With Duan Chuchen's current strength, it was not enough to go to the central spiritual realm, and from that Tianyan's body, Duan Chuchen could feel that even the top Chi Lian was several levels lower in front of him.

Now his strength is not enough at all, maybe he can't even go to the Central Spirit Domain, what he wants now is to improve his strength first, at least let his combat power be comparable to the realm of martial arts.

And participating in the Four Great Competitions, one is that you can make contact with more masters, fight, and gain more experience through battles to break through. And during this period of time, Duan Chuchen can also follow these two masters to learn alchemy refining tools, and the profession of alchemy and refining tools is very welcome wherever he goes.

You must know that although the common currency of the four spirit feathers is Xuanjing, it is not necessarily in the central spirit domain, so your own economy is also a problem. If his alchemy and refining level go up, at least he doesn't need to worry about it financially, and it won't reach the point where it is difficult to move an inch, so he decided to endure it first, and don't rush to find the central spiritual domain.

Duan Chuchen believes that even if Na Yanwu wants to marry Xu Jingyi, Xu Jingyi will not compromise, and it is impossible for them to get married in a short period of time, that is, Duan Chuchen still has time to cultivate.

For Duan Chuchen, he has absolute confidence in Xu Jingyi, at least he won't believe that Xu Jingyi will marry him Yanwu because of a word in his childhood.

Seeing that Duan Chuchen had compromised, Duan Chuchen's three masters were also relieved, after all, if Duan Chuchen's current strength went, it would be simply looking for death, not to mention going to Xu Jingyi, whether he could reach the Central Spirit Domain was still a question. In order to reach the Central Spirit Domain, one had to pass through the "Burial Spirit Mountain Range", the "Burial Spirit Mountain Range" was full of dangers, and the "Yanyuan Swamp" was nothing compared to him.

According to the legend, the more isolated the "Burial God Mountain Range" is, the more it becomes a completely different world from the outside of the mountain range, and there are people who say that the legendary "ghost" is true, but no one has confirmed whether it is true. There are many dangers inside, even if it is a strong person who has reached the peak of the martial arts realm, it may not be able to pass through the "Burial Spirit Mountain Range" safely.

In just thousands of years, there are four strong people in the spirit realm who have entered the "Burial Spirit Mountain Range" one after another, but almost no one has come back alive. It has always been that only people from the Central Spiritual Domain can come to the Four Great Spiritual Domains, but almost no one in the Central Spiritual Domain who has successfully reached the Central Spiritual Domain has ever heard of it, which shows the horror of the "Burial Spirit Mountain".

Normally, people who go to the "Burial Spirit Mountain Range" either run away half the way and come back, or they die in the Burial Spirit Mountain Range, and there may be people who have successfully reached the Central Spirit Domain, but at least they have not heard any news. And among those who escaped from the "Burial Spirit Mountain Range", some of them cultivated no less than Elder Chilian and others.

Therefore, the "Burial Spirit Mountain" has almost become a legendary dangerous place, and in the past thousand years, no one has wanted to try to challenge it, even if it is as strong as Chi Lian, there is no such idea.

But Duan Chuchen is different, he has the confidence to challenge the "Burial Spirit Mountain Range", he must find Xu Jingyi through the "Burial Spirit Mountain Range" and bring Xu Jingyi back to his side.

Just before Duan Chuchen was about to come back, Emperor Xu's Mausoleum 'handed over' something to Duan Chuchen, which was something that Su Jingyi left for Duan Chuchen when she left, and it was also a very important thing for Duan Chuchen.

That is the map that reached the Central Spirit Domain through the "Burial Spirit Mountain Range", and with this clothing map, Duan Chuchen was able to minimize the danger of passing through the "Burial Spirit Mountain Range".

What you need to do at this time is to improve your strength, at least face the four major competitions first, and leave your own life mark on the four major competitions.

In the next period of time, Duan Chuchen was immersed in pawns and refining weapons, and there was no slightest slackness at all, seeing that Duan Chuchen's alchemy refiner was so serious, Elder Tianyun and Elder Diyu had been teaching Duan Chuchen with all their hearts, and Duan Chuchen With the help of the "Divine Alchemy Secret Technique", the speed of the alchemy refiner increased to be terrifying.

The alchemy recorded on the "Divine Alchemy Secret Technique" and the techniques of this refining weapon are much more sophisticated than those of Elder Tianyun and Elder Diyu, and I don't know how many times ahead of the techniques of the two.

Duan Chuchen had already reached the level of a high-level alchemist in accordance with the direct alchemy of the divine alchemy secret technique, and in only half a year, he had already reached the level of his alchemy and refining tools.

