As for how Yang Kai persuaded Huigu to cooperate with him, it was his own ability and personal charm, and Xu Linggong was too lazy to pay attention to so much.

"My cultivation of Kaitian Realm is all accumulated over the years, refining Kaitian Alchemy and cultivating various levels of cultivation resources. This is also the most orthodox way of cultivation for Kaitian Realm warriors since ancient times. Although it takes a long time, it is better than safe."

"There are people who want to take shortcuts. Refining the foundation of the Qiankun world for their own use is a method, but this method has great disadvantages. That is, the foundation of the refined Qiankun world may not be able to perfectly match oneself. Once there is any repulsion, it will even make the foundation of oneself pass away, which is not worth the loss. Every Qiankun world is unique, including the small Qiankun in our Kaitian Realm warriors. How difficult is it to find a perfect fit for oneself?"

Xu Linggong's voice slowly came into Yang Kai's ears.

Yang Kai nodded slightly. He had seen that Kaitian Realm wanted to refine the Demon Realm and heal his wounds, but was blocked by him. In the end, the refiner was also killed. The great power of the world that evacuated after his death nourished the Demon Realm.

"However, shortcuts are difficult to take, but it does not mean there is no shortcut!"

Yang Kai's expression moved: "Senior means..."

Mr. Xu Ling looked at him meaningfully: "You had a lofty ambitions and wanted to directly advance to the seventh grade to open the sky, but this touched the bottom line of many people. In the end, I was forced to achieve the fifth grade in that broken sky. After all, how many years have passed? How could a fifth grade be promoted to the sixth grade in this short time? I believe that the information you have obtained is correct. What you achieved in the broken sky should be only the fifth grade, not the sixth grade."

Yang Kai remained silent. He couldn't hide such a thing even if he wanted to hide it. After all, when he was promoted, so many people saw it, and Qu Huashang was also present. It was not surprising that Xu Linggong knew this.

"It is rumored that there is a magical medicine in this world called the World Fruit. The world fruit is divided into three grades, middle and lower, corresponding to the Kaitian Realm. That world fruit can allow warriors to directly advance to the first grade without any hidden dangers!" Xu Linggong said to himself, "You and Qu Yatou had been to Taixu Realm. Someone once auctioned a low-grade world fruit in my Yin and Yang Realm, and that person also went to Taixu Realm. According to the information found out by my Yin and Yang Realm, the person's low-grade world fruit was obtained from the Taixu Realm!"

"So, you can be promoted from fifth grade to sixth grade in such a short time, probably because you took a medium-grade world fruit!"

"Senior's eyes are like a torch!" Yang Kai admitted frankly, "I am indeed taking the World Fruit of this sixth grade Kaitian now."

"Okay!" Xu Linggong smiled slightly, "If this is true, then you and Yatou Qu are considered to be of equal status! I was a little worried that your future limit would be a little different from Yatou Qu in the future, but now it seems that I am too worried."

Yang Kai was promoted to the fifth grade, and his limit was the seventh grade, but with a world fruit, he was promoted to the eighth grade, the same as Qu Huashang. As long as time permits, he can be promoted to the eighth grade sooner or later.

"You have a good opportunity to get such a treasure as a medium-grade world fruit. No wonder you were willing to be promoted to the fifth grade in that broken sky." Xu Linggong nodded slightly and looked at Yang Kai with some praise, "Take the world fruit is the biggest shortcut you know so far!"

"Senior means... are there any other shortcuts?"

Xu Linggong smiled slightly: "Nature, these three thousand worlds are vast and mysterious. Even if we are the best-quality open sky, we may not be able to explore thoroughly after spending our entire life. You have never heard of it because you don't have enough experience and vision."

Yang Kai said solemnly: "Please give me some advice!"

Xu Ling said righteously: "Have you ever heard of the River of Time?"

"The River of Time?" Yang Kai was stunned.

"That is the product of the creation of heaven and earth, and it is the place where time is nurtured. In that river of time, the flow rate of time is different from that of the outside world, which may be ten times, hundreds times, or even thousands times. Do you know what this means?"

Yang Kai was shocked: "Can you practice in the river of time be equivalent to ten years outside, a hundred years or even a thousand years?"

"That's true!" Xu Linggong showed a look of aftertaste, "On the outside world, you have practiced for ten, hundred and thousands of years. The foundation you have accumulated is naturally much deeper than others. Moreover, this is a normal accumulation of precipitation, so there is no hidden danger. Back then... I entered a river of time and gained a lot!"

Yang Kai looked shocked. There was a strange thing like the River of Time in this world. If it weren't for the words from Mr. Xu Ling, he would have been a little unbelievable.

But soon, he remembered the Emperor of Time!

Emperor Time is proficient in the laws of time, and the God of Time left behind was once enfeoffed with the power of time. Yang Xiao and Yang Xue, two little guys, had been in seclusion for hundreds of years, but they were only a few years outside. In this way, the God of Time is a river of time created by Emperor Time.

It’s a pity that the power of the sealed years has been exhausted, and the flow rate of time in the God of Time has returned to normal.

