It's night.

Xia Yun chatted with Catalpa for a while, and then returned to his original room.

"The First True King Body has finally been formed. ”

Xia Yunpan sat on the wooden bed, feeling the changes in his body, and couldn't help laughing.

"You should be able to break through to the junior True Martial Spirit King. ”

Xia Yun thought expectantly, so he took out the three True King Beast Souls and fused them with the Holy Martial Spirit.

"Huh, isn't that right?"

Xia Yun obviously saw the Holy Martial Spirit fusing the three True King Beast Souls, but he didn't react at all, this shouldn't be.

"What's wrong?"

Xia Yun seriously recalled every detail and found that there was nothing wrong, what was the problem.

"Not enough beast souls?"

This was the only thing Xia Yun could think of.

"Try it. ”

As a result, Xia Yun fused the remaining three True King Beast Souls with the Holy Martial Spirits.

Outcome......

There was still no change in the Holy Martial Spirit.

Xia Yun was silent.

He had seen the process of Du Yunyun becoming the True Art Spirit King, so he didn't think that there would be anything wrong with his breakthrough process and details.

Xia Yun believes that the place where the problem is not the process is by no means.

"Black Hole Spirit?"

Suddenly, Xia Yun remembered something that the ancestor of the Du family had said, his martial spirit had a name.

"Black holes?"

When Xia Yun thought of this, an indescribable bad premonition surged in his heart.

"It can't be true, right?"

The more Xia Yun thought about it, the more he felt that this was the case.

The Holy Martial Spirit could not transform into a True King Martial Spirit, because the number of fused True King Beast Souls was not enough.

Under normal circumstances, only three beast souls are needed, which is also what the ancestor of the Du family told him, and Du Yunyun's holy magic spirit is transformed into a true king magic spirit, and only three true king beast souls are fused.

"No! I can't sleep if I don't figure it out!"

So, Xia Yun left Hongdu and went to Tianhong Ancient Forest, a hundred kilometers away.

There, there are a large number of True King Spirit Beasts.

A hundred kilometers, for Xia Yun now, is only a matter of ten minutes.

Xia Yun rode the wind speed Yan Lion, and at full speed, in less than ten minutes, he successfully came to the Tianhong Ancient Forest, which was a hundred kilometers away from Hongdu.

But at this moment, the wind speed is as tired as a dog, and he is lying on the ground and will not move.

Seeing this, Xia Yun had a hint of apology in his eyes, so he withdrew the Wind Speed Flame Lion to the demon spirit space, and then walked alone in the dark ancient forest.

There are still three days to go, and Xia Yun is not in a hurry.

Considering a high-level True Martial Spirit King like Han Tao, Xia Yun planned to break through to the junior True Martial Spirit King, and he would have a better chance of killing the Four Princes and Han Tao.

Although the Red Flame Holy Dragon was very powerful, Xia Yun died, and he died.

As a martial spirit master, Xia Yun naturally knew the strength of the martial spirit master, so Han Tao's strength was self-evident.

For the fastest efficiency, Xia Yun couldn't take care of it so much, as soon as he saw the True King Spirit Beast, he directly summoned the Red Flame Holy Dragon and the Phantom Ethereal Spirit Rabbit, and the two cooperated, basically killing the ordinary True King Spirit Beast in seconds.

Before you know it, the day passes.

With the help of the vision provided by the scorching sun wind peng, Xia Yun frantically harvested the True King Spirit Beasts in this area, basically killing two heads per hour, and at the end of the day, he had obtained more than fifty True King Beast Souls.

"Finally something has changed......

When the Holy Martial Spirit fused fifty True King Beast Souls, this Martial Spirit known as the "Black Hole Spirit" finally had a little bit of change.

That's right, just a little bit-

The colorful brilliance became more brilliant, like a light bulb going from twenty watts to forty watts.

Thinking of this, Xia Yun finally understood the true meaning of the spirit of the black hole being the weakest.

