After experiencing the semi-demon chaos, Shuofang City was a rare calm for a few days, and Su Yun's life became simpler.

He went to the Geju Academy to "class" on time every day, supervising the group of thorns from the Geju Academy, returned to Shanshuiju at noon, and cooked with Chi Xiaoyao. If he didn't want to cook, they would take three little fox monsters out for dinner.

In the afternoon, Su Yun had to go to the Geju Academy to "study" and continue to supervise the thorns. He went back to cook in the evening. After dinner, he cleaned the pot and washed dishes with Chi Xiaoyao, coaxed Qingqiu Yue, Li Xiaofan and Hu Bufang Sleeping.

Chi Xiaoyao also had to practice with him in the practice room of Shanshuiju for a while. The book monster Yingying guided her how to practice "The Change of Chilong and Liyuan". Only then would the two say good night to each other and go back to their rooms to rest.

In the dream at night, Su Yun fell into a deep sleep, his spirit was pure and his spirit grew stronger. His spiritual world was connected to Qingqiu Yue, Li Xiaofan and the uneven spiritual world of fox.

The book monster Yingying would run around these spiritual worlds and supervise the three little guys to practice with Su Yun's spiritual spirit.

However, Su Yun’s spiritual world cannot be connected with Chi Xiaoyao’s spiritual world, and the two of them are not so close that they can communicate with each other in the spiritual world.

Life is simple and fulfilling, and the girl Wutong even made some money and paid back the money she owed Su Yun.

Bai Yuelou is also trying hard to save money. After saving enough money, he plans to challenge Su Yun.

As for Li Zhuxian, he is the second richest among them. He spends three Qinghong coins to challenge Su Yun almost every day. Su Yun collected the money, but he also seriously guided her to practice.

Moreover, Li Zhuxian still has money to study at Qiu Shuijing, and even has money to bring his unsatisfied brother Li Muge.

Li Zhuxian's cultivation level was so fast that it made the others in the Geju Academy envious.

Of course, Su Yun's entry was very fast, so he could guide Li Zhuxian. The reason why his practice was so fast was because of Yingying's guidance.

Because Yingying is a book monster in Wenyuan Pavilion, she is familiar with all the books in Wenyuan Pavilion and is memorizing it. It is easy to guide Su Yun. When Su Yun fought with Li Zhuxian, she discovered Li Zhuxian's flaws. Naturally, she was able to guide her, so that Li Zhuxian could enter the country quickly.

However, although Su Yun made rapid progress, he was not the fastest among the people in the Academy of Geju.

The fastest one is the girl Wutong.

Wutong has now opened six cave heavens, and it has opened one in almost two or three days. The rapid progress of cultivation has doubled Su Yun’s pressure.

Others could not see Wutong's body, nor could they see the visions she was practicing. Only Su Yun could see that when this woman was practicing, six black caves floating above the Geju Academy!

The six caves were pitch black, twisting and rotating, as if countless demons were flying in the cave, ferocious, terrifying, evil, but deep!

Su Yun even observed Wutong's spirit.

Her spiritual body was entangled with a demon dragon, and the demon dragon was as cold as iron. When Su Yun was staring at it, the demon dragon's gloomy eyes were also staring at Su Yun.

"What a terrible woman."

Su Yun said silently in his heart: "After General Li and others left Shuofang, the human demon Wutong began to quickly absorb Shuofang's demonic nature. There was no half demon fighting with her for demonic nature, so her cultivation speed was getting faster and faster."

Book monster Yingying guessed: "This is why the night General Li and others were killed by the demon Wutong did not take action to help General Li and others resolve their demonic nature."

When this girl is fine, she always hides in his spiritual world and eavesdrops on his heart.

However, Yingying is extremely smart and can always find places that ordinary people cannot find, which is of great help to Su Yun.

"Accumulate for a few more days, you can try to open the sixth cave heaven directly."

Yingying checked Su Yun's cultivation and spiritual strength, and was very satisfied, saying: "The cave heaven is divided into Qingxu, Kongming, Taixuan, Xuanji, Jiushi and Yuqing. These six cave heavens are the six spiritual cave heavens that the predecessors have figured out from countless practices."

She found a book from somewhere and gently opened it, and saw countless words and patterns flying out of the book.

Su Yun's spirit looked up and saw that these words were about the experience of the old saint discovering the six cave heavens of the spiritual world, while the pattern was about the strange phenomenon of the old saint when he opened the six cave heavens of the spiritual world.

Su Yun checked these strange phenomena and found that among these text patterns, the ancient sage's spiritual world is divided into multiple levels. The first cave heaven is Qingxutian, located in the first level of spiritual world, while the cave heaven is rooted in the second level of spiritual world.

The second cave sky tomorrow is a deeper cave heaven, located in the second level of spiritual realm, but it is rooted in the third level of spiritual realm.

And so on.

When we arrived at the sixth cave heaven, Yuqing Cave Heaven, this cave heaven is located in the sixth spiritual world.

Su Yun looked at it carefully little by little, and the more he saw, the clearer he understood it.

The cave heaven is like a passage, a passage to the next spiritual world.

The reason why the heaven and earth are more vital and the cultivation speed in the cave heaven is actually not the function of the cave heaven, but the function of the spiritual world.

Opening the cave heaven is actually equivalent to opening the next spiritual world in advance. Although it is opened with a channel, it can greatly improve the spirit, and its cultivation strength will increase rapidly.

