"Brother, I'm back."

Li Youyun returned to Laifu Inn with a red face. When he saw Ye Xuan and Huang pangzi, he quickly handed the two meat buns in his luggage to them.

"Where did Youyun get the money to buy food?" Ye Xuan pretended not to understand.

"Listen to me, brothers."

Soon, Li Youyun told the story of today, and ye Xuan and Huang pangzi naturally knew what was going on, but they still lamented.

"Hey."

"The good younger brother was originally a scholar, but he made a public appearance for both of us. It's true, which makes us very ashamed." Ye Xuan scolded himself a little.

"Brother, eat the food quickly. Without the care of the two brothers, I'm afraid Youyun has already died on the way, and the two brothers' great kindness Youyun will never forget." Li Youyun spoke sincerely.

"You Yun, you said that the childe who promised you ten thousand liang of silver, isn't he really a liar?" Fat Huang said meaningfully.

"No, this young man is decent. He should come from a famous family and be a scholar. He won't lie to me." Li Youyun affirmed.

"Well, apart from that, I have something for you today. I should leave and leave." Ye Xuan whispered.

"What?"

Hearing that ye Xuan and Huang pangzi were leaving, Li Youyun looked stunned and hurriedly said, "where are the two brothers going? Don't you accompany Youyun?"

"There is no feast that never ends. It's time for us to leave. If it's fate, maybe we'll see you again."

Ye Xuan said, took out a scripture from his arms, and then handed it to Li Youyun: "this Scripture is not a Book of sages, but just a method of health preservation. Your body is weak. If you can understand this method of health preservation, you can prolong your life in the future."

Li Youyun took the Scripture in a daze. He opened the first page blankly, and a whisper came from his mouth.

"Wanzhang red dust method?"

"Yes, this Scripture is called the ten thousand feet red dust method. There are nine places for health preservation. If you can understand the first thing, it will be the day of our goodbye." Ye Xuan smiled and said.

"Don't worry, brother. Youyun will study hard and will certainly live up to your brother's expectations." Li Youyun solemnly collected the ten thousand feet red dust law.

At this point.

The yellow fat man's eyelids suddenly jumped and his eyes flashed a surprised color. He didn't think of it. Ye Xuan unexpectedly let Li Youyun understand the ten thousand feet of red dust method.

The ten thousand feet red dust method is Luo Xuan's thing. This method goes hand in hand with the immortal Sutra. In those years, ye Xuan and Luo Xuan exchanged scriptures. Huang pangzi witnessed this with his own eyes.

Normally, ye Xuan should understand this precious Scripture by himself, but why did he pass the ten thousand feet of the world of mortals to Li Youyun today?

I can't figure it out, and I don't understand it. A big question breeds in Huang Pang's heart.

"Ten thousand feet of mortal world, nine difficulties are coming. Youyun, you should take care of yourself."

Ye Xuan wandered out of Laifu Inn, but when he left, his words were unpredictable, and Huang pangzi quickly followed Ye Xuan. Only Li Youyun was stunned and speechless with the Scriptures. When he returned to his mind, ye Xuan and Huang pangzi disappeared.

"Ten thousand feet of red dust, nine difficulties?"

Li Youyun whispered to himself, with a look of confusion in his eyes. Obviously, he couldn't understand the meaning of this sentence.

In the void, there is no shadow.

Ye Xuan sat in the void. Fat Huang stood beside him, but a mirror image of heaven and earth appeared in front of them. Li Youyun's every move was also noticed by them.

"Sir, why are you..."

"You want to ask me why I passed the ten thousand feet red dust law to him?" Ye Xuan smiled.

"Hey, hey." The fat yellow man flattered with a smile and said, "your subordinates can't guess your mind."

"The world of mortals is charming. When will it stop? Luo Xuan's world of mortals method comes from the luck of the human race. What he gave me is also an incomplete method, but he forgot that the most suitable person to practice the world of mortals is the mortal who has fallen into the world of mortals."

"I have studied this method for tens of thousands of years and come to a final conclusion. This method only focuses on artistic conception and does not repair it. If I can survive the nine difficulties in the world of mortals, I can be the saint of all saints, and I can control the power of causality in the legend."

"Li Youyun is dignified and hard-bodied. He knows how to be grateful. He is kind-hearted. Such a pure person has stepped into the world of mortals. If he can not be confused by various desires, he can get through the first difficulty of the world of mortals." Lu Jie spoke with great eloquence.

"Do you want to take him as a disciple?" Huang pangzi was shocked and looked at Ye Xuan in great surprise.

"No."

Ye Xuan shook his head. His eyes narrowed slightly and looked at Li Youyun in the mirror of heaven and earth. A whisper came from his mouth: "if he can get through the first difficulty in the world of mortals, he will play a great role in me. Whether I can take a key step or not is all on him."

Ye Xuan said this for a little while, and then continued to speak in a low voice: "but if he can't survive the first difficulty in the world of mortals, he can only die in my hands, because I won't allow a waste to become the Minister of inviting the moon, and ye inviting the moon will be imprisoned forever because of him."

"This...?"

Huang pangzi was suddenly surprised and took a breath of air conditioning. Unexpectedly, ye Xuan gave Li Youyun such a big problem.

"Sir, your immortal Sutra goes hand in hand with the ten thousand feet of the world of mortals. It can be called the two most powerful dharmas in heaven and earth. Li Youyun is just a mortal. How can he get through the first difficulty of the world of mortals?"

"Whether he can make it or not depends on himself. I think he has already made it?" Ye Xuan's eyes were deep, as if he saw a man struggling in the world of mortals through the boundless void, but he came out of the world of mortals.

"Sir... Why did you do that?" Fat Huang doesn't understand Ye Xuan's behavior very much. Even though Li Youyun has overcome the first difficulty in the world of mortals, what's the benefit to Ye Xuan?

Unfortunately, ye Xuan didn't answer Huang pangzi's question, because it was his biggest secret and an extremely important thing about himself.

Space time seed.

Yes, it's the seed of time and space.

Ye Xuan has been practicing hard for 30000 years. He wants to integrate the magic of time and space into a seed of the power of time.

Unfortunately, thirty thousand years of hard work is of no use. These two forces are completely different and can not be integrated at all.

However, in these 30000 years, ye Xuan didn't get nothing. He finally got a way to integrate the two forces.

The power of cause and effect!

Yes, it's the power of cause and effect.

The power of cause and effect is the power beyond heaven and earth, and it is also the most mysterious power. Space and time are of the same origin and cannot be integrated because there is a missing opportunity, and this opportunity is the power of cause and effect. Only the power of cause and effect can reconcile these two forces.

For the simplest example, water and fire are incompatible, but as long as there is an appliance carrying water and the flame burns under the appliance, the water can boil.

Similarly, the force of time and space is the same. The two cannot be compatible, so we need an instrument to reconcile the two forces and completely integrate the force of time and space.

As long as Li Youyun can overcome the first difficulty in the world of mortals, a trace of causal force will grow in his body, and this is exactly what ye Xuan needs.
