't know, uncle, how much of the Qi of the True Netherworld is produced in your Guiyuan Cave?"

"Hey, I hear what you mean, that Zhenming Qi is also useful to you, my nephew?" Hearing Dugu's question, Qi Heng couldn't help but be overjoyed. If he could really help the other party, he would feel less indebted to others.

"Yes, to be honest with my uncle, my nephew has a space that can compress spiritual energy into liquid. I just don't know what the output of Zhenming's energy is in my uncle's Guiyuan Cave. If I extract it, will I be harmful to Qi Jiaming?

The pulse has some influence." Dugu said frankly.

"Oh, I really didn't expect that my nephew actually has such a magical power." After listening to Dugu's words, Qi Heng couldn't help but be surprised. In terms of the function of this ghost space, it is not too much to compare with a magical power, and I am afraid it will be compared to the magical power.

Most magical powers are far more useful.

"As for the True Ming Qi, well, let's put it this way. I think Wan'er has already told you that the True Ming Spiritual Qi in Guiyuan Cave accounts for about 30% of the Ming Qi. You only need to know that the amount of Ming Qi produced in the cave in one day is

The Qi is enough to fill up the Yuan Ding of a first- and seventh-level monk. As for the influence, it is nothing at all. These underworld Qi are continuously produced every day."

To fill the Yuan Cauldron of an ordinary seventh-level monk, the amount of spiritual liquid required is about three hundred kilograms. Three hundred kilograms of spiritual liquid contains 30% of the true spiritual liquid, of which at least sixty or seventy kilograms can be quenched.

Here comes the True Nether Spiritual Liquid. Based on this calculation, Dugu only needs two days at most to harvest a sufficient amount of True Netherworld Spiritual Liquid.

"Since my uncle said so, my nephew wants to give it a try. If he can really extract enough Zhenming Spiritual Liquid from Guiyuan Cave, he will reward him with three Spiritual Transformation Pills." This news,

Dugu was very excited.

"How can this happen? My nephew has already given me a lot of gifts, a little bit of Zhenming Qi, and if he still wants to receive payment, then my uncle will be really shameless." Qi Heng declined quickly.

Qi Heng firmly resigned, and Dugu didn't want to be strong, so he had to make up his mind to give the remaining pills to Qi Wan before leaving.

Looking at Dugu, Qi Heng thought for a moment, took out a jade bottle from his arms, handed it over, and said with a smile: "There is a fruit from the tree of death. To be honest, Wan'er asked for this thing before.

, I am really reluctant to part with it, and now it seems that I am stingy, so this fruit will be regarded as a return gift from my uncle, and my nephew must not refuse it."

Looking at the jade bottle handed over by Qi Heng, Dugu was really hesitant. He didn't know the purpose of this thing before, but now he understands that for the undead monks, it is a life-saving and healing holy medicine.

He could accept it easily.

"Uncle, please don't be busy." Dugu did not take the jade bottle, but asked. "As far as my nephew knows, this medicine can be used to make an elixir, and the effect after it is made into an elixir is better than the effect of taking it raw.

It may be a thousand times better, but I wonder if there is a recipe that uses this death fruit as the main medicine to refine an elixir with similar effects?"

"Well, there are some, but in millions of years, this elixir has never been seen in the world." Qi Heng pushed the jade bottle on the table in front of Dugu and replied, since the thing was given away, he naturally

There is no possibility of recovery.

"What's the reason? I think this kind of elixir is probably more valuable to the undead power than the soul-condensing elixir. Isn't there anyone who asks someone to refine it?" Dugu asked strangely.

.

"There must be some, but some of the medicinal materials needed for this elixir are produced in the human world and are extremely difficult to find. Moreover, it is extremely difficult to refine this elixir. It is said that life and death are in the same furnace. It is said that research has

The person who made the alchemy recipe was originally a human alchemy master. By chance, he became a life-and-death friend with a powerful person in the underworld.

It was because he saw that his friend's physical body was damaged and it was difficult to repair it even with the power of the fruit of the Tree of Death, that he decided to research this elixir and tried every possible means to refine the elixir to help his old friend recover.

The body, but later, when I tried to refine it, I never succeeded. This shows how difficult it is." Qi Heng shook his head and smiled bitterly.

"After that, in order to commemorate the friendship between the two of them, the great power of the dead got this elixir recipe from an old friend and kept it. After that, it slowly spread in the underworld, and many great powers got the elixir recipe.

