Honghuang: I was expelled from the Dragon Clan when I advised Zulong to go into seclusion.

Ao Yin closed his eyes tightly, and followed the method given by the system, and began to fuse the first Dinghai Shenzhu carefully and cautiously.

Since it was fused in the Dantian, there were still some risks in theory.

Therefore, Ao Yin did not dare to be careless.

Fortunately, the method given by the system was very complete. With Ao Yin's current strength, the possibility of failure was not high.

Five hundred years passed in a flash.

In the past five hundred years, although the process was very smooth, Ao Yin's spirit was highly tense!

Fearing omissions!

His pressure was beyond imagination!

Fortunately, the result was good.

He successfully fused the first Dinghai Shenzhu!

Ao Yin felt the cave world in his body and smiled with relief.

His five hundred years of hard work were worth it!

While checking the cave world, he recovered his severely exhausted spirit.

"The space of this cave world is a little small..."

Ao Yin sighed slightly.

He calculated that the size of a cave world was about the same as five hundred earths.

It sounds big, but compared with the prehistoric world, it is as small as a speck of dust.

After seeing the vastness of the prehistoric world, the cave world is a little unattractive...

What makes Ao Yin feel helpless is that there is nothing in the cave world except the endless sea water!

There are no sun, moon, stars, mountains, rivers, lakes, flowers, birds, plants, beasts and birds...

It is a bit of an exaggeration to say that it is a small world!

This is at most a semi-finished product!

If you want to perfect it into a real small world, you still need to put in some effort!

At this time, the small world can only provide Ao Yin with some spiritual energy!

Ao Yin is equivalent to having an additional spiritual energy reserve of a cave world!

It is useful, but not much.

But Ao Yin also understands.

He had expected this.

After all, he didn't care about the improvement in the early stage.

He valued the future of this method more!

If one day, when he carries a big world in his body, he will be invincible!

So, it doesn't matter if it doesn't provide him with much combat power in the early stage.

Ao Yin gathered his mind and stopped paying attention to the cave world. Instead, he closed his eyes and began to recover his mental strength.

His consumption in the past five hundred years was really too great.

He planned to rest for a while, and then start to refine the second Dinghai Divine Pearl after his condition was restored to the peak.

And his rest lasted nearly a hundred years.

Of course, he did not just close his eyes to rest during this hundred years.

While integrating the Dinghai Pearl, wasn't it also a training of the spirit?

Ao Yin found that when his mental strength was restored, it was much stronger than before!

More condensed!

Of course, he couldn't waste this benefit!

So he planned to take this opportunity to comprehend a magical power specializing in mental strength!

This was the first time he tried to create a magical power, and he had no idea whether he could succeed.

But fortunately, he had plenty of time to try and make mistakes.

...

The hundred years of rest passed quickly.

Ao Yin immediately took out the second Dinghai Pearl and refined it.

This time, he was more handy and at ease.

The operation was no different from the first time.

…

There is no time limit for cultivation, and no years for the prehistoric times.

Six thousand years passed in a flash.

In the quiet room.

Ao Yin opened his eyes and exhaled slowly.

His spiritual sense swept through his body, and he saw the twelve cave worlds suspended in his dantian, and he breathed a sigh of relief.

Finally completed this huge project.

The next step is to perfect it step by step.

However, this step cannot be rushed, it will be a long process.

"Over the years, under such high-intensity training, my mental power has been greatly improved, and I have made some progress in the mental attack method...

Maybe I can retreat for a while and comprehend it in one go!"

After making a decision in his heart, Ao Yin no longer hesitated and entered the retreat state again.

Three thousand years are like flowing water, passing in a flash.

On this day, Ao Yin, who had been in retreat for nine thousand years, finally ended his retreat and walked out of the quiet room.

He walked casually in the dojo.

At this moment, he looked very comfortable.

He came to a pavilion.

He brewed a pot of meditation tea for himself.

While sipping tea, he recalled his gains in the past three thousand years.

As expected, he created the spiritual attack magic.

But there is no experimental subject, so he is not sure about the specific power for the time being.

However, according to his vision, once hit by this magic, even the Golden Immortal will not feel good!

Ao Yin named this magic "Soul-Falling Cone"!

The name of the magic can tell its effect and form.

The consciousness turns into a cone, and the cone pierces the soul!

"If there is an experimental subject..."

Ao Yin muttered to himself with regret.

However, he soon put away this regret.

Next is Hongjun's preaching.

The powerful people from all sides will appear on the stage.

This means that the prehistoric world will prosper.

And prosperity will bring disputes!

In the world of great disputes, no one can be immune.

Ao Yin knew that it would not be long before this magic would come in handy.

After sipping tea, Ao Yin continued to walk in the dojo.

But this time, he had a purpose.

The Twelve Caves need to be improved.

There are currently three ways to improve it.

One is to inject the law into it,

The second is to inject the origin of the energy into it.

The third is to put innate spiritual objects into it to decompose the cave.

Ao Yin currently only has mastered five laws, which is the top number among the Golden Immortals, but it is insignificant for the evolutionary world.

The origin of the energy is very rare and scarce, and at the same time it is extremely precious. It is not easy to get it!

Speaking of the origin of the energy, Ao Yin first thought of the twelve ancestors of witches!

The twelve ancestors of witches were transformed from Pangu's blood and were born to master the laws. They must have the origin of the energy!

Ao Yin immediately made up his mind. After listening to the lecture, he immediately went to the witch clan!

After all, he helped the ancestor witch Hou Tu, so it should not be difficult.

And what Ao Yin can do for the time being is the third method-putting innate spiritual objects into it!

Although there are not many innate spiritual objects on Penglai Island, there are still some. For Ao Yin, there is no use for keeping them, so he threw them all into the Twelve Caves.

As for the innate spiritual treasures?

Although he has a few that he can't use, it would be a waste if he uses them here.

After all, the number of innate spiritual treasures is fixed, and one less is one less!

And its role is very important and indispensable!

…

After putting all the innate spiritual objects that can't be used into the cave world, some changes have also occurred inside.

It seems that something is brewing...

After watching for a while, Ao Yin stopped paying attention.

He calculated the time, and it was only a few hundred years before Hongjun preached.

Therefore, he didn't delay any more and immediately set off to fly towards the chaos.