At this time, Duan Chuchen can already refine the heaven-level high-level pill 'medicine', even if it belongs to the upper level in the entire Heavenly Refining Sect, Duan Chuchen also has the confidence that after half a year, the level of his alchemy and refining tools will be raised to the level of the peak of the high-level alchemist, and then he will be able to refine the nine-grade spirit treasure, and the alchemy can also refine the god-level top-level pill 'medicine'.

And Chi Lian did not urge Duan Chuchen's cultivation, because at this time, the realm of Chuchen had reached a height, and it was impossible to break through in a short period of time, hoping that when the sect 'gate' was in the big competition, Duan Chuchen could make a breakthrough in the battle. However, Duan Chuchen did not cultivate, and immersed himself in alchemy and refining weapons every day, and his cultivation made some progress.

Duan Chuchen's current cultivation has made a small improvement compared to half a year ago, but it is still far from a breakthrough, Duan Chuchen found that the "Divine Alchemy Secret Technique" is very magical, and when he came to the alchemy refining tool according to the records above the secret technique, not only did he improve the level of his alchemy and refining tools, but even his cultivation would also improve, which made Duan Chuchen very surprised.

If Duan Chuchen concentrates on alchemy and refining weapons, Duan Chuchen has the confidence that even if he doesn't cultivate, he can break through to the realm of the early stage of the martial arts realm after five years.

And at this time, Elder Tianlian and Elder Diyu, Duan Chuchen's two masters had already 'handed over' all what they had learned to Duan Chuchen, and what was needed at this time was Duan Chuchen's own comprehension.

The faster Duan Chuchen comprehended, the faster they alchemized, the faster the level of refining tools improved, and Duan Chuchen's five elements also made the two elders very satisfied, in just half a year, Duan Chuchen had already been promoted to the level of senior alchemist and senior refiner, and the two elders remembered that they had learned alchemy back then, and the progress of refining tools felt embarrassed, and there was no way to compare with Duan Chuchen.

Time kept passing, and before I knew it, nearly a year had passed, and at this time, there was still the last month before the four big competitions.

On this day, in the room where the Heavenly Refining Sect was out of the dust, a strong light emanated, and the powerful light released a stream of spiritual power, which continued to circulate in the room of Duan Chuchen.

"Buzz~~~" A sword kept hovering in Duan Chuchen's "Tianxiang" furnace, and there was also a strange piece of black iron constantly circulating, with a tendency to merge with each other.

The sword was rusty, and there were gaps on the sword body, which looked very tattered, this was Duan Chuchen's tattered copper sword. And that strange piece of black iron is the "Leaving the Underworld Iron" that Duan Chuchen obtained in the Blood Cloud Society auction, and the "Leaving the Underworld Iron" has a very powerful effect on repairing the spirit treasure, and at this time, the dust is preparing to repair the broken copper sword.

Duan Chuchen's hand technique continued to flow and pinch, the fire in the furnace kept beating, and after a while, the "Leaving the Underworld Iron" had already come to the sword body of the tattered copper sword.

Between the "Leaving the Underworld Iron" began to melt, the "Leaving the Underworld Iron" continued to melt, becoming molten iron, the molten iron continued to flow towards the various places of the tattered copper sword, the molten iron turned by the "Leaving the Underworld Iron" emitted a crimson 'color' light, and the tattered copper sword was like a piece of sea at this time, constantly absorbing the "essence" of the "Leaving the Underworld Iron".

And Duan Izuchen stood aside, constantly pinching the technique, controlling the spiritual fire, and constantly smelting the tattered copper sword, Duan Izuchen felt that the sword qi slowly emanating from the tattered copper sword.

At this time, the power of the sword qi became more and more dense and powerful, and after a while, the rust in the sword body of the tattered copper sword had completely disappeared, and the simple sword pattern was revealed.

Suddenly, Duan Chuchen felt that he seemed to have hallucinations, in the endless void, a simple sword exuded endless majesty, instantly attracting tens of millions of swords, each of which exuded a very terrifying aura, and in front of that simple sword, it was like a soldier waiting for orders.

In the endless void, the sword light suddenly flowed, and the terrifying power emanated in every corner of the void, as if the heavens and the earth were shaken!

After a while, Duan Chuchen woke up from the illusion, there was obviously no rust on the tattered copper sword, and the sword body had been completely 'exposed', but it was still completely repaired, there were still some gaps on the sword body, but there were not as many as before, Duan Chuchen knew that he had not completely repaired the tattered copper sword, and at this time, two quaint characters were 'exposed' on the copper sword.

"Heavenly Sin!"

The carving of these two words is very charming, every stroke is like a shocking sword, exuding a sharp atmosphere, Duan Chuchen was shocked, it turned out that the tattered copper sword was called "Heavenly Sin", Duan Chuchen got such a long time, one of them called it a tattered copper sword, and he didn't know the name of the sword at all, and now its surface has been repaired somewhat, Duan Chuchen finally knew......
