"It seems that raising demon beasts is not cheap......"

Thinking that he had three spirits, Xia Yun had to have a headache, and it was obvious that the resources couldn't keep up.

Cultivating the martial spirit alone stretched his resources.

After that, Xia Yun tidied up his space bag a little, and found that there were only more than a hundred earth spirit cores now, and there was still a lot of gap between two hundred.

"Let's take the reward for the head of the middle school competition first. ”

Xia Yun soon had a plan, and now that he was an intermediate Earth Spirit Master, he would no longer have such a hard time facing a high-level Earth Spirit Master.

In order for an adult earth martial spirit to grow to its peak, it needs to fuse thirty earth spirit beast souls, one for three days, and it will take ninety days.

In this way, it would take at least three months for Xia Yun to become a high-level Earth Martial Spirit Master.

"I wonder if the Moon Spirit Space can be accelerated?"

Suddenly, Xia Yun thought that the martial spirits in the transformation period were all fused with beast souls in an instant, so he didn't know if the normal fusion would speed up a little.

He also knew that the fusion of the earth martial spirit soul in his infancy with the earth spirit beast soul had not accelerated, but he didn't know why, he suddenly had such an expectation.

"You can't speed it up for no reason......"

Xia Yun had a flash of inspiration, and there was a trace of thought in his heart.

After that, he took out an earth spirit core and stared at it for a long time.

"It's finished?"

Xia Yun was stunned for a moment, the earth spirit core in his hand disappeared, and he entered the moon spirit space.

"Not enough?"

Xia Yun found that the Earth Spirit Core did not react, and the Earth Spirit in the Fusion Beast Soul did not react either.

"Three-in-one?"

Soon, Xia Yun thought that transformation and fusion were all "three-in-one" rules, so he took out two earth spirit cores and inhaled them into the moon spirit space in the blink of an eye.

"Got it?!"

At the moment when there were three Earth Spirit Cores in the Moon Spirit Space, the Earth Martial Spirit finally changed, and the fusion was completed instantly, and the price was that the three Earth Spirit Cores disappeared.

"It can't really be like that, right?"

Xia Yun was a little excited.

"Gotta find a way to get a little more Earth Spirit Core back. ”

The plan in Xia Yun's heart changed again.

"There's no hurry. ”

After that, Xia Yun thought about it carefully, it would take at least a month and a half to absorb three bottles of nerve strengthening elixirs, so there was no need for him to grow the Earth Martial Spirit to its peak at once for the time being.

The Moon Spirit Space was able to fuse enough Earth Spirit Beast Souls on its own, and Xia Yun naturally wouldn't worry about the lack of Earth Spirit Beast Souls like others.

As for the spirit core, there is no other way for the time being, but to hunt the earth spirit beast.

"Next month's tour may be an opportunity. ”

Xia Yun made a decision again.

He is so short of the Earth Spirit Core!

......

It's night.

Xia Yun finally rushed back to the camp of the Fifth Middle Regiment, and the others had already rested.

"I wonder if the spirit core can be fused?"

Suddenly, Xia Yun had a strange idea again.

Soon, Xia Yun returned to his room, took out a bunch of mortal spirit cores and true spirit cores, tested them, and determined the conditions for the Blood Moon God Eye to inhale spirit cores, which required his body to be in contact, like the palm of his hand, so that the range was a bit small.

After that, Xia Yun sucked ten mortal spirit cores into the moon spirit space.

"Haha......"

Xia Yun suddenly laughed, he didn't expect that the spirit core, like the beast soul, could be fused by itself in the moon spirit space, or the rule of "nine in one".

"Developed!"

Xia Yun jumped up excitedly.

Next, Xia Yun put all the mortal spirit cores into the moon spirit space, and one after another fusion cores appeared in his sight.

"Huh, only a hundred?"

Xia Yun soon discovered that the fusion core, like the fusion soul, had an upper limit.

"In this way, it is still mainly fused into the earth spirit core. ”

Xia Yun quickly estimated, it was obviously impossible to fuse all of them into earth spirit cores, it was impossible for him to get such a large number of true spirit cores for a while, and it would cost nine hundred to fuse them once.

"One more question......"

Soon, Xia Yun noticed that the spirit core could only enter and not leave, which gave him a little headache, so it was impossible to put the spirit core indefinitely to fuse.

"Perhaps, when I get stronger, there should be other changes in the Blood Moon Divine Eyes......"

Xia Yun couldn't help but guess.

He didn't know anything about the Blood Moon Divine Eyes, not even Qiu Xue.

He had to explore and explore the Blood Moon Divine Eyes on his own, and for now, Xia Yun was still very satisfied.

People can't be too greedy, otherwise they are prone to accidents.

Next, Xia Yun only needs to wait for the success of the fusion core, deduce how long it will take to fuse the true spirit core, and then test how long it will take to fuse the earth spirit core.

What he lacks most now is the earth spirit core, although it can't be taken out, it can accelerate the fusion of the earth spirit spirit beast soul, which is of great significance.

Since he could fuse the Earth Spirit Core by himself, Xia Yun didn't need to provide additional Earth Spirit Core to accelerate the growth of the Earth Martial Spirit.

"Rest early, tomorrow is the qualifiers, you can't relax. ”

So, Xia Yun went to take a shower first, and then had a good night's rest.

......

Meanwhile.

The Du family's mansion.

in a secret room.

Du Dazhuang looked at the young woman in front of him in disbelief and said, "You said that the shadow was killed?"

"Yes. ”

The young woman nodded.

"How did you die?"

Du Dazhuang clenched his fists, the Dark Moon Mercenary Group was a force he had cultivated at a huge cost, and dying made him very distressed, especially an assassin like Shadow Kill, which was particularly rare.

"Punched to death. ”

The young woman recalled the image from the shadow kill, and said, "Just one punch, it's very domineering." ”

"A punch?"

Du Dazhuang slowly let go of his fist, only to realize that he had underestimated Xia Yun again.

"For the time being, no one can move Xia Yun. ”

Soon, Du Dazhuang made a decision.

"Huh?"

The young woman didn't quite understand.

"You want to be the next Shadow Killer?"

Du Dazhuang suddenly stared at the young woman and said, "I was careless this time, I don't want any of you to die." ”

The young woman was silent.

"Also, don't think about using beauty tricks, it's useless to Xia Yun. ”

Du Dazhuang thought of something and admonished.

"Useless?"

The young woman was clearly not convinced.

"You haven't seen him. ”

Du Dazhuang thought for a moment and said, "His eyes don't have normal human nature. ”

"Huh?"

The young woman felt that Du Dazhuang was exaggerating.

"People like Xia Yun are terrifying. ”

Du Dazhuang added.

The young woman chose to remain silent.

"Let's go back. ”

Du Dazhuang waved his hand and said, "I will give you an explanation for the matter of shadow killing." ”

"Yes. ”

So the young woman turned and left.

"Xia Yun?"

Du Dazhuang sneered, the person he wants to kill will definitely die.

......

Following.

It's not dawn yet.

The vast school field was already full of people, making the quiet morning lively.
