The two of them collected the Revenant Soul Flower, which was obviously a lot more efficient, but Xia Yun and Du Yunyun didn't dare to separate too far, and they wouldn't be more than a thousand meters apart.

It's night.

After most of the day's hard work, Xia Yun and Du Yunyun collected a total of ten Revenant Soul Flowers, which was many times more efficient than the one Xia Yun collected alone.

In this way, Xia Yun has nineteen Revenant Flowers, and it will not be a problem to complete the task.

While collecting the Revenant Soul Flower, Xia Yun and Du Yunyun also found a lot of precious elixirs, some of which were also the core elixirs for refining the Earth King Demon Pill, which made Xia Yun overjoyed.

The earth king spirit beasts on both sides of the Shen Soul River were crisscrossed, and Xia Yun and Du Yunyun could not avoid encountering the earth king spirit beasts, but they were slaughtered by the two of them, as many as ten.

At this time, on a sandy land about a kilometer away from the Soul River, Xia Yun and Du Yunyun camped on the spot, which was simply arrogant.

In fact, when the earth king spirit beasts in this area saw Xia Yun and Du Yunyun, they were so frightened that they ran away, otherwise those dead earth king spirit beasts would be their "role models".

Xia Yun was too ferocious, and he also carried a three-headed earth king spirit beast.

During this period, a Heavenly King Spirit Beast was discovered, but Xia Yun and Du Yunyun had already prepared and easily dodged it.

"You have a good night's rest. ”

Xia Yun pointed to the small tent not far away.

"What about you?"

Du Yunyun asked a little embarrassed.

"I'm keeping vigil and practicing martial arts by the way. ”

Xia Yun smiled slightly.

"Well, be careful, then. ”

After that, Du Yunyun got into the small tent.

Seeing this, Xia Yun sat cross-legged, closed his eyes, and began to practice the Earth King Martial Technique that Hu Wanwu had prepared for him-

Thunderball!

The attribute resonance of the black hole spirit is pitiful, there are only two kinds, one is the thunder attribute and the other is the empty attribute.

If Xia Yun wanted to exert the strongest power of the Black Hole Spirit, he could only cultivate the thunder attribute and void attribute martial arts, while Hu Wanwu only had this one that specialized in cultivating the thunder attribute aura.

Although Thunderball is an Earth King Martial Technique, as a single attribute spirit technique, its power is far stronger than that of a multi-attribute Heavenly King Martial Technique.

Therefore, the Heavenly King Martial Technique is not necessarily stronger than the Earth King Martial Technique, and the Demon Technique and the Technique also have such a situation.

In a sense, cultivating a single attribute will be more powerful, but the weakness is too obvious, as for how to choose, it depends on the individual's situation.

Xia Yun's Black Hole Spirit is too special, and cultivating a single attribute is the wisest choice, and he has a state martial skill like the Thunder Spirit Descending, which is the most suitable for cultivating Thunder Wanjun.

The cultivation of martial arts is to breathe, to put it bluntly, it is the way of breathing, inhaling aura, not only through the mouth and nose, but also through the skin, even hair, etc., and finally integrating the required aura into every part of the body, blood vessels, muscles, bones and nerves, etc., including the five internal organs, and exhaling unnecessary aura, which is called a week.

For example, the Thunder Wanjun, the Earth King Martial Technique, is to inhale the aura of heaven and earth, leave the thunder aura, integrate it into the body, and exhale the aura of other attributes.

The ultimate goal, no matter what you do, can carry out this process of vomiting, without deliberately doing it.

To do this, the only way to do this is through the accumulation of training, and eventually form a habit, or even instinct, so that the way of exhaling this martial technique is as natural as breathing.

The upper limit of the Diwang Martial Technique is twenty-four weeks, and within one day, the cycle is twenty-four times, and if it is done for six weeks, it can be regarded as an entry.

The upper limit of the Heavenly King Martial Technique is thirty-six Zhou Tian, and the efficiency is higher than that of the Earth King Martial Technique, but if it is a variety of attributes, it must be shared, because only one attribute of the aura can be integrated at a time.

For example, the Heavenly King Martial Technique of two attributes, Zhou Tian of one attribute is only eighteen, which is lower than twenty-four, so there is a saying that the Earth King Martial Technique of a single attribute is stronger than the Heavenly King Martial Technique of multiple attributes.

In addition to cultivating martial arts, Xia Yun planned to use his heart and soul to study the Danling space.

For Xia Yun, many things may be difficult, but it's good to get used to it, he has too many things to do, and the enemy is too strong, he must become strong as soon as possible in order to survive and protect his friends.

No, then learn more, think more, do more, and there will be a day when you will know.

In the Danling space, the pitch-black alchemy furnace was still hanging in the air, as if it was the center of this space.

After that, Xia Yun's mind opened the Dan Ling Record, found the Dan Fang of the Earth King Demon Pill, and according to the above materials, put the various elixirs in the space bag into the Dan Ling space.

At first, he was not familiar with it, but this step, Xia Yun spent more than an hour, there were many elixirs that he didn't know, so he could only identify them one by one, Du Yunyun also specially gave him a piece of jade called "Elixir Pharmacopoeia", which recorded all kinds of elixirs that humans know so far, otherwise, Xia Yun really didn't know how to identify those unfamiliar elixirs.

When the alchemy materials were all complete, before Xia Yun could react, those materials with more than thirty kinds of materials flew into the alchemy furnace that opened automatically.

"Whew!"

There was a muffled sound, and in the pitch-black alchemy furnace, a burst of fire shone brightly.

"That's it?"

Xia Yun didn't know anything about the alchemy furnace, and when he realized that he really didn't have to do anything, this magical alchemy furnace began to automatically refine the elixir.

"It seems like it will take three days......"

Xia Yun glanced at the Dan Fang of the Earth King Demon Pill, which said that it would take three days to refine.

"Three days, it's acceptable. ”

Xia Yun was not in a hurry, so he found the second elixir, the pill recipe of the Earth King Pill, and began to find out those elixirs.

Another hour passed.

"Two ...... Missing"

Xia Yun found that in order to refine a Diwang Pill, he also needed two precious elixirs, although they were not rare, but they were not easy to pick.

Without the Earth King Dan, it is impossible to become the Earth Spirit King, so Xia Yun naturally needs to prepare.

Although the growth of the Black Hole Spirit is not fast, the growth rate of the Heavenly Dragon Spirit, a first-class demon spirit, is very terrifying, especially since Xia Yun has a lot of resources, which is even more terrifying.

Xia Yun estimated that he would soon be able to become a junior Earth Demon Spirit King.

To become the Earth Demon Spirit King, in addition to one Earth King Pill, you also need to have five spirit beasts above the True King level, which is no problem for Xia Yun at all, and the True King Demon Spirit has grown to the transformation period, and this is only a matter of time, and Xia Yun can do it at any time.

Next, Xia Yun began to study other pill recipes again, so as not to know when he needed it.

He has one more thing, which is to study Danfang, so it is inevitable to use two things, otherwise he will not be able to squeeze out so much time.

"The road is still ......"

When Xia Yun thought that the manager of the Four Spirits Continent was a strong person at the level of a spirit immortal, he suddenly did not have the joy of obtaining the supreme treasure, but had a kind of indomitable determination and determination.

No one can stand in the way of his revenge!