This simply can't transform into a true king martial spirit.

And the strongest is obviously to be felt only by transforming into a true king martial spirit.

"Go on!"

Embarking on this road, Xia Yun has no reason to give up.

At this time, Xia Yun had already penetrated three hundred kilometers into the Tianhong Ancient Forest, and the True King Spirit Beasts he encountered were becoming more and more powerful.

In order to restore the aura of the Red Flame Holy Dragon and the Phantom Ethereal Spirit Rabbit as soon as possible, Xia Yun directly let these two demon beasts devour the True King Spirit Core.

With the help of the Blood Moon Divine Eyes, the Red Flame Holy Dragon and the Phantom Ethereal Spirit Rabbit instantly devoured the True King's Spirit Core and restored their aura.

Although it is said that killing the True King Spirit Beast to get a lot of True King Spirit Cores, but in general, it is impossible to make ends meet, and the original remaining more than seven hundred True King Spirit Cores are now less than five hundred, and they can last for two days, but as the True King Spirit Beasts encountered become stronger and stronger, the spiritual energy consumption of the Chiyan Holy Dragon and the Phantom Ethereal Spirit Rabbit is also increasing.

Xia Yun estimated that there were less than five hundred True King Spirit Cores left, and they would only last for one day at most.

In the blink of an eye, a day passed.

The True King Spirit Core on Xia Yun's body was finally consumed, and the True King Beast Soul that was exchanged for it was only seventy.

In the end, the Holy Martial Spirit fused seventy True King Beast Souls, and there was still only a slight change, just like a forty-watt light bulb turning into a hundred-watt.

"What the hell!"

Xia Yun couldn't help but look up to the sky and yelled.

After carefully calculating, his Holy Martial Spirit had already fused a full one hundred and thirty True King Beast Souls, and he still couldn't transform into a True King Martial Spirit.

This feeling can no longer be described as hopeless.

If it weren't for the fact that he had the Blood Moon Divine Eyes, not to mention more than a hundred True King Beast Souls, it would be good to be able to get three, and under normal circumstances, it would take three days to fuse a True King Beast Soul, which was what Du Yunyun told Xia Yun, so it would take more than a year to fuse more than a hundred True King Beast Souls.

The most critical ......

Xia Yun no longer had the True King Spirit Core to restore the aura of the Red Flame Holy Dragon and the Phantom Ethereal Spirit Rabbit, so the efficiency of harvesting the True King Beast Soul would be even lower in the future.

Tomorrow is the day when the four princes ascend the throne and become emperors.

Obviously, Xia Yun had no time to become a junior True Martial Spirit King.

"It's really the spirit of the 'black hole'!"

Xia Yun looked up at the starry sky and had to complain about his martial spirit, the word "black hole" emphasized it even more, it is really a bottomless pit.

As for how many True King Beast Souls he still needed, Xia Yun didn't know, the only thing he could do was to constantly satisfy this bottomless pit of "Black Hole Spirits".

"I can only go back first. ”

Soon, Xia Yun had a decision.

Now, he has never seen the Holy Spirit Beast, obviously, in this ancient forest, there is only the True King Spirit Beast, if he continues to go deeper, Xia Yun is worried that he will encounter the Earth King Spirit Beast, at that time, it is really possible to call the heaven and the earth not to be spiritual, and he will die a miserable death.

So, Xia Yun stood directly on the head of the Red Flame Holy Dragon and broke through the air.

"Huh?"

Before it could fly out for a few miles, the Red Flame Holy Dragon stopped, stood suspended in the air, and stared at the thunderclouds that were gathering rapidly in front of him, from a radius of tens of meters to a radius of hundreds of meters, which was very terrifying.

Xia Yun stood vigilantly on the head of the Red Flame Holy Dragon, and his brows couldn't help but furrow.

Although the thundercloud was only 10,000 meters away from him, he found that the Blood Moon Divine Eye could not see through the thundercloud, which was very weird.
