Refusing Chi Xiao's challenge, Chi Xiao actually used a rogue method to follow Chu Dui to the death, Chu Duan wanted to relax, and he was naturally unhappy with a tail, so he had to agree to fight with Chi Xiao.

"Here it is. Chu Duan said.

"Look at the sword. Chi Xiao shouted, the sword came out of the sheath, split the mountains, and a sword slashed and slashed, and the sword light like a demon king came.

The people around him only felt suffocated, as if they were choked by the throat, unable to breathe, trembling all over, as if they were shocked by the demon king, this sword of Chi Xiao was much stronger than the hundred years of the outer palace.

It's just that Chu Duan is even stronger.

The flaws in it can be seen at a glance, Chu Duan's sword is unsheathed, the power of ice spirit spreads into the sword body, and the spiritual intention and the sword intent at the beginning of the seven turns are all injected, and the extreme mountain shaking power is launched, and the power is even more powerful.

didn't use the mystery of gold, followed the flaw to counterattack, broke Chi Xiao's attack, and pointed at Chi Xiao's wrist vein, the power of ice spread, and the power of concussion swept and impacted, making Chi Xiao's arm instantly frozen and numb, unable to move.

Just a breath of time is enough to tell the winner from the loser.

Putting the sword into the sheath, Chu Duan turned to leave, and Chi Xiao looked at Chu Duan's back in a daze, with a heartfelt shock on his face that could not be concealed.

Unexpectedly, he has improved, but Chu Duan's progress is greater than him, and the gap between the two sides is more obvious.

......

After some distraction, Chu Duan returned to the room and began the next step of cultivation.

Cultivation has been restored to the limit of the Yuan Extreme Realm, and the purity of the Heavenly Desolate Sword Yuan is a higher level than when he was in the Tianfeng Sword Palace, it can be said that whether it is in terms of quantity or quality, Chu Duan's Heavenly Desolate Sword Yuan has reached the true extreme.

As long as Chu Duan is willing, it will take a day or two to break through the Heaven Conquering Dafa, and he will be able to make a breakthrough in cultivation immediately. Reach the Divine Gaze.

He could feel that his sword yuan had a feeling of instability, gradually making waves, ready to move, restless, that was a sign of reaching the extreme, breaking through to a higher level, but because Chu Duan's cultivation talent had not improved, he was restricted and could not break through.

So far. The Heavenly Desolate Sword Yuan doesn't have to cultivate anymore, the quantity and quality have reached the extreme, and it will not regress, Chu Duan will use this time to take the Ice Extreme Pill to cultivate the Ice Spirit Frost Skill, in addition, the third layer of the Heavenly Desolate Sword Body is also cultivating, the swordsmanship and the amount of concussive power are also being studied, and the unsealing of the Star of Mind is also in progress, the most important thing is. Because the mysteries of gold had reached the limit of the eighth turn, and also reached the limit of what Chu Duan could refine, he began to unseal the second mysteries.

The unsealing of the second kind of mystery is also learned.

Among all the mysteries that are sealed. The mystery of emptiness is the most, and the difficulty of comprehension is also the highest, and even Dacheng has not reached it at present.

There is no doubt about the difficulty of refining the mystery of emptiness after it has reached perfection. It will be many times more powerful than the others, and in the same way, the power of the void will be many times greater than the others.

For the time being, I will not unravel the mystery of emptiness. Other mystical choices, Chu Duan will be the first to choose the mysteries of water, the mysteries of gold, and the mysteries of water.

Of course, it is also a good choice to re-comprehend the artistic conception of the wind and enhance it to the mystery of the wind.

In fact, in Chu Duan's heart, there was another thought, an idea that even he was shocked, that is, to unseal all the mysteries, comprehend them all to perfection, and then refine them together, and all of them were raised to the limit of the eighth turn.

I have to say that Chu Duan's ambition is very great, this kind of idea is very crazy, once it succeeds, it can be said that there is no one before or after, no one can reach it.

There are nine meanings of wood, water, fire, earth, wind, ice, thunder, clouds, and emptiness.

If you count the mysteries of gold, there are ten, and there are very few swordsmen who comprehend five mysteries, and there are very few swordsmen who comprehend ten mysteries and plan to refine each of them to the extreme.

If it is known, I don't know what kind of storm it will set off.

But this is a hole card, it is his secret and dependence, Chu Duan will not announce it, even if the battle is known in the future, it is because of the battle.

Such a crazy thought appeared in his mind, Chu Duan couldn't contain it, and that madness, like a seed sprouting, could not be stopped and suppressed.

He knew that refining a single mystery one by one was the right approach, and it was in line with the mainstream of the swordsmen of the primeval realm, otherwise there would be a lot of mysteries, and the efficiency of refining would be greatly reduced.

Once he unsealed all the mysteries, there would be no second chance to seal them again.

It's just that he couldn't suppress his inner thoughts, that kind of madness, unprecedented, made his blood boil, and his soul almost burned like a passion.

A choice, a very difficult and extremely important choice.

This is a gamble, if he wins, his achievements will be beyond his imagination, and if he loses, he will be a little unsatisfactory.

