Sure enough, it didn't take long for the elders of the three major families of Chaos City to visit the Heavenly Desolate Divine Mountain, take out the portraits, and look for Chu Duan.

Chu Duan is a celebrity, and the disciples of the outer palace all know him, so he can find it effortlessly.

The three major families offered millions of top-grade barren stones and a lot of elixirs, elixirs and ores as gifts to make amends, and wanted to resolve grievances with Chu Duan, and Chu Duan accepted them unceremoniously.

After accepting the gift, Chu Duan turned around and left, and under the inquiry of the elders of the three major families, he realized that Chu Duan was the first place in this year's Outer Palace Centennial Competition, and the first disciple of the Outer Palace.

Fortunately, he gave a gift to resolve this grudge.

After breathing a sigh of relief, the elders of the three major families also left the Heavenly Desolate Divine Mountain one after another and returned to their respective families.

In fact, after Chu Duan returned to the Heavenly Desolate Earth Palace, he did not deliberately find the three major families of Chaotic Sky City to settle accounts, unless he went to the Chaotic Sky Domain again, he would look for trouble by the way.

It is not true to say that there are grievances, Chu Duan himself has no loss, but the three major families, together with nearly twenty Divine Condensation Realm swordsmen, have suffered huge losses, and he has to apologize for the last time, no matter how he says it, Chu Duan has earned it.

This matter ended like this, and Chu Duan didn't remember it, a trivial matter, it was not worth bothering.

Returning to his room, Chu Duan began to cultivate, and outside, there was a discussion again, about the elders of the three major families of Chaos Sky City going up the mountain to apologize, all kinds of speculations, no matter what, Chu Duan, who had been silent for a long time, became the center of the topic again, fortunately, this is not a particularly sensational thing, and the discussion will soon dissipate.

The six stars of thought were sealed by the Divine Blood Curse as one, and Chu Duan could only crack it together. Therefore, it is more difficult and takes more time.

In the Spiritual World, the prototype of the sword spirit looks more condensed, and the eight-turn extreme sword intent is restrained, and the edge is deeply hidden, while the mystery of gold is entrenched in a corner of the Spiritual World, releasing a brilliant and amazing light.

The other mysteries occupy a corner of each other, and all of them are wrapped in the gray force, which is the power of the yin evil crystal.

Each of them reaches the meaning of perfection. All of them are eroded by the power of the Yin Evil Crystals, tempered in the confrontation, and constantly purified.

It's just that there are too many mysteries, which delays the speed of refining, and the progress is very slow.

Chu Duan took out the Aoyi Pill and took it, and then combined it with the Nine Turns Heavenly Earthquake Heart Seal to refine the mysteries of water, and suddenly, the efficiency increased several times.

The use of yin and evil crystals is one way. Allocating some time each day to come out, and taking the initiative is the second way, a two-pronged approach.

Chu Duan planned to take the initiative to refine a mystery to the extreme, that is, the limit of the eighth turn. Then refine another kind of mystery.

How much time does it take to be able to refine all the mysteries to the limit of the eighth turn, Chu Duan has no bottom in his heart, and he feels very slow. It's too inefficient.

But it's man-made, and it may be possible to spend more time and effort.

The Heavenly Desolate Sword Yuan doesn't have to cultivate for the time being. The cultivation of the third layer of the Heavenly Desolate Sword Body is still necessary, in addition, it is necessary to cultivate swordsmanship, and it is necessary to impact the Divine Blood Spell on the Star of Thought, as well as other aspects of cultivation, etc., all of which will take time.

Time, time is what Chu Duan is most lacking right now.

If time could buy it, he would be willing to pay a huge price.

It's a pity that time can't buy it.

The Star of Mind has not yet been unsealed, and the efficiency of active refining is still a little unsatisfactory, after the refining is completed, Chu Duan took out the "Heart Sword Secret Record" and flipped through it carefully.

After returning to the Heavenly Desolate Palace, he also looked through some classics and found some records about the Sword King of Zhuxin.

The Sword King of Zhuxin is a sword scatterer, but his fame is very great, according to records, his strength is very strong, before disappearing, he reached the level of the seven-star sword king, and belongs to the high-level sword king.

In the records, the seven-star sword king-level Zhuxin Sword King has killed the eight-star sword king, which seems to be directly related to the exercises he has cultivated.

You must know that the gap in strength between the Sword Kings is even greater, and the gap between each star may even be ten times.

It is already difficult for the Seven-Star Sword King to compete with the Eight-Star Sword King, and it is even more difficult to kill.

In this way, Chu Duan is more interested in "The Secret Record of the Heart Sword", perhaps, the reason why the Sword King of the Heart is so powerful is here.

After reading it carefully, this "Heart Sword Secret Record" is really unfathomable, and it is a very special and powerful exercise.

It took half an hour to read it slowly almost word by word, savoring it carefully, and studying it for half an hour, before Chu Duan finished reading this "Heart Sword Secret Record", which was not thick and only a dozen pages.

The material of this book is very special, like the skin of some kind of beast, it feels very good and comfortable to the touch, and the book made of this kind of leather is extremely difficult to damage, and can be preserved for 10,000 years without rotting.

After flipping through the pages, closing the book, Chu Duan closed his eyes, and the contents of the book flowed back through his mind, every word, every sentence, every paragraph, and every page, like flowing water flowing through the center of his brain.

