Half a month later, when Xia Mu looked at the bombed pit in front of him again, his brows couldn't help frowning.

This is already the fifteenth time he has refined this explosive spirit bead, and he has not succeeded in any of them, and he can't even do the most basic condensation, at most he can barely refine it to a nearly spherical shape, but because he didn't control the fire, the energy in the spirit stone rioted, and finally exploded again.

I thought that he was learning alchemy for the first time, although his experience and techniques were a little lacking, but at least he should be able to refine the lowest-level low-grade spirit weapon like the Explosive Spirit Bead, but he didn't expect the reality to directly slap him in the face, it seems that even the lowest-level low-grade spirit weapon is not something that can be easily refined by looking at the jade slip.

Stretching his body slightly, Xia Mu first went out to see the progress of the construction of the spirit position, and then returned to the stone house again and continued to try to refine the detonation spirit bead.

Another half a month passed, Xia Mu sat cross-legged in front of the Fire Spirit Array, and with a focused expression, he played one magic battle after another against the fire attribute spirit stones in the flames, and beads of sweat the size of beans appeared on his head.

"Condensation, retraction. When the last magic battle was struck, the fire spirit array stopped spitting flames, and at the same time, a bead with a pitted surface was quietly suspended in front of Xia Mu, looking at this bead, a look of joy finally appeared on his face.

This Explosive Spirit Bead is the only time that Xia Mu has succeeded after refining dozens of times in the past month, although the appearance is very ugly, Xia Mu can feel that this Explosive Spirit Bead contains terrifying fire attribute energy fluctuations, and it seems that it only needs to be lightly stimulated by spiritual power, and it will explode in an instant.

After some induction, Xia Mu found that this Explosive Spirit Bead was not completely refined, and the furious fire attribute energy contained in it was only seventy percent of the one recorded in the jade slip, which was a defective product. However, this also made Xia Mu very satisfied, everything was difficult at the beginning, with this first success, Xia Mu believed that as long as he practiced diligently, sooner or later he would be able to refine the real low-grade explosive spirit bead.

He immediately put this explosive spirit bead into the Qiankun bag, and then took out a fire attribute lower grade spirit stone again and put it into the fire spirit array, and continued to concentrate on refining the explosive spirit bead.

In the early morning of the sixth day, when Xia Mu successfully refined the second Explosive Spirit Bead again, a look of joy flashed in his eyes.

Although the appearance of this explosive spirit bead in front of him is still ugly, the furious fire attribute energy contained in it has reached eighty percent of the genuine product, although it cannot directly bombard the early stage monk of the fetal palace, it can also seriously injure it. Although this lethality is like a chicken rib for Xia Mu, compared to the original refining dozens of times and only succeeding once, Xia Mu's alchemy technique has made great progress.

But at this time, Xia Mu still couldn't refine the real low-grade explosive spirit bead.

A few months later, after refining the Explosive Spirit Bead hundreds of times, Xia Mu finally refined a perfect lower-grade Explosive Spirit Bead, which was not only much more refined in appearance, but also had the same power as described in the Jade Slip, which could directly bombard and kill the early stage cultivator of the Fetal Palace.

Even so, Xia Mu didn't seem to have the intention of terminating, but began to try to refine the mid-grade explosive spirit bead, after all, the lower-grade explosive spirit bead was not helpful to him at all, and Xia Mu's own strength alone was enough to easily kill any early stage cultivator of the fetal palace.

But in the next few days, Xia Mu found that although he could successfully refine the mid-grade Explosive Spirit Bead, its power seemed to be far from what was recorded in the jade slip.

After thinking about it, Xia Mu thought that the grade of the Fire Spirit Array was not high enough to provide the flame of refining the medium-grade explosive spirit beads, so Xia Mu replaced the fire attribute spirit stone of the array with the fire attribute spirit stone.

If other refiners knew that Xia Mu was so extravagant, they would definitely scold him for being a loser. After all, usually refiners will specifically look for the place with the fire vein of the earth fire, and draw out the earth fire of the land of the fire vein through the forbidden formation, so as to provide the refiner with a high enough flame temperature. However, Xia Mu's move was really helpless, after all, there was no fire vein land on the barren beach for him to use, so he could only create a sufficiently high temperature flame by arranging the fire spirit array.

In fact, the original intention of the original creator of the Fire Spirit Array was to provide rootless fire for refining alchemy, but generally speaking, most alchemists or refiners would not use this method, after all, it was actually too loser, and refining alchemy was a skill that consumed resources and wealth very much, if it was consumed like this in terms of fire source, it was estimated that most people would not have the ability to learn alchemy and refining.

However, Xia Mu didn't care, after activating the fire spirit array that had been replaced with a fire attribute mid-grade spirit stone, Xia Mu began to continue trying to refine the mid-grade explosive spirit bead.

With the previous experience in refining the lower grade explosion spirit beads, coupled with the help of the fire spirit array after the shotgun was replaced by a cannon, the process of refining the middle grade explosion spirit bead this time was quite smooth.

In this way, only half a day later, the first medium-grade explosive spirit bead with ten percent power was successfully refined.

Looking at the red burst spirit bead in his hand, Xia Mu's face showed a deep groan, the power of the medium-grade burst spirit bead was enough to kill the mid-fetal palace monk and seriously injure the late fetal palace, but this was not what he cared about.

Refining the Spirit Explosion Bead was just to exercise his own alchemy skills, and Xia Mu's ultimate goal was to raise the grade of the Immortal Halberd to the level of the Heavenly Spirit Treasure in the World after tomorrow.

