The dwelling environment prepared by the East China Sea for the great monks is very good, not only is the spiritual energy abundant, but also all the equipment is available, which is almost not inferior to the ordinary high-grade cave mansions, which shows that this master of the East China Sea Country has also put a lot of effort into receiving these fellow Daoists of the Yuan Realm in order to hold this conference.

After all, they are all in the Supreme Yuan Realm, a powerful existence standing at the peak of this realm, if there is no major conflict of interest, they must try to have a good relationship with each other, if they anger each other because of some trivial things in the reception, or make the other party secretly unhappy in their hearts, it will be too unreasonable.

Therefore, Donghai obviously ordered his subordinates to make all preparations in advance, and make sure that everything is as perfect as possible.

There are fifteen of the top cave mansions, because when he entered the inner city of the East China Sea, Li Xian also obtained the qualification to enjoy one of the top cave mansions, and looking at the scale of the cave mansions, it seems that it is still quite good among the fifteen top cave mansions, ranking the top few.

Second only to the Imperial Palace of the East China Sea Province, where Tokai himself lives.

It seems that Donghai attaches great importance to him, after all, Li Xian just seemed to be a monk at the peak of the late stage of the merger at the beginning, and he could exert the power of the Supreme Yuan Realm, easily defeat several Great Cultivators of the Escape Realm, and at the same time, when he exchanged, he also took out a large amount of the essence blood of the Heavy Extreme Beast, which showed that he at least had the ability to defeat the Heavy Extreme Beast, which the Supreme Yuan Realm monk Yujian also had a headache.

Not only was he able to defeat it, but he had also obtained so much Heavy Extreme Beast Essence Blood, it was obvious that his combat power was outstanding even among the Great Cultivators of the Supreme Yuan Realm, and he deserved respect.

Just like all beings in other environments. Even the top monks. There is also a slight difference in strength and status between them. The difference in status may be small, but if you pay attention, you can still see it.

Some of the great monks who think highly of themselves attach great importance to this.

Li Xian didn't think about it so much, and soon entered his cave mansion, launched a ban, and began a retreat.

He got a lot of good things in this exchange meeting, and he was anxious to digest them.

Those three good things I got this time. The first place on the surface should be the ancient immortal recipe, and then it will be the turn of the starfish golden sand, as well as the bottle of demon soul.

But this time, as soon as Li Xian was in retreat, the first thing he took out was the bottle of Demon Spirit.

The soul of the wandering demon, according to legend, is the soul fragments left after the fall of the strongest immortal demon in the ancient immortal realm, these soul fragments have gone through countless years, and the fragile parts have long been lost, just like the stones are constantly sharpened in the water, and Zuihou exposes the diamond in the core, leaving only a little essence of Zuihou.

These ancient souls are too powerful. It is so powerful that the little soul fragment that remains after it has fallen cannot be worn away by the years.

Therefore, only the small number of soul fragments left behind were simply pervertedly strong and tough. Among them, there is a trace of the supreme heaven and earth law that the soul master comprehended back then.

Ordinary monks can't use it, but for the great monks of the Yuan Realm, they can put it into the soul of the Yuan Shen to warm up, use the Yuan Shen to feel the supreme laws of heaven and earth contained in this soul fragment, and figure out the clues that are accidentally revealed, although they can only sense a little of it, but after hundreds of years, thousands of years, they can generally comprehend something.

Although the effect is not particularly significant, it is still very useful for the Great Cultivators of the Supreme Yuan Realm who have already stood at the peak of this realm, and it can already be regarded as a very good thing, because the comprehension of various items such as the laws of heaven and earth by the Supreme Yuan Realm cultivators has basically reached the peak of this realm, and no matter what method is used, it is difficult to make progress under normal circumstances.

So even a little bit of progress is precious.

And this demon soul is a rare thing that can definitely make his Yuan Shen Soul further progress, as long as he is willing to spend time, it will have some effect on the vast majority of Yuan Realm Great Cultivators, the effect may be very slow, but it will have a little effect, and it will definitely not go wrong.

The only downside is that it consumes a lot of time, and the amount of time is too long.

It will take thousands of years, or even thousands of years, even for the great monks of the Zhiyuan Realm, this time is too long, so long that even the great monks of the Zhiyuan Realm are a little unbearable, after all, most of the great monks of the Zhiyuan Realm will not live for more than 10,000 years, if they really put all their energy into studying the supreme law of heaven and earth in the soul of the wandering demon, it is likely that there will be no results in their lives.

Although it is not the time to warm up and comprehend this soul fragment, you can't do anything else, but it will always involve a part of your energy, and the loss is still very large.

