The sky is yang, and the earth is yin.

The fire of heaven and earth does not refer to a kind of flame between heaven and earth, but refers to the power of two kinds of fire from the high level of heaven and earth.

The fire of yang and the fire of yin are also the powers that can only be accessed by refining the void realm!

And Mingxin, even Tang Ling, wasn't sure what kind of fire Ye Feng had summoned!

Mingxin suddenly threw out so many cultivation secrets, and Ye Feng was stunned when he heard it, and he found his ignorance more and more.

Taking over this spirit box, Ye Feng couldn't help but be curious about the source crystal in this box and the abundance of source qi, you must know that this is a level that can only be reached by refining the virtual realm!

The source qi inside the source crystal was indeed invisible until the monk came into contact with the secret of refining the void realm, and Ye Feng was no exception.

However, according to some characteristics of the source crystal, the human monk let the source qi in the source crystal naturally overflow, so as to obtain the source qi in advance!

Sealing the spirit box, this is a magic weapon that can isolate the flow of spiritual energy and even source qi inside and outside. In the interior of this magic weapon, the source crystal and the broken spirit stone are sealed together, and the spiritual energy that overflows from the spirit stone will be reduced to the source gas by the source crystal after a long period of contact and reaction of the source crystal, and will be deposited at the bottom of the spirit sealing box!

However, such a simple and small method is actually only known by the core disciples of the three major sects in the East China Sea.

And this is the terrible monopoly of knowledge!

Since Ye Feng and Mingxin did not have a high-grade spirit stone on their bodies, Mingxin, who placed the fragments of the medium-grade spirit stone in them, could not determine the effect of this source qi reduction.

You must know that the gap between the medium-grade spirit stone and the high-grade spirit stone alone is a hundredfold, and the high-grade spirit stone also has some spiritual qualities that the medium-grade spirit stone does not have!

Looking at the spirit sealing box in his hand, Ye Feng didn't know if he should open it now to study this so-called source qi.

You must know that once this spirit box is opened, then no matter whether it is successful or not, the spirit stones consumed this time cannot be restored!

Considering that his current condition is not in the best state, Ye Feng also shook his head, let Mingxin put away this precious spirit sealing box, or open it again after a while!

With the return of the origin of spiritual power and spiritual power, Ye Feng became more and more familiar with the flames similar to the soul heart in the Purple Mansion.

The energy contained in the Flame Soul Heart could only be used to release resonance fluctuations, but under this resonance fluctuation, Ye Feng's ability to control aura and aura energy reached an extremely high level. Although this level is a little worse than the resonance of the origin of spiritual power, it is much more powerful than directly using soul jade.

At the same time, Ye Feng found that the flames generated by the continuous resonance fluctuations of the flame soul heart could be mixed with magic, greatly increasing the power of magic, but it was extremely difficult to make magic merge into this flame, and it would take an extremely long time!

However, the most rare thing is that this Flame Soul Heart will not interfere with the casting of other attribute magic, which makes Ye Feng extremely satisfied!

After the last battle of the Wooden Sword Cultivator, Ye Feng knew that the magic he mastered was too monotonous to meet the battles of various situations, so this time, after Ye Feng obtained the Flame Soul Heart, he immediately developed other varieties of magic.

Following the fireball, the heterogeneous magic of the fireball such as the Firebird and the Rocket was quickly mastered by Ye Feng, and then Ye Feng began to study the advanced fireball technique!

For example, condense a large amount of aura energy into a huge and stable fireball, and the moment the fireball breaks, a large amount of high-heat energy inside will turn into a blazing flame, causing a large area of fire damage around the target!

For another example, ten times the amount of aura energy of a fireball is filled into a shell made of fire-attribute aura, which is then compressed. When compressed to the extreme, the energy in the fireball is highly condensed, and it will produce a kind of change, which will transform into a violent and fiery explosion.

This fireball is extremely unstable, detonating the furious flames in it in an instant, causing a violent explosion and sputtering a large amount of flying flames!

However, this kind of magic could not satisfy Ye Feng, because he knew that although his magic was powerful, it was just ordinary aura energy magic, and above the aura energy, there was a higher sublimation and high-level power!

To tell the truth, Ming Xin and the others were stunned when they saw that the magic in Ye Feng's hand was changing day by day, and in the end, they were dumbfounded. If they hadn't seen it with their own eyes, they wouldn't have believed that there were such people in this world.