After reading all the text patterns, Su Yun stayed in front of the vision of the sixth cave heaven, Yuqing Cave Heaven, pondered for a moment, and said, "Yingying, the cave heaven in front is rooted in the next spiritual world, absorbing the energy of the heaven and earth from that spiritual world. So, which spiritual world is Yuqing Cave Heaven rooted in?"

Yingying showed admiration and encouraged: "Continue to ask."

Su Yun walked around Yuqing Cave Heaven, and his doubts became stronger and he said, "If the sixth cave heaven and Yuqing Cave Heaven absorbed the vital energy of heaven and earth faster and absorbed more vital energy, it means that there is another spiritual world outside the sixth level of spiritual world. Then why did the old sages not open this seventh level of spiritual world?"

Yingying flapped her wings and flew up, and said with a smile: "Most people just seek the truth, not the reason. When faced with the knowledge passed down by the old sages and wise men, they often know it, but do not think about why. Only a few people will explore the truth. Many of the scholars in the Heavenly Daoyuan are exploring the truth, and accumulating a lot of knowledge."

The moment she flew up, one book after another flew out from under her wings, one book after another bloomed, and the words and patterns gushed out from the book!

Soon, Su Yun's spiritual world was filled with countless words and patterns.

Countless voices came, and there were questions everywhere. It was because the scholars from all generations of the Heavenly Daoyuan discovered this problem after they practiced to the Soul Realm and opened the Sixth Cave Heaven. They all began to try to find out whether there was still the Seventh Cave Heaven.

Su Yun strolled in the ocean of pictures and texts, reading one book after another.

When Academicians of Tiandao were in this realm, they tried to find the Seventh Cave Heaven, but most of them failed and did not find any trace of the Seventh Cave Heaven.

These questions are the difficulties they encounter.

However, Su Yun soon discovered that some scholars made some wonderful discoveries in the process.

When they explored the seventh cave heaven in depth, they discovered various wonderful phenomena, such as a siphon phenomenon after opening the sixth cave heaven, and the spiritual energy of heaven and earth contained in the sixth spiritual world will become more invisibly.

There will also be expansion.

The sixth level of spiritual world will expand again and become wider than before.

In addition, there are some wonderful phenomena in the spirit, such as the spirit is more pure, the reflected magical powers are clearer, and the power is greater and stronger.

However, although they discovered many visions and realized that there must be a seventh spiritual world, no one could find this spiritual world, and even more so could open the seventh spiritual world.

"They call it the Seventh Spiritual Realm, and many people try to open more Sixth Cave Heavens and find out the Seventh Spiritual Realm."

Yingying flew around Su Yun and blew gently. The pictures and texts that Su Yun had browsed shrank and turned into books and fell down, saying, "This includes Xue Taichang, Qiu Taichang, Qu Taichang and others."

She left behind pictures and texts of the last few books and said, "This is the record they left."

Su Yun looked up and was shocked inexplicably.

I saw Xue Qing Mansion, Qu Jin and Qiu Shuijing, the three leaders of the Heavenly Daoyuan, chose the same path, that is, to open as much as possible the Sixth Cave Heaven!

Their cultivation path is different from others. Others can open the six major cave heavens once.

After opening the sixth cave heaven, they continued to open the sixth cave heaven until they could not continue to open it!

Among them, Qu Jin Qu Taichang opened the largest number of caves, with as many as forty-six sixth caves!

There are also many sixth cave heavens opened by Qiu Shuijing, as many as forty-three.

The sixth cave heaven opened by Xue Qing Mansion has the smallest number, but there are as many as thirty-five types!

The pictures and texts left by these three digits are filled with various strange symbols and various calculation formulas, which are extremely complex and profound and obscure.

They used these calculations to determine the orientation of different sixth cave heavens and then blasted open the sixth cave heaven.

Among them, there are even many runes, calculation formulas, and operation formulas that were created temporarily by them and were not published to the public at all!

This is even more difficult to understand.

"Fortunately, I was there when they calculated."

Shu Wei Yingying smiled and said, "The three of them have extraordinary achievements between the old saints and the new ones. They are the masters of the old saints and have also studied new academics. I converted their rune formulas and you can understand them if you read them again."

She waved her hand gently, and the various runes of Qiu Shuijing, Xue Qingfu and Qu Jin's in front of Su Yun, the formulas suddenly became clearer and no longer so obscure.

"Opening the Sixth Cave Heaven requires extremely complex calculations. Based on the old and new learning, they successively calculated the location of the Sixth Cave Heaven."

Book monster Yingying waved her hand and virtually showed these sixth cave heavens, saying, "I found that they had calculated a total of seventy-two different cave heavens. If you connect these seventy-two sixth cave heavens together, you will find..."

Su Yun looked up and saw the seventy-two cave heavens that Yingying showed. These cave heavens were not all distributed in the sixth spiritual world, but even appeared in the fifth spiritual world and the fourth spiritual world!

Su Yun even saw that there was a sixth cave in the first spiritual world!

Yingying circulated her magic power to connect these caves and heavens, but the connection was messy and there was no rule at all.

Yingying gasped and said, "You will find that the Seventh Spiritual Realm is not on the same plane at all! The Seventh Spiritual Realm is actually a fragment!"

Su Yun looked at the scene in front of him and felt inexplicably shocked.

"The Seventh Spirit Realm is actually broken into seventy-two pieces, so when they calculate, they will calculate different results."

The book monster Yingying pointed to the sixth cave in the first spiritual world and said, "So, you may open the sixth cave in directly!"
Chapter completed!
