Fuedan, as its name suggests, is a mixed blessing and misfortune, and it may be blessed after taking it, or it may be directly abolished, and this probability accounts for half of each. If it is successful, the cultivation will soar without being restricted by the realm barrier, but if it fails, the cultivation will be completely ruined, and there is no room for reversal.

So when refining this elixir, Su Yu hesitated and couldn't make up his mind. If you talk about the benefits, the Fu Er Pill is definitely a hundred times stronger than the Blood Building Pill! Because no matter how much you take the Blood Building Pill, you must personally try to break through it and break through the barriers, and all that can be brought to you is the maximum amount of Qi and Blood and True Qi.

But Fu Erdan is different, ignoring the barrier and sweeping all the way, soaring like a rocket! This is definitely a great help to the current combat power of Su Yu's side!

But all the people on his side are friends and relatives, not puppets, even if they are puppets, under maintaining a high degree of independent thinking, they have been getting along for a long time, for Su Yu, they are no longer tools, but their friends and relatives!

So no matter what, Su Yu didn't want them to take any risks for themselves to bear that half of the destruction.

"Or ...... Let's practice the Blood Pill, although it is a little close, but at least it is safe enough......"

Thinking like this, Su Yu gave up refining the Fu Er Pill and instead refined the Spirit Building Pill. That's right, it's to practice the spirit pill first, and then practice the blood pill.

Because in that thundercloud storm, although Su Yu absorbed a little power of the dragon-shaped spirit vein, it was just a drop in the bucket, and the rest of the entire dragon was all taken in by Shennong Ding.

In other words, now the entire spiritual vein is in the Shennong Ding, and it is preserved as a material for refining the spirit pill. Although Su Yu also tried to extract this spiritual vein little by little, but it was too thick, and he sadly found that Shennong Ding seemed to be only in and out.

If the materials go in, they can only be taken out after refining the elixir, otherwise they can't be taken out at all. This really made Su Yu embarrassed! After all, it was a whole spiritual vein, wouldn't it be better if it was absorbed little by little? The Spirit Pill was ranked as the highest level of elixir in the Dan Sutra, God knows how terrifying it was!

But now that it has been accepted as a material, if you don't refine the Spirit Pill, it will be useless at all. Therefore, even if Su Yu was a little reluctant, he still put the materials needed for refining the spirit pill into the Shennong Ding step by step, and then the rules of fire controlled the fire attribute spiritual power in the body to form flames, and he was engrossed in refining the spirit pill.

Before this, Su Yu also discovered a magical place in Shennong Ding, that is, although Shennong Ding can only refine one pill at a time, the rest of the collected materials can be stored separately, and when refining the pill, it will not cause any harm to other materials at all.

This point is very similar to the Qiankun bag, as if there is a subspace, and they do not interfere with each other. This made Su Yu worry a lot.

Therefore, at this moment, Su Yu was engrossed in refining the Spirit Pill, and he didn't think about the whale kings who existed in the space isolated from Shennong Ding like the small fish fry. Anyway, if they are made to be water, they can't die.

The elixir, as the name suggests, is to build spirits for cultivators, provide a source of spiritual power to the greatest extent, and use medicinal materials to maximize the effect. And according to the records of the Dan Sutra, this spirit pill can definitely be called against the sky!

Because there is no limit to the medicine or things that contain the aura of heaven and earth in this elixir, there is no limit to the size, strength or weakness. In other words, even if you have a branch that contains spiritual energy, you can refine it into a spirit pill, and if you have a mountain range that contains the spiritual energy of heaven and earth, you can still refine it into a spirit building pill.

But although they are all elixirs, the medicinal effects are different. Nonsense, can the aura contained in a tree branch and a mountain range be the same?

Of course, this anti-heaven is more manifested in the materials required. For example, this dragon-shaped spiritual vein in Su Yu Shennong Ding now, not to mention how much heaven and earth spiritual energy is contained here, the volume of this giant dragon alone is really surprising!

Have you ever seen a dragon? Have you ever seen a giant dragon with a body of 100 feet and a length of 1,000 feet? Zhun Bao has never seen it! And this dragon-shaped spirit vein happens to be the real reason for the formation of the thundercloud storm!

A thunderbolt can make the true yuan powerhouse fly ashes and annihilate, do you say horror is not terrifying?

It is also thanks to Shennong Ding that he is against the sky enough, otherwise, if Su Yu wants to obtain such a great creation, it will be a fool's dream at all! No, he is not even an idiot, at most he is a fool two hundred and five!

Thinking of this, Su Yu couldn't help but sweat profusely, and he was afraid! Because at that time, he was an ambitious leopard who dared to swallow this spiritual vein like swallowing the innate fire spirit!

Thanks to the fact that he didn't succeed at the time, if he really devoured this spiritual vein, he would obediently bang loudly, it would not be a thundercloud storm explosion, but he Su Yu would directly turn into a firework!

But fortunately, at this time, the spiritual vein has been included in the Shennong Ding, although it cannot be directly devoured and absorbed, but this does not prevent Su Yu from extracting part of this spiritual vein to refine the spirit pill.

