Yang Yi has read too many novels and popular science about time and space shuttle, and the results caused by time and space shuttle are almost a few.

One is that he returned to the past and became a part of history. He went down the long river of time and one day he would come to the era before he traveled through time, see his predecessor, and find out the reason why Yun Ruochu disappeared.

But in this way, he must follow history completely and cannot make any changes. Every change may lead to drastic changes in later generations, and he and Yun Ruochu may be gone. If it changes, it will form a paradox of time and space.

However, in this case, there is another possibility that no matter how he changes, as long as it does not affect the general trend, every change he makes will become a part of history, and history will constantly correct itself and will not deviate from the established track.

Another thing is that when he returns to the past, time and space also change, creating a time and space parallel to the original time and space. The two move towards a different future, which means that he can change at will in the current prehistoric world. Even if he kills Hongjun, he will kill the six saints of the future, because Yun Ruochu is in another parallel time and space.

In fact, Yang Yi still had a question in his mind. Is the prehistoric myth in his memory true? And is this prehistoric world the prehistoric world in his memory?

Especially at this moment when he heard what Taoist Yangmei saw and heard, he felt absurd, and this prehistoric world was different.

For a moment, he was thinking and frowned, because every step from now on may affect the future time and space and Yun Ruochu's existence, so he could not be cautious.

"Fellow Taoist, what is the realm of this quasi-saint and saint? Has the fellow Taoist realized the Dharma and created a more complete system of immortal Taoism?"

Taoist Yangmei hesitated for a moment and asked. He was really curious. He knew that it was the fifth-level system in the immortal cultivation system created by Hongjun.

Judging from the fact that the Earth Immortal, Heavenly Immortal, Xuan Immortal, and Golden Immortal are the first to fourth levels, wouldn’t these quasi-saints and saints mean that they are the sixth and seventh levels that no one has reached yet?

Thinking of this, it makes you feel a little scared when you look up. If it is true, it will definitely subvert all the cognitions of the creatures in the prehistoric world.

"Quest Saint? Saint? Oh... it was not created by me, but I think the titles of the middle and late stages of the Daluo Golden Immortal are good, so there is such a saying." Yang Yi came back to his senses and could only say that. In fact, he and Yang Mei's guess were exactly the same. If this quasi-saint and saint also correspond to a unified system, they must be level six and level seven.

"So that's it." The Taoist Yangmei smiled, but there was still a hint of suspicion in his eyes. As Yang Yi said, it was reasonable and more in line with the current prehistoric practice status, but he still instinctively felt something was wrong.

"saint........"

Yang Yi heard the word "saint" on the side but also escaped from his anger. He felt like he was in a stubborn state.

No matter what the future is, what he can do now is to let things go, not to mention that as long as he achieves the saint's karma, he can investigate the three realms and six paths and know the past and present. At that time, no matter where Yun Ruochu is, even if he breaks the cycle of reincarnation and travels all over the heavens, he will find her out.

Now, for him, the most important thing is to create his own cultivation system and technique, and to achieve the saint as quickly as possible.

"Fellow Daoist Yangmei, I have a question and ask for answers. How can a monk determine how many levels of existence correspond to each realm of his cultivation system after he founded the path of cultivation? Is it just relying solely on power?" Yang Yi was puzzled, he had always existed.

"Haha, fellow Taoists don't know that after each cultivation system is established, the creator will burn incense and pray for the way of heaven and reap the merits of the way of heaven. This system is equivalent to entering the Heavenly List and can be used for endless living beings to practice."

"The corresponding level of this technique will be displayed in the Heavenly List, and this level classification is also the prayer of the creatures at the beginning of the creation of the world to be recognized by the Heavenly Way. Of course, the creators do not have to publicize their practice system on the Heavenly List. However, in this way, there will be no merits of the Heavenly Way, and it will be even more difficult to improve the subsequent practice of the creatures."

"In ancient times, the more creatures practiced in a certain cultivation system, the greater the benefits the system creators gained, and there are various indescribable uses. One of the statements is that this can help the fifth-level existence break into the supreme realm of the sixth-level."

He smiled kindly and said, not stingy about sharing what he has gained. He is a smart person and naturally knows how great it will be for him to make friends with a strong man transformed from the fifth-level original power.

"So that's the case, thank you for telling me." Yang Yi understood and stared at the Tongtian Divine Mountain in front of him.

"It's okay, this place is at the foot of Mount Buzhou. It is said that it was transformed by the spine of the great god Pangu, which contains infinite magic. Most system pioneers will come here to realize the Taoist body and method. fellow Taoists can also go to the mountain to practice." Yang Mei reminded.

He knew that Yang Yi had just transformed into shape. Although he had fifth-level power, he did not have the corresponding martial arts system support, and his power would inevitably be reduced a few times.

Even said that although Yang Mei is in the fourth level, if he fights against a fifth level power, he has a 99% chance of winning and can kill the opponent.

The two talked about the basic customs and common sense of the prehistoric land and strange stories, and finally said goodbye and left first.

Just because the divine light work on Buzhou Mountain a few days ago was suspected to have a treasure, he raised his eyebrows and rushed to Buzhou Mountain to seek opportunities. Unexpectedly, he met Yang Yi before he arrived on the mountain.

Yang Yi was invited to go with him in the middle of Yang Mei, but Yang Yi politely refused. He joked that he was a fifth-level expert in parallel. Now that he talked too much, he felt that too much would lead to mistakes, let alone fighting for treasures. He would definitely reveal his feelings at that time, so it would be better not to go.

Seeing Yang Mei leave, Yang Yi also got up and walked. He found a cave not far from the foot of the mountain, which was just enough to see the vast view of Buzhou Mountain.

"Buzhou, Buzhou, inherits the giant pillar of heaven." Yang Yi looked at this giant pillar and felt a unique, eternal and unyielding will. Is this unwillingness to Pangu's fall in the sky?

Gradually, his eyes became blurred, and his soul and the forehead were shining, causing him to enter a deeper state of enlightenment.

I don’t know how long it took, in a moment or countless years, when Yang Yi woke up again, he found that there was a piece of blue jade bi in his sea of ​​consciousness.

Yang Yi seemed to have expected it, and reached out and pointed at the jade bi.

"Pangu Xuan Gong?" His face looked strange. The name of this martial art was direct enough.

"Is it the original martial arts again?" Yang Yi rolled his eyes. This book was just like he had obtained more than 4,000 inheritances before. It was just that the teaching of how to create martial arts did not have specific content such as the Heart Art Realm.

"All of them are so virtuous." Yang Yi glanced at the four thousand starlights boredly, and suddenly became stunned. A crazy thought continued to rise in his soul.