From this point of view, Emperor Time is worthy of being a genius of eternity. If he had not suffered unexpected death in Mo Sheng, he would have had his place in these three thousand worlds.

Thinking of this, Yang Kai looked slightly moved: "Senior, is the opportunity you mentioned to be the river of time?"

Mr. Xu Ling laughed: "You think it's so beautiful. If someone encounters this thing, the River of Time, would have entered it and practiced long ago. If you don't consume the power of time, you can't leave it at all, so you don't have to think about the River of Time."

Yang Kai was stunned and realized that the River of Time was actually something similar to a consumable. If it was really discovered, it would not be preserved forever.

"You don't have to think about the River of Time for the time being. This thing is very rare in the Three Thousand Worlds. Even if it really appears, it's not your turn." Xu Linggong paused for a moment and then said, "The River of Time is a shortcut, and the other is the Xiaoyuan Realm!"

"Xiaoyuan Realm?" Yang Kai frowned slightly, his face showing a look of confusion. He had never heard of Xiaoyuan Realm before.

"You have obtained the world fruit, and you must have entered the world of that fruit."

Yang Kai nodded: "Not bad."

Moreover, after entering more than once, Yang Kai couldn't help but recall the experience of using the Xiaoxuan Realm to cheat in Taixu Realm and leading a group of people to explore the world of more than a dozen fruits.

In the end, he got furious about the fruit tree of the world fruit and beat him up. The past is so unbearable to look back on.

"The small source world is somewhat similar to the fruit world you have entered. It can be said that the small source world is a weakened version of the world fruit."

"Sir, please give me advice!" Yang Kai said humbly.

"In that small source realm, the flow rate of time is also different from that of the outside world. If you can refine a trace of the original power of the small source realm, you can obtain part of the world power of the small source realm, integrate it into yourself, enhance the foundation of your own small universe, and save years of hard practice!"

Yang Kai's eyes lit up when he heard this.

By refining the original power of the Xiaoyuan Realm, you can gain the great power of the Xiaoyuan Realm. In this way, as Xu Linggong said, it can enhance his own foundation and save time in hard practice.

No wonder he said that this Xiaoyuan Realm is a weakened version of the World Fruit. The World Fruit can help Kaitian Realm to directly advance to the first level, but Xiaoyuan Realm cannot.

"But compared to the world fruit, the Xiaoyuan Realm also has its own advantages. The world fruit can only be taken by one person, but the Xiaoyuan Realm can become a place for many people to experience. The Xiaoyuan Realm is one of the foundations of our Cave Heaven and Blessings. Every Cave Heaven and Blessings has more or less Xiaoyuan Realm. There are three small source realms in my Yin-Yang Heaven!"

Yang Kai's expression moved slightly: "The opportunity mentioned by senior..."

Xu Ling said righteously: "Yes, I want to give you the opportunity to enter one of the small source realms. This small source realm is also the highest among my Yin and Yang Heaven. If you can refine a trace of the original power in it, you will definitely gain great results!"

Yang Kai said movedly: "Thank you, senior!"

Such a great gift is not an ordinary hand. Qingkui said before that even in the Yin and Yang Heaven, such opportunities can only be obtained by a very small number of people.

Yang Kai could also guess one or two things. Although the Xiaoyuan Realm, as Xu Linggong said, can become a place for many people to experience, every time someone refines a trace of the original power of the world, the existence of the Xiaoyuan Realm will become a little weaker, and one day, the Xiaoyuan Realm will completely disappear.

Compared to a one-time consumption thing like the World Fruit, the Small Source Realm can only use it more times, but the effect is not as good as the World Fruit. Both have their own advantages and disadvantages.

However, there is always a limit, so all those who can enter these small source realms are the most outstanding warriors in Yin and Yang Heaven.

However, for a sect, the existence of the small source world is undoubtedly more important than the world fruit. The former can help many disciples improve their strength in a very short time, while the latter can only be used by one person.

It must have taken a lot of trouble to make Xu Linggong open the small source world to such half an outsider.

"You don't have to think too much. I am also for Qu Yatou. You have been promoted to the sixth grade for the sake of Qu Yatou. Your foundation is unstable and your foundation is insufficient. You can just settle down and accumulate it when you enter the Xiaoyuan Realm. Otherwise, you will die early when you encounter danger. Wouldn't you be wronged Qu Yatou?" Xu Linggong said lightly, "And even if you enter the Xiaoyuan Realm, you may not be able to gain anything. It all depends on your own efforts and opportunities."

"Don't worry, senior, I will do my best!" Yang Kai said seriously.

"Here!" Xu Linggong suddenly stopped and stopped in a void.

Yang Kai looked up, but could not see anything.

However, Xu Linggong flew with his hands and changed constantly. He suddenly pointed forward and whispered: "Please give me the best!"

A stream of light came out, and layers of ripples appeared in the void ahead.

After the ripples, an old man sitting cross-legged in Yang Kai appeared strangely in Yang Kai's vision. The old man's hair and beard were all white, his long eyebrows fell in front of him, his upper body was naked, his muscles were rising, and his bronze light seemed to be hidden in it. He only wore a pair of linen trousers and his feet were naked.