Of course, it can only be a part, after all, although there are many medicinal materials in Su Yu's bag, it is not a medicine warehouse in the whole world. It would be good to be able to meet one-tenth of the compatibility of that spiritual vein!

After putting all the medicinal materials into Shennong Ding, Su Yu used all his divine sense and spiritual yuan power to control the flame and refine the pill day and night.

It wasn't until seven seven and forty-nine days later that this Spirit Pill-building Pill was completely released! And when it came to refining pills, I had never heard of refining only one pill in one furnace, so this time the Spirit Pills refined by Su Yu were indeed quite numerous, and they had reached one hundred!

Looking at the refined Soul Pill, and then at the Whale King of the Sea of Darkness that was isolated like a small fish fry in Shennongding, Su Yu didn't say a word, he directly picked up a Soul Pill and swallowed it.

This time, he is using himself as a medicine test boy, and groping for his aunt and grandmother to take the spirit pill in the future, this is the second time, the power of the spirit yuan in Su Yu's body is really lacking, and it is almost the end of the day, where is the extra ability time to refine other pills?

With the entrance of a spirit pill, Su Yu suddenly felt that the whole person was like a boiling kettle, his whole body was hot with red, and his limbs and veins seemed to be filled with countless scorching steam!

However, it was the spirit pill that melted in the mouth, directly rushing into Su Yu's limbs and veins, nourishing the meridians lacking spiritual power, and mobilizing the circulation of the spiritual power power in his whole body.

And the Spirit Building Pill was refined with the spiritual vein as medicine, although it was only one hundredth of tenth, but the spiritual power was also absolutely abundant! So the moment it entered Su Yu's body, it exerted a miraculous effect.

However, Su Yu is also a virtual realm cultivator now, and a Spirit Pill will not be of great help to him, but this does not prevent this Spirit Pill from directly replenishing one-third of the spirit yuan power that he lacks all over his body!

Not only that, but the Spirit Building Pill seems to have a miraculous effect that has not been recorded in the Dan Sutra, that is, when it enters the body circulation, it actually impacts Su Yu's meridians intentionally or unintentionally, making Su Yu's meridians become wider and more flexible within a certain range!

Although it is only a little bit, it is just this little bit, for every cultivator, it is definitely what every cultivator wants! Because the width of the meridians directly determines the strength in a person's body, as well as the strength of the moves issued.

So when he saw this scene, Su Yu didn't say a word, and directly put the two spirit pills directly into his mouth. It didn't take long for the spiritual qi deficit in the body to be completely replenished, and there seemed to be a situation of overflowing! Not to mention the meridians, although they were subtle, they were still a little wider.

"This Spirit Pill is so awesome, I don't know if I will ...... if I eat a few more" As he spoke, the famous Su Maniac directly took out ten Spirit Building Pills and threw them directly into his mouth!

In the next few days, this space is simply a ghost crying wolf! Rao is Su Daxia Su Shen Doctor's concentration is amazing, but he can't resist the crisis of dying from explosion that does not exist all the time.

"Damn! It's too big to play now! It's too big! I knew how many I would eat less!" Su Yu, who was infinitely hard, desperately suppressed the spiritual power in his body, and seemed to be crazy and compressed inward.

It wasn't until half a month later that Su Daxia's body, which swelled like a balloon every day, went soft, and then the whole person also went soft.

Three days later, Su Daxia, who was crazy and didn't want to die, sat up slowly with palpitations, looked at the guy under his belly and navel, and said fearfully: "I'm, I'm almost dead." This Nima is terrifying......"

"Huh, it seems that this cultivation is a little wrong...... Ouch my god! Wealth and wealth are in danger, and it is really true, thirteen spirit pills have actually sent my buddies directly to the middle stage of the Void Realm! Although it is only the middle stage, it is indeed the middle stage!"

Su Daxia, who was inexplicably excited, naturally didn't know at this time that the reason why he was able to break through was because of the cheap spiritual vein. You must know that at that time, this spiritual vein was surrounded by a time storm, a space storm, and some thunder and lightning powers, and the power of wind and clouds.

If these forces exist, there must be such rules. And Shennong Ding didn't pay attention, so he also included these storm powers, and then this mysterious Shennong Ding can no longer be mysterious, refining the spirit pill, naturally contains a trace of the power of these rules.

Although it is a very small number, the breakthrough of the virtual realm is the mastery of the rules. Being able to master another rule, no matter how many, has actually reached the standard of breaking through the Void Realm. As for the follow-up mastery, it is necessary to continue to study the rules and master more in the process of becoming stronger step by step.

There is a saying: Master leads the door to practice in an individual, although it is a bit far-fetched, but I have to say that this is actually an opportunity, as long as you have this opportunity, you can step into the next realm, it is just an open door, whether you can be strong in the future, it depends on yourself.

At this moment, Su Yu is like this, although the shit luck has crossed the early stage of the virtual realm and reached the middle stage, but the power of these rules still needs his continuous research and control to be able to continue to improve.

How far this road is, no one knows. In ancient times, some people spent their lives without gaining a single star, but there were also people who hit the next realm again within a month. The rules of heaven and earth are so mysterious......