As we all know, swordsmen practice, major in sword qi and then transformed into sword yuan, but "Heart Sword Secret Record" is not, it is a very special exercise, it cannot be regarded as an auxiliary exercise, but it cannot be regarded as a major exercise, any swordsman, while practicing the main practice and auxiliary exercises, can also practice the "Heart Sword Secret Record".

It is mentioned in the "Heart Sword Secret Record" that there are two prerequisites for cultivating this special technique, a strong soul and a sword heart.

The so-called sword heart is to use the heart of the sword, focus on the sword, be sincere to the sword, and refine the sword.

The two prerequisites have restricted many people, and even if they get the "Heart Sword Secret Record", they will not be able to succeed in cultivation.

Sure enough, powerful exercises are not so easy to cultivate.

For Chu Duan, a strong soul and sword heart are not a problem, he can cultivate the "Heart Sword Secret Record".

It's just that there is another restriction to the cultivation of "Heart Sword Secret Record", that is, it must have the power of divine thoughts.

In other words, Chu Duan can't cultivate the Heart Sword Secret Record now, and he must wait until his cultivation breaks through to the Divine Condensation Realm and his spiritual thoughts are transformed into the power of divine thoughts before he can start cultivating the Heart Sword Secret Record. This made Chu Duan breathe a sigh of relief, because even if he could cultivate now, it would be difficult for him to squeeze out time, so he had to give up for the time being.

Since he couldn't cultivate the Heart Sword Secret Record now, Chu Duan put it into the space ring.

It can be said that there are a lot of heavy treasures in Chu Duan's space ring, "The Secret Record of the Heart Sword" is one, the inheritance of the Heavenly Dragon Sword Saint is one, and there are many treasures of great value in it.

With the cultivation, the mysteries of water have finally reached a turn, but the other mysteries, it will take a considerable amount of time to turn away, and the refining speed of the mysteries of emptiness is the slowest, almost immovable, Chu Duan doesn't know how long it will take to quench the mysteries of emptiness to a turn.

Today, when Chu Duan finished his cultivation and was about to take a walk outside, he ushered in an uninvited guest, who was also a distinguished guest.

Go alone!

"Senior Brother Ren. Chu Duan was surprised, and saluted Ren Duxing, respecting him from the heart.

First, Ren Duxing is a disciple of the True Palace, a strong man at the Sword King level, and secondly, Ren Duxing brought him into the Heavenly Desolate Palace, although it is said that the three-level assessment is not difficult for Chu Duan.

Ren Duxing stared at Chu Duan for a while and nodded.

"Why don't you invite me in and sit down? Ren Duxing smiled slightly and said.

"Senior Brother Ren, please. Chu Dui led him and let Ren Duxing enter the room.

Ren Duxing walked in and looked around, and sighed in a tone that seemed to be nostalgic: "Many years ago, I also lived in such a room. ”

Chu Duan is a person who doesn't talk much, and he often doesn't take the initiative to find any topics, so he didn't take over the words of the lone line.

"Isn't it surprised that I came to you. Ren Duxing turned to look at Chu Duan and said with a smile.

"Hmm. Chu Duan nodded, speaking of which, he was actually not familiar with Ren Duxing.

"I'm here to congratulate you on winning the first place in the Outer Palace Centennial Competition. Ren Duyi did it on the chair on the side, and said to Chu Dui: "Although it has been slow for a while. ”

As he spoke, a white jade box appeared in Ren Duxing's hand, the jade box was crystal clear, and at a glance, he knew that Lu Dao was not an ordinary jade box, such a precious jade box, and the things placed inside should not be ordinary.

"This is a congratulatory gift from me, and you can also think of it as an investment. Ren Duxing spoke very directly, and the white jade box flew towards Chu Duan.

This is a gesture of goodwill, as Ren Duxing said, an investment, he took a fancy to Chu Duan's potential and wanted to make friends.

Chu Duan glanced at Ren Duxing and caught the white jade box.

"You open it and take a look. "Let me walk alone.

Chu Duan glanced at Ren Duxing again, opened the white jade box, and saw that inside, there were three grains of sand and stones placed side by side.

The size of the three grains of sand and gravel is almost the same, almost like a soybean, yellow-brown, with golden dots, like the light of the stars, making the three grains of sand and gravel that look very ordinary suddenly full of mystery.

Chu Duan's gaze fell on the three grains of sand, and for a while, he couldn't move away, because he felt that on the three grains of sand, there was a mysterious aura fluctuation, which was very profound and unfamiliar.

"That kind of sand is called the sand of time. Ren Duxing's voice sounded.

"The Sands of Time ......" Chu Duan repeated, the first time he heard this name, he didn't know what Lu Dao was, and he felt a throbbing in his heart.

"The sand of time, also known as the sand that contains the power of time. Ren Duxing said, making Chu Du's heart jump wildly.

Sand with the power of time!

The amount of time force is a force that is more mysterious and powerful than the force of space.

Chu Duan's expression changed, his pupils expanded and contracted and trembled, and he was completely seen by Ren Duxing, he smiled slightly, and then continued: "These three grains of sand of time are low-level sand of time, suitable for use by swordsmen of the Yuan Extreme Realm. ”

When Chu Duan heard this, his heart moved again, his eyes moved away from the three grains of sand, and fell on Ren Duxing's face, waiting for Ren Duxing to continue, he felt that this might be an opportunity for himself. (To be continued......)
