This sword was really a little amazing to Chen Fei, and he didn't know who created this exercise back then, and the concepts and cultivation methods involved in it were very different from many mental exercises.

That's right, the sword eye is a mental exercise, whether it is driving or cultivating, it is a change in mental power, just like the sword of slashing gods and slaughtering spirits.

It's just that the sword and soul slaying are killing the enemy, and the sword is biased, which is more of an auxiliary.

Of course, what Jian Huiyan said at the end was that it was not a long time ago that he could drag his breath out of the past, and there were limitations.

Normally, if you really cultivate the sword back eye to the peak state, the breath that has stayed in that hour can be captured at will, and there will be no pressure.

However, if like Chen Fei, there is a special trick, such as the Spirit Slaughter Technique, to cut off his own breath, then it will be a bit difficult to capture, and he must use stronger mental power to support it.

If it is more than an hour, the difficulty of capturing will continue to rise, but if the mental power is strong enough, you can continue to spend mental power to lengthen the capture timeline.

Theoretically, as long as the mental power can support it, the timeline can even be extended arbitrarily. As long as you can hold on, there's no problem.

"Discover the exercises, do you spend forty yuan stones to simplify the sword back to the eye?"

"The sword is simplifying... Simplifying Success... The sword looks back → draw a visualization map! ”

The cost of simplification is expensive, but Chen Fei did not hesitate and chose to confirm. Nowadays, there are very few exercises that can be looked down upon by Chen Fei, especially the exercises of mental power, which are even fewer.

And forty yuan stones, in the past, for Chen Fei, may be a lot of expenses. But now, under the single grade spirit sword, Chen Fei has six in his hand at the moment, and there are two more medium-grade spirit swords.

Although these spirit swords have been damaged spiritually because of the battle with Chen Fei, they can still do it if they sell thirty or forty yuan stones for each lower grade spirit sword, and even more.

The medium-grade spirit sword can go up to two or three hundred yuan stones, and these roughly add up to more than eight hundred stones. Not to mention that there is also a high-grade Zhenyuan mirror, the value of which is a little difficult to estimate.

Therefore, although Chen Fei did not find many yuan stones in the secret vault of the sword return building, the seized spirit sword had already been returned.

Therefore, the simplified cost of just looking back at the sword can no longer make Chen Fei feel distressed, after all, this kind of simplified cost expenditure is to make Chen Fei's own background stronger.

And the result of the simplification of the sword back eye is also the type that Chen Fei is most willing to see. Painting a visualization map, with the degree of differentiation of Chen Fei's mind now, it is not too easy to draw hundreds of visualization pictures at a time.

Chen Fei glanced down at the inheritance stone in his hand, thought for a moment, and with a slight exertion of his right hand, the inheritance stone instantly shattered. Not only this inheritance stone, but also the other two inheritance stones were also shocked into powder by Chen Fei one by one.

These three inheritance stones are quite large, and when they are placed in the space grid, they are quite in the way. Anyway, it has been recorded on the panel, and it makes no difference whether these inheritance stones are there or not.

After returning to the Yuanchen Sword Sect, Chen Fei wanted to dedicate the three exercises, and he only needed to take a few jade slips to record.

However, now that Chen Fei has not planned to return to the sect, and the spiritual weapons in his hand have not been sold, Chen Fei has to find a place to digest these things.

Heichengfang was a choice, although it encountered the incident of the rain building there last time, that incident did not cause Chen Fei any trouble, and even got some cultivation resources.

If it weren't for the harvest of Heichengfang, Chen Fei's current cultivation would not have reached the level of eighty-two.

However, Chen Fei didn't plan to go to Heichengfang, not because he was worried about Yulou's revenge, or the possible suppression of the owner of Heichengfang.

With Chen Fei's current cultivation, if they really have this kind of thought, then who will suppress whom in the end will have to be said well.

Even if the owner of the Black City Fang borrowed the power of the Black City Fang formation, for Chen Fei, he would have to really fight before he would know the final result.

Anyway, no matter what, it is impossible for Chen Fei to be in any danger to his life, if he wants to leave, it is impossible to stop Chen Fei in the later stage of the ordinary cultivation realm.

The reason why Chen Fei didn't plan to go to Heichengfang was just because Heichengfang couldn't give Chen Fei a satisfactory price.

Those low-grade spirit swords and middle-grade spirit swords, it's okay to say that Chen Fei had already sold them once last time, although in a short period of time, it may cause the price to drop somewhat, but the problem is not too big.

The main reason is the Zhenyuan Mirror in Chen Fei's hand at the moment, this high-grade spiritual weapon.

Heichengfang has been in the dark for so many years, and on the surface, there has never been a record of buying and selling high-grade spiritual weapons. Whether there is one in private or not, I don't know at all.

The cultivation of the owner of Heichengfang is only in the late stage of the cultivation realm, even if others have high-grade spiritual weapons, they will not buy and sell in Heichengfang, because the plate is too small.

Chen Fei planned to go to the Imperial City, the most central and prosperous place of this dynasty. There, Zhenyuan Mirror can find the right buyer and give the right price.