However, despite this drawback, many great cultivators of the Yuan Realm who have not been able to advance in the soul spirit for hundreds or even thousands of years, Zuihou will still buy some demon souls, use their own soul souls to warm up these soul fragments, try it, at least try your luck.

However, for Li Xian, after he obtained this Demon Wandering Soul, he didn't plan to use it like an ordinary Yuan Realm Great Cultivator.

Because he happened to know one thing, that is, there should be a more effective way to use things like the Demon Spirit.

You must know that in terms of the use of the fragments left over from ancient powerful souls such as the Demon Spirit, there was once a race in the Immortal Domain, which was at the forefront of all the races and all the great cultivators in the Immortal Realm.

Possess cutting-edge research results.

In this regard, if the jishu is calculated by the ability of data, it should be tens of thousands, or even millions of years, ahead of the rest of the monk races in the Immortal Realm, compared to each other, the level of use of soul fragments by the two sides, the difference is simply not to be calculated.

If the level of the method of using the soul of the demon in the ordinary to the Yuan realm is the Stone Age, then the level of the great monk in that race, the level of using the soul of the demon has reached the level of supercomputing high-tech, and the main advantage is that the utilization efficiency has been improved, and the utilization efficiency of the demon soul has been increased countless times.

The name of that race is called, Lanyan Clan.

Because of that origin, after obtaining the Yuan Spirit of Yun Xiao, the strongest monk in the history of the Lanyan clan, Li Xian naturally also knew part of Yun Xiao's memories of his life, including some research results on how to use the remnants of ancient powerful souls such as the Demon Spirit.

These research results are all absolutely unpassed secrets of the Lanyan clan, but as the former patriarch of the Lanyan clan, Yun Yu knows this information very clearly, and it happened to be known by Li Xian.

Of course, these materials are the research results unique to the Lanyan clan, and only monks of the Lanyan clan can use them, and even if ordinary monks know about them, they are not of much use.

This is the difference between different racial constitutions.

Even Li Xian had to enter the cloud state to know whether the knowledge of how to use the ancient soul fragment of the demon soul obtained from Yun Xian's memory was really useful to himself.

Uncorked the bottle, and poured out countless soul fragments that shone like star sand, the soul fragments were originally transparent and colorless, but these soul fragments that had been tempered over countless years, because they were too hard, Zuihou was polished like gems.

Brilliant and dazzling.

Don't look at these wandering souls like star sand, they seem to be very fine, in fact, they are all a whole, sharpened from a large soul fragment, each other will be affected by a mysterious liliang traction, located in a fixed position in a frame, they will never leave each other too far, but they will not be too close, they will maintain a fixed distance level, even if it is the end of Shijie, it will not be separated, and it will be separated a little by chance, and it will soon return to its original form.

The way ordinary Supreme Yuan Realm Grand Cultivators used these Demon Wandering Souls was to put these Demon Demon Souls into their own souls as a whole to nourish themselves, but what the Lanyan Clan's Super Great Cultivators were able to do back then was to go one step further and completely integrate these powerful soul fragments into their own soul Yuan Shen.

It's like melting sugar into water.

In this way, the efficiency of the use of these soul fragments is naturally greatly increased, compared to the ordinary monks who have been cultivated for hundreds of thousands of years, it is estimated that they know some of the fur of the Great Dao Law contained in these soul fragments, if this direct integration is successful, everything contained in it will be known by the super great monks of the Lanyan clan - if the soul strength of those great monks of the Lanyan clan can withstand it.

Because knowing is knowing, it does not mean that they can comprehend and use it, and the monks of the Lanyan clan are stuck in another pass for the research of these soul fragments, although they can melt these extremely strong soul fragments and obtain the Great Dao Perception Law in them.

If you compare the Great Dao Laws contained in these Demon Wandering Souls to a treasure house, it is like directly opening a huge treasure house, but due to the lack of strength of your own soul, even if you know most of the Great Dao Laws contained in it, you still can't comprehend it directly, or you don't dare to comprehend it directly, so you have to store it temporarily, spend a relatively long time, analyze it little by little, and let your soul slowly accept and strengthen, so as not to contact too many rules and too strong, and your soul can't withstand it, and it will collapse and shatter directly。

To put it simply, if a demon soul is a huge treasure house, it means that ordinary Great Monks of the Yuan Realm cannot open the treasure house, and can only barely see if there are any loopholes around the treasure house, and pick up some leftovers and other things from the loopholes to make some use, and the great monks of the Lanyan clan have advanced to the point where they can master the method of opening the treasure house, but because of the lack of strength of their souls, even if they open the treasure house, they don't dare to use it, or they can't use it much, at most, they move things out of the treasure house little by little。 (To be continued......)
