(There was a guest at home.,Entertained and forgot to update.,I'm really sorry.,Make it up right away)

The black battleship flew like an arrow from the string over the West Lake region, shuttling between countless clouds, like a black lightning.

This black battleship, which is the battleship of the Western Tiger Sword Temple, is flying rapidly in the direction of the West Tiger Sword Temple.

Originally, there were many sword kings who went to Zhenyuan Mirror Lake, but now there are only half of the sword kings who have returned, and there are only half of them who have stayed in the Zhenyuan secret realm forever.

Every sword king who came back alive, more or less, had some gains, and each of them had improved their strength, either in terms of cultivation or swordsmanship, etc., so each of them meditated and meditated in their own rooms, making the entire battleship quiet.

In the room, Chu Duan had a sad face.

Great joy is often followed by great sorrow.

He was finally sure that the white light cluster in the dantian before should be the harvest after killing the emperor-level sword qi spirit, it can be said that it was the most valuable thing in the True Yuan Palace, far better than those top-grade True Yuan Fruits.

The dantian was expanded tenfold and stabilized tenfold, which meant that Chu Duan was able to accommodate more sword elements and withstand the impact of higher strength sword elements, and the Heavenly Desolate Sword Yuan was completely transformed into a Divine Desolate Sword Yuan, which meant that the quality of the sword element had increased tenfold.

This is permanent, but it is not comparable to a few True Yuan Fruits, even if it is more than 3,000 top-grade True Yuan Fruits and nearly 20,000 top-grade True Yuan Fruits, it cannot be compared.

Under the change of the dantian, it means that as long as Chu Duan fills up the sword yuan, whether it is in the quantity of the sword yuan or the quality of the sword yuan, it can be comparable to the ordinary creation of the Quadruple Heavenly Sword King.

In other words, in the future, compared with ordinary four-star sword kings, there is no gap in the cultivation that constitutes one of the strengths. Combined with his strong body and powerful earth-shaking power, if he bursts out with the indestructible sword intent of the top of the god level and the rule power of the top of the god level, it will be easy to sweep through the ordinary four-star sword king, even if it is an ordinary five-star sword king, he can compete with one or two.

Even if he only used the sword intent of the top of the Heaven Rank and the power of the rules of the top of the Heaven Rank to kill the ordinary four-star sword king, it was not impossible, and if the swordsmanship was fighting, the ordinary five-star sword king was not his opponent.

It's unimaginable, a two-star sword king. Its strength was strong enough to fight against an ordinary five-star sword king, it was simply a fantasy, at least, in the various territories of the primeval realm, it was unheard of, even in the primeval battlefield, it was extremely rare.

Such an increase in strength is naturally a good thing. For anyone, it is a great good thing, a great thing to celebrate for three days and three nights, and Chu Duan is also very happy. But now, after a few days of cultivation, he is distressed.

Ten times the quantity and ten times the quality, it is a hundred times. In other words, he wanted to accumulate the sword yuan of the dantian to the extent of his early stage of the Creation Dual Heaven. And it is still the quality of the Divine Desolate Sword Yuan, so it must pay a hundred times the usual energy to refine.

Two conundrums arise.

First: a hundredfold energy supply.

Second: The speed of refining, the efficiency of refining the top-grade Yuan Crystal into the Heavenly Desolate Sword Yuan Yuan and the efficiency of refining the high-grade Yuan Jing into the Divine Desolate Sword Yuan Yuan is different, and the difference is at least five times.

On the whole, Chu Duan's cultivation difficulty has increased by at least five hundred times compared to before the dantian mutation, of course, if his cultivation talent is improved, the efficiency of refining will also increase, but no matter what, a hundredfold energy supply is a hard condition.

Now the cultivation difficulty of five hundred times made Chu Duan very distressed.

The energy contained in the top-grade Yuanjing could no longer meet his needs, and Chu Duan decisively used the top-grade Yuanjing to cultivate.

This top-grade Yuanjing is often used by high-level sword kings for cultivation, and no low-level sword king dares to use top-grade Yuanjing to cultivate, because their bodies are not enough to bear it, especially the meridians.

The amount of power contained in the best Yuan Jing is much purer and more majestic than that of the top grade Yuan Jing, at least a hundred times more, under the impact, the load on the meridians is very obvious, and if it can't bear it, the meridians will be shattered, and the second is the dantian, the dantian of the low-level sword king, which cannot withstand the impact of the power of the best Yuan Jing.

Rao is Chu Duan's body is strong, and when absorbing the power of the best Yuan Jing, he didn't dare to be too fast, controlling the speed, and the meridians also felt a burst of expansion, and after pouring into the dantian, it was also filled in the dantian, fortunately, Chu Duan's dantian was ten times stronger, and it could withstand it completely.

Every time a swordsman breaks through, the dantian will expand, and it will become more stable, and Chu Duan is far beyond the swordsman of the same level in this aspect.

Rao is cultivation using the best Yuan Crystal, Chu Duan felt that the efficiency was too low, and he didn't know when Lu Dao would be able to cultivate the sword yuan in the dantian to the extreme of his current cultivation.

Mixed with joy and sorrow.

Chu Duan thought of the True Yuan Fruit, but unfortunately, the strength of the top-grade True Yuan Fruit was much stronger than that of the top-grade Yuanjing, and his meridians were not enough to bear it, unless his cultivation was promoted to the Fourfold Heaven of Creation, when his body was stronger and his meridians were more tenacious, he could bear it.

"Yuan liquid, you must find a way to buy yuan liquid. Chu Duan said secretly.

