In the previous worlds, whether it was Murong Fu or Liu Bei, they were all silent, and they solved Yang Yun's identity lightly. Perfectly inherited the cause and effect and obsession of the other party.

And now, the Cause and Effect Divine Tree brutally killed Hei Jiao, this kind of behavior of killing others and making Yang Yun pretend to be his identity is a bit too irritable.

It's like the Cause and Effect Divine Tree is worried that others will find out, and wants to quickly solve Yang Yun's identity, and then hide it with all his might.

Yang Yun sighed, no matter what, let's check some of Heijiao's memories first and see the origin of this world. Hopefully it's a more familiar world.

He probed his mind into the soul of the black dragon, and pictures and memories appeared in front of his eyes. Yang Yun's face changed instantly, and his face was shocked.

"Beiju Luzhou, the stormy sea in the North Sea......!

This world is very similar to the ancient immortal world that Yang Yun knows, there are dragon kings of the four seas, as well as heaven and earth. The whole world is also divided into Dongsheng Shenzhou, West Niuhe Continent, South Ganbu Continent and North Julu Continent.

A very familiar name!

Yang Yun instantly thought of an unruly monkey!

"Could it be that this is the Journey to the West?"

Yang Yun muttered in his heart. After a moment, he forcibly lifted his mind and continued to retrieve Heijiao's memory. This black Jiao came from the sea area to which the Beihai Dragon Palace belonged. There is a true dragon blood in the body.

His father was also the famous Dragon King of the North Sea. However, this identity does not bring glory, but disdain and contempt. Hei Jiao has been cultivating in Beihai for hundreds of years, and he has not even cultivated the Yuan Shen. It is even regarded as a waste by many dragon princes in the Dragon Palace.

Hei Jiao was unwilling, and accidentally found an ancient ruin, so he resolutely went to this ruin to explore, hoping to find a treasure from the ruins that would change his fate.

He had endured a great deal of hardship in the ruins, and finally found an ancient truth.

If Yang Yun hadn't come to this world, this black Jiao might have been able to soar into the sky with this ancient true technique. Noble birth, wasted qualifications, and occasional acquisition of the true Fa, once soaring to the sky! This is the treatment of a person with strong luck.

"Nine changes of demon gods?"

Yang Yun found the ancient secret he had obtained from Hei Jiao's memory. As soon as the mind moved, tens of thousands of characters appeared in my mind.

"Nine changes of demon gods...... Absorb a drop of the demon god's essence blood, transform into a demon god through the transformation of the exercise, and have the powerful body and boundless supernatural power of the demon god! There is still this kind of exercise?"

Yang Yun gasped in his heart, and his eyes showed a hint of heat. This kind of exercise contains a strong ancient atmosphere, and it is obviously the supreme true secret handed down by the ancient great supernatural powers.

And this kind of exercise focuses on physical changes and simulations, and does not affect Yang Yun's foundation.

If he can practice, then Yang Yun's strength can rise rapidly, and he will directly become a strong party.

When he came into contact with the memories of the Black Jiao Divine Soul, Yang Yun also knew the reason why the Cause and Effect Divine Tree was so hasty. According to the message from the sacred tree. This world is too large, and it has already given birth to a strong person who can affect the operation of the Heavenly Dao.

Although the Cause and Effect Divine Tree was a supreme divine object, its power depended on Yang Yun's strength. In a world where there are no great supernatural powers, it can easily use cause and effect to blind the Heavenly Dao.

But here, if it were to use the original method again, it would be directly perceived by those great supernatural powers who could affect the operation of the Heavenly Dao. And the Cause and Effect Divine Tree can't be revealed in front of people, once Yang Yun is discovered by them, he can only be slaughtered at that time.

It is precisely because of this that after the Cause and Effect Divine Tree brought Yang Yun to this world, it did not be as gentle and silent as before, but found the closest creature with similar strength, killed it directly, and absorbed the cause and effect from the other party. Let Yang Yun replace the identity and cause and effect of the other party and appear in this world.

"The name of the black Jiao is...... Ao Xuan: Let me see what other obsessions it has!"

Yang Yun sighed secretly in his heart and continued to probe with his mind.

"Subvert the Beihai Dragon Palace!"

In the deepest part of the Black Jiao Divine Soul, the biggest obsession is this. Yang Yun's face suddenly looked a little strange. Black Dragon...... There is also the obsession of subverting the Dragon Palace.

Ao Xuan, wouldn't it be the Great Sage Jiao Demon King of the Journey to the West?

According to Yang Yun's knowledge, the Jiao Demon King only appeared once in the Journey to the West World, and never showed up again. And the Jiao Demon King ranked second when the Seven Great Sages formed a righteous alliance, which is enough to prove that he has great magical powers.

And the black Jiao at the moment has not even been cultivated as a primordial god! From this point of view, it is a bit different.

"It's also possible that it's the Jiao Demon King who hasn't grown up yet!"

Yang Yun thought wildly in his heart. After half a ring, he calmed his mind, urged his body, and found a cave in the mountains and forests of the island to settle down temporarily.

The most important thing now is to use the essence and blood soul of the black Jiao to cultivate the Nine Transformations of the Demon God, and mix his own breath with Ao Xuan, otherwise, if a strong immortal god notices him, he can detect that he, a pure-blooded human being, is not the same species as the original black dragon at all.

Ethnicity is different, but cause and effect and identity are exactly the same. That's the biggest flaw.

Fortunately, Ao Xuan got the Nine Transformations of the Demon God handed down by the ancient supernatural powers from the ruins. The essence blood of the black Jiao contains the blood of the true dragon.

The real dragon once dominated an era of antiquity. It's still on top of the ordinary demon god bloodline. It can be absorbed and refined by the Nine Transformations of the Demon God.

"The power of cause and effect helps me to comprehend the exercises!"

For this kind of ancient true secret, it is difficult for many immortal Dao powerhouses to comprehend. However, Yang Yun has the power of cause and effect, as long as there is enough consumption, he will naturally be able to succeed in comprehension with the assistance of this mysterious power.

Inside the cave.

Yang Yun's eyes were slightly closed, and as soon as his mind moved, the essence blood of the dragon appeared in front of him, this ball of essence blood exuded a faint bloody aura, this blood mass was the gathering of the essence of the dragon's body, and in the red blood, there was also this trace of golden light.

"Start refining!"

After exhausting all the power of cause and effect, Yang Yun had a deep understanding of the Nine Transformations of the Demon God, although he had not yet fully comprehended the exercises, but cultivation was no longer a problem.

Along with his thoughts, a trace of dragon essence blood still seeped into his body.

The nine changes of demon gods are not only nine demon gods. The meaning of nine is infinite, as long as there is time, energy, and enough demon god bloodline, even if it is a hundred changes and a thousand changes.

But a cultivator's energy is limited after all, and too much refining of the demon god's bloodline is simply useless, and it is purely a waste of time.

The best way is to find a demon god bloodline with enough potential, and then continue to tap the potential along this bloodline until you can exert the full strength of this demon god and be able to turn into an ancient demon god!

The Nine Transformations of the Demon God is like a bloodline evolution method.