I also tried to refine it, but to no avail."

As he spoke, Qi Heng took out an animal skin from his storage ring, handed it to Dugu and said with a smile: "People always think that they will be the lucky ones that God pays special attention to. When I was young, I didn't

Exception, I also spent a lot of effort to find this prescription, but now it seems that I am still young and arrogant."

Dugu took the prescription written on the animal skin and read it carefully. Only then did he understand what it means to live and die in the same furnace.

This elixir is really ingenious. As we all know, the two qi of life and death are incompatible. For living beings, the qi of death is the most powerful poison. For undead souls, the same is true for the qi of life.

Above this pill, there are two kinds of medicinal materials, one of which is one of life and one death. The dead material is naturally the fruit of the tree of death, while the raw material is the core of the tree of life.

This was the first time that Dugu saw the core of the life fruit used as medicine in a prescription. But the pulp of the death fruit was used.

This elixir is introduced in great detail, and it also explains this point. It is called Born in the Heart and Dies in the Form, which is quite vivid. This elixir also has a name, which is called the Life and Death elixir. Its effect is better than that of death.

The fruit is tens of millions of times more effective for undead monks, and it also has the function of allowing its body to have a certain ability to regenerate and recover just like the human body.

Difficult, of course it is difficult. From Dugu's understanding of elixirs, it is almost impossible to refine elixirs with these two medicinal materials. It is necessary to control the elixir fire.

To an extremely subtle degree, I think that the alchemist who researched this elixir may have accidentally entered a strange state while caring about the safety of his old friend, just like the state of human unity that day, in order to be able to use it.

This elixir is made.

"Haha, my dear nephew, don't worry about this matter. In fact, for the undead monks, the fruit of the tree of death is only effective after taking it twice. No matter how much it is taken, it will be useless.

In fact, it’s easy to figure it out. In the cycle of heaven, there are those who are immortal and immortal, and the undead have a longer lifespan than the living ones. It is also appropriate that the body cannot recover from injuries." Qi Heng sighed.

Seeing that the other party really would not take back the death fruit, Dugu had no choice but to put it away. However, he remembered that the soul-condensing pill only used the pulp of the death fruit. In this way, he could use the pulp to refine it.

The core of the soul condensing pill can be used to cultivate spirit trees. Come to think of it, the value of several soul condensing pills is far higher than that of the death fruit.

Thinking this way, he felt at ease accepting the fruit of the tree of death.

"By the way, uncle, my nephew has one more thing to ask. In our vast world, there can only be one tree of life. I guess this tree of death is the same, but for some reason, in this true underworld,

Among them, there is a tree of death in every realm. Furthermore, if this tree of death is to be cultivated, what are the requirements?" Dugu carefully asked for advice.

"Oh, why did my nephew ask about this? Do you want to cultivate the tree of death in the underworld of your vast world? If you really have this intention, I think you'd better give up this idea.

The tree of death is just as you said, similar to the tree of life. No matter how big a world is, it can only contain one tree. But this tree of death is different from the tree of life.

In the final analysis, the Great Thousand World was created from its world foundation. Even though there is a small underworld built in it, its basic nature remains unchanged, so the Tree of Life can be cultivated.

But if you want to cultivate the tree of death, it is different. You must have a self-circulating underworld rule system that is not affected by external rules. Those small underworlds in the vast world are developed on its basis. It is not easy to avoid being affected.

, because of this, it is impossible to cultivate the tree of death.

In this true Netherworld, the only reason why there is a tree of death in every realm is because, in ancient times, several heavenly beauties once joined forces and spent trillions of years to find six nines.

The stone of the step-down boundary divides the entire True Nether Realm into six major realms. Each realm is like an underworld with independent rules. This makes it possible for several trees of death to be cultivated at the same time.

"

"Ah." When Qi Heng said this, Dugu couldn't help but exclaim softly.

"Why, my nephew felt the difficulty." Qi Heng naturally didn't know that Dugu had such a reaction after hearing about the boundary stone. He also said that he felt it was difficult and that's why he acted like this.

"This is not over yet. It is said that this ninth-level boundary stone is so rare that it is almost invisible, and the thing that cultivates the growth of the tree of death is even more rare. I also heard this when I participated in the Dao Fruit Conference of the Corpse God King.

When the God King talked about this secret, he realized that it is said that cultivating the tree of death not only requires the true five elements to help it advance, but also needs an even rarer thing before it has sprouted.