And if you want to refine a top-grade spirit weapon into a high-grade spirit treasure in the world, you need to refine the spirit stone into the top-grade spirit weapon, so that it can give birth to a machine spirit, which can be skipped because of the existence of the ice Jiao spirit soul in the immortal halberd. The next thing Xia Mu needed to consider was how to refine the forbidden into the Immortal Halberd.

First of all, you have to know what kind of prohibition you want to refin, for example, if you want to refine a defensive acquired spirit treasure, then you need to choose a refining defensive prohibition, such as the spirit ban that can absorb spiritual attacks, the anti-spirit prohibition that can rebound spiritual attacks, and the spirit ban that can transfer spiritual attacks, etc.

In order to refine the Immortal Halberd into a spiritual treasure in the world, Xia Mu had prepared dozens of prohibitions in advance, namely gravity prohibition, penetration prohibition, defense breaking prohibition, and acceleration prohibition......

And it will still take a long time for Xia Mu to master these prohibitions and successfully refine them into the Immortal Halberd, which even made Xia Mu want to give up alchemy for a while, and planned to directly ask the refiner to help refine the Immortal Halberd into a spiritual treasure in the future.

However, this kind of idea only appeared in Xia Mu's mind for a moment, and he immediately rejected it, practicing alchemy is not just to refine the immortal halberd into a spiritual treasure in the world, although this is Xia Mu's purpose at the beginning, but after these months of refining the spirit bead, Xia Mu was pleasantly surprised to find that his control of spiritual power has reached an extremely fine level, and what originally required five points of strength to complete, now he only needs one point of strength to complete.

I have to say that even Xia Mu himself didn't expect that while practicing alchemy, his control over spiritual power would improve to such a great extent.

Thinking of this, the corners of Xia Mu's mouth raised slightly, and he immediately began to learn how to refine the forbidden into the spirit weapon.

According to the refinement jade slip, the so-called formations, prohibitions, runes, and spiritual arts, in fact, all come from the same source, and they are a way for monks to control the power of heaven and earth through specific means, so Xia Mu is still very confident in practicing the method of prohibition.

Thinking that after the Immortal Halberd was promoted to the Spiritual Treasure of the World after tomorrow, combined with his own combat power, Xia Mu felt that he could try to challenge the Shentai Realm cultivators.

However, he just thought about this kind of thought, after all, the Shentai Realm cultivator could already launch the Divine Soul Attack Technique, even if Xia Mu asked himself that the Divine Soul Sea was strong enough, he didn't dare to really test the law.

Of course, if there was really a day when he faced the cultivators of the Shentai Realm, Xia Mu would have to make a few moves with him. After all, at this moment, it was in the midst of the war in Dongzhou, and he might meet the Shentai Realm monks of the hostile forces on the battlefield one day.

And after Xia Mu and the others were stationed on the barren beach for more than half a year, a big battle of sneak attack ambush and counteroffensive started on the other side of the Baokuang Mountain Range.

The specific situation, now that Xia Mu has returned from a mission on the front line, he learned from the mouth of a senior brother in the courtyard that it turned out that after receiving the help of a large number of strong men from the Yin Yang Holy Dynasty, the Song State actually took the lead in launching a counteroffensive and quietly lurked into the Treasure Mine Mountain Range, in an attempt to recapture this strategic border place again.

Fortunately, this matter was discovered by Xia Youlan in advance, and the reinforcements of the original nine major forces had already rushed to support in advance, so Song Guo's plan to ambush and sneak attack failed, and was even ambushed by Xia Youlan.

As a result, those powerhouses of the Song Kingdom and the Yin-Yang Holy Dynasty who had lurked in the Treasure Mine Mountain Range were attacked head-on by the powerhouses of the major forces who had been ambushed in advance on the way with an absolute numerical advantage, and they lost nearly ten powerhouses of the Immortal Realm.

Such a result naturally made the ten major forces monks led by the Qiankun Holy Academy surge, and even directly took advantage of the situation to capture several border cities in the Song Kingdom, and the high-level leaders of the Song Kingdom and the Yin Yang Holy Dynasty were naturally furious, and even some immortal realm powerhouses made a move, trying to save the decline of the war, but how could Xia Youlan let the other party succeed, and immediately invited the immortal realm powerhouses in his own camp to take action.

As a result, the two sides fought a great battle around several important cities on the border of the Song Kingdom, which lasted for several months, with tens of thousands of dead and wounded monks, and even dozens of monks in the Immortal Realm were killed, which can be called a battlefield of death.

On that day, the senior brother who returned to the hospital to hand over the task even took out a photo jade slip, and directly projected the tragic situation on the battlefield to Xia Mu and the others to watch, so that everyone secretly rejoiced, fortunately, the task they took was to garrison the barren beach, if they took the task of the front line, maybe when they would be directly killed by the aftermath leaked out of the battle of the powerhouse of the Immortal Realm.

However, the Yin Yang Holy Dynasty is worthy of being the top force of the human race in the Middle Continent, and with its support, the Song State actually resisted the attack of the ten major forces led by the Qiankun Holy Academy, and its strength is really not comparable to any force in Dongzhou.

After several months of continuous fighting, the Song monk legion led by the Yin Yang Holy Dynasty had to abandon several important border cities occupied by the ten major forces and retreat to the rear after a long period of attack. And Xia Youlan, as the commander of the ten major forces, did not rush forward, but ordered the coalition forces to rest in place, and consolidated those border cities, intending to encroach on the sphere of influence of the Song State step by step.

But just when the Qiankun Sacred Courtyard was about to take a break after months of fighting, there was bad news from another battlefield.
