Three grains of sand of time were sent, and after some small talk, Ren left alone.

His purpose is very direct and obvious, to make friends with Chu Duan.

Chu Duan knew very well that if he didn't show enough talent and potential, Ren Duxing would never do this, it was very realistic, but it was also normal, this was the world of swordsmen, you can't expect a person who has nothing to do with you to be good to you.

If Chu Duan's sword intent and mysteries were really sealed and could not be unsealed, Ren Duxing would not have taken the initiative to come to him at all, let alone send such a heavy treasure as the sand of time.

Chu Duan accepted it very calmly, Ren Duxing is not bad, he is a disciple of the True Palace, a sword king-level powerhouse, and it is also good for Chu Duan to make friends, and it will be mutually beneficial in the future.

What's more, the sand of time made Chu Duan's heart move.

After sending Ren Duxing away, Chu Duan returned to the room and closed the door, opened the white jade box again, and carefully looked at the three sands of time.

This kind of thing, if you leave it on the road outside, it is estimated that few people will notice.

It looks like ordinary sand, and the bits of golden light that flicker inside are very subtle, and it is difficult to detect if you don't look closely, and the mysterious aura that emanates fluctuates and is not powerful, so it is easy to be ignored in the outside world.

"According to Ren Duxing, the Sands of Time can only be obtained in the Divine Desolate Realm. Chu Duan said secretly.

While chatting, Ren Duxing made some introductions to the sands of time, and also explained the origin and acquisition of the sands of time, which is also a kind of investment.

At this time, the sand was obtained by accidentally encountering the tides of time and space when Ren alone entered the secret realm of the gods and wilderness in the early years, and according to the level division, the sand of time can be divided into low-level, intermediate-level, and high-level, and there seems to be a top level above.

The low-level Sand of Time is useful for the Yuan Extreme Realm swordsman, the mid-level Sand of Time is useful for the Divine Condensation Realm swordsman, and the high-level Sand of Time is useful for the Sword King-level powerhouse.

To put it simply, low-level Sand God Condensation Realm swordsmen and Sword King-level powerhouses are useless. Conversely, the intermediate Sand of Time Yuan Extreme Realm swordsman can also use it, as long as the Yuan Extreme Realm swordsman is strong enough to withstand the time force of the Sand of Time, and if he can't bear it, he will dissolve and die under the time power force.

If the Yuan Extreme Realm swordsman uses the high-grade Sand of Time, he will definitely die, and even his soul will be annihilated.

The three grains of sand of time that Ren Duxing sent were low-level sand of time, and he couldn't use them himself. It was given to Chu Duan.

Each grain of low-level sand of time can give the Yuan Extreme Realm swordsman double the time.

That is to say, after using the low-level Sand of Time, the Yuan Extreme Realm swordsman will be under the time power of the Sand of Time, and the time in the outside world is the same, but under the time of the Sand of Time time, it is faster, which is equivalent to saying that one day has passed in the outside world, and two days have passed inside.

It's amazing. Chu Duan didn't experience it personally, and he couldn't understand it for a while.

However, Ren Duxing said that if Chu Duan wanted to use the sands of time, it was best to retreat. It is better not to be disturbed, so as not to cause confusion and conflict between internal and external time.

A grain of low-grade sand of time can last for a month, which is equivalent to allowing Chu Duan to gain two months. One month more than usual.

Three grains of sand of time can give Chu Duan three more months.

The most important thing is a sentence that Ren Duxing said: the sand of time has the potential to make people understand the power of time. The so-called power of time is the artistic conception of time, the mystery of time, and so on.

This is a more powerful force than the mystery of emptiness, and the difficulty of comprehension will naturally be higher.

Three more months is actually not much at all, but for the current Chu Duan, one more day is a good thing, without hesitation, he left the room, consumed the contribution points of the outer palace, and rented a secret room, a secret room for retreat, so as not to be disturbed.

In three months, it will consume 30,000 Outer Palace contribution points, and ordinary disciples really can't afford to use it.

However, the environment of this retreat is also good, you can feel the flow of air, it is ventilated and secret, and the desolate atmosphere is several times richer than the outside world, but it is useless to Chu Duan.

Take out the white jade box, open it, take out a grain of sand of time, and condense the spiritual intention and sword intent according to the way Ren Duxing said, inject it into the sand of time, and activate the sand of time.

Suddenly, the strange mysterious fluctuations increased several times, and the golden dots in the sand of time bloomed with amazing light, filling the entire grain of the sand of time, and quickly spreading outward, and under the strange fluctuations, it shrouded Chu Duan's whole body.

The sand of time, which constantly released light, also automatically integrated into Chu Duan's body, and the golden light was restrained, seeping into Chu Duan's skin and disappearing, but Chu Duan could clearly feel its existence.

The current state is very peculiar, I feel as if I have been separated, becoming two people, in two different worlds, and the two people are completely identical.

The speed of time in the two worlds is different, one is faster and the other is slower.

It was a very peculiar state, and for a while, Chu Duan couldn't describe it clearly in words.

Time is precious, Chu Duan didn't think much about it, and hurriedly cultivated.

The first thing to do is to unseal the six stars of intent, once they are unsealed, Chu Duan will have a significant improvement in all aspects, and the efficiency of using the Nine Turns Heavenly Shock Heart Seal to actively refine the mysteries will also be greatly improved.