In the room, Chu Duan's breathing became rapid, because the blood was boiling, and his face was congested and red.

"If you fight, if you fail, it's a big deal to break through to the Divine Condensation Realm. Chu Duan's breathing became steady, and he said to himself, his eyes becoming more determined than ever.

The so-called failure is that it is impossible to complete the tempering within a certain period of time and achieve the expected goal, as for how long the time is, in fact, Chu Duan himself has no bottom, everything depends on feelings.

Success, it is even simpler, in the ideal time, to refine all the mysteries to the extreme.

High stake!

Chu Duan made a choice, taking a gamble and betting on an unimaginable future.

Since you have made a choice, you must treat it carefully, you must not be careless, and you must not leave irreparable regrets because of any negligence.

Exhaled, Chu Duan's mind already had a clear idea.

The mystery of gold has reached the ultimate of the eight turns, but you don't need to pay attention to it, the other, the established nine mysteries, the mystery of the wind have disappeared because of the previous decomposition, and they need to be re-comprehended.

With Chu Duan's current soul strength and comprehension, and because the sword intent and mysteries had reached the limit of the eighth turn, deliberately, in just three breaths, he felt the fluctuations of the wind around him, and the artistic conception of the wind immediately reached one percent.

However, in just sixty breaths, the artistic conception of the wind has reached ten percent perfection, and it is easy to break through and be promoted to the mystery of the wind.

The speed of comprehension of the mystery of the wind was ten times slower than that of the artistic conception of the wind, but for Chu Duan, there was still no difficulty, and with his comprehension, the light car was ripe, and the speed was shocking.

A day later, Chu Duan successfully comprehended the mystery of the wind to perfection, and the cyan breath surrounded his body, supporting his body to float in the air, which was very beautiful.

The first mystery reaches its consummation.

Next, Chu Duan unsealed the second mystery: the mystery of wood.

The speed of comprehension of the mysteries of the wood is about twice as slow as that of the mysteries of the wind, after all, the mysteries of the wind have already reached an extremely advanced level of comprehension before, and they are very familiar.

Although the speed is a little slower, it is still many times faster than the speed of other people's enlightenment.

This time, it took Chu Duan three days to comprehend the mystery of the wood to perfection.

Unseal the third mystery: the mystery of water.

The difficulty of comprehending the mystery of water is better than that of wood.

Chu Duan simply found a place with a river, sat by the river, felt the breath of water, and helped to comprehend, and it took six days to comprehend the mystery of water to perfection.

Unseal the fourth mystery: the mystery of fire.

This time, he was in the room, communicating with the desolate fire of the earth's heart, helping to comprehend, and it took a full twelve days to comprehend the mystery of fire to perfection.

The fifth mystery: the mystery of the earth.

Sitting on the ground, feeling the fluctuations of the earth, twenty-four days later, the mystery of the earth is complete.

Up to now, the five mysteries of wind, wood, water, fire and earth have been consummated, and Chu Duan has spent a total of forty-six days, according to this law, it is estimated that the sixth mysteries will take forty-eight days, the seventh mysteries are doubled, the eighth mysteries are still doubled, and the time spent on the mysteries of emptiness is only afraid that it will be longer.

Next, it will take a lot of time to refine.

"It seems that Tianwu Dan still has to be used after all. Chu Duan said secretly.

It is true that Tianwu Dan is very precious, but no matter how precious it is, if it is not used, it is just an ornament.

Maybe keeping the Tianwu Pill will be of greater use in the future, however, if you don't use it now, you will waste more time in vain, it is better to use it now, save time, and win the future, no one knows the way, in the future, can you get more Tianwu Pill or get a more advanced pill than Tianwu Dan.

The open-minded mentality made Chu Duan see it at once.

Since he decided to take the Heavenly Enlightenment Pill, Chu Duan immediately unsealed the mystery of the void and the real first, and then decomposed it, returning to the source and returning to the mystery of the clouds, and then unsealed the mystery of ice, the mystery of thunder and the mystery of emptiness.

Of the four mysteries, the mysteries of clouds are only one line away from reaching perfection, the mysteries of ice and thunder are both reaching the great perfection, and the mysteries of emptiness are only a small success.

Get ready, Chu Duan took out the Tianwu Pill and took it, the medicinal power spread, and the whole person immediately entered a state of epiphany, but Chu Duan could clearly feel his own state, and he could also feel that his understanding seemed to have increased more than ten times.

The increase in comprehension of the precious pill of Tianwu Pill is proportional, and the higher the comprehension, the better the effect.

The tenfold increase in comprehension does not mean that Chu Duan's comprehension speed has increased tenfold, but dozens or even a hundred times.

Time is only one hour, in fact, it is very short, Chu Duan did not dare to waste the slightest, and immediately comprehended the mystery of the clouds, just an instant, the mystery of the clouds was complete.

Next, it is the mystery of ice, not long after, the mystery of ice is also complete, and then the mystery of thunder is also comprehended to perfection, half an hour has passed, there is still half an hour left, Chu Duan immediately participated in the mystery of Wukong. (To be continued......)
