The ghost mother's eyes suddenly widened, and she was shocked to see the changes in the ghost world.

Not only the ghost mother was shocked, but all the creatures in the ghost world were shocked, and Tian Yunshuang and Yun Ruoqing were also shocked.

This method of deriving the world is simply miraculous, and people dare not imagine it.

Especially the creatures of the ghost world, originally they thought that they and others would live forever in a world without sky and earth, but they didn't expect that this world would also give birth to sky and earth.

Under Su Yuan's control, mountains rose from the ground, and rivers meandered and circled.

A blood moon and a blood sun appeared in the sky, both embedded in the space-time interlayer.

Even Su Yuan evolved white clouds, plants and trees, and all things in heaven and earth.

But all this is just the appearance, the complete essence of these heavens and earths is still ghostly, but because of the rules of the ghost world, it looks very real.

The fruits of the plants and trees here can also be eaten, of course, only the creatures of the ghost world can eat them, and ordinary people in the human world can die if they eat one.

The rocks here can also be carved out to build houses, and this is a real world.

Although everything here is illusory relative to the human and celestial realms, these are real in relation to this world.

However, it is not completely illusory, when the creatures of this world are strong enough to a certain extent, such as the transcendent realm, they can enter the human realm and the heavenly realm, survive in the human realm and the heavenly realm, and be able to adapt to the rules of the other two realms.

It's like a powerful ghost in folklore that can move under the sun.

Soon, the evolution of the ghost world ended, and Su Yuan also stopped.

"This ...... This ......"

The ghost mother looked at the ghost world at this time, and was speechless, which was completely beyond her imagination, this was simply a miracle like a creation god.

Originally, she still thought that there were other ghosts to accompany her, and there were ghosts everywhere, it was an environment she liked, even if there was no sky and earth, she could accept it, and it could be regarded as heaven.

But compared to now, the previous environment was simply a prison, and now it is heaven.

At this time, there is almost no difference between it and the human world, there are also flowers and trees, heaven and earth, mountains and rivers, blue sky and white clouds, and the sun and moon.

The only difference is that because the essence of this place is ghostly energy, it is more and more blood-colored with the sun, and the sky is slightly gray, not as bright as the human world.

But it's already pretty good.

"This ghost world, as long as there are more and more ghosts in the future, after the ghost qi becomes more, it will automatically expand, and it will become bigger and bigger, so don't worry about not being able to accommodate more ghosts. ”

Su Yuan looked at the ghost mother and said, "But the ugly words are ahead, this function may cause the rulers of the ghost world to want to expand the world, so as to invade the human world and kill living beings, so I will block the ghost world, and only a few people, or special circumstances, can enter and exit the ghost world." ”

"I'm okay with that. The ghost mother agreed without hesitation, anyway, there is not much difference between this place and the human world, and she is not too nostalgic for the human world, and it is the same if she can't get out.

"As a thank you for sending the entire ghost world to you, it's not too much to give me another unit of cause and effect, right?" Su Yuan said with a smile.

When the ghost mother heard this, she frowned slightly, a little hesitant.

"What? Could it be that the value of the ghost realm is not comparable to the cause and effect of a unit?" Su Yuan wondered.

"Not really. "The ghost mother said tangled, "I told you before, I am the embodiment of cause and effect, cause and effect is my origin, although I can absorb the cause and effect between heaven and earth and grow, but it will not be too fast, this will hurt my roots." ”

"Is that so?"

Su Yuan was a little distressed, it didn't matter if he had other attributes, as long as he was willing to spend time, he could still get it.

But the causal attribute seems to be completely dependent on luck, and it is also against the luck of the sky, which can be obtained, and it is almost rare to have the time attribute.

So if you want to get the causal attribute in a short period of time, you can only start from the ghost mother.

The ghost mother did not bow her head, although the man in front of her seemed to have become the master of the three realms of the earth, she was not so afraid.

"Then let's do it, I'll give you another benefit, which can be regarded as exchanging a cause and effect with you. ”

Su Yuan said, and put his hand on the book of life and death again.

But this time, it's not about perfecting the ghost world, but about transforming the book of life and death.

This kind of transformation can be regarded as necessary, and by the way, it will earn a cause and effect, and it will not be a loss anyway.

You can't always let the book of life and death be here to transform ghosts, right?

The book of life and death in myths and legends is not the root of transforming ghosts, but only a treasure that controls life and death.

And he can't control life and death, he doesn't want to make this book of life and death as magical as in myths and legends, but at least he must be able to move, right?

After research and analysis, Su Yuan planned to disassemble the function of the Book of Life and Death.

There are three main functions of the Book of Life and Death, one of which is the most fundamental transformation of ghosts.

One is the roster of ghosts, as long as you become a ghost, your name will appear in the book of life and death, and the function of this roster is the ability to control the life and death of these ghosts.

The last one, which has been demonstrated before, is to control the ghost world, but it seems that only he can master this function.

After three days of research, Su Yuan refined and separated the function of transforming ghosts.

In the past three days, the Ghost Mother, Yun Ruoqing and the others have not left, they are all looking at Su Yuan.

Finally, on this day, they found that above the book of life and death, a gray-white vortex rose.

The whirlpool grew larger and larger, and finally turned into a huge whirlpool ten meters in diameter.

"Buzz!"

After the vortex is formed, it merges with the ghost world and cannot move.

And the book of life and death has been able to move and was put away by Su Yuan.

At this time, the book of life and death no longer has the function of transforming ghosts, only the function of controlling ghosts and controlling the ghost world of the roster remains.

Su Yuan Shennian held the book of life and death and sent it to the ghost mother, "The current book of life and death can control the life and death of all ghosts in the ghost world, so you are not more worried that the strength of other ghosts is too strong to control." ”

When the ghost mother heard this, a smile finally appeared on her beautiful face, although she thought that her cultivation speed should not be too slow and not surpassed, but who would dare to pack a ticket for this kind of thing?

Just like the guy in front of him, he was so much weaker than himself when he met last time, but this time he met, he was already above him.

Being able to control the life and death of the ghosts of the entire ghost world is definitely an unimaginable right, and this is the real control of one realm.

So the ghost mother was no longer entangled, and separated a unit of cause and effect from her body and gave it to Su Yuan.

One unit of cause and effect is equivalent to the smallest unit of cause and effect that Su Yuan could pick up when he first woke up, and it was no longer possible to break it up.

'Causal Attribute +1'

Su Yuan stretched out his right hand, and it was easy to turn this causal power into an attribute, and he suddenly smiled.

This time, he plans to use this cause and effect to create a causal weapon of his own.

Speaking of which, he doesn't really have a weapon in his hand, and the previous Yuan Light Sword was only made on a whim, in order to match the Yuan Light Sword.

But the weapon I really liked, I didn't.

"By the way, give me the book of life and death again, I have to open a door to the ghost world, otherwise even you won't be able to get out in the future. Su Yuan suddenly remembered something and said again.

The ghost mother didn't suspect it, and returned the book of life and death to Su Yuan.