According to the current progress, in about two months, the god sealing blood curse on the Star of Mind will disappear, and when the time comes, the Star of Mind will be unsealed, and Chu Duan's overall strength will be much better than before.

In the retreat, it seemed that he did not know the passage of time, but when the power of that grain of time was exhausted, Chu Duan still woke up from the retreat, and above the spiritual world, there were six stars of thought, shining and brilliant, like the primeval stars, eternal and eternal.

The eyes opened, and the fierce essence broke through the air like a divine sword, and it actually pierced the air in front of him, leaving two trajectories to slowly dissipate.

Star of Ideas, unblocked!

The incomparably powerful spiritual thoughts lingered in the spiritual realm, like a volcano, ready to erupt, Chu Duan had a feeling, as if as long as he released all his spiritual thoughts, he would be able to pierce the sky.

This is an illusion, Chu Duan knew that it was because the Star of Mind had been sealed for too long, and it was unsealed all of a sudden, and the amount of power almost erupted.

It didn't take long for Chu Duan to get used to it.

This month, in fact, is two months, in addition to impacting the Divine Blood Mantra on the Star of Thought, Chu Duan also used the Nine Turns Heavenly Shock Heart Seal to refine the mysteries of water, and made progress, reaching the second turn level, and all other mysteries almost all reached the first turn, except for the mysteries of emptiness.

Speaking of which, except for the unsealing of the Star of Thought, the ascension of the mysteries did not significantly promote Chu Duan's strength, unless all kinds of mysteries could be refined to the level of at least seven turns.

Now it seems like it will take quite some time.

After resting, Chu Duan immediately took out the second grain of Time Sand to activate it and began to cultivate again.

This time, he focused on refining the mysteries, and the most important thing for him now was to refine the mysteries as much as possible, and it was best to temper them all to the limit of the eighth turn before breaking through the Divine Condensation Realm.

It is almost wholeheartedly refining the mysteries of water, the power of the mysteries of the Ouyi Danga Yin Evil Crystals, and then the star of the mind that has been unsealed all of them, the powerful spiritual intent, the Nine Turns of the Heavenly Shock Heart Seal, etc., although the speed is not as good as the mysteries of the previous quenching gold, but compared to so many mysteries, it is still considerable.

Chu Duan seemed to have disappeared in front of everyone, and no one had seen him for three months.

said that it was three months, but Chu Duan knew that he had spent six months.

In the space of six months, his progress was noticeable.

The first is the unsealing of the six stars of thought, and secondly, the progress of the mystery.

The Yin and Evil Crystals are constantly consumed, and the Aoyi Dan is also constantly consumed, and the results of Chu Duan's Mystery Quenching are obvious, and the Mysteries of Water have reached the level of three turns. All the other mysteries have basically reached the second turn, and the mysteries of emptiness are also close to the first turn.

When the time came, the three grains of the sand of time were also consumed, and Chu Duan truly realized the benefits of the sand of time, but the comprehension of the amount of time and strength was nothing.

Leaving the retreat room and returning to his room, along the way, it was inevitable that someone would stare at Chu Duan.

Back in your room, it was spotlessly clean as it was furnished to prevent dust.

After Chu Duan rested for a while, he continued to cultivate.

The refining of the mysteries is the primary task at present.

He calculated it himself, and if according to the current progress, it is estimated that it will take more than ten or even twenty years to be able to refine all kinds of mysteries to the eighth turn, then it is not counting the mysteries of emptiness.

Chu Duan thought of the Sands of Time, if there were more Sands of Time, he could save half the time, and if he could obtain the Intermediate Sands of Time, the effect would be even better.

It's just that the sands of time can only be obtained in the Divine Desolate Secret Realm, and Chu Duan has a chance to enter the Divine Desolate Secret Realm, but he originally planned to wait until his cultivation broke through to the Divine Condensation Realm before entering, but now it seems to be a bit of a conflict.

Otherwise, enter the Divine Desolation Realm now?

"With my current strength, it is not difficult to kill an ordinary Divine Condensation Realm Consummation Sword Person. Chu Duan said secretly.

Since the decision had been made, Chu Duan was about to go to the elder when someone came to inform him.

It is said that in about nine months, the Divine Desolate Secret Realm will be opened, and ask Chu Duan if he wants to take this opportunity to enter, if he doesn't enter this time, it will not be so easy to enter next time.

It seems that opening the Divine Desolation Realm is not a simple matter.

Like a pillow for sleepiness, Chu Duan immediately agreed.

It turned out that this guy also came to look for him when he was in retreat, but he couldn't find it.

"There are still nine months to go, and we can improve our strength. Chu Duan secretly said and devoted himself to cultivation.

Time flies, month by month, the time for the opening of the Divine Desolate Secret Realm is getting closer and closer, and Chu Duan's strength is also slowly improving.

Because to enter the Divine Desolate Secret Realm, there is an urgent need to improve his strength, even if it is not at all, Chu Duan did not pay so much attention to the refining of the mysteries, but allocated some time to cultivate the Heavenly Desolate Sword Technique, which was a way for him to improve his strength.

Because even if he spends all his time refining the mysteries, he can't improve his strength. (To be continued......)
