After searching the bookshelf, the two of them looked at each other in the study, and they both saw a faint disappointment in each other's eyes.

However, how do you think about it, how do you feel that this inheritance is not in line with their efforts to pass the test of the Seven Killings and Conscience Hearts, is it just such a little gain? The two of them felt a little disappointed in their hearts.

It's just that there is no other thing in this study room except for a few paintings, desks and shelves, where else is there?

Just as Xuanyuan Hong sighed and was about to speak, Sun Hao's mind flashed with a flash of inspiration, and he made a gesture to Xuanyuan Hong: "Xiaohong, take these paintings down and take a look, be careful, don't break them."

When Xuanyuan Hong heard this, he did not doubt him, and stepped forward to take out a few paintings.

The two put the painting on the desk, Sun Hao stepped forward, beckoned Xuanyuan Hong over, and said: "If my guess is right, the test of the Demon Slaying Palace should not only be the inheritance of the way of the Fu Seal, that is too child's play, I think there may be some secrets in these paintings, Xiaohong, let's study and investigate together."

Hearing this, Xuanyuan Hong made a little head, and said with a smile: "Okay, I also think that the harvest of this study is too little."

Strictly speaking, in the study, the inheritance of the Fu Seal and the Four Treasures of the Study are all priceless, and it is also of great benefit to Sun Hao and even to the Qingyun Gate, but compared to the inheritance that may exist in the Demon Slaying Palace, this Fu Seal is probably not a particularly important thing.

In the study, there are a total of seven paintings hanging on the wall.

Seeing the number of paintings, Sun Hao was even more sure that there must be a secret in the paintings, and these seven paintings didn't correspond to the seven tests of the so-called "Seven Killings and Asking the Heart" in the Temple of Asking the Heart?

Come to think of it, the seven paintings must have some meaning.

The seven paintings do have secrets, and it is really difficult for the monks to find out if they are not taken down and carefully examined and hung on the wall.

After the seven paintings were taken down and placed on the desk, the paintings began to change a little wonderfully. The seven paintings were originally ink landscape paintings, and from a distance, they were beautiful and elegant pastoral landscapes, but after being placed on the desk, first of all, on the first painting, those pastoral landscapes seemed to come to life.

This text, Sun Hao is more familiar with than Xuanyuan Hong, looking at the words that appeared on the screen, Sun Hao read softly: "Seven killings to refine the heart....... heart to give birth to all kinds of demons, heart to destroy all kinds of demons, refine the heart, for the Taoist demon monk iron wall copper pass." If you can break this pass, you can break through this wall, and you have to break the shackles and shackles, and go straight to the avenue ......"

What is this?

Sun Hao looked at Xuanyuan Hong, Sun Hao has been practicing in the Aoki Sect for more than ten years, he has read a lot of books, and there are various cultivation methods recorded in the classics, but in general, the cultivation methods are inseparable from the three kinds of qi refining, body refining, and god refining, among them, qi refining is the most, body refining is second, and alchemy is very rare, but refining the heart, I really haven't heard of it.

Xuanyuan's red eyes flashed with excitement, and he said with a smile: "The art of heart refining is a less cultivation category among monks, according to ancient legends, among the former Buddhist sects, the most important art of heart refining, I didn't expect that in this demon killing palace, there is actually a heart refining technique, Sun Hao, this time we have made a lot of money."

Looking at Xuanyuan Hong's expression, it was obvious that this method of refining the heart was not trivial, and Sun Hao couldn't help asking: "Xiaohong, is the art of heart refining very rare?"

"Hmm", Xuanyuan Hong nodded and explained: "The monk's life is full of ups and downs, maybe there will be a so-called bottleneck at a certain stage of cultivation, and there are many reasons for the bottleneck, some are root bone restrictions, some are age restrictions, but there are also mental restrictions, that is, the mental nature is not up to par, at this time, if there is a heart refining technique, it is very likely to break through the bottleneck......

Sun Hao nodded, it turned out to be an exercise to break through the bottleneck, at this time, Sun Hao already knew that any exercise or elixir secret method, as long as it was linked to the word breaking through the bottleneck, it must be a priceless treasure.

After asking Xuanyuan Hong, Sun Hao continued to read the text in the "Seven Killings Asking the Heart", and the more he read, the more excited Sun Hao and Xuanyuan Hong became.

"Seven Killings and Asking the Heart" recorded: "The monk's life, often in danger, do not know the law, waste a lifetime, ancient legends, monks encounter the pass, the root bone is so, but the rest of the view for a long time, said, the root bone is not the absolute cause, I think, the monk practice, the qi is the mainstream, the body is the appearance, the god is high, the heart is engraved, the soul is the root, the five refining is missing, then the pass, the five refining in one, can pass the road ......."

According to the predecessor who wrote the "Seven Killings and Asking the Heart", the monk's cultivation must be refined qi, refining the body, refining the spirit, refining the heart, refining the soul and developing simultaneously, each monk realm, the strength of the monk's qi, body, spirit, heart, and soul have corresponding requirements, if the monk does not meet the basic requirements, it will encounter a bottleneck, and it is difficult to enter the next level.

This kind of saying seems to Sun Hao to be very novel, and two of the cultivation methods, "refining the heart and refining the soul, Sun Hao has heard of it for the first time".

While Sun Hao was reading, Xuanyuan Hong recorded that this "Seven Killings Asking Heart Diagram" may eventually be handed over to Qingyunmen, but the two of them can rub its content down and practice it themselves.

After reading this paragraph, the text on the first picture was finished, and Sun Hao opened the second picture while asking, "Xiaohong, is there a heart refining technique in Qingyun Gate?"

Xuanyuan Hong smiled and said: "Yes, but the level is low, I think, this "Seven Killings Asking the Heart" is definitely the top heart refining method, filling the gap in the sect, by the way, this heart refining technique is particularly important to one of my elders, how about this original picture for my elders?"

Sun Hao nodded with a smile, thinking that the elder who came to Xuanyuan Hong was probably a bottleneck, with this "Seven Killings Questioning Decision", it was likely that he would break through and make great progress, and then, Sun Hao asked again: "Is there this soul refining technique in Qingyun Gate?"

Xuanyuan Hong recalled for a moment, shook his head and said: "I didn't pay attention, the sect should not have the soul refining technique, even if there is, it is estimated that it will be submerged in the Tibetan Scripture Pavilion, and it is difficult to find it, but the sect classics seem to record that there are some special regions, and the cultivation method of soul refining is prevalent, and after cultivation, the combat power is very good, but this soul refining method is not the mainstream of the mainland."

Sun Hao nodded clearly, no wonder he didn't see any record of soul alchemy in the Qingmu Sect, it turned out that this thing was only seen in the classics in the Qingyun Sect.

Today's "Seven Killings and Asking the Heart" made Sun Hao feel the vastness of the monk world again, originally thought that the high-flying Qingyunmen would be all-encompassing, but he didn't expect that on this continent, there are still many cultivation methods that Qingyunmen can't find, think about it, the human race has existed for hundreds of millions of years, and all kinds of exercises created by generations of heroes are like the sand of the Han River, countless, how can a sect be fully recorded, it seems that when you come to Qingyunmen in the future, you can't practice behind closed doors, you have to look for opportunities everywhere.
