In the entire border battlefield's military merit exchange treasure house, the number of spirit weapons and spirit treasures can be called one of the largest categories, Xia Mu just gave up the idea of looking at them one by one after a cursory glance with his divine thoughts, because the number was too much.

Of course, although there are many of them, there are many classifications under this category.

For example, Lingbao is divided into two categories: "congenital" and "acquired", on this basis, it is refined into "superb", "upper", "middle" and "lower", and then within the same grade, it is refined into four categories: "attack", "defense", "auxiliary" and "special", this is not the end, under these four categories, there is a more detailed division, such as "attack" is also divided into "consumable" and "long-lasting".

The so-called consumable type refers to the one-time consumption or several consumption of spiritual runes, while the long-term type can be used by practitioners for a long time, such as swords, knives, etc.

Xia Mu watched for an hour before he had a general understanding of this spiritual artifact spirit treasure.

"In terms of escaping and saving my life, it is enough for me to have the Streamer Sky Phoenix Wing and the Void Blanket, I don't need to think about anything in this regard for the time being, as for the attack, it should be enough for me to use after the Phantom Treasure Source completes the Devouring Advancement. Xia Mu shook his head and sighed: "After doing it for a long time, in the end, I can only exchange it for special resource treasures." ”

Regarding special resources, Xia Mu watched it for a while before, and the overall feeling was that the amount was large and miscellaneous, and it was too expensive, although all of them were good things, but because they were all good things, it was difficult for people to decide which one to exchange.

"Auxiliary cultivation class!" Shaking his head, Xia Mu sent out a divine thought, and immediately the Battle Merit Medal showed the auxiliary cultivation class in the special resource class.

"Only auxiliary cultivation classes with less than 300,000 combat merit points are displayed. Xia Mu once again sent out a divine thought, narrowing the range to below 300,000 battle merit points.

But even so, there were more than 10,000 special treasures that appeared in Xia Mu's mind.

Helplessly, Xia Mu had no choice but to narrow down the scope to the scope of "auxiliary physical body cultivation with combat merits below 300,000 points", and then, after screening the Battle Merit Medal, nearly 100 special treasures appeared in Xia Mu's mind.

"The water of the Thunder Tribulation, after the Nine Heavens Divine Thunder is collected by the powerhouses of the Undead Realm, it is sealed in a specially refined special medicinal liquid, and after exchange, it only needs to be soaked in it, and a vat is worth 30,000 battle points. Note: The use process is more dangerous, and it is not recommended for practitioners with ordinary physical bodies. ”

"The blood of the dragon is taken from the blood of the Heavenly Rank Dragon Clan, and after being exchanged, it only needs to be evenly spread all over the body, and a bottle is worth 90,000 battle merits. Note: The blood of the dragon contains a powerful ferocious aura, and those who are not strong in mind should use it with caution. ”

"Vajra Quenching Pill, a quenching pill made from the flesh and blood of the heaven-level fierce beast Vajra Ape as the main medicine, can be taken directly after exchange, a bottle of thirty-six pills, worth thirty-four thousand points. Note: Vajra Quenching Pill is ferocious, be sure to do what you can before taking it, it is best to completely refine the first pill before taking the second pill. ”

......

Looking at the auxiliary physical body cultivation class, Xia Mu found that the price was significantly cheaper than the "Tears of the Goddess" and "Thunder God Crystal" that he had seen before, probably only about one-tenth of them.

Of course, the latter's help for cultivation is far greater than the former's, after all, it is a treasure that can improve physical fitness and increase affinity with the law.

"With my current merit points, I can only buy these "bargains" first. Xia Mu laughed at himself, and then waved his hand, and directly exchanged all the combat exploits accumulated after entering the border battlefield to exchange these treasures to assist in physical body cultivation, as for the remaining fractions, Xia Mu chose to exchange them for some elixirs that can recover a large amount of spiritual power and heal injuries in a short period of time.

Xia Mu, who assisted in the cultivation of the physical body, bought a total of three, namely "Water of Thunder Tribulation", "Vajra Quenching Body Pill" and "Fire Flame Marrow", the first two are quite reasonable in terms of price, but the last kind of Fire Flame Marrow, the price is simply outrageous, it is exchanged by drop, one drop costs 30,000 combat merits, Xia Mu exchanged a total of five drops, which cost him 150,000 combat merits.

However, although the cost was huge, Xia Mu still felt that it was quite worthwhile in his heart, because this fire marrow could not only help people refine their physical bodies, but also had a certain chance of making the flame laws that Xia Mu comprehended merge with his physical body and cultivate into the body of laws.

The so-called body of the law refers to the physique that can urge the law with the physical body, and there is a distinction between innate and acquired, and what Xia Mu wants to cultivate is the body of the acquired law.

