"Brother Qisheng, have you ever heard of Yin Yang Qianyu?"

Ye Fan suddenly asked.

"Yin and Yang Qianyu? What are you talking about is the mystery of Yin and Yang in the legend?"

Xu Qisheng recalled it, and suddenly reacted.

"Yes, it is it, it seems you know it!"

Ye Fan nodded slowly.

"It is mentioned in the inheritance of the ancestors that apart from practicing the Promise theory and fusing thousands of martial skills, the ancestors are looking for the Yin and Yang Qianyu in this life. Legend has it that the Yin and Yang Qianyu contains the extremely powerful technique of Yin and Yang. Unfortunately, the ancestors continued to die. I could not see Yin Yang Qianyu, so I think it is just a rumor!"

Xu Qisheng said with excitement.

"Yin and Yang Qianyu is not a rumor, it has always been located in the library of Shangrui Tianyu, and no one cares about it!"

Ye Fan couldn't help sighing when hearing Xu Qisheng's words.

"Really...really? In the memory of our ancestors, I always thought that the Secret Code of Yin and Yang Qianyu must be located in the Qianlong Tianyu. I didn't expect to be in the Shangrui Tianyu, no wonder..."

Xu Qisheng was a little unbelievable after hearing it, but felt that he realized the great ambition of the Emperor.

"Now the yin and yang Qianyu is on my body, and my yin and yang changes are derived from the Yin and Yang Qianyu!"

Ye Fan continued to explain.

"No wonder it is so powerful, Ye Fan, but... can you lend me a copy?"

Xu Qisheng stretched out his palm and asked.

"Look at it!"

With a wave of Ye Fan's sleeve, a huge book flew out of the blood.

This ancient book has a height of half a person, and the cover is made of black on one side and white on the other side. At this moment, it is emitting a light of black and white in the Jinluang Temple.

"What a strong yin and yang breath, is this the yin and yang Qianyu?"

Xu Qisheng looked at this ancient book, his eyes full of reverence.

"Brother Qisheng, have you ever heard of an old man named Tianwei?"

Ye Fan suddenly thought of something and asked.

"Old Tianwei? Didn't you hear?"

Xu Qisheng took his mind back from Yin and Yang Qianyu, slowly shook his head, and said in confusion:

"Do you want to find him?"

"He should no longer be in the void, but this Yin and Yang Qianyu was left by him, and he was also created by him!"

Ye Fan shook his head, didn't have such expectations, just explained.

"What? He created Yin and Yang Qianyu?"

Xu Qisheng was even more shocked after hearing it, and he couldn't believe it.

"The old man Tianwei once gave me some guidance in Tianwei Continent. The Yin Yang Qianyu's ability to reach my hands should also be related to him!"

Ye Fan slowly expressed his guess.

The ancestor of the Ye family and the old man Tianwei have always been mysterious to him.

"Unexpectedly, there are such high-level people in this world!"

Xu Qisheng did not doubt Ye Fan's words, but sighed with emotion.

"Returning to the topic, this yin and yang thousand imperialism records the three yin and yang techniques, in addition to the yin and yang bipolar transformation that I have already understood, there are also more advanced yin and yang infinite changes and yin and yang extreme changes!"

Ye Fan looked at Yin Yang Qianyu and slowly explained.

"Infinite change and extreme change! I didn't expect that there really is a deeper way of Yin and Yang!"

Xu Qisheng heard this, with yearning on his face, and at the same time he understood:

"In that case, my guess should be correct. Although your yin and yang changes are powerful, they can no longer support the evolution and fusion of the Sword of the Big Dipper and Chaoge Sijun. Infinite change or the power of endless change is needed. Combine two martial arts!"

"Indeed, the more powerful the martial arts, the higher the changes and requirements for the path of Yin and Yang. The Sword of the Beidou and the Four Jungles of Chaoge are not incapable of fusion, but a powerful path of Yin and Yang is needed!"

Ye Fan nodded slowly.

"Speaking of which, are you going to continue to practice the Yin and Yang Tao?"

Xu Qisheng tried to inquire.

"I can only do this. In the future, I might integrate more martial arts, and I must master a more powerful way of Yin and Yang!"

Ye Fan nodded heavily, and his eyes turned to Yin Yang Qianyu.

"That said, I want to practice with you!"

Xu Qisheng nodded and asked at the same time.

"No problem, just..."

Ye Fan immediately agreed, and at the same time showed a sense of sorrow.

"Just what?"

Xu Qisheng asked subconsciously.

"The path of Yin and Yang is extremely difficult to cultivate. Although we have the Yin and Yang Qianyu as a guide, it is still difficult to understand the infinite change or the extreme change in a short time. For fear that the Azure Cloud Realm King will suddenly be killed, then we will be particularly passive!"

Ye Fan expressed the worry in his heart.

Xu Qisheng fell silent for a while, as if lost in thought.

"It would be great if Mengli could wake up, so that we can practice the endless changes of Yin and Yang!"

Ye Fan continued to speak.

"Ye Fan, I know a quick way to practice Yin and Yang, but I don't know whether it is true or not!"

After Xu Qisheng pondered for a moment, he suddenly spoke.

"Oh? Say it!"

Ye Fan immediately lit up after hearing this, and asked.

"When my ancestors traveled through the void when they were young, they encountered a special plane. The plane was purely black and white, and contained sufficient power of yang and yang. The ancestors understood the magical transformation of yin and yang there. With the help of yin and yang, a method of combining martial skills was born, thus creating the theory of Promise!"

Xu Qisheng said slowly.

"That plane, are you still there?"

Ye Fan's expression became excited after hearing this, and he immediately asked.

"That plane was named the Land of Yin and Yang by the ancestors, and was later transferred to a special place by the ancestors!"

Xu Qisheng slowly explained.

"So, it's still there, do you know where it is?"

Ye Fan understood, his eyes became hot.

"Yes, this time it is in an artificial plane I created, where there is a Void Wanderer guarding it!"

Xu Qisheng smiled and nodded.

"You have protected these good places very well!"

Ye Fan also laughed.

"This is nature. The land of Yin and Yang is a treasure left by our ancestors. I know it will be of great use sooner or later, so I have always kept it properly!"

Xu Qisheng said with a hint of pride.

"It shouldn't be too late. Go to the land of Yin and Yang immediately. With the help of the Qian Yu of Yin and Yang, we can definitely comprehend a stronger way of Yin and Yang. By then, your strength will rise again!"

Ye Fan couldn't wait to say.

"Okay, you and I are ready to go, two days later!"

Xu Qisheng left the promise.

"Two days later, see or leave!"

Ye Fan nodded, the flame of hope rekindled in his eyes.

The failure of martial arts integration made him feel depressed, but now he saw hope again.

There is no harm to him to improve the power of Yin and Yang.

"Yin Yang Qianyu, this time I rely on you!"

After Xu Qisheng left, Ye Fan stepped down from a high position and stroked the Yin and Yang Qianyu Dao in the center of the hall.

"brush……"

Yin Yang Qianyu turned into black and white light, trembling slightly, and then Ye Fan took it back into his blood.