On this day, Ye Feng had a new trick, blowing up a beautiful meadow into a thousand holes, and some of the craters even went deep into the ground several meters deep.

Although Mingxin and the others had long been surprised by this, seeing Ye Feng's depressed expression of disappointment due to the failure of the experiment, the three of them felt that this world was indeed an unfair world, full of great malice!

A spell of Mingxin, from beginner to proficient, often takes months of hard cultivation, and this is still a relatively simple spell.

But, what about Ye Feng's guy?

In the blink of an eye, magic can be changed in a different way, and it is more powerful, this guy is completely self-taught!

However, if Mingxin said what was in his heart, I am afraid that he would only get Ye Feng a wry smile.

If he can learn without a teacher, then the experience of his previous life will live to that of a dog.

For the surprise that these three people showed from time to time, Ye Feng was also surprised, in order to live better, and in order to better protect his companions, Ye Feng needed stronger strength!

Summing up today's harvest, Ye Feng had to put down the development of the Flame Burst Arrow, although this magic combines the depth attack of the rocket and the breadth attack of the Flame Burst, but the two are really difficult to reconcile, at least with Ye Feng's current spiritual power origin and the power of the Flame Soul Heart, it is still too difficult!

However, when researching this, Ye Feng found that it was a good transition magic to turn the explosion into a crescent moon.

The crescent-shaped shape is very much in line with the principles of mechanics, and the crescent-shaped shape can also hit the depths of the target to a certain extent, and most importantly, this magic is easy to cast!

Now, the biggest constraint on Ye Feng is the only factor left in the magic power!

Although with the assistance of the Flame Soul Heart, Ye Feng's fire magic has greatly increased in terms of efficiency, greatly reducing the consumption of mana, but in the case of losing the soul jade, Ye Feng's magic power can be used a little less.

Seeing the Xiaoice Wind Bird at Nangong Qian's feet, which is also changing day by day, the relationship between her and it is really a thousand miles a day, and that kind of intimate interaction makes people all kinds of envy and jealousy!

"In that case, you can only do it!" Ye Feng said secretly in his heart, ready to start a plan that he had been hesitating for a long time!

Maybe it was because he saw Ye Feng's terrible, maybe it was because Ye Feng had the flame aura that he hated, although the hatred index of the Xiaoice Wind Bird for Ye Feng had skyrocketed during this time, it was no longer like before, and he couldn't give Ye Feng a look at his face at every turn.

However, the more it reined, the more Ye Feng was afraid of it, lest he would accidentally be pecked to death by a bird beak by this insidious little guy that day!

However, after Ye Feng returned to normal, the happiest person had to be Tang Yu, a foodie.

Although Ye Feng can't easily use magic to cook, Ye Feng himself has good skills, plus he has prepared all kinds of condiments, which can well satisfy his appetite as a foodie!

And when it comes to this appetite, I have to say that demon beasts are really edible, well, they have been able to eat since childhood!

A small chick, its food consumption is not much worse than Tang Yu. Moreover, these two little guys also have the mentality of competing in this field, one eats more than the other, and no one lets anyone.

If it weren't for the fact that this place was far away from Howling Wind City, and the surrounding game resources were sufficient, it would be easy to satisfy the appetite of these two little guys, otherwise Ye Feng would not be able to satisfy them even if he roasted himself.

And now, Ye Feng can only hope that these two guys can restrain their appetite the next time they enter the big city, otherwise their wallets will not be able to bear it!

You know, where they are going next, there are many places to use money!

Ye Feng, who was driving in person, looked at the smoke rising not far away, Ye Feng's spiritual power was slightly released, and he soon found that there were people hunting in the woods.

It's just that due to the lack of the increase of the soul jade, and the fact that the origin of the spiritual power has not recovered, this perception distance makes Ye Feng feel very unaccustomed!

Perhaps because of the imminent departure from the Izumo Mountains, horse-drawn carriages and pedestrians can be seen on this stretch of the road.

In order to avoid trouble, Ye Feng had to let Mingxin and Nangong Qian stay in the carriage, trying not to show their faces, and as for the Xiaoice Wind Bird, which looked more and more like an ice wind bird, it was ordered by Ye Feng not to go out.

Since the people of the Kong family have not tracked it down to this point, they can't expose the matter and attract the attention of the Kong family!