Both Android and Apple are available. 】

Ordinary people get high-grade spiritual weapons, and there are few cases of selling, after all, high-grade spiritual weapons are rare. But Chen Fei now needed a huge amount of cultivation resources so that he could improve his cultivation.

Zhenyuan mirror is good, it can nail people in place, whether it is killing enemies or trapping people, it is a first-class choice. But Zhen Yuanjing's improvement of Chen Fei's combat power is not so much.

Killing the enemy, the power that Chen Fei can burst out now is enough to make the general cultivation realm in the late stage of the terrifying realm.

Trapping people, the Chongyuan Sword Formation can actually trap people, Chen Fei only rarely uses it now, because in the face of the enemy, Chen Fei no longer needs to be trapped, he can go up and kill him directly.

For Chen Fei, the trapped person seems to have become a little chicken.

When a person's strength is strong enough, many moves begin to develop in the direction of simplicity. It's not that the tricks become useless, but that many of them will begin to merge with each other and become more practical.

Of course, if Chen Fei has enough Yuanshi, Zhenyuan Mirror can be kept, so he naturally has to keep it. But today's problem, isn't there enough Yuanshi!

And the Qianyuan Sword is now in a state of transformation, Chen Fei is about to have his own top-grade spirit sword, and the only way for Chen Fei to play a greater role is to sell it.

And going to the Imperial City, in addition to being the easiest place to find sellers, Chen Fei also has some curiosity about the Imperial City.

At the beginning, his strength was weak, and he wanted to cross thousands of miles to another place, but Chen Fei had more than enough heart but not enough strength. But now, in addition to those who are strong, Chen Fei's own strength is enough to protect himself.

Read 10,000 books and travel 10,000 miles.

Chen Feiwan didn't read the books, but he learned nearly 100 exercises. Now that he has achieved success, Chen Fei naturally wants to use his feet to measure this dynasty that is heading towards the sunset.

On the futon, Chen Fei swallowed the pill and concentrated on refining the medicinal power.

As his cultivation was promoted to the late stage of the cultivation realm, the seventy-two acupoints in his body were connected as a whole, and Chen Fei's refining speed of the pill became faster and faster.

Different from the previous stage when he was about to break through the late stage of the cultivation realm, at that time, every time Chen Fei opened up a trick point, he would slowly realize and perceive the changes.

At that time, it was said that he was full of confidence in the late stage of breaking through the cultivation realm, but he didn't really break through, so he still maintained a cautious attitude.

Strategically flouted, and when it came to tactics, it was still necessary to be cautious.

But now that Chen Fei is still a long way from the peak of the cultivation realm, Chen Fei has enough time to slowly realize the changes in himself.

Therefore, now taking the pill, Chen Fei almost didn't stop, refining one, and swallowing one directly.

Of the dozen or so bottles of pills that Jian Huilou obtained, most of them were to enhance Yuan Force, and it was estimated that it would take quite a long time for others to refine these pills.

One has to consider whether the body can bear it, and the refining of medicinal power, whether it is for the meridians or the acupoints, is a very big burden.

The other is whether the comprehension of the exercises and the mental power have kept up.

For Chen Fei, these are not problems, so he became a little unscrupulous when he took the pill.

The day passed in a blink of an eye, and Chen Fei stopped taking the pill halfway through, and practiced the exercises for a few hours, especially the sword back to the eye, and his mental power conjured nearly two hundred threads, and at the same time drew a visualization map.

In an instant, nearly two hundred sword eyes filled Chen Fei's sea of knowledge.

This feeling, even Chen Fei, who is completely accustomed to the perception given by the panel, is a little unbearable. There are too many insights in an instant, second only to the feeling of the last collision.

But when the spirit collided, Chen Fei's mind and consciousness were in an extremely active state, and it was very easy to absorb those feelings.

Now Chen Fei's mind is stable, and this kind of perception of two hundred percent really makes Chen Fei feel like he is being stuffed. Fortunately, Chen Fei's mental power was extraordinary, and in just a few moments, Chen Fei adapted to this state.

And once he got used to it, after this continuous feeling of having two hundred points of perception and entering the sea of knowledge, Chen Fei was actually obsessed with it.

Learning can actually make people happy, especially the sense of accomplishment after learning, which can be addictive.

The root of ordinary people lies in the fact that they can't learn a lot of advanced content, or they barely learn it, and then forget it.

And Chen Fei doesn't have this kind of concern, as long as he learns, he really learns, and this feeling of being surrounded by feelings makes people unable to extricate themselves.

For the whole night, Chen Fei was silent in the cultivation of the sword eye, and even forgot to swallow the pill.

And after a whole night of cultivation, the results were also very remarkable, and Chen Fei had already advanced it to the mastery realm at this moment.

Even in the mastery realm, he had already run a long distance, and according to Chen Fei's estimate, in less than ten days, Chen Fei would be able to return his sword to the realm of Great Perfection.

You must know that before, in the entire Sword Return Building, only Xing Xinzhao was the only one who cultivated the Sword Back Eye to the peak, and most of the others were just wandering back in the entry position.
