Within a few minutes, Xia Yun was full.

"It should take another two days to complete the fusion. ”

Xia Yun subconsciously glanced at the fusion of those mortal spirit beast souls in the eyes of the Blood Moon God, and estimated the time.

"Let's get out of here. ”

So, Xia Yun left quickly, staying in one place for too long, something would definitely happen.

Fortunately, Qiu Xue left Xia Yun a space bag, otherwise he might have carried a large bag of things on his back.

The space bag, although not too precious, is generally only affordable for earth spirit masters.

Qiu Xue left Xia Yun with three things, one was the space bag, the second was the blood moon god eyes, and the third was a demon beast.

Before she dissipated, she told Xia Yun to find Xiaoyue, which was the name of the demon beast.

......

I don't know how time has passed in my cultivation.

In the blink of an eye, two days passed.

During this time, Xia Yun had a rare quiet day, without encountering any killers, and not even seeing a single figure, which was also the situation he wanted the most.

Every day, Xia Yun would kill two true spirit beasts to obtain the beast soul and spirit core, and most of the time was spent looking for prey.

He must have some aura and physical strength left behind to deal with emergencies, so killing two true spirit beasts every day is already his limit.

On this day, in the lush grass.

Xia Yun sat on the ground, panting, habitually glanced at the situation in the eyes of the Blood Moon God, and found that those mortal spirit beast souls had finally been successfully fused.

"True Spirit Beast Soul?"

Xia Yun carefully looked at the spirit beast soul that had been successfully fused, and suddenly showed a look of surprise.

"Absorbed?!"

Before Xia Yun could react, the demon spirit absorbed the three true spirit beast souls inside.

"A real goblin?!"

When Xia Yun came back to his senses, he found that the demon spirit had advanced to the true demon spirit, and although it was still a round ball, it had turned gray and white, and it was the size of two fists.

"Can you really become a demon master?"

Xia Yun had an inexplicable expectation in his heart.

"Go in?"

Xia Yun's ghost made a difference, and his heart moved, allowing his true martial spirit to enter the eyes of the Blood Moon God.

"It can't be really, right?"

Xia Yun laughed out loud, and his true martial spirit appeared in the eyes of the Blood Moon God.

"The real demon spirit is here. ”

Xia Yun's mind moved again, and the true demon spirit disappeared into the eyes of the Blood Moon God.

"Sure enough......"

Xia Yun jumped up excitedly.

"Unfortunately, you can only use one ...... at a time"

Soon, Xia Yun calmed down, but he couldn't help but get excited in his heart.

"I don't know if I can absorb a magic spirit......

Xia Yun fantasized a little greedily, there was no way, he needed to become stronger, and he would try all the means that could become stronger.

"Don't be too greedy. ”

Xia Yun calmed down again.

"Let's catch the flying spirit beast first. ”

With a decision, Xia Yun quickly left.

Although the Blood Moon Divine Eyes made Xia Yun's field of vision as large as a kilometer, he felt that it was necessary to find his prey from a high altitude vision.

......

A month later.

10,000 meters in the air.

A huge black falcon, like a small plane, soars under the blue sky.

This is a Burning Sun Eagle, which is Xia Yun's demon beast, but it is a mortal spirit beast.

At this time, Xia Yunpan sat on the head of the Burning Sun Eagle, sharing the vision of the demon spirit, looking down on the deep mountains and dense forests below, looking for prey.

After a month of hard work, Xia Yun has successfully become an intermediate True Martial Spirit Master.

Now, Xia Yun can be regarded as figuring out what is going on in the space of the Blood Moon Divine Eyes.

Xia Yun temporarily named that magical space "Moon Spirit Space".

In the Moon Spirit Space, Xia Yun could only control two things, a martial spirit and a demon spirit, and those beast souls, he couldn't control them.

Even if they can control the martial spirits and demon spirits, they only have their access permissions, but they can't control what the two "spirits" do inside.

As long as the Blood Moon God Eye saw the moment the spirit beast died, it would take the initiative to suck its beast soul into the Moon Spirit Space, just like taking a photo.

In addition, the moment Xia Yun crushed the spirit core and caused the beast souls in it to emerge, the Blood Moon Divine Eye would also suck those beast souls into the Moon Spirit Space.

Once the beast soul enters the Moon Spirit Space, as long as the number meets the fusion rules, it will merge on its own.

Nine in one!

This is the conclusion that Xia Yun came to after a month of observation.

Nine mortal spirit beast souls fused into one true spirit beast soul.

Xia Yun tried to collect all nine true spirit beast souls, but he couldn't fuse them together to become earth spirit beast souls, it is estimated that this is related to his own cultivation, or the number of fusion rules has changed, and this point, he has no way to explore it for the time being, so he is too lazy to think too much, so he can only wait until he becomes an earth spirit master to study it.

The Moon Spirit space is very large, and Xia Yun estimated that at least a thousand beast souls can be stored.

Ever since he figured out this rule, Xia Yun began to consciously kill spirit beasts of all levels.

As for the time required for fusion, Xia Yun also probably figured it out.

It takes three days to fuse a true spirit beast soul.

The most critical ......

There can only be ten fusion souls in the Moon Spirit Space at the same time, but Xia Yun feels very satisfied, every three days, he steadily harvests ten true spirit beast souls, which is more efficient than killing true spirit beasts by himself, after all, it is not difficult to kill mortal spirit beasts.

Now, Xia Yun's True Martial Spirit and True Demon Spirit are already in adulthood, and in order to break through to the peak, they each need to absorb twenty True Spirit Beast Souls, a total of forty, if it was before, it would give him a headache.

When this batch of fusion souls is completed now, Xia Yun will be able to become a high-level true martial spirit master.

If there was no Moon Spirit Space, it would take at least a few months for him to become a high-level True Martial Spirit Master.

After a month of hard work, Xia Yun already possessed thousands of mortal spirit cores, and there were almost a hundred true spirit cores.

After becoming a high-level true spirit master, Xia Yun planned to go to the only town in this forest to exchange all the spirit cores for true spirit cores, and then exchange them for some precious elixirs and potions to strengthen his body.

The strength of the body is the foundation of the martial spirit master.

And those elixirs and potions that strengthen the body, known as the "Spirit Core Black Hole", are very expensive, and Xia Yun's current spirit core is definitely not enough.

The Mortal Spirit Core is one of the most cost-effective food ingredients for cultivating demon beasts.

Although Xia Yun had a scorching sun eagle, he couldn't consume so many mortal spirit cores at all.

As for wanting to avenge Qiu Xue in the Blood Killing Palace, Xia Yun planned to become a junior earth spirit master before thinking about it, after all, he knew that the Blood Killing Hall Master was a powerful junior earth spirit master, and there were many true spirit masters around him.

Meanwhile.

In the gloomy woods, a middle-aged man as burly as a bear quietly hid under a luxuriant tree, looking at Xia Yun's scorching eagle from afar.