"The law of urging with the flesh and the law of urging with the perception of the Great Dao, the two are combined, and I don't know what the effect is. ”

"But it shouldn't be too bad. ”

Putting away the Battle Meritorious Medal, Xia Mu began to check the secret book of the "Law" that he had just exchanged in his mind, as for the "Water of Thunder Tribulation", "Vajra Quenching Pill" and "Fire Flame Marrow", because they were physical treasures, Xia Mu needed to send someone from the person in charge of the Terran in this aspect of the border battlefield to send someone over.

Speaking of which, I have to say that the high-level of the Terran border battlefield is black-hearted, because this dispatch of a special person to deliver goods to the door is to charge a thousand battle merit points. Of course, you can also choose to pick it up at a dedicated Terran stronghold, but that would be a lot more troublesome.

First, Xia Mu was too lazy to take the time to go there, and secondly, it was also out of prudence, God knows if there was any eyeliner of forces such as the Yin and Yang Holy Dynasty in the Terran stronghold, in case of what method was used to check Xia Mu's true face, the result could be imagined.

In addition to these two points, there is another reason why Xia Mu is reluctant to go to the stronghold to get it, that is, to prevent being killed by someone for money, although the stronghold is extremely safe, but if it is out of the stronghold, the situation is unknown.

In the border battlefield, as long as you are not a fool, you know that anyone who goes to the stronghold is basically to collect the treasures exchanged, so this makes many teams or lone powerhouses specially lurk near the stronghold, planning to rob people and money, although Xia Mu's strength is not afraid, but he is not idle enough to find trouble, so he can spend a thousand contribution points to solve the matter, although Xia Mu is a little unhappy in his heart, but still chose to exchange this door-to-door delivery service.

Before the other party delivered the goods to the door, Xia Mu planned to study the secret book of "Laws" carefully.

"This ......"

Xia Mu's mind was immersed in the secret book that he had just redeemed.

The secret book of "Laws" has a lot of words, 10,000 words, and the content expounded in it is very complicated, and the preface does not match the afterword, which seems to be more inclined to the category of essays, which record some fragmentary views and understandings of the author on the laws.

For example, what is a law, where does a law come from, why is the origin above the law, why the power of the law is above many power systems, and so on.

At first, Xia Mu felt that his 10,000 combat exploits had been spent a little unjustly, but looking at it, Xia Mu found that the content of this "Law" seemed to be disorganized, but in fact it had its own unique rules, or the writer explained his understanding of the law to others in a unique way.

According to Xia Mu's understanding, this secret book of "Laws" is roughly divided into nine parts.

The first part is the definition of the law, and explains to the reader what the law is through various questions and answers.

The second part is the origin and development process of the law, which tells the history of the development of the law, but it is not to tell everything, but to pick out the ten most influential periods from the development history of the law to briefly describe it.

The third part is the classification of the laws and the advantages and weaknesses of each attribute law, which even includes how to target the law, which really opened Xia Mu's eyes.

The fourth part is how to perceive the law, or how to teach people how to understand the law more easily.

The fifth part is the application of the Five Elements Law, as the name suggests, this part is about the most common use of the Five Elements Law in the entire Chaos Ancient World, which also introduces some more practical tips.

The sixth part is the application of special laws, which are about the laws other than the five elements, such as the law of thunder and lightning, the law of wind, the law of ice, the law of light, and so on.

The seventh part is about how to perfectly integrate the law into other systems, such as fusing the power of the law with spiritual power, and then using the fused power system to launch more powerful attacks.

The eighth part is about the fusion between the laws, the more powerful the practitioner, the more the law of perception is often not limited to one, how to fuse the law of perception together, exert greater power, is the theme of this part.

The ninth part is about how to further understand the origin of the Great Dao after successfully comprehending the law.

For the first seven parts of the "Law", Xia Mu can still vaguely understand most of it, after all, he has now comprehended the law of flames, but for the fusion of the laws of the eighth part and the origin of the comprehension of the avenue of the ninth part, Xia Mu can see a little foggy, mainly because his perception of the law has not yet reached that level, so even if the "Law" is easy to understand, Xia Mu can't understand it.

It's like saying that everyone understands the big truth, but if you don't experience and experience a lot of big truths, then your understanding of the big truth is just a piece of understanding.

Xia Mu's perception of the law is now in such a situation, although the "Law" is very thorough, but because Xia Mu's own understanding of the law has not yet reached that level, even if it is very simple and easy to understand, Xia Mu can still see it in the rain.

Of course, it doesn't matter if Xia Mu doesn't understand the last two parts, learning anything is gradual, first grasp what can be understood, and integrate it, then finally come back and look at the parts that he didn't understand before, maybe he will have some clues.

Putting aside all distractions, Xia Mu began to seriously study the first part of the "Law".
