Soon, Xia Yun took away the twelve Shi Saint King Spirit Cores and handed them to Du Yunyun, anyway, it was useless for him to keep them.

Although Xia Yun was very curious about who Du Yunyun's master was, he was so frightened that the evil fire forgot to take these twelve Shi Saint King Spirit Cores, but he still didn't ask much, anyway, sooner or later he would have a chance to see it.

"Where are we going?"

After Du Yunyun put away those Saint King Spirit Cores, she asked curiously, she can't go back to the sect, she can only cultivate in the world.

"Soul River. ”

Xia Yun said without hesitation: "If we encounter a little trouble, we haven't finished collecting the Revenant Soul Flower, and it is also very suitable for our cultivation." ”

He became a junior true martial spirit king, facing those earth king beast souls, he was no longer so afraid, although there would be heavenly king spirit beasts from time to time, but with the vision of the blood moon god eyes as a warning, the possibility of encountering heavenly king spirit beasts was basically none.

"Good. ”

Du Yunyun naturally didn't have any objections, thought of something, and said, "This is your outer door identity card." ”

As she spoke, she handed Xia Yun an identity tag.

"Uh......"

Seeing this, Xia Yun couldn't help but feel embarrassed, he didn't expect that someone would make use of this outer disciple identity card, and then took it and put it away, saying, "It's better to change your clothes." After a pause, "Do you have any other clothes?"

"Yes. ”

Du Yunyun nodded, naturally knowing what Xia Yun meant, since he was going to take refuge now, he definitely couldn't wear the clothes of a disciple of the Northern Spirit Sect.

"You turn around first. ”

With that, she took out the clothes she was usually wearing.

Ten minutes later.

High in the sky, the scorching sun wind soared into the sky, flying in the direction of the Soul River.

Xia Yun and Du Yunyun sat on the back of the scorching sun wind peng, resting well, especially Xia Yun, he didn't expect that he would rush from the Shen Soul River to the Yin Wind Ridge in less than half a day, it was really incredible, if he was asked to do it again, he found that he couldn't do it to this extent.

With the extreme speed of the Scorching Sun Wind Peng, it would take four days to get to the Soul River.

At this time, Xia Yun remembered that there had been a change in the Moon Spirit Space.

"Except for the True King Spirit Core, they are all fused in an instant to form ......"

Xia Yun noticed that there were only two kinds of spirit cores left in the Moon Spirit Space, the True King Spirit Core and the Holy Spirit Core, and the time to fuse the True King Spirit Core was so fast that he was extremely surprised, it only took one month, and it took half a year to fuse the Holy Spirit Core at the beginning.

The position of the Moon Spirit Space Fusion Core has more than doubled from four hundred to one thousand, and Xia Yun is naturally even happier.

Thinking of the number of beast souls that the Black Hole Spirit needed to fuse, Xia Yun couldn't help but feel that fusing a thousand True King Spirit Cores in a month was really not too much.

Xia Yun carefully tested it, when the spirit of the black hole fused the soul of the true king, every ten days of acceleration, it needed to consume a true king spirit core, and the spirit of the black hole fused a true king beast soul, it took two hundred days, and once the acceleration was instantaneously fused, it would take twenty true king spirit cores.

The Black Hole Spirit needs a total of 2,000 True King Beast Souls to grow from infancy to adulthood, and it definitely needs to be accelerated, which requires 40,000 True King Spirit Cores.

Xia Yun almost scolded, but he really lived up to the name of "black hole".

He counted the spirit cores in the Moon Spirit Space, there were more than fourteen thousand True King Spirit Cores, plus those that were still being fused, there were more than 15,000 in total, and the Holy Spirit Core had about 30,000 pieces, which could be fused to create more than 3,000 True King Spirit Cores.

Xia Yun's space bag also has about 10,000 True King Spirit Cores.

All of them combined, he probably had less than 30,000 True King Spirit Cores, which seemed like a lot, but it was not enough to cultivate the Black Hole Spirit to adulthood.

The road is still far away!

Fortunately, there are not so many demon spirits and magic spirits, otherwise, Xia Yun will never think about becoming stronger.

"The spirit of the black hole is so strong, it's still worth it. ”

Xia Yun had to comfort himself.

In fact, Xia Yun knew that the price of cultivating the spirit of the heavenly dragon was not small, although the resources for cultivating the demon spirit itself were not much, but the resources for cultivating the demon beast were very terrifying, and the resources required for each dominant dragon were astronomical, not to mention the rabbit that was more black than a black hole, and it was not less than cultivating the spirit of a black hole, and even more than that.

It was precisely because the martial spirits and demon spirits were frantically devouring Xia Yun's resources that he was about to forget the existence of the magic spirit, and basically used the praise of life to prove that he was still a magic spirit master.

As for the number and time of fusion souls, Xia Yun was most surprised, there were originally eighty, but only twenty were added, becoming one hundred, which was one percent of the number of fusion cores, but the fusion time was ridiculously fast, it only took ten days, and it took three months to fuse the Holy Spirit Beast Soul at the beginning.

When he learned these data, Xia Yun felt like he was dreaming, so he didn't have to worry about the lack of the source of the True King Beast Soul at all.

In a month, at least three hundred True King Beast Souls.

The fusion of the Holy Spirit Beast Soul is completed instantly, so in the Moon Spirit Space, there are only two kinds of Beast Souls, the True King Beast Soul and the Holy Spirit Beast Soul.

Neither the Earth King Beast Soul nor the Earth King Spirit Core could enter the Moon Spirit Space, and could only be temporarily stored in the Space Bag.

In a short period of time, Xia Yun no longer needed to worry about the problem of beast souls, and the current moon spirit space stored more than 30,000 Holy Spirit Beast Souls and more than 18,000 True King Beast Souls, which was enough for martial spirits, demon spirits, and magic spirits to grow to the stage of transformation.

Of course, Xia Yun was not satisfied with this, the Moon Spirit Space could now store 100,000 beast souls, and he couldn't waste it, which was why he went to the Soul River again, stockpiling more Holy Spirit Beast Souls and True King Beast Souls, just in case.

Once the Great Escape is made, it will be impossible to collect Beast Souls and Spirit Cores.

From the moment he took Du Yunyun to the Soul River, Xia Yun was ready to flee for his life, just like when he first came to the Four Spirits Continent.

"I wonder what kind of abilities the Blood Moon Divine Eyes will have?"

This is what Xia Yun is most concerned about.

"No?"

Soon, Xia Yun found that there was no change in the Moon Spirit Space and the Demon Spirit Space.

"Isn't that right?!"

Suddenly, Xia Yun realized that at some point, there was a new space next to the Moon Spirit Space, which was completely different from the Moon Spirit Space.

In the new space, a delicate alchemy furnace was suspended, all black and empty.

"Is it still possible to automate alchemy?"

Xia Yun was taken aback when he thought of this.

As soon as his mind moved, Xia Yun opened the alchemy furnace.

"Huh, there's a book?"

Xia Yun saw a very thin book placed in the alchemy furnace, with the words "Dan Linglu" written on it.

After that, Xia Yun turned the first page.

"True King Spirit Pill?"

Xia Yun couldn't help but be stunned, there were only four words "True King Spirit Pill" written on the first page, which occupied four-fifths of the page, worried that others would not see it.