The Yuan Liquid is very pure, there are no impurities, and if you take it, the load on the meridians is much weaker than the strength of the best Yuan Jing, and it is easier to refine.

The thought of buying the Yuan Liquid disappeared, and Chu Duan took out the best Yuan Crystal again, held it in his hand, and continued to absorb it.

Although the efficiency of cultivation is very low and very low, it is better than giving up cultivation when encountering difficulties, and it will add up to a lot, and there will always be a time when it will be full, and at that time, his strength will be terrifyingly strong.

Time flies, day by day, soon, a month passes, and the black battleship also landed on the West Tiger Sword Temple, and the sword kings left the room one after another, dropped the battleship, and entered the Sword God Temple.

After a month of hard training, the aura on the overlord's body has become a lot stronger and stronger, and Chu Duan's aura has not changed much, and thousands of lower-grade true yuan fruits have been taken up, but the Divine Desolate Sword Yuan in the dantian has increased a little, compared with a month ago, it has increased by at least three percent.

It's only a three-percent increase, which is insignificant compared to the capacity of his current dantian.

In this regard, Chu Duan had no choice, who let his dantian have such a change.

This is the reward for killing the emperor-level sword qi spirit, in the past, the emperor-level sword qi spirit appeared, and the sword king who entered the Zhenyuan Hall was completely annihilated, so naturally he would not get any reward.

In fact, Chu Duan still had a question in his heart, the emperor-level sword qi spirit appeared three times before, the sword kings were all wiped out, no one came out alive, and the news was not brought out, but there is nothing strange between heaven and earth, and there is nothing strange for the powerful to find out, but what about the bones of those sword kings who died? What about their space rings?

Come to think of it, the Zhenyuan Hall is mysterious, and the bones of the Death Sword Kings and their spatial rings, etc., should all have disappeared.

I didn't know what it was, so I didn't think much about it.

Striding into the front hall of the West Tiger Sword Shrine, a glance swept over, Chu Duan pondered, how to buy Yuan Liquid.

The purchase of Yuan Liquid is not an easy thing, it is basically monopolized, and Chu Duan can't find any way.

Suddenly, Chu Duan saw someone beckoning to him, and his eyes couldn't help but light up, it turned out to be Senior Brother Qin, Qin Tianyi.

Chu Duan strode over and saluted Qin Tianyi.

"Don't be so polite. Qin Tianyi said with a smile, motioned for Chu Duan to sit down, looked at Chu Duan deeply for a few moments, then nodded and smiled: "But in more than a year, your cultivation has broken through from the First Heaven to the Second Heaven, and your strength must have increased a lot." ”

"Senior brother has good eyesight. Chu Duan said.

"Next, what are your goals?" Qin Tianyi asked casually, his tone was gentle, firstly, Chu Duan was a disciple of the Flying Heaven Pavilion and a fellow disciple, and secondly, Chu Duan's talent was recognized by him, and his attitude was naturally very good.

"Naturally, it's cultivation and ascension. Chu Duan smiled, and a flash of inspiration flashed in his mind: "Senior Brother Qin, I have something I want to ask." ”

Say. Qin Tianyi said.

"Senior Brother Qin, do you know where to buy Yuan Liquid?" Chu Duan asked bluntly.

"Yuan liquid ......" Qin Tianyi glanced at Chu Duan, but he didn't feel surprised: "The value of Yuan liquid is extremely high, and it is not so easy to buy." ”

"I just came out of the True Yuan Secret Realm and got some top-grade Yuan Crystals, but the efficiency of cultivating with Yuan Liquid is faster than that of Yuan Crystals, so I plan to buy some Yuan Liquid to cultivate. Chu Duan said simply.

"True Yuan Secret Realm...... Qin Tianyi's eyes flashed with a trace of nostalgia, he had also been to the True Yuan Secret Realm, and immediately came back to his senses: "It seems that your harvest is not small, how much yuan liquid do you plan to get?"

"The more the merrier. Chu Duan said, with his current dantian situation, he really needs a large amount of Yuan liquid, the more the better.

Qin Tianyi couldn't help but feel surprised, one catty of Yuan Liquid, at least 12,000 top-grade Yuan Crystals could be bought, and one catty and ten catties of Yuan Liquid, for Chu Duan, who was not very talented in cultivation, was far from enough, at least thirty or forty catties were needed to be able to raise the early stage of the Twin Heavens to the peak of the Twin Heavens, and if you wanted to break through to the Triple Heavens, you would need another thirty or forty catties.

After the triple heaven, the amount of elemental liquid required increased again.

One hundred catties of Yuan Liquid was equal to one hundred and twenty thousand top-grade Yuan Crystals, and Qin Tianyi felt that even if Chu Dui True Yuan Secret Realm and his party were in the Secret Realm, according to his cultivation and strength, they would not be able to gain too many benefits.

At this time, when I heard Chu Duan say, the more yuan liquid, the better, and his expression was a little weird.

"Senior Brother Chu, the Yuan Liquid of the West Tiger Great Domain is often monopolized, and it is not easy to buy it. Qin Tianyi pondered for a moment and said, "However, it's not impossible, in the Chaos Domain, there is a place to sell the Yuan Liquid, if you buy the Yuan Liquid in large quantities, you have to go to the Chaos Domain." ”

"Actually......" Without waiting for Chu Duan to answer, Qin Tianyi spoke again: "If the junior brother wants to cultivate faster, it is better to enter the Taigu Battlefield, where the environment is more suitable for cultivation. (To be continued......)
